Disaster risk reduction / management
Legislation
• Civil Defence Emergency Management Act 2002
• National CDEM Strategy
• Canterbury CDEM Group Plan
• Resource Management Act 1991
• Canterbury Earthquake Recovery Act 2011
• Recovery Strategy

When the domain of Tāne and Tangoroa
are nurtured and sustained, so too will the
people prosper and flourish.

21. Disaster risk reduction / management

22. The Hyogo Framework for Action seeks to
“encourage the sustainable use and
management of ecosystems, including
through better land-use planning and
development activities to reduce risk and
vulnerabilities.”
It promotes the implementation of
“integrated environmental and natural
resource management approaches that
incorporate disaster risk reduction …”

23. Community expectation

25. Recovery Strategy
Natural Environment Recovery Goals
Restore the natural environment to support biodiversity and economic
prosperity and to reconnect people to the rivers, wetland and Port Hills – by:
• Ensuring recovery activities value, protect and sustainably manage the sources of
our water
• Ensuring ecosystems are healthy and functioning to support biodiversity and
economic growth
• Improving the quality and function of estuaries, waterways and wetlands to
support the unique biodiversity that is endemic to Te Waipounamu
• Providing safe public access to and opportunities for outdoor recreation,
cultural, social and economic activities
• Enhancing air quality through managing recovery activities that impact on air
quality, such as heating, transport, demolition and construction
• Storing, sorting and processing waste in an environmentally safe and effective
manner, including minimising and recycling construction and demolition wastes

26. Area covered by NERP
Greater Christchurch (as defined in CERAct 2011)
Focus on areas most affected
by the earthquakes
• coastal urban area
• lowland streams and rivers
• Port Hills
• Lyttelton Harbour/ Whakaraupō

27. Vulnerability
• Development near
coast, waterways
and on Port Hills
• Centralised
infrastructure
• Limited readiness
• Low local social
capital
Hazard
• Earthquake
• Liquefaction
• Lateral Spread
• Land tilt
• Rockfall
• Cliff collapse
• Landslide
• Flooding

31. Strategic partner collaboration
Community involvement
Technical Advisory Group
• Partner organisations
Community - stakeholders
• Community organisations/NGOs, Councils, Universities, Crown
Research Institutes, Consultants
• Stakeholder workshops October, 2012 December 2012 - facilitated
by ESR. Reports at www.ecan.govt.nz/nerp

32. What is in the
programme?

34. NERP projects
17 projects:
• Actions
• Do nothing
• Prevent further damage
• Rehabilitate
• Take opportunities
• Increase resilience and sustainability
• Lead agencies and partners
• Timelines and priority
• Indicative costs

35. • Programme leader position
• 3-year contract
• jointly funded by ECan, CCC, WDC, SDC
• Quarterly reports on NERP progress
• Promote collaboration on projects
• Facilitate Technical Advisory Group
• Plan transition for after 2016
What now? - implementation

43. Food resilience network

44. How are we doing?
? Speedy recovery  legislation changed  less community
consultation
? Avoiding development in hazardous areas - priority for
land for new housing
? Infrastructure - replacing ‘like-with-like’ - opportunity lost
for more sustainable and resilient systems
? Flood capacity vs ecological improvement
? Waste - reuse, recycling, separating waste at source
? Climate change and sea level rise
? Sustainable buildings
? Low impact design

45. So what? We should all…
Plan for recovery of the natural environment
before a disaster that
• is integrated with other recovery planning
• involves agencies and community
organisations
• anticipates the consequences of hazards on
ecosystems, and identifies options for
responding
• takes an integrated approach to disaster risk
reduction and ecosystems management
