hazards, i.e., fl ash fl ood, river-line fl ood, erosion, non-seismic land slide
in the monsoon period and drought hazard as drying up of natural water
springs and decreasing streams discharge in the non-monsoon period. An
attempt has been made in the present study to assess the trends of land-use
pattern in a fragile watershed located near a seismic and tectonically active
region of the Himalaya. The watershed lies between the latitude 29°24'09”-
29°30'19”E and longitude 79°17'53”-79°25'38”N in the North west of
Nainital Township (Fig. 11.1). The region encompasses a geographical area
of 69.06 km
2
between 700 m and 2623 m altitude above mean sea level. The
total population of the watershed is 9250 people, which includes 16 villages.
The population density is 76.02 person/km
2
. About 95% population of the
total population depends on agriculture and forest resources but the forest
cover is decreasing 0.36 km
2
per year and the agricultural production is also
decreasing due to climate change and drought hazard (Rawat 2013). The
Geographical Information System (GIS) and Remote Sensing (RS) techniques
have recently been widely applied to study land-use/land cover changes
