The Green Revolution is credited with alleviating famine, mitigating poverty and driving aggregate economic growth since the 1960s. In Asia, high-input technology packages secured a tripling of rice output, with germplasm improvements providing benefits beyond US$4.3 billion yr–1. Here, we unveil the magnitude and macro-economic relevance of parallel nature-based contributions to productivity growth in non-rice crops over the period 1918–2018 (across 23 different Asia–Pacific geopolitical entities). We empirically demonstrate how biological control resolved invasive pest threats in multiple agricultural commodities, ensuring annually accruing (on-farm) benefits of US$14.6–19.5 billion yr–1. Scientifically guided biological control of 43 exotic invertebrate pests permitted 73–100% yield-loss recovery in critical food, feed and fibre crops including banana, breadfruit, cassava and coconut. Biological control thereby promoted rural growth and prosperity even in marginal, poorly endowed, non-rice environments. By placing agro-ecological innovations on equal footing with input-intensive measures, our work provides lessons for future efforts to mitigate invasive species, restore ecological resilience and sustainably raise output of global agrifood systems.

生态害虫控制加强了亚太经济体的农业增长。

自1960年代以来,绿色革命以减轻饥荒,减轻贫困和推动总体经济增长而著称。在亚洲,高投入的技术配套确保了稻米产量的三倍,而种质改良带来的收益超过43亿美元– 1年。在这里,我们揭示了1918-2018年间(横跨23个不同的亚太地缘政治实体)基于自然的平行贡献对非水稻作物生产力增长的程度和宏观经济相关性。我们从经验上证明生物控制如何解决多种农产品中的入侵性虫害威胁,确保每年产生(农业)收益(146-19.5亿美元-1)。以科学指导的方式对43种外来无脊椎动物有害生物进行生物控制,使关键食品,饲料和纤维作物(包括香蕉,面包果,木薯和椰子)的产量损失恢复了73-100%。因此,即使在边际,资源匮乏的非稻米环境中,生物控制也促进了农村的增长和繁荣。通过将农业生态创新与投入密集型措施放在平等的基础上,我们的工作为减轻入侵物种,恢复生态适应力和可持续提高全球农业食品系统的产量的未来努力提供了经验教训。
