This dataset Covers FAO Weight percentages of food losses and waste. Data presented is obtained from the publication "Global Food Losses and Food Waste" which is based on studies carried out from August 2010 to January 2011 by The Swedish Institute for Food and Biotechnology (SIK) on request from the Food and Agriculture Organization of the United Nations (FAO). The study highlights the losses occurring along the entire food chain, and makes assessments of their magnitude. The results of the study suggest that roughly one-third of food produced for human consumption is lost or wasted globally, which amounts to about 1.3 billion tons per year. This inevitably also means that huge amounts of the resources used in food production are used in vain, and that the greenhouse gas emissions caused by production of food that gets lost or wasted are also emissions in vain. Note: estimated/assumed waste percentages for each commodity group in each step of the food supply chains (FSC) are presented.
