2008 04 Flooding: The Forecast Nick Lyness, Environment Agency SevernEstuary
A presentation was given about the flood risk and environmental impacts of building a Severn Barrage. It was noted that while a barrage could decrease flood risk from storm surges, existing flood defences are sufficient to manage climate change risks without one. A barrage would negatively impact habitats in the Severn Estuary Special Protection Area and proposed Special Area of Conservation. It would require upgrading over 100 drainage schemes at a cost of up to £60 million and could irreversibly impact species like shad that rely on the Severn. Major environmental studies would also be needed given the vast materials required and impacts on permits.

Dams provide many benefits like improving quality of life through irrigation, flood control, hydropower, and more. However, they can also negatively impact the environment and human populations. Key impacts include displacing many people worldwide and inadequate compensation, harming terrestrial and aquatic ecosystems by blocking animal migrations and altering natural river flows, and emitting greenhouse gases from reservoirs. While dams provide irrigation and hydropower, their construction often undercounts displaced people and fails to fully resettle them, compromising livelihoods. Cultural heritage sites can also be damaged or lost. Mitigation efforts are often insufficient to address these social and environmental impacts.
