Society faces the double challenge of increasing biomass production to meet the future demands for food, materials and bioenergy, while addressing negative impacts of current (and future) land use. In the discourse, land use change (LUC) has often been considered as negative, referring to impacts of deforestation and expansion of biomass plantations. However, strategic establishment of suitable perennial production systems in agricultural landscapes can mitigate environmental impacts of current crop production, while providing biomass for the bioeconomy. Here, we explore the potential for such “beneficial LUC” in EU28. First, we map and quantify the degree of accumulated soil organic carbon losses, soil loss by wind and water erosion, nitrogen emissions to water, and recurring floods, in ∼81.000 individual landscapes in EU28. We then estimate the effectiveness in mitigating these impacts through establishment of perennial plants, in each landscape. The results indicate that there is a substantial potential for effective impact mitigation. Depending on criteria selection, 10–46% of the land used for annual crop production in EU28 is located in landscapes that could be considered priority areas for beneficial LUC. These areas are scattered all over Europe, but there are notable “hot-spots” where priority areas are concentrated, e.g., large parts of Denmark, western UK, The Po valley in Italy, and the Danube basin. While some policy developments support beneficial LUC, implementation could benefit from attempts to realize synergies between different Sustainable Development Goals, e.g., “Zero hunger”, “Clean water and sanitation”, “Affordable and Clean Energy”, “Climate Action”, and “Life on Land”.

社会面临着双重挑战，即增加生物量产量以满足未来对食物，材料和生物能源的需求，同时解决当前（以及未来）土地使用的负面影响。在本文中，土地利用变化（LUC）通常被认为是负面的，指的是森林砍伐和生物质人工林扩张的影响。但是，战略性地在农业景观中建立合适的多年生生产系统可以减轻当前作物生产对环境的影响，同时为生物经济提供生物量。在这里，我们探讨了EU28中这种“有益的LUC”的潜力。首先，我们绘制并量化了EU28中约81.000个个体景观中累积的土壤有机碳损失，因风蚀和水蚀造成的土壤流失，向水中排放的氮以及反复发生的洪水的程度。然后，我们通过在每个景观中建立多年生植物来评估减轻这些影响的有效性。结果表明，有效缓解影响的潜力很大。根据选择的标准，EU28中用于年度作物生产的土地中有10–46％的土地被认为是有利于土地利用的土地利用的优先区域。这些地区散布在整个欧洲，但重点地区集中在一些明显的“热点”，例如丹麦，英国西部，意大利的波河谷和多瑙河盆地的大部分地区。尽管一些政策发展支持有益的土地利用价值，但实施可能会受益于实现不同可持续发展目标（例如“零饥饿”，“清洁水和卫生设施”，“负担得起的清洁能源”，
