More than a third of the world's food goes uneaten, and many crops harvested in Africa are discarded rather than sold, according to an initiative announced Jan. 21 by the Rockefeller Foundation to cut food waste and loss by half. The seven-year, $130 million project aims to tackle food waste from crops in the fields to dinner tables in industrialized nations. Sub-Saharan Africa will receive much of the initiative's resources. In Kenya, Nigeria, and Tanzania, up to half of some crops are lost due to inefficient harvesting, storage, processing, and time to market. Enough food is grown to feed the 1.2 billion hungry or undernourished people worldwide, but a third is never eaten, according to United Nations Food and Agriculture Organization figures. The initiative, called YieldWise, aims at cutting food waste and loss in half by 2030. Last year, the administration of U.S. President Barack Obama also announced a goal of reducing food waste by 50 percent by 2030. In France, legislators have banned big supermarkets from destroying unsold but edible food. Training at mango farms in Kenya, maize farms in Tanzania, and tomato farms in Nigeria is already in the works, the New York-based philanthropic organization said, teaching farmers such skills as the use of crop-preserving technologies and strategies against crop loss.
