Overgrazing has adverse impacts. It damages the ecosystem and fuels climate change by causing soil erosion, degrading water resources (such as rivers, streams, and the water table), and destroying biodiversity. [29] Ghana's problems with desertification have also been compounded by unsustainable agricultural practices. [30]
The water supply and sanitation sector in Ghana is a sector that is in charge of the supply of healthy water and also improves the sanitation of water bodies in the country. In Ghana, the drinking water supply and sanitation sectors face a number of issues, including relatively limited sanitation access, intermittent supply , significant water ...
Sand and water on the side of the road, causing erosion on the environment Plastic bags dumped by the road side in Katete in mbarara district in western Uganda. The erosion caused by rains, rivers and winds as well as over-use of soils for agriculture and low use of manures have resulted in turning the soils infertile, as for example, in the plains of the Nile and the Orange River.
The Environmental Protection Agency-Ghana and the United Nation Environment Programme initiated an afforestation project of planting trees in the wetland area, using treated waste water as a way of reforesting and conserving the degraded areas. Others are Sakumo Ramsar Conservation and Resource Users Association and the Friends of Ramsar Sites.
The effects stem from the altered hydrological conditions caused by the installation and operation of the irrigation scheme. Amongst some of these problems is the depletion of underground aquifers through overdrafting. Soil can be over-irrigated due to poor distribution uniformity or management wastes water, chemicals, and may lead to water ...
Soil erosion (especially from agricultural activity) is considered to be the leading global cause of diffuse water pollution, due to the effects of the excess sediments flowing into the world's waterways. The sediments themselves act as pollutants, as well as being carriers for other pollutants, such as attached pesticide molecules or heavy metals.
Additionally, Ghana will likely see more cases of malaria and cholera since changes in water conditions impact both. Stagnant water bodies which are formed as a result of some flooding occurrences, may support the breeding of more mosquitoes which will eventually cause the increase in the spread of malaria. [5]
A Köppen climate classification map of Ghana. Ghana's topography. Ghana is characterized in general by low physical relief. The Precambrian rock system that underlies most of the nation has been worn down by erosion almost to a plain. [1] The highest elevation in Ghana, Mount Afadja in the Akwapim-Togo Ranges, rises 880 metres (2,890 ft) above ...
