Sustainable Development and Food Security

This set of flashcards covers key terms and definitions related to Sustainable Development Goal 2 and Food Security.

Food Security

Defined as when all people, at all times, have access to sufficient safe and nutritious food that meets their dietary needs for an active and healthy life.

Availability

Refers to the supply of food through production, stock levels, and trade at individual, national, or international level.

Access

Related to affordability and cost of food.

Utilization

Concerns the preparation and use of food to ensure sufficient intake of nutrients and energy, including sanitation and food preparation.

Stability

Refers to access to food over time, considering risks such as unemployment, inflation, drought, or political instability.

Subsistence Agriculture

A farming system in which farmers grow food primarily for their own consumption rather than for sale.

Green Revolution

A period where technologies resulted in significant increases in crop production, but also introduced high social, economic, and environmental costs.

Hydroponics

A method of growing plants in nutrient-rich water without soil.

Aquaculture

The farming of aquatic organisms, including fish, molluscs, and aquatic plants, in controlled environments.

GMOs (Genetically Modified Organisms)

Organisms whose genetic material has been altered using genetic engineering techniques to express desired traits.

CAFOs (Confined Animal Feeding Operations)

Large-scale livestock facilities where animals are raised in confined spaces and fed grains, leading to significant waste and environmental issues.

Sustainable Agriculture

Farming practices that meet current food needs without compromising the ability of future generations to meet their own.

Locavores

People who mainly eat foods that are produced locally, within a certain radius of where they live.

What is precipitation?

Precipitation is any form of water, liquid or solid, that falls from the atmosphere and reaches the ground.

What is condensation?

Condensation is the process by which water vapor in the air is changed into liquid water, often forming clouds.

What is collection in the water cycle?

Collection is the accumulation of water in bodies such as rivers, lakes, and oceans after precipitation.

What is the role of the sun in the water cycle?

The sun provides energy for evaporation and drives the water cycle by heating water in oceans and rivers.

What is transpiration?

Transpiration is the process through which plants release water vapor into the atmosphere from their leaves.

What is evaporation?

Evaporation is the process by which water changes from a liquid to a gas or vapor, typically from surfaces like lakes and oceans.

What is the water cycle?

The water cycle is the continuous movement of water between the Earth's surface and the atmosphere.

What are the stages of the water cycle?

The key stages of the water cycle are evaporation, condensation, precipitation, and collection.

What is infiltration?

Infiltration is the process by which water on the ground surface enters the soil.

What is runoff?

Runoff is the flow of water, from rain or melted snow, over the land surface, eventually reaching rivers or oceans.
