Scientists and policy-makers globally are calling for alternative approaches to conventional intensification of agriculture that enhance ecosystem services provided by biodiversity. The evidence reviewed here suggests that alternative approaches can achieve high crop yields and profits, but the performance of other socioeconomic indicators (as well as long-term trends) is surprisingly poorly documented. Consequently, the implementation of conventional intensification and the discussion of alternative approaches are not based on quantitative evidence of their simultaneous ecological and socioeconomic impacts across the globe. To close this knowledge gap, we propose a participatory assessment framework. Given the impacts of conventional intensification on biodiversity loss and greenhouse gas emissions, such evidence is urgently needed to direct science-policy initiatives, such as the United Nations (UN) 2030 Agenda for Sustainable Development.
全球的科学家和政策制定者呼吁采取替代方法来加强农业,以提高生物多样性提供的生态系统服务。本文回顾了相关证据,表明替代方法可以实现高作物产量和利润,但其他社会经济指标(以及长期趋势)的表现却鲜少被记录。因此,传统集约化的实施和替代方法的讨论并非基于其对全球生态和社会经济影响的定量证据。为了弥补这一知识差距,我们提出了一个参与式评估框架。鉴于传统集约化对生物多样性丧失和温室气体排放的影响,迫切需要这种证据来指导科学政策倡议,如联合国(UN)2030 年可持续发展议程。
