My research program is focused on working with farmers, and other managers of agricultural landscapes to find ways to better monitor, protect and enhance biodiversity and the availability of ecosystem services including food, fiber, fuel and timber production, greenhouse gas mitigation, and water quality and quantity regulation. My research has been concentrated on assessing the impact of farm management practices on plant biomass and biodiversity, soil physical and chemical properties, nutrients in water (leaching, and storm and irrigation runoff), and carbon dioxide (CO2) and nitrous oxide (N2O) emissions. I am interested in developing methods to translate these measures of ecosystem function into estimates of the availability of ecosystem services; then to figure out how to accurately bridge results from plot and farm level to those at larger scales, at the watershed, landscape and region using geospatial statistics, remote sensing and geographical information system tools. By providing landscape level assessments I see the possibility for farmers to not only better understand wider implications of their management practices but also to provide decision makers tools to address the increasing need for agricultural landscape to meet multiple societal objectives beyond just food production.

Research Projects

I am in the process of building a research program that investigates the relationship between agriculture and ecosystem services both in developing and developed world agricultural landscapes. I am currently involved in projects investigating tradeoffs among climate change mitigation, plant biodiversity and food security in East Africa and developing methods for implementing, monitoring, reporting and verifying carbon sequestration projects involving small-holder farmers. I am also working on a project to provide land use managers and farmers in southwest Haiti with tools to create effective watershed management plans to meet multiple objectives of an integrated rural development program. New to British Columbia, I am currently starting to develop research projects within the province, particularly focused in and around the city of Vancouver.
