我们在二十一世纪确保粮食安全所面临的挑战与其他全球问题之间存在着内在的联系，其中最引人注目的是气候变化、人口增长以及可持续管理世界快速增长的能源和水需求的需要。我们在减少全球贫困和实现千年发展目标方面取得的进展在很大程度上取决于如何协调一致地应对这些长期挑战。一个关键问题是我们能否公平、健康和可持续地养活未来 90 亿人。科学技术可以通过提供实用的解决方案做出重大贡献。要确保这一贡献，就需要高度重视研究并促进现有技术和新兴技术在现实世界的部署。简而言之，我们需要一场新的“绿色革命”。重点关注领域包括：作物改良；更明智地使用水和肥料；新农药及其有效管理以避免耐药性问题；引入新颖的非化学作物保护方法；减少收获后损失；以及更可持续的畜牧业和海洋生产。需要来自许多学科的技术和工艺，从生物技术和工程学到纳米技术等新领域。
There is an intrinsic link between the challenge we face to ensure food security through the twenty-first century and other global issues, most notably climate change, population growth and the need to sustainably manage the world's rapidly growing demand for energy and water. Our progress in reducing global poverty and achieving the Millennium Development Goals will be determined to a great extent by how coherently these long-term challenges are tackled. A key question is whether we can feed a future nine billion people equitably, healthily and sustainably. Science and technology can make a major contribution, by providing practical solutions. Securing this contribution requires that high priority be attached both to research and to facilitating the real world deployment of existing and emergent technologies. Put simply, we need a new, ‘greener revolution’. Important areas for focus include: crop improvement; smarter use of water and fertilizers; new pesticides and their effective management to avoid resistance problems; introduction of novel non-chemical approaches to crop protection; reduction of post-harvest losses; and more sustainable livestock and marine production. Techniques and technologies from many disciplines, ranging from biotechnology and engineering to newer fields such as nanotechnology, will be needed.
