Research Project Overview
A research project at the University of Toronto, known as TOsustain (Toward Sustainable Urban and Peri-urban Agriculture for Net-zero Food Systems), is investigating how urban agriculture can enhance food access and reduce greenhouse gas (GHG) emissions in the Greater Toronto Area (GTA). Supported by a $3.9-million grant from the Sustainable Agriculture Research Initiative, the study explores urban farming's potential to create a more sustainable and resilient food system. An assistant professor involved in the project highlights that urban farming isn't intended to replace large-scale agriculture but can effectively produce substantial quantities of fruits and vegetables, providing economic benefits to urban households.
Identifying Agricultural Potential
The project’s first phase involves creating an inventory of existing and potential agricultural land in urban and peri-urban spaces across the GTA, such as smaller farms, public lands, hydro corridors, community gardens, green roofs, and vacant spaces. This will help identify areas with food-growing potential, maximizing urban farming opportunities.
Measuring Greenhouse Gas Emission Reduction
Researchers are focusing on measuring how much GHG emissions urban agricultural land can capture and store. They aim to identify sustainable farm management practices that reduce emissions and create models to estimate GHG levels from urban agriculture. By utilizing sustainable farming methods that require less intensive use of fertilizers, pesticides, and irrigation, the project can offer a pathway to mitigate climate change and enhance local food production.
Reducing Reliance on Imported Food
Urban agriculture also reduces reliance on imported food, which contributes to emissions due to transportation. By increasing local food production and crop diversity, urban farming can help make the food system more resilient, particularly during crises like the COVID-19 pandemic.
Tips for Implementing Urban Agriculture in the GTA
- To successfully implement urban agriculture in the GTA, it’s essential to:
- Utilize underused spaces like rooftops, hydro corridors, and vacant lots for community gardens.
- Support policy changes, promote green roofs, and partner with local organizations.
- Educate communities, leverage hydroponic and vertical farming technologies, and integrate urban farming into new developments.
- Establish rainwater harvesting systems and local food distribution networks to enhance sustainability.
Addressing Social and Economic Challenges
The interdisciplinary project, involving researchers and partners from various sectors, aims to ensure that urban agriculture in the GTA not only complements large-scale farming but also addresses social issues like food deserts, providing nutritious, affordable produce to underserved communities.
