  1. Insert photo of healthy local/regional reef here! Natural Solutions for Climate Change Impacts in Tropical Seas Presentation Courtesy of Rod Salm & The Nature Conservancy

  2. New challenges from climate change Warmer Seas Rising Seas Disease Altered Currents Stronger Storms Acidification Insert photo of local species of healthy coral

  3. What is lost when corals die? Insert series of 3 photos – 1st a healthy reef, then a degraded reef, then a photo of effects of damaged reef (like coastal damage from storm) – over top the 2nd and 3rd photo place the text ‘People Lose’

  4. Nature’s Infrastructure provides … Multiple direct benefits: • Shoreline protection, food, jobs, carbon sequestration (mangroves) • Sustainable development Cost effective, sustainable solution: • Value of coral reefs: $31 – 600 thousand/sq. km • Shoreline protection cost: $250,000 – $15 million/km

  5. What resilience looks like for corals high cover high diversity low disease broad size range Insert photo of healthy reef here Insert photo of healthy reef here strong recovery good substrate good water quality healthy herbivores

  6. What resilience looks like for mangroves Insert photo of mangrove propagules in abundance or a close up of large stand of mangroves high recruitment high diversity dense stands Insert aerial photo of mangrove forests established zones room to expand good hydrology

  11. Effective Management Threat Abatement Adaptive Strategies Strong Recruitment Enhanced Recovery Control threats – reduce stress Include several photos of local threats (e.g., fishing, industry,heavy tourism, etc.)

  12. The Coral Triangle

  13. Resilience in practice: Kimbe Bay, Papua New Guinea Large, well defined bay (140 x 70 kms)

  14. © TNC © TNC Kimbe MPA network design objectives • To maximize biological objectives by taking into account key biological and physical processes • To maximize benefits and minimize costs to local communities and sustainable industries

  15. Kimbe MPA network design principles • Conserve representative examples of each habitat type • Aim to include a least 3 replicates and 20% of the area of each bioregion • Include special and unique areas including: • areas more resistant / resilient to coral bleaching • areas that support high species diversity • System wide approach that recognizes patterns of connectivity within and among ecosystems • Include entire biological units (e.g., whole reefs) • choose bigger over smaller areas

  16. Kimbe MPA network management principles • Engage communities and get their support • use traditional management framework if possible • Keep reefs healthy through effective management • healthy reefs more likely to survive major impacts • Consider both sea- and land-based threats

  17. Kimbe MPA network design process • 02/04-07/06 • 1st science workshop  objectives, boundaries, design principles • Priority research  minimum data for design  best data in GIS layers • 2nd science workshop  GIS data layers revised • MARXAN analysis  network design options • 3rd science workshop  scientific network design • 07/06-present • Finalize, negotiate network design with stakeholders • Implementation

  20. A Leadership Role for Your Country Your Government policies can: Support resilience research & field applications Ensure that nature-based adaptation is: • Integral to CC adaptation & development programs • Adopted internationally as a viable, good investment • Key component of international framework on CC

  21. If the perils of our time are unprecedented, then so are the opportunities. – Anonymous Insert photo of healthy reef here
