The high spatial variability of precipitation, heightened frequency of droughts and concomitant increases in exposure to water stress across southern Africa due to climate change, presents significant challenges for sugarcane ...
Southern African mountain ranges are characterised by rich and diverse plant species thriving
in different habitats with pronounced endemic species. However, globally, biodiversity at the
species level is deteriorating ...

Optimizing the prediction of maize (Zea mays L.) yields in smallholder farming systems enhances crop management and thus contributes to reducing hunger and achieving one of the Sustainable Development Goals (SDG 2—zero ...
This paper examines the factors that impact urban greenspace (UGS) usage in three urban parks in the city of Tshwane, South Africa. Guided by systems theory, we aim to determine how various cultural ecosystem services ...
BACKGROUND : The epidemiological evidence on the interaction between heat and ambient air pollution on mortality is still inconsistent.
OBJECTIVES : To investigate the interaction between heat and ambient air pollution ...
BACKGROUND : Evidence on the potential interactive effects of heat and ambient air pollution on cause-specific
mortality is inconclusive and limited to selected locations.
OBJECTIVES : We investigated the effects of heat ...
Cross-national studies examining the relationship between weather and crime are rare. Reasons are manifold but include the differences in countries due to geographical, climatic, and seasonal variations. In contrast in ...
Despite robust warming trends in surface air temperatures over southern Africa, extreme low temperature (ELT) events still occur from time to time. A recent ELT event affected South Africa resulting in disruptions in ...
INTRODUCTION: Coal-fired power plants are major sources of
air pollution which impact human health. Coal combustion
byproducts released into the air include particulate matter,
nitrogen oxides and sulphur dioxide. ...
Gradient-Boosted Decision Trees (GBDTs), particularly when tuned with Bayesian optimisation, are powerful machine learning techniques known for their effectiveness in handling complex, non-linear data. However, the performance ...

Background
Various local villages in the Vhembe district of South Africa have experienced high
malaria infection rates together with a high variability of malaria case mortality rates over
the past 20 years. This research ...
To tackle the current pressing atmospheric science issues, as well as those in the future, a robust
scientific community is necessary in all regions across the globe. Unfortunately, this does not yet exist. There are
many ...
AIMS: Remote-sensing approaches could be beneficial for monitoring and compiling
essential biodiversity data because they are cost-effective and allow for coverage of
large areas over a short period. This study investigated ...
