Analysis of gross value of irrigated agricultural products in Qazvin province based on GVIAP index

GDP is one of the most important economic indicators at regional and national levels. Regarding climatic conditions, in most regions of Iran, production without irrigation is not economic. Hence, the analysis of irrigation sector share in total agricultural production and estimation of economic value that is associated to irrigation process is necessary. In this research, the gross value of irrigated agricultural products in Qazvin province (garden and annual crops) was calculated based on the methodology provided by the National Center for Statistics of Australia. So, irrigated and rainfed products were analyzed during the period from 2002 to 2016. The results showed, gross value of irrigated agricultural products of province in 2016 was 29491 billion Rials and equal to 95 percent of the total gross value of agricultural products. Irrigated grapes, wheat and tomatoes were rank first to third crops based on GVIAP index with 20%, 8%, 7% of gross value of irrigated agricultural productions in province. Also, based on the amount of consumed water by the products, the share of each cubic meter of irrigation water in the gross value was calculated 15259 Rials. Analysis of water use pattern showed that alfalfa with 5% share in gross value has the highest share in water use pattern (18%). In order to mitigate the economic consequences of water shortage in the agricultural sector, consideration of the GVIAP index and water use pattern can be recommended.
