Urban Food Nexus: A Smart Community-Driven Food Redistribution and Crisis Management System

Abstract

Urban areas across the globe face a paradoxical challenge of food surplus and food scarcity existing simultaneously. While restaurants, households, and food hubs often generate excess food that goes to waste, vulnerable communities experience food shortages due to inefficient distribution systems. This imbalance highlights the need for an intelligent and community-driven solution that can bridge the gap between surplus and deficit. The proposed system, Urban Food Nexus, is a web-based platform designed to facilitate real-time food redistribution by integrating food hubs and community-generated crisis signals. The system leverages a centralized dashboard that aggregates data from multiple food hubs, including government storage facilities, non-profit organizations, and community gardens. It dynamically tracks food stock levels, storage capacity, and distribution status. Additionally, it incorporates a user-driven reporting mechanism where individuals can report food shortages (shortfalls) or excess food (surplus) in their locality. These reports, termed as “Community Signals,” are prioritized based on urgency levels, enabling efficient decision-making.The platform is built using the Django framework, ensuring scalability, modularity, and security. The system intelligently matches surplus hubs with shortage locations, ensuring optimal resource utilization. It also provides analytical insights such as total stock percentage, number of crisis signals, and surplus occurrences, helping stakeholders understand real-time food distribution dynamics. A key feature of the system is its ability to handle real-time updates and maintain transparency in operations. By marking signals as addressed upon successful resource allocation, the system ensures accountability and avoids redundancy. Furthermore, the inclusion of urgency levels helps prioritize critical situations, ensuring that high-risk areas receive immediate attention. The proposed solution addresses major limitations of traditional food distribution systems, such as lack of coordination, delayed response times, and inefficient resource utilization. By integrating community participation with technological infrastructure, the system fosters a collaborative approach toward food security. It not only reduces food waste but also strengthens urban resilience against food crises. In conclusion, the Urban Food Nexus system presents a scalable and efficient model for addressing urban food distribution challenges. Its community-centric design, combined with real-time monitoring and intelligent allocation, makes it a valuable tool for smart city initiatives and sustainable development goals. The system has the potential to significantly reduce food wastage while ensuring equitable distribution, thereby contributing to a more sustainable and food-secure urban ecosystem.
