2. Key questions addressed in the BP
1. What is WS?
• dimensions
• definition
2. How does WS relate to IWRM?
3. How to make WS operational?
3. Dimensions of WS
• Literature lists many dimensions, depending on
(narrow) disciplinary framing
• Main elements
• Ensuring availability of adequate and reliable water resources
• Mitigating water-related risks (floods, droughts, etc.)
• Avoiding conflicts
• Dimensions
• Economic
• Social
• Environmental
3
4. Definition of WS
• Most common definition used (Grey and Sadoff – 2007)
“The availability of an acceptable quantity and quality of water for health,
livelihoods, ecosystems and production, coupled with an acceptable level
of water related risks to people”
• UN definition (UN-Water Analytical Brief - 2013)
“The capacity of a population to safeguard sustainable access to adequate
quantities of acceptable quality water for sustaining livelihoods, human
well-being, and socio-economic development, for ensuring protection
against water-borne pollution and water-related disasters, and for
preserving ecosystems in a climate of peace and political stability”
• Decision of TEC was not to come with a new/own definition

5. IWRM and WS
• Water Security and IWRM are symbiotic
– IWRM focuses on process / governance
– Water Security specifies what we aim to achieve

6. Quantifying WS
• Why?
• Full WS can never be achieved
• But we can increase WS
• How much? – quantification needed
• Two approaches
• Developmental approach
• Risk-based approach
6
7. • Applied at country level for
ADB countries
• some pilot applications at river
basin scale
• For GWP also applied to
selected countries in other
regions

Example of
Development approach:
AWDO 2013
8. Building blocks for quantifying WS
• Inspired by approach AWDO 2013
• Users are given the freedom to adapt the
framework to their specific needs
• Elements:
• Vision / goals
• Key Dimensions (KDs)
• Indicators
• taking IWRM criteria (3 E’s) into account

9. Water Security
Framework
• Key dimensions
• IWRM criteria
-economic efficiency
-social equity
-environ. sustainability

13. Main messages of this BP
1. What is WS?
• Multiple dimensions to be considered together
• Working definition of WS is provided
2. How does WS relate to IWRM?
• IWRM process can increase WS
3. How to make WS operational?
• Choose developmental or risk-based approach
• Determine scale and purpose of analysis
• Choose appropriate key dimensions & indicators
