U.S Treasury Secretary calls for urgent action to improve food security in Africa

U.S. Treasury Secretary Janet Yellen on Tuesday called for urgent action to improve long-term food security in Africa and around the world, while adapting agricultural practices and technology to the changing climate. Reuter reports that Yellen spoke after hearing from a woman beekeeper and other farmers whose work was supported by a U.S.-backed project in a rural Zambian village. Part of the broader Green Climate Fund, the project helps small-scale farmers in 155 villages in Zambia produce more food and manage the impacts of climate change.
