This paper shows that a huge amount of nutrients is wasted each day in the US food supply, and that much of this waste includes important nutrients that are currently under-consumed in the US. It is one of the first studies to calculate the nutritional value of food wasted in the US at the retail and consumer levels, shining a light on just how much protein, fibre and other important nutrients end up in the landfill in a single year.

This paper looks at how we can achieve greater food and nutrition security in a sustainable manner by reducing waste and it also analyses how losses impact overall food system efficiency.  It quantifies the food wasted throughout the food chain (10 stages) from primary production to human food consumption and also looks at the impact of livestock production on both food system biomass efficiency and feed crop losses. The paper defines wasted food energy of livestock production in terms of its poor efficiency in feed conversion ratios (ie. only some of the feed livestock consume end up as meat and dairy, with the rest loss via respiration, dung and urine).

A set of papers from the First International Conference on Global Food Security is now available online. The conference attracted 600 participants from 65 countries. All of the papers in the special issue are open access for the first year and available here.

In her first report to the UN General Assembly (UNGA) the new UN Special Rapporteur on the Right to Food, Hilal Elver, said that a human-rights based approach to food security is necessary to provide access to affordable, nutritious food for all and to eliminate hunger.  The report describes renewed political commitment as essential to advance the right to adequate food.

The following two reports deal with food waste costs and mitigation. The first report focuses on costs and introduces a methodology that allows for full-cost accounting (FCA) of the food waste footprint, including costs associated with the environmental impacts of food waste. The FCA framework incorporates market based evaluations of the direct financial costs, non-market valuation of lost ecosystem goods and services and well-being valuation to assess the social costs associated with natural resource degradation.

In this feature on Food Choices & Health, the United States Department of Agriculture and Economic Research Service (ERS) discusses food loss and food waste and points out the distinction in meaning between the two. They describe food loss as includes moisture loss and cooking shrinkage; loss from mould, pests, or inadequate climate control; and food waste.

The EU Gratitude project is aiming to reduce waste from post-harvest losses of root and tuber crops and turn unavoidable waste into something of value. It has yielded interesting findings on how waste from cassava and yams is managed in the value chains, findings which challenge the conventional idea that waste and losses in developing countries occur at the farm end of the value chain. In fact the results, presented at the mid-term review meeting, showed that in Ghana in particular waste and losses were greater at the consumer end and hence more costly- these patterns are more similar to those found in developed countries than previously believed.

This report from Global Food Security programme (GFS) entitled ‘Food waste within global food systems’ discusses how reduction of losses and waste throughout the entire food system can contribute to achieving global food security. It provides an independent assessment of the issues around food waste in developing and developed countries and suggests a number of potential future research priorities across the food supply chain.

Plantwise is an initiative, led by CABI, to improve food security and the lives of the rural poor by reducing crop losses. Plantwise has been initiated to help developing countries set up and run community based plant clinics staffed by ‘plant doctors’ that deliver free plant health advice to farmers.
