Agrochemicals in freshwater systems and their potential as endocrine disrupting chemicals: a South African context
(Elsevier, 2021)South Africa is the largest agrochemical user in sub-Saharan Africa, with over 3000 registered pesticide products. Although they reduce crop losses, these chemicals reach non-target aquatic environments via leaching, spray ... -
Beta diversity of urban floras among European and non-European cities
(Wiley, 2014)Aim Cities represent an ideal study system for assessing how intensive land-use change and biotic interchange have altered beta diversity at broad geographic extents. Here we test the hypothesis that floras in cities ... -
Diversity patterns of plants and arthropods in soybean agroecosystems in the grassland biome of South Africa
(Smujo, 2020)Soybean is widely cultivated in the grassland biome of South Africa (ca. 800 000 ha per annum). Yet the possible effects that large-scale cultivation of soybean has on biodiversity in adjacent habitat are not fully ... -
Drivers of regional crop variability in Chad
(Elsevier, 2020)Highlights • Combines environmental and livelihood data to analyze regional crop production in Chad. • Structural breaks are identified and used to detrend the crop statistics. • Combines quantitative and qualitative ... -
The effect of a large-scale irrigation scheme on the fish community structure and integrity of a subtropical river system in South Africa
(Elsevier, 2016)Large scale irrigation schemes are vitally important for food security in developing countries. This is especially relevant in subtropical countries where there is pressure on their water resources. However, the potential ... -
Influence of physico-chemistry and mineralogy on the occurrence of geohelminths in geophagic soils from selected communities in the Eastern Cape, South Africa, and their possible implication on human health.
(Taylor & Francis, 2014)Geophagic soils from selected communities in Eastern Cape, South Africa were characterised to determine their properties and geohelminth content. The soils were coarse-textured with cation exchange capacity values ranging ... -
Plant and arthropod diversity patterns of maize agro-ecosystems in two grassy biomes of South Africa
(Springer, 2015)Intensive, large-scale cultivation has led to a postulated decrease in biodiversity worldwide, which has been ascribed to fragmentation and degradation of natural habitat bordering crop fields. Maize is the most widely ... -
Understanding gender dimensions of climate-smart agriculture adoption in disaster-prone smallholder farming communities in Malawi and Zambia
(Emerald, 2019)Purpose Through the application of traditional and contemporary feminist theories in gender mainstreaming, the purpose of this paper is to contribute to emergent debate on gender dimensions in climate-smart agriculture ...
