Farmlands are currently among the dominant uses of the land. When managed under low-input farming systems, farmlands are associated with diverse cultural and natural heritages around the world. Known in Europe as high nature value (HNV) farmlands, these agricultural landscapes and their associated farming systems evolved as tightly coupled socioecological systems, and are essential to biodiversity conservation and the delivery of ecosystem services to society. However, HNV farmlands are vulnerable to socioeconomic changes that lead to either agricultural intensification or land abandonment. We present a range of plausible future scenarios for HNV farmlands, and discuss the related management options and expected socioecological outcomes for each scenario. We then provide recommendations for policy, practice, and research on how to best ensure the socioecological viability of HNV farming systems in the future.

回到未来：重新思考高自然价值农田背后的社会生态系统

目前，农田是土地的主要用途之一。在低投入农业系统下进行管理时，农田与世界各地的各种文化和自然遗产有关。在欧洲被称为高自然价值 (HNV) 农田，这些农业景观及其相关的农业系统演变为紧密耦合的社会生态系统，对于生物多样性保护和向社会提供生态系统服务至关重要。然而，HNV 农田容易受到导致农业集约化或土地遗弃的社会经济变化的影响。我们为 HNV 农田提出了一系列可能的未来情景，并讨论了每个情景的相关管理方案和预期的社会生态结果。然后，我们为政策、实践、
