We are losing fifth of world food to overeating, wastage

Almost 20% of the food made available to consumers worldwide is lost through over-eatingor wastage, according to a new study . The world population consumes around 10% morefood than it needs, while almost 9% is thrown away or left to spoil, researchers said.Efforts to reduce the billions of tonnes lost could improve global food security -ensuringeveryone has access to a safe, affordable, nutritious diet -and help prevent damage to theenvironment, they said. Scientists at University of Edinburgh in the UK examined 10 keystages in the global food system -including food consumption and the growing and harvestingof crops -to quantify the extent of losses.Using data for 2011 (the most recent date for which the researchers said all required data wasavailable) collected primarily by the UN's Food and Agriculture Organisation, the team foundthat more food is lost from the system than was previously thought. Almost half of harvestedcrops -or 2.1 billion tonnes -are lost through over-consumption, consumer waste andinefficiencies in production processes, researchers said.Livestock production is the least efficient process, with losses of 78% or 840 million tonnes,the team found.Some 1.08 billion tonnes of harvested crops are used to produce 240 milliontonnes of edible animal products including meat, milk and eggs. This stage alone accounts for40% of all losses of harvested crops, researchers said. Increased demand for some foods,particularly meat and dairy products, would decrease the efficiency of the food system andcould make it difficult to feed the world's expanding population in sustainable ways, theysaid. Meeting this demand could cause environmental harm by increasing greenhouse gasemissions, depleting water supplies and causing loss of biodiversity.Encouraging people to eat fewer animal products, reduce waste and not exceed nutritionalneeds could help reverse these trends, the team said.“Until now, it was not known how overeatingimpacts the system. Not only is it harmful to health, we found that overeating is badfor the environment and impairs food security,“ Peter Alexander from Edinburgh's School ofGeoSciences said.
