ABSTRACT All life forms including human need water resources in order to live healthy, promote sustainable development and ensure their well- being. The study assessed public willingness to accept and reuse treated wastewater as an alternative water resource to support the dwindling existing water resources for irrigation and the consumption wastewater irrigated crops. A social survey based on random sampling of 232 respondents in Ashaiman, capital of Ashaiman Municipality which has a well di...
ABSTRACT Land use/cover alteration within lake basins is occurring at accelerated rate most importantly in developing countries like Ghana. Anthropogenic activities (livelihood change, population growth, agricultural intensification and practices) and natural factors like seasonal variations are in most situations the major cause. To examine the effects of land use/cover on the physico-chemical and biological properties of Lake Bosomtwi, satellite images of the Lake’s watershed covering the...
ABSTRACT The population within Bongo and Kassena Nankana West Districts, in the Upper East Region of Ghana is estimated to be about 84,545 and 70,667, respectively. An estimate of about 80% of the population depends on groundwater for domestic and agricultural purposes. However, groundwater resources in the Districts is at risk due to anthropogenic activities such as rapid increase in irrigation activities and animals rearing, open defecation and uncontrolled disposal of animal droppings, imp...
ABSTRACT Water is used in almost all human activities and large amounts of wastewater are produced every time. Wastewater need to be treated before it is discharged into the environment because it contains possible harmful substances which can pollute the environment and threaten life. Waste water treatment methods vary from industry to industry according to the process utilized. In most cases, the contaminants are not fully removed from waste water before discharge, due to certain malfunctio...
ABSTRACT This study examines the current state of the shielding integrity of the 38.7 TBq Co-60 gamma ray scanner with an average energy of 1.25 MeV operated by NICK TC Scan Limited, which has been in use for destination inspection at Aflao Border of Ghana, for the past six years, (2010-2016). The facility uses a high energy ionizing radiation in its operation; therefore continuous adequacy of the installed biological shielding is critical to the protection and safety of the workers and the g...
ABSTRACT Although wastewater treatment plants efficiently reduce the loads of pathogens in wastewater, the conventional treatment processes do not show significant removal of antibiotics, antibiotic resistant bacteria and antibiotic resistant genes, resulting in the introduction of these contaminants into the environment. This has human health implications for wastewater reuse and the use of effluent receiving water bodies as irrigation sources. Humans may be exposed to resistant bacteria a...
ABSTRACT Inadequate attention to urban land-use planning and practices could result in the proliferation of unauthorised structures which could destroy the health, beauty and convenience of cities. This thesis sought to investigate the causes and consequences of unauthorised structures at Aboabo, a suburb of Kumasi Metropolis. A total of 244 respondents comprising 119 house-owners, 119 household heads, and 6 key informants (the chief of Aboabo and five heads of Land Planning and Management In...
ABSTRACT A study was conducted to develop a quick and efficient laboratory mass-rearing method for the cocoa aphid Toxoptera aurantii (Boy) and to screen cocoa genotypes for their resistance to the aphid. In a similar experiment, two cocoa genotypes were screened to determine their level of attractiveness to the cocoa capsid Sahlbergella singularis Hagl and the results compared with those from the aphid study. The study formed part of an on-going programme being conducted by the Cocoa Researc...
ABSTRACT In Sub-Saharan Africa, rapid urban growth has outstripped the capacities of central and local government to control and regulate urban land development; hence people construct their homes on available lands most of which are liable to floods. This research set out to identify the driving forces of spatial growth and to simulate spatial growth patterns of structures in the Shama district of the Western Region of Ghana using an agent-based modeling approach. The study was conducted wit...
ABSTRACT Studies were conducted on some aspects of the biology of Chilo aleniellus (Strand) and Sesamia nonagrioid.es botanephaga Tams and Bowden in Southern Ghana. The life cycle of S. n. botanephaga revealed 8 developmental stages; the egg, 5 larval instars, a prepupa and a pupa. Female S. n. botanephaga was found to lay 330 ± 17.7 eggs within a period of 5 days. She required three surfaces to lay her eggs, which were mainly deposited, on the inner side of the leaf sheath fitting tightly...
ABSTRACT With the increasing number of the aged in Ghana, social support for this segment of the population is gradually becoming an issue of great concern. There is debt of research on this. This study is therefore an attempt to provide some information for policy makers towards enhancing planning of better health, social financial support services for the aged to promote their well-being. The descriptive and explanatory survey designs were employed to achieve the objective of the research....
ABSTRACT Thrips are crop pests causing damage to a wide range of crops ranging from fruits to vegetables to ornamentals through direct feeding or oviposition on plants. The main objective of this study was to determine the species composition of thrips and their host range in some selected parts of Greater Accra and Eastern Regions of Ghana. Thrips were collected from flowers, leaves and twigs of vegetable, ornamental and tree crops by beating and jarring and identified to species level. Fi...
ABSTRACT The efficacy of Waste Brewers‟ Yeast (WBY) + Imidacloprid (Akape® ) (insecticide) as food bait was compared with the novel fruit fly food bait, commercially available as SUCCESS APPAT® (GF-120) in the field as attractants for the management of fruit flies in mango orchards at the Coastal Savanna ecological zone for two major seasons (2010/2011 and 2011/2012). Randomised Complete Block Des...
Abstract A year-long investigation has been carried out on atmospheric particulate matter (APM). Elemental composition,mass concentration, sources contributions and their fingerprints were determined in APM samples collected, in Agbogbloshie scrap market, between May 2010 and April 2011. PM2.5 and PM102.5 size fractions of APM were collected 24-hourly on 47 mm diameter nuclepore filters of pore sizes 0.4 µm and 8 µm respectively, using the Gent sampler. Gravimetric analyses were carried out...
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. tow...
