Cut Post-Harvest Losses for Smallholder Farmers by 40%

Post-harvest loss is one of Africa's most documented and least solved problems. Tomatoes rot on the road to Lagos. Yam deteriorates in storage. Maize goes mouldy before the middleman arrives. Smallholder farmers absorb these losses quietly. Your challenge is to design an intervention that reduces post-harvest loss for one specific crop in one specific region of Nigeria. The intervention can be a storage solution, a market linkage model, a cold chain design, a processing idea, or a combination. Submit a solution document covering: the specific crop and region, the loss point you are targeting, your proposed intervention, the cost to implement per farmer, and evidence (or a strong argument) that it will work. Judging criteria: 40% impact potential, 30% feasibility and cost, 20% specificity, 10% quality of evidence.
