Three major steps toward the conservation of freshwater and riparian biodiversity

Conservation Biology, Volume 38, Issue 3, June 2024.
Abstract Freshwater ecosystems and their bordering wetlands and riparian zones are vital for human society and biological diversity. Yet, they are among the most degraded ecosystems, where sharp declines in biodiversity are driven by human activities, such as hydropower development, agriculture, forestry, and fisheries.
