Why 'vertical farming' is not a fix for our food system
The Canadian government launched its first National Food Security Strategy in June 2026. The strategy aims to invest $750 million to increase year-round Canadian production of fruits and vegetables, including on so-called vertical farms.
The Canadian government's investment in vertical farming as part of its National Food Security Strategy is a notable development, but it raises important questions about the potential of this technology to address the complexities of our food system. Vertical farming, which involves growing crops in vertically stacked layers, often in indoor environments, has been touted as a solution to increase food production while minimizing land use and environmental impact. However, critics argue that it may not be a silver bullet, citing high energy costs, limited crop selection, and uncertain scalability.
The emphasis on vertical farming in the National Food Security Strategy reflects a broader trend in the agricultural industry, where technology and innovation are being sought to address pressing issues such as food security, sustainability, and climate change. While vertical farming has shown promise in certain contexts, such as urban areas with limited arable land, its potential to contribute significantly to national food security is still unclear. The scientific community will be watching closely to see how the Canadian government's investment in vertical farming plays out, and whether it can help to address the country's food security challenges.
As the Canadian government moves forward with its National Food Security Strategy, it will be important to monitor the outcomes of its investment in vertical farming, and to consider the potential risks and limitations of this technology. Key areas to watch will include the energy efficiency and environmental sustainability of vertical farming operations, as well as their ability to produce a diverse range of crops at scale. Additionally, the impact of vertical farming on traditional agricultural practices and rural communities will need to be carefully considered, to ensure that this technology contributes to a more equitable and sustainable food system.
