  3. Chronic malnutrition • Types • How many? • Where?

  4. Food Security is an economic concept • Food security is “access by all people at all times to enough food for an active, healthy life.” Reutlinger et al. 1986 • {HH food consumption needs – HH food production} x Price of food ≤ Income and liquid assets available to purchase food • Global food supply and demand determine price

  5. There are economic -- in addition to humanitarian –benefits of food security • Enhanced physiological capital is a major source of economic growth (Robert Fogel) • Due to improvements in nutrition and sanitation • Thermodynamic effect: more calories mean more workers, and more intense effort • Physiological effect: more efficient conversion of energy into work output
