Assessment Of Ecological Impact And Restoration In The Former Refugee Camps In Kibondo District, Tanzania

ABSTRACT There is growing concern on environmental degradation and human population displacement. This study adopted multiple models that consider the variables linking human population displacement and local environmental degradation. The main concern of this study is tied on refugee ecological impacts as consequence of spatial and temporal changes in land use and land cover. The study adopted a combination of descriptive research design and integration of RS and GIS techniques in ...

Environmental Impact Of The Mobile Telecommunication Technology In Accra, Ghana

ABSTRACTCurrently, there are over 10,000 telecommunication base stations (BSs) in Ghana. Experts insist the number of BSs is practically inadequate to ensure quality service nationwide. However, in Accra and other urban centers the installation of BSs to expand coverage has met opposition from the public. Accra has a population density of over 15,000 persons per km2 with an annual growth rate of 4.4%; hence, the number of people estimated to live closer to BSs is higher in Accra than in any o...

Environmental Impacts Of Active And Decommissioned Landfill Sites In The Accra Metropolis: A Case Study Of The Pantang And Mallam Landfill Sites

ABSTRACT The study investigated the impacts of the Pantang and Mallam landfill sites in the Greater Accra Region on the surrounding environment. The Pantang landfill site is an active site that still receives waste of all kinds from various parts of Accra. The Mallam landfill, on the other hand, was decommissioned over a decade ago. Samples of leachate from the two landfill sites and air in the vicinity of the respective sites were taken over a period of three months and analysed. Soil ...

An Assessment Of Dredging As A Tool For Managing The Effects Of Sandbar Development At The Volta Estuary

ABSTRACT The construction of dams on the Volta River and the consequent regulation of the river‘s flow pattern led to the development of a permanent sandbar at the Volta estuary that resulted in many problems for the estuary, with the major one being the disruption of salt water in-flow. Poor salinity conditions of the estuary resulted in, among other things, the development of freshwater plants which served as breeding grounds for some planorbid snails which harboured the parasites t...

Water Quality of the Kpong Headpond

ABSTRACTThe Kpong Headpond was formed in 1982 when the Lower Volta River was dammed atAkuse. The main uses of the water in the Headpond are for hydroelectric powergeneration, domestic and industrial use and for irrigation. Several activities however, tendto put this body of water at risk of pollution. These include poor waste disposal, poorfarming practices and extensive human and animal contact with the water. An eightmonthfield study was undertaken to monitor the water quality of the Kpong ...

An Assessment of Environmental and Economic Effects of Tourism in Communities Around Wli Waterfalls and Lake Bosomtwi in Ghana

ABSTRACTThe study sought to assess the effects of tourism on the environment and economicactivities in the communities around Lake Bosomtwi and Wli Waterfalls. Methodologyused included analysis of water samples from the Lake and Waterfall. Satellite imagescovering the period between 1990 and 2010 of land use around the Lake Bosomtwi andWli Waterfalls were also analyzed to see if tourism is affecting vegetative cover aroundthe Lake Bosomtwi and Wli Waterfalls. In addition, a social survey and ...

Strategic Environmental Assessment (Sea) As A Sustainability Tool For Policy And Decision Making: A Case Of The Atiwa Forest Management In The Abuakwa South Municipality Of Eastern Region Of

ABSTRACT Environmental degradation and the unsustainable exploitation of non-renewable resources continue to increase to satisfy socio-economic demands which call on a National Development Agenda to make use of Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA) as sustainability tools imperative. The use of these tools is to balance environmental and economic sustainability with institutional capacity building, and social cohesion to direct the sustainab...

In Phase 1, 15 plant species made up of grasses and legumes namely: Paspalum. vaginatum, Cynodon.dactylon, Pueraria. phaseoloides, Centrosema. pubescens, Panicum. maximum, Schrankia. leptocarpa, Eclipta. alba (Linn.), Cyperus. haspen (Linn.), Melastromastrum. capitatum, Acreceras. zizanoides Dandy, Pteridum aquilinum (Linn), Lu...

Evaluation of Agricultural and Agro- industrial Residues for Composting for Agricultural Use in Ghana

ABSTRACT Ghana produces several hundred million tons o f agricultural and agro industrial residues annually. In the Kwaebibirem District in the Eastern Region o f Ghana the processing o f fruits o f the major tree crops such as oil palm and cocoa together with the large cultivation o f rice and maize generate high amounts o f agricultural and agro industrial residues. Oil palm residues comprising empty fruit bunches (EFB), palm oil mill effluent (POME),mesocarp fibre(MF) and palm kernel...

General Circulation and Principal Wave Modes in Andaman Sea from Observations

Objectives: This study intends to describe the Andaman Sea circulation and investigate the dominant modes of variability in the basin. Analysis/Observations: The domain experiences stronger South-westerly winds from May to September and relatively weaker North-easterlies from November to February. A strong negative Ekman pumping along the north coast of Indonesia is observed during Summer. The transport of water across the straits of Andaman and Nicobar Islands (ANI) is computed by simple mas...

Role Of Government And Community In Landslide Risk And Vulnerability Reduction: A Case Study Of Gakenke District, Rwanda

ABSTRACTThe frequency and the severity of landslides have increased in recent times globally, with serious implications for human lives and property, as well as national economies. In many disaster response initiatives, community-based disaster management approach is adopted as a quick solution to emergency response. This study was carried out in Gakenke District in the Northern Province of Rwanda, which is highly prone to landslide disasters. It investigated the role of government and local ...

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...

Toxicological Evaluation of Biodiesel Emission Particles (BEP) Using Rat Models

AbstractThe present study is an attempt to elucidate the effect of biodiesel emission particles (BEP) on some antioxidant  enzymes of selected tissues of rats. Rats were exposed to emission particles (EP) of biodiesel blended with fuel  diesel at 100BD, 75BD, 50BD and 25BD as well as fuel diesel (FD) over a period of ten days. Enzyme assays  were conducted for superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX) and reduced  glutathi...
