Assessment Of Effluent Quality At The University Of Ghana Hospital, Legon

ABSTRACT Hospitals effluent often contain chemical compounds which may have negative impact on the environment and human health if not properly treated. Investigations were conducted to determine the bacteriological and physico-chemical qualities of effluent discharged from University of Ghana hospital into the environment and its effects on agricultural soils and vegetables. Water and soil quality analyses of some physico-chemical and bacteriological variables were carried out on efflu...

Impact of Charcoal Production on Soil Properties And Vegetables in The Central Gonja District of The Northern Region Ghana

ABSTRACT This study assessed the impact of charcoal production on soil properties, vegetation and the perception of charcoal producers on the environmental impacts of their activities in the Central Gonja District of the Northern Region, Ghana. Data acquired suggest significant differences in the proportions (or fractions) of clay and sand in soils sampled within 0-30 cm depth at sites of charcoal production referred to simply (as burnt sites) and sites with no observable indications of ...

Assessment Of The Effects Of Quarrying Activities On Some Selected Communities In The Lower Manya Krobo District

ABSTRACT This study assessed the effects of quarrying activities on some selected communities in the Lower Manya Krobo District. Questionnaires targeting inhabitants around the quarry sites, observations, collection of health records from well patronized hospitals/clinics and dust (PM10) sampling were used as data gathering instruments. The study revealed that some of the men have been employed as quarry workers and a substantial number of women in the area have become food vendors at the qua...

Market Systems of Non-Timber Forest Products (NTFPs) and their Roles in Climate Change Adaptation- A Case Study of the Lawra Distrivt, Ghana

ABSTRACT Local and indigenous communities depend on Non-Timber Forest Products (NTFPs) in a variety of ways. However, the absence of ready markets for these products limits their livelihood support potential and capacity to support environmental and climate change adaptation efforts. This study examined how the five livelihood capitals i.e. Financial, Social, Physical, Natural and Human (including market access, value chain and product quality standards) affect marketing systems for NTF...

Contribution of Modified Taungya System to Forest Cover And Livelihood of Forest-Fringe Communities. A Case Study of Worobong South Forest Reserve in Ghana

ABSTRACT Decline of natural forest cover through deforestation in Ghana has reached a critical stage. Loss of forest poses many problems, mostly to the communities that rely on the forests for their livelihoods. In the last decade several schemes to protect the remaining forest, restore degraded areas and improve people's access to forest resources have been introduced, of which the Modified Taungya System (MTS), an agro-forestry system, is one of them. The objective of this thesis was ...

The Impact of Septic Tank Effluent on Underground Water Quality of Some Communities in The Ga West District, Ghana

ABSTRACT Investigations were conducted to assess the quality of borehole water and wells in relation to distance from septic tanks in residential households in Ga West District, Ghana. The geographical locations of the boreholes, hand dug wells and the nearest septic tanks were determined using global positioning satellite (GPS). Water quality analyses of some physicochemical and bacteriological variables were carried out on water samples collected from boreholes and wells using processe...

The Effect Of Mining Activities On Smallholder Agriculture: The Case Of Male And Female Farmers In The Mpohor Mining Area Of Ghana

ABSTRACT The study employed the sustainable livelihood approach to investigate the effect of mining activities on male and female smallholder farmers in the Mpohor District mining area.

Geospatial Distribution of Air Pollutants Along Selected Traffic Routes Within Port Harcourt Metropolis

ABSTRACT The study investigates the spatial distribution and concentration of air pollutants (mainly from automobile emission) at traffic intersections at selected major routes within Port-Harcourt Metropolis, Rivers State, Nigeria. Five sampling locations (using purposive sampling technique in selecting the sampling locations) were considered which are Rumuokoro, Rumuola, Garrison, UST/Mile 3 and Mile 1, with each having three sampling points placed 2.0m away from the edge of the road ...

Analysis Of Institutional Solid Waste Management Practices: Insights From Two Ghanaian Universities.

ABSTRACTAcademic institutions produce solid wastes which are not disposed off effectively or economically. The result is littering and accumulation of garbage which cause pollution. This study examined solid waste generation and management practices in public and private institutions. To achieve the above objective, waste audit was carried out over a period of three weeks. Waste management practices of the institutions were also examined through the assessment of the institutional arrangement...
