Institute of environmental studies
In 1977, the United Nations University (UNU) had taken a special obligation to foster the growth and interaction of Third World research and training institutions. Given the considerable global concern regarding the degradation of dryland environments, Sudan was recommended by UNU for implementing arid zone resource management, being the largest country in Africa, with two thirds of its land being regarded as arid zone with a range of traditional livelihoods from irrigation to pastoralism. Sudan is also a crossroads of African environments, linked northwards to Egypt by the Nile through a series of physical and cultural environments. Sudan is also a joined east west through the Sudano-Sahelian belt by patterns of migration and cultural interaction.
