Context
Drivers for relocation
4
Taro Island very low lying
Major coastal hazards:
tsunami
coastal storms and storm tide inundation
shoreline erosion
Climate change & sea level rise impacts
Limited land supply
Largest centre (900 residents) serving catchment of 26,000 people.
Land acquired for new township site
Drivers for relocation
5
Shift in position from ‘expansion’ to ‘relocation’ .
Limited space for refuge in 2014 from tsunami and virtually no space by 2090 due to SLR.
People evacuating by boat to mainland
Community engagement revealed: people fearful of tsunami
people seeing changes in ocean and loss of land
strong desire to relocate from Taro Is, not just expand.
Need action plan to manage existing and future risks and relocation.

Choiseul Bay Township Climate Change Adaptation Plan
A plan has been prepared that:
shows how climate change hazards are likely to affect Taro Island and new town site;
makes recommendations about how to protect the community and important areas from hazards & improve resilience;
guides how and when new development & relocation should occur in future.
Choiseul Bay Township Climate Change Adaptation Plan
Natural hazard mapping:
- defined and quantified natural hazards
- time periods: 2014, 2030, 2055 and 2090
- used SLR projections based on 5th (IPCC) report
Risk assessment and adaptation options
Vision and planning scheme
Adaptation Plan including schedule of works for relocation of capital

Choiseul Bay Township Climate Change Adaptation Plan
Community engagement Community & political
ownership essential for
successful implementation
Fundamental to every stage of
climate change adaptation
planning
Engagement strategy for ‘whole
of community’
10
In total, the project team spoke to over 300 community members!
Community engagement
• Lead the community on a ‘technical journey’
• Make complex things simple
• Draw out and validate community values
• Show how feedback was reflected in:
- Adaptation options
- Vision and planning for new town
• Highly graphical engagement materials
• English is not their first language “The project followed the ways
of our traditions – talking with people, listening to people and reflecting the desires of the people.”

Community engagement Community ownership important
because: risk assessment is subjective and relies on
judgement decisions to assign likelihood and consequence levels.
community engagement used to validate and refine risk assessment outcomes
Community engagement also ensures: local knowledge is reflected in adaptation
options options are practical, realistic and
implemented within means and financial constraints of community
options fit for purpose and acceptable to community to optimise chances of implementation.

Vision for New Provincial Capital
A Strategic Plan for the New Choiseul Bay Town
Implementation Now reviewing town layout against topographic
survey of Lot 277.
Project office being set up and project planner on Taro by end of 2015.
Priority tasks:
- Follow up community engagement
- Rainwater tanks to increase water supply
- Review program of works
- Source funds for works and studies
- Gazettal of local planning scheme
- Emergency Response Plan & refuge shelter
- Dilapidation audit of buildings and infrastructure
- Commence negotiations with customary landowners for land and sea access

Site Analysis
Site Analysis
Integrating hazard and risk assessments into planning
– Planning scheme, a key statutory tool
– Shape and layout of town based on 2090 hazard mapping
– Emergency evacuation informed planning outcomes
– Direct where development can occur and ‘no go’ areas – avoidance option
– Identify zones and uses that respond to risk and constraints
– Embed across all levels of scheme: • Vision & strategic policy to relocate over time
• Detailed provisions eg: design & location requirements for hospital, tsunami refuge shelter and interim uses
• Protecting reefs and mangroves

What made the project successful? Multi-disciplinary team essential for integration of science, engineering,
planning, community engagement and local knowledge
Community engagement strategy – key tool
Communicated key messages of science & risk simply - relied on highly graphical materials
Community input, ownership and understanding – all stages
Vision & community values – very powerful
Good natural hazard mapping essential - define extent and likelihood
Highly localised information was geo-referenced into GIS to inform planning
Understand risk and consequences over time and integrate across all levels of planning
Focus on priority risks and stage actions & planning responses
Adaptation actions ‘fit for purpose’
Strongly reflects community feedback and embeds this into adaptation actions and planning for new town.
