The Prime Minister of Britain, Rishi Sunak, has started a meeting about making sure everyone has enough food all over the world.
The conference is a collaboration between Britain, Somalia, and the United Arab Emirates (UAE), along with groups like the Bill and Melinda Gates Foundation.
People from over 20 countries are coming.
Mr Sunak said there will be a new online center where British scientists can connect with global research about crops that can survive in changing climates.
As the summit started, the UN asked donors to quickly give more help and support long-term solutions to fix the main reasons for hunger.
