estimating the economic value of the lost water due to wastes of agricultural products (irrigated crop and garden) from the harvest to before taking

the methods, the technology, the production patterns, the equipment, the capacity of the domestic infrastructure of each country, the mechanism of market capacity, market chains, releasing and distribution channels of agricultural and food product, purchasing patterns, and food consuming of consumers affect on the wastes of food products. regardless of the level of economic and social development of each country, the food wastes should be on the lowest level in the country. in term of resources losses in the agricultural sector, the food wastes are important, especially water input is considered as rarest input in this sector. therefore in this research, regarding the estimating the amount of the waste products of agriculture (crop and garden) in the 2013-2014 crop year, we calculate the amount of wastes and economic value of water. we utilize the fao definition in 2011 for estimating the wastes. in order to achieve the objectives of the research, at first, the amount of wastes products of agriculture for 17 major crop products and 6 major garden products have been determined. these products contain the most water. followed by the results, the results have been expanded to all crop and garden irrigated products. based on the results of the study, the amount of lost water due to waste products of agriculture is 9.3 billion m3, equivalent to about 45 percent of the volume of water stored behind the dams in the water year 2013-2014. the economic cost of lost water due to wastes is also 92297.1 billion rials.
