The world is facing a severe hunger crisis, due to a combination of factors: climate change, war, the economic consequences of the COVID-19 pandemic and inflation. According to the United Nations, it is estimated that about 1 in 10 people worldwide are suffering from hunger and nearly 1 in 3 people are affected by food insecurity. Zero Hunger, which consists of bringing to zero the number of people suffering from hunger and malnutrition, is one of the 17 Sustainable Development Goals (SDGs) of the United Nations. This paper aims to review how governments and non-governmental organizations at a national, regional and international level are working to address the challenges posed by the world food crisis and their ability to deliver coordinated solutions to resolve this crisis. The structure of the paper is the following: firstly, the problem of world hunger is defined and quantified, resorting to metrics used by relevant global, regional and national organizations; secondly, a human rights perspective is adopted to analyse the right to adequate food; thirdly, the causes, consequences and potential solutions to the world food crisis are evaluated. Finally, a roadmap to zero hunger is presented, gathering the contributions from governments, non-governmental organisations and research institutes.
