Amid lengthening droughts in a changing climate, millions of herders in northern Kenya are watching their traditional grazing lands dry and harden. As in pastoralist regions from Mongolia to the Sahel, Kenyan herders are now guiding their cattle, camels, sheep or goats longer distances in search of pasturage. The competition for scarcer grassland and water has triggered conflicts and bloodshed among herding communities. But at the grass roots of northern Kenyan society, activists are combining local knowledge and peacebuilding skills to create new ways for rival groups to cooperatively adapt to the changes from a degrading climate.
