A region is arid when it is characterized by a severe lack of available water, to the extent of hindering or preventing the growth and development of plant and animal life. Environments subject to arid climates tend to lack vegetation and are called xeric or "arid" climates straddle the Equator; these places include parts of Africa, Asia, South America, Central America, and. ‣Rangelands are usually semi-arid to arid and include grasslands, tundra, scrublands, coastal scrub, alpine areas, and savanna. ‣ Rangelands cover about 50% of the Earth’s land surface. ‣ Rangelands are often used for grazing livestock, but because they often occur in low rainfall areas they do not regenerate quickly. Managing Rangelands ‣ Grasses grow continuously from a meristem. Recently published articles from Journal of Arid Environments. Recently published articles from Journal of Arid Environments.

Overgrazing by livestock is the principal land problem in the arid and semi-arid regions, coupled with land use change to cultivated farmland in the many countries (Barrow ).

In its simplified form it combines temperature and available moisture. Temperature in the map units directly relate to altitude, which makes the system less reliableFile Size: 1MB.
Definitions • Drylands cover approximately 40% of the world’s land area, and support two billion people, 90% of whom live in developing countries.
These areas receive relatively low overall amounts of precipitation in the form of rainfall or snow (UN, ; MEA ). Dry areas (arid, semi-arid and dry sub-humid zones) cover 52 million square kilometres — more than one third of the globe's land surface. Most of this is rangeland, where annual winter rainfall is less than millimetres, or desert, where it is less than millimetres.
woody parameters in rangeland condition rating can be useful in evaluating rangelands. In arid and semi-arid rangelands heavy grazing pressure and climatic factor such as elevation can influence forage production and shift composition (Amsalu and Barrs, ; Gemedo-Dalle et al.,).
surveys based upon sound ecological basis performed by expert range specialists and managers. Introduction The arid and semi-arid rangelands of the world are the lands between cropping zones and the deserts.
They are too rocky, often have shallow soils, expand under harsh. The semi-arid zones of the world are fragile ecosystems which are being sub stantially modified by the activities of mankind.
Increasing human populations have resulted in greater demands on semi-arid zones for providing human susten ance and the possibility that this may enhance desertification Format: Paperback.
However, agricultural managers presently consider that changes in vegetation community structure, notably a gradual increase in bush dominance and changes in the mix of palatable and unpalatable grasses, are the main threat to sustainable cattle production on many semi-arid rangelands (Warren and Agnew, ; Dougill and Cox, ).Cited by: Recent ecological studies in semi-arid rangelands have shown that developing sustainable agriculture will depend on an improved understanding of the spatial and temporal varia-bility characterizing semi-arid ecosystems (Behnkeet al., ; Scoones, ).
Ecologi-cal reviews (e.g., Scholes and Walker, ; Belsky, ) portray semi-arid. Pastoralism was for many years the traditional land use in the Arid and Semi-Arid Lands (ASAL) zone of Kenya. These rangelands comprise about 85% of the country and accommodate around 28% of the total human population.

Searching for new indigenous species to help in the reclamation of arid zones is of the utmost importance.

september, Responses of forage production to precipitation, but not foliar and basal cover, were similar for the three semi-arid ecosystems.
Total forage production was more responsive (75–%) than basal (8–35%) or foliar (2–29%) cover to increasing by: Section 3 selects a definition for the semi-arid areas in Tanzania, and identifies the two distinct semi-arid resource zones that follow from this definition.

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. The majority of the major shortfalls in food supply recorded have been associated with rainfall deficits.

Author: David J. Tongway. The semi-arid and dry sub-humid areas of West Africa experience strong inter-annual and inter-decadal climate variability. The region also has a high exposure to dry spells and drought and over the past 50 years there has been significant land degradation, which exacerbates impacts of extreme climate events.

Unfortunately, these agronomic techniques alone a re insufficient for sustainable development of semi-arid Africa. Socio-economic. The overall objectives of the project are to: (a) conserve the arid land adapted animal and plant biodiversity of the transboundary range and grazing lands common to Mozambique, Zambia, and Zimbabwe by improving community-based resource management; and (b) improve the quality of rural livelihoods through diversified and sustainable natural resource use and biodiversity protection.
Rangeland Ecology, Forage and Management 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.
assessing diet selection and resource partitioning amongst livestock in semi-arid rangelands. Project Methods Because semi-arid rangeland ecosystems often exhibit nonlinear dynamics, we will use the state-and-transition model theory as a conceptual underpinning to study plant community attributes and key ecological processes involving C, N and water.
C, N and water processes will be studied to provide insight into potential mechanisms that govern changes between states of.
