Pulicat Lake is the second largest brackishwater lake in India and house for
migrant water birds and breeding ground for several species of birds and marine
organisms. Remote sensing, Geographical Information System (GIS) and Global
Positioning System (GPS) were used to assess the changes in the land-use
pattern in and around the Pulicat region. Digital image processing of the IRS 1C LISS-III images (2005) and Survey of India toposheets (1967) were used to
derive the land-use pattern and classified images were analysed using GIS for
detection of changes. The results indicated that the Pulicat lake water spread
area and lake mud area have been reduced from 28758.63 ha to 26848.36 ha
and 22841.67 ha to 21627.27 ha during 1967-2004 respectively. The
development of aquaculture was estimated to be 382.77 ha along the lake
channel and change detection analysis revealed that aquaculture farms were
mostly converted from agricultural lands. The irrigation tanks have reduced by
2629.72 ha in between 1967-2005 and this was silent and unnoticed degradation
which needs immediate attention and prompt action. Though the Pulicat Lake
was in the limelight in view of anticipating aquacultural development, the lake
was not affected due to aquaculture and this study revealed unambiguous
visual information on the alarming levels of human-induced environmental
degradation of tanks.
