Approximately 89% of the rural households in Sudan rely on biomass, such as fuel wood, charcoal, agricultural wastes to meet their energy needs for cooking
•UNEP estimates that fuel wood requirements for 2006 were around 27 to 30 million cubic metres.
•"UNEP predicts that within five to ten years, the northern states of Sudan will only be able to obtain sufficient supplies of charcoal from Southern Kordofan and Darfur as all other major reserves will have been exhausted,
Many regions of Northern and Western Darfur are undergoing desertification and land degradation at a significant rate.
Other states facing similar issues are Southern Kordofan, eastern Kassala, northern Blue Nile, northern Upper Nile and northern Unity state.
Area of the study The target area is West Kordofan State Livestock is estimated at 465,000 cattle, 22,265,000 sheep, 2,064,000 goats and 747,000 camels.
The area suffers from illicit woodcutting deforestation problems; inadequate aforestation activities.
