This report from FoodPrint, part of the GRACE Communications Foundation, describes the problems associated with plastic, metal and paper/fibre food packaging. It also sets out potential solutions, including reusable food containers, plastics that can be more easily recycled, compostable packaging materials, and bans on certain types of packaging (e.g. plastic straws).
This book explores different indicators that are used to assess the sustainability of food systems and how projects using these metrics can affect communities and policies.
This paper from researchers at Oxford’s Livestock, Environment and People (LEAP) project considers the health and environmental impacts of consuming an extra portion per day of 15 different foods. For many of the foods, those with beneficial health impacts also have lower environmental impacts, while many of those with greater environmental impacts also have greater disease risk.
FCRN member Ujué Fresán has co-authored this paper, which calculates the environmental impacts associated with the packaging of several breakfast foods (including orange juice, cereals and peanut butter). For each food product, significant differences in carbon footprint were found, depending on packaging size, packaging materials and brand. Packaging consistently accounted for a lower carbon footprint than production of the food item itself.
In this paper, FCRN member Nicholas Bowles of the University of Melbourne reviews existing data on the environmental impacts of the livestock sector and considers these impacts in the context of planetary boundaries. The paper reports that efficiency alone is unlikely to be adequate to shrink livestock’s impacts to a sustainable level, and that dietary shifts will also be necessary.
The 2019 Green Alliance Annual Debate discusses the ways in which earth observation and data science can improve our understanding of and ability to address environmental issues - for example, monitoring deforestation or water levels in reservoirs in real time through satellite images.
Using home-made solar cookers instead of microwaves could reduce greenhouse gas emissions and electricity use as well as enhance social well-being and motivate people to behave more sustainably, according to this paper, which considers Spain as an example.
This life cycle assessment of beef cattle production in the United States calculates greenhouse gas emissions, fossil energy use, blue water consumption and reactive nitrogen loss per kg of carcass weight.
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.
