Application of crop models in assessing impact of climate change and identifying adaptation options in a tropical environment in Ethiopia.
(2021)Abstract available in PDF. -
Observed and projected climate change effects on localized drought events: a case study for sugarbelt within KwaZulu-Natal Midlands, South Africa.
(2021)The projected increase of air temperature across the globe has been associated the increased vulnerability of resource-poor farming communities to climate variability. Past and possible changes in climate trends for the ... -
Analysis and integration of regional scale temperature datasets into a seasonal crop monitoring system.
(2018)Populations in excess of 20 million people in southern Africa annually face food insecurity. This number increases appreciably when detrimental seasonal climate conditions lead to widespread reductions in crop harvests. ... -
Variability of radiation balance in sloped terrains and its impact on microclimatic characteristics of field crops.
(2018)Abstract available in PDF file. -
The respiratory health effects associated with particulate matter (PM₂․₅) exposure in children residing near a landfill site : a case of eThekwini Municipality.
(2015)Currently, land-filling is the main waste disposal method utilized in South Africa. However little is known about the health risk factors among children living near the landfill sites. This is a first study that sought to ... -
Measurement of water potential using thermocouple hygrometers.
(1982)Theory predicts that the time dependent voltage curve of a thermocouple psychrometer where there is no change in output voltage with time during the evaporation cycle defines the wet bulb temperature T[w] corresponding ... -
Heat and energy exchange above different surfaces using surface renewal.
(2008)The demand for the world’s increasingly scarce water supply is rising rapidly, challenging its availability for agriculture and other environmental uses, especially in water scarce countries, such as South Africa, with ... -
Potential for using trees to limit the ingress of water into mine workings : a comparison of total evaporation and soil water relations for eucalyptus and grassland .
(2003)Current mining methods used to extract coal from underground mine workings disturb the natural environment and the existing stable geological structures. As a result, the ingress of water into the mines increases and the ... -
Long-term measurements of spatially-averaged sensible heat flux for a mixed grassland community, using surface layer scintillometry.
(2007)Evapotransipration by vegetation cover is an important component of the water budget and energy balance in any ecosystem. A key to more improved water management therefore lies in improving our understanding of ... -
Sensible heat flux for estimating evaporation.
(2010)The focus of the research is on investigations of various methods for obtaining sensible heat flux (H) for estimating evaporation. The key for this approach is the application of the shortened energy balance equation, and ... -
Sensible heat flux under unstable conditions for sugarcane using temperature variance and surface renewal.
(2010)Increased pressure on the available limited water resources for agricultural production has a significant impact on sugarcane production. Routine monitoring of evaporation with reliable accuracy is essential for irrigation ... -
Sensible heat flux and evaporation for sparse vegetation using temperature-variance and a dual-source model.
(2010)The high population growth rate and rapid urbanization that the world is experiencing today has aggravated the competition for the already scarce resource ¡V water ¡V between the agricultural sector and the other economic ...
