Overview • Structure of the
vulnerability component of the WEAP+ training workshop
• Basic concepts• Framework for vulnerability
assessment for use in WEAP
• The first of two working group exercises
Structure of Vulnerability Training Component
• Aims: to provide a methodology
for analysis of stakeholder perspectives
to indicate how vulnerability assessment links with WEAP & MCA-WEAP
• Approach: presentations and two working group exercises
Basic Concepts (1)
• Vulnerability: degree to which a system is susceptible to, or unable to cope with, adverse effects of environmental change
Basic Concepts (2)
• Vulnerability to climate change is determined by two major factors Character, magnitude and
rate of climatic variation Adaptive capacity, or
ability to cope, of system
Basic Concepts (3)• Vulnerability to climate
change of water resources focuses on: Spatial changes in
precipitation Temporal changes in
precipitation• Water stress: demand for
freshwater > 20% supply• Water scarcity: consumption
< 1,000 m3/cap-yr
Basic Concepts (4)• Vulnerability dimensions are
simply concerns for wellbeing and basic needs
• Vulnerability indicators are aspects of the vulnerability dimensions which can be quantified
Framework for Vulnerability Assessment
among Stakeholders What affects ability to cope? What are the dimensions of
vulnerability? How do vulnerability
dimensions relate to vulnerability indicators?
How is stakeholder output linked to WEAP and MCA-WEAP?
How might vulnerability change?
-Biophysical diagnostics-Socio-ecnomic diagnostics-Institutional diagnostics-Analysis of legal framework
-Analysis of extreme events-Probability of occurence-Trends-Use of climate variability to project future climates

WHERE ARE THE HAZARDS?
What affects ability to cope?
What are the dimensions of vulnerability?
• Possible examples Water: drinking water,
washing water Health: medicine, doctor,
school education Land and resources: land,
food Domestic: clothes, income
source, housing

Working Group Exercise Aim
• Simulate processing of information from stakeholder group
• Use and/or translate stakeholder information into inputs useable by WEAP and MCA-WEAP
Working Group Exercise Context
• Location: semi-arid water basin in Country N
• Current climate: low rainfall, recurrent drought
• Socioeconomic: mix of villages and small towns, income stratification
• 5 types of stakeholders: smallholders, pastoralists, traders, village council members, extension workers
Working Group Exercise Steps
• Single large group with individual discussion groups
• In individual discussion groups:•Discuss basic needs•Classify whether met or
unmet•Identify relevant climatic
hazards• In large group:
•Develop vulnerability dimensions
•Construct initial indicators
What affects ability
to cope?
