摘要

水稻是一种重要的主食,但其镉含量的积累引发了人们对食品安全和生态系统安全的广泛关注。在这里,我们在中国湘江流域进行了为期七年的系统性田间试验,建立了综合治理框架(IGF),以确保水稻安全。综合治理框架针对地理分区和污染分级,包括有针对性的土壤处理、作物管理策略和利益相关者参与。土壤和作物的质量都得到了改善,土壤中的镉含量减少了 36%,大米颗粒中的镉含量减少了 57-78%。这一框架不仅应对了多重挑战,还通过促进科学、政策和当地社区参与之间的全面协同作用,支持了可持续发展目标(SDGs 2、3、6、9)。我们的研究结果为镉污染地区的水稻安全生产提供了经验指导,并在全球范围内提供了可靠的科学决策支持。

Achieving synergistic benefits through integrated governance of cultivated cadmium contamination via multistakeholder collaboration

Rice serves as a vital staple food, but its accumulation of cadmium (Cd) has sparked widespread concerns regarding food safety and ecosystem security. Here, we conducted a seven-year systematic field experiment in the Xiangjiang River Basin of China, where an integrated governance framework (IGF) was established to ensure rice safety. The IGF, tailored to geographical zoning and pollution gradation, includes targeted soil treatments, crop management strategies, and stakeholder engagement. The quality of both the soil and the crop was improved, with a reduction in soil Cd availability of 36%, and a decrease in Cd in rice grain of 57-78%. This framework not only addresses multiple challenges but also supports sustainable development goals (SDGs 2, 3, 6, 9) by fostering comprehensive synergies among science, policy, and local community participation. Our findings provide empirical guidance for safe rice production in Cd-contaminated areas and provide solid scientific-driven decision support globally.
