ABSTRACT Changes in river flows for hydro-electric power generation, agricultural purposes and water conservation, and other land use changes have had major ecological, social and economic consequences, which include but are not limited to disasters. The poor who mainly live in rural areas directly depend on most of these ecosystems and the services they provide for their livelihood, and so are more vulnerable to changes in ecosystems. This study was carried out to identify communities in the...
This study was carried out with the aim of assessing the rattle tree (Albizia lebbeck) effects on soil properties and Irish potato (Solanum tuberosum) productivity on the Jos Plateau, Nigeria. In carrying out the research, a randomized complete block design (RCBD) was employed consisting of five treatments and three replicates. The five treatments applied were as follows: Treatment 1 (T1): Irish potato planted in the alley (space) between A. lebbeck tree rows without green manure; T2: P...
ABSTARCT A seismological and geological investigation for earthquake hazard in the Greater Accra Metropolitan Area was undertaken. The research was aimed at employing a mathematical model to estimate the seismic stress for the study area by generating a complete, unified and harmonized earthquake catalogue spanning 1615 to 2012. Seismic events were sourced from Leydecker, G. and P. Amponsah, (1986), Ambraseys and Adams, (1986), Amponsah (2008), Geological Survey Department, Accra, Ghana, Ampo...

ABSTRACT The biodiversity conservation projects that were implemented at Gomoa Okyereko and Gomoa Adam in Gomoa East and Gomoa West Districts in the Central Region were to conserve degraded forests in the two communities. The main problems had to do with using chemicals in hunting of wildlife, regular bush fires, pollution of water bodies, indiscriminate cutting of trees and frequent wind damages. This study therefore assessed the impact of the project intervention in the light of the problem...
ABSTRACT The impact of climate change is now posing a greater threat on the hydrological cycle leading to drought and water stress in small basins. Matters of climate change have now become a primary concern to most nations due to the implication on society and humanity. The study used 17 ensemble climate model from the Coupled Model Intercompersion Project Phase 5 (CMIP5) to estimate the future climatic condition for the 2050s (2035 to 2065) under Representative Concentration Pathways (RCP) ...
ABSTRACT A sufficient, clean drinking water supply is essential to life but millions of people throughout the world do not have access to this basic necessity. Even after the intensive efforts of engineers, planners, builders, governmental and non-governmental organisations (NGOs) to bring potable water to the poorer people of the world, the situation is still a challenge. The problem becomes exacerbated especially in developing countries with an increasing population growth trend. This study...
ABSTRACT Agriculture, which is the main source of livelihood of peri-urban dwellers in Sekondi-Takoradi Metropolis is seriously being threatened by rapid urbanization due to the discovery of oil in the Tano Basin. The oil industry is gradually impacting the urban development pattern of the twin city. Hence peri-urban agriculture has been limited to areas such as riverbanks, roadsides, parks and lands under high-voltage electrical towers that cannot be used for buildings. The main thrust of th...
ABSTRACT Lagoons are highly productive coastal systems that provide natural services to the ecosystem, however, their pollutions cause adverse changes to the natural environment. Korle and Kpeshie Lagoons in Ghana, both receive wastes from industries and municipal sewage. Controlling and monitoring of contaminants in these systems is very important to environmental protection. The study examined the presence of heavy metals (arsenic, cadmium, chromium, copper, lead and zinc) in sediments, cra...
ABSTRACT Improving the microbial quality and safety of cooked food in the school canteen is an effective means of reducing the burden of diarrhoeal diseases among school children. Studies across Africa have highlighted that foods sold on streets pose a great health hazard and contribute significantly to morbidity and even mortality among children. The main objective of this study was to determine the microbiological quality and safety of cooked food sold in canteens in some selected schools t...
ABSTRACT Assessment of viability of an ore deposit depends on the accurate estimation of the quantity and quality of the commodity, which is a function of the sample data quality. SAMEVA Limited, a fully owned Ghanaian company, wants to acquire Kojina Gold deposit as an investment opportunity in the gold industry of Ghana. The decision to invest in the mining industry comes with huge capital requirement and the associated risks are very high. The major objectives with regards to evaluating th...
ABSTRACT The sterile insect technique involves mass rearing of male insects for sterility purpose. This heavily relies on male fitness and genetic compatibility of laboratory-adapted male insects and the wild to ensure successful competition with their male counterpart in the wild. Uniform environment in the laboratory as compared to the wild conditions might lead to genetic drift which might lead to reduced sexual competitiveness, fitness, morphological changes or changes in the sexual behav...
ABSTRACT Cabbage is a well-known vegetable grown in Ghana due to its nutritional value and serves as a source of livelihood for small scale farmers. Its cultivation is constraint by insect pests such as Plutella xylostella (L) (Lepidoptera: Plutellidae), Hellula undalis (Lepidoptera: Crambidae) and Brevicoryne brassicae (Aphididae) which cause significant damage and yield loss. Farmers especially those in the Ketu South municipality of the Volta region apply synthetic insecticides 12-15 times...
ABSTRACT Malaria is a major public health problem in most developing countries. In Ghana, it is hyper-endemic with children under-five years, pregnant women and non-immune visitors being at greatest risk. The National Malaria Control Programme recognizes the use of Insecticide-Treated Nets (ITNs) as one of the multiple prevention tools in the control of the malaria vectors. But due to problems associated with ITNs which include rapid loss of bio-efficacy as a result of repeated washings and l...
ABSTRACT Agriculture is the backbone of most African countries. In Ghana it contributes immensely to the gross domestic product and it employs about 60% of the Country’s labour force, however the agricultural sector in the country is underdeveloped and mainly rain fed. Hence variability of rainfall affects crop production in the country. In spite of the variability of rainfall in the country and as a matter of fact, in the Keta District, farmers have resorted to some coping and adaptive str...
