Hunger is the most dramatic manifestation of the socio-economic, political and environmental problems facing humanity. For decades, the United Nations has been trying to mobilize the support of the international community to end this problem. For example, the 2030 Agenda for Sustainable Development, adopted by the UN General Assembly in New York in 2015, set out a series of measurable international development goals (the Sustainable Development Goals, SDGs), including the ambitious and necessary goal of ending hunger in the world by 2030.
However, the development of the hunger problem is not encouraging. Although the number of undernourished people fell in the first few years of the 21st century, it slowly began to rise in 2015. According to estimates by the Food and Agriculture Organization of the United Nations (FAO), around 690 million people will suffer from hunger in 2020 (8.9% of the world's population), an increase of around 60 million since 2015. This means that humanity is on the way back to SDG 2 "Zero Hunger". According to FAO estimates, the current trend means that more than 840 million people worldwide will suffer from hunger in 2030, due to the interaction of three global crises: the COVID-19 pandemic (which is particularly affecting the poorest countries and those with the lowest vaccination rates), the war in Ukraine (which has triggered an inflationary spiral on the food market) and climate change (which is particularly affecting the most vulnerable countries).
