Inequality, drought and the deadly fight for precious grazing land in Kenya

Arrival of hundreds of poor tribesmen seeking grazing lands for their cattle has triggered outbreak of violence in Laikipia

Early one morning last week, Richard Constant drove across the 24,000-acre ranch that he part-owns on a high plateau in central Kenya to discover what remained of his home.

In March, Constant's friend and business associate Tristan Voorspuy, a British army officer turned safari operator, had been shot dead on his horse while inspecting the damage caused by armed herders who had driven tens of thousands of cattle on to the ranch.
