Abstract:: Farmlands, grasslands, and savannas in semi-arid sub-Sahelian Africa have the potential to store carbon (C) in soil. There is a great need to manage ecosystems to increase C storage in semipermanent soil pools. This will improve soil quality, impede desertification and by reducing atmospheric CO₂ levels, will slow climate change....

Abstract:: Water availability is a critical limiting element in semi-arid ecosystem productivity and presents particular challenges in Sahelian countries such as Senegal. The landscapes are characterized by the presence of two common semi-arid shrubs (Piliostigma reticulatum and Guiera senegalensis), both of which may be important hydraulic regulators in these water-limited ecosystems....

Abstract:: Two native shrub species (Piliostigma reticulatum and Guiera senegalensis) are prominent vegetation components in farmers’ fields in Senegal. However, their role in nutrient cycling and ecosystem function has largely been overlooked. A study including both laboratory and field experiments was conducted to evaluate potential biophysical interactions of the two shrub...

Creator:: Diedhiou, Sire
Abstract:: Piliostigma reticulatum and Guiera senegalensis are two native shrubs that coexist with row crops in parkland systems of the Sahel of Africa. Although permanently green all year around in soil depleted in nutrients and dry for a nine-month period, these shrubs have been largely overlooked. Conventional management of these shrubs...
