The savanna-woodlands of West Africa have been subject to disturbance by fire, grazing and tree cutting for centuries. Often the disturbance is severe, for instance when a thick patch of 4 m tall perennial grass catches fire late in the dry season or man decides to clear-cut an area. Fortunately ...

Fire, grazing, browsing and tree cutting are major anthropogenic determinants of vegetation patterns in African savannas. In Burkina Faso forest management policies prohibit grazing while recommending annual early fire and selective tree cutting of 50% of the merchantable standing volume on a 20-...

Fuel characteristics, fire behaviour and temperature were studied in relation to grazing, dominant grass type and wind direction in West African savanna–woodland by lighting 32 prescribed early fires. Grazing significantly reduced the vegetation height, total fuel load, and dead and live fuel fra...

In West Africa policies for prescribed early fire and livestock grazing in the savanna woodlands are rarely based on long-term experimental studies. The inherently different management characteristics and their effects on the vegetation dynamics make landscape degradation a contentious issue. The...

Le Projet « Aménagement et exploitation des forêts pour le ravitaillement de la ville de Ouagadougou en bois de feu » (TCP/FAO/BKF/85/011) a donné naissance au projet « Aménagement des forêts naturelles pour la sauvegarde de l’environnement et la production de bois » (PNUD/FAO/BKF/89/011). Ce pro...

Le bois énergie et le charbon de bois couvrent une bonne partie des besoins en énergie domestique dans les pays du Sahel : 92% au Burkina, 86% au Mali, 80% au Niger, 47% au Sénégal, 96% au Tchad, selon une étude de la Fao (1986). Les formations arborées (principalement des savanes) sont, de fait,...
