Across East Africa, millions of people are facing starvation as the worst drought in living memory enters its third year.

Four rainy seasons have failed to materialise - it’s feared a fifth, due any time now, will also not arrive. But for people in Kenya’s Turkana region, drought isn’t the only natural disaster they face. Just a few kilometres away from drought-ridden areas, Lake Turkana has expanded, causing floods that have destroyed homes and claimed lives.

While man-made climate change is said to be a contributing factor, deforestation in the highlands and overgrazing have made a bad situation worse.

Newsnight's Joe Inwood travelled to northern Kenya to find out what is going on, and what role global warming has played in the fate of the people of Turkana.
