Zoning of climate changes rate base on agriculture approach in future climatic period (case study Khorasan Razavi province)

The trend analysis of the historical data and the output of Global Climate Models (GCMs) show that climate change is inevitable. According to the current trend, world population would be increased twice during in the one hundred futures. Climate change has most important in agriculture aspect; because the agricultural section provides food for people and climate change influence the safety food. One of the climate changes is boundary replacement of forest and agricultural areas toward north. According to the report of Intergovernmental panel of climate change (IPCC), the most important results of climate change will be as follow: - Intensifying climatic cricis; -Warming of high latitudes, - Decreasing of available water resource and - Development of monsoon rainfall toward the poles. Thus, the clear characteristic of climate change should be explored in studying critical phenomena spatially in agriculture which is more important. In this research, the changes of eight indices effective on agriculture have been investigated for future climatic period (2010- 2039). In the next step, spatial analysis has been done for anomaly of each index as separately and together.
