Tristram Stuart is the winner of the international environmental award, The Sophie Prize 2011, for his fight against food waste. Following the critical success of Tristram’s first book, The Bloodless Revolution (2006), ‘a genuinely revelatory contribution to the history of human ideas’, Tristram has become a renowned campaigner, working in several countries to help improve the environmental and social impact of food production. His latest international prize-winning book, Waste: Uncovering the Global Food Scandal (Penguin, 2009), revealed that Western countries waste up to half of their food, and that tackling this problem is one of the simplest ways of reducing pressure on the environment and on global food supplies. Tristram set up the Feeding the 5000 (www.feeding5k.org), the flagship event of a global food waste campaign where 5000 members of the public are given a free lunch using only ingredients that otherwise would have been wasted. Held twice in Trafalgar Square (2009 and 2011), the Feeding the 5000 team have now launched replica events and campaigns internationally, and has now been commissioned to work globally in partnership with the European Commission and the United Nations Environment Program. Tristram continues to work with a range of NGOs, governments, and private enterprises internationally to tackle the global food waste scandal.
