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 outlines the main sustainability challenges linked to nitrogen, including inadequate access to nitrogen fertiliser in some parts of the world and excessive fertiliser application in other areas, leading to water pollution, algal blooms and risks to human health. The paper argues that solving nitrogen problems would have co-benefits for other sustainability issues such as hunger, air, soil and water quality, climate and biodiversity.
This commentary article sets out five priorities for developing the so-called “blue economy” (i.e. ocean-based activities such as fishing, aquaculture, tourism, seabed mining and shipping) in a way that is both environmentally sustainable and socially equitable. The article notes that human activities are already negatively affecting ocean ecosystems and that future economic development of the oceans may have further, sometimes poorly understood, impacts on both the environment and people.
This interactive feature from the Global Reporting Program, an investigative journalism organisation, uses text, images and video to explore the fishmeal supply chain, including its sources, its uses in aquaculture, overfishing, waste sludge from fishmeal factories and competition between industrial fishmeal producers and small-scale fish processors.
This book presents case studies and guidance on extracting high-value compounds from waste and by-products from foods such as dairy, meat, sweet potato, cereals and olive oil.
This book examines how people can be exposed to arsenic through drinking water and different types of food in several areas of the world, and sets out some strategies to reduce arsenic accumulation in rice.
This report from Farm Animal Investment Risk and Return (FAIRR) (a London-based investor initiative focused on the environmental, social and ethical issues of factory farming) estimates that the global meat substitute market is worth almost $20 billion and is predicted to grow by 7-9% annually.
This review paper finds that the number of bacterial strains that are resistant to antimicrobials is increasing in both pigs and chickens. The paper synthesises hundreds of studies from low- and middle-income countries (LMICs) to develop maps of antimicrobial resistance. Hotspots of antimicrobial resistance are found in India and China, with resistance also developing in Brazil and Kenya.
This book by Julian Cribb examines the links between food, conflict, hunger and ecological collapse, and develops recommendations for how to build a sustainable global food system that defuses tensions and avoids the mass displacement of people.
This report from the Food and Land Use Coalition proposes ten critical transitions that could enable the food system to provide healthy diets for nine billion people by 2050 while also protecting the climate and biodiversity. The transitions are estimated to provide over 15 times more social benefit than their investment cost, which is likely to be less than 0.5% of global GDP.
The Intergovernmental Panel on Climate Change (IPCC) has published a special report reviewing the impacts of climate change on the oceans and cryosphere (ice gaps, glaciers and frozen ground), incorporating evidence that has been published since the IPCC’s Fifth Assessment Report and Special Report on Global Warming of 1.5°C. It finds that climate change has shrunk ice sheets, glaciers and sea ice as well as heated permafrost (ground that normally remains frozen all year).
FCRN member Anna Birgitte Milford of the NIBIO (Norwegian Institute of Bioeconomy Research) has co-authored this paper, which studies the impact of various variables on meat total meat and ruminant meat consumption levels (both total and ruminant) in 137 countries. The paper assesses factors which had previously not been used together in similar analyses, including economic, cultural and natural factors (e.g. land availability and climate).
This paper explores ways of ending hunger without causing excessive environmental damage. It finds that ending hunger through economic growth alone (an approach that would try to increase overall food availability without addressing food consumption inequality) would require 20% more food production by 2030 than in business-as-usual, as well as generating higher carbon emissions and using more agricultural land.
This paper models the greenhouse gas (GHG) emissions and water footprints of both baseline consumption patterns and nine different healthy diets that prioritise plant ingredients for 140 countries. The authors find large differences in GHG and water footprints between countries, with vegan, two-thirds vegan or “low food chain” (including insects, molluscs and forage fish) diets generally leading to the greatest footprint reductions.
This book explores the controversies surrounding the use of geographical indication labels on food and their relationship to different forms of socio-economic development.
In August 2019, the Intergovernmental Panel on Climate Change published a special report on climate change and land, covering a variety of interlinked topics including desertification, land degradation, food security, water scarcity, negative emissions, and policy options for both adaptation and mitigation.
This paper quantifies the carbon emissions, water use and land use associated with the consumption of food excess to requirements, on the basis that overnutrition has sometimes been classified as a form of food waste. It finds high geographical variation in the environmental impacts of so-called excess food consumption, with impacts being an order of magnitude greater in Europe, North America and Oceania than in sub-Saharan Africa.
This paper reviews the literature on the supply chain of phosphorus, a nutrient required in agriculture, and finds that current reporting is inadequate regarding phosphorus reserves and resources, losses along the supply chain, environmental and sociopolitical externalities, and open access to data.
This paper models the global land use change implications of three different dietary scenarios up to the year 2100: business as usual with a continued shift away from pulses and starchy roots and towards animal products; a 95% global reduction in consumption of ruminant products compared to business as usual, with ruminant products to be replaced by cereals, pulses, starchy roots and oilcrops but other meat types to be consumed as in business as usual; and a 95% reduction in consumption of both ruminant and monogastric products.
