In the Sahel, sandy soils are widespread and support not only most of pearl millet production, the major staple crop in the region, but also forage production for livestock. Parent sediments of these soils have an aeolian origin and hence are prone to wind erosion. However, the clay content, albe...

Wind and water erosion of non cultivated sandy soils in the Sahel: a case study in northern Burkina Faso, Africa
Reviving the Ganges Water Machine (GWM), coined 40 years ago, is the most opportune solution for mitigating the impacts of recurrent droughts and floods in the Ganges River Basin in South Asia. GWM create subsurface storage (SSS) by pumping more groundwater from the aquifers before the monsoon fo...

Increasing frequency of drought events coupled uncertainty imparted by climate change pose grave threat to agriculture and thereby overall food security. This is especially true in South Asian region where world’s largest concentration of people depends on agriculture for their livelihood. Indic...

This study examines farmers perceptions of short- and long-term variability in climate, their ability to discern trends in climate and how the perceived trends converge with actual weather observations in five districts of Eastern Province in Kenya where the climate is semi-arid with high intra-...

Climate variability and change: Farmer perceptions and understanding of intra-seasonal variability in rainfall and associated risk in semi-arid Kenya
Farming in the semi-arid tropics, where climatic conditions are marginal and highly variable, is a risky enterprise. The main source of this risk is the variability in rainfall that occurs at many different timescales, ranging from seasons to years to decades and beyond. Farmers operating under t...

Groundwater is an important resource for multiple uses in South Africa. However, setting limits to its sustainable abstraction while assuring basic human needs is a must. Due to prevalent data scarcity related to groundwater replenishment, which is the traditional basis for estimating groundwater...

In the highly risky environment of the Sahel, livestock play an important role as a form of insurance against weather risk in addition to their important contributions to rural incomes, urban meat supply and export earnings. Most Sahelian farmers and pastoralists pursue production strategies that...
Trends in rainfall series were investigated at 16 stations in Ghana over the period 1960-2005. Time series were first de-correlated using an effective pre-whitening methodology and then submitted to the resampling-based Mann-Kendall test. Field significances were assessed using the regional avera...
