Screening Reactive materials for permeable barriers to treat Benzene and Lead Contaminated Groundwater
Laboratory batch experiments were performed to: (i) select two individual and two mixtures of potential reactive materials for permeable barriers to treat groundwater contaminated with benzene and soluble lead (Pb2þ); (ii) investigate the involved contaminant removal mechanisms; and (iii) determine the permeability and assess the environmental compatibility of the selected materials. -

Enhanced electricity generation and organic matter degradation during three-chamber bioelectrochemically assisted anaerobic composting of dewatered sludge
Composting microbial fuel cells can generate electricity from recycled organic waste at accelerated degradation rates. However, the problem of high internal resistance (Rint), which results in low power density, is a technical obstacle related to this process, and the preferential conversion of the organic fraction by bioelectrogenesis remains unclear. -
Street vending and the use of urban public space in Kumasi, Ghana.
In many cities all over the world, urban public space has become the place of work of the urban poor. This paper seeks to examine how street vendors use public space for their livelihood and the response by the Kumasi Metropolitan Assembly to control street vending. -
Influence of the entrepreneur and enterprise characteristics on success of cage fish farming in the Asuogyaman and South Dayi districts, Ghana
Aquaculture is becoming a very important source of income for many people as well as a source of protein in their diets. This study examined the influence of the entrepreneur and enterprise characteristics on small-scale cage fish enterprises in the Asuogyaman and South Dayi Districts. -
Suitability of some Ghanaian mineral Admixtures for Masonry Mortar Formulation
The suitability of masonry mortar for various constructional applications is dependent on some vital engineering properties and production cost. In a majority of masonry formulations, ordinary Portland cement (OPC) is the principal binding agent. -
Land Suitability Assessment and Landuse Planning: A Prerequisite for Food Security and Climate Change Adaptation
Though Ghana’s crop yield growth rate was at 17%, 5% of every 1.2 million Ghanaians have insufficient and limited access to nutritious food. Climate change and climate variability have enormously affected the state of agricultural productivity and hence could result in food insecurity. As many ongoing projects use Boolean suitability analysis, land use planning, management recommendations sores, it still remains inadequate to support rural resource poor farmers. This then, is affecting livelihood and agricultural productivity. In this paper, a geostatistical quantitative method to support a geographic information system (GIS) based on multi-criteria decision support system (GMCDSS) for an enhanced land suitability assessment (LSA) and landuse planning (LP) was devised. -
Under-reporting of Road Traffic Crash Data in Ghana
Having reliable estimates of the shortfalls in road traffic crash data is an important prerequisite for setting more realistic targets for crash/casualty reduction programmes and for a better appreciation of the socio-economic significance of road traffic crashes.
