Les pratiques agropastorales présentent à la fois des effets positifs et négatifs sur la régénération des agroécosystèmes. Cette étude a pour objectif de déterminer l’effet des fèces de différents ruminants sur la dissémination et la germination des espèces en fonction de leurs traits fonctionnels. Ainsi, les fèces des bovins (Bos indicus), des cap...

Afzelia africana Sm – a multipurpose leguminous tree species – is threatened in West Africa – a climate change hotspot region. Yet, although the impacts of land use on this species dynamics have been widely reported, there is a little literature on the impacts of climate change on its spatial distribution. This study aimed to predict the impacts of...

In sub-Saharan Africa, extraction for daily livelihood needs often results in uncontrolled exploitation of bark and leaves of valuable medicinal and fodder trees. However, overharvesting of bark and foliage can reduce fruit production and threaten reproduction. This study evaluates the impact of combined bark and foliage harvesting on the performan...

Tamarindus indica L. is a multi-purpose tropical species. In West Africa the local people use its leaves daily as a source of food, medicine and income. To prevent the over-exploitation of this species for its use for non-timber forest products, the estimation of foliage production needs to be adressed. This study aimed to (1) assess the effects of...

Biodiversity matters in many aspects for human well-being by providing timber and non-timber products. The most important ecosystems providing these products in West Africa are savannas. In the context of land-use changes, there is an urgent need to understand the impact of land-use on savanna vegetation and biodiversity. This study assesses the im...
Article
In the West African Sudanian regions, people depend on natural products, especially on highly valued species as source of income, fuel wood, food, medicine, fodder for livestock etc. However, land-use management coupled with unsustainable uses of highly valued trees might jeopardize the long-term viability of some species’ populations. Thus, we com...
