Science forum Day 2 - Manjurul - Adapting to climate change

  1. 1. Policy Brief on Adapting Aquaculture to Climate Change for PoorFarming Households in Coastal Bangladesh<br />Manjurul Karim, William J Collis, Michael Phillips, Neil Andrew, Arif Azad and Golam Hossain<br />
  2. 2. National policies linked with climate change <br />Existing policies that address the issue of climate change: <br /><ul><li> National Water Policy (NWP), 1999
  3. 3. National Agriculture Policy, 1999
  4. 4. National Water Management Plan (NWMP), 2001
  5. 5. Coastal Zone Policy, 2005
  6. 6. Coastal Development Strategy, 2006
  7. 7. Draft National Disaster Management Policy, 2008</li></ul>National policies do not explicitly address climate change issues- <br /><ul><li>Bangladesh Environmental Policy, 1992
  8. 8. National Forest Policy, 1994
  9. 9. National Environmental Management Action Plan, 1995
  10. 10. National Energy Policy, 1996
  11. 11. Fisheries Policy, 1998
  12. 12. National Health Policy, 2000
  13. 13. National Land Use Policy, 2001 and
  14. 14. National Food Policy, 2006</li></li></ul><li>Projected climate change impacts<br />Sea level rise (30-80 cm increase by 2050) and increased flooding<br />Increased vulnerability to cyclone and storm surges (5-10%) increase by 2050<br />Increased salinity (soil and water) <br /><ul><li> Increased moisture stress > leading to increased draught
  15. 15. Greater temperature extremes (1.4 oC by 2050)
  16. 16. Greater monsoon precipitation (20-30% increase by 2050)</li></li></ul><li>Projected climate change impacts<br />Impacts (eg. water temperature increase by 2oC) <br />++: <br />10% increase of precipitation river runoff increase by 15% <br /> - increaseflood plain area, feeding ground and productivity <br />_ _: <br />a) destroy aquaculture infrastructure > reduce closed water production <br />b) may stimulate 300-500% incretion of growth of microphytes - <br /> - decrease water productivity <br /> - reduces fish habitat and dissolved oxygen supply <br />
  17. 17. Lessons fromWorldFish projects (CAARP, 2010)<br /> Preparedness and adaptation measures:<br /><ul><li> Rising pond dikes and setting nylon net
  18. 18. Fish nurseries, stocking of large size fingerlings, fast </li></ul> growing species<br /><ul><li> 1 million carp fingerlings (by weight 7.4 MT), value </li></ul> US$ 24,074 produced by 126 households within ~ 3.5<br /> months<br /><ul><li>Well planned harvesting and selling of fish and vegetables</li></li></ul><li>Lessons from WorldFish projects <br /><ul><li> 77% of households reinvested in aquaculture after</li></ul> the disaster<br /><ul><li> Stocking larger size fingerling brought 30% higher </li></ul> production and 36% higher profit margins within 6-<br /> 8 months (CAARP, 2010) <br /><ul><li> Fish consumption: 8 -19 kg/person/yr (~80% increase)
  19. 19. Other promising adaptive aquaculture </li></ul> technologies: nutrient dense small<br /> fish, rice-fish and cage aquaculture <br /> (Adivashi, 2009) <br />
  20. 20. Policy recommendations<br />Inclusion of aquaculture in national development planning<br />Capacity building, information accessibility and awareness raising on climate change impact prediction and adaptation<br />Promotion and adaptation of aquaculture technologies to the realities of climate change<br />Increasing focus on technological innovation towards development of sustainable Aquatic-Agricultural Systems (AAS)<br />More priority on small scale aquaculture (>10 million ponds)<br />Develop measures to mitigate the effects of climate change on livelihoods and aquaculture<br />Flexible water storage options and adaptation to climate change<br />Mobilize, develop and empowering community based organizations<br />
  21. 21. Conclusion<br /><ul><li> Adapting aquaculture to climate change ?</li></ul>Institutionalization and mainstreaming climate change adaptation interventions is needed to :<br /><ul><li>ensure medium and long-term sustainability
  22. 22. save millions of vulnerable coastal livelihoods
  23. 23. make millions of other Bangladeshi people food secure</li></li></ul><li>9<br />THANK YOU<br />
