From 2011 through 2017, the National Science Foundation (NSF) supported a collaborative research project on "Urban Sustainability: Research Coordination and Synthesis for a Transformative Future." This project was jointly organized and directed by the Baltimore Ecosystem Study LTER and the Central Arizona Phoenix LTER. Prof. Daniel L. Childers and I were Co-Directors of the project.
The text here is the "plain language" public outcomes report as submitted to the Research.gov website. We hope it gives you some sense of how BES and its partners are helping to promote the understanding and application of the popular and important idea of sustainability. The report is divided into the two sections required by the National Science Foundation -- Intellectual Merit and Broader Impacts.
The Urban Sustainability Research Coordination Network (RCN) was designed to improve the understanding of urban sustainability and to better position ecologists to interact with policy makers and managers concerned with sustainability in cities, suburbs, and urban regions. It was important to focus on urban areas because sustainability research and practice had mainly focused on natural resources, rural systems, or conservation. Because urban systems are becoming ever more important in the United States and around the world, improving the understanding of urban sustainability is a crucial need. Intentionally limited to working with existing data, the Urban Sustainability RCN had four main objectives: 1) to improve the availability of knowledge about the sustainability of urban systems; 2) to generate conceptual frameworks that unify the crucial disciplines needed to understand and facilitate urban sustainability; 3) to identify research needs to enhance the future understanding and application of urban sustainability; and 4) to build a diverse network of sustainability researchers and practitioners.
This RCN began with 37 participants from the United States and 4 other countries. The Network grew to engage 80 researchers, educators, and practitioners from 50 cities in 20 countries. This extensive network brought together a large amount of data, broad experience with cities of different sizes and types, and the insights of various cultural and professional backgrounds. The large size of the Network helped to spread the insights of the intellectual integration very widely around the nation and globe. The growth of the Network also reflected the widespread interest in the topic.
The RCN convened three meetings of the entire group over the course of the grant, plus smaller thematically oriented meetings. The themes evolved during the project based on the "all hands" meetings, and the activities of the working groups. Ultimately, the RCN addressed these themes: 1) conceptual models for urban sustainability; 2) the influence of different formal and informal governance structures on urban sustainability; 3) the role of interdisciplinary insights and contributions of the humanities to improved urban sustainability; 4) how ecologically informed urban design can improve sustainability through attention to adaptive resilience; 5) how urban metabolism, that is, the control of nutrient and energy flow, contributes to sustainability; and 6) the use of scenario planning as a tool to improve sustainable urban futures.
The RCN increased understanding of the social, economic, and environmental triggers that have led cities to crisis and transition, including discriminating the different scales on which the triggers act. This information has been especially useful to reinforcing partnerships with urban sustainability officers. The RCN also employed the idea that urban areas are complex systems, in which triggers affect the adaptive mechanisms that lead toward or away from sustainability. Finally, the RCN employed the interactions between water resources and energy resources to understand important trade-offs that can affect the ability of cities to transition to sustainability.
Several specific outcomes illustrate the practical success of this RCN. One is its serving as a seed bed for the Urban Resilience to Extremes Sustainability Research Network (UREx SRN). This multi-institutional program of research and application, headquartered at Arizona State University, uses several of the conceptual advances generated by our RCN as the stimulus for new data collection. A second major project that emerged from this RCN was funded by Future Earth to investigate sustainability from the perspective of urban phosphorus dynamics. Phosphorus is a significant limiting nutrient in ecosystems and a can be a serious pollutant of surface waters. A third outcome is cementing interactions with the Research Center for Eco-Environmental Sciences of the Chinese Academy of Sciences, to help develop sustainability research in the context of the rapid urbanization now underway in China and elsewhere in developing countries. Interchanges with Network members in South Africa and in Latin America ensure that the insights and needs of very different kinds of urban change have been accounted for in our concepts and in our communication with urban design, planning, and management practitioners. An additional important outcome of the RCN was better linking engineering and urban design perspectives with the important biological basis of sustainability in urban systems.
The RCN trained several students and early career scientists. A total of 20 post-doctoral associates participated as full members of the RCN. The RCN employed Post-doctoral associate Meredith Garten for 2.5 years. She is now a faculty member at Ohio University. Chris Sanchez, Laboratory Manager for PI Childers, assisted with logistics for the RCN after Dr. Gartin’s departure; he is now a doctoral student at Arizona State University. Nicholas Weller, also a doctoral student with Childers, won an NSF EASPI grant to assist with field work on the urban sustainability pilot project funded by the CAS in Beijing in Summer 2016. The interactions with many sustainability practitioners are ongoing. So the network established by this RCN project, continues to advance the conceptual understanding and pathways for application of sustainability.
