Food security exists when all people, at all times, have physical and economic access to sufficient, safe, and nutritious food to meet their dietary needs. Despite significant progress over the past half-century, food insecurity remains a serious global challenge. The United Nations estimates that more than 700 million people experience hunger on a regular basis, the majority of whom live in sub-Saharan Africa and South Asia.
The global food system faces a dual challenge. On one hand, the world must produce enough food to meet the needs of a population expected to reach approximately ten billion by 2050. On the other, the agricultural systems currently used to produce food are themselves a major driver of environmental degradation. Agriculture is responsible for approximately a quarter of global greenhouse gas emissions and is the leading cause of biodiversity loss and freshwater depletion.
Improving food security while reducing the environmental impact of agriculture requires a transformation of the food system. This includes increasing the efficiency of crop and livestock production, reducing food loss and waste at all stages of the supply chain, shifting dietary patterns towards less resource-intensive foods, and making better use of available agricultural land. Technology has a role to play, with precision agriculture, drought-resistant crop varieties, and improved irrigation systems all offering potential gains.
Addressing food insecurity also requires attention to the economic and political dimensions of food access. In many cases, hunger is not caused by an absence of food, but by poverty, conflict, or inequality that prevents people from accessing it. Effective solutions must therefore combine improvements in agricultural productivity with policies that address income inequality, support smallholder farmers, and ensure that food distribution systems reach the most vulnerable populations.
