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 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).
This paper argues that substantially rebuilding the health of marine ecosystems is both necessary for human thriving and achievable within a generation. While marine ecosystems are under pressure from overfishing, pollution, oxygen depletion and other stressors, the authors point out that many remote areas of the ocean are still wild and large populations of marine mammals still exist and are capable of recovering if given the chance.
This blog post from the Global Alliance for Improved Nutrition sets out the impacts that COVID-19 is likely to have on the food system in both low- and high-income contexts, including impacts on health, livelihoods and the cost of food transport. It also suggests how the food system can be strengthened to mitigate these challenges. See this table (PDF link) for a summary.
This book looks at the tradeoffs between mitigating climate change and protecting food security, as well as the effects that climate change has on food production.
This paper reviews the evidence base around using soil organic carbon as a climate change mitigation measure. It notes that such climate solutions encompass both increasing soil carbon in soils that have not reached their maximum possible carbon content, and conserving carbon in soils that already have a high carbon content (thus avoiding losses that might otherwise have taken place).
UK food waste NGO Feedback has curated a list of recommended reading on how the coronavirus (COVID-19) crisis is linked to food systems, including the origins of the pandemic and the effects it is having on food supply chains.
This book provides technical information on food safety and quality in developing countries, using case studies of various types of food including spices, cassava, fruits and vegetables and beverages.
