  1. Mitigating greenhouse gas emissions through mangrove plantation and charcoal production Patanan Kridiborworn, Amnat Chidthaisong*, Sirintornthep Towprayoon and Sudarat Tripetchkul1 The Jointed Graduate School of Energy and Environment, and 1School of Bio-resources and Technology King Mongkut’s University of Technology Thonburi *Corresponding email: amnat_c@jgsee.kmutt.ac.th

  2. Outlines • Introduction • Research Objectives • Material & Method • Study site • Biomass measurement • Soil and plant C analysis • Charcoal production and characteristics • Calculation of CO2 reduction potential • Conclusions

  3. (Mangrove ) forest and climate change

  4. Mangrove and climate change • Ecosystem services • December 2004 Asian tsunami and Hurricane Katrina in 2005 gave the world a new appreciation for mangrove forests.  mangroves help stabilize shorelines and thus protect lives and property from such natural disasters

  5. Mangrove and climate change • Mitigation: Carbon sinks • Soil • Biomass • Renewable energy • Adaptation: Local livelihood, marine/coastal productivity, Safety

  6. Status of mangrove forest area in Thailand http://www.fao.org/docrep/007/j1533e/J1533E60.htm

  7. Loss due to land conversion http://www.northamerica.unep.net/geas/archive/Sep1-15_09.html

  8. Objectives • How mangrove plantation and utilization for charcoal production could help mitigate greenhouse gas emissions and support the adaptability of charcoal production community? Energy replacing LPG Forest with utilization and management Renewable Reduced CO2 emission Mangrove tree Charcoal

  9. Study site

  10. Location site : GIS and GPS mapping • Field surveys • Soil data: % Total C,% Total N, Bulk density • Mangrove plantation & biomass measurements • Charcoal production Study site Source: GIS Map of Samutsongkram Province, Ministry of Interior, 2008

  15. Results: Soil carbon

  16. Results: Soil carbon Increasing?

  17. Results: Charcoal production

  18. CO2 Reduction ลดการปล่อย CO2 reduction? CO จากแหล่ง 2 Burning ฟอสซิล CO2 in the atmosphere ทดแทนพลังงาน Charcoal-C Replacing fossil fuel ฟอสซิล เช่น ก๊าซ หุงต้ม Photosynthesis Charcoal production Biomass-C

  19. Results

  20. Summing up--

  21. What we have learned? • Local management and utilization of mangrove could be environmentally beneficial. • Mitigation and adaptation interlinks? • Other economic returns/analysis? • More— • Carbon leakage • Integrating into LCS • Supports & sustainability

  22. Thank you very much • for you attention!
