The increasing global human population is projected to reach 9.7 billion people by 2050. This population growth is currently linked to the trends of world-wide urbanization, growth of megacities and shifting dietary patterns. While humankind faces the daunting challenge of feeding and providing healthy lives for its teeming populations, urban agriculture holds promise for improving the quality of life in cities. Fortunately, policymakers and planners are accepting the need to support peri-urban farmers to increase the resilience of food systems while efficiently managing already strained natural resources. We argue that for urban agriculture to significantly increase food yields, it is crucial to adopt a One Health approach to agriculture and environmental stewardship. Here, we propose six nature-based and climate-smart approaches to accelerate the transition toward more sustainable food systems. These approaches include reducing the reliance on synthetic agricultural inputs, increasing biodiversity through producing locally adapted crops and livestock breeds, using probiotics and postbiotics, and adopting portable digital decision-support systems. Such radical approaches to transforming food production will require cross-sectoral stakeholder engagement at international, national, and community levels to protect biodiversity and the environment whilst ensuring sustainable and nutritious diets that are culturally acceptable, accessible, and affordable for all.
预计到2050年，全球人口将增至97亿。目前，这种人口增长与全球城市化趋势、特大城市的发展以及饮食模式的转变相关联。在人类面临为庞大人口提供食物和健康生活这一艰巨挑战之际，城市农业有望改善城市生活质量。幸运的是，政策制定者和规划者已认识到有必要支持城郊农民，以增强粮食系统的韧性，同时有效管理已然紧张的自然资源。我们认为，要让城市农业大幅提高粮食产量，采用“同一健康”方法进行农业和环境管理至关重要。在此，我们提出六种基于自然且气候智能型的方法，以加速向更可持续的粮食系统转型。这些方法包括减少对合成农业投入品的依赖、通过种植本地适应性作物和养殖本地适应性牲畜品种来增加生物多样性、使用益生菌和后生元，以及采用便携式数字决策支持系统。这种彻底改变粮食生产的方法将需要国际、国家和社区层面的跨部门利益相关者参与，以保护生物多样性和环境，同时确保所有人都能获得文化上可接受、可获取且负担得起的可持续营养饮食。
