摘要

由于当前土地利用对环境的负面影响,以及土地在碳、生物多样性和粮食安全方面的重要作用,土地利用改革迫在眉睫。植树以固碳和保护土地以增加生物多样性的政策目标需要土地重新分配,这导致不可避免的权衡。在这里,我们通过在覆盖英国的500米网格上计算这三个目标的指标,评估了农村土地的三个目标:农业/林业生产、碳封存和生物多样性之间的权衡。我们使用多目标优化,使我们能够探索可能的土地转换的全部选择空间,并确定需要有限权衡的土地分配。我们的研究结果表明,对于任何目标组合而言,英国目前的土地利用都远未达到最佳状态。我们确定了可以在不影响整体农业生产的情况下大幅改善碳封存和生物多样性的地点,前提是仔细定位转换。

Strategic land reallocation enhances carbon sequestration and biodiversity protection without compromising agricultural productivity in Great Britain.

Due to the negative environmental consequences of current land-use, and land's important role regarding carbon, biodiversity and food security, there is an urgent interest in reforming land-use. Policy objectives for tree planting to sequester carbon and the protection of land to increase biodiversity require land reallocation, which leads to inevitable trade-offs. Here, we evaluate the trade-offs between three objectives for rural land: agricultural/forestry production, carbon sequestration and biodiversity, by calculating metrics for these three objectives on a 500 m grid covering Great Britain. We use a multi-objective optimisation that allows us to explore the full option space of possible land conversions and identify the land allocations that entail limited trade-offs. Our results show that current land-use in Great Britain is far from optimal for any combination of objectives. We identify the locations where carbon sequestration and biodiversity can be substantially improved without compromising overall agricultural production, provided conversions are located carefully.
