The document discusses Amartya Sen's concept of poverty as severe entitlement failure. It traces the evolution of how poverty has been defined, from income deprivation to basic needs deprivation to an inability to acquire basic needs due to a lack of entitlements. Famines are presented as a failure of entitlements rather than just a lack of food. Different groups have different vulnerabilities due to differences in how they acquire basic needs and different sources of entitlements. Evaluating poverty and deprivation requires looking at availability, accessibility, security and quality of goods and services from an entitlements perspective.
