In the current Anthropocene Era environmental, resilience can be defined as the capacity for urban settlement to withstand and/or recover from negative settlement environmental impacts . This in turn relates to the metabolism of the settlement, particularly with regard to various embodied flows of water, energy and material stocks measured in metric tons per year or similar and directly attributable to the settlement. In this research, stock-flow models were devised using available data characterizing the metabolism of various domains of human co-existence . These included peripheral settlement in metropolitan regions, such as the Dedham, Westwood and Norwood area of Boston in the United States. Flows were then represented emanating from sources in the geosphere, biosphere and hydrosphere of natural circumstances through the production of materials and other physical settlement resources and on to uses and then waste disposal, including recycling . From this ‘cradle-to-end use’ description major vulnerabilities to resilience became readily apparent, including excessive paving, material consumption and waste. Amelioration of the vulnerabilities could then be identified and remodeled with regard to improvements through technological and urban design interventions.
The Dedham, Westwood and Norwood area under study was defined by three zip codes and census tracts. It is located on Route 128 encircling the periphery of Boston as part of the World War II Federal Highway Program . It has an area of some 83,000 square kilometers and a population of some 28,000 households. It also embraces sensitive natural environmental areas within the Neponset River Watershed and is otherwise comprised of patches of mainly single-family residential development and pockets of commercial and industrial use, usually adjacent to Route 128.
In the recycled version of the water flow model, 57 percent of the original wastewater was returned, reducing the extraction of both surface and ground water, even though Boston is not a water stressed area. This did, however, suggest a reduction in necessary infrastructure. Improved conditions for energy consumption could be achieved in several ways. This included use of electrical vehicles, with much of electrical power coming from hydro sources. It also included substantial gains from heating and cooling using geothermal resources and solar panels, as well as increased residential densities using buildings on sites already served by paved surfaces. Plans were also imagined where excessive paved areas were converted to greenways integrated back into adjacent or neighboring forested preserve areas. Modeling indicated that these measures could reduce energy consumption by as much as 50 to 60 percent. Overall, through the stock-flow re-writing, so to speak, of existing development, targets of opportunity for better environmental performance in peripheral settlement could be identified. Currently, further work is being dedicated to improving both the input and output functions of the current models, as well as improving the aging capabilities of especially the material flows over time. Also on the agenda is a better and more nuanced description of life-cycle aspects of constructed environments, as well as more complete documentation of modeling and data processes.
