Abstract
India is an agriculture dominated country, which requires well managed irrigation system across the river basins to benefit farmers. Narmada basin is one of the largest basins in India, having a large-scale implementation of irrigation network in the last few decades. A study of vegetation dynamics, along with associated environmental and surface parameters, is required for the sustainable development. However, only a few studies focused on the basin level and sub-basin level vegetation dynamics. The present study is focused on dynamically varying vegetation over spatial and temporal scales for Narmada basin and its sub-basins using MODIS normalised difference vegetation index (NDVI) data (2000-2021). Changes were observed in the fractional vegetation cover using MODIS vegetation conmicrowave remote sensing based derived soil moisture data and MODIS aqua day and night land surface temperature data. Time-series analysis revealed the increasing trend of NDVI at basin level and majority of subbasins. An increase in fractional vegetation cover associated with improved vegetation condition was observed during the last two decades (2000-2020). Change in cropping pattern was observed over wide area across the basin, showing increase in the number of months and night temperature difference. The present study fills the gap area in the existing literature describing changes observed in the vegetation dynamic pattern over Narmada basin after the implementation of largescale irrigation network during last two-decades.
