The Earth's population is expected to exceed 9 billion by 2050, posing significant challenges in meeting human needs while minimally affecting the environment. To support this population, we will need secure and safe sources of food, energy, and water. The nexus of food, energy, and water is one of the most complex, yet critical, issues that face society. There is no more land to exploit, and the supply of fresh water in some areas of the world limits the use of land for food. All solutions must also deal with the overlay of global climate change. Meeting current and future populations needs will require security in food, energy, and water supplies. A nexus approach is needed to improve food, energy, and water security integrating the management of the limited resources while transitioning to a more "green" economy, which provides adequate food, energy, and water for the expanding human population.
预计到2050年，地球人口将超过90亿，这在满足人类需求同时将对环境的影响降至最低方面带来了重大挑战。为了养活这么多人口，我们将需要安全可靠的食物、能源和水源。粮食、能源和水的关系是社会面临的最复杂但又至关重要的问题之一。已没有更多土地可供开发，世界上一些地区的淡水供应限制了用于粮食生产的土地使用。所有解决方案还必须应对全球气候变化的叠加影响。满足当前和未来人口的需求将需要粮食、能源和水供应的安全保障。需要一种系统方法来改善粮食、能源和水安全，整合有限资源的管理，同时向更“绿色”的经济转型，为不断增长的人口提供充足的食物、能源和水。
