Gamba Manyatta village is empty now, weeds already roping around the few skeletal hut frames still standing. The people who were evicted took as much of their building materials as they could carry to start again and the land where their homes stood is now ploughed up. The eviction of the villagers to make way for a sugar cane plantation is part of a wider land grab going on in Kenya's Tana Delta that is not only pushing people off plots they have farmed for generations, stealing their water resources and raising tribal tensions that many fear will escalate into war, but also destroying a unique wetland habitat that is home to hundreds of rare and spectacular birds.
