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.
A wireless soil probe that measures soil conditions every 15 minutes could help farmers to apply fertilisers more efficiently and prevent overwatering. Each probe has 23 sensors and sends data to a software interface that summarises the information for farmers. Factors measured include levels of nitrogen, phosphorus, potassium, pH, moisture, temperature and aeration.
Since 2016, French grocery stores have been banned from throwing away edible food. This story examines the effects of the new law. For example, donations to food banks have increased in quantity and quality.
This book, edited by Charis Michel Galanakis, describes the latest research on how food production and processing can become more sustainable.
A report from food waste charity Feedback investigates what role supermarkets play in the production of food waste on UK farms.
This report, edited by the World Bank, reviews the literature to explore the sources and impacts of agricultural pollution in East Asia and propose solutions.
Food retailer Aldi has joined the Champions 12.3 coalition, a multi-stakeholder group aiming to achieve the Sustainable Development Goal of ‘halving per capita global food waste at the retail and consumer levels’ by 2030.
A report by the social enterprise Circle Economy finds that today’s economy is only 9.1% circular, based on their newly launched Global Circularity Metric. To move away from the current linear economic model, the report recommends extracting fewer resources, wasting less, optimising the resources we already have and cycling more resources back into the economy.
The Financial Times explores several emerging trends in the global food industry, including eating insects, new retail models in China, sugar taxes, food waste monitoring and genetically modified crops and animals.
This article examines global overuse of freshwater resources and how more sustainable irrigation practices could impact other environmental and developmental targets in the SDGs. It finds that the main likely effects are 1) increased food prices due to lower productivity and/or production costs as water prices increase, and 2) cropland expansion and associated extra GHG emissions of 0.87 gigatonnes of carbon.
Targetting the food-energy-water nexus, this review by FCRN members Eugene Mohareb and Martin Heller and colleagues summarises the energy implications of various types of urban agriculture. The goal of their research is to identify resource efficiency opportunities while increasing urban food production.
This new book, edited by Laura M. Pereira, Caitlin A. McElroy, Alexandra Littaye and Alexandra M. Girard, presents a diversity of collaborations between various governance actors in the management of the Food-Energy-Water (FEW) nexus and analyses the ability of emergent governance structures to cope with the complexity of future challenges across FEW systems worldwide.
The Food and Agriculture Organization of the UN (FAO) has published a report titled, ‘Regional Overview of Food Security and Nutrition,’ focused on Asia and the Pacific. Key messages from the report highlight that the fight against hunger is slowing, but malnutrition and stunting among children below the age of five remains high.
Researchers at the Johns Hopkins Center for a Livable Future (CLF) have developed an Excel spreadsheet that can assist in calculating the nutrient value of food that is wasted.
This paper describes an online choice experiment to understand consumer preferences around best-before dates, appearance, and packaging of food products; the paper specifically studies the demand for discounted ‘suboptimal’ products in the supermarket, and consumers’ willingness to use them in the home.
