Schistosomiasis is a vector-borne disease transmitted by freshwater snails and prevalent in rural areas with poor sanitation no access to tap water. Three snail species are known transmit schistosomiasis South Africa (SA), namely Biomphalaria pfeifferi, Bulinus globosus africanus. In 2003, predicted prevalence of 70% was reported tropical climates SA. Temperature rainfall variability can alter schistosomiasis-transmitting snails' development increasing or decreasing their abundance...
Domestic solid fuel combustion remains a key contributor to indoor and ambient air pollution in low-income settlements. Understanding solid-fuel cost perceptions burning patterns variability is required for developing sustainable energy policies applicable site-specific intervention strategies effectively improve quality. The purpose of the study was understand domestic use dynamics trends KwaDela, residential area Mpumalanga. Data were gathered using surveys, questionnaires, observations,...
Residential burning of solid fuels is a major source fine particulate matter (PM2.5), which degrades indoor and ambient air quality in low-income settlements. The adverse impact emissions on the environment human health well-documented other countries such as China India; however, there need for local studies to report emission factors from residential fuels. An factor quantifies total mass pollutant emitted per amount fuel burned. Emission an input parameter modelling forecast...
Abstract. Schistosomiasis remains the most endemic disease in tropical regions. Transmission rates and prevalence of schistosomiasis Africa are relatively high compared to other This is mostly associated with lack clean water sanitation as necessities curbing spread disease. Over 90% people sub-Saharan (SSA) deprived sanitation. 60-80% children South African communities infected. Climate variability plays a role distribution vector-borne diseases by affecting intermediate host reproduction...
Alterations in atmospheric temperature and rainfall have a major influence on the distribution patterns of vector-borne diseases, including schistosomiasis, by changing optimum habitat intermediate hosts (vectors) that transmit these diseases. Water quality degradation creation artificial freshwater habitats may widen or restrict disease vectors. Understanding water ecosystems is essential determining environments vectors thrive where potential outbreaks they carry will occur. This study...
High concentrations of the ambient particulate matter remains a concern on South African Highveld, particularly in densely populated low-income settlements. These areas have several local emission sources that contribute to poor air quality and are often located close industrial other urban areas. The vary magnitude, space, time. In Africa, little has been done assess impacts spatiotemporal variability credibility using isolated observations for regulatory purposes. This study aims evaluate...
Water quality degradation and artificial freshwater habitats can affect the distribution of disease vectors. Understanding impact water on ecosystems is crucial in determining where potential outbreaks diseases may occur. The study assessed changes variables between 1977-2009 Mbombela river systems how this have affected presence schistosomiasis Historical data for Sabie, Kaap, Komati Crocodile rivers were obtained from Department Sanitation monitoring stations separated into three decades...
About 70% of the roads in low-income settlements are unpaved and close (≤15m) to residents, thus a major source ambientand indoor PM10 concentrations. International studies have suggested that decreasing vehicle speed managing type onpaved or can reduce dust emissions. These mitigation strategies should be examined before being adoptedand gazetted into South African air quality management plans. This study aimed characterise traffic, emphasisingdetermining impact on GIS was used determine...
On-road vehicle particulate matter (PM) emissions in South African low-income residential areas contribute between 4-16% towards ambient and 9-55% indoor concentration. The lack of field-derived road PM emission factors limits the knowledge required to model understand on-road traffic source contribution toward exceedances areas. study aim is quantify dust per type on paved unpaved roads determine impact meteorological emissions. objectives are characterise within using GIS. To classify...
