Across the world, up to 811 million people do not have enough food. According to recent estimates, 45 million people in 43 countries are at risk of sliding into famine – the most extreme form of hunger, which can result in death from starvation or disease. Indeed, parts of Yemen, South Sudan and Madagascar may be close to or are already in the grip of famine. The consequence of diets poor in vitamins, minerals and other nutrients are affecting the health and life prospects of millions more, and casting a shadow over the future of communities and entire countries. Although enough food is produced to feed everyone on this planet, the goal of a world with zero hunger, as set out in the 2030 Agenda for Sustainable Development and specifically in Sustainable Development Goal 2, remains hugely challenging due to a toxic cocktail of conflict, climate change, disasters and structural poverty and inequality. Over the past year, the socio-economic consequences of the COVID-19 pandemic have further exacerbated the situation by pushing millions of vulnerable people into greater food insecurity.
