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...

This study explored the effectiveness of the Sustainable Operation and Maintenance Project (SOMAP) model implement in six rural districts of Zambia. This study targeted Chongwe district in Lusaka Province. The key findings of the study showed that the communities did not regularly contribute...

This research assessed the public health risk of bacteriological water contamination of the Kafubu River in Zambia against the backdrop of limited research on the ambient surface water quality of the river that is flowing in a catchment area characterised by high human activity. Human activity,...

An extended quasi-metric q on a nonempty set X without any assumed structure is a distance functional that satis es the usual properties of a quasi-metric except that it can assume values of in nity, in addition to non-negative real values. Given a quasi-metrizable space X we exhibit a universal...

Zambia is largely a mineral economy faced with challenges of designing a tax system that meets two fundamental objectives namely to ensure a fair share of rent for itself and simultaneously allowing for sufficient investment revenues needed by investors. Zambia’s mine fiscal regime has evolved...

Water is finite and essential to sustaining human life. It plays a vital role in many human activities including industrial production, agriculture, energy, sanitation, and transportation, in addition to sustaining ecosystems that provide valuable services to both environment and human. The...

In 2015 unparalleled energy crisis was experienced due to depleted energy stocks in the hydroelectric dams and reduced river flows in the Kafue and Zambezi river basin and the northern water circuit. In the past, energy profile of Zambia showed serious imbalance due to over dependence on one...
