dc.description.abstract | Assessment of area under agroforestry in Tehri district of North Western Himalaya, Uttarakhand, India has been done using GIS and Remote Sensing technology. The study district is characterized by hilly terrain with varying elevations from 288 m to more than 2800 m. High-resolution satellite imageries (spatial resolution 5.8 m) were used in this study for land uses and land covers classification. According to unsupervised classification, highest area was found under forest class (65.22%) followed by cropland (20.41%). Considerable area was also found under snow cover (9.45%) in the district. Area under agroforestry was estimated to be 5572.26 ha (1.53%) by this method, whereas it was estimated to be 7029.06 ha (1.93%) by supervised classification. Estimated cropland area comes out to be about 20.0 percent. An accuracy of 86.5 percent was found in this classification for agroforestry class. Highest area under agroforestry of 3707.36 ha was obtained in 1200-2000 m elevations followed by 2231.26 ha in 288-1200 m elevations. Negligible area was found on high elevation zones of more than 2800 m. The major agroforestry systems dominated by Grewia oppositifolia, Celtis australis, and Quercus leucotrichophora were identified and mapped and remaining systems were grouped as others class. Estimated area under Grewia oppositifolia, Celtis australis and Quercus leucotrichophora based systems come out to be 2330.82, 1456.80 and 1129.10 ha, respectively. It has been observed from the accuracy assessment that the estimates of area under agroforestry obtained under this study are reliable. | en_US |
