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 sustainable mana...

ABSTRACT Some environmental impacts such as pollution and widespread of biodiversity loss can be related to the activities of an organisation supply chain. Manufacturing companies such as breweries, instead of investing in environmentally friendly technologies which can help in the prevention of waste at the source, generate large amounts of unnecessary emissions and wastes. The Accra Brewery Limited (ABL) uses a lot of raw materials; it is energy-intensive and generates a lot of waste and e...
ABSTRACT This study was undertaken in three phases to identify (phase 1), screen (phase 11) and evaluate (phase 111) plants for their phytoremediation potential. 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), Ludwigia...
ABSTRACT A LabVIEW simulator of thermal-hydraulics has been developed to demonstrate the temperature profile of coolant flow in the reactor core during normal operation. The simulator could equally be used for any transient behaviour of the reactor. Heat generation, transfer and the associated temperature profile in the fuel-channel elements viz: the coolant, cladding and fuel were studied and the corresponding analytical temperature equations in the axial and radial directions for the coola...
ABSTRACT Anopheles gambiae s.s. larval habitats are important determinants of adult distribution and abundance, which also determines the geographical pattern of malaria disease. Information on their habitat characteristics can contribute greatly to better planning of its control strategies through environmental management. To identify the environmental parameters, which influence the distribution of An. gambiae s.s. larval populations in urban Accra, Ghana, 30 habitats with An. gambiae s.I....
ABSTRACT Malaria is a threat to more than 40% of the world's population accounting for more than 300 million acute cases and between 1.1 and 2.7 million deaths annually. Over 90% of the malaria cases are in sub-Saharan Africa, constituting 10% of the total disease burden. Currently, activities support the extensive use of insecticide-treated materials for malaria control. However, these efforts are threatened by the evolution of resistance in the main malaria vectors, Anopheles gambiae s.l. ...
Abstract Cowpea is an important food crop in Africa but suffers from a variety of insect pests. Among those is Megalurothrips sjostedti (Trybom), a major pest that is not successfully controlled by its local natural enemies. One of them, Ceranisus menes (Walker), a cosmopolitan endoparasitoid of thrips larvae provides efficient control of thrips populations in Southeast Asia. This has necessitated a study of this insect which involves a comparison of the biology of the African and Asian popu...
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 cake ...
The economic importance of groundwater in the Greater Accra Region cannot be overemphasized, since supply from boreholes and wells continues to be the most dependable alternative sources of water for most rural and urban communities in the region. Three different consolidated hard rocks underlie the region making it difficult to produce volumes of groundwater for supplies. Demand for portable water has led to the drilling of large numbers of boreholes. This study statistically assesses t...
ABSTRACT The purpose of this study was to evaluate the potential of incorporating tiger nut milk and soy milk in cheese making. In all 16 different formulations were prepared from tiger nut milk, soy milk and cow milk. Texture analysis, colour evaluation and chemical analysis were carried out on all the 16 cheese samples. Two parameters were measured (firmness and fracturability). Protein, fat, moisture content and pH were determined with respect to the chemical analysis. For the colour evalu...
In West Africa, especially Nigeria, Benin Republic, Togo and Ghana, dried yam chips constitute an important food material. The recent introduction of the larger grain borer into Africa and its devastating effect on cassava chips necessitated a study of the biology and damage caused by Prostephanus truncatus (Horn) (Coleoptera: Bostrichidea) and Araecerus fasciculatus (Degeer) (Coleoptera: Anthribidea) on dried yam chips in Ghana. Three yam varieties were investigated in the studies; thes...
The prevalence of counterfeit drugs is seen as a problem faced in both developed and developing countries where Ghana is not an exception. Antibiotics are amongst the most counterfeit drugs in developing countries. What is less understood is that there are inadequate and ineffective quality control procedures in monitoring of drugs manufactured and imported into the country. This research work is aimed at contributing towards the development of routine analytical procedures that will fa...
ABSTRACT The 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...
Abstract Increasing globalization, unprecedented urbanisation, environmental consciousness and technology development has redirected global cities' focus towards strategic and smart solutions to solve issues changing city dynamics through a smart city agenda, African cities included. The smart city agenda has been globally debated via varying perspectives but most of the concept's ideology has been limited to the diffusion of technology; excluding social, human, economic, environmental capit...
