Climate change and biodiversity loss are pressing global challenges(Pörtner et al.,2021).However,as global energy demand continues to increase(IEA,2021),nations face significant challenges to decarbonization and reaching“net zero”due to trade-offs between the often-competing needs of renewable energy generation and biodiversity *** example,hydropower generates renewable energy(Gibson et al.,2017),yet there are well-documented and severe consequences of dam development for biodiversity(e.g.,Zarfl et al.,2019)and people(e.g.,Bisht,2009)due to reservoir creation and disruption of river *** such potentially damaging ecological and social trade-offs,hydropower currently contributes 70%of global renewable energy and there are at least 3700 large dams planned or under construction globally(Zhang&Gu,2023).
