S. Lele et al., MESOSCALE ANALYSIS OF FOREST CONDITION AND ITS DETERMINANTS - A CASE-STUDY FROM THE WESTERN GHATS REGION, INDIA, Current Science (Bangalore), 75(3), 1998, pp. 256-263
We present here preliminary results from a meso-scale analysis of fore
st condition in a region of the Western Ghats of India where the natur
e and extent of forest degradation and its causes have been intensely
debated. We use 1:35,000 scale aerial photographs of 1973 to generate
a detailed land-cover map, and overlay legal forest regime and village
boundaries to associate forest condition with the rights regime and v
illage-level socio-economic data. The differences between our land-cov
er map and an official forest cover map for that region are significan
t, Although denudation is expectedly higher in areas accessible to loc
al communities than in state-controlled areas, both the absolute level
s and the relative differences are much lower than indicated in the of
ficial map or earlier studies. Denudation in private access forests ap
pears to be significantly influenced by the cropping patterns in the v
illages. We discuss the concerns in applying remote sensing and geogra
phic information system techniques to densely populated and diversely
utilized forests, highlighting the need for greater access to aerial p
hotographs, the appropriate characterization of forest condition, and
attention to slope information and positioning errors.
