In Africa, rangelands are the major sources of feed for ruminants and constitute about 65% of the total land area which supports 59% of all ruminant livestock (Friedel et al ). The rangelands of Ethiopia are mainly located within the arid and semi-arid agro-ecological zones below 1,Cited by: 2.

Rangeland management strategies. The three key driving forces of vegetation change in semi-arid rangelands—rainfall, fire and grazing—act on various different timescales and cause a range of ecological effects ().A clear distinction can be drawn between short-term vegetation dynamics (for example, caused by a single rainfall or drought event) and longer-term changes, Cited by: This volume is part of the series produced under the international programme for the Ecological Management of Arid and Semi-arid Grasslands of Africa and the Near and Middle East (EMASAR), and deals with the training and education of staff necessary to carry out pasture production and rangeland improvement in southern and E.

These areas receive relatively low overall amounts of precipitation in the form of rainfall or snow (UN, ; MEA ).
Drought, change and resilience in South Africa’s arid and semi-arid rangelands Susanne Vetter Introduction Droughts are a frequent occurrence in South Africa’s arid and semi-arid rangelands and can have severe ecological and economic consequences.1 While these may be short-term and followed by recovery during subsequent years of higher rain.

Land degradation is defined as the temporary or permanent decline in the productive capacity of the land, and the diminution of the productive potential, including its major land uses (e.g., rain-fed arable, irrigation, forests), its farming systems (e.g., smallholder subsistence), and its value as an economic resource.
The definition of Arid and Semi-Arid follows the Agro-Ecological Zones classification of FAO, and elaborated by Jätzhold et al in the Farm Management Handbook of Kenya. In its simplified form it combines temperature and available moisture.

Flexible and opportunistic management practices are required to realise the sustainable economic yield from rangelands. Research highlights Although an extensive body of literature on semi-arid rangeland systems exists, there is.
Researchers in SNRE are doing work that will lead to innovative solutions for agricultural needs in arid and semi-arid regions around the world, including crop production, water and land conservation and reclamation, and food security assessment.
As the International Arid Lands Consortium (of which the UA is a founding member) notes, arid. Rangelands vary from desert shrub to lush grassland, and provide the main fodder source for the national cattle and small-stock herds as well as for wildlife.
The productivity of all the rangelands of South Africa has been deteriorating as a result of inter alia desertification, bush encroachment and the loss of palatable plant species. After a year and a half researching our book on arid and semi-arid land trees, and ecological restoration projects and programs in the world’s drylands, we still like our name for that “unnamed movement” Hawken referred to, namely a restoration culture for the 21 st century.

These zones are harsh habitats for humans. Desertification in the arid regions of Asia is characterized by overgrazing of the rangelands of the Middle East and Central Asia, water erosion of cultivated lands from eastern China to the Mediterranean Sea, and salinization and waterlogging on a large scale in Iraq, Pakistan, China, and the Soviet Union.
semi-arid areas of southern Africa is a function of the existing environmental and climatic conditions coupled with governance, socio-economic, health, education, culture and human demography issues.
Communities in semi-arid regions are characterised by: i) dependence. Introduction of woody plants in silvopastoral systems could be an appropriate land-use for the poor sandy soils of the Mediterranean semiarid zone.
Forage production of four woody fodder species and herbaceous vegetation in relation to plant spacing and animal (sheep) grazing was studied in a silvopastoral system on such a site in Macedonia, northern by: Climate-related hazards are a serious threat to Kenya’s development.
Agriculture, the mainstay of the Kenyan economy, is predominantly rain-fed, making it highly vulnerable to climate change. Droughts are the most common disasters affecting Kenya.

Difficulties associated with the non-alignment of the semi-arid areas and the administrative areas are flagged. A demographic sketch is provided based.
Arid regions by definition receive little precipitation—less than 10 inches (25 centimeters) of rain per year.
Semi-arid regions receive 10 to 20 inches (25 to 50 centimeters) of rain per year. Although the rocks and tectonic features underlying arid regions may not differ from other areas, the landscape is distinctive.and problems in East Africa.
