Securing access to energy for a growing population under the international commitment of reduction of greenhouse emissions requires increasing the contribution of renewable sources to the global share. Hydropower energy, which accounts for >80% of green energy, is experiencing a boom fostered by international investment mainly in developing countries. This boom could be further accelerated by the recent climate agreement reached in Paris. Despite its flexibility, hydropower production entails social, economic and ecological risks that need to be carefully considered before investing in the development of potentially thousands of planned hydropower projects worldwide. This is especially relevant given the weak or nonexistent legislation that regulates hydropower project approval and construction in many countries. I highlight the need for adequate policy to provide the Paris Agreement with new financial and planning mechanisms to avoid further and irreversible damage to freshwater ecosystem services and biodiversity.
为了在减少温室气体排放的国际承诺下，保障不断增长的人口的能源供应，需要增加可再生能源在全球能源份额中的贡献。水力发电能源占绿色能源的 >80%，正在经历一场由国际投资推动的繁荣，主要集中在发展中国家。最近在巴黎达成的气候协议可能会进一步加速这一繁荣。尽管水力发电具有灵活性，但在投资开发全球数以千计的潜在水力发电项目之前，需要仔细考虑其带来的社会、经济和生态风险。鉴于许多国家在水力发电项目审批和建设方面的立法薄弱或不存在，这一点尤为重要。我强调需要有适当的政策，为《巴黎协定》提供新的财务和规划机制，以避免对淡水资源生态系统服务和生物多样性造成进一步的和不可逆转的损害。
