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.
In this paper, FCRN members Christian Reynolds and Tom Quested review the effectiveness of different consumption-stage measures to reduce food waste. Examples of successful interventions include serving food on smaller plates (which can reduce food waste by up to 57%) and changing school nutritional guidelines (which reduced waste of vegetables by 28% because fewer students selected vegetables and those who did select vegetables ate more of them).
FCRN member Pat Thomas of UK campaign group Beyond GM has helped to set up the website A Bigger Conversation, which aims to bring together experts and thinkers, including scientists, academics, farmers, breeders and grassroots leaders, from multiple disciplines and multiple sides of the debate on genetic engineering in the food system.
This report by US non-profit Centre for International Environmental Law reviews research on the human health impacts of plastics throughout their lifecycle, including extraction of fossil fuels, refining and production, consumer use, waste management, fragmenting and microplastics and accumulation of plastics in food chains.
This report by international non-profit Forum for the Future outlines some key trends in sustainability that the authors expect will be important over the next decade. The report also aims to equip decision-makers with a greater ability to influence systems at the scale necessary to tackle global challenges.
This report from the Japanese Institute for Global Environmental Strategies shows how lifestyles would have to change in industrialised countries and some industrialising countries in order to meet climate change targets.
This paper uses climate models to estimate that average precipitation across many crop production areas will change by more than natural variability throughout the 21st century. Changes are seen even if emissions are relatively low, but meeting the Paris climate goals could reduce the extent of cropland that is affected.
FCRN member Alexandra Sexton describes the narratives and counter-narratives that have been used to talk about alternatives such as cultured meat and plant-based meat replacements.
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.
This book by Mike Berners-Lee aims to provide a big-picture overview of how to solve the many environmental issues the world is facing now, including both systemic and personal paths of action. It is aimed at a wide audience including both policymakers and the general public. Chapter 2 is about food.
This paper analyses how different agriculture and forestry activities affect biodiversity and carbon sequestration. In 2011, the top driver of losses to bird species richness was cattle production, while the greatest driver of losses to net carbon sequestration (relative to sequestration if natural vegetation were allowed to grow) was forestry.
This paper retrospectively models the impacts of ocean warming on the productivity of 235 fish populations around the world representing around one third of reported global catch. It uses a temperature-dependent population model to estimate that the overall maximum sustainable yield of the fish populations dropped by 4.1% between 1930 and 2010.
This paper models the impacts that the Paris Agreement on climate change would have on seafood production. It finds that three quarters of maritime countries would benefit from the Agreement’s implementation.
This book discusses resilience in agriculture, using economic, ecological and sociological perspectives. Topics covered include biodiversity, ecosystem services, land sparing versus land sharing, and sustainable intensification.
FCRN member Peter Stevenson of Compassion in World Farming has produced a policy briefing for the Fourth Session of the UN Environment Assembly, arguing that industrial livestock production has a detrimental impact on soils, water, biodiversity and food security and also undermines small-scale livestock farmers.
