Application of Remote Sensing and GIS in Monitoring Land Use and Land Cover Change in the Nandoni Dam Basin
Land use activities and land cover (LULC) changes have been widely acknowledged as the main drivers of environmental change at all spatial-temporal scales in some South African dam basins. The consequence of these land use activities causes encroachments, land cover changes, sediment deposits, …

Assessing the impacts of riparian land use on gully development and sediment load : a case study of Nzhelele River Valley, Limpopo Province, South Africa
Human activities on land degradation have triggered several environmental problems especially in rural areas that are under developed. The main aim of this study is to analyse the contribution of different land uses to gully development and sediment load on the Nzhelele River Valley in the Limpopo …

A study of land use conflicts in Mapungubwe area
This study uses lens to understand conflict over the use of land and its resources in the Mapungubwe area. The main underlying assumption of the study is that various land use activities that are not compatible with each other lead to land use conflict. The aim of the study is to assess land use …

Levels of Heavy Metals in Sediment Samples from Select Creeks in Metro Vancouver, BC, Canada
… BC, Canada were analyzed to assess how different land use activities affect physicochemical properties in surface water and metal concentrations in sediments. The pH, total dissolved solids and electrical conductivity in surface water samples ranged from 5.50 to 8.27, 14.0 to 410.0 ppm, and 19.0 …

The relationship between land-use and urban freeway interchanges
… accepted that there is a relationship between land-use and transportation. Transportation facilities influence the location and intensity of land-use activities while these activities generate the need for transportation. The thesis assumes that in general such a relationship exists and, in …

Planning Gone Hog Wild: Mega-Hog Farm in a Mountain West County
… some rural communities have attempted to attract land use activities that are normally seen as undesirable. One example of these undesirable industries is the hog concentrated animal feeding operation, or CAFO. While a number of studies have explored the socio-economic and environmental aspects of …

Macroinvertebrate Biomonitoring Criteria and Community Composition in Seasonal Floodplain Wetlands of the Upper Missouri River
Regulated river flows and land-use activities have altered the floodplain ecosystem within the Upper Missouri River basin. These changes have led to decreased connectivity between the floodplain and main river and enhanced land-use activities (i.e., agriculture) within the floodplain. Knowledge of …

Algal Biomass Accrual in Relation to Nutrient Availability along a Longitudinal Gradient in the Upper Green River, Kentucky
… Abiotic factors include underlying bedrock and land-use activities (e.g. agriculture, septic systems). Nutrient availability directly affects growth, productivity, and community structure of primary producers. The purpose of this study was two-fold: (1) to assess the relationship between ambient …
