Science in every essence is valuable for understanding environmental systems. As environmental problems of today are more erratic and large-scale, the key to go beyond the limitation of “specialized” research is through convergence of scientific knowledge. With the increasing human demand for coastal resource, it is only imperative to develop adaptive conservation and management schemes for the sustainable development of coastal environments.

CECAM adopts the integrated social-ecological approach for linking science to management. Research topics under the project for this matter are specific but not limited to the following themes:

1.Investigation of multiple environmental stress propagation to tropical coastal ecosystems based on analyses of material cycle dynamics in a land-ocean integrated zone.

  • Monitoring and analysis of terrestrial environmental loads on tropical coastal ecosystems
  • Investigation of material cycle dynamics in land-ocean integrated zone of tropical coastal ecosystems
  • Analysis of combined impacts by local and global environmental stresses on coastal ecosystems
  • Coastal ecosystem evaluation in terms of CO2 source/sink

2.Investigation of biodiversity, functions and maintenance mechanism of tropical coastal ecosystems and their response to multiple environmental stresses.

  • Investigation of biodiversity, functions and inter-connectivity of local habitats consisting of coral reefs, seagrass beds, tidal flats and mangrove forests and their responses to multiple environmental stresses
  • Investigation of impacts of episodic events like typhoon, flood and oil/coal spill on tropical coastal ecosystems and their recovery processes
  • Investigation of reef connectivity in tropical island-studded sea and environmental influences on larval dispersal and recruitment processes

3.Comprehensive assessment and prediction of multiple environmental stresses and ecosystem response based on an integrated simulation model system development.

  • Quantitative assessment of multiple environmental stresses on tropical coastal ecosystems based on the development of an “atmosphere-land-coast-ocean” coupling model for simulating physical and chemical processes
  • Analysis and prediction of dynamic response of tropical coastal ecosystems to multiple environmental stresses based on the development of a coastal ecosystem model
  • Quantitative assessment and prediction of multiple environmental impacts on reef connectivity based on the coupling model and a larval dispersal model
  • Development of numerical models to assess impacts on coastal ecosystems by episodic events like typhoon and oil/coal spill

4.Establishment of adaptation scheme for tropical coastal ecosystems under multiple environmental stresses.

  • Establishing an effective scheme to assess sources and propagation processes of environmental impacts and carrying capacity of coastal ecosystems as a basis for mitigating environmental stresses
  • Proposing an effective scheme for improving and maintaining MPA networks as a measure to enhance ecosystem resilience by identifying core habitats in local/regional reef connectivity and by assessing environmental stresses on MPA candidates
  • Damage potential mapping for coastal ecosystems based on multiple environmental stress assessment and prediction
  • Establishment and implementation of a comprehensive system for continuous monitoring of multiple environmental stresses and coastal ecosystem responses
  • Development and implementation of Integrated Decision Support System (IDSS) and capacity building for its management and effective applications
  • Socio-economic investigation of local communities as sources and solutions of environmental stresses for integrated coastal zone management
