The rapid population growth of Lusaka has brought adverse effects on water supply and sewage treatment facilities in the District. Consequently, authorities in Lusaka have allowed use of septic tanks and boreholes in the same area in some Townships. St. Bonaventure located about 7km from Town...

The Nchanga and Konkola ores have substantial amounts of cobalt in the form of Carrollite (CUC02S4) and Cobaltiferous pyrite ((Co,Fe),S2). These minerals are found in association with copper minerals such as chalcopyrite (CuFeSz), Bomite (CusFeS4) and Chalcocite (CujS). However, the recoveries of...

A study was conducted to determine the net carbon sequestration potential of citrus to mitigate climate change. Perennial crops such as citrus have the potential to absorb and sequester carbon dioxide from the atmosphere, save for the carbon released back through the application of agro-chemical...

Environmental problems at the global, regional and local levels have been escalating at such a rapid rate in the last few decades that they have emerged as a major concern for the international community, particularly the educational planners and curriculum developers. The underlying objective of...

The before-and-after study design (also known as the pre and post-test design) was carried out with objectives of (i) determining the potential reduction in greenhouse gas emissions associated with changing pig manure management systems from the use of slurry pits (baseline emissions) to...

Evapotranspiration (ET) is a dominant hydrologic flux in the water budget of semi-arid areas.Thus, accurate estimation of its dynamics in such environments is critical for improvingN water resources management. In this study the physically-based Surface Energy Balance System (SEBS) model was...

The objective of this research was to characterise the rockmass to determine appropriate support system for the decline with the 4.5m height and 4m wide in highly aquifer strata, recharging the water flow of 18, 000 cubic meters per day. As a result production targets reduced due to excessive...
