The Food and Agriculture Organization (FAO) is a specialized agency of the United Nations that leads international efforts to defeat hunger and improve nutrition. Established in 1945, its primary goal is to ensure food security for all people by promoting sustainable agricultural practices and improving food production systems worldwide. FAO works with countries to develop policies and programs that enhance agricultural productivity and support rural development. It also provides technical assistance, data collection, and research to help nations address challenges such as climate change, food waste, and malnutrition, ultimately aiming to create a world free from hunger.
