Ten projects designed to highlight good practice in tackling coastal erosion have secured a share of more than £1m from the Scottish Government’s Coastal Change Adaptation Programme.
Due to be delivered in 2024-25, the projects cover eight local authority areas and include plans to enhance natural defences to help reduce the rate of erosion and improve protection from flooding, such as at Kingston in Moray.
The funding – part of £12m committed for coastal change adaptation during the course of the current Parliament – will also be used to support engagement with local people, businesses and infrastructure owners on the process for developing coastal change adaptation plans, and for improvements to the monitoring of coastlines.
Cabinet Secretary for Transport, Net Zero and Just Transition Màiri McAllan said: “The climate emergency is not a distant threat – we are already seeing an increased impact on coastal communities due to adverse weather and rising sea levels.
“We need to start adapting our coasts to better respond to sea level rise and reduce the risks associated with coastal erosion. Local authorities are seizing the opportunity to do this essential work, with their communities as key partners, and I am confident this additional funding will support that work even further.
“These case studies will be an important source of knowledge for all areas in Scotland affected by coastal change and will help to inform future projects.
“We are already bringing forward measures to help protect homes, the natural environment and agriculture from climate change. And we’re providing £150 million of extra funding, on top of our annual £42m funding, for flood risk management over the course of this Parliament.
“We will continue to work with our local authority partners, communities and businesses to adapt our coastlines to climate change.”
Later this month the new National Adaptation Plan to address the climate risks facing Scotland will be published.
A consultation on a new Flood Resilience Strategy will also be published for views this year.
SEPA is introducing new flood hazard mapping which will provide a clearer indication of surface water (also known as pluvial) flood risk now and in future. This will enable people, communities and businesses to better understand the risks and act to reduce the impact of surface water flooding.
The introduction of the new mapping will support delivery of SEPA’s Flooding Services Strategy being published in autumn 2021. It is key to the organisation’s vision of a society that is resilient to flooding and adapted to future climate change.
Surface water flood maps have been publicly available on the SEPA website since 2013, however, our 2018 National Flood Risk Assessment identified surface water as the largest source of flood risk affecting Scotland.
The mapping, which will be provided by JBA Consulting, will provide a complete refresh of our national surface water flood maps using the most up-to-date data on current and future rainfall, improving our flood map products to provide more confident results of where surface water flooding is likely.
The project will involve an initial pilot stage which will trial high resolution modelling and mapping methodologies, and a range of model assumptions and parameters across four pilot areas: Aberdeen, Glasgow, Peebles and Torridon. When the pilot stage ends early next year, an agreed approach will be rolled out across Scotland and the mapping will be produced in a sequence of 11 geographical phases.
Vincent Fitzsimons, Head of Hydrology & Flooding at SEPA, said: “The latest landmark climate change report from the IPCC is a clarion call for what the world already knows, that the climate emergency is accelerating. SEPA is urgently responding to ensure Scotland’s communities and businesses are resilient to flooding and adapted to future climate change impacts.
“A major part of this is to ensure information on flood risk is available to those who need it most. This means we need to continually improve the quality and availability of our flood map products, with a particular focus on surface water flood risk.
“Our significant investment in this project to improve surface water flood hazard mapping for Scotland is one step on the journey to ensure people and businesses are resilient to flooding and adapted to our changing environment.”
David Bassett, Director, JBA Consulting said: “We’re delighted to be appointed by SEPA to complete the national surface water flood hazard mapping for Scotland. We have been working on flood risk in Scotland for over 20 years and in that time our technical experts have accrued excellent knowledge of the risk and the issues, and the structures in place to help.
“Scottish Government surface water management planning guidance issued in 2018, highlighted that 23% of annual average damages associated with flooding across Scotland were forecast to come from surface water flooding. Of the 27,500 homes predicted to be at risk, 39% are in areas of higher social vulnerability.
“Climate change was also predicted to increase the numbers of homes and businesses at risk by 45%.
“With flood events never far from the news headlines, recent surface water flooding in Edinburgh showed the vulnerability of many urban areas. The role of consistent 2m grid surface water flood risk mapping across Scotland is more important than ever, and we’re pleased to lead on this national mapping project.”
Support to protect Scotland’s coastlines
New maps forecast impacts of climate change
An estimated £1.2 billion of Scotland’s buildings, transport infrastructure, cultural and natural heritage may be at risk of coastal erosion by 2050, according to new research.
As part of the Scottish Government’s Dynamic Coast project, funded by the Centre of Expertise for Waters (CREW), the University of Glasgow has developed new maps to serve as a coastal change adaptation planning tool for government, agencies, local authorities as well as communities and businesses.
With evidence from the maps, the government is encouraging local authorities to prepare coastal adaptation plans, supported by an additional £12 million of investment. In recognition of the heightened landscape of climate-related risk in Scotland, Dynamic Coast will form part of a wider national programme to build resilience.
The Scottish Government has also already announced plans to host a National Climate Resilience Summit in the Autumn, to raise awareness and build momentum across the public and private sectors in advance of COP26.
Net Zero Secretary Michael Matheson visited the sand dunes in Montrose, which help protect the town from coastal flooding and erosion.
Mr Matheson said: “I welcome the publication of Dynamic Coast 2 which shows us that at least £20 billion of assets, road, rail and residential property, lie within 50 metres of our coast. With nature protecting some £14.5 billion of these assets, maintaining our natural coastal defences must be a key part of our resilience and adaptation strategies.
“We are already locked into future sea level rise and therefore we must plan for the worst case scenario on the coast. Modelling suggests however that we will see erosion influencing the majority of shores this decade. The Dynamic Coast maps will be a valuable tool in our fight against climate change, and we are now preparing guidance to help local authorities produce new adaptation plans.
“Here in Montrose, up to 80 metres of beach has eroded since the 1980s and a further 120 metres could erode over the next 40 years, breaching the main dune ridge. Angus Council is working with local stakeholders, including Montrose Port Authority and Montrose Golf links to identify the most sustainable solution for the town.
“COP26 in Glasgow represents the world’s best chance – perhaps one of our last chances – to avert the worst impacts of climate change. However, even in the best case scenario for global emissions reductions it is clear that we must also be preparing for the impacts that are already locked in.
“By doing this we can deliver on the principles of the Paris Agreement with lasting action to secure a net zero and climate resilient future in a way that is fair and just for everyone.”
NatureScot Climate Change Director Nick Halfhide said: “This latest research from Dynamic Coast highlights that natural defences, such as sand dunes, protect three times the value of roads, railways and buildings than sea walls do.
“That’s why we must invest in Scotland’s nature. Nature based solutions are essential in our response to the twin crises of nature loss and climate change, and with COP26 coming to Glasgow in the coming months, there’s no better time for Scotland to take ambitious action.”
Director of the Centre of Expertise for Waters (CREW) Professor Bob Ferrier said: “CREW is delighted to have supported the development and launch of the Dynamic Coast project.
“This nationally significant research will assist decision-makers and others to understand how Scotland’s coastal assets need to adapt to the pressures of climate change and improve our collective resilience in the face of this challenge.”
