title: Malthus foiled again and again.
abstract: Throughout history, increasing population has driven the need to increase agricultural efficiency, so averting successive 'malthusian' disasters. In the twentieth century, the application of scientific knowledge to agriculture yielded tremendous dividends, enabling cereal yields to increase threefold since 1950. But with the world's population projected to reach nine billion by the middle of this century, new ways must be found to increase yields while preserving natural habitats and biodiversity.
