ItemGrowing Cities Depend on Ecosystem Services(Solutions for a Sustainable and Desirable Future, 2011) Ervin, David; Brown, Darrell; Chang, Heejun; Dujon, Veronica; Granek, Elise; Shandas, Vivek; Yeakley, AllenMany studies have documented the growing fragility of a majority of the globe’s ecosystems. Policymakers and resource managers often frame such ecosystem challenges as primarily about protecting natural systems in rural areas. However, that conception misses a key part of the story: the rapid growth of urbanizing areas. Home to more than 50 percent of the world’s human population for the first time in modern history, urbanizing regions concentrate pressure on ecosystem services, which are necessary to sustain healthy urban living conditions and vibrant commerce. This dramatic urbanization presents both challenges and opportunities for novel ecosystem services management. A transdisciplinary framework is needed to discover innovative solutions to these wicked problems because they involve complex linkages between natural and human systems that transcend any single discipline. The framework should integrate natural and social sciences with stakeholders’ intimate knowledge of ecosystem services and urban systems. Here we describe such a framework for training scientists and managers and present four novel cases that illustrate ecosystem management solutions for urbanizing areas. ItemValuing ecological systems and services(F1000, 2011) Costanza, Robert; Kubiszewski, Ida; Ervin, David; Bluffstone, Randy; Boyd, James; Brown, Darrell; Chang, Heejun; Dujon, Veronica; Granek, Elise; Polasky, Stephen; Shandas, Vivek; Yeakley, J. AlanMaking trade-offs between ecological services and other contributors to human well-being is a difficult but critical process that requires valuation. This allows both better recognition of the ecological, social, and economic trade-offs and also allows us to bill those who use up or destroy ecological services and reward those that produce or enhance them. It also aids improved ecosystems policy. In this paper we clarify some of the controversies in defining the contributions to human well-being from functioning ecosystems, many of which people are not even aware of. We go on to describe the applicability of the various valuation methods that can be used in estimating the benefits of ecosystem services. Finally, we describe some recent case studies and lay out the research agenda for ecosystem services analysis, modeling, and valuation going forward.
