Agricultural adaptation to intensifying El Niño and La Niña periods within North West, South Africa
(North-West University (South Africa), 2021)Climate can be defined as the mean and variability of the relevant atmospheric parameters such as temperature, precipitation and wind over a long period of time. These parameters fluctuate over time, creating different ... -
Biodiversity and ecological structures of an African subtropical river and associated floodplain pans
(North-West University (South Africa), 2019)Although only recently added to the many existing threats that freshwater ecosystems already face, climate change is one of the most prominent to inland waters in the 21st century. Through extended periods of drought and ... -
Competency of extension agents on climate smart agricultural initiatives in South Western Nigeria
(North-West University (South Africa), 2019)The effect of climate change has posed a great challenge to the survival of the human race and agriculture and the competence of extension agents in the effective dissemination of climate smart agricultural initiatives ... -
A critical review of the consideration of climate change risks and opportunities in Environmental Impact Assessments (EIAs)
(2014)It is widely acknowledged that the impacts of climate change are likely to be far worse than some people believe possible. Research has shown that our current approach and intervention to combat climate change is hopelessly ... -
A critical review of the consideration of energy alternatives in environmental impact assessment (EIA)
(North-West University, 2010)Climate change, as well as the recent energy crisis in South Africa, has placed renewed emphasis on the need to consider alternative energy options for future developments. EIA can and should play an important role in ... -
Drought effects on the herbaceous community structure of transformed Mopaneveld
(North-West University (South Africa), 2020)Semi-arid Mopaneveld vegetation structure is driven by herbivory, fire, nutrients and rainfall variability. The floristically homogenous herbaceous layer is highly dynamic and dominated by forbs. Forb species contribute ... -
Ecotoxicological assessment of aflatoxin in soil under different temperature and moisture conditions utilising earthworms
(North-West University (South Africa), 2022)Aflatoxins are secondary metabolites produced by specific strains of fungi. These natural toxins are mainly found in soil, decaying vegetation, and food storage systems and are particularly abundant during drought stress. ... -

(North-West University (South Africa), 2023)Climate change is a global phenomenon that has various effects on the agricultural industry. The Department of Agriculture, Forestry, and Fisheries identified maize as the most important grain crop in the country, as it ... -
Effects of increased heat and drought stress approximating climate warming on the reproduction, photosynthesis and growth of Proteaceae species in a southern African Mediterranean climate ecosystem
(North-West University (South Africa), Potchefstroom Campus, 2016)In this research project, the effects of warming and drought on three Proteaceae species (Protea repens, Protea laurifolia, Leucadendron laureolum) were investigated through various monitoring and experimental studies on ... -
Effects of Temperature and Moisture on the Ecotoxicity of Metal-Based Fungicides Towards Earthworms
(North-West University (South Africa), 2022)Climate change is a major threat to biotic and abiotic ecosystems worldwide and might potentially affect the mobility and bioavailability of metals in soil. Anthropogenic activities such as mining, agriculture and the use ...
