Abstract

Climate changes directly affects agricultural production and on the other hand, the agricultural sector is inherently sensitive to climatic conditions, which has led the agricultural sector to be one of the most vulnerable sectors to the global climate and weather effects. Therefore, rural areas and their livelihoods have a direct relationship with climatic variables in arid and semi-arid regions. So, the purpose of this study is investigate the trend of changes in some climate parameters and its effect on agricultural activity status in North Khorasan Province. Therefore, in order to estimate the expected results, the official and recorded data of the country's Meteorological Organization (years 2014-2004) as well as the general census of agriculture related to the years 2003 and 2014 have been used. The most important results of this study are the increase in average annual temperature and average annual rainfall (from 287.4 mm in 2004 to 205.5 mm in 2014). In this regard is visible reducing the number of agricultural utilities; reducing the area of arable lands and landscaping; decreasing the per capita of agricultural land; a significant reduction in crop lands (the highest percentage of changes belonging to the cropland land area with -20.8 percent and the area of rain gardens with -23 Percent); Per capita land use (from 5.1 hectares per exploiter to 4.5 hectares). Also, the percentage of changes in the utilization of all crops other than rice has been negative. the production of wheat, barley and beans was also significantly reduced.
