Sunroot Gardens is an agricultural operation centered in the City of Roses, Cascadia. They are mostly urban, farming 16 plots around the Southeast side of Portland, Oregon.
Their general farming practices:
No chemical pesticides, herbicides, fertilizers, sprays, etc.
No genetically engineered seeds
Heirloom vegetable varieties rather than hybrids
Low irrigation usage (and in some cases, none)
Bicycle-based; over 90% car-free
Cruelty-free soil amendments (i.e., no factory-farmed manure)
The project intersects with recent public debate in Copenhagen about air pollution in the city. In collaboration with Senior Scientist Jørgen Brandt from The National Environmental Research Institute in Denmark a first prototype is developed for making an indicator that can be placed in the city and display local levels of pollution as well as pollution forecasts on individual streets. The project holds an open source script for displaying data from the Internet in a variety of forms.
