Ending Wasted Food for Climate: Agrarian Movements at UNFCCC
Clusters: Policy
PIs & SP Involved: Graddy-Lovelace

Dominant agri-food systems are key drivers--and victims--of climate crisis, with vast carbon dioxide, nitrous oxide, and methane emissions. Finally, food and agriculture feature prominently at the UNFCCC global climate negotiations. This paper, in a special feature on collaborative event ethnography of COP27 for the journal Climate & Development, traced the role of food and agriculture topics, and agrarian justice movements at COP27 (and COP28). We tracked how wasted food mitigation could have garnered global consensus around methane drawdown pledges, but has not yet.

Food Agency and Food Waste in the DMV
Clusters: Community
PIs & SP Involved: Claus, Dowdy

This project is based on qualitative, ethnographic fieldwork in Washington, DC to explore various aspects of food access, food agency, and food waste, primarily focusing on farmers markets and community gardening in the city. The questions of interest revolve around the consumers’ perception of farmer's markets in reducing food waste, increasing agency, and addressing food insecurity in the DC area.

We started this cross-disciplinary project with researchers in public health and ideally would like to be able to return to transdisciplinary collaborations after we have undertaken ethnographic fieldwork.

Food for Thought: Why Waste?
Clusters: Education
PIs & SP Involved: Jardine, DeBruin, Beran

This created a complete academic course and embedded educational resources that institutions can use to teach students about wasted food, aligned with inquiry-based, high impact course design. It engages students with issues of sustainability, social justice, and convergence research more broadly. The course could potentially "plant the seed" in the minds of undergraduate students to focus on wasted food as a career or area of graduate study. The project also researches impact on students' learning, impact on instructors' teaching, and the process of developing a course informed by a large research network.

N/A
Food Matters Evaluation
Clusters: Community, Rescue
PIs & SP Involved: Richardson, Neff, Harper

This project will develop an evaluation of interventions implemented by multiple local governments through the NRDC Food Matters Program. It will seek to understand intervention impacts across different local government typology settings, and gain insights to support adapting to context. The current iteration of the evaluation plan involves using semi-structured interviews and reported data from participating cities to characterize impacts of the Food Matters interventions on a) executive leadership activities, b) provision of incentives or technical assistance, c) public engagement and d) data collection or analysis of food rescue activities.

The plan will be co-developed in partnership between RECIPES researchers and NRDC staff. After the team defines the purpose further, but before the project is fully established, they will open the invitation more broadly for RECIPES collaboration, to advance further convergence.

Ways FoodImage App Might Be Useful for Community Cluster Projects
Clusters: Community, Data
PIs & SP Involved: Apolzan, Martin, Roe, Li

The purpose of this study is to evaluate the utility of an app-based method for quantifying food waste in controlled conditions, as well as free living conditions. The app is designed to quantify food waste that occurs when food is prepared, eaten, and discarded when refrigerators and cabinets are cleaned out. The app also determines the disposition of food waste or where the waste goes (e.g., fed to pets, garbage/landfill, sink disposal, compost bin, etc.). Finally, the app quantifies food purchases as well, allowing us to evaluate if pricing and/or healthfulness in which food is acquired (e.g., buying things in bulk) is associated with waste. The app and associated methodology have other applications and we are eager to overcome the limitations of the method, which primarily revolved around scalability. We are pursuing technology (e.g., semi-automated computer imaging) to do so.
