David Anderson
is the OERM Agriculture Senior Technical Assistance Specialist. Climate change has already impacted our food systems by extending the growing degree days, increasing or decreasing rainfall, causing unpredictable spring weather, and shifting the regions of pests and invasive species. This has led to the start of collaborative projects between the USET Climate Program and the Agriculture Program to address these issues with adaptation and mitigation. If you want to connect with us about climate impacts to your landscapes, food system, or farm, please feel free to reach out to David at danderson@usetinc.org.

Rebecca Naragon
is USET’s Economic Development Director. Community and business recovery activities allow for many opportunities for collaboration between Climate Change and Economic Development programs. In this spirit, USET OERM and the Climate Change program has been working with USET’s Office of Economic Development over the past few years on facilitating training workshops and camps, resource and network brokering, and supply chain technical assistance.
