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-...

Annual early fire, selective tree cutting and exclusion of grazing are currently used as management tools in the Sudanian savanna of Burkina Faso although their longterm effects on seedling recruitment are poorly documented. A factorial experiment involving fire, grazing and cutting, each with t...

This paper places forestry in the larger context of rural development and therefore in the current debates on poverty and inequality. While Africa has high levels of natural and human capital it is the poorest and most unequal region in the world. In order for natural assets to contribute to envi...

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...

The potential of forest to regenerate after harvesting is a key element for sustainability of the ecosystem. For semi-arid tropical savanna environments, managing resprouts after tree cutting is ideally suited because of the natural ability of many indigenous species to regenerate vegetatively. R...
