Classrooms are key to teaching Namibia's nearly one million school-age children about conservation - yet Namibian teachers receive little training on environmental education. This new programme equips teachers with all-Namibian lessons to create a generation of environmental heroes, in every region of our vast country. Early morning, Etosha National Park. You can smell the cool, humid tang of night in the savannah still hanging on the air. The twittering of red-eyed bulbuls wakes a group of francolins, who add their chatter to the breaking day. Vilho Absalom, a Ministry of Environment and Tourism warden at the Namutoni Environmental Education Centre, is already hard at work. He is setting up an outdoor workshop, which he usually leads as part of a three-day course for schoolchildren visiting the park. Today, though, is a little different. Instead of children, fellow environmental educators arrived the previous night, travelling from government institutions and non-profit organisations in every corner of the country. These specialist educators hail from places that represent all the landscapes of Namibia: Namib Desert, Waterberg, Kavango and Zambezi, Succulent Karoo and the Atlantic Coast. They are here to work on a new kind of nature education for the nation.
