Kate Adie presents dispatches from: Stephanie Hegarty in Nigeria on how the plight of former girl captives of the Boko Haram Islamist insurgents is being addressed when many return to their home communities only to ostracised and disowned; Edmund Bower on the murky political techniques employed in Egypt against some young activists as the presidential election approaches; Vincent Ni in Japan on a remarkable North Korean "minder" at a school educating children of Korean descent; Lizzie Porter on the savage depopulation affecting highland villages in Bosnia-Herzegovina - and those who are determined to stay; and Richard Hamilton, who visits Salt Spring Island off the coast of British Columbia to learn about a one-time Scottish welder who wrought a 1970s revolution in mental health that has survived the hippy era.
