In this study, remote sensing and geographical information system (GIS) was used to assess spatial changes in the land use/cover (LULC)changes of lower Tesua subwatershed by using Landsat7 ETM+ data between 2000 and 2009. The LULC change detection analysis for year 2000 and year 2009 indicates that Agricultural land with crop and Agricultural land without crop have been increased 18.78 km2 (13.22%) and 0.55 km2 (0.38%). The settlement area has been also increased 5.38 km2 (3.78%). But the Scrub land, Waste land, Water bodies and Standing trees have been found decreased 2.06 km2 (1.45%), 11.56 km2 (8.18%), 4.56 km2 (2.66%) and 6.66 km2 (4.32%) respectively. This study concluded that illegal logging, grazing, population increase and encroachment causes LULC changes in the subwatershed.
