In an era marked by unprecedented challenges, the current global agrifood systems, faced with mounting pressures, require a paradigm shift. Population growth, environmental degradation, and socio-economic inequities, coupled with the rising impact of climate change and resource depletion, have uncovered the unsustainable nature of conventional agricultural practices based on intensive agrochemical use. As the world navigates these complexities, agroecology emerges as a transformative and holistic approach to rethinking food systems. This article delves into the limitations of current systems, the promise of agroecology, and its growing recognition globally and implementation in different parts of the world. It presents three concrete initiatives supported by FAO to advance agroecology through policy dialogue and advocacy at different levels (practitioners, legislative bodies, executive bodies).
