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 report explains several trends and issues impacting the edible fats and oils system, including increasing demand, land use, public health, climate impacts, restrictions on trans fats, the search for alternatives to palm oil and soy, and supply chain transparency.
FCRN member Samuel Smith of international sustainability non-profit Forum for the Future has contributed to this report, which sets out the case for organisations to act on the sustainability of all the fats and oils in their supply chains, including but not limited to palm oil.
This paper evaluates the impact of diet on risk factors for heart disease. It finds that replacing red meat with “high-quality” plant protein sources (such as legumes, soy or nuts), but not with fish or “low-quality” carbohydrates (such as refined grains and simple sugars), results in improvements in total and low-density lipoprotein cholesterol.
This paper reviews studies where changes in both productivity and species richness have been tracked at the same location, following changes in the intensity of land use. On average, intensifying land use leads to a 20% gain in output and a 9% decrease in species richness, but there is considerable variation between different contexts.
This book, edited by Mette Vaarst and Stephen Roderick, reviews key challenges and solutions in improving the health and welfare of organic farm animals, including case studies from organic farming of dairy and beef cattle, sheep and goats, pig and poultry.
This perspective piece argues that new plant breeding technologies such as CRISPR-Cas could contribute to global food security and poverty reduction by increasing agricultural yields and smallholder incomes. The authors note that careful regulation, field testing and communication will be necessary for successful implementation, along with royalty-free access for smallholders.
This report from the US National Academies of Sciences, Engineering, and Medicine identifies emerging scientific advances that could help to make the US food system more resilient to rapid changes and extreme conditions, as well as making agriculture more efficient and sustainable.
This paper shows that pollinator services in agricultural landscapes that have been highly altered from their natural state are lower than would be predicted from a simple count of pollinator species. The paper bases its estimates on a study of the evolutionary relationships between pollinators and extensive surveys of pollinators.
This book identifies common causes of food waste in developing countries and presents examples of successful food preservation methods for different food types in developing countries.
This paper assesses the agricultural water use efficiency of different food types based on their nutrient content, instead of the conventional approach of assessing water use in terms of litres used to produce a certain weight of food. The purpose of the study is to determine whether higher intakes of nutrient-rich foods such as fruit, vegetables and seeds might conflict with the aim of minimising agriculture’s water use.
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.
