Science for a Hungry World: Agriculture and Climate Change
http://pmm.nasa.gov/education/videos/science-hungry-world-agriculture-and-climate-change

NASA

This NASA video explores the relationship between climate and agriculture. The video discusses the variability of climate impacts in different regions, as well as the effects of population growth and higher demands for food in areas that already struggle to supply food for the people. The video highlights the need for accurate, continuous, and accessible data and computer models from NASA satellites to track and predict the challenges farmers face as they adjust to a changing climate.

Video length: 5 min.

Teaching Tips

  • High school science standards such as photosynthesis are covered.
  • The video could be used to supplement lessons about the carbon cycle and food web.
  • The video could be used to frame discussions about global, social, and environmental justice issues.

About the Science

  • This NASA video focuses on how increased carbon dioxide from burning fossil fuels will impact agriculture around the world.
  • The video clarifies the the balance between the positive impacts of increased CO2 on plant growth and the negative impacts of a warmer atmosphere on growing seasons, water availability, drought, fire, and flooding.
  • The regions where food is grown now will not be the regions where the same crops will be able to grow in the future.
  • Comments from expert scientist:
    Scientific strengths:
    - explanation of why there are vulnerable agricultural populations
    - presentation of problem with a human population increase
    Suggestions:
    - there is not a lot of in depth information about how climate change affects crops
    - definitely would need to be used as an introduction to climate change impacts, not a stand alone activity

About the Pedagogy

  • Depending on the intended audience, it may be necessary to clarify the role of CO2 and H2O in photosynthesis, and other biogeochemical cycles, such as nitrogen and phosphorus, as limiting factors for agriculture.

Technical Details/Ease of Use

  • Easy to use. The video can be shown online or downloaded.
