This study investigates the effect of aquaculture on Phytoplankton diversity and abundance in Lake Kariba. Water parameters that were monitored included: phosphate, nitrate and silica concentrations. Water samples were analysed from an aquaculture station at Yalelo fish cages located at Kamimbi...

An important dimension of environmental management that has not received much attention is the link between mining effluent pollution and disruption of farmer’s livelihoods. Most studies on mining in Zambia focus on the impact of mining on environment, human health, cultural issues,...

A semi- cylindrical natural convection Solar Tunnel Dryer (STD) was used for experiments to dry partially field- dried maize cobs with a moisture content of about 30 % wet basis to a safe storage moisture content of 12.5 % wet basis. Air temperatures ranging from 15.8 oC to 20.8 oC above ambient...

Pumpkins and Chinese cabbage are widely grown in peri urban areas with different soil types in Zambia using waste water which is potentially contaminated with heavy metals like copper and cobalt. The objectives of this study were to establish the effect of loading rates of heavy metals on sandy...

Water abstraction is achieved by many means, and for many purposes. Abstraction depends on many variables that include the purpose for the abstraction, the location, the type of laws in place regarding the procedure, and the type of resources available for the abstraction process. The overall...

Zambia has been experiencing population increase over the years. The growth has been characterised by an increase in agricultural irrigation activities, competitiveness in water use which have caused water stress and conflicts in some catchments. Some water availability assessment works in...

Heavy metal contamination commonly results from human activities such as mining, and it has become a serious environmental problem. Heavy metals are an important category of the industrial pollutants due to their non-biodegradability. One of the most cost-effective strategies for dealing with...

Management of Non-Revenue Water (NRW) has been undergoing several and continuous transformations over the past two decades. The International Water Association (IWA) as well as other key stakeholders have been trying to find the ‘Best Practices’ in managing non-revenue water so as to help water...

The total surface area of planet earth is about 510 million Km2 and about 71% of this area is water and the remaining 29% is formed by land mass. The proportion of water is much higher, as it is a major component of physiological existence and includes all types of natural water resources;...

The objective of the study was to provide a holistic evaluation of the impacts of deforestation on ecosystem services in Kamfinsa sub-catchment of Kitwe in Zambia. Loss of forest biomass, biodiversity, and soil erosion were key proxy variables for loss of ecosystem services. Geographical...
