Ecosystem Services of Rivers: The Don River (Russian Federation) and the Roanoke River (USA)

摘要

The concept of ecosystem services recognizes the services, and benefits, provided to people by ecosystems. River systems provide many services to people, including freshwater provisioning, carbon storage, fisheries, recreation, transportation, and hiodiversity. Here, we review the services provided by rivers and describe a conceptual model relating services to drivers, pressures, ecosystem state, and management responses. This approach allowed us to highlight how policies and decisions can lead to trade-offs among services, which must be considered for sustainable watershed management. We have used this conceptual framework to compare two rivers, the Don River in the Russian Federation and the Roanoke River in Virginia/ North Carolina, USA, to demonstrate the usefulness of the ecosystem services approach. Future science needs for ecosystem services in rivers are to identify service indicators and map services, link drivers/pressures to services with models, and relate natural systems to social and economic systems.
