Gund Fellow, Research Assistant Professor, UVM Extension

Joshua Faulkner is a Research Assistant Professor with UVM Extension and also coordinates the Farming and Climate Change Program in the UVM Extension Center for Sustainable Agriculture. Faulkner does applied research and outreach on soil, water, and nutrient related issues across Vermont and the Northeastern US. 

Joshua works with governmental and non-governmental organizations to improve agricultural programs and educate stakeholders, and provides technical assistance and outreach to farmers on practices and innovative solutions to improve management and build resilient, sustainable farming systems.  A changing climate, and its effect on agriculture and resulting water quality, is a key theme in much of his work. Joshua's work spans from the farmstead to the watershed scale, and has included projects in the Chesapeake Bay Watershed and West Africa.
