(BBC) An estimated one million people across Africa have been hit by prolonged rains which have destroyed crops, burst dams and left dozens dead, officials say.
Parts of Ghana have been declared a disaster zone, while on the other side of the continent, many thousands are now homeless in Ethiopia and Uganda.
The UN said the floods could lead to locust infestations and outbreaks of water-borne diseases such as cholera.
The flooding and torrential rain have brought chaos to at least 14 countries.
UN Office for the Coordination of Humanitarian Affairs spokeswoman Elisabeth Byrs said 500,000 people had been affected in West Africa and a further 500,000 in Sudan, and the numbers were rising.
