Mobility profiles and calendars for food security and livelihoods analysis

Social vulnerability is defined as the capacity of individuals and social groups to respond to any external stress placed on their livelihoods and wellbeing. Mobility and migrations are relevant when assessing vulnerability since the movements of a population reflect on their livelihoods, coping strategies and social safety nets. Although in general migration characterization is complex and open to controversy, changes in mobility patterns for vulnerable population groups are likely to indicate a change in livelihoods or coping strategies. These changes can also indicate that the population groups may be exposed to new shocks; hence, monitoring of changes in mobility patterns can be a powerful early warning mechanism.
