Global studies on vegetation trend analysis reflected that the South Asia is one of the most remarkable regions in its widespread area of increasing photosynthesis as captured by the satellite data and this extensive greening is happening mainly because of agricultural activity.A trend analysis study specially taking the croplands in to consideration would contribute to an improved understanding of the vegetation growth pattern in this region and its drivers.Therefore an effort has been made to investigate the trends and patterns in vegetation greenness if irrigated and rainfed croplands distributed in the study area.Here we investigated both spatial and temporal patterns of crop vegetation growth over last 32 years(1982-2013)with the help of multiple satellite time series data.Seasonal(summer monsoon and winter monsoon)NDVI variation also has been examined.The AVHRR GIMMS normalized difference vegetation index(NDVI)has been used as proxy for vegetation growth.Our study exposed that major greening is occurring especially due to increase in irrigated croplands productivity during winter monsoon season.Almost 48.41%of total cropland(20.13%from rainfed area and 28.28%from irrigated land)pixels are showing significant change in last 32 years.Increasing pixels are spreading more over irrigated lands and trend is very much significant than rain fed areas.27.02%of the irrigated land have increasing and 1.25%have the decreasing trend where as in rainfed land 16.87%and 3.26%area having the increasing and decreasing trends respectively.In total croplands greening trend is widespread in winter monsoon season(48.17%)rather than in summer monsoon season(31.59%).Interestingly,the trend slope for irrigated is much higher in winter monsoon than the summer monsoon season,indicating the important role of landuse practice.
