A study on the land degradation in the
upper catchment of river Tons, a tributary of Yamuna
river, in Uttarkashi district of the Uttarakhand state
was carried out using on screen visual interpretation
of IRS LISS-III + PAN merged data. The study area,
which is highly mountainous, includes Govind
Wildlife Sanctuary and National Park. Vegetation
cover, slope and erosion status were used as criteria
for delineation of four major land degradation
categories viz., undegraded, moderately degraded,
degraded and severely degraded. The study showed
that more than 50 percent of the study area is
covered with snow and grasslands. The moderate to
severely degraded area worked out to be 42.4 percent

of the total area. The 32.8 percent of area was found
to be moderately degraded, followed by degraded
(6.63%) and severely degraded (2.88 %) areas. The
depletion of vegetation cover on mountainous
terrain and subsequent cultivation without proper
protection measures is the reason for severe soil
erosion and land degradation. In view of the existing
land degradation situation, the catchment requires
immediate treatment on priority basis for sustenance
of agriculture and wild life. It is expected that these
measures will reduce the silt load in the river Tons
and eventually in river Yamuna.
