RATIONALE
�There are many linkages between ecosystems and disaster risk
reduction:
o Reduction of exposure
o Reduction of vulnerability of exposed communities or
systems
o Increased resilience
o Provision of livelihoods

o Provision of livelihoods
� The above are often interlinked and we should not get bogged
down in definitions here!
� However the links between ecosystems and DRR are sometimes
not sufficiently understood

OBJECTIVES
� To take stock of the latest scientific developments on the linkages
between ecosystems and their role in DRR
� To take stock of good practices on ecosystem-based approaches for
DRR
3
� To enhance the dialogue between the scientific and practitioner
communities in order to improve knowledge and practice of
ecosystem-based approaches for DRR.

FORMAT
Four interlinked sessions:
Session 1: Introduction of concepts
Session 2: Scientific knowledge, tools and methods
Session 3: Practitioners’ based knowledge, tools and methods
Session 4: Integration of concepts
The red-line is provided by the sessions and by a set of key questions

The red-line is provided by the sessions and by a set of key questions
We will have: a few oral presentations for setting the scene; the “work” will takeplace in breakout groups and plenary sessions; posters can be discussed overcoffee breaks
The entire workshop will be supported visually through graphic facilitation
The types of hazards considered are those linked to coastal processes, as wellas landslides and wildfires

Expected Outputs
� A roster of scientists, experts and practitioners working on
ecosystems and DRR
� Roadmap for the future:
o Research agenda
