In Kenya’s dry south-east there is a critical wildlife migration corridor called Kasigau, connecting Tsavo East and West National Parks. More than 2000 elephants share the land with local communities, who have traditionally survived by bush meat poaching and charcoal production. But in just 10 years a conservation non-profit called Wildlife Works has turned a dire situation around, by an effective use of carbon credits. The income provided has supported 120 rangers, 300 local jobs and thousands of scholarships for local students. Is it a model for other conservancies?
