University of South Florida, Hillsborough County and City of Tampa Office of Emergency Management, lemonGRAFT Inc., and several organizations in the food sector will work together to address food security during natural disasters by developing a GIS-based decentralized digital platform through special consideration of socially vulnerable populations. The platform will adopt GIS and web mapping to crowdsource real-time information, identify vulnerable neighborhoods, and match the surged food demand with local food growers and suppliers through the sharing economy business model. This project will help the community of the Tampa Bay Area by providing a robust solution to healthy food access for pre-disaster preparation and mitigation alternative, which can be scaled up to the rest of the United States.
