Droughts occurring every year over the India different parts have great impacts on human society, nature, and the global economy for example in declining crop yields, reduction of water supplies, and concerned vegetation. The main objective of this research paper is to Normalized Difference Vegetation Index (NDVT) to augment agriculture drought-monitoring techniques. The NDVI is used, in this case, by comparing the deviation of the current satellite observation from the historical average within a certain time period, or window, of interest. In rainfall dependent agriculture production areas, seasonal rainfall variability is reflected in both highly variable production levels and in the risk livelihoods of local farmers. Remote sensing and Geographical Information Science has been used to monitor agro-climatic conditions, vegetation cover, and to estimate crop drought in study area. The study was conducted with 10 years (2001-2011) of Advanced Very High-Resolution Radiometer (AVHRR) satellite images NDVI information has been used in vegetation monitoring, crop yields assessment, and forecasting. The results show that in several Tehsils regions, there is a statistically significant correlation between Crop production and rainfall and the water balance parameters, indicating an unacceptable performance in detecting crop drought stress conditions. The impact of dry periods on crops is clearly observed in both arid land and wet land, and it is found that arid land presents a higher sensitivity. | | Keywords : | | |
