ABSTRACT The oil crops sector had been identified as one of the entry points in the execution of the food reliance and a vehicle for poverty reduction by government of Kenya (MoA, 2008). As a result many studies and development projects aimed at promoting soybean and sunflower in Kenya have been undertaken since the 1990s. While a lot of studies have been based on low adoption of these crops, challenges like gender roles, access to and control of the farmland remain undocumented. To address t...
ABSTRACT The efficiency of the sewage works depends on the quality and quantity of the influent and the design of the sewage works. Inefficiency of the sewage work has adverse health impact to the aquatic ecosystem. Pollutants can bio-accumulate and bio-magnify in the food chain causing health impact to both human being and wildlife. The main objective of this study was to assess the effectiveness of wastewater management system of Njoro industrial sewage works. This study used descriptive re...
ABSTRACT The pressure on the wildlife in Lake Chilwa Biosphere Reserve (LCBR) has been increasing due to increase in population, illegal and unsustainable hunting practices. This has become a threat to sustainability of fish, birds and other wildlife species in LCBR. The broad objective of this study was to assess the status of poaching, its impacts and food security as one of the key drivers in LCBR in Malawi. The study employed a social survey research design. One hundred households were sa...

Sanitation is one of the issues that the world cares about lately because of its negative effects on the environment and society especially when it is discharged into rivers and seas without treatment where it affects the fish, agricultural and animal resources. In addition, waste water from hospitals contains many infectious and dangerous compounds, which must be properly treated and then disposed of within the sewerage network. The study aimed to address the problem of the sewage syst...
ABSTRACT Solid waste management contributes tremendously in upholding public health by reducing the risk of diseases and environmental pollution. Despite the significance of this job, solid waste workers are exposed to a myriad of work related hazards. The objectives of the study were to identify the types of waste which are hazardous to solid waste workers, followed by examining the nature of hazards and to finally assess the effectiveness of the measures in place to combat the occupati...
ABSTRACT Purpose of the research: Research into Enterococci is increasingly important as Enterococci was classified as high priority bacteria regarding antimicrobial resistance. Improvements in medical care have also increased the chances of survival of infants with low birth weight. These infants have an increased chance of infection by antibiotic resistant Enterococcus species due to their low birth weight which is further increased by increased hospital stays. In developing countries neona...
ABSTRACT The presence of toxic heavy metals such as Cr, Pb, Ni, As and Hg in foods constitute serious threat to the health of consumers, particularly humans. Continual consumption of foods with high level of toxic metals can lead to bioconcentration and bioaccumulation with long-term health implications. This study was carried out in Tsumeb, Grootfontein and Otavi local municipal areas in the Oshikoto region of Namibia. The focus was to assess the level, distribution and chemical mobilit...
ABSTRACT Purpose of the research: Malnutrition is a medical condition caused by an unbalanced diet, typically characterised by stunting, wasting and underweight in children. Worldwide, malnutrition causes approximately 45% of all deaths among children under 5 years of age. The largest number of global incidences of malnutrition is observed in developing countries. In Namibia, 24% of children within this age group are stunted while wasting is at 6.2%, (the highest in Southern Africa). The mai...
ABSTRACT Introduction A determination of the phenotypic frequencies of blood group systems C, c, E, e and Kell among the Namibian blood donors and pregnant women and the prevalence of these antigens in Namibia was carried out. Two thousand nine hundred and eight six blood donor specimens and four hundred and eighty-four specimens from pregnant women were randomly selected for antigen characterisation. Donated specimens that were processed for grouping and Transfusion Transmissible Infections ...
ABSTRACT Background: Mycobacterium Tuberculosis commonly referred to as (TB) is still one of the major health concerns, with high prevalence globally as well as in Namibia. While significant progress has been achieved in the prevention and treatment services of TB in the country, including use of community-based service providers and community-based health workers, the number of relapse cases remained high. The study aimed at assessing the role of Community Based Service Providers in the prev...
ABSTRACT BACKGROUND Group B streptococcus (GBS) naturally colonises the lower gastrointestinal and female genitourinary tract. It poses a great risk of morbidity and mortality to infants born to colonised mothers. It is highly implicated in maternal infections such as endometritis and chorioamnionitis as well as neonatal infections such as pneumonia, meningitis and septicaemia. It also causes stillbirths and miscarriages in colonised women. Group B streptococcus infection in neonates is class...
ABSTRACT Vehicle exhaust fumes emission, as one of leading major source among smoke producing air pollutants, was examined in this study. Nairobi, a mega-city with increasingly high levels of air pollution was studied with special emphasis on one of its roads, Waiyaki Highway. Objectives were to find if there is air pollution, air pollution effects growth and stress of plants. This road was investigated to gain scientific understanding of the effects of vehicle fumes on plants. Hotspots (ICEA...
Abstract The study sought to assess the impact of occupational stress on employee performance at Hwange Colliery Company Limited. The study aimed at identifying sources of occupational stress, determining the impact of occupational stress on employee performance, as well as examining the strategies to curb occupational stress on employee performance. The research employed quantitative (Questionnaires) and qualitative (interviews) research methods. The research established that job insecurity...
ABSTRACT Land use changes, rapid population growth, poverty, climate change variability and lack of livelihoods diversification aggravate watershed degradation through inappropriate land use methods resulting to water scarcity, land and water pollution, and governance issues. Soil erosion and siltation has led to land denudation, habitat loss and farm lands losing their soil fertility and compromising food security. The main objective of the study was to find out how land use methods influenc...
