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.
The Intergovernmental Panel on Climate Change (IPCC) has brought out a handbook to help its scientists communicate climate change issues effectively.
Insects may not be the environmentally-friendly alternative protein source that the FAO and many entrepreneurs hope, according to Oxford University doctoral candidate Joshua Evans.
A report by the social enterprise Circle Economy finds that today’s economy is only 9.1% circular, based on their newly launched Global Circularity Metric. To move away from the current linear economic model, the report recommends extracting fewer resources, wasting less, optimising the resources we already have and cycling more resources back into the economy.
A report by the European Academies’ Science Advisory Council finds that negative emissions technologies (NETs) have ‘limited realistic potential’ and cannot be relied upon to remove carbon at the rate envisaged in the Intergovernmental Panel on Climate Change (IPCC) scenarios for avoiding dangerous climate change.
This opinion piece by Peter Horton of the Grantham Centre for Sustainable Futures discusses the failures of the current food system and sets out some possible solutions to achieve sustainable food security for all.
No country meets basic needs for its citizens at a globally sustainable level of resource use, according to a study by researchers from the University of Leeds.
The Financial Times explores several emerging trends in the global food industry, including eating insects, new retail models in China, sugar taxes, food waste monitoring and genetically modified crops and animals.
Ikea has introduced a “Better Chicken Programme” aimed at improving animal welfare in the supply chains for its in-store cafes.
A Climate Action Tracker report outlines and quantifies the main opportunities to reduce food-related non-CO2 greenhouse gas emissions, particularly CH4 and N2O.
Geoengineering to fix climate change could harm biodiversity, according to two modelling studies.
At the Global Forum for Food and Agriculture (GFFA) 2018, the director general of the United Nations Food and Agriculture Organization (FAO) spoke about the need for lower emissions from the livestock industry. In addition to efficiency gains, Graziano da Silva suggested that governments target the demand side with policies that reduce meat and dairy consumption. He said that alternative sources of protein, such as fish and pulses, are available and should be used.
In this brief communication paper published in the first volume of the new journal Nature Sustainability, researchers from the US and Belgium assess the impact of international trade on global food supply, at the level of individual nutrients, rather than total calories. Based on their hypothetical comparison of food supply in a world with and without trade, they argue that international food trade is essential for global food security.
The report ‘Redefining protein: adjusting diets to protect public health and conserve resources’ looks at different protein sources and their environmental, health and social impact. The authors note that ‘transitioning to diets with more plant-based ingredients is an essential action to promote health, food security, and long-term environmental sustainability. However, the impact on health and sustainability outcomes can vary depending on the types of foods with which meats are replaced.’ This report summarises and analyses the available academic literature on the impacts of whole food protein options alternative to meat, with an emphasis on legumes, nuts and seeds, eggs, seafood, and dairy.
This article examines global overuse of freshwater resources and how more sustainable irrigation practices could impact other environmental and developmental targets in the SDGs. It finds that the main likely effects are 1) increased food prices due to lower productivity and/or production costs as water prices increase, and 2) cropland expansion and associated extra GHG emissions of 0.87 gigatonnes of carbon.
This book by Helmut Traitler, Michel Dubois, Keith Heikes, Vincent Petiard, David Zilberman provides an overview of current food systems and potential future directions for agriculture and food.
This article in Food Navigator discusses a start-up company which produces dairy proteins, from sugar and genetically modified yeast. The resulting proteins can be used in a wide range of products to replace animal-produced dairy protein, such as in chocolate, ice cream, protein shakes and yoghurt.
The European Commission’s Joint Research Centre has developed a new online tool. DOPA Explorer 2.0 provides allows users to explore and compare protected areas, with regard to their species and ecosystems, and the pressures they are exposed to through human development.
