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.
当前的食物生产和消费趋势与《生物多样性公约》2050 年与自然和谐相处的愿景不一致。在这里,我们研究了 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食物系统的变革性转变。我们对四个科学政策论坛中提出的行动进行了分析,结果表明,补贴改革、评估、减少食物浪费、可持续性标准、生命周期评估、可持续饮食、将生物多样性纳入主流以及加强治理可以支持更可持续的食物生产和消费。通过考虑在秘鲁和英国实施这些行动的障碍和机会,我们得出了 2020 年后生物多样性框架的潜在目标和指标。为了支持转型,需要有真正的政治承诺、问责制和合规性,以及更广泛的有利条件和来自不同利益相关者的行动,才能使食物系统走上可持续发展的道路。
