How biology informs resilient design

We’ve just come across a very thoughtful article by Michael Mehaffy and Nikos Salingaros called “Toward Resilient Architectures 1: Biology Lessons” in MetropolisMag.

Mehaffy and Salingaros draw a number of lessons from biological systems and use them to draw conclusions about how resilient human systems must be designed. Here’s what they suggest resilient cities must be like:

1) They have inter-connected networks of pathways and relationships. They are not segregated into neat categories of use, type, or pathway, which would make them vulnerable to failure.

2) They have diversity and redundancy of activities, types, objectives, and populations. There are many different kinds of people doing many different kinds of things, any one of which might provide the key to surviving a shock to the system (precisely which can never be known in advance).

3) They have a wide distribution of scales of structure, from the largest regional planning patterns to the most fine-grained details. Combining with (1) and (2) above, these structures are diverse, inter-connected, and can be changed relatively easily and locally (in response to changing needs). They are like the small bricks of a building, easily repaired when damaged. (The opposite would be large expensive pre-formed panels that have to be replaced in whole.)

4) Following from (3), they (and their parts) can adapt and organize in response to changing needs on different spatial and temporal scales, and in response to each other. That is, they can “self-organize.” This process can accelerate through the evolutionary exchange and transformation of traditional knowledge and concepts about what works to meet the needs of humans, and the natural environments on which they depend.

By contrast, as the authors detail, our existing cities are for the most part non-resilient. This is the first of a five-part series; we’re looking forward to the rest. Read the full article here.

Update: Here’s Part 2: “Toward Resilient Architectures 2: Why Green Often Isn’t”

And here’s Part 3: “How modernism got square”

David W. Orr is Paul Sears Distinguished Professor of Environmental Studies & Politics, Emeritus. He also served as “Counselor to the President” of Oberlin College for ten years. He is the author of eight books, including Dangerous Years: Climate Change and the Long Emergency (Yale, 2016) and Down to the Wire: Confronting Climate Collapse (Oxford, 2009) and co-editor of three others. He has authored over 220 articles, reviews, book chapters, and professional publications. In the past twenty-five years he has served as a board member or adviser to ten foundations and on the Boards of many organizations including the Rocky Mountain Institute, Bioneers, and the Aldo Leopold Foundation.

He is currently a Trustee of the Alliance for Sustainable Colorado, Children and Nature Network, and the WorldWatch Institute. He has been awarded nine honorary degrees and a dozen other awards including a Lyndhurst Prize, a National Achievement Award from the National Wildlife Federation, leadership awards from the U.S. Green Building Council (2014) and from Second Nature (2012), and a lifetime achievement award from Green Energy Ohio and the North American Association for Environmental Education. He has lectured at hundreds of colleges and universities throughout the U.S., Europe, Latin America, and Asia. He headed the effort to design, fund, and build the Adam Joseph Lewis Center, which was named by an AIA panel in 2010 as “the most important green building of the past thirty years,” as “one of thirty milestone buildings of the twentieth century” by the U.S. Department of Energy, and as one of “52 game-changing buildings of the past 170 years” by the editors of Building Design +Construction in January, 2016. He was instrumental in the design and funding of the Peter B. Lewis Gateway Center. He is the founder of the Oberlin Project and a founder of the journal Solutions. His current work is on the state of American democracy.
