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. ... -
Estimation of reference evaporation and comparison with ET-gage evaporimeter
(2003)Accurate estimation of reference evaporation is necessary for the estimation of actual evaporation for irrigation and water resource management purposes. Estimation of reference evaporati~n using the Penman-Monteith method ... -
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 ... -
Investigating possible impact of climate change on sugarcane production in KwaZulu-Natal, South Africa.
(2016)The KwaZulu-Natal Department of Agriculture, Environmental Affairs and Rural Development in 2010 undertook to investigate the vulnerability of KwaZulu-Natal to climate change which identified various sectors of the economy ... -
Irrigation control system with a web-based interface for the management of Eucalyptus planting stock.
(2015)Commercial forestry nurseries use large quantities of water to irrigate the planting stock to meet the annual forestry industry planting demands. However, South Africa is a water scarce country and there is high competition ... -
The long-term measurement of total evaporation over Acacia mearnsii using large aperture scintillometry
(2007)A large aperture scintillometer (LAS) was operated continuously over a distance of 575 m from 19 August 2006 to 29 September 2007 in the South African KwaZulu-Natal midlands mistbelt area over Wattle (Acacia mearnsii). The ... -
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 ... -
Microclimate modification to improve productivity of ‘Carmen®-Hass’ avocado orchards using shadenet under subtropical conditions of Limpopo Province, South Africa.
(2016)The agricultural environment is a complex and dynamic system. Microclimate, the crop, biosphere, and management practices interact to determine the best yield production. South Africa is a water-scarce country, with high ... -
Modelling the impacts of increased air temperature on maize yields in selected areas of the South African highveld using the cropsyst model.
(2014)Abstract available in PDF file. -
Monitoring fire danger in near real-time using field-based agrometeorological measurement systems.
(2014)Africa has been termed the ‘Fire Continent’ due to its high annual fire frequency. Wildfires are considered one of the most common disasters in South Africa resulting in a high number of human fatalities and financial loss ... -
The radiation balance of Midmar Dam in KwaZulu-Natal, South Africa.
(2016)Abstract available in PDF file. -
Rainy season characteristics with reference to maize production for the Luvuvhu river catchment, Limpopo Province, South Africa.
(2017)In arid and semi-arid regions, crop yields are mainly dependent on the amount and spatio-temporal distribution of rainfall. For most smallholder farmers in rural areas of southern Africa, rainfall is a critical input to ... -
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 ... -
Runoff simulation using the SWAT model for flood frequency analysis and design flood estimations in the Luvuvhu River catchment, South Africa.
(2018)Abstract available in PDF file. -
Seasonal variation of surface energy fluxes above a mixed species and spatially homogeneous grassland.
(2011)The increasing human population, industrialization, urbanisation and climate change challenges have resulted in an increased demand for already scarce water resources. This has left the agricultural sector with less water ... -
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 ... -
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 ... -
Temperature dynamics within a low-cost aquaponic system and the possibe effects of climate change.
(2019)The agricultural sector is facing impeding challenges due to climate change. There is enough evidence showing that climate change has a significant impact on agricultural production. Marginalized communities that lack ... -
The use of infrared thermometry for irrigation scheduling of cereal rye (Secale cereale L.) and annual ryegrass (Lolium multiflorum Lam.)
(2003)Limited water supplies are available to satisfy the increasing demands of crop production. It is therefore very important to conserve the water, which comes as rainfall, and water, which is used in irrigation. A proper ... -
Using agrometeorological data to equip local farmers for sustainable food production in Swayimane, KwaZulu-Natal.
