Karla L. Hanson, PhD
Dr. Hanson’s research primarily focuses on food security, food access, and dietary quality in the U.S., with a particular emphasis on public policies affecting low-income families with children. She uses both quantitative and qualitative research methods to explore food security and access to healthy food through farmers’ markets, community supported agriculture, home and community gardening, civic engagement, and systems of mutual aid.
In partnership with Mutual Aid Tompkins (MAT), undergraduate and MPH students are working with Dr. Hanson to understand the operations of food sharing cabinets located throughout Tompkins County. Operating under the principle of “neighbors supporting neighbors to meet survival needs,” MAT food sharing cabinets are in outdoor locations that can be accessed by residents who have food to share and residents who need food. The research team is using a variety of methods to estimate the flow of food into and out of food sharing cabinets; to assess satisfaction, barriers, and perceived impact of use of food sharing cabinets; and to explore community connectedness.
Dr. Hanson is collaborating on research into food self-procurement strategies (i.e., foraging, gardening, fishing, and hunting) and reliance on locally sourced foods in the context of the COVID-19 pandemic in New York State. Findings from this study will inform both efforts to support people currently in crisis and future food system planning.
With funding from the U.S. Department of Agriculture and partnerships with cooperative extension and 12 farms, Dr. Hanson and collaborators recently completed The Farm Fresh Foods for Healthy Kids (F3HK) intervention trial. F3HK provided a half-price CSA coupled with tailored nutrition education and cooking tools to low-income families with children in rural and micropolitan communities in four states. This randomized controlled trial found that participation in F3HK for just one summer improved fruit and vegetable intake among caregivers by 1 cup and increased household food security by 13 percentage points.
