Abstract Decadal changes in land use/land cover for Balachaur watershed in Nawanshahar district, Punjab, India were studied using black and white aerial photographs for March 1984 on approximately 1:20,000 scale and multidate geocoded false colour composites (FCC) of IRS-1D LISS-III on 1:50,000 scale for March 2002, September 2002, and May 2003 and interpreted visually to prepare land use/land...

The Kagera basin is a high value ecosystem in the Lake Victoria watershed because of the hydrological and food services it provides. The basin has faced large scale human induced land use and land cover changes (LUCC), but quantitative data is to date lacking. A combination of ancillary data and satellite imagery were interpreted to construct LUCC dynamics for the last century. This study is an...

Atmospheric deposition of heavy metals and other pollutants has substantially increased due to human activities over the past several hundred years. For some metals such as lead and mercury, these changes have been well studied because of their potentially harmful impact to human and ecosystem health. However, some aspects of metal transport and storage in the environment are still not well und...

Research in pristine forests provides a necessary reference of energy and nutrient cycling in absence of anthropogenic influence. Therefore two unpolluted watersheds in the Cordillera de Piuchué of southern Chile (42 ◦30′ S) were chosen for detailed ecosystem analysis. The goals of this study were to quantify the distribution of the living biomass in the research watershed and to document topog...

the aim of this study was to assess the conversion of forest to vineyard on different physical pools of organic matter in zrebar lake watershed. soil samples were collected from the two major land use types including forest and vineyard land at 0-30; 30-60, and 60-90-cm depths. in each land use, different soc fractions were measured. according to the results of size fractionation of organic car...

Economic valuation of water production service in forest ecosystems (case study: Darabkola watershed)

The Coweeta Hydrologic Laboratory, USFS Southern Research Station, worked with state and local agencies and various organizations to provide guidance and tools to reduce sedimentation and facilitate restoration of the 1900km2 Conasauga River watershed in northern Georgia and southern Tennessee. The Conasauga River has the most diverse aquatic ecosystem of any river in the region and is currentl...

Quantification of the changes of water balance components is significant for water resource assessment and management. This paper employed the Soil and Water Assessment Tool (SWAT) model to estimate the water balance in a mountainous watershed in northwest China at different spatial scales over the past half century. The results showed that both Nash-Sutcliffe efficiency (NSE) and determination...

Moose have recently re-colonized the temperate forests of southern New England, raising questions about this herbivore’s effect on forest dynamics in the region. We quantifi ed Moose foraging selectivity and intensity on tree species in relation to habitat features in central Massachusetts. Acer rubrum (Red Maple) and Tsuga canadensis (Eastern Hemlock) were disproportionately browsed; Pinus str...
