Overview
Alex Pfaff is a Professor of Public Policy, Economics and Environment at Duke University. He studies how economic development affects and is affected by natural resources and the environment. His focus is on the impacts of conservation policies (such as protected areas, ecoservices payments, and certifications) and development policies (such as roads and rights). Those impacts are functions of choices by individuals and communities that affect land use, water quantity and quality, human exposures (to arsenic, mercury, mining, and particulates), and both the provision and use of information.
