Deep dives
Impact of the Food System on Climate Change
The food system significantly contributes to climate change, accounting for approximately one-third of global greenhouse gas emissions. Factors such as agricultural practices, land use changes, and supply chain activities are responsible for these emissions, including the release of CO2, methane, and nitrous oxide. The relationship between climate change and the food system is reciprocal—changing climate patterns affect agricultural production, leading to altered growing seasons and increased pest and disease prevalence. Understanding this two-way interaction is essential for effectively addressing both food security and climate resilience.
