Find your direction

Compare the choices that shape this path. There is no score or single right answer.

  1. Which gap in a food-security case interests you?

    A supply or market disruption
    Explore agrifood systems, trade and economics.
    A household cannot afford a healthy diet
    Explore incomes, access and public policy.

    Production and access interact, but they require different evidence.

  2. Which outcome would you want to measure?

    Diet and health
    Explore nutrition, public health and evaluation.
    Reliability of access
    Explore livelihoods, prices and early warning.

    Choose indicators that match the outcome instead of using one number for everything.

  3. Where would you like to work?

    Research and policy
    Practise explaining evidence and alternatives.
    Programme design and delivery
    Practise listening, logistics and monitoring.

    Both routes need contextual understanding and accountability.

Key people

  • Amartya SenExplained why famine analysis must examine people’s entitlements and access, not only aggregate supply.
  • Norman BorlaugContributed to crop research associated with the Green Revolution; his 1970 Nobel lecture discusses agriculture and hunger.
  • Máximo ToreroStudies markets, shocks and access to healthy diets and contributes to food-security analysis.

Timeline

Debates

  • Should a food-security strategy prioritise higher yields?Compare the case for: Reliable production can strengthen availability. With the concern: More national output does not guarantee household access.
  • Should food assistance use cash or food transfers?Compare the case for: Cash can allow choice when markets function and supplies are accessible. With the concern: A market disruption can limit what cash buys.
  • Should success be measured mainly by calories?Compare the case for: Energy adequacy is an important and measurable concern. With the concern: Calories alone miss dietary quality and other forms of malnutrition.
