在“完美风暴”情景下实现粮食安全是社会面临的一项重大挑战。气候变化和不断扩大的全球人口共同作用，使全球粮食安全变得更加复杂和苛刻。由于实现粮食安全和消除饥饿的千年发展目标影响到其他千年发展目标的实现，我们必须提供相辅相成而不是相互对立的解决办法。有人提议将可持续集约化农业作为解决饥饿问题的一种方式，同时也尽量减少对环境的进一步影响。然而，提高生产力和产量的愿望历来导致环境退化、生物多样性减少和生态系统服务减少，对穷人的影响最大。本文提出，ES框架与政策响应框架相结合，例如驱动-压力-状态-影响-响应(DPSIR)，可以使粮食安全与健康的生态系统一起提供，健康的生态系统为人类提供许多其他有价值的服务。农业生态系统往往被认为与其他自然生态系统是分开的，对服务进出农业生态系统并流向周围生态系统的方式重视不够。我们重点介绍了最近在一个大型多学科项目(ASSET)中进行的研究，并使用马拉维Zomba地区的一个案例研究说明了粮食安全的ES方法。
Achieving food security in a ‘perfect storm’ scenario is a grand challenge for society. Climate change and an expanding global population act in concert to make global food security even more complex and demanding. As achieving food security and the millennium development goal (MDG) to eradicate hunger influences the attainment of other MDGs, it is imperative that we offer solutions which are complementary and do not oppose one another. Sustainable intensification of agriculture has been proposed as a way to address hunger while also minimizing further environmental impact. However, the desire to raise productivity and yields has historically led to a degraded environment, reduced biodiversity and a reduction in ecosystem services (ES), with the greatest impacts affecting the poor. This paper proposes that the ES framework coupled with a policy response framework, for example Driver-Pressure-State-Impact-Response (DPSIR), can allow food security to be delivered alongside healthy ecosystems, which provide many other valuable services to humankind. Too often, agro-ecosystems have been considered as separate from other natural ecosystems and insufficient attention has been paid to the way in which services can flow to and from the agro-ecosystem to surrounding ecosystems. Highlighting recent research in a large multi-disciplinary project (ASSETS), we illustrate the ES approach to food security using a case study from the Zomba district of Malawi.
