This paper attempts to provide information for
policymakers and soil conservation planners in the form of
district-wise soil erosion risk (SER) maps prepared for the
state of Telangana, India. The SER values for each district
were computed by extracting the information on grid-wise
soil erosion and soil loss tolerance limit values existing on
the country-scale in a GIS environment. The objectives of the
study were to (i) identify the areas of the state with a high
erosion risk, and (ii) identify areas with an urgent need of
conservation measures. The results reveal that around 69 %
of the state has a negligible risk of soil erosion above the
tolerance limits, and does not call for immediate soil conservation
measures. The remaining area (2.17 Mha) requires
conservation planning. Four districts, viz. Adilabad, Warangal,
Khammam, and Karimnagar are the most risk-prone with
more than one-quarter of their total geographical areas showing
net positive SER values. In order to obtain a clearer
picture and categorize the districts based on their extent of
vulnerability, weighted erosion risk values were computed.
Adilabad, Warangal, and Khammam were identified as the
worst-affected districts in terms of soil erosion, and therefore
are in need of immediate attention of natural resource
conservation.
