RICCAR
NegotiationsAssessment Adaptation Mitigation
Objective: To assess the impact of climate change on freshwater
resources in the Arab Region through a consultative regional
initiative that scientifically identifies the socio-economic and
environmental vulnerability caused by climate change impacts on
water resources based on regional specificities.
Purpose: To provide a common platform for assessing, addressing
and informing response to climate change impacts on freshwater
resources in the Arab region by serving as the basis for dialogue,
priority setting and policy formulation on climate change at the
regional level.
