Food shortages in developed and developing countries differ significantly. Advanced economies ring the alarm bell when shops run out of lettuce or salami, while poor countries are struggling with a lack of basic food and hygiene products, as well as clean water. Nevertheless, given the logistics problems and economic headwinds, almost all countries will face a food crisis.

For example, Australia is experiencing a shortage of lettuce, which is why KFC Australia has been forced to put cabbage instead of lettuce in its burgers. Onions and salami disappeared from stores in Japan. Germany is facing a major beer bottle shortage. US citizens are deprived of their most delicious snack - popcorn. As for essential products, analysts note a shortage of tomatoes and potatoes. They highlight several factors that are fueling food shortages: weather conditions, the coronavirus pandemic, as well as the geopolitical crisis triggered by the conflict in Ukraine.

In March, farmers for Climate Action warned that the climate crisis put Australia’s food supply at increasing risk, especially due to global warming. "What climate change does is raise the base level risk of extreme weather events – putting further pressure, like an additional weight on the scales, on the balance of risks faced in food supply every day," the author of the report, Stephen Bartos, an expert in food resilience, said. Extreme climate conditions may considerably disrupt logistics chains if at least two of them occur at the same time, he added. "There’s greater fragility in the food supply chain than had previously been thought due to the impact of climate change," Bartos highlighted. He stated that food shortages would inevitably lead to a sharp increase in consumer prices.
