Climatic variations effects on yield and related welfare of two groups of agricultural crops in Khuzestan province

The aim of this study was to evaluate the possible changes of yield and related welfare of two major groups of cereals and vegetable crops as a result of two climatic variables (rainfall and temperature) variations in Khuzestan province. For estimation of crop response production function of selected study crops, meteorological data including rainfall, minimum temperature, maximum temperature and relative humidity of 13 stations across the province for the years 1991 to 2019 were collected. Crop response production functions for different climate zones of the province were determined and possible effects of climatic variation on producer / consumer welfare were assessed. According to the results, the welfare of the cereal crops, the producer welfare surplus is higher than the consumer welfare surplus. A decreasing trend in welfare was observed under climate change scenarios. Also, the obtained results of projected welfare of the vegetables crops showed that the consumer welfare surplus is higher than the producer welfare surplus. In general, the welfare surplus of cereals is higher than that of summer vegetable crops and hence as a adaption strategy, cereal cultivation may be recommended.
