Low-intensity agriculture is important for the conservation of many European habitats and species. However, biodiverse farmlands-also referred to as high nature value (HNV) farmlands-are threatened by years of agricultural intensification and land abandonment. Considering the ongoing changes in land-cover-evident throughout Europe-it is important to assess how land transformation is affecting HNV farmlands. Here, we evaluate land-cover changes within HNV farmlands during 2006-2018. We find that HNV farmlands inside Natura 2000 sites are less likely than those outside to be converted to artificial surfaces and more likely to maintain mosaic farming. However, land transformation patterns vary between member states, suggesting that different processes are driving the land-cover changes within each state. We recommend that member states support HNV farmers by making a more effective use of the Common Agricultural Policy (CAP) and that the EU prioritizes the protection of HNV farmlands during its next CAP reform post-2020.
低强度农业对于许多欧洲栖息地和物种的保护至关重要。然而,生物多样性丰富的农田——也被称为高自然价值(HNV)农田——正受到多年农业集约化和土地撂荒的威胁。鉴于整个欧洲土地覆盖的持续变化显而易见,评估土地转变如何影响高自然价值农田非常重要。在此,我们评估了2006年至2018年期间高自然价值农田内的土地覆盖变化。我们发现,“自然2000”保护区内的高自然价值农田比保护区外的农田更不容易转变为人工地表,且更有可能维持镶嵌式农业。然而,各成员国之间的土地转变模式有所不同,这表明不同的过程在推动每个国家内部的土地覆盖变化。我们建议各成员国通过更有效地利用共同农业政策(CAP)来支持高自然价值农田的农民,并且欧盟在2020年后的下一次共同农业政策改革期间将高自然价值农田的保护列为优先事项。
