What induced farmers to protect and manage on-farm tree natural regeneration in Nigerien Dryland?
During the second half of the 20th century the Sahel experienced one of the most striking shifts in climate known globally since instrumental records began to be kept-from anomalously abundant rains in the 1950's and 1960's ...
Ecosystem management can mitigate vegetation shifts induced byclimate change in West Africa
tThe welfare of people in the tropics and sub-tropics strongly depends on goods and services that savannaecosystems supply, such as food and livestock production, fuel wood, and climate regulation. Flows ofthese services ...
Comparison of aboveground vegetation and soil seed bank composition at sites of different grazing intensity around a savanna-woodland watering point in West Africa
Grazing removes a plant’s aboveground vegetative and reproductive tissues and can modify the soil seed bank, potentially impacting the restoration of preferred species. Knowledge about aboveground vegetation and species ...
Relationships between soil seed banks and above-ground vegetation along a disturbance gradient in the W National Park trans-boundary biosphere reserve, West Africa
Aims
Vegetation succession depends on the availability of suitable propagules
in the soils, thus knowledge of soil seed banks is essential
for formulating effective strategies for restoring the vegetation of
degraded sites. ...
Farmers’ awareness and perception of climate change impacts: case study of Aguie district in Niger
The agricultural sector is the main source of rural households’ food and revenue in Niger, and it contributes approximately 43% to the national GDP. However, there are several constraints to the sector’s development, ...
Factors influencing conservation of trees on farmland and silvicultural management activities in a Sudanian agro-ecosystem, West Africa
The loss of tree resources and low productivity of soil are the main environmental problems
affecting the livelihoods in developing countries. This paper reports a study of factors
influencing farmers’ decision to protect ...
Régénération des arbres et amélioration des moyens de subsistance des petites exploitations agricoles en zone semi-aride dans l’Ouest du Burkina Faso
Dans un contexte marqué par les changements climatiques et une forte croissance démographique, les petites exploitations agricoles en Afrique subsaharienne restent confrontées au défi d’une production alimentaire suffisante ...
Perspectives in restoration: storage and pretreatments of seeds for better germination of Sudanian savanna-woodland species
Insufficient knowledge of the germination
ecology of local species is one of the main constraints to
restoration of degraded rural lands. We tested seeds from
fourteen Sudanian savanna species targeted for restoration
for ...
Expanding networks of field hedges in densely populated landscapes in the Sahel
Changing woody plant density across agricultural landscapes of the Sudano-Sahelian region is a debated issue. This paper reports the results of an investigation on the contribution of field hedges to overall woody plant ...
Rôle des feux de savane sur les caractéristiques biogéochimiques des sols en zone soudanienne du Burkina Faso
Les feux de brousse dont les effets dépendent aussi bien de leurs intensités ainsi que de leur saison
d’occurrence, sont considérés comme une perturbation écologique majeure des écosystèmes savanicoles.
L’objectif général ...
