Coastal areas provide fertile soil and suitable climatic condition for agriculture. Coastal agriculture renders significant contribution to the livelihood and economy of the local communities and also to the nation’s food production. Recent years witness visible loss in the coastal agricultural areas due to increasing climatic and non-climatic factors. Besides climatic stress, non-climatic factors such as growing population, land conversions and other economic activities induce dramatic changes in the extent of agricultural lands especially along the coast. This study attempted to assess the impact of the non-climatic factors on coastal agricultural areas of Nellore in Andhra Pradesh. The period of assessment is from 1990 to 2020 using temporal satellite images. The study indicated a loss of about 28% of arable lands within the assessed period. Using the past trends, the status of the agricultural lands in 2030 is, Geographical Information System (GIS) and spatial modeling techniques are used for the assessment.
