Mine tailings are a significant source of heavy metal contamination for soils in their proximity. In Zambia’s Copperbelt Province, historical and current mining operations have resulted in large outputs of tailings. Food crops grown on contaminated soils may be a conduit for transfer of heavy...

Reservoir sedimentation is one of the temporally and spatially distributed challenges facing managers of small reservoirs today. Fluvial system formed the geomorphological plinth of the study. The study was motivated by the problem of sedimentation in the Makoye Reservoir (about 60500 m2), which...

Numerous plants are considered weeds in agriculture and reduce crop yield and quality. Eliminating the deleterious effects of weeds is the goal of weed management. Herbicides are one of the methods of weed management despite some being persistent in the soil. Herbicides such as Stellar star whose...

Lead (Pb) and Zinc (Zn) were mined in Kabwe from 1904 to 1994, generating large quantities of solid mine waste. Among the solid wastes, were tailings from the leach plant which are now an environmental concern because of their high contents of Pb, Zn and other potentially toxic metals. To prevent...

Biochar is an organic residue combusted under low oxygen conditions, resulting in a porous, low-density carbon-rich material. Biochar has the potential to reduce pollutant mobility when used as an organic soil amendment. Until recently, Biochars’ potential has not been extensively evaluated for...

Access to safe and affordable drinking water is a basic need for every human being. Therefore, the main aim of this study was to assess Lusaka Water and Sewerage Company’s (LWSC) Operations Strategies in its endeavor to provide safe and affordable water services in Lusaka’s uprising residential...

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...

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...

Siavonga district has for the last two decades experienced rainfall that is declining, unpredictable and poorly distributed and increasing temperatures. Climate impact studies on Lake Kariba Kapenta fish stocks show that increased temperature and reduced rainfall are the main climatic factors...

This study was aimed at ensuring Kabwe Municipal Council had a clean environment. As part of contributing to solving the problem, this study analysed the possible measures to tackle the problem of solid waste management. The overall purpose of this study was to evaluate the impact of the...
