Knowledge for better food systems

Showing results for: Global

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 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 report from the Centre for Agroecology, Water and Resilience at Coventry University traces the work done on agroecology by the United Nations Food and Agriculture Organisation (FAO) and suggests how civil society, academics and other actors can encourage and strengthen this work.

This report by conservation organisation WWF and food company Knorr lists 50 foods that, it argues, we should eat more of. Foods were selected based on nutrition, environmental impact, flavour, accessibility, acceptability and affordability.

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.

This report written by the International Livestock Research Institute for the World Economic Forum’s Meat: the Future series explores the role of the livestock sector in developing and emerging economies to 2030 and beyond.

This report from the FAO reviews the state of ‘biodiversity for food and agriculture’, i.e. any biodiversity that contributes in some way to food production. It finds that 26% of livestock breeds are at risk of extinction. Crop diversity is declining, with only 9 crop species accounting for 66% of crop production. One third of fish stocks are overfished, and a further 60% are being fished at their maximum sustainable capacity.

Climate mitigation policies rarely account for the time lags associated with land-based greenhouse gas mitigation policies such as reforestation, bioenergy with carbon capture and storage (BECCS) or reduction of agricultural emissions, argues this paper, making it unlikely that commitments under the Paris Agreement will be met.

The 2019 Green Alliance Annual Debate discusses the ways in which earth observation and data science can improve our understanding of and ability to address environmental issues - for example, monitoring deforestation or water levels in reservoirs in real time through satellite images.

This book explores how climate change will affect food security and availability, and outlines ways of adapting agriculture to cope under a different climate.

This paper, by John Lynch of the University of Oxford’s LEAP project, finds that carbon footprint studies of beef cattle typically do not report separate values for emissions of different greenhouse gases such as methane and nitrous oxide. Instead, studies generally report only an aggregated figure in the form of the 100-year Global Warming Potential (GWP100) as CO2-equivalent.

This paper, by researchers from the University of Oxford’s LEAP project, models the climate impacts of beef cattle and cultured meat over the next 1000 years using a climate model that treats carbon dioxide, methane and nitrous oxide separately, instead of using the widespread Global Warming Potential, which assigns a CO2-equivalent value to each greenhouse gas according to warming caused over a specified timeframe.​

Over 40% of insect species are at risk of extinction over the next few decades and 75% to 98% of insect biomass has already been lost, according to this review of the current state of knowledge about insect declines, with habitat loss through conversion to intensive agriculture being the main driver. Agro-chemical pollutants, invasive species and climate change are also driving insect declines.
