ABSTRACT Laboratory and field studies were conducted to investigate the toxicity, antifeedant activity, moulting inhibition property and persistence of two neem seed extracts against the cocoa mirids Distantiella theobroma (Dist.) and Sahlbergella singularis Hagl. The study also investigated the effects of neem extracts on nontarget arthropods. Propoxur (Unden 200 EC) was used for baseline comparison. In the laboratory bioassays, the neem was applied at the concentrations of 5%, 10%, 15%, 20%...
ABSTRACT Mangroves and other blue carbon systems are under high pressure due to population pressure and coastal development. The continuous degradation of mangroves leads to the loss of the carbon stocks stored in the mangrove ecosystem. In this study, GIS based analysis using Landsat images and allometric equations were used to estimate the above-ground carbon stock of mangroves in the Lower Volta area in Ghana. The Landsat images were classified to obtain the mangrove area. An ASTER GDEM co...
ABSTRACT The influence of human behaviour and culture on open defaecation has attracted global concern in recent times. As a way of placing the behavioural and cultural factors influencing open defaecation behaviour in Ghana on the public agenda, a school-basedcross-sectional study was conducted in eight first cycle schools selected from eight communities within the Eastern and Volta regions of the country. The objective of the study was to explore the behavioural and cultural factors inf...
ABSTRACT Human beings are always exposed to background radiation that comes both from natural and man-made sources. Natural radioactivity is widespread in the earth environment and it exists in various geological formations such as earth’s crust, rocks, soils, plants, water and air. Mining has been identified as one of the potential sources of exposure to naturally occurring radioactive materials (NORM). However, mining activities are not being monitored and regulated for NORM in Ghana. Mos...
ABSTRACT Although recent statistics reveal a decline in poverty in Ghana, many people still live below the poverty line. Rural small-holder food crop farmers are the most vulnerable groups affected by poverty. This is due to their limited access to micro-credits. The Adventist Development and Relief Agency (ADRA) is a Non Governmental Organization in Ghana and has been working with small-holder farmers in the Yilo Krobo District with the aim of improving rural income and improving the well-be...
ABSTRACT Renovation, a term most commonly associated with buildings is known to be the act or process of improving the existing condition of a broken, damaged or outdated structure. It is the process of restoring to a good condition or making new again a building structure currently in a bad state. The concept of renovation as it relates to buildings will always remain relevant as long as every newly purchased item have a tendency of wearing out over a long period of usage. Reasons for renova...
ABSTRACT A major constraint to increased and sustainable production of tomatoes is its infestation by insect pests particularly the tomato fruit worm Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae). The control of this insect relies heavily on the use of synthetic insecticides which have negative environmental effects. Some insects have developed resistance to certain insecticides. Efforts are therefore being made to look for alternative control strategies that are environmentally-safe...
ABSTRACT Pesticide use pattern on exportable pineapple (Ananas comosus L. Merr.) (Smooth Cayenne) was studied in the Akwapim South District of Ghana through administration of questionnaires. Among the several pesticides listed as being used, only nine, representing 43%, had been provisionally approved for use on exportable pineapples. Farmers handled pesticides carelessly without necessary caution though they had general awareness of hazards of pesticides. Residue levels of chlorpyrifos...
ABSTRACT Wetlands are vital ecosystems with important social, economic and environmental functions. The Ada Songor lagoon (located in the Dangbe East district, Greater Accra Region), is an internationally designated wetland (Ramsar site). Intense anthropogenic activities have impacted negatively on the quality of water and sediment in the lagoon. The study assessed the extent of heavy metal, pesticide residues and nutrients contamination of surface water and sediment in the Ada Songor Lagoon....
ABSTRACT Indigenous knowledge (IK) plays an essential role in reducing degradation and support structures for improving livelihood in freshwater resources. It is asserted that local knowledge helps to build stable governance structures and policies to control abuse and misuse of freshwater resources. The study, therefore, sought to examine institutions and institutional arrangements that govern Lake Bosomtwe. In-depth interviews, focus group discussions and questionnaires were used to solici...
ABSTRACT The increasing cost of healthcare delivery has become a major issue in developed and developing countries. Resultantly, health policy makers are faced with competing alternatives for the systems of healthcare financing. Health Insurance schemes are thus seen as viable alternatives to providing a more sustainable and equitable health delivery system in countries. This study examined the role of the National Health Insurance Scheme in effective child health care delivery in the Ga...
ABSTRACT This study examined the effects of the Bui resettlement scheme on the livelihood of the resettled, host and adjoining households. The study used descrptive study design and employed the mixed method. Cluster sampling was used to select the study communities. The sample size was 283 respondents. Data was collected using interview guide, observation guide, focus group discussion guide and interview schedule. The analyses of data involved the application of descriptive statistics, pair...
ABSTRACT The terrain, morphology, socio-economic characteristics coupled with lateral urban growth and increasing population concentration expose Lagos state to different types of disaster. Studies on disasters in Lagos have focused on the types and their impact to the neglect of vulnerability factors and disaster patterns. This study, therefore, investigated the relationship between urban dynamics (change in population, morphology and urban spatial expansion) and vulnerability to disasters ...
ABSTRACT An effective transportation system is significantly important in sustaining economic growth in modern-day economies as it provides connections between different parts of the country and the global world. Good road network links to work, deliver products to market, underpins logistics and supply chain, and also support local and international trade. However, it has been observed that road traffic congestion has been a major transport challenge faced by cities in Ghana. It is against...
ABSTRACT Cities and traffic have developed hand-in-hand since the earliest large human settlements. The level of urbanisation in the developing world indicates that more people live in cities than before. This blueprint has led to high unbearable levels of traffic congestion in cities, vehicle terminals, streets and thoroughfares. The main objective of the study was to examine issues and challenges with respect to the siting of vehicle terminals in the Cape Coast metropolis. The study employ...
