Knowledge for better food systems

Showing results for: Environmental input-output analysis

Environmental input-output analysis is used to examine the material flows and structures in production and consumption within one or several economies (which can be a company or a country). As such it provides information about the supply and use of goods and services within the economy, and their environmental consequences. It belongs to the broader concept of ‘environmental accounting’ used to identify resource use and to measure and communicate the costs of a company's or a nation’s economic impact on the environment.

No country meets basic needs for its citizens at a globally sustainable level of resource use, according to a study by researchers from the University of Leeds.

This new study by FCRN member Paul Behrens and colleagues investigates the environmental impacts of a nationally recommended diet when compared to the national average diet for 37 nations across the world, including 9 middle income nations.

This paper by FCRN member Dana Boyer examines how policy interventions at the city scale can affect three environmental outcomes of food production: greenhouse gas emissions, water use and land use. It uses India’s capital city Delhi as a case study. It sets out to assess the magnitude of city-scale food system actions as compared to certain actions which can be taken beyond the city boundary.

This review assesses the performance of organic cropping systems as an approach to sustainable agriculture, and seeks to identify the contextual considerations (such as type of cropping system) that may affect this performance. The scope of the review is constrained to the level of the farming system (i.e. excludes considerations of other components of the food system, such as packaging or transport). In order to provide an unbiased assessment of organic farming as a means of sustainable agriculture, rather than approaching the question from the usual “What does organic farming do well/badly?” angle, the authors ask “What constitutes successful sustainable agriculture?” then measure organic farming against this yardstick.

This study estimates the environmental impacts of what it terms discretionary foods - foods and drinks that do not provide nutrients that the body particularly needs. It finds that these foods account for 33-39% of food-related footprints in Australia.

This report, Food Systems and Natural Resources”developed by the International Resource Panel (IRP) looks at the use and management of natural resources that go into the food system, the consequences of that management and the options to improve the efficiency with which they are managed.

The German car giant Volkswagen has admitted that they have cheated in emissions tests in the US. Since 2009, Volkswagen has been installing elaborate software in 482,000 "clean diesel" vehicles sold in the US and according to the Environmental Protection Agency (EPA), these cars had devices in their diesel engines that could detect when they were being tested, changing the performance accordingly to improve results. The cars' pollution controls would then only work when being tested for emissions.

We all know that the food system today is undermining the environment upon which future food production depends. But while we generally agree that we need do something to make food systems more sustainable, we do not necessarily agree about what, exactly, should be done. This paper explores these questions by considering how stakeholders think about efficiency in relation to animal production and consumption, both terrestrial and aquatic. It takes as its starting point three broadly discernible views.

This analysis from The Carbon Brief provides a useful summary of the Bonn Climate Talks in late August/early September 2015. Countries are said to have made progress on some key points and started to lay out the skeleton of the planned agreement. Still however, disagreement over many details remains profound. The meeting which closed on 4th September in Bonn in Germany, was the penultimate session of United Nations talks before the Paris climate conference this December, where countries are due to adopt a new global climate change agreement.

This article reports that a new fish and animal feedstock product which uses methane gas may be released into the European feedstock markets from the beginning of 2018. The product, FeedKind, is currently in pre-production phase and it is described that the manufacturing process is very similar to the way in which Marmite and other yeast-extract sandwich spreads are produced.

This paper discusses urban farmers’ markets in relation to food accessibility, the type and variety of foods they offer and their price and quality. This US based study is the first to itemize farmers’ market products in an entire urban county—in this case the Bronx—and compare them with what is available in nearby stores. It finds that farmers’ markets located in urban areas may not contribute positively to nutrition or health.

Due to the large share of non-CO2 GHGs in emissions from livestock production, the choice of GHG metric used to compare emissions of different GHGs is crucial, both in order to assess the aggregate contribution of the livestock sector to climate change and for highlighting hot-spots in the animal food chain where emission reductions can be most cost-effectively made.

This paper investigates the environmental impact of the diets of Australian households at different income quintiles. The paper looked at 2003 household consumption and argues that income affects the environmental impacts of household diet, with higher income corresponding to higher impacts. The higher the income bracket the more was spent on food and this translated through to a higher environmental impact (GHG CO2e, water, waste, energy) at higher incomes.
