Planning and Land Management in Tropical Ecosystems: How Does Land Management Affect Hydrologic Ecosystem Services? Fred L. Ogden Cline Distinguished Chair of Engineering, Environment, and Natural Resources, University of Wyoming The Panama Canal Watershed provides an opportunity to study the effectiveness of payment for ecosystem services (PES) schemes in a tropical watershed, due to an ongoing PES program there. While spending on the program is known, the socio‐economic and environmental benefits are loosely quantified. To understand the effectiveness of the paid‐for land management schemes, we have instrumented study catchments that have identical geology, soils, topography, and weather/climate forcing, but different land uses and land‐covers. Our hydrological studies are aimed at developing predictive understanding of hydrological response and behavior as a function of land use, land‐cover, and land use history. This understanding will help to quantify economic and desired hydrological services through modeling of PES effects. 12:00‐1:00 FREE EVENT in Burke Auditorium, Kroon Hall Lunch will be provided – first come, first served
