Maize is a staple crop important for food security that millions globally depend upon as an
energy source, primarily due to its high starch and fat content. For growth and disease resistance,
maize production requires a ...

Nitrogen oxides, particularly NO2, are emitted through a variety of industrial and transport
processes globally. The world’s continuous economic development, including in developing countries,
results in an increasing ...

Wetlands face global threats with estimates suggesting a loss ranging from 21% to 85% of their original extent.
Africa’s wetlands, covering about 4.4% of the continent, provide crucial services to millions of people and ...
NON-TECHNICAL SUMMARY. Greenhouse gas emissions and land use change – from deforestation, forest degradation, and agricultural intensification – are contributing to climate change and biodiversity loss. Important land-based ...
Biomechanical and orthopaedic studies frequently encounter complex datasets that encompass both circular and linear variables. In most cases (i) the circular and linear variables are considered in isolation with dependency ...
Radical and quick transformations towards sustainability will be fundamental to achieving a more sustainable future. However, deliberate interventions to reconfigure systems will result in winners and losers, with the ...
Africa is experiencing widespread extreme precipitation. However, the continent remains understudied regarding extreme precipitation variation, particularly at high temporal resolution. This study assessed the changes in ...
A soil seed bank is the collective name for viable seeds that are stored naturally in the soil. At the species or population level, the ability to form a seed bank represents a strategy for (re)colonization following a ...
Climate change has massive global impacts and affects a wide range of species. Threatened species such as the roan antelope (Hippotragus equinus) are particularly vulnerable to these changes because of their ecological ...

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 ...
