ASSESSING THE IMPACT OF AN OPERATING TAILINGS STORAGE FACILITY ON CATCHMENT SURFACE AND GROUNDWATER QUALITY: A CASE STUDY OF ADAMUS RESOURCES LIMITED (NZEMA GOLD MINE) IN THE ELLEMBELE DISTRI

ABSTRACT The study assessed the impact of an operating Tailings Storage Facility (TSF) of Adamus Resources Limited (Nzema Gold Mine) in the Ellembele District, Western Ghana, on catchment surface and groundwater quality. Water samples were collected between June and December 2014 from seventeen (17) sampling sites including the TSF decant water (TSF-DW), three (3) streams, a water storage dam, a pond and eleven (11) groundwater monitoring boreholes within 500m radius of the mine’s Tailings ...

EVALUATION OF LOCAL FEEDSTOCKS FOR BIOCHAR PRODUCTION AND POTENTIAL USE OF IT AS SOIL AMENDMENT FOR LETTUCE (Lactuca sativa.L) PRODUCTION

ABSTRACT Agricultural waste can be processed under pyrolysis to generate energy for cooking, resulting in a byproduct called biochar. Biochar has the potential to be used as a soil amendment but this facility has not been explored by researchers. Unpelletized corn cob and oil palm press were subjected to water boiling test, burning duration test, biomass consumption rate, biochar yield, pH of residual water and flame characteristics using Lucia stove. The results generally indicated that corn...

LAND-USE/LAND COVER CHANGE AND ITS RELATIONSHIP TO CHANGING CLIMATE AND CROP PRODUCTION IN THE LOWER VOLTA BASIN, GHANA

ABSTRACT The construction of the Akosombo and Kpong dams have led to a change in the watershed ecology which has in turn contributed to the change in land use and land cover of the Lower Volta Basin (LVB). Inevitable changing global climate has also played a role in the alteration of land cover and crop production which have affected livelihoods. In this study, a post-classification comparison change detection algorithm was used to determine changes in land use and land cover that have taken ...

TOWARDS AN ECOSYSTEM-BASED DISASTER RISK REDUCTION (Eco-DRR) FOR FLOODS IN SOME DOWNSTREAM COMMUNITIES OF THE LOWER VOLTA, GHANA

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...

RATTLE TREE (ALBIZIA LEBBECK) EFFECTS ON SOIL PROPERTIES AND PRODUCTIVITY OF IRISH POTATO (SOLANUM TUBEROSUM) ON THE JOS PLATEAU, NIGERIA

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...

SEISMOLOGICAL AND GEOLOGICAL INVESTIGATION FOR EARTHQUAKE HAZARD IN THE GREATER ACCRA METROPOLITAN AREA

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...

ASSESSMENT OF GLOBAL ENVIRONMENT FACILITY BIODIVERSITY PROJECTS AT GOMOA OKYEREKO AND GOMOA ADAM IN THE CENTRAL REGION OF GHANA

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...

CLIMATE CHANGE IMPACTS ON THE HYDROLOGICAL PROCESSES OF DENSU RIVER BASIN (DRB) USING THE SWAT MODEL

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) ...

RAINWATER HARVESTING IN URBAN GHANA: A CASE OF ADENTAN MUNICIPALITY

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...

EFFECTS OF PERI-URBAN AGRICULTURE ON URBAN POVERTY REDUCTION IN THE SEKONDI TAKORADI METROPOLIS

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...

ASSESSMENT OF PHYSICOCHEMICAL PARAMETERS AND HEAVY METALS CONTAMINATION IN KORLE AND KPESHIE LAGOONS

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...

MICROBIAL QUALITY AND SAFETY OF COOKED FOOD SOLD IN SELECTED SCHOOL CANTEENS IN THE AKUAPEM NORTH MUNICIPALITY

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...

ESTABLISHING THE KOJINA GOLD DEPOSIT AS A VIABLE MINING VENTURE FOR SAMEVA LTD, GHANA

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...

COMPARATIVE BIOLOGY AND REPRODUCTIVE BEHAVIOUR OF A LABORATORYADAPTED REDCO STRAIN OF ANOPHELES GAMBIAE GILES (DIPTERA; CULICIDAE) AND WILD POPULATIONS OF THE SAME SPECIES.

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...
