随着电力部门从碳密集型化石燃料过渡,水电继续在全球范围内扩张。新的坝址对自然生态系统和人类生计的不利影响程度差别很大。在这里,我们讨论了如何战略规划的水电扩建可以帮助决策者比较建设大坝的社会环境影响的好处。数据可用性和计算分析的进步现在能够在越来越大的空间尺度上解释越来越多的社会和环境指标。反过来,扩大规划的空间规模,在寻求改善经济和社会环境成果方面产生更多的选择。仍然迫切需要将气候变化纳入水电规划。最后,这些在评估潜在坝址方面的创新应纳入整个能源系统的战略规划,以确保最大限度地减少对河流系统的社会和环境破坏。
Hydropower continues to expand globally as the power sector transitions away from carbon-intensive fossil fuels. New dam sites vary widely in the magnitude of their adverse effects on natural ecosystems and human livelihoods. Here, we discuss how strategic planning of hydropower expansion can assist decision makers in comparing the benefits of building dams against their socioenvironmental impacts. Advances in data availability and computational analysis now enable accounting for an increasing array of social and environmental metrics at ever-larger spatial scales. In turn, expanding the spatial scale of planning yields more options in the quest to improve both economic and socioenvironmental outcomes. There remains a pressing need to incorporate climate change into hydropower planning. Ultimately, these innovations in evaluating prospective dam sites should be integrated into strategic planning of the entire energy system to ensure that social and environmental disruption of river systems is minimized.
