A severe heatwave and drought in Canada last July significantly diminished the mustard crop, impacting the global supply as Canada is a major exporter. The loss is expected to affect France, which relies heavily on Canadian mustard for 80% of its production. The expected compensation from Ukraine and Russia is now unlikely due to the ongoing war and sanctions. Canadian producers are shifting to other grains, further reducing mustard production. In response, France is contemplating reviving mustard cultivation and encouraging the breeding of resilient varieties to combat changed climatic conditions. A temporary shortage is anticipated until these measures bear fruit.
