Today, an estimated one-third of all the food produced in the world ends up as rubbish before it even gets to the table, according to the United Nations. And when food goes to the landfill and rots, it produces methane—a greenhouse gas even more potent than carbon dioxide. The latest report from the lntergovernmental Panel on Climate Change (IPCC) titled ‘Climate Change and Land’ estimates that loss and waste of food caused between 8 and 10% of the emissions of the gases responsible for global warming in the period 2010-2016.
In turn, problems in the future resulting from climate change — such as lower yields, higher prices, a loss of nutritional value and supply chain disruptions — will increasingly affect food security. The effects will differ by country, but the consequences will be most dramatic in the low-income countries of Africa, Asia, Latin America and the Caribbean.
The urgent need to reduce food loss and waste was underlined by the findings of the latest UN report on The State of Food Security and Nutrition in the World.
Consumers can play a major role in addressing food waste. Much of the food purchased by households is discarded because of a misunderstanding of date marking and improper storage of these household food items.
