Food systems consist of all the actors and activities involved in the production, aggregation, processing, distribution, consumption, and disposal of food products originating from agriculture, forestry, fisheries, food industries, and the economic, societal, social, and natural sectors involved.The concept described above emphasizes the scale and complexity of these systems, which involve the entire food chain and are central to human needs. However, while it is intuitive to consider food systems as essential for human life, it is less immediate to identify the interdependence between climate and food systems.
During the early months of 2023, northern Italy and various regions in Europe have been experiencing a period of severe drought since 2022. Blocking anticyclones are weather phenomena that cause lack of precipitation near the center of high pressure. The number of days that blocking anticyclones have persisted has tripled over the past 40 years in the Northern Hemisphere while the number of extreme drought-related events has tripled over the past 20 years.
Under the Paris Agreements, adopted in 2015, 195 countries adopted a common goal of keeping the rise in global temperatures below 2°C compared to pre-industrial levels. A recent report published in the journal Science estimated that half of the world's glaciers (excluding Greenland and Antarctica) will disappear by 2100, even if the 'temperature increase is limited to +1.5°C. It is estimated that at least 60 percent of the glaciers in central Europe will be lost by 2100.
