Revolutionizing Agriculture: Remote Sensing in the Green Revolution 2.0

The Green Revolution 2.0 aims to combat hunger by enhancing agricultural productivity through advanced methods like remote sensing. This initiative focuses on cultivating high-yielding and fast-growing crops while utilizing effective irrigation and farm management techniques. It addresses sustainability challenges, including salinization and pollution, by improving crop resilience to stress and input efficiency. Remote sensing technology enables precise monitoring of agricultural investments and environmental changes, facilitating smarter decision-making in farming and ensuring sustainable food production.

  1. Green Revolution 2.0Remote Sensing Jamie Jacobsen

  2. Goal: alleviate hunger by increasing agricultural productivity per unit of land • Focus on high yielding, fast growing crops • Irrigation • Farm management First Green Revolution

  3. Sustainability: deep ground water sources • Salinization: increase of salt content in soil • Pollution: water contamination with herbicides and pesticides BUT

  4. Improve crop tolerance to stress • Increase input efficiency • Sustainability • Digital Revolution Green Revolution 2.0

  5. Remote Sensing

  6. Hot air balloons • WWI aerial photography • Cold War • Green Revolution 2.0: Target and monitor agricultural investments and developments Remote Sensing History

  7. Remote Sensing “The process [that] involves the detection and measurement of radiation of different wavelengths reflected or emitted from distant objects or materials, by which they may be identified and categorized by class/type, substance, and spatial distribution” NASA Earth Observatory

  8. Passive vs. Active Sensors Technology: EMR

  9. Visible Infrared Microwave Technology: Spectral Reflectance Signature

  10. Emission of EMR • Energy from sensor to Earth’s surface • EMR interaction with objects • Energy back to remote sensor • Sensor data output 5 Stages of Remote Sensing

  11. So… Why do I care?

  12. Remote Sensing: Green Revolution Applications

  13. Meteorology

  14. Hydrology

  15. Agriculture

  16. Natural Disasters

  17. Oceanography • Glaciology • Geodesy • Military Others

  18. Advantages: • Not necessary to be physically present. • Survey large area at one time. • Consistent, time series data shows change. • Disadvantages: • Subjective interpretation. Main Points

  19. Numerous applications • Ability to monitor change • Continued investment in future Significant!
