Advanced Very High Resolution Radiometer (AVHRR) 8-km Normalized
Differential Vegetation Index (NDVI) data and Moderate Resolution Imaging
Spectroradiometer (MODIS) 16-day 250m NDVI data product were taken to analyse
vulnerability of Indian agriculture to climate change impacts. Predicted higher temperature
and altered rainfall patterns accompanied by extreme weather events would impact
vegetation growth in natural forest, open scrub, agricultural land and plantations. NDVI
derived from 2-band information (Red & Near-infra Red) of multi-spectral imagery of
NOAA-AVHRR (1982 to 2006) and from MODIS (2000-2010) were analyzed. CV of Max
NDVI from 15-day composites for the total length of study period was used to assess
agricultural vulnerability and results were corroborated with Standard Precipitation
Index (SPI). AVHRR time-series data helped to identify vulnerable areas at regional
scale i.e., agro-ecological sub-regions (AESR) while MODIS data products helped to
identify vulnerability at sub-district level. It is estimated that over 263.74 M ha area in
the country may be vulnerable to climate change of which over 81.3 M ha are located
in arid, semi-arid and dry sub-humid regions. Study indicated that over 12.1 and 1.81
M ha of Kharif cropland would be mildly and severally vulnerable respectively, while
6.86 and 0.5 M ha of Rabi cropland may be adversely affected in a similar manner. Of
the remaining agricultural lands, 29.93 and 5.24 M ha would also be vulnerable similarly.
