Based on the results obtained by employment of GIS and RS applications to achieve the specific research objec- tives, it is concluded that the land use practices in the study area have altered significantly in 26 years. The land use shift in the watershed area was evident by the decline in the area of planted trees, wet land and permanent water sources (5%, 10% and 11% respectively) and augmentation of area covered by classes of settlements (37%), agriculture (21%) and barren land (16%). The haphazard expansion of settlement and cultivated land area in the watershed was mainly due to lack of proper management and land use planning since no EIA report is generated prior to land development in the study area. The major impact of this expansion was subjected on planted trees and permanent water sources to deforestation and water depletion respectively. Additionally, all these alterations in the land use patterns adversely affected water quality and accessibility by 2014 which may prove a limiting factor in the future for both urban growth and agriculture practice and may also be responsible for further loss of already shrinking planted trees cover in this area. Hence, proper management of these water resources is required because without proper management, this valuable water resource will soon be lost or will no longer be able to play its required role in agriculture production and socio-economic development of the area. Having said all that, there are several recommendations based upon the conclusion of the present study for the proper management and conservation of the forest, water and soil resources subjected to decline in the wa- tershed.
