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, including the variability of climate change impacts that may occur in different regions and 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.

Climate Literacy
About Teaching Climate Literacy

Reducing human vulnerability to the impacts of climate change depends not only upon our ability to understand climate science, but also upon our ability to integrate that knowledge into human society. Decisions that involve Earth’s climate must be made with an understanding of the complex inter-connections among the physical and biological components of the Earth system as well as the consequences of such decisions on social, economic, and cultural systems.
About Teaching the Guiding Principle
Other materials addressing GPb
Ecosystems on land and in the ocean have been and will continue to be disturbed by climate change. Animals, plants, bacteria, and viruses will migrate to new areas with favorable climate conditions. Infectious diseases and certain species will be able to invade areas that they did not previously inhabit.
About Teaching Principle 7
Other materials addressing 7e
Human health and mortality rates will be affected to different degrees in specific regions of the world as a result of climate change. Although cold-related deaths are predicted to decrease, other risks are predicted to rise. The incidence and geographical range of climate-sensitive infectious diseases—such as malaria, dengue fever, and tick-borne diseases—will increase. Drought-reduced crop yields, degraded air and water quality, and increased hazards in coastal and low-lying areas will contribute to unhealthy conditions, particularly for the most vulnerable populations.

Teaching Tips | Science | Pedagogy | Technical Details

Teaching Tips

  • High school science standards such as photosynthesis are covered.
  • May supplement lessons about the carbon cycle and food web.
  • 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.
  • Passed initial science review - expert science review pending.

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.
