• Vulnerability is…
– General attribute of system and particular instance of exposure
• Instantiation of a class
– Dynamic, a process
• Emergence, resilience
– Multi-level, occurring simultaneously at different spatial scales
• Glocal
Political ecology of vulnerable food systems
• Vulnerability emerges from the interactions of actors
• Boundaries of assessment are determined by character of network
• Coupled socio-ecological systems are complex
• Elements need to be understood in their context
Actor Network Theory
Early warning systems
Disasters
…
• Identify the actors
– Motivations, constitution, regulation
– Range of adaptive strategies and options
– Capacities and constraints
– Social networks and institutions
• Participatory, mental mapping of problem space
• Chapati exercise
Stakeholder analysis
& engagement
• Priority complexes of vulnerability and hazards
– Multiple stresses
– Links to driving forces of vulnerability
– Focus on reasons for concern: the priority outcomes of vulnerability
– Gaps in knowledge
• Sensitivity matrix
• Links to climate scenarios and socio-economic scenarios

• Range of choice and potential effectiveness
– Options
– Strategic planning
– Adaptive capacity
• Matrix inventory and checklist
• Multi-criteria assessment
• Decision support
Adaptation evaluation
• Participatory evaluation of alternative futures
• Vulnerability profiles
• Risk assessment
• Participatory policy exercises; role playing
• Knowledge elicitation and multi-agent modelling
Integrated analysis
• Objectives
– Present core methodology for grounded vulnerability assessment
– Build on your expertise and confidence in conducting V&A studies
– Demonstrate facilitation techniques
• Process
– Brainstorm on livelihoods
– Groups on livelihood sensitivity
– Report back
– Groups on socio-economic scenarios
– Report back
– Lunch and evaluation
– Further methods
– Wrap up

•Sub stages involved in the process
•Knowledge elicitation can be a big bottleneck in the research process
•KnETs are tools which can automate parts of this process
Stage 1
Fieldwork
(interviews, focus groups, etc.)
Stage 2
Interactive questionnaire design informed by
Stage 1
Identification of salient domains, drivers and strategy choices
Stage 3
Machine learning algorithm creates heuristics using data from the questionnaire
Choices made by stakeholders are recorded
Stage 4
Knowledge
Representation decision trees/rules
Learning Decision
Tree program expands/prunes/ refines existing decision trees
Testing with stakeholder input
•Interactive questionnaire
•Identify salient aspects of knowledge domain
Java
•Rule induction algorithm creates rules based on data from questionnaire
•Stakeholders participate in pruning and refining resulting decision trees using a ‘learning’ program

• Expert-stakeholder teams need a common framing and language of narratives
• Vulnerable food systems are complex: choosing the priority risks in actor networks is essential
• The end-to-end analysis should guide selection of methodology at each stage: often simple methods are powerful
