Mul, Marloes L.Williams, Timothy O.Cofie, Olufunke O.[Paysage scientifique, politique et financier de l’Agriculture Intelligente face au Climat (AIC) en Afrique de l’Ouest : le secteur des ressources en eau. In French]Paysage scientifique, politique et financier de l’Agriculture Intelligente face au Climat (AIC) en Afrique de l’Ouest : le secteur des ressources en eau. In French

Understanding long-term climatic variability is basic to wise management and conservation of biodiversity. We analysed temporal variations in the local rainfall, temperature, Normalized Difference Vegetation Index and the hemispheric El Niño-Southern Oscillation (ENSO), using the Southern Oscilla...


Ogutu, Joseph O.Piepho, Hans-PeterDublin, H.T.Bhola, N.Reid, S.[El Niño-Southern Oscillation, rainfall, temperature and normalized difference vegetation index fluctuations in the Mara-Serengeti ecosystem]El Niño-Southern Oscillation, rainfall, temperature and normalized difference vegetation index fluctuations in the Mara-Serengeti ecosystem

The vast majority of farmers in sub-Saharan Africa depend on rainfed agriculture for food production and livelihood. Various factors including but not limited to rainfall variability, land degradation, and low soil fertility constrain agricultural productivity in the region. The objectives of thi...

The Ganges River Basin may have a major pending water crisis. Although the basin has abundant surface water and groundwater resources, the seasonal monsoon causes a mismatch between supply and demand as well as flooding. Water availability and flood potential is high during the 3–4 months of the ...

As satellite technology develops, satellite rainfall estimates are likely to become ever more important in the world of food security. It is therefore vital to be able to identify the uncertainty of such estimates and for end users to be able to use this information in a meaningful way. This pape...

The overall aim of this study was to explore what the development community can do, or facilitate, to significantly improve livelihoods in semi-arid systems.The authors based their analysis on two case-study sites in the communal lands of southern Zimbabwe. The main tool was a detailed livelihood...

Due to increased population pressure and limited availability of fertile land, farmers on desert fringes increasingly rely on marginal land for agricultural production, which they have learned to rehabilitate with different technologies for soils and water conservation. One such method is the ind...

AndréGerard, Bruno G.[Effect of planting technique and amendment type on pearl millet yield, nutrient uptake, and water use on degraded land in Niger]Effect of planting technique and amendment type on pearl millet yield, nutrient uptake, and water use on degraded land in Niger

While the berlett-Lewis model has been widely used for modelling rainfall processes at a fixed point in space over time, there are observed features, such as longer-scale dependence, which are not well fitted by the model. In this paper is a study of an extension where the authors put an extra la...

Climatic condition, geology, and geochemical processes in an area play a major role on groundwater quality. Impact of these on the fluoride content of groundwater was studied in three regions-part of Nalgonda district in Telangana, Pambar River basin, and Vaniyar River basin in Tamil Nadu, southe...
