Dr. Sonesson (SIK) explains the findings of the study on global food losses.
Overview of the key findings:
Roughly one third of the food produced in the world for human consumption every year — approximately 1.3 billion tonnes — gets lost or wasted.
Every year, consumers in rich countries waste almost as much food (222 million tonnes) as the entire net food production of sub-Saharan Africa (230 million tonnes).
The amount of food lost or wasted every year is equivalent to more than half of the world's annual cereals crop (2.3 billion tonnes in 2009/2010).
Food loss and waste also amount to a major squandering of resources, including water, land, energy, labour and capital and needlessly produce greenhouse gas emissions, contributing to global warming and climate change.
In developing countries food waste and losses occur mainly at early stages of the food value chain and can be traced back to financial, managerial and technical constraints in harvesting techniques as well as storage –and cooling facilities. Thus, a strengthening of the supply chain through the support farmers and investments in infrastructure, transportation, as well as in an expansion of the food –and packaging industry could help to reduce the amount of food loss and waste.
In medium- and high-income countries food is wasted and lost mainly at later stages in the supply chain. Differing from the situation in developing countries, the behaviour of consumers plays a huge part in industrialized countries. Moreover, the study identified a lacking coordination between actors in the supply chain as a contributing factor. Farmer-buyer agreements can be helpful to increase the level of coordination. Additionally, raising awareness among industries, retailers and consumers as well as finding beneficial use for save food that is presently thrown away are useful measures to decrease the amount of losses and waste.
