I agree. My local authority is very concerned by negative RSG, not just the disappearance of RSG. Negative RSG would mean having to pay more to support other areas.

The council’s collaborative work has achieved high levels of third-party investment and led to better coastal protection. My hon. Friend is right that we need to properly fund our coastal areas. At East Head and at Pagham harbour, coastal advisory groups run the UK’s only two active management sites. Both sites have a highly dynamic coastline, so predicting erosive and flood patterns can be very challenging. Active management involves long-term monitoring and observation to ensure interventions are effective and in tune with the natural processes.

The regional coastal monitoring programme, based in Southampton, is key to that process, providing data on waves, tides and the changing nature of the coastline. Armed with that data, the group can make decisions on interventions such as replacing or removing failing structures or replenishing beach sediments. Such is the success of the programme that natural changes at Pagham since 2016 have removed the threat to residents in the short term and introduced an intertidal wetland habitat that is now a Royal Society for the Protection of Birds nature reserve.

The council receives a grant of £250,000 a year. That funding allows it to protect people, business and habitats. Over recent years, the Environment Agency has invested a further £30 million as part of its flood and coastal erosion risk management at Medmerry, where the UK’s first managed realignment site is ongoing. West Wittering, where erosive processes are mitigated to maintain the beach, attracted around 800,000 visitors last year, driving the local economy and simultaneously helping protect the internationally important saltmarsh environment sheltered by East Head spit.

There is still significant concern in my area, however. In the long term, the council has warned that highly populated areas such as Selsey, Bracklesham and East Wittering will eventually require significant investment.
