Zambia has been experiencing adverse impacts of climate change. Generation of climate information about changes in future precipitation and temperature is useful in designing adaptive measures. Currently, global climate models (GCMs) are primary tools utilized to simulate the present and future...

The topic of the study is “Dynamics of Extension Studies at The University of Zambia from 1966 to 2014: Its History, Contribution to Human Resources Development and Prospects”. The statement of the problem is that although Extension Studies has been in existence at the University of Zambia (UNZA)...

The University of Zambia introduced blended learning in various programmes under the Graduate School of Business in 2015. These programmes were scheduled to run for 18 months with students choosing to be either on Blended Learning or 100% Online Learning. The programme has however had challenges...

There has been controversy amongst economists regarding the nature of the relationship between trade openness and economic growth. The standard neoclassical model of exogenous growth postulates that changes in trade openness can only affect the pattern of product specialization but not the long...

In Zambia, most crops are mainly produced by small scale resource poor farmers who rely on soils with inherently low fertility. When soil productivity declines farmers put affected fields on fallow to allow the fertility to regenerate, and open up new fields. This type of farming is not...

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...

Past and present-day erosion is a significant form of land degradation that has rendered vast areas of sloping land unproductive with respect to crop production. Thus, conservation tillage, along with complementary practices such as soil cover and crop diversity has become a better option to...

Organic amendments have been known to improve soil physical and chemical properties in sub-Saharan Africa. However, research information on how organic amendments affect aggregate stability and the degree of their effects in comparison to others is indaquate in Zambia. The study was therefore...

In machining operations, the effects of high temperatures are i) reduction in tool life, ii) production of hot chips and iii) inaccuracies in workpiece dimensions. Coolant is applied to convey away heat to extend tool life and ensure a good surface finish of the workpiece. While conventional...

Agricultural practices that conserve soil moisture are inevitable in the face of erratic rains and constant droughts. Mulching can improve water productivity through increase in water retention and reduction in surface evaporation. The study was conducted in Lundazi District of Eastern Province...
