About the Book

Depuis les années 1960, une campagne ininterrompue a été menée pour fournir de l'eau potable aux hommes et au bétail dans tout le Kordofan et le Darfour. Les sources d'eau permanentes établies par le gouvernement et les donateurs internationaux n'ont pas été accompagnées d'un inventaire de l'aire de répartition afin de décider si les densités de peuplement dans les zones suggérées pour l'établissement de nouveaux trous de forage ou de hafirs étaient appropriées. La situation nouvellement créée a conduit à un surpeuplement qui a entraîné les conséquences suivantes: 1- Changement radical de la composition des plantes de l'aire de répartition, de la capacité de charge, de la fréquence des espèces et de leur densité. 2- L'accentuation de l'avancée du désert. 3- Conflits entre les nomades et entre les nomades et les agriculteurs. 4- Le déplacement de certains groupes de nomades et leur intégration dans la vie urbaine. Le développement intensif et la répartition inégale des sources d'eau dans la zone de savane à faible pluviosité (État du Kordofan occidental) ont exercé des pressions sur l'écologie fragile de la zone. Ces pressions auraient dû conduire à des changements dans la composition des plantes de l'aire de répartition, la fréquence des plantes, la densité des espèces et les capacités de charge. Tous ces changements observés n'ont jamais été évalués.
