This rapid appraisal study compares the actual and projected performance of a large, rice monoculture irrigation project in the humid climate of the Caspian Sea in Iran. The uniqueness of this project is the co-existence of East-Asia rice farming techniques with advanced technologies of automatic water control found generally in the Mediterranean countries. The paper emphasizes the need to do field tests at the design stage in order to make realistic assumptions on water efficiency and deep percolation. The study confirms that the advanced water control technologies are appropriate for small farm irrigation projects in the humid tropics, a conclusion often debated among experts. The Guilan project now provides some evidence to support that conclusion.

This study assessed the economic value of rice irrigation water in four key rice-producing provinces of Iran: Guilan, Mazandaran, Khuzestan and Fars. In this respect, the production function approach and cross-section data of 2014–2015, collected from paddy farmers in each province, were applied. In this research, two approaches were used: (i) determining the economic value of irrigation water after omitting outliers and extreme observations (first approach); (ii) determining the economic value of rice irrigation water using relevant observations that match the yield–input consumption trend equation (second approach). The results of the first and second approaches showed that Guilan province was ranked first in terms of economic value of rice irrigation water with average economic values of US$0.47 and 0.53, Mazandaran ranked second with average economic values of US$0.35 and 0.32, Khuzestan province ranked third with US$0.17 and 0.16 and Fars province ranked fourth with US$0.09 and 0.09, respectively. Therefore, it is recommended that farmers cultivate rice in the two first provinces that enjoy enough water and, also, in the two last provinces limit the scope of their cultivation because of water scarcity. This methodology can be employed in other regions to prioritize areas suitable for rice cultivation.
