improving food security in iran: quantifying post-harvest rice losses

Purpose: food is a basic need for human life. ensuring food security requires guaranteeing adequate food availability, accessibility, and utilization along with the sustainability of the food system. food availability can be improved by decreasing food losses. the goal of this study is to document the causes and quantify the amount of losses in iran’s rice supply chain. research method: a cross-sectional survey method was used to collect data through interviews with some actors of the rice production chain operating in mazandaran province, qaemshahr, in 2015, to approximate percentage weight losses at the different stages in the supply chain. main findings: the rice losses are estimated to be about one-third of the production that could feed 18 million people per year. on the other hand, the rice losses imply an economic loss of 1,403 million u.s. dollars, annually, and losing some scare resources, such as water, in iran. limitations: it is not easy to apply the ways to collect the useful and more accurate data in order to find the most important reasons of food losses for each stage and process of the food supply chains. originality/value: it was found that it is necessary to invest in the marketing systems, renew the supply chain and improve knowledge of the actors of the rice chain -from producing to consuming- in iran’s rice system to reduce the physical and economical estimated losses of rice.
