The grasscutter (thryonomys swinderiamus) is a popular bush meat species in Ghana. It is hunted for its meat and may also serve as a source of income, but there have been concerns recently about some of the methods used in hunting it.
This research was carried out to assess the level of pollution with emphasis on heavy metals contamination and their distribution in the Sakumo wetland, which is being polluted by industrial, domestic and urban runoff. Samples of water, sediment and fish were analysed for the concentration of heavy metals (Arsenic, cadmium, chromium, copper, iron, mercury, nickel and zinc) using atomic absorption spectrophotometry and instrumental neutron activation analysis.
Land degradation is the “the temporary or permanent lowering of the productive capacity of land as a result of human activities. In sub-Saharan Africa, land degradation is especially widespread affecting 20-50% of land and some 200 million people. Land degradation threatens global food security and environmental quality.
The Northern Region is characterised with semi-arid climate. Due to insufficient and polluted surface water resources, groundwater is increasingly gaining significance as the main solution to the water supply problems in the region, especially in the rural areas such as the Savelugu/Nanton district.
This study investigated the environmental and socio-economic impacts of small scale sand winning and quarrying in the Ga West municipality, Greater Accra Region. In all, five (5) water and fourteen (14) soil samples were taken from sand winning and quarrying sites for laboratory analysis. One hundred and fifty (150) questionnaires were also administered at the sites and in the surrounding communities. For the soil samples, pH varied from 4.5 – 6.5 (mean 5.8) at sites with active sand winning activities.
Noise levels in Nungua areas were measured and the effects of noise pollution on memory and hearing were studied. Noise levels were measured in twenty selected schools from Nungua area and it was discovered that, all the schools are exposed to very high level of noise. All the schools studied produced noise levels above 55 dBA, the Environmental Protection Agency recommended Noise Level Standards and Guidelines in educational facilities. A maximum noise level (Lmax) value of 95.8 dBA and a minimum noise level (Lmin) value 51.6 dBA were recorded.
Field experiments were conducted in the Adansi South District of Ghana (604’N 1024’W) with an aim of studying the influence of Allanblackia parviflora trees on vegetative growth and yield of cassava, cocoyam, pepper, okro and maize in agroforestry systems as well as on species of flora in natural agroforestry stands.

Municipal solid waste collection, transportation, treatment and disposal have been a major challenge faced by authorities involved in waste management. The concern here is how to sustainably manage the waste generated, as the population increases. The plastic waste in the Municipal waste stream is increasing, since, it is the most preferred, affordable, very easy to carry, durable and less expensive as compared to glass and metals in the daily household use.
The soil, sediment and water samples in both the inland and the port of the Tema Metropolitan Area were analyzed to ascertain toxic element pollution levels due to anthropogenic activities.In all, thirty five soil samples were taken in the inland surface; 16 sediment samples from the Tema Port; and a total of 20 water samples were taken at both the inland surface and the Tema Port.
