Abstract

The availability of on-farm storage and processing is a critical challenge facing small farmers, which hinders agricultural productivity. Thirty per cent of the food produced globally is lost after harvest, with the proportion being exceptionally high in low- and middle-income countries due to a lack of on-farm handling and storage facilities. Conventional cold-storage solutions have not taken off at the smallholder level, mainly due to a lack of availability and access to reliable grid electricity. Therefore, off-grid decentralized solar-powered cold-storage units can play a vital role in preserving the produce at production sites and enhancing livelihood and rural development with a minimal carbon footprint. To maintain low temperatures at every step of the agricultural value chain, known as the ‘cold chain’, several technology vendors aim to improve the shelf life and user benefit. Small-scale farmers, which account for two-thirds of all food losses, are another group they focus on. This study examines the existing situation, importance and potential opportunities of decentralized cold-storage systems for fresh fruit and vegetables. In addition to economic, social, technological and environmental limitations, this study examines the triumphs and challenges of incorporating solar-energy-powered cold storage into developing communities. Although the private sector, NGOs and some government agencies are working to promote decentralized cold-storage facilities, relatively little has been done so far to have a significant influence on post-harvest losses and food security. There are still knowledge gaps on decentralized cold-storage facilities. The primary operational constraint is the economic situation of end users and the lack of financing alternatives for smallholder farmers.
