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. ...
The effect of trees on preferential flow and soil infiltrability in an agroforestry parkland in semiarid Burkina Faso
Water scarcity constrains the livelihoods of millions of people in tropical drylands. Tree planting
in these environments is generally discouraged due to the large water consumption by trees, but this view
may neglect their ...
Cereal yield response to conservation agriculture practices in drylands of West Africa: A quantitative synthesis
To address the decline in crop productivity in the drylands ofWest Africa, many initiatives have focused on
combating soil degradation. Various practices including (1) parkland trees associated with crops, (2)
coppicing ...
Population structure and regeneration status of Vitellaria Paradoxa (C. F. Gaertner) under different land management regimes in Atacora department
Vitellaria paradoxa (shea) parklands are one of the major features of the Sudanian savannah. Besides the parklands importance in terms of provision of ecosystem services, they play a major role in satisfying household ...
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 ...
Parklands for buffering climate risk and sustaining agricultural production in the Sahel of West Africa
In the Sahelian zone of West Africa, crops grown under a
discontinuous cover of scattered trees dominate many
landscapes and constitute the so-called parklands. These
systems reflect the ecological knowledge of the farmers ...
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 ...
Length of Growing Period over Africa: Variability and Trends from 30 Years of NDVI Time Series
The spatial distribution of crops and farming systems in Africa is determined by the duration of the period during which crop and livestock water requirements are met. The length of growing period (LGP) is normally assessed ...
