改变粮食系统的行动是解决生物多样性丧失问题的关键。目前的粮食生产和消费趋势与《生物多样性公约》提出的2050年与自然和谐相处的愿景不一致。在这里,我们研究2020年后的生物多样性框架如何以及在什么条件下能够支持粮食系统的变革性变化。我们对四个科学政策论坛提出的行动的分析表明,补贴改革、估值、减少食物浪费、可持续性标准、生命周期评估、可持续饮食、生物多样性主流化和加强治理可以支持更可持续的粮食生产和消费。通过考虑在秘鲁和联合王国实施这些行动的障碍和机会,我们得出2020年后生物多样性框架的潜在目标和指标。对于支持转型的目标,需要真正的政治承诺、问责和遵守,以及更广泛的有利条件和不同主体采取的行动,以使粮食系统走上可持续的道路。
Actions to transform food systems are key to addressing biodiversity loss. Current food production and consumption trends are inconsistent with the Convention on Biological Diversity’s 2050 vision of living in harmony with nature. Here, we examine how, and under what conditions, the post-2020 biodiversity framework can support transformative change in food systems. Our analysis of actions proposed in four science-policy fora reveals that subsidy reform, valuation, food waste reduction, sustainability standards, life cycle assessments, sustainable diets, mainstreaming biodiversity, and strengthening governance can support more sustainable food production and consumption. By considering barriers and opportunities of implementing these actions in Peru and the United Kingdom, we derive potential targets and indicators for the post-2020 biodiversity framework. For targets to support transformation, genuine political commitment, accountability and compliance, and wider enabling conditions and actions by diverse agents are needed to shift food systems onto a sustainable path.
