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 123 RESEARCH ARTICLE 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. Not Available |
