PROFILE OF MAJOR RIVERS IN GHANA Ghana is drained by the Volta, SouthWestern and Coastal Rivers Systems covering 70%, 22% and 8% respectively of the total area of the country. The Volta River System comprises the White, Black and Red Volta and Oti Rivers. The SouthWestern Rivers System comprises the Bia, Tano, Ankobra and Pra Rivers.
Introduction catchment degradation and other distur The Okyeman traditional area encompasses bances on water resources as nutrient three major river basins namely the Densu enrichment of surface water from urban basin, the Birim basin and the Ayensu basin.

The construction of new mines is certain to have an impact on councils across the region. Employment will be created not only at mine sites, but also in support industries such as housing construction, transport, and shopping and personal services. First round impacts will be direct employment in mining,
The effects of smallscale gold mining activities on heavy metal levels in groundwater were determined for the Lower Pra Basin of Ghana. Sixty five boreholes in 45 communities were analysed between...
3 · The Water Research Institute of the Council for Scientific and Industrial Research (CSIRWRI) says it would embark on a climate resilience management of the Pra and Densu River basins. The project titled, 'Building Climate Resilience into Basin Water .
Contamination from mining affects population centers, which are concentrated to the west of the Andes, as well as fragile ecosystems to the west. Active mines, closed or abandoned mines, informal mining, natural leaching, agriculture and other industries often affect water quality in the same basin.
Mining in the Congo Basin. However, oil and mineral activity also may discourage deforestation by making agricultural export less profitable and by pulling rural populations into cities and away from forested areas, as witnessed in Gabon and Republic of Congo. In an oil concession in Gabon, forests are well protected and hunting is not permitted.
The Densu Basin is also intensively used for the culti vation of both cash and food crops. Principal food crops cultivated within the basin are , , yam, plan tain, banana, and cocoyam. Cash crops include cocoa, oil palm, papaya, pineapple, mangoes, and citrus.
The basin contains the highest density of settlements (both rural and urban) in Ghana. It has a high concentration of mining activities mainly concerned with gold and other minerals. These large scale mining companies in the basin include AngloGold Ashanti, Perseus Mining Ltd, Newmont Ghana Gold Ltd etc. (Water Resources Commission, 2011).
Agriculture, rapid urbanization and geochemical processes have direct or indirect effects on the chemical composition of groundwater and aquifer geochemistry. Hydrochemical investigations which are significant for assessment of water quality have been carried out to study the source of dissolve ions in the groundwater in some rural communities in the northern part of the Densu River basin.
in environmental conditions. The Densu Basin is the most environmentally stressed basin in the country. Land use activities within the basin are varied and impact negatively on the vegetation cover as well as the river body. These include deforestation activities in the upper parts and extensive farming practices in middle parts of the basin.
negative impacts, on a basin scale. This study looks at the impacts of climate change on water resources, food security and the environment and consequently the socioeconomic situation of the people with the view to develop adaptation strategies to reduce its vulnerability or alleviate the negative impacts on people and the environment.
Despite the large body of literature that has been devoted to heavy metal pollution in Ghana, the results are mixed and are disparate making it quite difficult to elicit a coherent account on the scope and levels of heavy metal pollution in the environment and in biota, especially in humans, across Ghana.
Jun 17, 2019· Uranium Mining in Virginia: A Risky Experiment. Virginia Uranium Inc. is pushing to lift a 30year ban on uranium mining in Virginia so it can mine and mill the radioactive metal, beginning in the Roanoke River basin where the waste would remain toxic for generations.
The findings further indicate that a number of uncoordinated catchment management strategies such as restrictions on farming areas, bans on illegal mining and logging, and others strategies have been instituted in the upper Densu basin to prevent degradation of the river.
anthropogenic activities within the Densu River Basin has necessitated this study using a combination of GIS and DRATIC methods. The study reveal that about 47% of the basin is exposed to high ...
