ABSTRACT Floating macrophytes have the capacity to improve wastewater quality by absorbing nutrients thus purifying pre-treated wastewater and have been found to be more appropriate for effluent in developing countries. This is due to their effective and extensive root system and moderate capital investment required in their engagement in wastewater treatment. They are especially appropriate for tropical countries due to the warm climate experienced in these regions which support rapid plant...
ABSTRACT The informal sector is an engine of growth with more than 1.8 billion people globally and one billion workers in developing countries producing a greater portion of GD (25-60%) in developing countries. It provides employment opportunities to majority of the population in both developing and developed countries. However the sector is unregulated and recorded in government statistics. There are high and tragic incidences of occupational related accidents and injuries that go unabated i...
ABSTRACT Climate change coping strategies play a major role in curbing the effects of climatic shocks especially amongst communities living in Arid and Semi-Arid Lands (ASALS. The study revealed that there are various coping mechanisms applied by smallholder farmers in Kaloleni Sub County. These include marrying off daughters in order to get money for food purchase, stealing food from farm, water vending getting women to work outside home against traditions among others. Preferred coping met...
ABSTRACT Intensive agriculture and cut flower farming which are characterized by heavy use of pesticides and fertilizers have been on the increase in developing countries. A number of consequences are associated with heavy use of pesticides; however weak enforcement of laws and regulations suggests that their use will continue. There is a high possibility that Flower Farm Workers (FFW‟s) lack knowledge in handling, storage and use of pesticides in flower farms leading to increased incidenc...
ABSTRACT The Mara River basin is the lifeline to Maasai Mara Game reserve in Kenya and the Serengeti National park in Tanzania. Its major perennial tributaries are Nyangores and Amala both originating from Mau Escarpment. Unprecedented evidence on change of land use for development purposes in the upper catchment has affected the water quantity, quantity and the environmental sanitation in general. In addition, the municipal town of Bomet situated close to Nyangores River lack adequate sanit...
ABSTRACT The aim of this study is to determine the effects of aerobic exercises on bone-specific alkaline phosphatase and pyridinoline among sedentary women at post-menopause. Menopause has been linked to increase bone turnover, which could lead to osteoporosis and consequently, bone fracture. However, exercises are more desirable in management and prevention of osteoporosis. This study was quasi-experimental involving 20 participants’ sedentary women at postmenopause selected using purpos...
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...
