Abstract

This study extends the Protective Action Decision Model, developed to address disaster warning responses in the context of natural hazards, to boil water advisories. The study examined 110 Boston residents' and 203 Texas students' expectations of getting sick through different exposure paths for contact with contaminated water. In addition, the study assessed respondents' actual implementation (for residents) or behavioral expectations (for students) of three different protective actions - bottled water, boiled water, and personally chlorinated water - as well as their demographic characteristics and previous experience with water contamination. The results indicate that people distinguish among the exposure paths, but the differences are small (one-third to one-half of the response scale). Nonetheless, the perceived risk from the exposure paths helps to explain why people are expected to consume (or actually consumed) bottled water rather than boiled or personally chlorinated water. Overall, these results indicate that local authorities should take care to communicate the relative risks of different exposure paths and should expect that people will respond to a boil water order primarily by consuming bottled water. Thus, they should make special efforts to increase supplies of bottled water in their communities during water contamination emergencies.

Abstract

The Dujiangyan irrigation system, China's largest, is one of the world's most important examples of sustainable agropolitan development, maintained by a relatively decentralised system of governance that minimises bureaucratic oversight and depends on significant local autonomy at many scales down to the household. At its historic core in the Chengdu Plain, the system has supported over 2000 years of near-continuously stable urban culture, as well as some of the world's highest sustained long-term per-hectare productivity and diversity of grain and other crops, especially considering its high population density, forest cover, general biodiversity and flood management success. During the past decade, rapid urban expansion has turned the Chengdu Plain from a net grain exporter into a grain importer, and has radically transformed its productive functioning and distinctive scattered settlement pattern, reorganising much of the landscape into larger, corporately-managed farms, and more concentrated and infrastructure-intensive settlements of non-farming as well as farming households. Community-scale case studies of spatial-morphological and household socio-economic variants on the regional trend help to articulate what is at stake. Neither market-driven 'laissez-faire' rural development nor local state-driven spatial settlement consolidation and corporatisation of production seem to correlate well with important factors of resilience: landscape heterogeneity; crop diversity and food production; permaculture; and flexibility in household independence and choice of livelihood. Management of the irrigation system should be linked to community-based agricultural landscape preservation and productive dwelling, as sources of adaptive capacity crucial to the social-ecological resilience of the city-region, the nation and perhaps all humanity.

Ken Yocom

Ken Yocom is Department Chair and Professor in the Department of Landscape Architecture. He also has an adjunct appointment in the Department of Urban Design and Planning, serves on the steering committee of the PhD in the Built Environments Program, and is core faculty for the Interdisciplinary PhD Program in Urban Design and Planning within the College of Built Environments. He primarily teaches seminar and studio courses in theory, ecology, and urban design.

Trained as an ecologist and landscape architect with professional experience in the environmental consulting and construction industries, he is a graduate of our MLA program (2002). Ken also earned his PhD from the Program in the Built Environments (2007), where he researched nature and society relations through the contemporary context of urban ecological restoration practices.

Ken’s current research, teaching, and practice explore the convergence of urban infrastructure and ecological systems through adaptive design approaches that serve to demystify emerging strategies and technologies for sustainable and resilient development. More specifically, he investigates how water –in all its forms- shapes the past to future functions and patterns of our built environments. He has written extensively on the themes developed from his work including two books, Ecological Design (with Nancy Rottle, Bloomsbury, 2012) and NOW Urbanism: The Future City is Here (with Jeff Hou, Ben Spencer, and Thaisa Way (editors), Routledge, 2014). He has also written for professional practice and scholarly publications on issues of global biodiversity, urban environmental governance, ecological design, and contemporary nature and society relations in the urban context.

In his teaching, Ken emphasizes the development of a holistic and integrated approach that embraces the complexity of our built environments, yet discreetly explores the intersections and overlaps that frame our understanding and appreciation of particular places. He has a strong belief that collaboratively, the allied design professions can act as catalysts in recognizing, utilizing, and transforming the inherent potential of our built environments into places that are socially equitable, environmentally just, and economically sustainable.
