“…According to Rao and Pant (2001), who studied a small watershed in the mid-elevation zone of the central Himalayas, (India) between 1986 and 1996, the annual deforestation rate was 0.57%. During this period, intensification of cultivated land and conversion of natural forests and grazing lands to agriculture, as well as a constant thinning of available forest, was recorded.…”

The green revolution represents one of the greatest environmental changes in India over the last century. The Upper Ganges (UG) basin is experiencing rapid rates of change of land cover and irrigation practices. In this study, we investigated the historical rate of change and created future scenario projections by means of 30 m-resolution multitemporal Landsat 5 Thematic Mapper and Landsat 7 Enhanced Thematic Mapper Plus data of the UG basin. Post-classification change analysis methods were applied to Landsat images in order to detect and quantify land-cover changes in the UG basin. Subsequently, Markov chain analysis was applied to project future scenarios of land-cover change. Fifteen different scenarios were generated based on historic land-cover change. These scenarios diverged in terms of future projections, highlighting the dynamic nature of the changes. This study has shown that between the years 1984 and 2010 the main land-cover change trends are conversion from shrubs to forest (+4.7%), urbanization (+5.8%), agricultural expansion (+1.3%), and loss of barren land (-9.5%). The land-cover change patterns in the UG basin were mapped and quantified, showing the capability of Landsat data in providing accurate land-cover maps. These results, in combination with those derived from the Markov model, provide the necessary evidence base to support regional land-use planning and develop future-proof water resource management strategies.

“…Particularly, deforestation and the subsequent conversion of the land into different land uses such as cropland and grazing areas caused significant changes to soil properties in many parts of the tropical regions (Islam and Weil, 2000;Rao and Pant, 2001;Adolfo-Campos et al, 2007). The amount, rate and intensity of land use changes are mainly considerable in developing countries (Rao and Pant, 2001).The outcomes of these changes are deterioration of soil physicochemical properties, increased soil erosion or soil compaction (Rao and Pant, 2001) and land degradation (Woldeamlak Bewket and Stroosnijder, 2003;Khresat et al, 2008).…”

Assessing the impacts of different land uses on soil physicochemical properties is a fundamental step towards sustainable land management. This study was conducted in Agedit watershed, northwest Ethiopia with the objective of determining the effects of land use and soil depth on soil physicochemical properties. Three major land use types: natural forest, grazing and cultivated lands were selected while soil samples were collected in the 0-20 and 20-40cm depths. Standard soil analytical procedures were followed in carrying out soil analysis. Statistical analysis revealed notable variations due to differences in land use type and soil depth. Sand and clay particles, bulk density, total porosity, pH, organic matter, total nitrogen, available phosphorus, cation exchange capacity and exchangeable K and Na were significantly affected (p ≤ 0.05 and/or p ≤ 0.01) by land use. In contrast, silt, particle density, carbon to nitrogen ratios, exchangeable Ca, and Mg and PBS were not significantly (p > 0.05) affected. With soil depth, higher mean values of total nitrogen, organic matter, exchangeable K and pH were recorded in the 0-20 cm than in the 20-40 cm depth. A shift from forest to other land use types caused a significant decline on soil fertility parameters which contributed to low agricultural productivity. The study area, therefore, needs immediate intervention to protect the remnant forests and to replenish the degraded soil properties for sustainable agricultural productivity.

“…Forests provide several ecologically, economically and socially perspective functions to life viz., water supplies, soil conservation, nutrient cycling, species and genetic diversity and green house gases regulation (Rao and Pand, 2001). Increasing anthropogenic pressure such as land use/land cover changes, air, water, and soil pollution (Fearnside, 2001;Sherbinin et al, 2007), degradation of soil quality and losses in biological diversity causes the threatening of the overall productivity of ecosystem functioning at regional as well as global scales (Noss, 2001; Kilic et al, 2004;Kumar, 2011).…”
