“…A vivid example is the ''paradox'' which is an observed runoff increase in some of the basin's Sahelian catchments such as in Nakanbe (Burkina Faso), Sirba (Niger) and Mekrou (Benin) despite a decrease in rainfall (Mahe et al 2005;Descroix et al 2009). This was attributed to soil crusting and land degradation as a result of unsustainable land use in the basin (Amogu et al 2010).…”

Hydro-climatic changes in the Niger basin and consistency of local perceptions

et al. 2014

Since the 1970s, the Niger basin has been characterized by hydro-climatic changes which have significant impacts on local populations. These changes are not well documented as a result of a decreasing observation network for hydro-climatic data. Indigenous peoples' knowledge has increasingly been considered an important component in addressing these data gaps. We evaluated the consistency of indigenous perceptions and adaptive responses with rainfall and river discharge observations in the Niger basin. Socioeconomic data were collected from 239 households in 30 communities across two settlements in the Niger basin. Data on historical rainfall and river discharge from 1950 to 2010 were analyzed and the consistency with local perceptions was assessed. Generally, there was a high agreement between observations and perceptions, but impacts of climate change in the communities were dependent on social and environmental factors that can introduce differences in perception despite identical observations. Indigenous perceptions gave good indication of the most vulnerable sectors as well as communities who also displayed the greatest willingness to combat climate change. These results suggest that integration of indigenous perceptions into climate change science, especially in data scarce regions, is highly valuable.

Rodriguez-Iturbe (2000), Peterson et al (2000), Woods (2005) and Anderson et al (2005) provide perspective on hydrological variability and other background information highly relevant to the issue of scales of climate variability and land cover change impact on flooding and low flows.…”

“…There appears to be a trend toward a decrease in precipitation since 1970 (L'Hôte et al 2002). At the same time, as a consequence of land-use change, the runoff coefficient has increased from 1.5 to 3.0% in the northern part of the Nakambé (White Volta) Basin, resulting in increased discharge despite reduced rainfall (Mahé et al 2005). Floods are very violent and cause severe and recurrent damage to hydraulic infrastructure, particularly dikes and bridges.…”

Options for water storage and rainwater harvesting to improve health and resilience against climate change in Africa

et al. 2012

West and East Africa experience high variability of rainfall that is expected to increase with climate change. This results in fluctuations in water availability for food production and other socioeconomic activities. Water harvesting and storage can mitigate the adverse effects of rainfall variability. But past studies have shown that when investments in water storage are not guided by environmental health considerations, the increased availability of open water surface may increase the transmission of waterrelated diseases. This is demonstrated for schistosomiasis associated with small reservoirs in Burkina Faso, and for malaria in Ethiopia around large dams, small dams, and water harvesting ponds. The concern is that the rush to develop water harvesting and storage for climate change adaptation may increase the risk for already vulnerable people, in some cases more than canceling out the benefits of greater water availability. Taking health issues into account in a participatory approach to planning, design, and management of rainwater harvesting and water storage, as well as considering the full range of water storage options would enable better opportunities for enhancing resilience against climate change in vulnerable populations in sub-Saharan Africa.
