The effect of land-use on the vegetation communities along a topo-moisture gradient in the mid-Fish River valley, South Africa
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: N.V. Birch A.M. Avis A.R. PalmerThe objectives of this study were to identify the major physical environmental variables affecting plant community distribution, and to determine whether a shift occurred in plant community position along an environmental gradient of different land-use practises. To achieve these objectives... -
Syndromes of dryland degradation in southern Africa
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: RJ Scholes --- Natural Resources and the Environment, South AfricaDryland degradation (in other words, desertification) is defined for the purposes of this paper as a persistent decrease in the capacity of an arid or semiarid ecosystem to supply a range of services, including (but not restricted to) forage, fuel,... -
A conceptual tool for improving rangeland management decision-making at grassroots level: the local-level monitoring approach
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: K Kellner --- School of Environmental Sciences and Development, South Africa AS Moussa --- School of Environmental Sciences and Development, South AfricaFor many years, rangeland monitoring has mainly been the field of scientists, academics and extension workers trying to fine-tune methods to assess the condition of rangelands. Frameworks and monitoring systems developed with their associated indicators are often complex and inaccessible... -
Institutions for sustainable land management: reflections on institutional aspects of implementing the UNCCD in South Africa
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: G von Maltitz --- Natural Resources and the Environment, South AfricaBy its nature, combating desertification is a complex, multidisciplinary activity that requires coordinated responses at a multitude of levels spanning both scientific disciplines and government departments. In the final analysis, it is at the level of the land user where... -
The development of reforestation options for dryland farmland in south-western Australia: a review
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Richard J Harper --- School of Veterinary and Life Sciences, Australia Stanley J Sochacki --- School of Veterinary and Life Sciences, Australia John F McGrath --- School of Veterinary and Life Sciences, AustraliaCurrent forest industries in south-western Australia are based on regrowth natural eucalypt forests and Pinus and Eucalyptus spp. plantations, and restricted to areas with >600 mm y−1 annual rainfall. Dryland farming systems have been developed across 20 million ha in... -
Long-term changes in land use, land cover and vegetation in the Karoo drylands of South Africa: implications for degradation monitoring
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: M Timm Hoffman --- Department of Biological Sciences, South Africa Andrew Skowno --- South African National Biodiversity Institute, South Africa Wesley Bell --- Department of Biological Sciences, South Africa Samukele Mashele --- Department of Biological Sciences, South AfricaWe used several large data sets at a range of temporal and spatial scales to document the land-use/land-cover change (LULCC) dynamics of the semi-arid Succulent Karoo and Nama-Karoo biomes of South Africa. More than 95% of the Karoo is comprised...
