The role of farm dams as refugia for aquatic invertebrates in a salinised landscape, south Western Australia
In a salinised landscape farm dams may represent the last truly freshwater surface resource, and therefore provide refuge habitats for the biota of wetlands affected by increasing salinity. One wetland threatened by increased salinity in south-west Western Australia is Lake Toolibin. It is listed …

Estimating farm dam storage using SPOT imagery
… classification was used to identify farm dams and their surface area. Two equations applied to determining the capacity of dams were used to convert surface area to volume. The results showed a similarity between fieldwork and object-oriented classification data for surface area. …

Assessment of co-occurrence of cyanotoxins, toxic metals and anionic surfactants in irrigation water, agricultural soils and food crops
… of the hyper-eutrophic conditions affecting most dams in South Africa. The co-occurrence of multiple stressors in agricultural waters and soils potentially pose a human and animal risk if contaminated water and plants are ingested. The study investigated the co-existence of cyanotoxins, anionic …

Bioaccumulation of microcystins in terrestrial food plants and the development of novel sorbents for monitoring microcystins in irrigation water
… SPATT samplers were deployed in canals and farm dams around Roodeplaat and Hartbeespoort Dam sites. The findings elucidated a good vi correlation between the MCs detected by the two newly synthesized sorbents (ChGLA and ChMWCNT) and grab samples. The detected total MCs for the ChGLA samplers …
