Tropical Land-use Change and Globalization


My research focuses on tropical land-use change and globalization, particularly on the potential to reconcile food security, climate change and conservation goals. I use data-driven modeling approaches, geographic information systems (GIS) and remote sensing imagery combined with ground-based data on social and biophysical conditions to document and understand patterns, drivers and consequences of land-use change, particularly in the tropics.

Currently, I am examining tropical land-use transitions in response to global economic drivers such as bioenergy mandates and demand-side pressures from Greenpeace and other non-governmental organizations. Specific research questions include – What are the drivers of agricultural land use change? Do bioenergy subsidies in the U.S., Europe and elsewhere influence rates of forest clearing? What role could REDD play in mitigating causes and drivers of deforestation? How have tropical-land use patterns changed over the last three decades? What does this mean for carbon emissions? How can we facilitate low carbon land use and energy strategies?

Throughout my career, I have worked closely with policymakers, business leaders and non-governmental organizations. For nearly a decade, I have served as a science advisor for policymakers from developing countries in support of the UNFCCC initiative to Reduce Emissions from Deforestation and Degradation (REDD). I was also selected to serve on the California Low Carbon Fuel Standard Expert Working Group, where I chaired the Land Cover Change committee. I am committed to mentoring students in GLUE and beyond, and greatly enjoy helping them find ways to use their unique skills and achievements to bring science into action.
