  • Objectives of the report

    Examine reasons for inadequacy of the

    conventional poverty line (PL)

    Provide analytical inputs to ongoing

    discussions of identifying extreme poor

  • Three reasons for inadequacy of the $1.25 PL

    Consumption basket not specific to Asias poor

    Vulnerability to shocks not factored in

    Food prices rise faster than general price level

    New count of extreme poor

    7

  • Food is more costly in Asia

  • Policy implications: food price increases

    Availability

    Affordability

    Supply stability

    23

  • Policy implications: vulnerability

    Disaster risk reduction

    Climate change mitigation and adaptation

    Diversification of income sources

    Social assistance and protection

    Market-based instruments (e.g., disaster

    insurance, health insurance, crop insurance)

    24

  • Key messages

    Taking into account these factors, the

    headcount of extremely poor is substantially

    higher than by conventional measures

    Addressing vulnerability and food affordability

    and reliability are important parts of anti-

    poverty strategies
