Urban Ecology Reading List 2: Landscape Ecology

URBAN ECOLOGY READING LIST – 2

Beyond some of the specific books focusing  on the science of Urban Ecology, there are subsets of literature that support this study.  This is the first of three posts to expand the reading list that investigate these other, related disciplinary alignments, including landscape ecology, the hybrid books on planning and design based on ecological systems, and finally, a set of formative literature on environmental planning & design I would consider part of the historical canon.

Landscape Ecology

Closely linked is the science of landscape ecology, which according to the International Association for Landscape Ecology is “…the study of spatial variation in landscapes at a variety of scales. It includes the biophysical and societal causes and consequences of landscape heterogeneity. Above all, it is broadly interdisciplinary.  
The conceptual and theoretical core of landscape ecology links natural sciences with related human disciplines. Landscape ecology can be portrayed by several of its core themes, including the spatial pattern or structure of landscapes, ranging from wilderness to cities, the relationship between pattern and process in landscapes, the relationship of human activity to landscape pattern, process and change, [and] the effect of scale and disturbance on the landscape.”

 


Foundation Papers in Landscape Ecology   Moss, Turner, Mladenoff, Weins (eds).  Columbia University Press, November 2006.

Landscape ecology focuses on spatial heterogeneity, or the idea that where things are and where they are in relation to other things can have important consequences for a wide range of phenomena. Landscape ecology integrates humans with natural ecosystems and brings a spatial perspective to such fields as natural resource management, conservation, and urban planning. The thirty-seven papers included in this volume present the origins and development of landscape ecology and encompass a variety of perspectives, approaches, and geographies. The editors begin with articles that illuminate the discipline’s diverse scientific foundations, such as L. S. Berg’s keystone paper outlining a geoecological analysis based on soil science, physical geography, and geology. Next they include selections exemplifying landscape ecologists’ growing awareness of spatial pattern, the different ways they incorporated scale into their work, the progression of landscape ecology from a qualitative to a quantitative discipline, and how concepts from landscape ecology have come to permeate ecological research and influence land-use policy, conservation practices, landscape architecture, and geography. Together these articles provide a solid introduction to what is now widely recognized as an important area of research and application that encourages new ways of thinking about natural and human-dominated ecosystems


Landscape Ecology, 1st ed.   Richard T.T. Forman & Michel Godron.  Wiley, February 1986.

This important new work–the first of its kind–focuses on the distribution patterns of landscape elements or ecosystems; the flows of animals, plants, energy, mineral nutrients and water; and the ecological changes in the landscape over time. Includes over 1,200 references from current ecology, geography, forestry, and wildlife biology literature.

 

 


Landscape Ecology in Theory and Practice: Pattern and Process, 2nd ed.   Monica G. Turner & Robert H. Gardner, Springer, November 2015  [original publication date 2003]

This work provides in-depth analysis of the origins of landscape ecology and its close alignment with the understanding of scale, the causes of landscape pattern, and the interactions of spatial pattern with a variety of ecological processes. The text covers the quantitative approaches that are applied widely in landscape studies, with emphasis on their appropriate use and interpretation.

The field of landscape ecology has grown rapidly during this period, its concepts and methods have matured, and the published literature has increased exponentially. Landscape research has enhanced understanding of the causes and consequences of spatial heterogeneity and how these vary with scale, and they have influenced the management of natural and human-dominated landscapes. Landscape ecology is now considered mainstream, and the approaches are widely used in many branches of ecology and are applied not only in terrestrial settings but also in aquatic and marine systems. In response to these rapid developments, an updated edition of Landscape Ecology in Theory and Practice provides a synthetic overview of landscape ecology, including its development, the methods and techniques that are employed, the major questions addressed, and the insights that have been gained.”


Landscape Ecology: Theory and Application, 2nd ed.  Zev Naveh & Arthur S. Lieberman, Springer, December 1993.

In the preface to the softcover edition of this book in 1989, we stated: Since the publication of the first edition of this book, landscape ecology has made great strides. It has overcome its continental isolation and has also established itself in the English-speaking world. By attracting both problem inquiry and problem-solving-oriented scientists with different cultural, academic, and profes­ sional backgrounds from all over the world, it has broadened not only its geo­ graphical but also its conceptual and methodological scopes. We are pleased to confirm in 1993 that the growth of landscape ecology continues, and to again express our gratification at the encouraging re­ sponse to this first English-language monograph on the subject and its contribution to these developments. As before, we feel special satisfac­ tion that it has reached not only the shelves of libraries and academic re­ searchers, but that it has also appealed to professional practitioners, teachers, and their students from industrialized and developing countries, embracing the broad range of fields related to landscape ecology in the natural sciences as well as in the humanities.


Land Mosaics: The ecology of landscapes and regions, 1st edition.  Richard T.T. Forman.  Cambridge Univ. Press, November 1995.

Animals, water, wind, and people flow at different rates according to spatial patterns common to almost all landscapes and regions. This up-to-date synthesis explores the ecology of heterogeneous land areas, where natural processes and human activities interact to produce an ever changing mosaic. The subject has great relevance to contemporary society and this book reflects the breadth of this importance: there are many ideas and applications for planning, conservation, design, management, sustainability and policy. Spatial solutions are provided for society’s land-use objectives. Students and professionals alike will be drawn by the attractive and informative illustrations, the conceptual synthesis, the wide international perspective, and the range of topics and research covered.


Learning Landscape Ecology: A Practical Guide to Concepts and Techniques, 2nd ed.  Sarah E. Gergel & Monica G. Turner (eds).  Springer, April 2017.

This title meets a great demand for training in spatial analysis tools accessible to a wide audience. Landscape ecology continues to grow as an exciting discipline with much to offer for solving pressing and emerging problems in environmental science. Much of the strength of landscape ecology lies in its ability to address challenges over large areas, over spatial and temporal scales at which decision-making often occurs. As the world tackles issues related to sustainability and global change, the need for this broad perspective has only increased. Furthermore, spatial data and spatial analysis (core methods in landscape ecology) are critical for analyzing land-cover changes world-wide. While spatial dynamics have long been fundamental to terrestrial conservation strategies, land management and reserve design, mapping and spatial themes are increasingly recognized as important for ecosystem management in aquatic, coastal and marine systems.

This second edition is purposefully more applied and international in its examples, approaches, perspectives and contributors. It includes new advances in quantifying landscape structure and connectivity (such as graph theory), as well as labs that incorporate the latest scientific understanding of ecosystem services, resilience, social-ecological landscapes, and even seascapes. Of course, as before, the exercises emphasize easy-to-use, widely available software.


Urban Landscape Ecology: Science, policy and practice (Routledge Studies in Urban Ecology)  Robert A. Francis, James D.A. Millington, Michael A. Chadwick (editors), Routledge, April 2016

The growth of cities poses ever-increasing challenges for the natural environment on which they impact and depend, not only within their boundaries but also in surrounding peri-urban areas. Landscape ecology – the study of interactions across space and time between the structure and function of physical, biological and cultural components of landscapes – has a pivotal role to play in identifying sustainable solutions.  This book brings together examples of research at the cutting edge of urban landscape ecology across multiple contexts that investigate the state, maintenance and restoration of healthy and functional natural environments across urban and peri-urban landscapes. An explicit focus is on urban landscapes in contrast to other books which have considered urban ecosystems and ecology without specific focus on spatial connections. It integrates research and perspectives from across academia, public and private practitioners of urban conservation, planning and design. It provides a much needed summary of current thinking on how urban landscapes can provide the foundation of sustained economic growth, prospering communities and personal well-being.

Urban Ecology Reading List – Updated

Note:  This was originally published in late June, with a plan to include specific books that discussed the science of urban ecology.  I’ve added a few titles in this realm to the original post on 7/7 and organized them alphabetically with a summary at the beginning.

The literature of the somewhat youthful discipline of urban ecology contains a relatively small number of books, at least for now.  I’m compiling resources on a number of topics, starting with specific topics of Urban Ecology, but will be adding more on some related ideas such as Landscape Ecology, Ecological Urbanism, as well as more historical titles from the Design Canon.  This initial list below is a start, with some summaries for a bit of context.

If you know of others to add let me know!

URBAN ECOLOGY


Advances in Urban Ecology: Integrating Humans and Ecological Processes in Urban Ecosystems   Marina Alberti, Springer, December 2008.


The future of Earth’s ecosystems is increasingly influenced by the pace and patterns of urbanization. One of the greatest challenges for natural and social scientists is to understand how urbanizing regions evolve through the complex interactions between humans and ecological processes. Questions and methods of inquiry specific to our traditional disciplinary domains yield partial views that reflect different epistemologies and understandings of the world. In order to achieve the level of synthesis required to see the urban ecosystem as a whole we must change the way we pose questions and search for answers.

Cities are the result of human and ecological processes occurring simultaneously in time and in space and the legacy of the simultaneous processes of the past. Urban ecology is the study of the co-evolution of human-ecological systems. Scholars of both urban systems and ecology must challenge the assumptions and world views within their disciplines and work towards a hybrid theory that builds on multiple world views.

The synthesis of research findings provided in this book is a first step towards articulating the challenge for scholars of urban ecosystems; it leads the way toward the integration we must achieve if we are to better understand and solve emerging issues in urban ecosystems.


Ecology of Urban Environments, Kirsten M. Paris.  Wiley-Blackwell, May 2016.

 Urban environments are expanding globally as the number and proportion of humans that live in cities continues to increase. The discipline of urban ecology is also expanding as interest surges in the ecological impacts of urbanization and the diverse ways in which urban environments can affect their human and non-human residents.

This book provides an accessible introduction to urban ecology, using established ecological theory to identify generalities in the complexity of urban environments. Engaging yet scholarly, it examines the biophysical processes of urbanization and how these work together to influence (a) the characteristics of urban environments in developed and developing countries, and (b) the dynamics of urban populations, communities and ecosystems. With a strong international focus, it also explores the ecology of humans in cities and discusses practical strategies for conserving biodiveristy and maintaining ecosystem services in urban environments. Finally, it argues that existing ecological theory is appropriate for understanding the ecology of urban environments across all levels of organization, from individual organisms to entire ecosystems; effective science and management need not wait on a new theory of urban ecology.


The Routledge Handbook of Urban Ecology, Ian Douglas, David Goode, Mike Houck, Rusong Wang.  Routledge, March 2015.

The birds, animals, insects, trees and plants encountered by the majority of the world’s people are those that survive in, adapt to, or are introduced to, urban areas. Some of these organisms give great pleasure; others invade, colonise and occupy neglected and hidden areas such as derelict land and sewers. Urban areas have a high biodiversity and nature within cities provides many ecosystem services including cooling the urban area, reducing urban flood risk, filtering pollutants, supplying food, and providing accessible recreation. Yet, protecting urban nature faces competition from other urban land uses.

The Handbook of Urban Ecology analyses this biodiversity and complexity and provides the science to guide policy and management to make cities more attractive, more enjoyable, and better for our own health and that of the planet. This Handbook contains 50 interdisciplinary contributions from leading academics and practitioners from across the world to provide an in-depth coverage of the main elements of practical urban ecology. It is divided into six parts, dealing with the philosophies, concepts and history of urban ecology; followed by consideration of the biophysical character of the urban environment and the diverse habitats found within it. It then examines human relationships with urban nature, the health, economic and environmental benefits of urban ecology before discussing the methods used in urban ecology and ways of putting the science into practice.

The Handbook offers a state-of the art guide to the science, practice and value of urban ecology. The engaging contributions provide students and practitioners with the wealth of interdisciplinary information needed to manage the biota and green landscapes in urban areas.


Urban Ecology: An Introduction, 1st edition.  Ian Douglas & Philip James.  Routledge, January 2015.

Urban Ecology: An Introduction seeks to open the reader’s mind and eyes to the way in which nature permeates everyday urban living, and how it has to be understood, cared for, and managed in order to make our towns and cities healthier places to visit and in which to live and work. The authors examine how nature can improve our physical and mental health, the air we breathe and the waters we use, as well as boosting our enjoyment of parks and gardens. Urban Ecology sets out the science that underlies the changing natural scene and the tools used to ensure that cities become both capable of adapting to climate change and more beautiful and resilient.

The book begins with a discussion of the nature of urban places and the role of nature in towns and cities. Part 1 looks at the context and content of urban ecology, its relationship to other foci of interest within ecology and other environmental sciences, and the character of city landscapes and ecosystems. In Part 2 the authors set out the physical and chemical components of urban ecosystems and ecological processes, including urban weather and climate, urban geomorphology and soils, urban hydrology and urban biogeochemical cycles. In Part 3 urban habitats, urban flora and fauna, and the effects of, deliberate and inadvertent human action on urban biota are examined. Part 4 contains an exploration of the identification and assessment of ecosystem services in urban areas, emphasising economic evaluation, the importance of urban nature for human health and well-being, and restoration ecology and creative conservation. Finally, in Part 5 the tasks for urban ecologists in optimising and sustaining urban ecosystems, providing for nature in cities, adapting to climate change and in developing the urban future in a more sustainable manner are set out.


Urban Ecology (Ecological Reviews), Kevin J. Gaston (editor).  Routledge, March 2015.
This is the urban century in which, for the first time, the majority of people live in towns and cities. Understanding how people influence, and are influenced by, the ‘green’ component of these environments is therefore of enormous significance. Providing an overview of the essentials of urban ecology, the book begins by covering the vital background concepts of the urbanisation process and the effect that it can have on ecosystem functions and services. Later sections are devoted to examining how species respond to urbanisation, the many facets of human-ecology interactions, and the issues surrounding urban planning and the provision of urban green spaces. Drawing on examples from urban settlements around the world, it highlights the progress to date in this burgeoning field, as well as the challenges that lie ahead.


Urban Ecology: Patterns, Processes, and Applications, Niemela, Breuste, Guntenspergen, MyIntyre, Elmqvist, and James.  Oxford University Press, January 2012.


Urbanization is a global phenomenon that is increasingly challenging human society. It is therefore crucially important to ensure that the relentless expansion of cities and towns proceeds sustainably. Urban ecology, the interdisciplinary study of ecological patterns and processes in towns and cities, is a rapidly developing field that can provide a scientific basis for the informed decision-making and planning needed to create both viable and sustainable cities.

Urban Ecology brings together an international team of leading scientists to discuss our current understanding of all aspects of urban environments, from the biology of the organisms that inhabit them to the diversity of ecosystem services and human social issues encountered within urban landscapes. The book is divided into five sections with the first describing the physical urban environment. Subsequent sections examine ecological patterns and processes within the urban setting, followed by the integration of ecology with social issues. The book concludes with a discussion of the applications of urban ecology to land-use planning. The emphasis throughout is on what we actually know (as well as what we should know) about the complexities of social-ecological systems in urban areas, in order to develop urban ecology as a rigorous scientific discipline.


Urban Ecology: Science of Cities, 1st edition.  Richard T.T. Forman.  Cambridge Univ. Press, April 2014.

How does nature work in our human-created city, suburb, and exurb/peri-urb? Indeed how is ecology – including its urban water, soil, air, plant, and animal foundations – spatially entwined with this great human enterprise? And how can we improve urban areas for both nature and people? Urban Ecology: Science of Cities explores the entire urban area: from streets, lawns, and parks to riversides, sewer systems, and industrial sites. The book presents models, patterns, and examples from hundreds of cities worldwide. Numerous illustrations enrich the presentation. Cities are analyzed, not as ecologically bad or good, but as places with concentrated rather than dispersed people. Urban ecology principles, traditionally adapted from natural-area ecology, now increasingly emerge from the distinctive features of cities. Spatial patterns and flows, linking organisms, built structures, and the physical environment highlight a treasure chest of useful principles. This pioneering interdisciplinary book opens up frontiers of insight, as a valuable source and text for undergraduates, graduates, researchers, professionals, and others with a thirst for solutions to growing urban problems.


Urban Ecology: Strategies for Green Infrastructure and Land Use, Kimberly Etingoff, Apple Academic Press, July 2015

 With increasing global urbanization, the environments and ecologies of cities are often perceived to suffer. While pollution and destruction of green space and species may occur, cities also remain part of natural systems. Cities provide natural processes necessary for survival for humans and other living organisms in urban areas. Urban ecology elucidates some of these processes and sheds light on their importance to healthy, fulfilling urban livelihoods.

Urban Ecology: Strategies for Green Infrastructure and Land Use provides background on issues relating to urban ecology and urban natural processes. The first section covers the types, values, and recognition of ecosystem services provided by natural processes in urban areas. The second section details the importance and potential of green spaces in urban areas. The third section focuses on biodiversity traits of cities, and the ways in which urbanization affects biodiversity indicators. Finally, the fourth section covers some of the tools and approaches available for urban planners and designers concerned with improving or maintaining urban environments and the services they provide.

This easily accessible reference volume offers a comprehensive guide to this rapidly growing field. Case studies and up-to-date research provide urban planners with new options for creating cities that will meet the demands of the twenty-first century. Also appropriate for graduate students who are preparing for careers related to urban planning, this compendium captures and integrates the current work being done in this vitally important field.


Urban Ecosystems: Ecological Principles for the Built Environment, 1st edition.  Frederick R. Adler and Colby J. Tanner.  Cambridge Univ. Press, June 2013.

As humans have come to dominate the earth, the ideal of studying and teaching ecology in pristine ecosystems has become impossible to achieve. Our planet is now a mosaic of ecosystems ranging from the relatively undisturbed to the completely built, with the majority of people living in urban environments. This accessible introduction to the principles of urban ecology provides students with the tools they need to understand these increasingly important urban ecosystems. It builds upon the themes of habitat modification and resource use to demonstrate how multiple ecological processes interact in cities and how human activity initiates chains of unpredictable unintended ecological consequences. Broad principles are supported throughout by detailed examples from around the world and a comprehensive list of readings from the primary literature. Questions, exercises and laboratories at the end of each chapter encourage discussion, hands-on study, active learning, and engagement with the world outside the classroom window.

 

 

 

 

 

 

 

Introducing Hidden Hydrology

Regular readers of the blog know of my long-time passions of both Vegitecture and Hidden Hydrology, which both dovetail nicely into the larger themes of Landscape+Urbanism.  While the L+U blog has been relatively intermittent, I’ve been hard at work developing a new website and blog for the Hidden Hydrology project. The goal is to culminate the work in some form of publication, but regardless, it seemed time to focus on that element in it’s own.  I’m also giving a talk at the Washington ASLA conference in Spokane later this month (April 21), so excited to share more to a broader audience.  Simply put, the project is summarized as:

“Exploring lost rivers, buried creeks & disappeared streams. Connecting historic ecology + the modern metropolis.”

1.

Without going into too much detail that may be gained by going to the site itself, the project is broken down into four sections.  The first section gives a quick overview of hidden hydrology and links to some of my original inspirations, including Anne Whiston Spirn and David James Duncan, along with an early, evocative map of Portland, along with the amazing historical ecology around the book Mannahatta.

A bit longer summary gives some context for the endeavor:  “At the basic level, hidden hydrology is the buried, piped and disappeared waterways that flow under our urban areas.  Development has driven underground these surface streams that used to weave through our cities – and with them we’ve lost the connection to natural systems, and robust ecological habitat that urban waterways can provide.  Beyond just focusing on pure daylighting and restoration, the exploration, mapping, and study of hidden hydrology offers new ways to conceptualize a range of interventions that reconnect us to our history and offer glimpses of solutions for the future.  It’s a broader concept of ‘restoration’ that looks through lenses of art, landscape architecture, urban ecology, and planning to define ways to celebrate, connect and regenerate our places.”

2.

The second section are links to many of the resources available, including precedents, projects, and resources from around the globe.  While linking to the other pages, I’m also providing links to some of the posts, including a diverse mix from Rome to London, San Francisco to Lexington, Kentucky.  The range of projects isn’t limited to projects, but encompasses art, mapping, poetry, literature, dance, stream daylighting, films, community engagement, and history.

A couple of highlights, including the project “Ghost Arroyos” in San Francisco:

Or the cool mapping work of David Ramos in DC at Imaginary Terrain.

3.

The third is an ongoing exploration of themes in a more expanded format, the site is built aroud a blog that has delved into some of the resources, and projects, but also allows for some rumination and coverage of original project work.   Of the 25 or so posts to date, many have covered cities and projects, expanding to case studies and deeper investigations.   These include projects inspired by hidden hydrology (such as Town Branch Commons in Lexington, top below), as well as historical maps and photos referenced in a literary context (Iain Sinclair’s ‘Swimming to Heaven’), and more in depth historical ecological studies (San Francisco Estuary Institute) to show a few.

1854 — The Corporation of London workmen repairing the Fleet sewer, south of Fleet street under the direction of Mr. W. Haywood. The sewers carried 87,000,000 gallon of water daily in 1854. — Image by © CORBIS

The diversity is what surprised me, to different tendrils which weave beyond just mapping but into a multitude of subjects.  An early post on the site, is illustrative of this concept, and is still one of my favorites, focused on the novel by Ben H. Winters, Underground Airlines and it’s use of the hidden hydrology of Indianapolis to tell a futuristic narrative of modern day slavery.

An excerpt from the novel explains this in a bit more detail.

“I cleared the trailer park and passed a jumble of picnic benches and playground equipment and stepped carefully down the slope of the ravine and swung the heavy beam of my flashlight along the creek.  Now it was clear, with the water swollen by the rains, the direction the brown water was still flowing.  The black mouth in the base of the shallow hill was an entrance, not an exit.  This low little trickle of mud water was a kind of rivulet, a poor cousin of a creek, and this spot behind the motor court is where some long-ago engineer had diverted it.
The creek was called Pogue’s Run. I’d found it on the map. I’d looked up the story.  This small waterway was discovered at the turn of the century – the eighteenth turning into the nineteenth — discovered and named and recorded, penciled in on early maps, when the city was not yet a city — when it was a gathering of huts, a stopping place on the way to other places.  The small river was inconvenient for the city fathers and the grid they’d drawn.  So they did just as Mama Walker said: they ran it underground.”

Beyond the fringes of hidden hydrology include some diversion into the very cool Atlas of Oblique Maps, a fascinating set of historical climate maps from the 1850s, and the ever popular Fisk maps of the evolution of changes to the Mississippi River.

4.

The fourth, which is more of a long-term is projects, is still in nascent stage, but offers the potential to showcase original work around Hidden Hydrology, specifically in Portland and Seattle, but encompassing some other miscellany as well.  Currently it highlights some early presentations, as well as base-mapping of the Cadastral Survey for each city, the springboard for further analysis.

The Mississippi maps inspired me to use some of the documentations to animate the changing course of the river within the valley over the last 4000 years.  These more

 

There’s a ton of great information out there, yet it’s an area of study that seems relatively untapped and full of potential.  If you’d like to contribute, know of some great case studies, and have the bug for historical maps, and how these can inform ecological design today, give a shout.  In the interim, check out the site and follow @hiddenhydrology on Twitter.

And stay tuned for some more explorations here at L+U related to urban ecology and habitat, and more posts on some recent vegitecture, as I am working on some related projects and doing some more focused research in these realms.

Google Timelapse

The announcement Google Earth Timelapse has created a bit of a stir, with a number of videos exploring landscape change of natural and urban systems.  From their site:

“Timelapse is a global, zoomable video that lets you see how the Earth has changed over the past 32 years. It is made from 33 cloud-free annual mosaics, one for each year from 1984 to 2016, which are made interactively explorable by Carnegie Mellon University CREATE Lab’s Time Machine library, a technology for creating and viewing zoomable and pannable timelapses over space and time.”

I’m a bit disappointed with the resolution – as it is not able to zoom in to a district level at a scale that provides appropriate level of detail.  That may be surmountable by using Google Earth Engine and delving into the API and programming tools.

There’s also a series of Datasets that are available from the Google Earth Engine that would be interesting to explore also, including maps for aerial imagery, geophysical data, climate/weather and demographics.

I used the Timelapse Tour Editor to quickly make a few maps of Seattle and Portland – with an eye towards  For Seattle, I wanted to focus on the development of South Lake Union, where Amazon and other development has been most pronounced in the past decade or so.  It shows how much redevelopment has occurred there, as well as throughout the downtown core (mostly visible with white roofs).

These are better by clicking the title and viewing in full size, as the grain for urban areas is pretty bad. 

South Lake Union and Downtown Seattle

For Portland, I wanted to zoom in on the inner Southeast area, around Division Street, which was been subject to a fair amount of density in recent years.  The inability to zoom into that level of detail makes this a bit less instructive, but does show the level of development north of downtown, and across the river the ‘fingers’ of density on transit mixed-use streets (which is what provides for vibrant, walkable urban neighborhoods that make Portland, well… Portland.

Portland

Lots of fun exploration planned for this.

Water and Cities

Interesting exploration from Architect’s Newspaper from October covering a range of water specific projects and proposals in the urban realm.  A short description:

“For landscape architects today, urbanism and water go hand in hand. Whether dealing with issues of sea level rise, groundwater retention, or just plain old water supply infrastructure, landscape architects are working with scientists, engineers, and policy makers on increasingly bigger projects that encompass more external factors and larger networks of physical, biological, environmental, and political networks. We examine some of these water landscapes and how they relate to each other in the broader context of how resources and climate-related changes are being managed.”

The grid locates these twelve projects in the field, with poles ranging on one axis from Decadence to Survival and on the other pole from Not Enough to Too Much.  It’s a simple diagram that shows the complexity of water and the need for regional and adaptive solutions that address multiple problems but are also specific to place.  This spans climate change, drinking water, development, and ecology — balancing all of the variety of needs for livability, economy and social equity of which water is intertwined.  Check out the post for more detail, but a few highlights worthy of discussion.

1-feature_020an05-645x648

The issue of climate refugees is going to continually be more and more common in the news.  One such example is Shishmaref, Alaska who have “…asking whether it’s better to suffer the slings and arrows of outrageous fortune or take arms against a sea of troubles to combat a looming climate change–driven disaster.”  While consultants have said they should stay, a recent vote went in favor or relocating the town, which is on an island in the Bering Straight, to the safer mainland, and they are looking for the $200 million necessary to do so.

shishmaref

Miami is an example of a much more populated city dealing with climate issue, such as flooding and access to clean drinking water, even when the city continue to grow rapidly. “Miami’s real estate value continues to rise despite the chronic flooding risks on its waterfront. Even as local governments pour millions into tackling high tides and storm surges, deeper economic and infrastructural issues loom as threats to growth and prosperity.”

miami_beach_flood

Another interesting take on flooding, Chicago is looking at underground sand deposits that were built over, and still exist, to provide a unique resilience strategy.  “The challenge is immense—for Chicago, one inch of rainfall equals four billion gallons. Until recently Chicago’s answer to the problem has been an infrastructure project no less than epic—read costly—in scale. But one landscape architect is leading an effort to change how the city can unlock its hidden potential for storm water management”

On the flip side, proposals for water scarcity are happening in Texas, through innovative methods of protecting supply, as well as creating controversy as cities in Wisconsin start asking to draw water from Lake Michigan.

And what review of water would be complete without some discussion of the contentious LA River, (banner image above) which is being tackled by multiple teams and has created some rifts in the design community, particularly that of putting Frank Gehry in charge of the latest public sceme.  One postive from the Gehry team (in addition to including a good mix of other disciplinares) that I’m curious about is the “L.A. River VR Experience, an initiative by media producers Camilla Andersson and Anders Hjemdahl at Pacific Virtual Reality and FoLAR… The project is currently in the final stages of production and features a VR tour along the entire LA River. “

vrla008-645x323

The work of Studio Gang to develop interdisciplinary solutions to ecological projects is interesting, and the work of UrbanLab also provides some context for water projects in China.

urbanlab_yangming-archipelago_04-645x363

Lots more, so check out all of these brief articles and the matrix of abundance and scarcity and decadence and survival is a unique frame to look at water solutions.  Finally, for more in-depth look at one of these projects, check out my post over at Hidden Hydrology to find out more on the Town Branch Commons project by SCAPE and the ‘daylighting’ of an urban waterway in Lexington, Kentucky.

LA+ The Tyranny Issue

I’ve posted previously about the LA+ Journal, which has had previous issues focused on both Wild (reviewed here) and Pleasure in previous issues.  The current issue takes a radically different turn – with a focus on subjects around the broad concept of Tyranny.  Perhaps a strange topic for landscape architecture journal to tackle, and I had that reaction a bit myself, but it quickly became clear that tyranny is a much more radically complex idea than what comes to mind, and the social, economic, and spatial manifestations have direct relevance on urban spaces, their design, and their evolution.

Tyranny-17_600

“From the first utopian impulse of Plato’s Republic to today’s global border controls and public space surveillance systems, there has always been a tyrannical aspect to the organization of society and the regulation of its spaces. Tyranny takes many forms, from the rigid barriers of military zones to the subtle ways in which landscape is used to ‘naturalize’ power. What are these forms and how do they function at different scales, in different cultures, and at different times in history? How are designers and other disciplines complicit in the manifestation of these varying forms of tyranny and how have they been able to subvert such political and ideological structures?

LA+ TYRANNY asked contributors to consider how politics, ideology, and technology manifest in our landscapes and cities in ways that either advance or restrict individual and collective liberty.

Tyranny-21_600

The unique lens of tyranny is understood in recent cultural context early, in the essay ‘Blood on the Square’ by Steve Basson (8).  The concept of the square as free and ‘democratic space’ indicative of the historic connotation of the Greek Agora ‘political debate’ and at times the locus of “heroic protest” as seen in the US and abroad is contrasted with the square as a historical place for terror and exercising of oppression.  Examples of these public spaces being used for public executions, propaganda and military force, as well as new levels of surveillance through CCTV and policing and other means evokes dystopian visions of Bentham’s Panopticon and Orwellian visions of Big Brother.

The space, like any others, is available for both freedom and repression, and that a ‘pure’ public space is a myth.  As referenced by Foucault, the history of the public square as exceptional or positive is built on subjugated knowledge “…where historical contents have been buried or masked in order to preserve the privileged nature of a particular narrative.” (12)  The takeaway is that the square is not purely heroic, but is a ‘contested terrain’ and one that “… is virtuous and democratic but also grim and menacing.(13)  It also means that our power as designers is limited, because it is a dubious assumption that spatial organization could be employed to shape use in certain ways, and thus architecture and design “cannot create freedom in space” but rather from Foucault again:

“I do not think that there is anything functionally, by its very nature, absolutely liberating… the guarantee of freedom is freedom.” (13)

The theme brought up the previous essay is echoed in two subsequent writings.  First, Gandy’s “The Glare of Modernity” (15) explores some of the power dynamic through the tyranny of lighting, which has been employed as a “means of intimidation and control,” and has now become synonymous with ‘safety’ to the detriment of livability and health through ubiquity.  From a political perspective, Chang Tai Hung’s “Tianamen Square: The Grand Political Theater of the Chinese Communist Party” (20) explores the history and spatial configuration of this enormous public space in Beijing. While ostensibly the ‘People’s Square’ the narrative is more relevant to use of propaganda and designed with a focus on spaces not of comfort (no trees, benches) but of immensity and political power, referencing the communist “…contempt for leisure activities of the bourgeois…” while also avoiding the potential for spaces to be “subversive gathering spaces.” (22)  The events there are then not people-driven, but “highly orchestrated” and a spatial equivalent of “a scripted text” (24) where those in power fear the unscripted.

A common theme arises around the activities of the Arab Spring and the Occupy movement where places like Tahrir Square in Cairo, and Zuccotti Park in New York became well known, among many others as significant places of occupation and protest.  Erik Swyngdouw’s exploration in “The Velvet Violence of Insurgent Architects” (27) looks at these places of political protest and the participants as “radical imagineers” of a new urban future that can include spatial policies of planning, architecture, urban design against powers that are averse to disturbance. (28) The concepts around the Right to the City movement (both formal and informal are realized in these “tactics of resistance” (29) and that these insurgent architects become designers of a sort:

“While staging equality in public squares is a vital moment, the process of transformation requires the slow but unstoppable production of new forms of spatialization quilted around materializing the claims of equality, freedom, solidarity.” (30)

Another reference to the Arab Spring is from Mona Abaza’s “Memory and Erasure”, (32) which looks again at Cairo, Egypt but through a different lens of public / political art complementing the occupation of public spaces.  The process of art being used as part of protest, and the subsequent painting over by authorities was a subtext of the larger power struggles happening within spaces throughout the cities.

Rodrigo Jose Firmino explores technology in his essay “Connected and Controlled: Surveillance, Security and Cities” (42) which looks at a more pernicious tyranny that effects most of us.  Expanding on Castells notion of the “informational city” with new technology and the Internet of Things, the essay posits a “Programmable City” where data is not just captured but utilized – taking advantage of the ubiquity and our reliance on smart technology to exert levels of control never before seen (with the exception of films like the Matrix and Minority Report). (44)

The appropriation of space by those in power through technology can also be utilized by the public who can be “empowered by the same kind of technologies that be used to destroy their liberties,” expanding on ideas of crowdsourcing, pop-up, or DIY cities.  (45)  Our living in the “maximum-surveillance society” means that these data are the most “powerful commodity in the informational smart city” (46) and become methods of control under the guise of safety, while also blurring lines between public and private spaces, ultimately concluding that Smart Cities perhaps lead more likely to dumb citizens.

Taking the idea presented above for appropriation of the tools of those in power to fight against that power, Stephen Graham’s “Countergeographies” (55) provides a framework for complementing the traditional methods of protest with new ideas of “Cartographic Experimentation”.  A number of examples are explored, falling into categories of Exposure, Juxtaposition, Appropriate, Jamming, Satire, and Collaboration, the essay provide multiple ideas of new ways of engagement that are more “emergent, fluid and pluralized.”  These experiments are useful but limited, as the author mentions, because of their lack of legitimacy – as art and activism versus being mainstream and political, but that a new wave of activists can adapt and expand them into the lexicon of more traditional forms of protest.

A historical path taken by Fionn Byrne in the essay “Operational Environment” (62) touches on some of the military roots of site design, including Le Notre and Vauban’s spatial reactions of “ballistic trajectories” (64) and the more modern appropriation by landscape architects and planners of military aerial imaging for analysis and ecological planning ala McHarg and modern GIS.  This reduction of landscape and environment to “quantifiable data” as referenced by Waldheim leads to a methodology for militaristic problem solving, where “The force of the military’s technological, informational, and industrial apparatus is being set upon the environment, reducing nature to both a resource as standing reserve on the one hand and a technological-controlled, environmentally managed set of ecosystems on the other.” (66)

A more site specific and compelling examination relevant to design in many was is the essay by Patrizia Violi in “Traumascapes: The Case of the 9/11 Memorial”. (70)   Taking one of the most visible examples of memorial in modern history as point of departure, Violi wonders the role of these places in “constructing, transmitting, and defining a collective memory,” and using the metaphor of memorial as text to show how

“historical memory is not something well defined once and for all, but rather something  that is changing continuously over time.  The actual events themselves are remembered differently, according to the different discourses, texts, images, symbols and gestures produced in relation to them.” (72)

Which is perhaps the dilemma of the legibility of any space, especially ones by which interpretation is a key element, telling a story requires framing (spatially and as a narrative) the elements of what are important, but also set up a sequence and path in which the story is told.  Using the 9/11 memorial and the chasms created by the designers are indicative of the idea of Index, as referenced to Charles Sanders Pierce, in which “…a sign that exhibits a direct, causal link to the actual event that produced the sign, and which the sign itself, in its turn, signifies.” In this way, using the voids of the towers and their “material traces of the past, with direct spatial links to it, and this endows them with a very unique type of meaning.” (73)

While the potential is there for connection of space and event, it is much to ask, the social and cultural functions of ‘trauma sites’ are more indistinct, as the author concludes: “We cannot expect a memorial to capture the complexity of an event of this magnitude, or account for the whole chain of events that follow the initial principal trauma” (75)

This is also echoed by Nicholas Pevzner in “Trees and Memory in Rwanda” (78) where he connects the forest and remnant trees as symbols of ecological devastation, war and economic disasters throughout the country.  In particular the unintended memorialization a the Umuwmu tree, a species of Ficus that were typically planted near houses and are sacred.  These lone trees and groves left now are reminders of houses burned down through strife, a subtle way of remembering past, “symbols of atonement as well as victimization” (81)  Another poignant example in the essay was the use of trees in conflict between the Israeli people (who plant pine forests on lands in attempts to claim land) and the Palestinians who plant olives to mark ownership.  The battle of lands plays out in Israeli’s bulldozing Olive groves, and Palestinians using arson to burn pine plantations.  Both stories show the role of landscape not as innocuous field of war, but as part of the strategy.

One of my favorite essays was an enlightening take on the structure of the refugee camp, ‘Emergency Landscapes’ by Jim Kennedy, (84) who is a shelter and reconstruction professional, and his experiences with informal settlements.  The United Nations High Commissioner for Refugees (UNHCR) establishes guidelines for these camps, but “neglect to take into account the rapidly evolving landscape built upon the camp by the inhabitants themselves, and the complex economies and social networks which expand into these landscapes.” (86) The quidelines themselves were designed for short term (natural disasters) but are insufficient to handle long(er) term occupations of many months or years, which is more common in areas where armed conflict makes early return impossible. So residents have taken the blueprint and using the “malleable materials” people “build barriers, food stalls, paths, roads” and other spaces.

This process is not always democratic or ad hoc, but is often used to create power dynamics with camps of the haves and have-nots, with processes that limit access, create walls and other enclosures to privatize spaces, and create better conditions for some at the expense of others.  Without an “idea of what is a good camp” the question of these longer-term occupations will always be fluid, and Kennedy sees a role for landscape architects in both analysis through observation and research of the morphology (shape), operations (use) and performance (good or not?) of these spaces, as well as to establish and “inform incremental, cumulative, and mosaic approaches.” (89)

‘The Rise of Stateless Space’ by Casey Lance-Brown (92) delves into the amorphous “pockets of absence… where the rule of law is questionable,” those “contested spatial zones [where] the normal laws and standards of protections no longer apply.” (94)   Using the examples of Border Patrol zones in Mexico, the focus of policing certain zones against smugglers, which moved illegal activities to more hostile and remote areas, which led to more deaths and also more extensive ecological destruction, disruption to wildlife, and other impacts.  Layers of “spatial ambiguity” (96) can be smaller scale or global, with DMZs and contested territories, but remind me of further readings on Heterotopias and Terrains Vague, that  expand these notions and provide interesting perspective on the role of the state and the variety of interactions with less control that are compelling to thing of in terms of emergent urbanism.

Tyranny-14_600

Some final essays I thought were less engaging, including a rather flat book review of ‘Architecture and Armed Conflict’ by Nick Mclintock (100) and  ‘The Tyranny of Speculative Urbanism’ by Christopher Marcinkoswki, (104) where he makes the case that tyranny exists in the development of speculative urbanization due to the exploitation of ‘vanity pursuits’ through real-estate developments.  Through examples, many from Africa, he shows that typically urbanization is often regarded in a positive frame as growth (good), however, it is used in nefarious ways in not really creating places of real worth but as a way to generate capital or to generate global competitiveness instead of addressing real issues that regions should be focusing on.  While it is clear that  urbanization is not neutral, this isn’t really new ground on which to tread, as criticism of misguided eco-cities has been kicking around for a while, and green inspired development for even longer.  In concept it is somewhat interesting, but the essay itself doesn’t really come together beyond a few examples, nor did it really elevate to the magnitude befitting the tyrannical.

On that same note, after reading the collective works, the closing essay ‘The Innocent Image’ (114) where Richard Weller offers a cranky argument about the overly photo-shopped project imagery, comes off as tired, and also doesn’t really fit the frame of this issue in terms of focus.  The tyranny of ‘Planet Photoshop’ doesn’t match that of the urgency that the rest of the journal holds.

The wide array of voices that are not typically part of landscape architecture discourse is perhaps the best part of the journal.  I kept a list as i was going, and the diversity includes geography, architecture history, humanities, sociology, urban management, semiotics, art, urbanism as well as landscape architecture, to name a few.  It’s a type of dialogue that is outside of the landscape architectural mainstream (with the exception of academia) and it’s good to get perspectives I’d equate more to a broader Urban Studies focus woven into LA discourse – reinforcing the plus of the LA+ brand.

A series of illustrations woven throughout the journal that explored a variety of topics in visual form – which although sometimes interesting, did little to add to the content in meaningful ways.  Aside from that, some may struggle to find the links to practice of landscape architecture, and there are definitely a few essays that maybe float to those fringes, but most included illuminate a multitude of perspectives beyond theory and provide solid fundamental issues relevant to practice.  And that is what a journal should do, ably demonstrated by LA+ as it has emerged, now the third issue, as a unique voice in the landscape architecture and urbanism discourse.   This one is a dense read, but compelling and relevant.

PA35: Going Live

I was really excited to receive the latest version of  Pamphlet Architecture, published by Princeton Architectural Press.  While I’ve not seen all of them, i do have at least a dozen, and they offer focused snapshots of theory and practice both as well as a longitudinal section of though spanning decades.  My first experience was PA15: War and Architecture featuring Lebbeus Woods, which i picked up as an undergrad and was blown away.  I’ve since picked up issues sporadically, including the great PA21: Situation Normal featuring the work of Lewis.Tsrumaki.Lewis (1998), PA23: Sites of Trauma with Johanna Saleh Dickson (2002),  PA28: Augmented Landscapes by Smout Allen (2007), and PA30: Coupling featuring work and thoughts by InfraNet Lab and Lateral Office (2011).

The most recent version, PA35: Going Live: From States to Systems, was published earlier in November, edited by Pierre Bélanger and featuring work from his design research arm opsys.

PA35_cover

I thought Bélanger’s  essay ‘Synthetic Surfaces’ in the Landscape Urbanism Reader, was interesting, and was interested to see the work as well from he and others around this topic.  For starters, some context, via the blurb snipped below on Amazon:

“”If landscape is more than milieu or environment, and encompasses a deterritorialized world, then it is the contested territory, hidden actor, and secret agent of the twentieth century. Stemming from the early work of some of the most influential landscape urbanists–Frank Lloyd Wright, Ludwig Hilberseimer, Benton MacKaye, Patrick Geddes–this mini manifesto explores underdeveloped patterns and unfinished processes of urbanization at the precise moment when environmentalism began to fail and ecology emerged between the 1970s and 80s. Informed by systems thinking from the modern atomic age, this slim silver pamphlet takes inspiration from Howard T. Odum’s big green book A Tropical Rain Forest and brings alive the voices of a group of influential thinkers to exhume a body of ideas buried in the fallout of the explosion of digitalism, urbanism and deconstructivism during the early 1990s. Catalyzed by Chernobyl’s nuclear reactor meltdown, a counter-modernity and neo-urbanism emerged from the fall of the Berlin wall and the end of South African Apartheid. What happened during this concentrated era and area of change–across design, from architecture to planning–is nothing short of revolutionary.” 

PA35_screen pp34-35

The opening essays start provide some more context, and the crux is really what is said about the timing of the emergence of ecology in the 70s and 80s and how this is now fully integrated, after almost 50 years, into practice.  I do want to find a copy of Odum’s ‘A Tropical Rain Forest‘ after reading the introductory info – perhaps the biggest gem this small volume offers.

Readers should be warned, this is not a trifle, but a dense exploration with a number of unexplained references and jargon – the kind of stuff that makes people roll their eyes and dismiss academic posturing as oh so much BS.  Frankly the intro is probably one of the most annoying passages I’ve read in a while and the first sections were equally obtuse.  It evens out a bit as you continue, but coupled with way too small text and only black and white imagery, it’s a bit of a slog.  As in not enjoyable to read or engage in.

PA35_screen pp18-19

PA35_screen pp36-37

So if you’re still with me – check out the diagrams, and maybe read a section or two.  When you get into them, are quite beautiful and the text has value – exploring some of the themes of landscape and infrastructure from Keller Easterling and Sanford Kwinter.  Go to well lit room, with a magnifying glass and a lot of coffee and have fun.

PA35_screen pp38-39

PA35_screen pp48-49

I was initially put off by the reliance on only black and white imagery, as it seems anachronistic, more of a trope than a reason for its use in this particularly context.  But they work and the idea of communication that transcends color – in these densely packed montages attempt to communicate a ton of info – sometimes it works, sometimes it doesn’t.  Probably the best part of this volume – sometimes it’s amazing and you find yourself staring at a page for way too long.  If they were 2x as big it’d be even better.

PA35_screen pp58-59

So as far as the takeaway for he at this point, I’m really intrigued by the graphics, and some of the experimentation.  While i was initially put off by the black at white imagery, as i mentioned, but after looking at it multiple times, and viewing digital images, it does have a quality that perhaps obscured by our typical splashes of color.

Even as a pamphlet – the writings, well, I feel would have benefited greatly from a tougher editor that reined in some of the language and obscure references.  I’ve read enough academic and dense writings that i can muddle through the most difficult, so  I definitely don’t need my hand held. But there were so many opportunities to add one small explanation of a concept, rather than just leave the reader hanging, or googling, to understand some obscure reference or word choice.  Belanger’s other writings didn’t seem so hard to parse.  This was exhausting.

Sensing Water

A cool use of art to activate some overpasses in San Jose, California by Seattle based artist Dan Corson.  The first is called ‘Sensing WATER‘ which projects lighting on the underpass based on weather conditions.  From the site:

Sensing WATER is a weather-responding and interactive artwork utilizing light and paint to define a major downtown gateway in San Jose CA. The project is composed of 2 elements, the massive painted sloped wall that abstractly references flowing water, and the overhead evening lighting that illuminates with rippling patterns of light the underpass of I-87. The project uses real-time NOAA weather data to compose different patterns of light on the ceiling. (e.g.: 0-5mph winds vs thunderstorms). The projected light maintains a similar palate to the painted sloped wall, yet becomes dynamic depending on the weather.

The use of real time sensing to activate the space, which sits atop the Guadalupe River.  Corson was “… curious to link both the awareness of water issues to the new focus of the high tech industry through the use of dynamic illumination.”

corson_water2

Another take on the underpass is ‘Sensing YOU‘,  which is more interactive, allowing users to control the patterns with an app/game from their cellphones.  The goal in this case, like above, is also to “link technology and nature in this urban landscape sitting over the Guadalupe River- at the heart of Silicon Valley.”  Some more info:

“Sensing YOU is an interactive artwork utilizing light and paint to define a major downtown gateway in San Jose CA. The installation is defined by over 1000 painted circles and 81 individually controlled illuminated rings that play a variety of patterns and low-resolution mapped video over the ceiling surface of the I-87 highway underpass. The patterns are activated by pedestrians and bicyclists moving through the space- setting off pre-programmed sequences.”

Treescrapers

A recent post from CityLab delves into an on-going.  Entitled ‘Are ‘Treescrapers the Future of Dense Urban Living?’, explores the concept beyond the fantastical and thinks about this type of work in terms of reality and the more pragamatic elements.  Weird Dune references about Passive House designers (?) aside, having some critical evaluation the points that were brought up by the architect in the story are valid.

I do think that the focus of the comments maybe relied a bit too much on the particular type of work (i.e. hyper efficient building envelope).  If you see everything through the lens of Passive House, and energy envelopes and embodied energy for structural upgrades, you may miss the trees and the forest.

Admittedly, I am both a supporter and critic of the idea, which I’ve been referring to as Vegitecture (not Treescraping, for hopefully obvious reasons) for some time now.  Beyond being an aesthetic choice which has strong biophilic connections, there’s ecological and even, yes, energy considerations with integrating vegetation into buildings.  It’s definitely a key strategy for a less building centric idea of passive heating and cooling, which has to me has always included vegetation surrounding structures as part of the equation – using evergreen vegetation to block colder winter winds and shade for cooling and deciduous to provide summer shading and opening up during winter for additional heating/sun after leaf drop.  That diagram I think i first say in first year intro to landscape architecture.

la-passivecooling

Of course everything comes at a cost, so an accounting of cost to benefit is necessary, but that cost also much include other items in the ledger, like health benefits of access to nature, additional passive cooling and heating benefits that could be integrated with exterior and interior system integration.  The opportunity is to make these projects work and think of new ways to better integrate them into the buildings in artful and functional ways.

I’ve discussed typologies before, and it’s interesting to see the evolution of the types, from building integrated living walls above, to terrace planters, roofs decks, more traditional green roofs, and much more.  The possibilities in photoshop, alas, are endless.  But in reality, there are some additional considerations, all of which should be taken into account.  Some more images of green on buildings – nothing new here on this blog.  More at the original post on CityLab as well

And these definitely trend towards the fantastic, which is part of the reconciliation between what can actually work and what looks cool in a rendering.  So, yes, that involves messy practicalities the additional structural loading, and how to incorporate thermal breaks, and many others like how to maintain vegetation, how to irrigation, issues of wind uplift, leaf litter, structural capacity, and many more.  Great discussions, and necessary ones, as we grow and evolve the concept.
