Transcript of "Coral Reefs and Sustainable Management"

  1. 1. The Biosphere: Coral Reefs
  2. 7. <ul><li>Tropical latitudes </li></ul><ul><li>Warm water >24 Degrees C) </li></ul><ul><li>Lack of seasonality </li></ul><ul><li>Less developed nations </li></ul><ul><li>Nutrient-less (clear) water </li></ul>Where are coral reefs located?
  3. 8. <ul><li>Coral is really two organisms living together and helping each other </li></ul><ul><ul><li>Zooxanthellae (algae) make oxygen and make food for the polyp from photosynthesis. They give coral its colour. </li></ul></ul><ul><ul><li>Coral polyps protect the zooxanthellae, release CO 2 , and provide it with necessary nutrients from their own waste. They build up the reef by producing limestone in their skeleton. </li></ul></ul>
  4. 9. How Valuable Are Coral Reefs? Ecosystem goods (things that can be sold) and services (things that do a job) can be measured to show how valuable coral reefs are and help highlight why they should be protected.
  5. 10. Reefs are disappearing fast <ul><li>11 % of world’s coral reefs had been lost by 2000 </li></ul><ul><li>6% are in excellent condition </li></ul><ul><li>24% are in good condition, </li></ul><ul><li>70% are in poor to fair condition </li></ul><ul><li>32 % reefs are in a critical stage or threatened </li></ul>1995 2005 32% 24% 11% 70% 6%
  6. 11. Reefs are disappearing fast <ul><li>11 % of world’s coral reefs had been lost by 2000 </li></ul><ul><li>6% are in excellent condition </li></ul><ul><li>24% are in good condition, </li></ul><ul><li>70% are in poor to fair condition </li></ul><ul><li>32 % reefs are in a critical stage or threatened </li></ul>1995 2005

  15. 21. <ul><li>Causes of Coral Reef Degradation in Cebu </li></ul><ul><li>Poverty </li></ul><ul><li>Overfishing </li></ul><ul><li>Blast fishing </li></ul><ul><li>Cyanide fishing </li></ul><ul><li>Tourism resort growth </li></ul><ul><li>Pollution from farming </li></ul><ul><li>Aquarium trade </li></ul>
  16. 22. <ul><li>Effects of Coral reef degradation in Cebu </li></ul><ul><li>Over 70% of reefs already dead </li></ul><ul><li>Coral species declining- certain species cannot tolerate siltation from resort development. </li></ul><ul><li>Reef fish at critically low levels </li></ul><ul><li>Blast and cyanide fishing increasing due to low numbers of fish </li></ul>
  17. 23. Small Scale Management of A Coral Reef Ecosystem: Cebu Coral Farm, Philippines
  18. 24. <ul><li>The community-based 2 hectare coral farm is located in Cebu, Philippines. This farm was set up in 1997 with the following objectives: </li></ul><ul><li>to provide alternative livelihood for fisherfolk who engage in destructive fishing techniques </li></ul><ul><li>to increase coral biomass </li></ul><ul><li>to rehabilitate degraded reefs with low-cost technology </li></ul><ul><li>to strengthen the environmental awareness of the community </li></ul>
  19. 27. <ul><li>30 families are working in the farm. </li></ul><ul><li>Two reef sites have been improved with 6,000 farm-grown coral fragments. </li></ul><ul><li>These activities generate income for fisherfolk, maintenance of the farm and for community projects which benefit the entire village people. </li></ul><ul><li>The social impacts are excellent because the locals are abandoning destructive fishing gears (dynamite- and cyanide fishing), &quot; Yesterday we were killing undersized reef fishes to feed our families, today we grow corals and improve our reefs &quot; said Luceno Torriefel </li></ul><ul><li>Once reefs are healthy again, fisherfolk will be able to make money from fishing sustainably (only certain fish at certain times) </li></ul><ul><li>Currently, the coral farm has 266 Coral Nursery Units (CNU's) containing approx. 22,000 fragments ready for deployment. Export of farm-grown corals could be a further option for additional income of the fisherfolk and could even pay for reef rehabilitation in the Philippines, but the national laws ban any kind of coral trade. </li></ul>
  20. 28. Sustainability <ul><li>Meeting the needs of today without messing up the needs of tomorrow </li></ul><ul><li>Why is this project sustainable? </li></ul>
