Preparing for Sea-Level Rise Through Adaptive Managed Retreat of a New Zealand Stormwater and Wastewater Network
infrastructures Article Preparing for Sea-Level Rise through Adaptive Managed Retreat of a New Zealand Stormwater and Wastewater Network Rick Kool 1,2, Judy Lawrence 1,* , Martin Drews 2 and Robert Bell 3 1 New Zealand Climate Change Research Institute, Victoria University of Wellington, 6012 Wellington, New Zealand; [email protected] 2 Department of Technology, Management and Economics, Technical University of Denmark, 2800 Kgs. Lyngby, Denmark; [email protected] 3 National Institute of Water and Atmospheric Research, 3251 Hamilton, New Zealand; [email protected] * Correspondence: [email protected] Received: 6 October 2020; Accepted: 16 October 2020; Published: 1 November 2020 Abstract: Sea-level rise increasingly affects low-lying and exposed coastal communities due to climate change. These communities rely upon the delivery of stormwater and wastewater services which are often co-located underground in coastal areas. Due to sea-level rise and associated compounding climate-related hazards, managing these networks will progressively challenge local governments as climate change advances. Thus, responsible agencies must reconcile maintaining Levels of Service as the impacts of climate change worsen over the coming decades and beyond. A critical question is whether such networks can continue to be adapted/protected over time to retain Levels of Service, or whether eventual retreat may be the only viable adaptation option? If so, at what performance threshold? In this paper, we explore these questions for stormwater and wastewater, using a dynamic adaptive pathway planning (DAPP) approach designed to address thresholds and increasing risk over time. Involving key local stakeholders, we here use DAPP to identify thresholds for stormwater and wastewater services and retreat options, and for developing a comprehensive and area-specific retreat strategy comprising pathway portfolios, retreat phases, potential land use changes, and for exploring pathway conflicts and synergies. -
Climate-Driven Community Relocations in the Solomon Islands and Alaska Provide Insight for a 1.5 °C Future
Regional Environmental Change https://doi.org/10.1007/s10113-017-1256-8 ORIGINAL ARTICLE Heading for the hills: climate-driven community relocations in the Solomon Islands and Alaska provide insight for a 1.5 °C future Simon Albert1 & Robin Bronen2 & Nixon Tooler 3 & Javier Leon4 & Douglas Yee5 & Jillian Ash6 & David Boseto7 & Alistair Grinham1 Received: 4 May 2017 /Accepted: 12 November 2017 # Springer-Verlag GmbH Germany, part of Springer Nature 2017 Abstract Whilst future air temperature thresholds have become the centrepiece of international climate negotiations, even the most ambitious target of 1.5 °C will result in significant sea-level rise and associated impacts on human populations globally. Of additional concern in Arctic regions is declining sea ice and warming permafrost which can increasingly expose coastal areas to erosion particularly through exposure to wave action due to storm activity. Regional variability over the past two decades provides insight into the coastal and human responses to anticipated future rates of sea-level rise under 1.5 °C scenarios. Exceeding 1.5 °C will generate sea-level rise scenarios beyond that currently experienced and substantially increase the propor- tion of the global population impacted. Despite these dire challenges, there has been limited analysis of how, where and why communities will relocate inland in response. Here, we present case studies of local responses to coastal erosion driven by sea- level rise and warming in remote indigenous communities of the Solomon Islands and Alaska, USA, respectively. In both the Solomon Islands and the USA, there is no national government agency that has the organisational and technical capacity and resources to facilitate a community-wide relocation. -
Four Strategies for Dealing with Sea Level Rise
Sea level Rise Adaptation Tools and Resources Did you know….? Canada has the longest coastline in the world – approximately 151,019 miles (243,041.5 km) In British Columbia, 80% of population lives within 5 km from the coast. 59 municipalities out of 169 municipalities are coastal, 14 out 28 regional Districts contain coastal communities. The length of the coast is approximatively 29,000 km including the mainland and all islands from Haida Gwaii south to Vancouver Island and the Gulf Islands Coastal population: 3,500,000 Major ports: Metro Vancouver, Prince Rupert and Victoria In BC, the government is planning for Sea Level Rise (SLR) using this projected data: 0.5m sea level rise by 2050, 1m by 2100 and 2 m by 2200 BC communities won't be affected by sea level rise in the same way due in part to vertical land movement. The highest relative sea level rise is projected to occur in the Fraser low land, the southern part of Vancouver Island and the North Coast of British Columbia The greatest threat to communities along the coast besides sea level rise is storm surge flooding. Coastal communities are already dealing with extreme water levels.

Improving the Prospect for Managed Retreat by Us Cities

Communicating Managed Retreat in California

Management plans are often designed to prevent or slow flooding with short-term, defensive strategies such as shoreline hardening, beach nourishment, and living shorelines. By contrast, managed retreat focuses on avoiding hazards and adapting to changing shorelines by relocating out of harm’s way. However, the term “managed retreat” can be controversial and has engendered heated debates, defensive protests, and steady resistance in some communities. Such responses have stymied inclusion of managed retreat in adaptation plans, and in some cases has resulted in complete abandonment of the policy review process. We examined the Local Coastal Program review process in seven California communities at imminent risk of sea-level rise and categorized each case as receptive or resistant to managed retreat. Three prominent themes distinguished the two groups: (1) inclusivity, timing, and consistency of communication, (2) property ownership, and (3) stakeholder reluctance to change. We examined use of terminology and communication strategies and provided recommendations to communicate “managed retreat” more effectively. -

Development Control Guidance Note: Development and Coastal Erosion – April 2009 2 Summary
North Norfolk Development Control Guidance Development and Coastal Erosion April 2009 Development Control Guidance Note: Development and Coastal Erosion – April 2009 2 Summary North Norfolk District Council, as coast protection authority, manages erosion risk, but it also has a broader responsibility for ensuring that the interests of the public and of our coastal communities are safeguarded in the face of coastal change. Development is a normal and necessary process by which private and commercial aspirations are achieved and community needs are met. It is essential that coastal communities are no different from those inland, and this guidance has therefore been prepared to help ensure that coastal change can be managed now and in the future with minimal detriment to the communities at risk. Protection against flooding is the responsibility of the Environment Agency and whilst this can present a similar threat to individuals and communities it is more difficult to predict and usually its impacts are less permanent. Coastal flooding therefore requires a different response and is dealt with by different policies and guidance; this guidance relates only to coastal erosion (for the cliffed frontage of North Norfolk’s coastline). Planning policy at a national level, and in our own Local Development Framework, stresses that new development should be avoided in coastal zones at risk of erosion. National Planning Policy Guidance Note 20 says a “precautionary approach” should be taken in areas susceptible to erosion. The Regional Spatial Strategy seeks to ensure that “new development is compatible with shoreline management”. And NNDC’s Core Strategy aims to “restrict new development in areas where it would expose people and property to the risks of coastal erosion and flooding”.
