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 ...

Decentralization initiatives are on-going in many developing countries. In Burkina Faso, the government has embarked on a long-term decentralization effort that groups rural villages into self-governing communes with the capacity to plan their own development programs. Nearly two decades before t...

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 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,...

This study examines challenges associated with early stages of decentralizing the administration and management of forest resources in the Centre-West Region of Burkina Faso. It is based on fi eldwork using rapid rural appraisal, focus group discussions and interviews with key stakeholders, metho...

Smoke generated by burning of plant materials has widely been recognized as a germination cue for some species from both fire prone and fire-free ecosystems. It is an important factor for the understanding of vegetation dynamics and could have potential use for ecological management and rehabilit...
