In this report we consider key factors contributing to the current unacceptable level of food waste across the world and the wider implications for sustainably supporting projected population growth.
With the global population estimated to reach 9.5 billion by 2075, mankind needs to ensure it has the food resources available to feed all these people. With current practices wasting up to 50% of all food produced, engineers need to act now and promote sustainable ways to reduce waste from the farm to the supermarket and to the consumer. Engineers, scientists and agriculturalists have the knowledge, tools and systems that will assist in achieving productivity increases. However, pressure will grow on finite resources of land, energy and water. Although increasing yields in hungry countries is an appropriate response to an emerging food crisis, to ensure we can sustainably meet the food needs of over three billion extra people on the planet by 2075, we call for initiatives to be taken to reduce the substantial quantity of food wasted annually around the world. The potential to provide 60-100% more food by simply eliminating losses, while simultaneously freeing up land, energy and water resources for other uses, is an opportunity that should not be ignored. Factors affecting waste relate to engineered infrastructure, economic activity, vocational training, knowledge transfer, culture and politics.
