Satellite data based Normalized Difference Vegetation Index (NDVI) was used to assess state of agriculture in Andhra Pradesh. Public domain NDVI data from NOAA-AVHRR (1982-2006) was used to analyse LGP variations in various agro-ecological sub-regions (AESR) in Andhra Pradesh. Study indicated that there was an increasing trend in LGP in all AESR in the state. However, drought occurrence like in 1994-95 showed a sharp decrease in LGP across the state. Study indicated that agriculture was vulnerable
in AESR 3.0, 8.3 and 6.2 covering Anantapur, Chittoor and large parts of northern Telengana and relatively safe in AESR 7.2 covering southern Telengana and 6.3 including parts of Adilabad. Agriculture would be marginally vulnerable in AESR 7.1 covering Kurnool and Kadapa and in 7.3 and 18.3 covering coastal districts of Nellore, Prakasam, Guntur and Krishna.
