Abstract
Drought mainly happens due to lack of rain or below normal rainfall in a region, and it causes water shortage for agricultural crops and is associated with other climate-related factors. This chapter aims to assess the mete- orological and agricultural drought risk over the Bundelkhand region (central part) of India, comprising seven districts of Uttar Pradesh and six districts of Madhya Pradesh states, through the remote sensing-derived Normalized Difference Vegetation Index (NDVI), Vegetation Condition Index (VCI), and meteorological-based Standardized Precipitation Index (SPI). Daily rainfall data from National Oceanic and Atmospheric Administration (NOAA) and Climate Prediction Center (CPC) have been integrated with satellite-based vegeta- tion and in situ crop yield data sets. The SPOT-VGT NDVI-based time series data for rainfed crop seasons 2002-2013 were used to assess the long-term vegetation condition correspondence to meteorological drought indices. The satellite-based drought indices and meteorological data showed positive results for assessing the spatiotemporal pattern of drought over the study area. © 2020 John Wiley & Sons, Inc.
