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. 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. 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.
绿色革命自 20 世纪 60 年代以来被认为缓解了饥荒、减轻了贫困并推动了总经济增长。在亚洲,高投入技术包确保了水稻产量增加两倍,而种质改良带来的效益超过 430 亿美元。在这里,我们揭示了在 1918 年至 2018 年期间(跨越 23 个不同的亚太地缘政治实体),自然因素对非水稻作物生产力增长的平行贡献的规模和宏观经济相关性。我们通过实证证明了生物防治如何解决多种农业商品中的入侵害虫威胁,确保每年(农场)获得 146 亿至 195 亿美元的收益。科学指导的对 43 种外来无脊椎害虫的生物防治使香蕉、面包果、木薯和椰子等关键粮食、饲料和纤维作物的 73%-100%的产量损失得到恢复。生物防治因此促进了农村的增长和繁荣,即使在边缘地区、资源匮乏的非水稻环境中也是如此。通过将农业生态创新与投入密集型措施置于同等地位,我们的工作为未来减轻入侵物种、恢复生态弹性和可持续提高全球农业食品系统产量的努力提供了经验。
