The document discusses food wastage and malnutrition. It defines food wastage as food loss during agricultural production, harvesting, and processing or food waste from consumers. A major cause of hunger is food loss during harvesting and processing in Africa due to infrastructure issues like lack of roads, rail, power and cold storage as well as bureaucracy, corruption, theft and lack of data. Reducing post-harvest loss by 20% could help close the calorie deficit and potentially save lives. Collaboration between producers, technology companies, supply chain partners, authorities and NGOs is needed to address the problem.
