To be carried out by whom: Others

Details: Not specified, in this case conducted by researchers

Institutional scale of use: Regional

Details: Developed for the West-African context

Assesment to be used by which target audience: Multiple actors

Details: Can be used at two levels: local / community level in terms of vulnerability assessment and at state/national level for overall risk profile

Output: Risk map

Details: Vulnerability index and multi-hazard index map build the basis for the development of multi-risk profiles


Coverage & Methodology:

Region of origin: Europe

Developed by which sector: Science

Applied in practice: Yes

Geographic coverage in analysis: Africa

Potential geographic coverage: Worldwide

Sectors covered: Not sector specific

Details: Method tries to identify impacts across sectors according to selected risks

Method used: Index development

Description of methodology: First a composite vulnerability index is developed via information obtained with stakeholders. This index is then multiplied by a mulit-hazard index which includes combined effects of droughts and floods to form a risk index.

Risk framework used: Broad risk mapping according to different definition

Details: Risk is vulnerability of the system multiplied by the characteristics of the multi-hazards. In this study, the point of departure from the framework proposed by Kloos et al. is that exposure is only construed to mean the elements of the SES that are exposed to the multiple hazards, hence the term ‘exposure’ as used by Kloos et al. is replaced with ‘exposed elements’. This conceptualization helps to provide an avenue to deal with the debate on whether exposure should be part of vulnerability or included in the risk term

Risk components incorporated: All

Hazards and impacts considered in the assessment: Drought, Flood

Source of required data: Primary and secondary

Details: For indicators which cannot be described by household data such as green vegetation cover, soil organic matter, population density, and others, secondary data were used. While some of these secondary data came from local statistical reports, some were also retrieved from remote sensing data and spatial analysis in a Geographic Information System (GIS)

Temporal scale: Current

Participatory elements: Yes

Details: Indicators have been developed by relevant stakeholder groups

Consideration of interconnectedness and -dependencies of risks: Yes

Details: Explicit consideration of the combined effects of floods and droughts

Adressing uncertainty: No information

Scope of assessment: Identification of risks

Relevance for losses and damages:

Economic/Non-Economic losses incorporated: Both

Details: Non-economic losses (human lives) considered as well as protected areas as exposed element

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

Details: Applied for drought and flood


Recommendations for Adaptation measures included in Climate Risk Assessment: No

Applied by whom: UNU-EHS

Open access: Yes
