Food supply

Impacts of food supply scarcity

  • Famine: a severe shortage of food leads to widespread malnourishment, hunger, and death.
  • Undernutrition: long-term lack of nutrients weakens immune systems, stunts growth, and reduces productivity.
  • Soil erosion: over-farming and deforestation to grow more food degrade soil fertility, reducing future crop yields.
  • Rising prices: food shortages increase prices, making food unaffordable for the poorest.
  • Social unrest: food shortages and high prices can cause protests and riots.
