Hydraulic redistribution is the process of passive water movement from deeper moist soil to shallower dry soil layers using plant roots as conduits. Results from this study indicate that this phenomenon exists among two shrub species (Guiera senegalensis and Piliostigma reticulatum) that co-exist with annual food crops in Sahelian agro-ecosystems....
Personal health monitoring tools, a subset of point-of care-diagnostics, enable more frequent testing of chronic health conditions outside of a clinic setting and can inform personalized therapy or support telehealth diagnostic capabilities. While there is evidence that regular monitoring of chronic conditions can lead to better health outcomes and lower...
Global Graduates/Oregon International Internship Program offered an internship position working in Senegal with the Institut Senegalais de Recherches Agricoles (ISRA) and the Natural Resource Based Agricultural Research (NRBAR). The author of this paper was accepted for this internship and lived and worked in Senegal from October 1 through December 15,...
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....
The frontlines of climate change adaptation will occur in rural, impoverished regions of the world where households engage in climatically dependent livelihoods, such as peasant agriculture or pastoralism. As changing climate and changing markets affect the suite of household livelihood assets (environmental, social, and economic) which enable a household to...
The wide expanse of the sea, the inter-linkages among, and the productivity of its resources have until recently led most researchers to consider it unrealistic that humans could have more than local impact on marine ecosystems and their biodiversity. This perception is changing, however, as more evidence of the scale...
The paper presents the impact of trade-linked policies on the management of fisheries in West Africa. It raises issues
of national policies regarding fishery development but also the consequences of the ACP-EU cooperation and WTO
stakes.
Exploited throughout the marine and estuarian zones of West Africa, halieutic resources, in the...
Faidherbia albida is a widely used tree species in sub-Saharan Africa, promoted for use in parkland agroforestry systems based on reduced competition with crops during the rainy season from its reverse leafing phenology and positive effect on soil fertility. Increases in growth and yield have been reported for crops such...
Common bean (Phaseolus vulgaris L.) comes in a huge assortment of fresh and dried varieties, including snap beans, kidney beans, and pinto beans. Together, these and other market classes provide a third of the daily dietary protein in some cultures, particularly in Africa, Asia, and developing nations in the Americas....
Linkages between land use and its influence on the atmosphere have been a long-standing research area. For example, what is the impact of irrigated agriculture on downwind rainfall? Global-scale models show that moisture recycling is an important source of water for inland regions around the world, but they do not...
