        Wheat is one of the strategic agricultural products which provides one of the most basic nutritional needs of human societies for Iran and the whole world. Having the right statistics and information of the lands under wheat cultivation and estimating the amount of their production in one crop year can help the planners of agriculture and industry to manage the production and consumption of the mentioned product as effectively as possible. One of the tools that can calculate the level of wheat cultivation in the shortest time and with low cost and appropriate accuracy is the science and technology of remote sensing. In the present study, using a supervised classification of images from several time of Sentinel 2, the area under wheat cultivation and its production rate for the 96-97 crop year has been estimated. Supervised classification with the overall accuracy of 80% and a kappa coefficient of 0.8 has acceptable and suitable results for the identification and separation of wheat from other agricultural crops.

        Today, climate change poses an environmental challenge to climate scientists, environmentalists, and politicians and governments. Whatever the scientific and theoretical view of climate change, even as a given phenomenon, one must be concerned about this. Because taking precautionary measures will make us safer than possible harm. In this regard, this study aimed to reveal the effect of climate change on dryland wheat calendar (Chamran cultivar) as a cultivated species in Khuzestan province. Precipitation data, minimum and maximum temperatures were sorted during the 1980–2010 climate. And after normalizing the data into the LARS-WG software environment .And its output was simulated by the LARS-WG model under the A2 emission scenario for the 2015-2045 climate period for the four parameters of minimum temperature, maximum temperature, radiation and precipitation. HADGCM2 model data from MarkSim output is also used for the next period (2030-2015) and (2030-2045). The results of this study showed that in the two 15-year periods 2015 to 2030 and 2030 to 2045 the minimum and maximum temperatures will increase according to all pessimistic and optimistic scenarios. This increase in March to April coincides with the harvest period more than other months. Precipitation in January, December and March will decrease in all scenarios. This decline will be more noticeable especially in the forecast period of 2015 to 2030 than in the forecast period of 2030 to 2045. In contrast, in November, February and April there will be an upward trend in all scenarios. Based on the combination of the two elements of temperature and precipitation predicted for the next two periods, all planting periods will have a harvest of 10 to 15 days. Manuscript profile
