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.


Getting started


David Suzuki Foundation has practical tips on reducing your impact.

Live Green Toronto - programs for Toronto residents including local food promotion and a Live Green card that gets you discounts and offers for local green businesses.

Toronto Vegetarian Association makes the argument that what you eat matters more than how far it has traveled. Scroll down their page for a breakdown of energy consumption for each calorie of food.

Watch this short and fact-filled video from the Climate Change Urban Food Initiative that explains why action is needed now to ensure urban populations can access sufficient, sustainably produced, affordable, safe and nutritious food in a changing climate.

The Climate Change Urban Food Initiative web page also has webinars and a policy paper explaining the relationship between food systems and climate change.

The EAT-Lancet Commission brought together 30 scientists to define a healthy and sustainable diet. Their web page offers recommendations in a variety of formats.
