Various health agencies recommend dietary intake of the two fatty acids omega-3 Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA) at a level between 250 and 500 mg/day.
Performing full life cycle assessment on foods and diets is a data- and resource-intensive undertaking and as a result many studies tend to adopt a simplified approach, for example by limiting the number of food studied (in the case of diets), using proxy data, or limiting the system boundaries (cradle to farm gate; cradle to retailer – ie. not the full cradle to the consumer’s mouth).
This special issue of the Journal of Industrial Ecology takes a closer look at how consumption is increasingly met by global supply chains that often involve large geographical distances.
This report discusses how less protein in food and fewer phosphorus compounds added to food products could reduce the eutrophication of the sea. Below is a summary of the research by two of the report’s authors, Anders Grimvall and Eva-Lotta Sundblad from the Swedish Institute for the Marine Environment.
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.
In this paper, researchers from James Cook University, Australia, assess the impact on the environment and agriculture of 33 planned or existing “development corridors” in sub-Saharan Africa. Development corridors are tracts of land earmarked for large-scale infrastructure expansions (e.g. road access) with the aim of increasing agricultural production.
This paper quantifies what the environmental impacts would be if the typical US diet were to shift in line with the USDA dietary recommendations. The paper has created a lot of interest and debate since it shows that shifting towards healthier diets in some cases can increase the energy, emission and water intensity of the diet. This is why we wanted to provide a more extensive summary and some commentary below. Please do read, share and add your own comments.
This FAO brief on food waste discusses the carbon footprint of global food waste and so called embedded emissions in avoidable food waste. In order to measure the avoidable emissions it is necessary to know how much of what kind of food is wasted and where.
This thesis by PhD student Esther Sanyé-Mengual (Autonomous University of Barcelona) discusses urban rooftop farming, its potential and its associated environmental impacts and economic costs.
This paper entitled Creating When You Have Less: The Impact of Resource Scarcity on Product Use Creativity, argues that resource scarcity actually translates into enhanced consumer product-use creativity.
This report by the Food and Agriculture Organisation of the United Nations (FAO) aims to inform decision-making that focuses on reducing impacts on natural capital.

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.
This paper, co-authored by FCRN member Christian Reynolds, investigates the economic and environmental efficiency of charities and NGOs that divert and redistribute wasted but edible food. Through a case study of food rescue organizations in Australia, the authors show that food rescue operations generate approximately six kilograms of food waste per tonne of food rescued, at a cost of US$222 per tonne of food rescued. This is lower than purchasing edible, non-food waste food at market-cost. Secondly, for every US dollar spent on food rescue, edible food to the value of US$5.71 (1863 calories) was rescued.
Meat and Livestock Australia (MLA) reports that the Australian beef industry has reduced its environmental footprint over the past 30 years. The results are presented in a new paper in Agricultural Systems, and in a press-release MLA writes that:
