UR  - https://www.hausarbeiten.de/document/276342
N2  - Increasing population needs increased amount of food stuff as well for the survival resulting in the conversion of bare and forest land into agricultural lands for maximum productivity. During last few decades the population of Pakistan is increasing tremendously and the lands are being converted into agricultural lands. The major point of concern is the impact of these lands on watershed area which not only contributes water into the Mangla dam but also the sedimentation problems are observed. This study focuses on the impact of agriculture on the study area. 70% of the total population is associated with agriculture for livelihood among which mostly farmers are uneducated. Most of the lands which were covered with forest and wild trees are now converted into agricultural lands and soil erosion problems are increased. Satellite images of different resolutions were obtained from World Wildlife Fund for nature-Lahore and private organization “JERS” Lahore. Population and agricultural data was obtained from census report 1998, questionnaire and interviews from local community. By this data, vegetation cover of 1992 and 2000 was extracted as well as present landuse classification is done using ArcGIS software and it is observed that the vegetation cover is decreased drastically due to deforestation for agriculture during last few decades.
