Coverage & Methodology:

Region of origin: North America, Europe

Developed by which sector: Science, Development cooperation

Applied in practice: No information

Geographic coverage in analysis: Worldwide

Potential geographic coverage: Worldwide

Sectors covered: Water sector

Details: Water resource management and infrastructure, flood risk management private companies

Method used: Mixed method approach

Description of methodology: Blend of the World Bank’s so-called “decision tree methodology” (Ray and Brown 2015), the adaptive planning approaches developed in the Netherlands (e.g., Haasnoot et al. 2013) and applied in delta management (e.g., Bloemen 2015, Jeuken et al. 2014, Van Alphen 2015) and the UNESCO guidelines for Integrated Water Resources Management (IWRM; UNESCO 2009)

Risk framework used: Broad risk mapping according to different definition

Details: Climate risk is defined as a climate-induced hazard with a certain probability for impacting communities and assets exposed to the hazard. These consequences can also be decomposed into vulnerability X exposure. CRIDA quantifies the climate risks within a certain climate state (future, present) but does not evaluate the probabilities that a certain climate state will occur

Risk components incorporated: All

Hazards and impacts considered in the assessment: Drought, Flood, Extreme rainfall, Storm surge

Details: Water related climate hazards

Source of required data: Primary and secondary

Details: Data on past critical events, survey data, meteorological and streamflow data, hydrology-, river hydraulics-, and flood damage models, forecast data

Temporal scale: Forward looking

Participatory elements: Yes

Details: Stakeholder engagement through a bottom-up collaborative process

Consideration of interconnectedness and -dependencies of risks: No information

Adressing uncertainty: Yes

Details: A list of guiding principles for the determination of high analytical uncertainty is provided

Scope of assessment: Identification of risks, assessment of impacts, identification of adaptation options

Details: Effectively assessing, managing, and communicating risks to stakeholders and decision makers, including successfully avoided risks and residual risks that cannot be avoided, quantified, or isolated

Relevance for losses and damages:

Economic/Non-Economic losses incorporated: Both

Details: Including the loss of life, public safety and health

Applicability for entire risk spectrum (from extreme weather events to slow onset processes): Partly

Details: Applicable only for water and water resources related risk


Recommendations for Adaptation measures included in Climate Risk Assessment: Yes

Details: The formulation and prioritisation of adaptation measures is one of the main goals of the assessment method

Usefulness for political purposes: The methodology can help national, regional and local governments overcome challenges to their respective water resources and infrastructure. Increased resilience to water-related hazards and climate impacts can prevent disruptions to relevant social services such as education and healthcare. In addition, the collaborative process of stakeholder engagement can enhance local dialogue and thereby foster social cohesion and the acceptance of adaptation measures

Applied by whom: Water resources and flood risk managers, asset and infrastructure managers, private companies, and national, provincial, and local government planning authorities

Open access: Yes
