In the Sahelian rangelands biomass production is constrained by soil moisture in the drier (100-250 mm) parts and by soil nutrients in the wetter parts. Similarly, for a given Sahelian range, nutrient deficiency would be more prominent in good than in poor rainfall years. To test this hypothesis,...

Rural communities in sub-Saharan Africa commonly rely on shallow hand-dug wells and springs; consequently, shallow aquifers are an extremely important water source. Increased utilisation of shallow groundwater could help towards achieving multiple sustainable development goals (SDGs) by positivel...

El estado de Tabasco es sin duda la entidad más expuesta al fenómeno de las inundaciones en el país. Entre 2007 y 2011 su territorio ha sido impactado por estos fenómenos anualmente, acumulando daños y pérdidas por más de 57 mil millones de pesos. Entre septiembre y noviembre de 2011, el estado ...


1. Rainfall is the prime climatic factor underpinning the dynamics of African savanna ungulates,but no study has analysed its influence on the abundance of these ungulates at monthly to multiannual time scales. 2. We report relationships between rainfall and changes in age- and sex-structured ...

This article proposes strategy for agricultural technology development for semi-arid West Africa. The strategy evaluation consists of two aspects: a) a review of the successes in the region; and b) analysis with mathematical programming of the potential impacts and constraints to various new tech...

Agriculture is the mainstay of the country and also the major source of employment and income. About 85 percent of the population live in the rural areas and are primarily engaged in agriculture and related activities. Among the other agricultural sector, livestock production contributes about 30...

Not only does livestock make an important contribution to rural incomes and export earnings in the Sahel, it is also kept as insurance against weather risk. Fluctuations in livestock prices can therefore trigger food entitlement failures. Using monthly price data from Niger, we show that livestoc...
