Incorporating Ecosystem Services in the Assessment of Water Framework Directive Programmes of Measures.

Environ Manage 2021 07 12;68(1):38-52. Epub 2021 May 12.

Centre for Environmental Policy, Imperial College London, London, UK.

The EU Water Framework Directive requires the development of management responses aimed towards improving water quality as a result of improving ecosystem health (system state). Ecosystems have potential to supply a range of services that are of fundamental importance to human well-being, health, livelihoods and survival, and their capacity to supply these services depends on the ecosystem condition (its structure and processes). According to the WFD, Programmes of Measures should be developed to improve overall water status by reducing anthropogenic catchment pressures to levels compatible with the achievement of the ecological objectives of the directive, and when designed and implemented properly should improve the ecological condition of aquatic ecosystems that the delivery of ecosystem services depends on.
