2. • Coastal Systems Focus: on Coastal Flooding- PNG Context
• Papua New Guinea has approximately 20,000km of coastline which
is vulnerable to coastal flooding.
• From analysis in 2010, it was estimated that it affects 6000 people,
displaces 400, and kills several people annually.
• Further estimated
that coastal flooding
causes USD 7-8
million in direct
damage.
• Climate change is
anticipated increase
the frequency and
intensity of coastal
flooding- immediate
action required.
3. Adaptation Options for Coastal
Flooding:
• Set Up an Early Warning System
• Plant Mangroves
• Construct Sea Walls
• Deciding Factors
• # of lives protected
• Cost/ Benefit
4. Initiatives to Address Coastal
Flooding
• Awareness & Education
• billboards on the services that Mangroves provide for
coastal protection; encouraging people to preserve
• Supplementary teaching materials for gr 6-8, on climate
change, including coastal flooding
• Early Warning
• Flood early warning system piloted in 5 Provinces
• Mapping to show inundation levels for planning
5. Mangrove
Planting
• Timeframe:
2011
• Mangrove Workshop : success
of mangrove planting is not
good- often because wrong
types of mangroves are being
planted in the wrong area.
• Guidance on planting needed
to improve chances of success
mangrove handbook
2012-2014
• drafting, revising, printing of
handbook.
2014- present
• handbook is being used in
communities.
6. About MangrovePlanting Handbook
Step-by-step guide on how to rehabilitate mangroves. Motivation behind
the handbook is to address coastal flooding on communities from climate
change but it can be used to plant mangroves for conservation, fisheries,
eco-tourism or others. The process of planting mangroves are split into 6
stages in the book:
• Rationale
• Planning and site analysis
• Implementation
• Ensuring survival
• Awareness and training
• Funding
Templates for workplans; awareness; budgeting;
Seeking funding support, examples of nursery designs etc.
Has been in use since 2014 to train communities in 6
Provinces in PNG. The training is supported by the
Adaptation Fund and UNDP.
7. Lessons
Time to produce- (4 years) from idea to final product.
Support came from Adaptation Fund, Wildlife
Conservation Society & Mama Graun Trust Fund (local
NGO) to edit & publish. CCDA took the lead and it was
all done in PNG.
Success or Not?Has
handbook helped
communities reduce
the impact of coastal
flooding? Have yet to
follow-up to find this
out.
Economic Analysis
Was done for PNG by
Mckinsey in 2010.
Almost 10 years old.
Was useful at the time,
but we want to be able
to produce that type of
analysis in country now,
through local expertise.
