Food loss and waste reduction should be seen as a means toward achieving other objectives, including improving food security and nutrition, reducing greenhouse gas emissions, lowering pressure on water and land resources and can increase productivity and economic growth. The formulation of effective policies toward food loss and waste reduction requires comprehensive information as to how much and where - both geographically and along the supply chain - various foods are lost or wasted. FAO's work on measurement and support to countries to take action to reduce food loss and waste is critical to tracking progress made by countries.
