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 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.
The FAO’s 2019 edition of its “The State of Food Security and Nutrition in the World” report finds that the number of hungry people is increasing, with around 820 million people worldwide experiencing undernourishment. This year’s report also finds that around 2 billion people experience either severe or moderate food insecurity, with the phenomenon found in low, middle and high income countries.
The World Resources Institute has released its full and final report on “Creating a sustainable food future”. The report addresses the question “Can we feed the world without destroying the planet?”, specifically asking whether the food system can feed nearly 10 billion people adequately by 2050, without expanding the area of agricultural land, and while avoiding dangerous levels of climate change.
FCRN member Peter Alexander has co-authored this paper, which finds that incremental improvements in several areas of the food system (including production efficiency, reducing food waste and changing diets) could reduce agricultural land use by between 21% and 37%, depending on adoption rates.
The second edition of Nature’s Matrix sets out the recent state of debate around conservation and agriculture. It argues in favour of small-scale agroecology and food sovereignty.
This report from the FAO’s High Level Panel of Experts on Food Security and Nutrition (HLPE) explores how agroecology and other innovative approaches to food systems (such as organic agriculture, agroforestry, permaculture, climate-smart agriculture, nutrition-sensitive agriculture and sustainable intensification) can support sustainable agriculture and food security.
This paper argues that animal product alternatives (including both plant-based products and cellular agriculture) are likely to be implemented within the current “corporate food regime” and may not be compatible with a food sovereignty perspective. However, it suggests that using a “food tech justice” lens could guide animal product alternatives towards a role in a food system that considers health, equity and sustainability.
This paper, co-authored by FCRN member Alexandra Sexton (who is part of Oxford’s Livestock, Environment and People project), identifies key moments in the field of cellular agriculture from the past two decades. The first wave of largely university-based research lasted until the 2013 presentation of the cultured burger created at Maastricht University, while the second wave has seen the emergence of a start-up culture.
This book, by Nicola Randall and Barbara Smith, provides a summary of agricultural ecosystems around the world and uses case studies to illustrate the biological issues and solutions associated with several types of farming system.
This book, edited by David Barling and Jessica Fanzo, explores challenges related to protecting environmental resources while also meeting human nutritional requirements, covering a wide range of subjects relating to food security and sustainability.
This paper maps the potential for restoring forests across the world, finding that there is room for a 25% increase in forested area without interfering with existing forests or urban and cropland areas. This could store 205 Gt of carbon after several decades (for comparison, current emissions from fossil fuels and cement production are roughly 10 Gt of carbon each year).
This narrative review paper explores how understanding of nutrition and public health have changed over time, influenced by developments in science, social changes and policy-making. The paper identifies some major paradigm shifts, such as the identification of vitamins in the early 20th century, and the recognition of the link between dietary patterns and some chronic diseases in the late 20th century.
