Assessment of Three Decade Vegetation Dynamics in Mangroves of Godavari Delta, India Using Multi-Temporal Satellite Data and GIS

C. Sudhakar Reddy and Arijit Roy

Abstract:
The present study assess spatial change in the mangrove cover over the last three decades in the Godavari delta, using Landsat MSS, TM, ETM + and IRS P6 LISS III images. From 1977 to 1988, the mangrove vegetation cover had a drastic change and lost about 24.6 km2, which was mostly recovered during the next period (1988-2000). Over the entire three decade period the net change was negative, which was quantified as 8.8 km2. It is also observed that plantation cover shows increase of additional 7.6 km2 during 1977 to 2005. In Coringa Wildlife Sanctuary the net change was positive with an increase in mangrove area of 107.2 to 114.2 km2. The study concluded that mangrove loss is mainly due to encroachment by aquaculture, agriculture and coastal erosion. The gain in the forest cover is attributed to the accretion, restoration and protection.
