Perishables crops are the crops which have high moisture content and short shelf life. They generate income since it can be used to achieve zero hunger and food security. However the major problem with perishable crops due to high moisture content, short shelf life and change quality parameters particularly storage. According to most of research and review shows, approximates 40-50% perishable crops loss in the supply chain at globally level. In Ethiopia also, postharvest loss of perishable crops is 50% due to lack of appropriate post-harvest handling practice and inappropriate storage technologies. In order to reduce post-harvest loss of perishable crops and enhance food and nutrition security, the of roles of low cost and improved storage technologies is great. Storage technologies like Low cost storage can be beneficial for farmers needing a small-scale storage system. On other hand, improved storage technology includes refrigerated storages like cold storages, controlled atmospheric storage, modified atmosphere storage, and hypobaric storage play great role to reduce post-harvest loss of perishable crops. This technology reduces post-harvest losses of perishable crops by controlling temperature, concentration of gases and relative humidity of the storage area. Therefore, the aim of this review paper is to review studies made by several researchers and reviewers on the roles of improved storage technologies in post-harvest loss reduction of perishables crops and enhances food and nutrition security. So to alleviate post-harvest loss of perishable crops and to solve problems of food and nutrition security, using improved storage technology is very important and determinant.
