At the end of a visit to West Africa, Josette Sheeran was reported as saying that time was running out to build resilience among the millions of rural Africans who often have to go hungry.
"I have seen in West Africa what havoc could be caused by the triple threat of climate change, rising food prices and population growth," she said.
"But I have also seen that there are solutions to help people adapt before it is too late. We must help people to protect themselves and their families. It’s a large order, but with the help of the international community we can do it – we must do it."
