While some of the food system challenges facing humanity are local, in an interconnected world, adopting a global perspective is essential. Many environmental issues, such as climate change, need supranational commitments and action to be addressed effectively. Due to ever increasing global trade flows, prices of commodities are connected through space; a drought in Romania may thus increase the price of wheat in Zimbabwe.
This book presents recent developments, trends and challenges in turning food waste into products such as biofuel, enzymes, biopolymers and animal feed.
This opinion paper calls for organisers of scientific meetings to adhere to 12 principles to minimise the environmental impacts of the meetings, as outlined in the Cercedilla Manifesto. The principles cover food, transport and careful planning of remote meetings so that they are effective for all participants. The paper emphasises that nitrogen pollution is an often-neglected aspect of food sustainability.
This paper examines the effectiveness of different forms of ecological compensation schemes - i.e. offsetting biodiversity lost to developments such as oil palm plantations or mines - in achieving “No Net Loss” of biodiversity. Using simulations of four case studies, it finds that none of the 18 ecological compensation policy designs studied would achieve No Net Loss of native vegetation extent.
FCRN member Damian Maye of the University of Gloucestershire has put together a list of academic and non-academic resources on COVID-19 and sustainable food systems. It is organised into categories including agricultural labour, food access and security, local food networks, food waste and food system commentaries.
This book examines the material properties and sustainability of various polymers that can be used for food packaging, such as bioplastics and edible food packaging.
The 2020 edition of the Global Food Policy Report from the International Food Policy Research Institute looks at how to make food systems inclusive of smallholders, women, and people affected by poverty or conflict.
This paper combines data on zoonotic viruses in mammals with trends in species abundance. It finds that wild land mammal species with larger populations generally harbour a greater number of zoonotic viruses. Furthermore, among mammal species that are threatened, those that are threatened because of exploitation (e.g. hunting or wildlife trade) or loss of habitat host approximately twice as many viruses as mammals that are threatened for other reasons.
This paper uses temperature and precipitation projections across the ranges of over 30,000 species on land and in water to estimate when each species will be exposed to dangerous climate conditions. It predicts that most species within a given assemblage (group of species within a habitat) will encounter inhospitable climate conditions at the same time as each other (e.g. several species might have a similar upper limit on the temperature that they are able to cope with), meaning that disruption of the overall assemblage is likely to be abrupt.
This blog post from University of Oslo’s Centre for Development and the Environment argues that the spread of zoonotic diseases cannot be halted simply by closing wet markets (often portrayed in the Western media as the source of viruses). Rather, it argues, deeper changes in the food system are required, since zoonotic diseases have also been linked to deforestation and industrial meat production.
This book examines how the food system can adapt to be able to produce enough food in a changing climate. The authors present global policy options and list key foods that could help, including algae, caribou and kale.
This report from the International Institute for Environment and Development explores the potential to use “biocredits” to protect biodiversity. Biocredits are an economic instrument that allows the creation and trade of “biodiversity units”. Biocredits would be bought by people or institutions that want to invest in protecting biodiversity, and the money from their initial sale would fund conservation activities that increase biodiversity above a baseline level. The report distinguishes between biocredits and biodiversity offsets, which are used to compensate for habitats that have been destroyed, e.g. because of construction projects.
This paper studies the relationship between food system drivers and sustainability for a sample of low-, middle- and high-income countries. The aim of the research is to provide a clearer understanding of what drives food system sustainability, in order to better target interventions and investments to transform the food system.
This paper models the production of six food crops, and finds that only 11-28% of the world’s population (depending on crop) would be able to meet their demands for those crops by using only food produced within a 100 km radius, based on current production and consumption patterns. The aim of the paper is to assess the physical constraints that limit the extent to which food supply can become localised and thus inform the ongoing debates around local food and food sovereignty.
The Good Food Institute (US-based non-profit) has launched a database of funding opportunities in the alternative protein space, including opportunities related to plant-based proteins, cellular agriculture and proteins derived from fermentation.
This blog post by John Lynch of the Oxford Livestock, Environment and People programme explains how GWP* can be used to describe the warming effect of both short- and long-lived greenhouse gases, particularly when applied to livestock.
This book examines how communities of microorganisms (microbiomes) affect their multicellular hosts, including soil, plant, animal and human hosts. It discusses how microbiomes affect the behaviour, nutrition and disease susceptibility of their hosts.
This paper uses several simple emissions scenarios to illustrate how GWP* (as opposed to GWP100) can report the warming created by both short-lived greenhouse gases such as methane (CH4) and long-lived greenhouse gases such as carbon dioxide (CO2).
