Concept:Harvest losses are most directly linked to the poor condition of facilities used after harvesting.
Explanation:During the harvesting period, large quantities of produce are brought in at once.
If storage and processing facilities are inadequate, the produce cannot be preserved or handled quickly.
This leads to spoilage, rotting, insect attack, and physical damage.
Transport issues, poor extension services, and weak policy implementation can contribute to waste too.
However, the main and immediate cause of wastage at harvest time is the lack of proper storage and processing facilities.
