The impact of climate change on degradation of natural vegetation in semi-arid areas Study of the regions of North
Kordofan and eastern Elbotana - Sudan

The natural vegetation is an important source for humans, particularly with respect to its requirements basic food and drink and the air and fuel and other There is no other supplier of natural resources has so much advantages diverse and important to humans, Plants natural source for many drugs as they source for many products cash and food, This is the source of gum arabic, which is one of the most important products in cash Sudan. The study research and analysis of climate change and its impact on the vegetation in semiarid areas in the Sudan during the period (1970-2007 AD) and the reasons that led to the degradation of natural resources.
To apply Atraltgarat climatic vegetation in semi-arid areas have been selected two regions in Sudan are Eastern lining and North Kordofan, the occurrence of zones of study within the scope of climate semi-dry them like other areas African coast exposed to droughts as a result of climate fluctuations in recent years, He played Alhvav a key role in the lack of vegetation and depletion of water resources and the decline of agricultural areas and thus reflected negatively on the economic aspects of private and regions study was characterized by a series of natural vegetation varied vary in their diversity by rainfall, but the drought that prevailed in the region since 1984 breached distributing those plants because of the lack of rain and the changing climatic conditions and human practices unjust wrong pieces in the region has led to increased drought The impact in turn on decaying vegetation, which reflected negatively on the yield of the area of water resources and changing land use systems.
Search follows an analytical synthesis approach in the application of models in the decision to change or reorganize the pattern of land use. And was based on this model to several Muslims, as well as maps and satellite images and weather, and reports of governmental and non-governmental organizations, adopted research primarily on preliminary information gathered from the regions to search through field work and have been used for observation of the work of different measurements, including: plant Natural (pasture), the pattern of land use and productivity. And to analyze this information and its interpretation and to clarify this information and show in different forms of charts and graphs and maps and rely on several computer programs, statistical programs, program Erdas) for the analysis of images of the moons Alsnaaahosthaddam GIS
The study found the following results: -
1 - Climate Change of rising temperatures and the intensity of evaporation and the rule of drought have led to the fluctuation of rainfall and water scarcity in the region, which has had a significant impact on the deterioration of vegetation.
2 - the wrong human practices in land use have led to degradation of vegetation, which helped to soil erosion has been reflected on the agricultural production in the region.
3 - Plant deterioration to low livestock sector and the low yield than in the study area.
The study put some recommendations to reduce those risks, including: Develop a plan for sustainable development through:
- Plant Ttaiwiralgtae and maintain it through the establishment of an integrated project includes harvesting and dissemination of water and forest afforestation pastoral and pastoral farms.
