As water falls short, conflict between herders and farmers sharpens

It's a hot, windy afternoon in Kiboya village. Dusty leaves swirl around William Ekidor, his wife Martha and their two sons as they sit under an acacia tree by the Kajunge dam, queuing with their animals for water.

Ekidor and his family, pastoralists who herd 140 cattle, sheep and goats for a living, have travelled over 10 kilometres (6 miles) to the dam, the only remaining water source in the area, and a major source of conflict in the lowland basin of Laikipia County.
