S-D3 Ecosystem Services for Nexus Solutions

The water-energy-food nexus is one important, but as of yet insufficiently explored entry point to improve ecosystem services for people and the environment. The session seeks to explore how the nexus approach can help to secure the sustainable provision and equitable distribution of ecosystem services in various agricultural landscapes across the globe. It aims to examine how increased resource use efficiency through solutions in the water, energy and food sectors ensure that ecosystem services will continue to generate services for future generations and particularly for the poor.

Andrew Reid Bell is Assistant Professor of Environmental Studies at New York University. Prior to joining NYU he was Research Fellow at the International Food Policy Research Institute (IFPRI) in Washington, DC, and Earth Institute Fellow at Columbia University. His work employs modeling tools and economic/behavioral experiments to examine resource behavior in rural contexts; current project areas include Malawi, Pakistan, Bangladesh, Cambodia, and Vietnam.

Prof. Anthony Janetos joined Boston University in May 2013 as Director of the Frederick S. Pardee Center for the Study of the Longer-Range Future and Professor of Earth and Environment. Previously, Prof. Janetos served as Director of the Joint Global Change Research Institute at the University of Maryland, where for six years he oversaw an interdisciplinary team of natural scientists, engineers and social scientists committed to understanding the problems of global climate change and their potential solutions.

Tracy Rouleau is NOAA’s Deputy Chief Economist in the Office of Program Planning and Integration, which is the nexus for coordinating, empowering, and catalyzing the integration of Social Science across NOAA. Her work focuses on NOAA-wide priorities including advancing the integration of ecosystem services into management and policy; improving and maintaining the rigor of NOAA’s high-profile economic data; transitioning research on risk communication and behavior to application; improving coordination and collaboration on socioeconomic datasets and initiatives at the interagency level; and measuring and communicating the value of NOAA’s products and services.

Wei Zhang is a research fellow in the Environment and Production Technology Division. Her research focuses on valuing and modeling ecosystem services for policy-relevant analysis and understanding socioeconomic and behavioral factors in ecosystem services and natural resource management, which often requires cross-boundary coordination, with implications for sustainable agricultural development and poverty reduction. Wei earned a PhD in Agricultural, Food, and Resource Economics at Michigan State University. She has a Master’s degree in Community Development and Applied Economics from the University of Vermont and a BA degree in International Economics from Renmin University in China.
