תקציר	Poverty Dynamics Analysis uses household panel data to study how poverty changes over time for the same people, distinguishing those who are persistently poor from those who move in and out of poverty. Building on the work of Jyotsna Jalan and Martin Ravallion (1998) and the comparative synthesis of Bob Baulch and John Hoddinott (2000), it reframes poverty from a static headcount into a study of entries, exits, and spells. Its central output is a separation of total poverty into a chronic component, attributable to persistently low living standards, and a transient component, attributable to fluctuations around the poverty line over time.	Livelihood Vulnerability Assessment is a framework for measuring how exposed and susceptible households and communities are to climatic and socio-economic stresses, and how able they are to cope and adapt. Drawing on the IPCC's conceptualisation of vulnerability as a function of exposure, sensitivity, and adaptive capacity and operationalised in composite tools such as Hahn and colleagues' Livelihood Vulnerability Index, it translates the social and environmental dimensions of risk into indicators that can be compared across places and groups to guide adaptation and poverty-reduction investment.
