A local greenhouse had an open day, the place was like a ZDay.
Hydroponics/Aquaponics
Hydroponics/aquaponics allow us to reduce water consumption and pesticides. It also allows us to grow crops inside cities, promoting localization. These systems may also utilize automation.
Use of natural pest control
Using nature itself allows us to minimize environmental damage, since the alternative may be pesticide.
3D printing
3D printing allows us to customize manufacturing and produce them locally, which allows localization. The development of the 3D models may also be open-source, making it possible to improve and share the designs as a community.
Drones
Using drones helps creating a digital digital_feedback loop, which allows us to monitor our usage and waste.
