The Oak Ridges Moraine Battles

 

The Oak Ridges Moraine Battles: Development, Sprawl, and Nature Conservation in the Toronto Region is a time capsule of events looking back from the year 2013, and a book that remains as relevant and important a work today as it was the year it was first put into print. Published twelve years after the passing of the 2001 Oak Ridges Moraine Conservation Act, (https://www.ontario.ca/laws/regulation/020140) this information-packed read was also composed four years before the publishing of the 2017 Oak Ridges Moraine Conservation Plan, (https://files.ontario.ca/oak-ridges-moraine-conservation-plan-2017.pdf). Historically it precedes the activism underway today to once again protect the Moraine and the Greenbelt from encroachment. However, this title has a wise voice that transcends the passing of a decade and its words continue as guidance to activists today. 

Printed in the year Kathleen Wynne stepped into power, as well as the year the ice storm and several earthquakes shook Ontario bringing climate to the fore, there was a different kind of STORM brewing in Ontario, the Save the Oak Ridges Moraine Coalition, and people were taking note. This comprehensive and detailed book was surely a welcome arrival as it would help delineate environmental action and policy. It also reinforced the astonishing breadth of support for protecting the Moraine. The writers, a smart and critically-minded team of environmentalist scholars, were also intrigued by examinations of power dynamics in coalition-forming and exposing imbalance in wider approaches to conservation. 

The book has eight chapters, each approximately thirty pages long. As we learn from our reading of Blue-Green Province: The Environment and the Political Economy of Ontario by Mark Winfield, (UBC Press, 2012) it wasn’t until the 1990’s that “the Moraine was ultimately declared an area of provincial interest, and in 1994 a series of reports on a strategy for the Moraine was completed by the Ministries of Natural Resources, Environment, and Municipal Affairs and Housing,” (Winfield, p 82).

The Oak Ridges Moraine technical committee seems to have been one of the last great things the nineties Ontario NDP government set up before it switched over, and established a much-needed first step in protection.

The Oak Ridges Moraine Battle: Development, Sprawl, and Nature Conservation in the Toronto Region functions like a sort of essential primer to these sorts of battles, and it is filled with social and political insight. Of interest to anyone wishing to learn about the history of the Moraine, the book is pertinent to any struggle against development sprawl. If you love stories of communities taking a stand, this is a book with soul. 

With plenty of fascinating historical background, high-stakes political tensions, unlikely alliances and examples of human courage in the face of adversity, The Oak Ridges Moraine Battle has one slightly unusual factor that makes it extra great. This is that the writers create a sense early on of the Moraine as an entity, and provide eloquent words of caution against simply seeing it as anything else. I think this was the most special element about the writing that made me read on. By making the Oak Ridges Moraine feel not like a landform and more like a slow-moving ancient and monolithic animal, an entity with its own agency that shifts, yields, provides, deflects and in a way even listens, the book engages reader interest from the first chapter. Once framed in this way, the effort of environmentalists to establish protections becomes a tale of people who share a relationship with earth. To this end, the book is also a bit of a toolkit for directly embracing rather than shying away from emotions in environmental causes while empowering them with facts. 

While the first chapter references Latour’s concept of “actor networks” and introduces the idea of a landform itself being an active rather than passive actor in “influencing socio-political outcomes,” (Gilbert et al., page 7), it also quickly offers some stark facts regarding sprawl and encroachment in the form of several useful charts. The following chapter, “The Surfacing of a Landform,” describes historic events involving the Moraine, its ancient function as a home to Indigenous people, the impact of European resettlement, and with a bit of humour, its only fairly recent identity as a “geomorphic feature,” (Gilbert et al., page 32). Reiterating the theme of landforms having “agency” (Gilbert et al., page 31)  it also presents the useful idea of the contemporary moraine as a “cultural construct” with “its own dynamic” (Gilbert et al., page 32), reminding us this is a place that will outlast humans.

While describing the Moraine as “shaping…human and non human destinies,” a section which asks “do moraines listen?” makes it evident the writers shared an intent to remodel our approach to scientific information with earth-centred compassion (Gilbert et al., page 33). In an age when many overly-technical books attempt to lead discussions of conservation, I found this refreshing and I believe it helped lay the groundwork for a more accessible writing style in the decade that followed. 

Further the book criticizes a dominant framework of thinking that had presided over the then-recent conservation campaign for the Moraine, cautioning against an entrenched approach (Gilbert et al., page 90). Remarking that the interrelatedness of nature and culture as well as the need to plan for biodiversity that includes humans was obscured by certain frames of thought (Gilbert et al., page 90) was courageous and, looking back, surely quite true.

The other thing I liked about this book was its thoroughness. I’m quite sure Premier Kathleen Wynne must have seen the value in owning this title and have ideally read and reread it, as I can imagine it greatly helping her in positively influencing her policy decisions and her position that the Greenbelt must be expanded.

The Chapter Nature Conservation Planning in South-Central Ontario: A Flashpoint describes the history of hearings and the involvement of Pollution Probe, Greenpeace and local action groups in defending the Moraine  (Gilbert et al., page 59). The history of conservationist science in studying the Moraine and the long history of public concern are also described in this chapter in a way policy-makers as well as everyday citizens would find accessible and informing (Gilbert et al., page 81). Charts regarding land use designation and on page 87 a list of 17 important technical papers regarding the Moraine by the Ministry of Natural Resources and the Ministry of the Environment are further listed with care. 

The chapter Residents Speak for the Moraine taught me to visualize three phases of citizen engagement in environmental campaigns, that of citizens learning the tools of activism over small disputes, of broader-based coalitions forming and finally, of involvement of the ministries, private sector citizens and all stakeholders in the concern (Gilbert et al., page 126). Of course, no book with a title like The Oak Ridges Moraine Battle could not supply readers with the nitty gritty details behind the forming of STORM: Save the Oak Ridges Moraine Coalition, and the growth of coalitions is an inspiring tale as well (Gilbert et al., page 128). While the authors have encouraged us to see these events through a critical lens, the book also gains momentum: the excitement of so many groups coming together and combining their clout is palpable. The photos are also great choices, such as the one of Raging Grannies (Gilbert et al., page 150).

The Taking a Stand chapter was perhaps the most exciting as it built on the previous chapters and made the book read a bit more like the action and adventure story it truly is. Taking a Stand, Preserving Place and Nature on the Moraine opens with a description of how homeowner groups united with environmental groups and organizations such as Earthroots and the Canadian Environmental Defence Fund. It presents both the history behind these at times unlikely alliances and the ways in which this “convergence” (Gilbert et al., page 120) occurred in real life. 

The chapters Conservation Planning in the Service of Growth and Producing Exclusive Landscape Aesthetics have some very good writing lurking within in the form of a critical examination of power issues in planning, “planning is a politics by other means,” (Gilbert et al.,  page 163) and the writing simply pulls no punches. I like that in a book, and the statement that “ the Oak Ridges Moraine is a privileged residential environment,” and that it is still “vulnerable to development pressures” underscored the issues involving classism and other buried concerns (literally in the case of Indigenous sites) that sometimes go unmentioned when coalitions combine. Both chapters were sobering after the excitement of large coalitions joining forces, and the adept writing shone a much-needed light on how much work is still to be done. The writing in the chapter Producing Exclusive Landscape Aesthetics quite brilliantly exposes the untruths behind the capitalist notion of “win-win ecology” (Gilbert et al., page 225) and the hypocrisy of aggregate companies presenting themselves as “good stewards.”

 In conclusion, this is a book that is successfully timeless and the authors write with skill. It contains a lesson in perceiving any geographic landform (and by extension our planet) in a wholistic and respectful way, and it is a book loaded with indispensable information. Highly recommended.

An Introduction To Environmental Law and Policy in Canada

 

I discovered this book while checking out the required reading list for courses at York’s Environmental Studies program. It’s used in an Environmental Policy course, and I couldn’t resist buying it for study.

This opening chapter explains the law-making bodies in Canada, the reading of bills in the House of Commons and the process required for laws to come into force both in federal as well as in provincial systems. It moves forward to explain, “The Concept of Jurisdiction,” and it uses a case example. This was the first use of a real case example in the book. It created a reassuring sense we had moved beyond introductions and into the realm of actual legal textbook, and that this was one that is designed to equip that environmental law literacy so needed in our future courtrooms. 

The chapter end then provided a summary of key points. My assessment is that this chapter definitely met learning expectations. It also offered interesting discussion questions and it dished up enough suggested readings to occupy a keen student for quite some time.  

The next chapter, Aboriginal and Environmental Law, presented a case study example by the second page, something as a reader I found exciting. Case studies create for me an instant sense of connection to the legal process and the history of legal challenges. The chapter explains that Aboriginal law and environmental law are intertwined, and discusses terminology (such as the word Aboriginal) in a clarifying way. It also describes well the idea of treaty rights, thankfully explaining that they are wide in scope and that some land is also unceded territory. 

The 1990 R. vs. Sparrow case, a study of the Delgamuukw vs. British Columbia case in 1997, The Taku River Tlingit First Nation vs. British Columbia case (2004) and the Haida vs. British Columbia case (2004) are all presented here, as is Tsilhqot’in Nation vs. British Columbia in 2014. It was great to see the extensive presentation of these case studies, in most cases important precedent-setting wins. Studying even a rudimentary description of these cases helps any reader better frame compassion for Indigenous people’s struggles in a legal light and these are written in a helpful and compassionate way. 

The chapter then returns to the discussion of treaties and presents the Grassy Narrows challenge in 2005. Here I did feel that, although the description emphasized expectations regarding the duty of the Crown and of the Province of Ontario, because the pollution concern at Grassy Narrows is far from resolved, it seemed an omission to only describe the “duties” aspect and have no mention of recent failures of duty as Grassy Narrows is still an ongoing battle for environmental justice today. Excepting this feature, the chapter is a very good introduction to the issues and a very useful explanation of how these challenges occurred in court. The chapter also conveys the importance of consultation and accommodation, and how these are key to and work alongside environmental law. Again the chapter-end discussion points were useful and the suggested reading list and notes are extensive making it a very good introductory chapter that fulfils its goals for learners.

The next chapter, Chapter 3: The Relationship Between Canadian and International Law, has three learning objectives. The first is to grasp the meaning of International Law, the second is to learn key components of both conventional and customary International Law, and the third is to know the history of Canada’s involvement in the development of International Law. 

The chapter begins by emphasizing the complexity of International Law and that there are many types. It explains Conventional International Law clearly and usefully. Conventional International Law involves conventions or treaties between nations with carefully set out (and specific) terms, and their arrangement is formal. Negotiations can take years and have many stages. Agreements regarding a change to details in a convention or treaty, legally termed protocols, are a much less formal process. Protocols allow for developments to formal conventions or treaties and draw attention to specific parts. While protocols also can take years and must be entirely agreed to by participating nations, their terms do come into effect upon ratification. The chapter also explains how Customary law is different than Conventional law, as Customary laws are based upon long-standing laws recognized to be binding and abided by. The book then discusses several case histories, and presents examples of times Canada has played a role in development of International laws. Here I appreciated that the book included the fact that Canada has recently been seen as obstructive in the case of international Environmental laws.

This chapter concluded, consistent with the others, with discussion questions and ample numbers of notes and suggested readings.  

The final chapter, Environmental Assessment, begins with a frank introduction that explains assessments as controversial and outlines how they meet resistance, although assessments often serve to make great progress in protecting the environment as well. The book outlines some useful background history to environmental assessment law. Progress in this area has definitely included better public participation and prevention rather than corrective action, meaning the pushback is less from communities and more from companies hoping to exploit a location for resources without reasonable restraint. This chapter also describes the history of assessment law in Canada, and describes it quite accessibly, making it an interesting piece of writing to any student intrigued by the field. Finally, it also provides a chart breaking down the differences between basic and more advanced assessment law in Canada, and reviews newer concepts of sustainability in law.

 All in all, I found this final chapter entirely readable, building well upon what was covered in earlier chapters, and creating for the student a feeling of accrued ability. Notes for this chapter run for three pages and the chapter’s suggested reading list and discussion questions are intriguing. As well as having key terms list at the end of each chapter, the book concludes with an extensive glossary, The glossary is also worthy of study and is eight pages long.

 I really enjoyed the offerings in this (75 page student version) textbook and I’m glad I purchased it. It contains a comprehensive introduction to the field and is well-written in its aim. An excellent understanding of not only Canadian environmental law but international law and the history and development of treaties and environmental laws between nations is within its pages. For any student ardent about environmental justice, An Introduction to Environmental Law and Policy in Canada is an indispensable primer.

Recycling the City: The Use and Reuse of Urban Land

 

This book offers policy ideas and asks questions regarding underutilized urban land. Although it was published in 2004, it is entirely valid today. The editors, Rosalind Greenstein and Yesim Sungu-Eryilmaz, wrote this as a publication of a Cambridge, Massachusetts think tank called The Lincoln Institute of Land Policy, which has existed since 1946. The Lincoln Institute of Land Policy currently lists as its goals: Low-carbon, climate-resilient communities and regions, Efficient and equitable tax systems, Reduced poverty and spatial inequality, Fiscally healthy communities and regions, Sustainably managed land and water resources and Functional land markets and reduced informality (Wikipedia, 2023). This large, oversized paperback with full colour photos is divided into three parts, and each one of these sections has three to five articles by contributors under their topic. 

Part One, The Vacant Land Phenomenon, encourages readers to see vacant land as opportunity and challenge. This creates an optimistic tone that is an excellent lead-in for the rest of the book. The section defines Vacant land, and asks why such land is found abandoned in cities. It raises several questions. Why do these underutilized urban spaces appear in city landscapes? Why do they remain unused for long stretches of time, despite an obvious need for their deployment as gardens and community spaces? 

Leading into Part two, The Vacant Land and Brownfield Redevelopment process, the book discusses the assessment tools required to determine if an unused parcel has a history of being contaminated, always a first step before redevelopment can get underway. We learn that there are considered to be at least three classes of brownfield sites involved in assessments, at least in American cities. In my own internet search, other environmental assessments seem to have six or more Tiers, but the Tier system is always an important assessment feature. This is also perhaps a window into the problem of the gentrification process, as the Tier process seemed very linked to the salability potential of any land. As found in this (American) book, Tier One abandoned sites, regardless of their location or the better purpose a community may see for them, are sites designated as the most attractive to the private sector. Tier Two sites are those classified as below the threshold for development viability. Typical Tier Two sites seem to include spaces such as waterfront sites in cities with low economic prospects, defined as Tier Two when they have some risk of contamination, and so will require work to bring them into a marketable category. 

This process is also clearly outlined at the website https://www.lincolninst.edu/publications/articles/overcoming-obstacles-brownfield-vacant-land-redevelopment, which is produced by the same Lincoln Institute of Land Policy that published this book and so has consistent information in both places. Sites with a Tier Three status are sites that require considerably more effort and investment as they have a proven contamination issue that is not easily resolved. Once sites are assessed and are redeveloped, Innovative uses for Vacant Land as described in Part Three, can really take on a life of their own. Innovative uses for Vacant Land can include community playgrounds as well as community gardens, fruit tree orchards, gathering spaces, spaces for theatre, workshops, concerts and other performances, Tiny Forest sites, and many more. Greenhouses, small outdoor cinemas and outdoor galleries also can be included here. 

I found this book fun and useful. It has action in mind, and it’s difficult to read it and not feel like the expertise accrued must be put to good uses. I hope this book stays in print, as the 2004 publication date only shows it has been a well-spring of knowledge for several decades  of vacant lot repurposing, and is in fact, a bit of a hidden classic.

Blue-Green Province: The Environment and the Political Economy of Ontario

 

This book has beautiful clear maps and charts, and is an under-discovered gift to the people of Ontario. Whoever decided to create a free download option for avid readers has done a great service, and I can only hope that as many Ontarians as possible are reading this volume. Blue-Green Province is a go-to read-and-reread reference book, and not a book intended to be absorbed by skimming through once. The author is a meticulous scholar, and has an understated nonpartisan style while placing successive Ontario governments under a brilliant environmental lens. 

Winfield addresses his potentially vast topic with scrupulous diligence and his professional approach includes extensive and specific notes to important events that would have otherwise been lost in the archives of government data. His authority is indisputably the product of an exacting writer devoted to the merits of his work. Blue-Green Province as a history book divides its sections into a intriguing and entirely readable study of Ontario government eras. Turning point moments in Ontario's environmental policies are described by Winfield  in a compelling and coherent way. Environmental scaffolds in place today are suddenly made stark for the readers as the efforts of years of laborious process on the part of environmental advocates who have fought for decades, and fought in decades past to create accountability in this province. 

The preface reminds us of Ontario's record of great environmental achievements as well as several historic calamities, transporting us as far back as the 19th century which marked some of the beginnings of action on the part of policing the environment (Winfield, xiiv). Winfield also goes back to the forties and even thirties and references the governments of Frost, Robarts and Davies, and successfully creates needed continuum regarding the history of Ontario in the process (Winfield, page 6).

The book, as an environmentalist history, but rather than being structured around time periods, it is structured around specific government eras in Ontario. The effect of this approach allows readers to slowly build upon their Ontario environmental issue literacy, and use it to contrast the management and policy decisions of Ontario today. This creates for readers a sense of the urgency in past times, when Ontario’s environmental realm was entirely unregulated, and a look at how legal loopholes were left behind by successive governments that placed production above protection. Blue-Green Province gives an overview of past environmental records from each government era, beginning with the long PC "Dynasty" period, a daunting process something Winfield has written in a fairhanded manner and researched extremely well. The entire book is accompanied by footnoted text, providing several footnotes within each paragraph throughout. It is reassuring to read a book by an author so dedicated to ensuring academic sources are present and in place.

Another plot in the book is the tug-of-war between Ontario's private sector, who wanted to extract resources and pollute with a free hand, and environmental lawmakers, who wanted them to comply to environmental regulations, which were developing in response to a greater understanding of the harm pollution caused. Winfield uses the term "incremental" to describe the incredible slow pace and deliberately stalled progress and exemptions-making route that basic environmental regulations and their enforcement took in Ontario (Winfield, page 32). The book is also great at identifying key moments in time, such as the establishment of the Environmental Assessment Act in 1976 which resulted in the government being willing to actually consider prosecution for hazardous waste pollution by 1980 (Winfield, page 32). Blue-Green Province effectively recreates the controversies and challenges of the time and makes understanding these important historical events much more interesting as Winfield is a writer who is skilled at removing obsfucation and letting facts speak volumes.

For me there were many interesting moments and parts in the book, including the acid rain battle (Winfield, page 65) and Winfield's description of the Harris government, and the ways in which Harris sought to undermine past regulations, as well as the legislative and other responses to his attempts (Winfield, page 106). 

I highly recommend this book as there is great inspiration between its pages. Anyone who wishes to develop their literacy regarding the evolution of Ontario's environmental protection policies, the history of how they came to be in place and a sense of what more must be done will find Blue-Green Province unparalleled.  

If there is a term for dog-eared favourite in the electronic realm, I highly recommended this essential volume become a dog-eared go-to for all Ontarians. The contents are easy to grasp and important for every Ontarian to become versed in. It is an important work of outstanding academic calibre accessible to all.

Facing The Climate Emergency

Facing The Climate Emergency: How to Transform Yourself with Climate Truth is a book with an ambitious intention. Authored by Margaret Klein Salamon with an introduction by Molly Gage, the book is written to create climate activists. A slender volume, the first few pages are packed with praise from twenty-eight reputable editors, authors and directors of leading organzations addressing climate change today. Among the added remarks on the back cover, the co-founder of Extinction Rebellion writes, "This work is not optional. Read it, use it, and rebel." The book's introduction is indeed extremely readable, and, like the rest of the book, it has a therapeutic tone, frankly discussing the challenge our society is facing regarding painful climate change truths. Such an accessible opener invites readers at any stage in their understanding to drop in and join the larger conversations in the book. This book also pulls no punches. The author presents the opiod epidemic and other mind-numbing addictions our society partakes in, remarking, "It is hard work not letting yourself feel your fears. When you avoid the truth, you put the energy that could be used towards preventing the climate emergency into safeguarding the fiction you've created for yourself."

While I was immediately impressed with the connection I felt to the writing, it was the breakdown of psychological factors involved for humans looking at climate change that really hooked me to read on. These factors included those of "Willful ignorance" and, my favourite, in true activist style, "Regression: We need the experts to handle this." From the first pages this book also names CEO's and specific corpoprations associated with blocking efforts to stop climate change, as well as making clear just who are the heavy hitters in working to stop climate change in various fields. Following an activist-rousing introduction, the book is divided into 5 sections, titled Step One, Step Two, etc., while the concluding Step Five, "Join the Climate Emergency Movement," offers detailed advice in a direct address to readers. It was an open invitation to all those seeking roles, purpose and action.

Step One also compares our curent lack of emergency response in comparison to "Allies entering emergency mode when mobilize to win WW2." This is a strong case, and I hope people take much inspiration from the example. As the authors remind us, "faced with the prospect of annihilation, Americans and Britons were expected to pull together by working in war jobs, growing victory gardens, contributing to scrap drives and -in Briton- volunteering as Air Raid Precaution wardens." I've heard the comparison before, and I welcomed encountering it in this book. Today, the book remarks, "this sort of necessary response is required but has yet to be engaged." I have to agree with the authors. This book is toned as an action call throughout, and I find it excellent. Any shortcomings have to be assessed given the purpose for which it is written. The author is brilliant in describing the way that movements can bring social truths to the fore, such as the #Metoo movement, or the civil rights movement, and other movements that allowed society to address injustices that were in some cases sensed but denied. They also discuss the "gradualist movement" which wants change done the books argues in such a gradual way that it is useless. It presents instead the climate emergency movement: "this movement demands what is necessary- a ten year transition to zero emissions plus drawdown." After such a strong opener, we wonder what is next. What exactly is "Step 2?"

Step 2 turned out to be a bit unexpected. It phases readers into a twenty-three page discussion of emotional work and of skills required for dealing with the fear that arises from facing climate emergency. It's a surprise to encounter this in a book of this sort, but an incredibly cool feature. The author also openly discusses how they sought psychotherapy for their own anxiety around climate crisis, an honest tone for a difficult topic. And, as in every chapter, a series of questions about the text are available at the end. For Step 2 the questions were personally challenging but excellent and I hope that personal emotional skills structured around Step 2 will help quell conflicts within the movement in a way that other movements may have overlooked.

Step 3 "Reimagining Your Life Story," is a chapter for people revising their personal script. It talks about heroic models and "saving the planet" in a way that addresses the reader's new information, cautioning against personal gradiosity contrasted with the need for everyday heroism.

Step 4, "Understand and Enter Emergency Mode" posits that human responses to crises, "fight, flight or flee," as well as writings on PTSD "contribute to collective paralysis." This is an example of a point in the book when I feel it is perhaps directed at a white middleclass readership. The statement is used to present the argument that, "these are not our only options. We can also be inventive and collaborative in our response." I find this opener a bit objectionable, even though it is building into a pitch for emergency action which is worthy, as it could stand to have been a bit more nuanced. It's not as if people simply choose PTSD, as much PTSD occurs to children, and the PTSD movement itself involves an army of inventive people who, for the sake of society, have accepted both diagnoses and drugs before recent healing breakthroughs that serve us all.

There were a few other points in the book where I thought the authors were lacking sensitivity, and I don't like "forgiving" anything I read as I go, but I did understand the message and intent were also well-intended and good. Because of the urgent message, I wish there weren't these points I object to, because ultimately, it is a super cool book.

Step 4 offers an historic distillation of some of the emergency responses (such as the Allies's rally to win WW2) but is perhaps my favourite chapter because it presents Larry Kramer and the ActUp! movement of the Eighties as a prime example of citizen action when "gradualism" isn't effecting change. This and other examples of emergency movements that created effective and lasting social change are what make the book great. It's an inspiration and call-to-action tome and very effective in its purpose.

I enjoyed this book and I actually cant reccomended it enough. Five stars, it was a dive into a cool and refreshing ocean of like minds engaging their democratic citizen duties by stepping up.

Public Gardens and Livable Cities: Partnerships Connecting People, Plants, and Place

Authors Donald A. Rakow, Meaghan Z. Gough and Sharon A. Lee have compiled a series of studies of public gardens broken down into six parts. The introduction addresses the urbanization of the future world, and the need to define and prioritize livability as distinguished from sustainability. It presents public gardens as "anchor institutions" just like libraries or parks, rooted in their physical location. Emphasizing the importance of partnerships between public gardens and organizations outside the gardens, the book explains types of partnerships in communities. Cooperative examples would be a garden shared by a school, while collaborative partnerships are those that share resources and decision-making while remaining independent. Collaborative partnerships are generally considered to be the strongest type. The final stage for any type of partnerships is collective action, which includes a shared committment to collective impact and a common agenda for moving forward.
The first chapter, titled, "Promoting neighbourhood safety and well-being," examines cities across the United States where there is a demand for more livability while introducing the idea of placemaking, a strategy that uses public spaces to promote social interaction and, of course, partnerships. The book examines many public gardens, and I will mention a few of my favourites here. In Brooklyn, the Brooklyn Botanical Garden's Greenest Block Competition is a gardening initiative that has created an enthusiastic following and has improved public spaces throughout the borough. The Ambassador Program at the Queens Botanical Garden in NYC, like the Greenest Block competition, has powerfully developed community and built trust. However, I found the description of vacant lot programs particularly cool. Chapter one describes the Philadelphia vacant lot situation and the initiative of the Pennsylvania Horticultural Society in setting up a LandCare program in the 1970's, now one of the biggest vacant lot land programs in the US with over 12,000 properties. PHS has partners around the country, and participants come to Philadelphia to seek assistance from the PHS staff in designing a vacant land strategy for their own city. This chapter concludes with a topic I always look for data about, the issue of gentrification and the "long-term implications" of "beautification vs potential for resilience" regarding those newly-greened communities that have surely earned the right to hold onto their neighbourhoods and resist displacement.
The second chapter, titled, "Improving the quality of science education," addresses the job opportunity, safety and environmental sustainability spin-offs generated by community greening projects. It describes project Green Reach, which has helped Brooklyn kids grades K-8 access science information and observe nature's cycles first hand. This type of project was repeated in many other cities, including Chicago, where science class gets awesome as Chicago Botanical Garden students extract DNA in mentorship with research scientists. There has been a huge upswing in interest in urban gardening as a result of these efforts. By 2013, 2 million more households report involvement in some way in community gardening than those in 2008. In the case of Bronx Green Up, participants are awarded certificates for learning levels and skills gained, as well as practices implemented. Green Corps in Cleveland also does this, involving local teens while bringing fresh, organic produce to underserved neighbourhoods and selling produce at local farmer's markets each week. Green Corps is in an interesting partnership with the Cleveland baseball team, and maintains raised beds at the team's stadium as well as in the player's parking lot, with produce used by the team chef to prepare healthy dishes for the players.
Access to healthy food and promoting healthy lives through urban gardening partnerships are discussed in Chapter three, while Training and Employment programs are addressed in more depth in chapter four. Public gardening job training programs for veterans and an examination of the Riker's Island greenhouse program are included. The RIGP is a partnership with the department of corrections and the department of education, and develops horticultural skills while citing a forty percent reduction in recidivism as a spin-off of the program.
Chapter five explores initiatives to promote ecosystem and human health, while "strategies for the development of successful partnerships" is explored in depth in chapter six.
This is an amazing book. I truly enjoyed reading this volume and the enthusiasm regarding gardening partnerships shifted my own thinking in positive ways. The epilogue supplies a look at the future of public gardens and the book is made yet more accessible with extensive appendixing. Recognizing public gardens as anchors and the key to healthy communities is one of the most important message of our times. This energetic, reader-friendly book with many photographs shines a persuasive and motivating light.

City of Forests City of Farms: Sustainability Planning for New York City's Nature

Lindsay Campbell is a Research Social Scientist who received a close-up view of the massive PlaNYC 2030 and its accompanying MillionTrees Project roll-out from her job posting within the US Forest Service's NYC Urban Field Station. Sustainability plan PlaNYC 2030, which began in 2007 with great fanfare under the mayorship of NYC mayor Michael Bloomberg, included a $400 million commitment to plant one million trees in NYC. This colossal project, under the direction of the NY Department of Parks and Recreation, inspired tree planting campaigns around the world.
In contrast, "urban greening practices such as urban agriculture, community gardens, and other interventions into local food systems received no mention in the 2007 version of PlaNYC." This omission occurred despite the fact that New York is home to "one of the largest networks of urban community gardens in the world."
Campbell asks, "why were urban forestry and agriculture treated so differently in the sustainability plan?"
While there are parts of the book that suggest Bloomberg was willing to leave the urban gardening movement high and dry, the real reasons and the politics at play in urban greening are more complicated. Certainly, from the onset, decision-makers involved in PlaNYC had a commodified view, describing the value of trees from an investment standpoint, while there was a perceived gap in any metrics regarding the value of urban farms and community gardens. Campbell was able to document how, over a number of tense seasons and against considerable odds, activists, researchers and everyday citizens replaced that gap with the measurable science and data that was missing.
Because of the "sales pitch" approach by advocates of PlaNYC 2030, the stakeholders in this form of "green growth" were very distinct, and the process of deciding who gets to set the agenda was considerably influenced by NYC's business elite. In the context of this difficult onset, grassroots activists, urban farmers and community gardeners throughout NYC organized and prepared a successful challenge to the forestry-led agenda by 2011. Campbell's journalistic book shines an intense light on various developments in PlaNYC2030 from 2007 to its more urban agriculture-friendly revisal PlaNYC 2.0 in 2011 to its continuing implementation up until 2015.
Urban agriculture while "entirely absent" from the first PlaNYC, was not at rest, and until there were serious and ratified goals set regarding the production of local food, activists were agitating for change.
Campbell found this touchpoint interesting enough to carry the book, and I think it does. The book is a very thorough biopsy of a time period in which a gargantuan effort was undertaken to transform a city. Without a strong challenge from social justice and grassroots urban agriculturalists, the Bloomberg legacy might have resulted in a very different picture.
The book supplies excellent charts in this book before even the close of chapter one, extensively comparing the urban forestry network in chart-form with that of the urban agriculture network. "I pay particular attention to how ideologies of environmentalism, sustainability, and neoliberalism overlap or compete," the book"s author declares in the introduction, and I believe she bears this claim out.
In examining the absence of food policy and planning in the PlaNYC 2007 strategy, we learn that food policy in those days was seen as something too vast, complex and too controlled by the private sector for any city government to bring under their jurisdiction. At the time, small-scale community gardens were not the only ones who felt leery of Bloomberg's plan. By the time the revised plan PlaNYC 2.0 rolled around in 2011, it was however positively influenced by food policy goal-setting changes. However, it was a hard road to arrive at that juncture. As well, some of the more mainstream critiques of Bloomberg's "sustainable city" initiative during the establishment of PlaNYC 2.0 insisted that the sustainability planning did not consider "the hinterlands and global commodity food chains" on which the cities were dependent. Other critics felt that sustainability plans in their current form did not challenge the political-economic structures of cities sufficiently to create real change. While PlaNYC pandered to commercial interests and received a huge amount of funding from NYC's business elite, it was also a model of independent municipal problem-solving and in many ways ahead of its time by tackling climate change and urban heat issues head on.
Not surprisingly, PlaNYC 2030 began with an idealistic but uniformed leadership driven by Bloomberg's dream and the project's considerable funding. In the early days, "sites were viewed by decision-makers as just green spaces on the map that could receive hundreds of thousands of trees." As a result many advisors quickly "took issue with the numerical tree planting goal and correctly argued that emphasis should be placed on creating healthy, native, multistory forests" because many sites for these early tree planting proposals had "nothing to do with feasibility."
By chapter six, Campbell has led us through some interesting years and forward in time beyond the Bloomberg years and into the de Blasio mayoral era. The de Blasio era was a time when the emphasis on social programming became more central than the trees. However, by this point in time, NY's urban grassroot's gardening movement had gone into gear. Here Campbell describes in detail the establishment of vast and entrepreneurial rooftop garden operations in NY. The demographics of the gardeners, the backyard chicken program participants and the beekeeping programs in NY are well-chronicled and reassuring reading regarding how some of these sustainability initiatives are playing out.
However, the impression that poor neighbourhoods and the people who live in them can be upgraded en mass did take its toll on NYC. It is well-known that treeplanting can beget gentrification. A number of ground-level garden sites were negotiated sites, for instance planted in movable beds, with the understanding that the site was not able to be affordably developed at that time but in the future would be turned into housing. This discussion is to me the most interesting, because the idea that the urban poor are intended to improve and move, or to continually shift to make way for development as a sort of civic duty, is highly problematic.
Fortunately, over the years of the PlaNYC 2030 sustainability implementation, there was a lot of emphasis on research. As well as research groups, activist groups such as 596 Acres sprung up, assisting in the visualization of those hundreds of vacant urban acres that required farming. Rooftop farm entrepreneurs as well played a role in urban food agriculture and their gardens were also included in the 2011 PlaNYC 2.0 revision.
Ultimately the urban agriculturalist won their point, and urban agriculture became ensconced within the 2030 goals. These goals included the assessment of land availability and suitability for urban agriculture, the creation of citywide urban agriculture program, and the ensured permanence of community gardens. The development of rooftop agricultural greenhouses, a determination of the capacity of the regional foodshed, and the development of state strategy for farmland and food production were also included. Barriers to food composting in community gardens were eliminated and agreed-upon goals to expose all city students to farms and gardens were also established. By cultivating student and citizen access to agriculture and relationship with an urban farm, a generational literacy in food production is today fostered. These were only some of the changes and goals set out in the document, many of which have been implemented, and their positive impact is clear.
The final chapters including one titled "Constructing the "greener, greater city" describes how there is no longer a lack of data now but "a proliferation of academic research and citizen-led science on urban agriculture..." and examines how much the planning implemented under public health rather than competitiveness functioned as programs for the sake of social justice. Soil testing, contaminant-free healthy and fertile soil and other ensconced PlaNYC 2030 sustainability values are also discussed.
How have things fared post-Bloomberg? The millionth tree was inevitably planted with great volunteer engagement. Even though de Blasio moved away from tree planting and slated over a dozen garden sites for development, "urban agriculture is on an upswing" regardless of city governance.
In closing Campbell looks to the urban farm movement future with hope that this movement can achieve "the critical mass necessary to scale up and affect citywide policy and natural resource management." Her challenge lingers long after the last page of the book.

Globalization and Urbanization: The Global Urban Ecosystem

James H. Spencer has worked with numerous NGO's and has taught urban and regional planning and political science in Hawaii and California. Instead of discussing rapid urban transformation in the North, this book takes a look at the places in the South where changes are occuring at an unprecidented scale. This rapid urbanization is most evident in South-East Asia, China, and Sub-Saharan Africa, where fast-paced changes are creating interesting challenges for city planners. Remarks the first chapter, "today we can watch patches of five-hundred-hectare developments in China, Vietnam, India, and Abu Dhabi sprout up almost overnight out of what only months before were pristine wetlands, hillsides and deserts."

While his interest is urbanization in the Global South, Spencer includes writing about places like New York City, and I found his chapter on New York regarding the forces that formed that city to be particularly insightful.

The first chapter, The Global Urban Ecosystem, describes a fascinating history of human civilization as well as the "emerging discipline of ecosystem science." Spencer asks, "what is a city?" and how does it change our personal identities? How do we adapt our behaviours, and how do animals who are impacted by the detritus of cities change and adapt? Clearly cities shape a larger ecology. “Because humans build, occupy, and transform them, cities come alive and develop personalities that represent many people,” says Spencer, sharing collective history and relationships of residents into complex interacting forces. The science of cities is never entirely reliably or empirically measurable as there are so many “second-order categories” that make it difficult to study cities unless they include race gender, age, cultural and socio-physical factors that are difficult to standardize. Here Spencer vividly describes the evolution of human gathering places to actual settlements with markets and resulting economic roles. Spencer's writing is rich in references to other scholars of urban development, and his discussions of Jane Jacobs's ideas and frequent references to Jacobs's work are admiring and set an upbeat tone.

Chapter two offers a deeper historical context to the phenomenon of urban growth, including a "natural history of the city," and a section introducing Lewis Mumford, considered the patrirach of urban planning. Spencer compares Mumford's ideas to other scholars such as Jacobs and later introduces the ideas of planners such as Frank Loyd Wright and Ebenezer Howard, founder of the garden city movement. Here it becomes clear utopian ideas in compassionate, human-centered city design and the garden city concept are important ideals to Spencer. “Utopian planners have long dreamed of an ideal society in which cities and settlements achieve human-scale interactions, social equity, and connections to the environment.”

The book then begins a multi-city tour of those places that Spencer has chosen as interesting comparisons in the urban realm. Here Spencer introduces the concept of "Do-Your-Timers" for people working in cities where rewards hover as potential and in the future. The first city Spencer has chosen is Saigon. Saigon is a city growing very rapidly yet there are still people who cook on open fires inside the house and do other things that identify them as rural people new to urban living. Only China is growing more quickly than Vietnam in terms of GDP. Vietnam signed a trade agreement with the US in 2000 that radically changed markets. As a result entrepreneurs have also flooded into Saigon from China as well as places as far away as North America and Africa to try their entrepreneurial luck. At the same time, Saigon is a textbook example of rural migration, with people coming in from rural places such as the Mekong Delta creating a population of new "Do-Your-Timers" whose numbers swell the labour force but also thwart city planners. Saigon has drawn people from many walks and has a surprising level ofnewcomer diversity. It is not just farmers who have become urban factory workers, as rural people have created an extensive economy including quasi-legal businesses on the fringes offering services such as haircuts and massage for new urban consumers.

In chapter four, Spencer turns his attention to the city of Addis Adaba, titling his chapter: "Do-Your-Timers" African style: Addis Ababa, the Unlikely Capital of Africa. This chapter has some excellent history about a very distinct city that is growing quickly, including through the migration of thousands of Chinese workers into Africa. The chapter describes how Addis Ababa came to be, its unique qualities and unusual aspects that make it an interesting point of study. In particular, the history of the region is unique. Ethiopia has never really been colonized by a major European power. Italian intervention in Ethopia ended after a decisive battle, and emperor Haile Selassie remained monarch from 1930 to 1975. During emperor Haile Selassie's reign his image was elevated with the establishment of Rastafarianism and the granting to hundreds of Jamaican families of Ethiopian land in an area just south of Addis Ababa.

With the overthrow of the royal lineage in 1975, a development strategy built on the model of the Soviet Union was attempted. There was a period of rapid growth both in terms of population and infrastructure, before a civil war put everything on pause. Once stability was restored, a modern airport arrived in Addis and it was made the home of the African Union, a designation which radically changed the character of the city as global investors could suddenly access the city. Interestingly, Addis Ababa still runs on a precolonial time clock and a unique calendar that would normally limit its ability to do busness. Added to this, Ethiopians speak a variety of local dialects, none of which are common in other parts of the African continent. However, the strong role the area has played historically make it a preferred choice by many international business people, including those who have flocked there to escape war or plan business in other parts of Africa, such as Kenya. Although China is investing highly in South East Africa, Sub-Saharan Africa is receiving a massive foreign investment growth rates as well through Chinese investors. Africa is also poised to be a massive market for China not only for things such as phone and technology services, but for many goods and commodities as well. At the moment, 64% of oil is shipped to China from Africa, but these arrangements appear "poised to expand" to mutual benefit.

Chapter five, The Indigenous City? Reconcycling an Old-Timers' Honolulu with a Global Society begins with a description of the lush beaches and beautiful Pacific mountains. The writer then remarks that to drive around Honolulu is to also discover that "the city and county of Honolulu-is a city of pack rats...its residents are accumlating and storing both material goods and garbage, as well as experiences, ideas and aspirations, faster than the pristine and isolated island can cope with them." The author describes it as a city "stranded in an ocean five thousand miles from the nearest major landmass," with a special series of challenges as a result. Spencer quotes Mumford in his assertion that for the residents of Honolulu, living among "lush tropical trees, plants, flowers and bushes," may have given them "license to neglect its insufficient physical infrastructure." Spencer describes the significant diversity of cultural infuences that define modern-dsy Honolulu, including the enduring legacy of the original and contemporary Polynesian culture on the place, as well Japanese and Chinese cultures, and a massive influx of tourists from the mainland United States, many in the form of sunbirds who stayed, bringing considerable wealth and an entire tourist and service economy with them. Recently the idea of "Ahupu'a" has been touted by Honolulu as a way to attract investors as well as convince international interests that Hawai'i is conforming to environmental practices. Spencer explains the concept of "Ahupu'a" is an ancient Haiwaiian land governance concept that creates a structure for a limited area of "complex socio-ecological regions" as a single place. The author also expresses doubt that, given the level of neglect some communities receive including that of basic sanitation services, "Ahupu'a" as more than a marketing ploy is not truly at work in Honolulu. The chapter examines a series of trends, including challenges with waste management, NIMBYism, the plight of poor and "minority" neighbourhoods, and underlying political crisis in in its identity as an "Old-Timer's" city.

The author suggests that Honolulu must not assume that much-needed change will develop naturally, but that great planning will be required to protect the poor and allow them the ability to escape slum-dwelling and participate in the economy of Honolulu, which is propped-up powerfully at the moment by tourism and service industries for the wealthy.he comments that just like the Hawaiian tourist industry was developed with the importation of sand from beaches as far away as LA., growth in Honolulu, if it is to avoid slums, must be planned to prevent urban sprawl by deliberately creating opportunities. a range of opportunities and services that support the poor of Honolulu are as essential as those that cater to newcomers, while efforts to equitably integrate the labour force with the tourist industy that sustains the city rather than allow tensions to remain unresolved will be the road to a more peaceful and equal city longterm. Whether this will deliver "ahupua'a" or simply provide a stronger footing for improving the lot of Honolulu's poor, the sudden differences created by tourist colonialism are a long way from a dream of a "new communalism" and must be addressed.

Chapter six, For All-Timer's New York City's Empire State of Mind was my favourite chapter, despite the fact that the author was not writing on a city in the South. Spencer found New York important to include because, in part, we think of New York as the quintessential city when it is actually much smaller than many cities and has many unique features about it that make it worth considering as both a typical and atypical representation of a city.

Spencer's New York chapter begins by discussing the “ecosystem” behind Jay-Z and Alicia Keys's iconic New York song, Empire State of Mind remarking that a “tense mix of survivalist bravado and creative inspiration that defines a place both celebrated and reviled.” It describes how New York for a time became synonymous with decay and violence. New York is also the city that “comes to mind in the context of globalization and urbanization.” However, the author points out that other cities long ago exceeded the growth of New York, and it is the "culture of urbanity,” more than anything else that keeps new York at the fore. “What today looks like a dynamic, exciting and timeless city has not always been so.” It remarks “digging deeper down into the mechanics of how this urban culture and identity function will reveal that a more universal set of characteristics underlies each of the unique cities in the global ecosystem, making them edgy and familiar, exciting, yet safe.”

New York is a city to which other are compared, when it is in fact, quite young. It has changed rapidly, and in the years following 9/11, “global and domestic shocks literally changed the face” of cities such as New York, where “concrete barricades, security gates, and bulletproof glass” popped up throughout the city, something that became refered to as fortress architecture,” while “smart city” tech allowed for remote monitoring of public spaces. Spencer poses that this created a “physically and psychologically damaged” city but also a “softer, more understanding one.”

Despite this daunting architectural shift, New York City continues to attract people and jobs with the "cultural attributes made possible by demographic and economic growth.” Spencer posits that the “secret to this ongoing vibrancy is a unique and attractive identity that permeates deeper than any physical attribute.” Yet New York is a city that is sweltering in the summer while bitterly cold and overcast in the winter months. It has other disadvantages. Spencer points out it is not as attractive as Boston or Washington. However, Spencer comments it is a city which somehow “resolves its own very material problems compared to other large megacities.” A very interesting example of this are the transit strikes in New York, which resolved in only a few days, while in cities like LA transit strikes were rocked by transit strikes that failed to be resolved for weeks. The author neatly surmises the difference: “Wall street executives take the bus from time to time...Hollywood executives don't.”

In the way that New York residents often bump shoulders with various social classes and find themselves crowded together with a range of talents, skills and economic backgrounds, it is also distinctly filled with people familiar with urban politics. These "shared infrastructures and spaces" have pressed together "diverse residents to confront and negotiate with one another on an hourly basis.” In other words, having to “hash out” their difference has made New Yorkers distictly resilient in living together “socially and politically” in a way that more spawling locations such as LA have not. This chapter also describes in detail the challenges of New Yorkers, in particular the history of the epic debates between Jane Jacobs and Robert Moses. It describes the damages and the benefits reaped by "Moses-built environments" something the city still copes with to this day. The last section of the chapter, "Immortality Through Reinvention," describes how Alicia Keys reinvented the song "Empire State of Mind" with her own lyrics, less explicitly celebratory, but more real than the first. Spencer describes recent examples of communities that were considered high-poverty and high-crime that have positively reversed their fortunes. He remarks that New York remains a city for all time, surviving, even thriving, against all odds, a strength derived from the cultural richness of diverse peoples dwelling together for many generations, which has allowed for the unique capacity of New Yorkers to address their political problems with original and compellingly human solutions.

The last chapter, The Global Ecosystem: A Globally Integrated Ecology of Everyday Lifereviews how ecosystem science has been a valuable tool in helping us better see the complex physical environments that create each setting in which gobalization is unfolding. Spencer's book reminds us that no city is truly "the global city" but each one has deeply-rooted and distinct characters and challenges, and that economics is only one function of many functions in a city. Contemporary relationships which strwngthen the unique character and the health of the poor in any city are the measure of worth in globalization, and those that impose are not. Urban planning "best practices" may do well to reframe their thinking as "informative practices," or "suggestive practices," as standardization wastes public resources and is not a path forward for any city. Much more powerful is the ecosystem lens, which helps us coherently understand the building blocks of cities, and how the fundamental differences allows each place to flourish in its own way. Leadership that is "creative, inspired by the human condition, but anchored to earth by realism" allows for the building of cities that thrive without interference, cities, concludes Spencer, that are "about both poetry and engineering.”

Planting Green Roofs and Living Walls: Reduce Water Runoff - Offset Carbon Emissions - Increase Biodiversity- Create Beauty

The authors are experts not only in the construction of green roofs, but on the history of the green roof movement, and have detailed its progress from the early days to contemporary times well. Nigel Dunnett and Noël Kingsbury have revised this book from an earlier edition, adding over 80 new pages. The result is a very authoritative tome on every aspect of green roof and wall creation.

The introduction spends a number of pages looking at different countries and discussing the policies and green roof advances in each of these places. There are many technical details in the book, enough to easily create small scale projects using only the information inside.

Green roofs are becoming an increasingly common sight, on innovative new buildings, on buildings with pre-existing design challenges and very frequently on commercial buildings with flat roofs. Many roofs are prepared as a habitat for local vegetation, and are not intended to grow any species other than those found naturally in the local flora. Still others have wetlands built into them, and become a familiar place for birds to land and nest upon.

Planting on roofs and walls is becoming a discipline of its own in the realm of ecology, as it creates a complex system of habitat for many creatures wherever it is constructed.

This book is beautiful and has a colour photograph on almost every page while most have two or three. For anyone new to the topic, discussions about retrofits required for supporting different types of roofs and networks, planting and watering systems, run-off questions and the integration of living roofs and walls into new buildings are all within these pages. The book was originally listed as a gardening book, but is now listed as architecture. It is a mix of both those disciplines, as well as a strong connection to urban ecology, and a discipline in its own right.

There are now many identifiable hybrid types of roof greening, as buildings are being created to support elaborate green roofs while others are merely adapted, some being extensively greened while others only contain a few green areas. Those green roofs involving high-input garden technique have been covered by several books, while this book is more interested in introducing these low-input roofs and their accompanying living walls.

Bioengineering is a term which describes constructing walls with the intention of integrating planting. Chapter 2, titled Why Build Green Roofs, explores in-depth the environmental benefits of green roofs, or bioengineering in action, including such positive spin-offs as increased biodiversity, which is also represented in graphs. Run-off and roof types are also represented, as are the benefits of green roofs regarding air pollution and carbon sequestration.

It is clear green roofs radically diminish the urban heat island effect as well, provided the buildings are sufficiently irrigated with a source such as recycled rainwater irrigation. The authors cite one particularly interesting study involving a hypothetical green roof coverage of 50% for Toronto's "downtown heat island," a study which found irrigated green roofs reduced the heat effect by a whopping 2 degrees, while unirrigated roofs were discovered to be of far less benefit but still created cooling. Information about recycling and irrigating roofs dispels the suggestion that green roofs and rooftop gardens become water intensive. Other analysis included noise reduction as a positive compliment, and the discovery that solar panels increase an uptick in effectiveness when placed on green roofs, as "the output of (photovoltaic) cells is higher at lower temperatures." The analysis also found that there has been insufficient effort in truly promoting green roofs at a city scale, despite multiple and even cost-offsetting benefits.

Chapter 3, titled Constructing Green Roofs, explores the almost limitless possibilities for construction, and forever dispels the idea that a flat roof is a requirement. The challenges of wind, types of irrigation, and concerns of fire risks are also discussed. Adding one of the better myth-busting facts, while thatched roofs are for instance a fire risk, a green roof is actually the opposite of a fire risk. There are no known green roofs fires in Germany, where there are millions of square feet of green roofs.

Green roof structural requirements are discussed and include underlying structural supports, a green roof deck, a vapour control barrier, and a "waterproofing layer or membrane." Additional covering protects this membrane brilliantly. Green roof materials are explored as methods of planting, growing medium, soils, soil depths and types of systems. The materials section Components of a Green Roof includes several excellent case studies with interesting photos and excellent designs explaining plant combinations for various purposes.

The second half of the book is dedicated to facade greening, the fine art of planting on walls. This was the section that interested me the most. This section begins with a discussion of climbers, something which humans have used for ages but only recently studied. Climber vines often require very little encouragement where there is brick, but a much more dense facade can be made using lightweight steel trellis panels and coconut fiber, as one example, which allows a mix of plants that establish quickly and penetrate the panels well. Different types of trellis such as grids and steel cables are designed for different plants, for instance bougainvillia has adorned buildings for millenia and loves a widely spaced grid. Steel ropes as well as glass fiber are materials which are durable enough to support plants on walls. The authors write, "for heights greater than two stories, choosing supports for climbers and their installation moves into an engineering rather than horticultural territory." However, the book does move into this territory, and I noticed that the earlier version of the book was listed as a gardening book, while this newer edition is listed online as on the topic of architecture. The book encourages plant facade builders to carefully consider design factors, aesthetics, and whether the plants need horizontal as well as vertical supports. As well the book adresess the condition of the wall receiving load bearing fixings, and various tensioning methods.

The authors then proceed to a number of incredibly beautiful case studies, where their limitations and challenges are analyzed in detail. One of the keys to success in creating a living wall is a constant source of water and nutrients to the plants. As the book remarks, "some extremely varied and visually attractive plant communities can be found growing on cliffs where there is a sufficiently constant supply of nutrient-laden water flowing over and down the rock surface. Often these plant communities are highly distinctive, frequently offering refugia for locally rare or highly specialized species. In the temperate zone, some of the best known are the 'coastal bluff' communities of cliff and canyon walls in the Cascade range in north-west North America." Natural hydroponics are occurring when nutrient-rich water trickles down cliff walls from decaying material above. Recreating this through an irrigation system is key to success. The book reinforces to us that green roof runoff is more than merely "a useful resource" and is nutrient dense water that belongs in an integrated plan. Water from roof run off, for example, can be used to irrigate wall plantings to a very positive effect.

The rest of the book is an extensive list of some of the best and most appropriate species for wall and roof gardening. It is an extensive plant directory including plant height and drought tolerance among other details and makes the rest of the book extra indispensable. I wished the book had a bit more detail about food that can be grown on roofs and walls, but the emphasis was a bit more on creating habitat, on reducing urban heat issues and on aesthetics, something the authors acknowledge at the introduction. I recommend this book strongly to anyone interested in green roofs and walls, not as a read but as a permanent fixture to their library.

Urban Biodiversity: From Research to Practice

This is a comprehensive volume edited by Alessandro Ossola and Jari Niemalä, packed with interesting essays from an array of leading researchers. There are forty contributors in all, including, in the tradition of all great edited essay compilations, several essays by the editors themselves. The book contains contributions from universities all over the globe, and include contributors from places as far-flung as Norway, Chile, Australia and South Africa.

The book is designed to underscore the extent of the research that is happening worldwide. Now that researchers have embraced urban biodiversity as a science, "its vast richness" and the importance of urban biodiversity "for the ecological functioning of cities" as well and innate value of urban species biodiversity for citydwellers, has created more research activity in the field than ever before.

The first essay, a collaboration with the editors and researchers, displays a chart with a rise in the numbers of papers published today containing the words "urban," "animals" "plants" and "biodiversity" in the same piece. It remarks that because of this new spike in research activity, cities are able to derive exciting new data. As a result, these new and more detailed studies cause cities to implement action policies, ensuring that urban biodiversity research does connect to real life practice and change.

The next essay discusses urban soil questions and soil management with many illustrations. The illustrations help describe the natural diversity of soil conditions found in urban settings, and highlights a trend where cities often need better functioning biota.

Chapter six, titled Urban Biological Invasion: When Vertebrates Come to Town was a chapter I found particularly interesting. This essay examined the role of mice and rats historically, the problem of grey squirrel invasions in Europe, and looked at a number of other species invasion trends. The essay presented various concerns as well as offering quite a number of solutions, and in general contained a lot of information in a short piece that was well-composed.

Chapter eight addresses biodiversity and social values and preferences, something that is rarely considered. It seems the public often prefers certain species of urban wildlife over others, and the interconnectedness of species is easily forgotten. The essay discussed challenging these perceptions and preferences, guided by awareness campaigns and integrating social sciences. To address biases that lean in favour of some urban wildlife above others, campaigns are built to encourage conservation appreciation in the broader public.

Chapter nine carries on with the examination of human roles in more depth, addressing biodiversity and psychological well-being. The essay asks how to deliver ecosystem services to people. The essay links biodiversity and wellbeing, presents stress reduction theory and highlights the way that biodiversity evokes an automatic positive effect. In reading this chapter I felt as if they were somewhat using the word "biodiversity" where nature might have simply sufficed in the past. However, it was done well and the intentions were of the highest. The authors also described strategies for enhancing a sense cultural good in cities while ensuring higher wild species diversity longterm. To imprint upon the public imagination the concept that "nature" requires "biodiversity" and that enhanced environmental literacy is worthwhile is an on-going effort that seems to be garnering results. The author also cites studies in this chapter, talking about the restorative emotional effects of biodiversity. Inviting more research, they also highlight gaps in information around biodiversity and its impact on public wellbeing, a topic requiring further study.

The final chapter, Urban Green Spaces: An African Perspective, was especially insightful. The chapter claims there are two ideologies at play in some parts of Africa, one derived from South African studies and universities, and those that intuitively develop close to the immediate bioregion in question. For creating biodiversity-friendly cities, conservation and ecological services, attention is required. The essay emphasizes that active citizen engagement is key, as well as some public acknowledgement that urban ecological studies in Africa still show a clear bias towards South African cities. The essay argues that bias has led planmers to overlook different management practices that might be quite essential for the success of services in places with requirements distinct from the South African model. The authors propose urban green spaces be integrated into the urban green infrastructure in a way that is planned and co-managed by all stakeholders...where both people and nature win."

There were quite a few more excellent essays in this small book and I really enjoyed all of them. The research was well-conducted and extremely well referenced. These are essays by scientists all over the world devoted to taking quite a grassroots approach to urban biodiversity. Their inclusion of so much input from social justice concerns was very encouraging. This book is a must-read for anyone interested in the health of the cities in which they live.

Design Like You Give a Damn (2): Building from the Ground Up

This photography-dense 335 page follow-up to the earlier book of the same name is a punchy and unforgettable read. Edited by Architecture for Humanity, the book speaks to architects, designers and artists like myself who want to build projects, desings and installations sustainably, placing community at the fore. There are literally hundreds of inspiring case examples inside this book, all of them full of life and optimism.

The book is divided into sections, the first introductory section in light green addressing "lessons learned." All of the "lesson learned" examples represent projects that have been done in communities, in particular disaster recovery sites, which involve a team, an implementing agency and sponsors, a number of cases this being Architecture for Humanity, but many are the sustainablity projects of architectural firms and architectural schools as well. These teams represent variations of project management coordinators, design fellows, the actual designers, consultants, volunteers, a loan fund and numerous beneficiaries all working behind the scenes to bring a project to life.

Each section looks at various sustainability architecture gems, and examine many astounding case studies. The book is loaded with beautiful photographs that shine with excitement and hope.

Housing is the third section, underscored by the book's designers with forest green accents throughout. it is another exciting array of architectural design projects built to bring out the best in people and alleviate poverty in a sustainable way. The detail and effort that goes into each of these projects is evident, as these architects are trying to bring communities together and create positive living experiences and are somewhat competitive in meeting the challenge. Obviously the themes overlap.

The next and largest section is themed Community, but the efforts of the different architectural design teams in the Housing section now put Community under a high focus lens. There are also some very famous examples in the Community section, in particular the success story of the Highline in New York, The bridge school in China, and the Gimnasio Vertical in Venezuela with 15,000 users monthly. There are, however, many more examples in this largest section, all of them fascinating.

The slender section Basic Services and Materials follows, and these are shown in an installation place but have hundreds to thousands of version as they are designed for function, not architecture per say. Among these is the Emergency Water Bladder, a device developed in 1990 and still in use while being finessed, it is a life-saving way of storing potable water, and these bladders are used by Oxfam to serve thousands of people every day. It also has a section on ecological concrete additives, including the smog-eating concrete developed by a producer in Italy and used to design a church. Smog-eating concrete is infused with titanium dioxide and can trap and neutralize air pollution. Many photos showing the different concepts in action make this an interesting section.

The Politics, Policy and Planning section is almost as big as the Communities section and is the second last section in the book. It focuses on issues including paint and graffiti with fascinating statistics and maps, including where food deserts are most prevalent, how much the expense of removing costs taxpayers (Billions!) and how violence can be prevented through design. This section is as inspiring as the rest of the book, and is followed by the final Reference section, which is dense with information and links.

This book is like an entire course in gritty urban design in one book, with gorgeous photos and an energy that is super upbeat. I highly recommend it and I'm glad I read it. It provides excellent perspective and profoud inspiration to artists and designers, and I look forward to Design Like You Give a Damn 3.

Design Ecologies: Essays on the Nature of Design

Edited by Lisa Tilder and Beth Blostein, this interesting book has twenty contributors comprising 16 essays and grew out of a symposium of the same name. The editors state that they have set out to explore how "ecological design" operates "synergistically across design disciplines." Blostein explain that while, "the nineteenth-century German biologist Ernst Haeckel defined ecology as 'the comprehensive science of the relationship of the organism to the environment,' they would go further and add, 'in which each living organism has an ongoing and continual relationship with all elements."

In the first essay, designer Bruce Mau describes his team's Massive Change project. The Massive Change project was a series of installations that was originally curated by the Vancouver Art Gallery as a project on the future of design. The show was such a controversial success thst they then toured. Mau remarks, "conditioned by an apocalyptic future, people lose their ability to imagine a future. They become self-interested. The most insidious by-product of this doomsday thinking is apathy." Mau states that "a project which sees the welfare of all life," and promotes Stewart Brand's "enlightened self-interest" thesis, is a path of "informed optimism" as well as information sharing and new solutions.

The next essay, by designer Cameron Tonkinwise, poses the question, "if we designed our way into unsustainability...do we have to design our way out of it...or do we desperately need new, other-than-designing ways of responding to these large-scale problems?" Tonkinwise suggests perhaps either argument is too stark. He asks, "can we redesign designing?"

In his essay, Weeding the City of Unsustainable Cooling, Tonkinwise writes a detailed and lucid examination of the unenvironmental window air conditioner issue in New York, and the impossibility of demolishing everywhere that requires them. Tonkinwise asks, "so what would it take to accomplish the task of quickly removing window box air conditioners from New York?" Reminding us that early New Yorkers sweltered often without complaint and that air conditioners may have 'conditioned' humans to a false reality of what is normal in summer, he acknowledges that some people cannot live without air-con, and it would be ableist to assume otherwise. Likening a.c. boxes to a weed species, Tonkinwise asseses the massive "artificial dependencies" that they represent, and poses that the cooling of urban buildings must then be seen as "a constellation of colliding desires." The task must not become "a determination of the minimum atmospheric conditions necessary for existence as a requirement for totally rebuilt sustainable cities," says Tonkinwise. Instead, he calls for a pressing need to change and to create "new desires, not less desire." He concludes that only "reversible moves" avoid designs that do not arrogantly scrap everything in the hope of getting it right.

I found the essays in this book intriguing and provocative, with a range of discussions and intense examinations of both materials and the historic excesses of design as well as the worthiness of excess in certain contexts.

In "Green Screens: Modernism Secret Garden," essayists Robert Sumrell and Kazys Varnelis shine a hard light on green design. Evoking the previously under-examined social role of the fern bar, which was a windowless space popular in earlier decades where singles could meet, they point out that singles were also emboldened to connect in an atmosphere where a collection of indoor ferns were actually slowly dying. "The fern acts as a mediator of the impersonality of modern life...as something between the living and an object." Remarks the essayists, "as an early moment of ecological architecture, the fern bar makes the moral duplicity of green design apparent...But in giving themselves up, the ferns allowed their patrons to do what they really wanted, to seek self-gratification. The green movement today allows us this too...ratcheting up consumption, green design makes the world our fern bar."

The level of examination evident in the "fern bar" piece is typicsl of the essays in this book. Stylish and also at times vexing, it wasn't quite what I expected from writers critiquing the aims of their profession. The rest of the essays however are also like this, relentless and eloquent examinations of architecture and its role.

In the final essay, titled Towards a Productive Excess, author and editor Beth Blostein examines the days when architecture and power stations came together to create monumental designs celebrating the "glory" of energy production. In promoting new beginnings, Blostein proposes, "nothing short of a renewed architectural exuberance is required." Citing the example of energy-generating buildings that invite a new kind of city, she asks us to imagine the emergence of a "model of energy as an ever-convertible, fluid asset." Blostein couples this with her interest in movable and pre-assembled structures. She suggests we consider "HOK's stadium for the 2021 London Olympics," which was deliberately designed to be disassembled "after the games, and rebuilt for the next Olympic hopeful, Chicago." Says Blostein, "as a large-scale endeavor, this exuberant, pervasive energy production will allow contemporary culture and its technological needs to thrive and develop, and allow a place again for the delights of excess."
