COSMO (Coastal Zone Simulation Model)

COSMO is a decision-support model that allows coastal zone managers to evaluate potential management strategies under different scenarios, including long-term climate change. COSMO demonstrates the main steps in the preparation, analysis and evaluation of Coastal Zone Management (CZM) plans. The program is an interactive tool that allows coastal zone managers to explore the impacts of development projects and environmental and coastal protection measures. It calculates various criteria, including long term effects of climate change, reflecting the use of the coastal zone.

The user can explore a number of predefined cases as an educational tool, or specify new development scenarios and combinations of measures as a decision-making tool. A more complex version of COSMO has been developed to demonstrate some more realistic characteristics, constraints and limitations of institutional arrangements for CZM.

The program simulates day-to-day management of a coastal zone from the perspective of four organizations:

  1. The city government;
  2. The public works department;
  3. The environment department and;
  4. The private sector.

Each of these four roles takes annual decisions, within their means/budget and mandate, to further their own objectives.

Appropriate Use Useful as educational tools about relationship of adaptation to climate change in coastal zone management. Helps determine the advantages and disadvantages of adaptation alternatives, either as an educational or decision-support tool, in conjunction with other, more quantitative analyses.
Scale COSMO can be applied in site-specific case studies or at national scale.
Key Output The outcome of a range of different management options.
Key Input The user’s chosen management strategy.
Ease of Use Easy to use for educational purposes, although unsuitable for analysis of actual management plans by itself. Might be used within other frameworks, such as studies based on the UNEP Handbook Methodology.
Training Required For educational purposes it requires little training, although as a decision support tool it requires more knowledge of physical and socioeconomic characteristics of the situation.
