Abstract


Scientists around the world have shown impacts of the climate change in agriculture. The study of impacts climate in agriculture is very important for different areas, human, economic, hydrology, social, environment, etc. The aim this study is to analyze the spatial-temporal variation of agriculture due hydric reposition on semiarid region of Brazil. In this study we used Landsat image for estimate NDVI – Normalized Difference Vegetation Index and method of Thornthwaite and Matter for estimate water balance. The results of this study show that knowing the amount of water that is stored in the soil during rainy season is very important to specify the conditions of the agriculture in this year. Finally, it is possible to predict the conditions of the agriculture using climatic water balance and vegetation indices obtained satellite images of the rainy season.


Keywords
