Researchers Urge Investment to Curb Post-harvest Food Losses

Approximately one-third of food produced for human consumption is lost or wasted globally, highlighting the need to improve post-harvest management alongside efforts to increase agricultural production. A study reviewing 324 research papers identified losses at every stage of the supply chain, from harvesting and handling to transportation, storage, processing, and marketing. Researchers identified poor infrastructure, climate pressures, inadequate financing, and limited market access as major contributors to these losses. They recommend standardized measurement methods, investment in rural roads and storage, affordable technologies, farmer training, and accessible credit as potential solutions. The study found that, without interventions, estimated losses reached about 27.7% for cereals, 35.1% for vegetables, 25.8% for fruits, and 42.9% for roots and tubers. With appropriate interventions, including improved handling, airtight storage, cold-chain infrastructure, and better packaging, estimated losses fell to roughly 8.2% for cereals, 7.3% for vegetables, 6.2% for fruits, and 11.5% for roots and tubers. Accordingly, the researchers argue that integrated investment across entire food value chains can strengthen food security, improve farmers’ incomes, and support climate resilience across the Global South.
