Colombia: Climate-friendly palm oil production - Palm oil is processed for use in cosmetics, food and bio-fuel. But it remains controversial because rainforest is often destroyed to make way for palm plantations, thus eliminating an important carbon sink. A company in Colombia is rethinking the process by growing its palm oil plantations on disused fields. The methane produced during production is captured and used to generate electricity. Electromobility in Uganda - Every day, hundreds of thousands of vehicles choke the streets of the Ugandan capital Kampala. The air is thick with fumes. To help promote cleaner technology, a team at the University of Makerere has developed an electric car - the green Kiira. Designing it was a huge challenge for the students, as Uganda is not a carmaking nation. But now the African country wants to show that it too can produce cutting-edge technology. Organic Shrimp Farming in Thailand - Demand for organic foods is increasing around the world. In 2010, global sales of organic foods were thought to total some 44.5 billion euros. Organic cocktail shrimps are in great demand. They wind up in supermarkets in the US and Europe -- the world's biggest markets for organic foods. Kritsada Hongrath, from the province of Chanthaburi, is one of Thailand's few organic farmers. With over 140 ponds, his operation is one of the biggest in Thailand. But few seem willing to follow his lead. In spite of the demand for organic products, the cultivation methods prove too expensive for many Thai shrimp farmers. In Thailand, sustainable farming is more the exception than the rule and the use of antibiotics is an open secret.
