环保科学家警告说，可再生能源基础设施对以地区为基础的保护构成了威胁。在这里，我们表明，目前和近期的两种土地利用的重叠不需要像以前建议的那样严重。这一点很重要，因为全球努力使能源系统脱碳是减缓气候变化和预计气候变化对生物多样性的强烈负面影响的核心。保护区和可再生能源发电分别是应对生物多样性丧失和气候变化的重要工具。在未来几十年中，保护区网络的扩大将伴随着可再生能源基础设施的快速部署以实现气候目标，从而推动有限土地资源的潜在冲突。可再生能源基础设施可能对野生动物产生负面影响，同时出现可能意味着以牺牲保护目标为代价来实现排放目标。在这里，我们使用空间上明确的风能和太阳能数据以及预测未来可再生能源扩张的方法，评估了全球九个地区风能和太阳能光伏装置以及重要保护区的当前和预计重叠。我们显示了与以前的研究相似的共现水平，但表明一旦考虑到面积，以前对北方半球重叠的担忧可能在很大程度上是没有根据的，尽管在一些生物多样性国家（例如，巴西）。这里所提出的两种土地使用之间的重叠的未来预测通常取决于优先阈值和区域，并表明未来冲突的风险可能很低。我们使用有关保护区退化的最佳可用数据来证实这种风险水平。总之，我们的研究结果表明，虽然可再生能源和保护区之间的冲突不可避免地发生，但可再生能源是能源部门脱碳的一个重要选择，如果采用适当的政策和监管控制，不会显著影响基于区域的保护目标。
Conservation scientists warn of the threat to area-based conservation posed by renewable energy infrastructure. Here, we show that the current and near-term overlap of the two land uses need not be as severe as previously suggested. This is important, as global efforts to decarbonize energy systems are central to mitigating against climate change and the strong negative impacts of projected climate change on biodiversity. Protected areas and renewable energy generation are critical tools to combat biodiversity loss and climate change, respectively. Over the coming decades, expansion of the protected area network to meet conservation objectives will be occurring alongside rapid deployment of renewable energy infrastructure to meet climate targets, driving potential conflict for a finite land resource. Renewable energy infrastructure can have negative effects on wildlife, and co-occurrence may mean emissions targets are met at the expense of conservation objectives. Here, we assess current and projected overlaps of wind and solar photovoltaic installations and important conservation areas across nine global regions using spatially explicit wind and solar data and methods for predicting future renewable expansion. We show similar levels of co-occurrence as previous studies but demonstrate that once area is accounted for, previous concerns about overlaps in the Northern Hemisphere may be largely unfounded, although they are high in some biodiverse countries (e.g., Brazil). Future projections of overlap between the two land uses presented here are generally dependent on priority threshold and region and suggest the risk of future conflict can be low. We use the best available data on protected area degradation to corroborate this level of risk. Together, our findings indicate that while conflicts between renewables and protected areas inevitably do occur, renewables represent an important option for decarbonization of the energy sector that would not significantly affect area-based conservation targets if deployed with appropriate policy and regulatory controls.
