进一步基于水库的水电开发可以促进联合国关于负担得起的清洁能源和气候行动的可持续发展目标(SDGs)。然而，水电站水库的运行可能会对生物多样性造成影响，从而干扰关于清洁水和陆地生命的可持续发展目标。我们将高分辨率、特定位置的技术评估与新开发的生命周期影响评估模型相结合，以评估未来可能的水电站因占地、用水量和甲烷排放而产生的潜在生物多样性影响。我们的研究表明，谨慎选择水电站水库具有限制生物多样性影响的巨大潜力，例如，全球水电潜力的0.3%占陆地生物多样性影响的25%。当地变化，例如物种丰富度，是量化的生物多样性影响差异的主要解释因素，而不仅仅是耗水量或每千瓦时占用的土地。生物多样性的影响主要是由土地占用和水消耗造成的，甲烷排放的影响要小得多。此外，我们指出了陆地和水生生物多样性影响之间的权衡风险，因为由于陆地和水生生物多样性影响之间的相关性较弱，水生生物多样性影响较小的水库往往会产生较大的陆地影响，反之亦然。
Further reservoir-based hydropower development can contribute to the United Nations’ sustainable development goals (SDGs) on affordable and clean energy, and climate action. However, hydropower reservoir operation can lead to biodiversity impacts, thus interfering with the SDGs on clean water and life on land. We combine a high-resolution, location-specific, technical assessment with newly developed life cycle impact assessment models, to assess potential biodiversity impacts of possible future hydropower reservoirs, resulting from land occupation, water consumption and methane emissions. We show that careful selection of hydropower reservoirs has a large potential to limit biodiversity impacts, as for example, 0.3% of the global hydropower potential accounts for 25% of the terrestrial biodiversity impact. Local variations, e.g. species richness, are the dominant explanatory factors of the variance in the quantified biodiversity impact and not the mere amount of water consumed, or land occupied per kWh. The biodiversity impacts are mainly caused by land occupation and water consumption, with methane emissions being much less important. Further, we indicate a trade-off risk between terrestrial and aquatic biodiversity impacts, as due to the weak correlation between terrestrial and aquatic impacts, reservoirs with small aquatic biodiversity impacts tend to have larger terrestrial impacts and vice versa.
