SPATIO-TEMPORAL DISTRIBUTION OF FOREST IN SOMB RIVER MINI WATERSHED
Journal Title: PARIPEX-Indian Journal of Research - Year 2019, Vol 8, Issue 4
Abstract
Due to anthropogenic activities, the Earth surface is being significantly altered in some manner and man's presence on the Earth and his use of land has a profound effect upon the natural environment thus resulting into an observable pattern in the land use over time. Land Use and Land Cover (LULC) change is a major issue of global environment change. The base map of the study area was prepared using Survey of India Toposheets. Two different time satellite images were used (LISS-III 1998, LISS-III 2010). Unsupervised technique was used to identify the forest in study area. The main objectives of this study are to examine the status of forest in Somb river watershed and to identify areas of major change in time period of 1998-2010. This paper explains about the present status of forest conditions in the study area, which is one of the most striking resources available. The forests in the study area have mainly four types i.e. Siwaliks Chir-pine, Siwaliks Sal, Northern Dry Mixed Deciduous, and Dry Bamboo. Vegetation cover provided by forest, impeded the velocity of runoff on soil surface checks, soil erosion, silting and landslides, thus reducing the drought or flood. Presently, increasing mismanagement as well as stealthily cutting of forest trees is a serious problem in the study area. There is a need to maintain the quality and quantity of trees in the study area. Somb river watershed was found to have experienced rapid changes in Forest Cover particularly in crop land and Forest land. Forest land has decreased by 224.71 Sq. Kms in 1998 to 168.89 Sq. Kms in 2010. Here forest land converted to crop land and Built-up area.
