On one side there are tools to mobilise protest, on the other are tools of state control and surveillance.

Map Kibera

Ten years ago Digital Planet reported on the Map Kibera project, which was just an idea to provide information to OpenStreetMap about the Nairobi slum. This quickly turned into the Map Kibera Organisation which makes sure that Kibera is connected and is focussed on improving people’s lives in the slum. Digital Planet has been back to Kibera to see how the project has changed.

First ever plant selfie

Hannah Fisher reports on a plant called Pete which could revolutionise field conservation by powering a camera to take selfies as he grows. London Zoo scientists have laid the groundwork for the world’s first plant selfie – a pioneering scientific trial in the Zoo’s Rainforest Life exhibit which will try out how microbial fuel cells power a plant to take its own picture. This they hope will lead to using plants to power camera traps and sensors in the wild allowing conservationists to monitor habitats remotely.
