This report from the UK charity Waste and Resources Action Programme (WRAP) provides the latest estimates for food losses and food waste in primary production (i.e. on farms) in the UK. It finds that 3% of food harvested is wasted at the farm stage (sent to waste treatment such as composting without first being used for another purpose, or left in the field) and 4% is surplus (material intended for food uses that ends up being redistributed to people, fed to animals or used for other purposes), making a total of 7%.

This report from the Food and Land Use Coalition proposes ten critical transitions that could enable the food system to provide healthy diets for nine billion people by 2050 while also protecting the climate and biodiversity. The transitions are estimated to provide over 15 times more social benefit than their investment cost, which is likely to be less than 0.5% of global GDP.

This paper quantifies the carbon emissions, water use and land use associated with the consumption of food excess to requirements, on the basis that overnutrition has sometimes been classified as a form of food waste. It finds high geographical variation in the environmental impacts of so-called excess food consumption, with impacts being an order of magnitude greater in Europe, North America and Oceania than in sub-Saharan Africa.

This blog post in Foodprint (part of US food advocacy group GRACE Communications) explores how food safety scares and recalls can cause food waste. In addition to the disposal of contaminated food items, other items of the same type are often disposed of to be sure of removing all affected items. New supply chain traceability technologies could reduce the amount of food disposed of during recalls.
