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.

This paper argues that substantially rebuilding the health of marine ecosystems is both necessary for human thriving and achievable within a generation. While marine ecosystems are under pressure from overfishing, pollution, oxygen depletion and other stressors, the authors point out that many remote areas of the ocean are still wild and large populations of marine mammals still exist and are capable of recovering if given the chance.

This blog post from the Global Alliance for Improved Nutrition sets out the impacts that COVID-19 is likely to have on the food system in both low- and high-income contexts, including impacts on health, livelihoods and the cost of food transport. It also suggests how the food system can be strengthened to mitigate these challenges. See this table (PDF link) for a summary.

This book looks at the tradeoffs between mitigating climate change and protecting food security, as well as the effects that climate change has on food production.

This paper reviews the evidence base around using soil organic carbon as a climate change mitigation measure. It notes that such climate solutions encompass both increasing soil carbon in soils that have not reached their maximum possible carbon content, and conserving carbon in soils that already have a high carbon content (thus avoiding losses that might otherwise have taken place).

UK food waste NGO Feedback has curated a list of recommended reading on how the coronavirus (COVID-19) crisis is linked to food systems, including the origins of the pandemic and the effects it is having on food supply chains.

This book provides technical information on food safety and quality in developing countries, using case studies of various types of food including spices, cassava, fruits and vegetables and beverages.

This report from global network Future Earth identifies the risks perceived by scientists to be most likely to lead to a global systemic crisis. Most of the scientists interviewed mentioned at least four of the five following risks: food, climate change, extreme weather, biodiversity loss and water.

FCRN member Lukas Paul Fesenfeld has co-authored this paper, which surveys people from China, Germany and the United States to assess levels of public support for various types of policy aimed at reducing meat and fish consumption. It explores how “packaging” several policies together can increase acceptance among voters.

FCRN member Hayo van der Werf has co-authored this perspective paper, which argues that current Life Cycle Assessment (LCA) methodologies tend to favour intensive farming systems and misrepresent organic and agroecological systems.

This page is a collection of resources related to coronavirus (COVID-19) and the food system.

Our World in Data has published this piece, which breaks down the extent to which the differences in carbon footprints of food categories can be attributed to methane, a short-lived greenhouse gas which has attracted controversy over how its climate impact is measured.

This e-book from the international climate nonprofit Project Drawdown reviews the world’s options for reducing greenhouse gas emissions. The top solutions related to food and land (see section 1.2 of the book) are reducing food waste, shifting to plant-rich diets, protecting ecosystems such as peatland and forests, and shifting agricultural practices (e.g. improving rice production).

This book describes Lume, a method for analysing the economic and ecological impacts of agroecological farming systems. It includes a case study of family farms in a region of Brazil affected by droughts.

According to this meta-analysis of 60 studies, cover crops on agricultural land can increase soil microbial abundance, activity, and diversity relative to land left bare between crops, with the effect varying with climate and how the farm is managed (e.g. tilling). The paper does not discuss the extent to which this change in soil microbiome affects crop yields.

This paper sets out how far different sources of methane (both agricultural and non-agricultural) can be reduced by 2050, via technical changes. It argues that since methane accounts for about 40% of the warming effect of all greenhouse gases in the short term (because of its high Global Warming Potential but short atmospheric lifetime), reducing methane emissions is therefore useful for mitigating climate change between now and 2050.

This paper reviews initiatives for conserving insects and argues that they must be expanded globally to protect insect populations. It also argues that the value of insects to society must be better communicated to people, e.g. through focusing on the benefits of iconic insect species or particular landscapes.

This book examines a variety of regenerative farming systems, including agroecology, indigenous food systems, small-scale fisheries, food sharing, coffee micro-mills, foraging and reuse of food waste.

Microplastics are tiny fragments of plastic formed as larger pieces break down in the environment, or else intentionally manufactured (e.g. as microbeads for cleaning products or pellets for industrial use). This paper reviews the current state of knowledge on their human health implications and effects on ecosystems.
