Funding by the Australian Government represented by the Department of Climate Change and Energy Efficiency. Coastal Adaptation Decision Pathways projects - An Australian Government initiative

Peron Naturaliste Partnership

The vision of the Peron Naturaliste Partnership is to empower a resilient regional community to reduce risks and optimise opportunities presented by climate change.

Approach A regional wide approach to making adaptation decisions is critical in ensuring local government take a ‘best shot’ approach to adaptation. The partnership has strengthened cooperation between Local Governments and State Government Communication of climate change to the wider community is crucial A long term approach has been identified as the best way to address coastal erosion and inundation.

Guiding Documentation PNP MOU Agreement March 2011 – March 2013 (to be updated and re-signed in February 2013) PNP Business Plan and Action Plan Draft Communications Strategy Draft Pilot Community Engagement Strategy

Communication Strategy The framework will: link to current best practice initiatives protect the existing partner’s organisational brand, image and reputation provide framework and direction for future consultation and engagement guide external communications guide internal communication and capacity building Knowledge management

Community Engagement Community Education and Capacity Building Media/Communications Public Participation Partnership and Collaboration Stakeholder Workshops Community Forums

Goals The International Association for Public Participation training and education is adopted by Local Governments across Australia and encourages a communicative approach to public participation (IAPP 2007). There are 5 driving goals: Information Consultation Involvement Collaboration Empowerment

Coastal Adaptation Decision Pathways Project - Developing Flexible Adaptation Pathways for the Peron Naturaliste Coastal Region of WA Aim: To ensure the Peron Naturaliste Coastal Region of Western Australia is adequately prepared to respond to the impacts and opportunities posed by climate change

Funding Australian Government (DCCEE): $400,000 Phase One: State Government (Department of Transport): $70,000 PNP Councils: $50,000 Partners Department’s of Transport, Planning, Environment and Conservation and Water

Project Summary Phase I is a synthesis of coastal hazards affecting the region. Phase II is a regional-based assessment of impacts, specifically comparing present day conditions with those projected for Phase III is a detailed locally-based assessment of impacts and potential responses, which will change over time. Developing adaptation options considers real options approach.

Key Messages Innovative approach Erosion hazard mapping utilized has some limitations Erosion modeling needs to be refined Identify rock features Include alongshore controls such as headlands and groynes Primarily an economic assessment

Key Messages Assumed no existing protection Impacts in areas outside the case study areas are not included Uncertainty associated with future climate change impacts in the region Institutional knowledge - PNP

Region-Wide Assessment Developing an understanding of the overall resource cost of adaption within the region as a whole Aim of this phase is not to design strategy but highlight likely costs Assets are classed into several classes and then a single, representative value is applied to all assets in a given class and location of assets is not considered Assets examined at snapshots in time

Region-Wide Assessment Erosion is a far more pervasive issue than flooding 800 hectares of residential land would be subject to an increase in flooding risk Approximately 200 metre wide strip is at risk from erosion along the whole extent of the coastline. The value at risk of the affected assets along this section of coastline is approximately $1.2 billion $1.1 billion of assets are worth saving, at a cost of around $120 million

Region-Wide Assessment Approximately $80 million in assets are not worth saving Equates to around 80 % of the affected region When this farmland and/or nature reserve sits behind more valuable settled areas, the protection afforded to the settled areas will also affect the less valuable land
