The G20 is the world's leading forum that discusses aspects of global economic governance with the ability to influence the international agenda. The G20 nations combined represent about 80% of the global economy, two thirds of the world's population and include: South Africa, Germany, Saudi Arabia, Argentina, Australia, Brazil, Canada, China, South Korea, United States, France, India, Indonesia, Italy, Japan, Mexico, United Kingdom, Russia, Turkey, African Union (newly admitted) and the European Union.

The presidency of Brazil at the G20 in 2024 brings forth priority issues for the current Brazilian government, with the theme "Building a just world and a sustainable planet" including the fight against hunger, poverty and inequality; the three dimensions of sustainable development (i.e. economic, social and environmental dimensions); and the reform of global governance.

The MACS-G20 (Meeting of Agricultural Chief Scientists) event is the annual meeting of the top executives of G20 countries' agricultural research organizations under their respective ministries of Agriculture or similar bodies, for high-level discussions focused on research and development in the field of agriculture, in order to give global visibility to food security issues and promote joint actions internationally.

Therefore, the event is not open to the general public.

Considering that the member country that holds the annual rotating presidency of the G20 is Brazil this year, and as determined by the Brazilian Ministry of Agriculture and Livestock (Mapa), Embrapa is the main coordinator/organizer of the 2024 MACS-G20 event, with the support and guidance of Mapa and the Brazilian Ministry of Foreign Affairs (MRE).
