Analysis of the effects of change in cropping pattern due to drought on saffron production in rural areas of the Zebarkhan district villages

Selection of a given cropping pattern can have serious results on the farmers’ life and rural society because of the multi dimensionality of agriculture. However, in many cases, farmers are inclined to change the cropping pattern because of changes in natural situations, changes in demand and consumption, etc. One of the most important and effective factors of change cropping pattern amongst Iranian farmers in recent years is the drought problem. One of the more current cultural method changes in the Khorasan region is inclination to saffron cultivation that can have various economic, social and environmental effects. Thus, this research paid attention to the investigation of changes from cultivation method from drought to the economic, social and environmental dimensions of saffron production amongst the villagers of the Zebarkhan district of the Khorasan Razavi province. Analytical-description methodology was used for this purpose. Data collection was done using the library- field methodology with researcher’s questionnaire whose narrative is 0.78 according to Cronbach's alpha method. Therefore, by using the Cochran formula with the intended level of 0.05, 142 farmers have been selected by available sampling method that have changed their cropping pattern to saffron production because of water shortages and drought. Then, their ideas were analyzed considering cases of economic, social and environmental effects of cropping pattern change to saffron production. The results showed meaningful changes in all research indices except for increase of cultivation surface area. Moreover, the most important changes of cropping pattern and switching over to saffron production have been identified using the Shannon entropy weighing method. In addition, the shown the revealed with continuation of differences of the changes in cropping pattern of saffron between the various villages were analyzed by using the multi-index TOPSIS. Finally, it was shown that the Harim Abad village with a score of 1 for the coefficients of each of the three dimensions has been selected to have been most affected by changes in cropping pattern while the Kalateh Soltani village with a coefficient of 0.183 has been the least affected
