  3. 3. Overview 3When ecological integrity is not maintained, human well- being will be negatively affected. - Millennium Assessment Report (2005)Photos: Municipality of InfantaEcosystem degradation puts vulnerable communities at risk by reducing the resilience of natural systems and human societies against the impacts of climate change and increased risks of disaster. Kyoto University International Environment and Disaster Management Graduate School of Global Environmental Studies
  4. 4. Research Objectives 4 The study seeks to establish that ecosystem-based adaptation can enhance climate resilience.Research Objectives:1. Ecosystem Resilience Analysis - to assess the resilience of the mountain, river, urban, agricultural plain, estuarine and coastal ecosystems of Infanta2. Community Values for Ecosystems - to identify community values for ecosystems and their services - to determine autonomous and recommended adaptation actions3. Ecosystem-based Adaptation Plan - to develop an ecosystem-based adaptation plan for Infanta - to examine local institutions and governance systems Kyoto University International Environment and Disaster Management Graduate School of Global Environmental Studies

  13. 13. Discussion 13 Variations among the resilience of ecosystems require a different approach to adaptation - specific dimensions that need to be improved may be prioritized more that the others - dimensions may need to be addressed collectively In general, economic and ecological resilience need to be enhanced in Infanta Kyoto University International Environment and Disaster Management Graduate School of Global Environmental Studies
  14. 14. Implications to Ecosystem-based Adaptation Planning 14 A baseline is determined where adaptation measures that represent the communities responses to the specific character of the ecosystem and the physical, economic, social and institutional driving forces can be based upon; Entry points are established for an ecosystem-based adaptation strategy which can enhance climate resilience in Infanta.

  15. 15. Limitations of the Study 15-Survey results are based on perceptions of a selectgroup, which could not be verified objectively.-By assuming the established classification of ecosystemsby the local government, the survey sample per ecosystemmay not give a desired statistically valid result.-It would have been ideal to pursue the study at a river basinspace (i.e. Agos River Basin) to observe ecosystem flowsbut different institutional, jurisdictional and administrativesettings existing in its boundaries make this scale ofanalysis in Infanta and its surrounding regions difficult. Kyoto University International Environment and Disaster Management Graduate School of Global Environmental Studies
  16. 16. Scope for Further Research 16-Consideration of the broader ecosystem (i.e. Agos RiverBasin) and identify the conditions and structures withinwhich the system functions,-Utilization of science-based tools to supplement the resultsof this research,-Analysis on how ecosystem-based approaches can beintegrated into policy and governance Kyoto University International Environment and Disaster Management Graduate School of Global Environmental Studies
