Global environmental change and sustainability science increasingly recognize the need to address the consequences of changes taking place in the structure and function of the biosphere. These changes raise questions such as: Who and what are vulnerable to the multiple environmental changes underway, and where? Research demonstrates that vulnerability is registered not by exposure to hazards (perturbations and stresses) alone but also resides in the sensitivity and resilience of the system experiencing such hazards. This recognition requires revisions and enlargements in the basic design of vulnerability assessments, including the capacity to treat coupled human–environment systems and those linkages within and without the systems that affect their vulnerability. A vulnerability framework for the assessment of coupled human–environment systems is presented.
Research on global environmental change has significantly improved our understanding of the structure and function of the biosphere and the human impress on both (1). The emergence of “sustainability science” (2–4) builds toward an understanding of the human–environment condition with the dual objectives of meeting the needs of society while sustaining the life support systems of the planet. These objectives, in turn, require improved dialogue between science and decision making (5–8). The vulnerability of coupled human–environment systems is one of the central elements of this dialogue and sustainability research (6, 9–11). It directs attention to such questions as: Who and what are vulnerable to the multiple environmental and human changes underway, and where? How are these changes and their consequences attenuated or amplified by different human and environmental conditions? What can be done to reduce vulnerability to change? How may more resilient and adaptive communities and societies be built?
Answers to these and related questions require conceptual frameworks that account for the vulnerability of coupled human–environment systems with diverse and complex linkages. Various expert communities have made considerable progress in pointing the way toward the design of these frameworks (10, 11). These advances are briefly reviewed here and, drawing on them, we present a conceptual framework of vulnerability developed by the Research and Assessment Systems for Sustainability Program (http://sust.harvard.edu) that produced the set of works in this Special Feature of PNAS. The framework aims to make vulnerability analysis consistent with the concerns of sustainability and global environmental change science. The case study by Turner et al. (12) in this issue of PNAS illustrates how the framework informs vulnerability assessments.
role play simulation modeled around Michigan wolf management. In this case, role play simulation is a game fabricated to reflect the complexity of real-world conflict. The goal of the exercise is to engage players in mock negotiation and expand their knowledge of wicked environmental problems. By encouraging participants to question their own thought process, the activity aims to foster a transformational experience.
Interview with J.D. Hill, co-founder of Recycled City
J.D. Hill is the co-founder of Recycled City LLC a business devoted to building a revolving relationship within the local food economy by limiting food waste. His business provides materials to create compost out of waste materials for residential customers and business. J.D.’s goals with his business are to inspire the community to participate in their local food economy, promote activism, focus on building farm land, and encourage a green economy in the Valley area. He is an ASU grad with degrees from the School of Sustainability and the W.P. Carey School of Business. This knowledge has shaped his view toward the ability of green businesses to flourish in the Phoenix area.
Interview with Mr. Arnott Duncan, owner of Duncan Family Farms, Inc.
Arnott Duncan is the owner of Duncan Family Farms. Farming runs in Arnott’s veins. He is a third generation farmer who has developed a deep connect to his local economy. However, interacting with Arizona food systems is not his only goal. Arnott also is actively engaged with educating the community about local produce. His farm provided U-Pick opportunities to the local community to provide people with in engaging experience toward food. The many years Arnott spent in the food industry has taught him that food, family, and community change the way we think but what we choose to do with that makes the difference in how we shape the world.
