- Abstract:
- Sea-level rise is one of the most profound aspects of human-induced climate change and its steady but uncertain rate of rise will transform the world's coasts in the coming decades threatening millions of coastal and flood plain residents. While this is understood in a technical sense, wider society has not grasped the scale of change produced by expected rise in sea level over the next century. In the UK, with its large legacy of coastal defences, this issue is especially challenging. Many defences are uneconomic to maintain and renew, and widespread 'realignment' is planned within the strategic process of Shoreline Management Planning (SMP). Realignments reactivate natural sediment processes which enhances self-adjusting natural protection with both risk-reduction and aesthetic benefits. However, the transformation from a defended to a realigned coast is especially challenging to implement and will be an important focus of this research. There has been surprisingly little consideration of how the transition to a realigned coast can be facilitated and enabled across the full range of physical and social perspectives. Efforts to better understand the full range of adaptation options and their implementation, including realignment, offer potentially significant rewards in terms of tangible enhancement of coastal resilience. CoastalRes aims to develop and demonstrate prototype methods to assess realistic pathways for strategic coastal erosion and flood resilience in the light of climate change, including sea-level rise. We will accomplish this aim via three objectives. Objective 1. Co-produce a comprehensive set of representative coastal archetypes that describe the open and estuarine coasts of England and Wales in terms relevant to building coastal resilience, including present and future demography, hazards, sea-level rise, contrasting geomorphology, shoreline position, land use patterns and management legacy. This will include early and fully participatory engagement with stakeholders to consider their knowledge and experiences and define the full range of archetypes. Objective 2. Identify and evaluate a comprehensive range of strategic high level adaptation options, considering their physical suitability, economic efficiency, social acceptability and pathways of application (potential sequence in time) and impact on UK resilience. This will include a systematic literature-based review combined with two regional stakeholder workshops organised with the Coastal Group Network and the Environment Agency. Objective 3. Taking three common and representative coastal archetypes, design decision pathways to maintain and enhance resilience based on the menu of adaptation options. This will include consideration of a range of factors including policy choices, cost implications, risk trade-offs and public participation in problem specification and decision making. These adaptation pathways for resilience will be validated with representative real sites. The use of coastal archetypes for the analysis, rather than case studies, is novel and allows generalisation from individual cases to develop generic and transferable guidance. Crucially, our analysis considers all the open coasts and estuaries in England and Wales, as estuaries contain a large proportion of the assets and activities exposed to marine flooding. In contrast to previous work, which has tended to rely on consultation and 'outreach' to stakeholders, our research will have a genuinely participatory approach. This will allow us to achieve a consensus understanding with a large and diverse group of relevant Project Partners, including the key organisations the Environment Agency and Maritime District Authorities. The CoastalRes Project will provide a solid demonstration of a transition to a more balanced, resilient and sustainable portfolio of adaptive options on the UK coast and provide a foundation for further research in this area.
