为迅速增长的全球人口提供可持续的粮食生产是本世纪的一项重大挑战。为了满足粮食生产的需求，每年将需要2.7-4.9 Mha的额外土地用于农业。然而，三分之一的可耕地已经受到污染;因此，在现代农业中，污染土地的利用将成为一个重要问题。然而，使用这些土地带来了更多的挑战，适当的农业技术干预对于确保相关生产系统的安全和可持续性至关重要。还有其他一些问题需要考虑，例如成本效益分析、污染物可能进入植物产品、此类产品的认证和销售，以便大规模开发受污染的土地。本文讨论了污染土地作物生产的可持续性挑战，并简要概述了利用污染土地进行可持续农业推广的可行战略。
Sustainable food production for a rapidly growing global population is a major challenge of this century. In order to meet the demand for food production, an additional land area of 2.7-4.9 Mha year(-1) will be required for agriculture. However, one-third of arable lands are already contaminated; therefore, the use of polluted lands will have to feature highly in modern agriculture. The use of such lands comes, however, with additional challenges, and suitable agrotechnological interventions are essential for ensuring the safety and sustainability of relevant production system. There are also other issues to consider, such as cost-benefit analysis, the possible entry of pollutants into the phytoproducts, certification and marketing of such products, in order to achieve the large-scale exploitation of polluted lands. The present article addresses the sustainability challenges of crop production from polluted lands and briefly outlines the plausible strategies for using polluted lands for sustainable agricultural extensification.
