The southern nations of West Africa are beginning to experience the second and shorter of their rainy seasons, whilst those countries further north are seeing the end of theirs. For many the happiness of seeing these rains is mixed with anxieties from memories past and current realities. Exceptionally heavy seasonal rainfall in 2007, 2009, 2013 and 2017 saw several major rivers break their banks, causing destruction of houses, bridges, roads and crops, wrecking livelihoods and displacing vast swathes of the population.
In recent weeks, floods have severely hit parts of Burkina Faso, Ghana, Niger and Nigeria, leading to the death of at least 107 people and affecting hundreds of thousands. In Senegal, a state of emergency has been declared following heavy rainfalls and the death of four citizens, while in Chad nearly 200,000 people have been affected. Yet again, the urgent need for immediate action to mitigate and alleviate the effects of climate change has been exposed.
