Adaptation, environmentalism, and climate change

Some links on the evolution of environmentalism and adaptation in the face of climate change:

The Anthropocene: Over at Time, Bryan Walsh has a piece on the rise of the Anthropocene Era – an acknowledgement of the human impact on the Earth. Walsh links to a Slate piece by Keith Kloor on the tension within the environmental movement between pragmatic greens and old-school environmentalists.

Part of the tension is between pragmatism and purity. The idea of adaptation to our environment and the realization that there is no such thing as a pure ecosystem is jarring to older greens. From Kloor’s article:

Leading the charge is a varied group of what I call modernist greens (others refer to them as eco-pragmatists). They are people with deep green bona fides, such as the award-winning U.K. environmental writer Mark Lynas, whose book The God Species champions nuclear power and genetically modified crops as essential for a sustainable planet.

Another is Emma Marris, author of the critically acclaimed Rambunctious Garden: Saving Nature in a Post-Wild World. She argues that “we must temper our romantic notion of untrammeled wilderness” and embrace the jumbled bits and pieces of nature that are all around us—in our backyards, in city parks, and farms.

You can see this same sort of tension in other places as well, such as the debates around growth within cities.

Adaptation and climate change, part 1: In the aftermath of Sandy, New York is facing questions about how to deal with future storms.  Hard barriers and sea walls are apparently off the table, but other hardening of infrastructure is under consideration. Likewise, relocation is on the table, at least in the abstract.

Compare that map of New York’s historical wetlands to the New York Times’ map of flooded areas and depths.

Softer barriers, making use of dunes and other natural elements are one option – embracing the natural ecology of New York’s coastline to defend the city from storms, while manipulating the natural ecosystems for the ends of the city.

At the same time, it’s worth considering how those vulnerable areas ended up densely populated with New York’s poor in the first place.

Adaptation and climate change, part 2: Another change in need of adaptation is not storms, but heat. The Atlantic Cities looks at future heat waves on the east coast, based on climate models.  The increased heat isn’t quite as bad as the Mayan Apocalypse forecast, but still a bit on the warm side.

Adaptation via migration: One option under consideration would be to adapt to a changing climate and rising sea levels by simply migrating to places with more favorable conditions.  At the Economist, this video conversation featuring Ryan Avent (entitled “Goodbye New York, Hello Minneapolis”) discusses just that.

One topic is the three ways to deal with climate change.  Mitigation is one (e.g. reducing greenhouse gases to reduce the impact), adaptation is another (e.g. moving to higher ground), but the third is suffering.  A common thread in the two articles linked above discussing the Anthropocene and the new pragmatism among environmentalists is a sense of optimism.  Bryan Walsh writes this:

The modern greens paint an optimistic picture, and that in itself is a welcome change from the relentlessly pessimistic scenarios we’ve become accustomed to —a pessimism, it should be noted, that hasn’t been all that effective in marshaling public opinion. But the optimism of the modern greens is conditional on two points: first, that we have the ability and the will—politically and perhaps even biologically as a species—to plan properly for the Anthropocene. (We may be as gods, but I see plenty of evidence to suggest that we’ll never get good at it.) Second, we have to hope that nature really will prove resilient in the face of pollution, growing human population and most of all, climate change, which we show virtually no sign of being able to slow in the near future.

There are questions about both our ability to mitigate and to adapt, but the question of how much suffering is also unknown.

Adaptation in housing, organically

A few housing-related tidbits that I’ve accumulated over the past week.

Richard Layman laments the lack of quality development, noting the difficulties involved with larger scale infill projects, especially when compared against smaller scale renovation projects of single rowhouses or small apartment buildings.  The smaller scale renovations take on a more organic character, while the scale of the larger projects necessitates more centralized planning and development.

As for your point about “organic” development, in my experience, which I admit is relatively limited, my sense is organic (re)development that includes significant amounts of new construction is more about adaptive reuse of extant places, complemented by (hopefully high quality) infill.

Along similar lines, Rob Holmes over at mammoth points to a great discussion of housing in Haiti (Incremental House, Wired), with a particular focus on adaptation and organic elements.  This isn’t the first time mammoth has mentioned the idea of incremental housing development, which Rob touched on in his very interesting list of the best architecture of the decade (including more infrastructural/engineered spaces like the Large Hadron Collider).  Quinta Monroy, an incremental housing project in northern Chile, has a fascinating approach to both building shelter and also growing and adapting with the residents:

Quinta Monroy is a center-city neighborhood of Iquique, a city of about a quarter million lying in northern Chile between the Pacific Ocean and the Atacama Desert.  Elemental’s Quinta Monroy housing project settles a hundred families on a five thousand square meter site where they had persisted as squatters for three decades.  The residences designed by Elemental offer former squatters the rare opportunity to live in subsidized housing without being displaced from the land they had called their home, provides an appreciating asset which can improve their family finances, and serves as a flexible infrastructure for the self-constructed expansion of the homes.

Quinta Monroy

Elemental’s first decision was to retain the inner city site, a decision which was both expensive and spatially limiting: there is only enough space on the site to provide thirty individual homes or sixty-six row homes, so a different typology was required.  High rise apartments would provide the needed density, but not provide the opportunity for residents to expand their own homes, as only the top and ground floors would have any way to connect to additions.  Elemental thus settled on a typology of connected two-story blocks, snaking around four common courtyards, designed as a skeletal infrastructure which the families could expand over time:

We in Elemental have identified a set of design conditions through which a housing unit can increase its value over time; this without having to increase the amount of money of the current subsidy.

In first place, we had to achieve enough density, (but without overcrowding), in order to be able to pay for the site, which because of its location was very expensive. To keep the site, meant to maintain the network of opportunities that the city offered and therefore to strengthen the family economy; on the other hand, good location is the key to increase a property value.

Second, the provision a physical space for the “extensive family” to develop, has proved to be a key issue in the economical take off of a poor family. In between the private and public space, we introduced the collective space, conformed by around 20 families. The collective space (a common property with restricted access) is an intermediate level of association that allows surviving fragile social conditions.

Third, due to the fact that 50% of each unit’s volume, will eventually be self-built, the building had to be porous enough to allow each unit to expand within its structure. The initial building must therefore provide a supporting, (rather than a constraining) framework in order to avoid any negative effects of self-construction on the urban environment over time, but also to facilitate the expansion process.

Obviously, applying this idea to a western city (as opposed to a slum) raises a whole different set of issues, but it’s a particularly interesting idea when contrasted against the highly planned and professionally designed structures Richard Layman notes.  It provides a jumping point to look at the continuum between several of the elements that the Incremental House mentions in their self-description:

Much of the housing around the world occupies a space in between the planned/unplanned, formal/informal and the professional/non-professional, offering people a small space space to negotiate the tremendous shifts taking place in the urban landscape.

DC’s stability provides less of an opportunity to shift between those poles, but the idea is nevertheless interesting.  Rob Holmes expands on what this means:

Elemental, in other words, have exploited the values and aims of ownership culture (which mammoth has suggested understands the house to be first a machine for making money and only second to be a machine for living) not to support a broken system of real estate speculation and easy wealth, but to present architecture as a tool that can be provided to families.  While the project is embedded with some of the assumptions of the architects (such as that faith in the potential of ownership culture, for better or worse), this tool is primarily presented as a framework, a scaffolding upon which families are able to make their own architecture.

Framework is a good way to put it – much of the work in planning seeks to establish frameworks (legal, physical, financial) around which cities and grow, evolve, and adapt – Layman’s point shows there is more we can do on that front.
