Abstract
Interpretation of multi-date satellite imagery has revealed changes in land use/land cover pattern in the Godavari deltaic region during the past 26 years. The area under intensive agriculture has increased from 1459 to 3500 km2 and the extent of wetland from 368 to 648 km2 during the period 1973-1999, while the seasonal fallow has decreased by 2321 km2. Analysis of the climatic data of 1970-1998 from different stations covering the entire 5100 km2 area of the delta indicated that the day time temperatures have decreased by 0.2° C to 0.7° C, while the night time temperatures have increased by 0.5° C to 0.6° C during the past three decades. At the same time the rainfall has increased by about 75 to 479 mm. These trends in the climatic parameters arc attributed to the increased vegetation cover and wetland extent in the Godavari deltaic region.
