Showing results for: Waste and resource use
Food waste is common in both developing and developed countries. Estimates of the scale of waste and loss are between 30% to 40% of all food produced. Waste loss occurs during production, distribution and at the consumer stage. In richer nations, more food is wasted at the consumer level than in poorer countries: in Europe, an average of 95 kg of food is thrown out by each consumer each year. In developing countries much produce is lost due to a lack of suitable packaging and storage facilities (so called post-harvest losses). According to the FAO, consumers in rich countries waste almost as much food (222 million tonnes) a year as the entire net food production of sub-Saharan Africa (230 million tonnes). Food waste also represents a waste of all the embedded resources involved in producing it (land, water, fossil fuel inputs, agro chemicals) and in this sense is also a source of 'unnecessary' GHG emissions.
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 paper reviews the literature on the supply chain of phosphorus, a nutrient required in agriculture, and finds that current reporting is inadequate regarding phosphorus reserves and resources, losses along the supply chain, environmental and sociopolitical externalities, and open access to data.
FCRN member Peter Alexander has co-authored this paper, which finds that incremental improvements in several areas of the food system (including production efficiency, reducing food waste and changing diets) could reduce agricultural land use by between 21% and 37%, depending on adoption rates.
Conservation NGO WWF has released the 40-minute film “Our planet, our business”, which sets out five principles for businesses to follow in order to protect nature and their own future.
Over 100 food organisations, including many supermarkets, have signed the “Step up to the Plate” pledge (organised by the UK’s Department for Environment, Food and Rural Affairs) to halve food waste by 2030, support a week of action in November 2019, empower citizens and change their individual habits so as to reduce food waste.
According to this paper, households in the Netherlands wasted 41kg of solid food per person in 2016 - a 15% decline since 2010. Furthermore, 57 litres per person of potable liquids such as coffee, tea and milk are disposed of via the sink or toilet each year. Rice, bread, pasta, vegetables and pastries are among the food types most likely to be wasted (as a percentage of purchased quantity).
Wageningen University and Research has formed a consortium together with several private companies to research the use of co-products and residues from the food sector and industry as animal feed. A particular research focus will be on increasing Europe’s self-sufficiency in feed materials.
This paper calculates the environmental impacts (climate change, acidification, eutrophication, land use, and water use) caused by either making a meal by using a meal kit (which contains pre-portioned ingredients for cooking a meal) or by buying the ingredients from a grocery store.
Free-range eggs in the Agbogbloshie slum in Ghana are contaminated with some of the highest levels ever measured (in eggs) of certain toxic substances due to the illegal dumping of electronic waste from Europe, according to this report from Swedish non-profit IPEN and US non-profit Basel Action Network.
This paper maps the potential for different subnational, national, or regional areas to reduce their agricultural dependence on imported phosphorus fertiliser by recycling manure or urban waste (including both human excreta and household and industrial wastes).
This policy briefing from EU food waste research project REFRESH outlines policy options for reducing food waste at the consumer level, based on both desktop research and a survey of households in four countries.
This paper traces mass, energy flows and emissions in the beef, poultry and pork supply chains in Germany (including all emissions from the animal production stages, and emissions from energy use at subsequent stages). It outlines the potential of different strategies to reduce consumption-based emissions. It finds that the greatest emissions reductions could come from dietary change, i.e. replacing some meat consumption with consumption of soybeans and nuts, or replacing some meat consumption with offal consumption.
This policy briefing from EU food waste research project REFRESH outlines how ‘Voluntary Agreements’ between stakeholders throughout the supply chain can be used to reduce food waste, and makes policy suggestions to favour the creation of such agreements.
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.
This paper provides an assessment of the environmental impacts of converting waste streams from the food industry into products such as fertiliser, pet food, livestock feed or feed additives using the larvae of Hermetia illucens, the black soldier fly.
In this paper, FCRN members Christian Reynolds and Tom Quested review the effectiveness of different consumption-stage measures to reduce food waste. Examples of successful interventions include serving food on smaller plates (which can reduce food waste by up to 57%) and changing school nutritional guidelines (which reduced waste of vegetables by 28% because fewer students selected vegetables and those who did select vegetables ate more of them).
