The report “Transformation is feasible - How to achieve the Sustainable Development Goals within Planetary Boundaries”, produced by the Stockholm Resilience Centre, identifies five measures to reach the most Sustainable Development Goals within the planetary boundaries.
The Food and Agriculture Organisation of the United Nations has published guidelines for the assessment of nutrient flows and their associated environmental impacts in livestock supply chains. The guidelines are aimed at people and organisations who already have a good working knowledge of life cycle assessment of livestock systems, and are intended to promote consistency through defining calculation methods and data requirements.
Relatively intensive, high-yield farming systems often have lower environmental impacts per unit of product, according to a new paper. The paper used a new framework to measure both land use and major environmental externalities (greenhouse gas emissions, water use, and nitrogen, phosphorus and soil losses) for several different farming systems.
This book, edited by Subramanian Senthilkannan Muthu, examines the development and implementation of a variety of indicators of sustainability for the food system.
Researchers from the University of Oxford’s Environmental Change Institute (of which the FCRN is part) have created a new tool - the “temperature of equivalence” - to map the impacts of varying degrees of climate change in different areas. They find that people living in low-income countries will, on average, experience heat extremes at 1.5°C of (global average) warming that people living high-income countries will not encounter until 3°C. This result is based on combining a map of predicted heat extremes with information on where people actually live within these areas. The paper also finds that, on average, people in high-income countries would experience the same increase in extreme rainfall after 1.0°C of warming that people in low-income countries would experience at 1.5°C of warming.
TEEBAgriFood, part of the UN Environment initiative The Economics of Ecosystems and Biodiversity, has released a report on the environmental, health and social costs and benefits of the agriculture and food system. It finds that the food system does not keep everyone healthy or protect the environment. It calls for a reform in how we measure food system performance, because relying on yield per hectare and market prices neglects other costs such as food-borne disease and environmental degradation.
FCRN member Elinor Hallström of the Research Institute of Sweden has authored a systematic review paper on how dietary quality scores are used in environmental sustainability assessment of food. The paper identifies two broad types of dietary quality scores and four different approaches to integrating nutritional and environmental assessments. It finds that both the type of dietary quality score and the way it is combined with environmental assessments can make a difference to which foods appear more sustainable.
FCRN member Ramy Salemdeeb of Ricardo Energy & Environment used Life Cycle Assessment to calculate 14 different categories of environmental impacts of three food waste management options: incineration, composting and anaerobic digestion. Composting had the lowest impacts in 7 out of the 14 impact categories.
A report from the WWF examines the environmental impacts, including carbon footprint, associated with four classic British dishes, and identifies twenty risks that climate change poses to the production of these dishes.
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.
The rising popularity of non-dairy milks has prompted calls from the dairy industry for the name “milk” to be restricted to the dairy version.
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.
The planetary boundaries concept provides a theoretical upper limit on human activity which the planet is able to sustain without major perturbation to the current ‘Earth system’. Previously, nine planetary boundaries (PBs) have been proposed and recently Steffen et al. (2015) have updated these boundary definitions and assessed the current state of the position of human activity with respect to each boundary. In this article, researchers from a number of food, climate change, agricultural and environmental research institutions around the world build on this work by assessing the impact of agriculture on each PB status, based on a detailed literature review of the available research.
