Sensors warning of water-shortages

  1. Sustainability Problem: Water shortages due to anthropogenic forces and natural variations in climate patterns.
  2. Technology: These sensors made using an ink from carbon nanotubes dissolved in an organic compound called sodium dodecyl sulfate, were created my MIT engineers. They can be printed on plant leaf pores, creating an electronic circuit warning when a water shortage may be coming thus alerting farmers that their crops are in danger giving them time to plan solutions. Plant stomata responds to light, to carbon dioxide concentration and to drought, which can be monitored more closely for better agricultural practices.
  3. Stakeholders:
    1. Agricultural farmers
    2. Food & beverage and other industries with large agriculture supply chain
    3. Sustainable investors
    4. Developing countries concerned with drought and flooding
    5. Consumers
  4.  Implementation:
    1. Continue researching into whether detection of water stress can be earlier than 2 days. Also continue research into creating arrays of these sensors that could be used to detect light and capture images like a camera and create a database.
    2. Encourage those concerned climate change effects on agriculture, to invest and run pilot projects for these sensors.
    3. Bring this technology to market and determine where else in agriculture it can be used.
  5. Response to: JM4202
    • The mesh in the catch bag is made from recycled plastic mesh, and currently recycled HDPE ocean plastics are also being trialed in the production of the Seabins to see what content recycled material vs. virgin materials they can utilize. Creating this product with more oil absorption technology would be even more beneficial. My two questions are: What is done with the debris collected from these mesh bags and how much more efficient is this catch bag in comparison to other technologies currently on the market?
