Climate change and urban agriculture
Urban growers are climate change champions!
We see the impacts of climate change every day:
Extreme weather Poor air quality Drought Stronger pests and plant diseases
What growing food in the city can do:
- Reduce food miles, or the amount of fossil fuels burned and carbon emitted when food travels long distances. Also reduces the need for processing, packaging and refrigeration to preserve food over long distances.
- Growing food with sustainable methods reduces the need for petroleum-based fertilizers and pesticides, and traps carbon particles in the soil. Composting organic waste reduces methane emissions from landfill sites.
- More green spaces = cooler temperatures. Green cover reduces the heat island effect that traps pollution and greenhouse gases in urban areas.
- Green rooftops = more green spaces.
- Plants absorb airborne particles, so you can breathe easier!
- More people involved = greater impact! Food engages people who might not get involved in environmental issues.
- Shift eating habits towards plant-based diets that leave a lighter environmental footprint.
Green cover can have a striking impact on temperature and air quality.
