1. Adaptation to Climate Change and Sustainable Development: A Case study of Bangladesh Dr. Saleemul Huq Director Climate Change Programme International Institute for Environment and Development, London, United Kingdom

2. Bangladesh: Climate Change and Sustainable Development Study Carried out in 2000 by Bangladeshi and international team Based on previous work done on assessing vulnerability of Bangladesh to climate change impacts Two climate change and sea level scenarios chosen for 2030 and 2050

3. Objectives of the study What are the expected climate changes? What are the consequences for Bangladesh? For what climate change-induced impacts is Bangladesh most vulnerable? How can the potential effects of climate change be factored into policy making, and what adaptation measures for Bangladesh are most feasible?

4. Sectors chosen Coastal resources Fresh Water resources Agriculture Human health Ecosystem and biodiversity

8. Adaptation Measures to Mitigate Drainage Congestion in Coastal Areas Key Impacts and MeasuresCurrent State of Implementation & Requirements for Improvement Physical adaptations Increasing infrastructure drainage capacity Some bridges and culverts are poorly designed. Water and road infrastructure lacks maintenance Tidal basinsNew concept: early results are promising Institutional Adaptations Proper O&M arrangements, including establishment of local water management Poor institutional framework. Local government needs to be involved Design criteria for drainage capacity infrastructure Poorly designed and implemented. May be ineffective in coastal zones

9. Adaptation Measures to Mitigate Salinization in Coastal Areas Key Impacts and MeasuresCurrent State of Implementation & Requirements for Improvement Physical adaptations Resuscitation of river networksCould be meaningful in short-term, especially in south-west Surface water flow from upstream e.g. by diversion or withdrawal from rivers Capital intensive, but cross-dams could prevent saline water intrusion. Process should include EIA/SIA Institutional Adaptations Operation of sluices and regulatorsPoor existing management Water saving techniquesNot applied at maximum capacity. Could pose socio-economic problems to farmers

10. Adaptation Measures to Improve Morphological Dynamics in Coastal Areas Key Impacts and MeasuresCurrent State of Implementation & Requirements for Improvement Physical adaptations Mangrove greenbeltsStarted. Needs re-evaluation and continuation Cross damsNeeds-assessment necessary for new dams. Adverse effects elsewhere. Could be expensive Institutional Adaptations Protection of mangroves and coastal wetlands Evaluation of activities needed, especially regarding maximizing social benefits Land tenure lawsEvaluation needed

11. Adaptation Measures for Disasters in Coastal Areas Key Impacts and MeasuresCurrent State of Implementation & Requirements for Improvement Physical adaptations Cyclone sheltersAlready proven. Highly socially acceptable Mangrove greenbeltsStarted. Needs evaluation Institutional Adaptations Forecasting and disseminationFlood and cyclone forecasting should be location specific Involvement of CBOs and volunteers Should continue

12.

Water and road infrastructure lacks maintenance StorageNot evaluated in terms of recharging aquifers Institutional Adaptations Guidelines to incorporate CC in long-term planning Not existing Reduction of water demandNeed better policies on extraction, paying for use, promoting efficient use

13. Adaptation Measures for Freshwater Drainage Congestion Key Risks and Adaptation Measures Current State of Implementation & Requirements for Improvement Physical adaptations Sufficient road drainage capacityPoorly designed and maintained infrastructure Controlled sedimentation and Land-fills New concepts.

14. Adaptation Measures to Morphological Dynamics for Freshwater Resources Key Risks and Adaptation Measures Current State of Implementation & Requirements for Improvement Physical adaptations River training and bank protectionPoorly done. Costly, but river bank protection is high priority Dredging of navigation channelsLimited coverage Institutional Adaptations Guidelines to incorporate CC in long-term planning Not existing Improved monitoring and forecast of changes Needs capacity enhancement

15. Adaptation Measures to Increased Freshwater Flooding Key Risks and Adaptation Measures Current State of Implementation & Requirements for Improvement Physical adaptations Elevated land as flood refuge or food shelters Practiced throughout the country Flood refuge areas e.g. Dhaka city itself Needs evaluation Institutional Adaptations Improved flood warning and forecasting Proved effective. Needs more cooperation and to be location specific Evacuation of vulnerable people and valuables Limited capacity exists. Costly, especially for the very poor

16. Adaptation Measures in Agriculture Adaptation MeasuresCurrent State of Implementation & Requirements for Improvement Physical adaptations Improved irrigation efficiencyPoor.

20. Methodological Issues Addressed Choosing climate change and sea level rise scenarios Modelling impacts of chosen climate change scenarios on droughts, floods, cyclones Identifying possible adaptations Prioritising adaptation actions

22. Key findings of the study Bangladesh faces grave socio-ecological risks if it fails to adapt to climate change Many of the risks are gradual and difficult to differentiate from background variability of climate Coastal areas of the country are specially at risk Adaptation to climate change is fundamentally linked to sustainable development efforts of the country
