Haematological, blood glucose and insulin profile in sprague-dawley rats experimentally infected with trichinella Zimbabwensis and plasmodium berghei anka.
Malaria and helminth co-infection have been widely reported by other researchers. Despite the increasing knowledge on co-infection, the impact of helminths and malaria on humans and laboratory animal models remains uncertain. ...
Vachellia sieberiana var. woodii a high-altitude encroacher: the effect of fire, frost, simulated grazing and altitude.
ABSTRACT There is increasing evidence that savannas and grasslands throughout the world are experiencing bush encroachment. The replacement of grassy biomes with woody biomes has serious consequences for net primary ...
Assessment of the performance of small-scale water infrastructure (SWI) for multiple uses in Nebo Plateau, Sekhukhune District, South Africa.
South Africa is ranked the 30th driest country in the world and water is regarded as a scarce resource in the country. Limited availability of good quality water has resulted in urban areas receiving more water at the ...
Assessing the performance of smallholder irrigation in South Africa and opportunities for deriving best management practices.
South Africa is a water scarce country. With the increasing demand of water from other users, irrigation, as the largest water user, has to find ways to produce more per drop and meet the food demands of the growing ...
Process and modelling studies in forest hydrology.
The demand for timber products in South Africa, and consequently afforestation, is increasing. There exists, however, abundant experimental evidence that trees utilise more soil water than other dryland crops. Because ...
Crop water requirements for irrigation planning in South Africa.
Irrigation in 1980 accounted for approximately 52 per cent of the water consumed in Southern Africa. The need for planning water resources in the agricultural sector is therefore apparent. Much of Southern Africa's ...
The hydrological effects of fire in South African catchments.
Stream-flow and storm-flow in four small catchments were analysed by the paired catchment method for a response to fire. Two of the catchments were vegetated with over-mature fynbos (the indigenous scrub vegetation of ...
Characterization of flour and starch from Zambian cassava cultivars and application in frozen wheat bread dough.
Abstract available in pdf.
Flood disaster preparedness and impacts on rural households: a comparative study of Mwandi District of Zambia and Eastern Zambezi Region of Namibia.
The Zambezi Basin is considered vulnerable to climate variability as evidenced by the recurrent floods. The increased occurrence and severity of floods in recent years in areas previously not flooded has inundated parts ...
Development of updated design norms for soil and water conservation structures in the sugar industry of South Africa.
Sugarcane in South Africa is grown on wide-ranging soils, sometimes in non-ideal climates and on steep topographies where soils are vulnerable to erosion. A consequence of unsustainable soil loss is reduction in field ...
