Small-scale coolrooms & cool transport for limited resource farmers


This poster focuses on postharvest cooling, originally from the Horticulture Innovation Lab's (formerly Horticulture CRSP) inception workshop in May 2010, presented by Michael Reid, James Thompson, et al. From the poster:

Postharvest losses - low hanging fruit

In numerous studies, including the recent Gates Foundation survey conducted by WFLO and UC Davis, postharvest losses of perishable horticultural crops in the developing world have been estimated to average from 30 to 50 percent. Reducing this loss in value is an obvious opportunity for the Horticulture Innovation Lab (then CRSP) to have a significant impact on the livelihood of limited resource farmers.

Cool temperatures - key to reducing losses

Low temperatures reduce metabolic changes, reduce water loss, slow the spread of postharvest diseases and limit responses to ethylene. In the developed world, refrigeration is universally recognized key to successful marketing of perishables. Temperature control is even more critical for produce in the developing world. Ambient temperatures often are above 30°C, which can result in deterioration rates more than 20 times those at 0°C, the proper storage temperature for many high-value horticultural crops.
