The most comprehensive and rigorous global study ever done on agricultural science and technology, published last year, gave clear recommendations about the kind of science which could contribute to reducing hunger and poverty. It advocated diverse agro-ecological farming which is already being practiced by small scale producers and warned that public policy goals had to radically shift to promoting these methods rather than risky and unproven genetic modification of crops. The International Assessment of Agricultural Science and Technology for Development (IAASTD) report was conducted by over 400 scientists from more than 80 countries and sponsored by 5 UN agencies and the World Bank. 60 Governments including the UK signed up to its findings.
