Higher food demands and scarce resources are putting pressure on agricultural systems. How can productivity be increased within environmental limits, what is the role science and technology in sustainable agriculture, and what can be done to further develop new crop management systems?

This Spotlight presents an in-depth analysis including opinions, facts and figures, key reports and useful links. Fernando R. Funes-Monzote, agroecologist, researcher, consultant and farmer based in Cuba; David J. Spielman, senior research fellow at the International Food Policy Research Institute; and Norman Uphoff, professor at Cornell University and senior advisor to the Cornell SRI-Rice Center; offer their views on the debate.
