Study Notes

Food Security

  • Food security is when all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food.
  • The food must meet their dietary needs and preferences for an active and healthy life.

Causes of Food Insecurity and Threats

  • Population growth puts a strain on resources.
  • Regional food scarcity affects certain areas.
  • Subsistence agriculture can be unreliable.
  • Unsustainable production and homogeneity in the global food supply are major threats.
  • Nutritional deficiency and malnutrition are widespread problems.
  • Price setting can make food unaffordable.
  • Poverty limits access to food.
  • Land degradation reduces agricultural productivity.
  • Climate change impacts crop yields.
  • Water shortages affect irrigation and agriculture.

Impacts of Food Insecurity

  • Forced migration occurs as people search for food.
  • Livestock populations decrease.
  • Agricultural diseases spread more easily.
  • Conflict arises over scarce resources.
  • Famine leads to widespread starvation.
  • Death rates increase.

Strategies for Managing Food Security

  • Improved agricultural techniques and efficiency are essential.
  • Increase food production through intensification and extensification.
  • Reduce food waste at all stages.

  • Invest in local energy projects.
  • Diversify energy supply sources.

Waste Management

  • Common methods of waste disposal and treatment include landfill sites, incineration, storage, disposal at sea, recycling, and exporting waste.

Impacts of Waste Disposal Methods

  • Soil contamination from leaching and groundwater contamination.
  • Methane build-up poses explosion risks and contributes to greenhouse gas emissions.
  • Visual and noise pollution create unpleasant environments.
  • Spreading disease is a significant risk.
  • Release of toxic substances harms ecosystems.
  • Bioaccumulation and biomagnification occur in food chains.
  • Plastics and microplastics pollute oceans.
