Introduction. Gum Arabic, which has countless applications, is a nontimber forest product of Acacia trees, namely Acacia senegal and Acacia seyal, of the Sudano–Sahelian region of sub-Saharan Africa (JECFA, , Karama, ).More than hundred species exist of the genus Acacia that produce natural gums (Beyene, ).However, gum from A. senegal and A. seyal is considered to be of high Author: Zeinab Mohamed Hammad, Mohammed Hamed Mohammed. The giraffe (Giraffa) is an African artiodactyl mammal, the tallest living terrestrial animal and the largest is traditionally considered to be one species, Giraffa camelopardalis, with nine r, the existence of up to eight extant giraffe species has been described, based upon research into the mitochondrial and nuclear DNA, as well as morphological measurements of Class: Mammalia. The results revealed that great changes have been taken place in quantity and quality of natural vegetation towards negative trends according to respondentsâ€™ views. Majority of interviewees agree that the disappeared vegetation types were more palatable to livestock. The lack of precise, agreed estimates of the extent of desertification opens the door to misusing the concept. For instance, figures portraying a dramatic image of desertification have proved very popular among politicians seeking to attract international funds (Thomas, ).A recent review of most important newspaper headlines (Reynolds and Stafford Smith, ) showed the radical treatment.

Mohamed Elamin Abdelrahman, Sudan. Nov. Key Words: Land- In its broader sense as defined by FAO(), comprises the physical environment, including climate, relief, soils, hydrology and vegetation, to the extent that these influence potential for land use. Africa is an important part of the global carbon cycle. It is also a continent facing potential problems due to increasing resource demand in combination with climate change-induced changes in resource supply. Quantifying the pools and fluxes constituting the terrestrial African carbon cycle is a challenge, because of uncertainties in meteorological driver data, lack of validation data, and Cited by: p. Colloquium on Pastoral Economies in Africa and Long-Term Responses to Drought, Aberdeen (UK), Apr Reviews the current area of concern and debate in Africa, that is, the question of long-term responses to drought in African pastoralist societies or in mixed economies with a significant element of pastoralism.
Recent changes in land use, especially expansion of mechanized farming in Southern, Blue Nile and Southern Kordofan have been at the expense of forests and woodlands. 2. Sudan forest resources. According to the FAO, forest area decreased from 34 percent in . Khatir ARAI.

Browse is not considered as important a component of animal diets in the subhumid zone as in the Sudanian and Sahelian zones because of the number of woody species acceptable to stock is limited and. The Sudan’s First National Communication (SFNC) predicted that there will be a significant decrease in agricultural productivity and a reduction in gum Arabic belt in Kordofan in the future (, medium and long –term).
