Since grassland is commercialized through the grazing animal, particular attention is paid to the livestock production systems associated with each main type.
Grazing resources are more than simply edible herbage: many other factors. In South Africa, the agricultural sector plays a signiﬁ cant role in the country’s economy. Anecdotal evidence suggests that climate change could lead to a fall of about % in the country’s GDP by – a fall roughly equivalent to the total annual foreign direct investment in South Africa at present.
Land Degradation and Improvement in South Africa i MAIN POINTS 1. Land degradation is a global environment and development issue.

South Africa is especially susceptible to IAPs and this is nationally perceived as the country’s greatest land degradation threat, partly because it reduces national streamflow by %, with far higher hydrological impacts in some of the country’s critical catchments (Le Maitre et al., ; Richardson and Van Wilgen, ).The Fynbos and grassland biome are exceptionally Author: Graham Paul von Maltitz, James Gambiza, Klaus Kellner, Thizwilondi Rambau, Lehman Lindeque, Barney K.

The aims of the. Continued degradation of rangelands will have a far-reaching impact on the environment. According to a report titled “Carbon Finance in Rangelands: An assessment of Potential in Communal Rangelands” rangelands are the largest land use type, covering about 40% of the world’s land surface and have the potential to play a big role in carbon.
Nutritious perennial grass species including Eragrostis pallens Hack. Ex Schinz remain prevalent in Wildlife Management Areas. Other ecological changes include the invasion of the exotic Prosopis glandulosa Torr. and dense stands of Rhigozum trichotomum Kuntze. The overall value of rangeland in South Africa is reflected by the annual value of commercial livestock production estimated to be ZAR 18 billion (Meissner et al.
), that of the commercial wildlife industry ZAR 10 billion (Department of Environmental Affairs b), and that 19 million people reside in rural by: Southern Africa: Facts Most people (70%) live in rural areas and depend on subsistence agriculture for their livelihoods.
They depend on land for agricultural production or for conservation (parks or conservancies). A large area in the region, equivalent to 70% or more, is arid or semi-arid while part of it is complete desert. Understanding Rangeland Biodiversity.

In Namaqualand, heavy grazing of low-lying areas has resulted in the reduction of palatable perennial shrubs and the dominance of the unpalatable shrub, Galenia africana.

It is now widely accepted that the global climate is changing. The impact of climate change will differ across and within regions. It is anticipated that Southern Africa will experience higher temperatures, with increases expected to range from °C to 3°C; the region will also experience more hot days and fewer cold and frost.
Biodiversity is important for South Africa because of its importance in maintaining ecosystem function, the proven economic value of South Africa’s biodiversity resources, and its role in supporting subsistence lifestyles. Aspects of ecosystem health such as sustained primary production, soil retention, and water yield and water.

Forests, Rangelands and Climate Change Adaptation in Southern Africa • FAO in collaboration with the SADC secretariat organized a workshop with SADC member states to 1) take stock of countries’ current efforts related to forests, rangelands and climate change and 2).
Climate change is expected to adversely affect agriculture in South Africa. A rise in variable and unfavourable conditions is likely to surpass the limits of current coping mechanisms of farmers, compelling them to implement more resilient adaptive measures to decrease their vulnerability to heightened risks.
Downloadable. Residents of Southern Africa depend on rangeland for food, livelihoods, and ecosystem services. Sustainable management of rangeland ecosystems requires attention to interactive effects of fire and grazing in a changing climate. It is essential to compare rangeland responses to fire and grazing across space and through time to understand the effects of rangeland.
