In this paper, FCRN members Pip Brock and Daniel Tan examine how Life Cycle Assessment (LCA) is used as a tool for informing resource-use decisions. They contend that two different schools of thought - natural resource management and planning theory - would benefit by learning from each other.

This paper uses several simple emissions scenarios to illustrate how GWP* (as opposed to GWP100) can report the warming created by both short-lived greenhouse gases such as methane (CH4) and long-lived greenhouse gases such as carbon dioxide (CO2).

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 systematic review looks at dietary patterns and food sustainability in the United States. It estimates that the healthy US-style diet recommended by the Dietary Guidelines for Americans is associated with similar or higher levels of greenhouse gas emissions, energy use and water use compared to the current US diet.

This paper, co-authored by FCRN member Christian Reynolds, discusses public engagement at the authors’ ‘Take a Bite Out of Climate Change’ stand, which used infographics, short games and displays of vertical farming and insect-based foods to encourage discussion about the climate impacts of food production.

This paper uses a case study of Sheffield, UK, to explore the area of land potentially available to grow fruit and vegetables within urban areas, including both soil-based horticulture as well as soil-free controlled-environment horticulture on flat roofs.

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).

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 Nicole Tichenor Blackstone has co-authored this paper, which compares the diets recommended by the EAT-Lancet Commission and by the Dietary Guidelines for Americans (DGA). It finds areas of similarity as well as areas of divergence.

24 March 2020

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 paper finds that downplaying explicit statements of environmental benefits can be a more effective advertising strategy than prioritising the environmental aspects in product categories that are not normally seen as “green”. This is because consumers often perceive green products as performing less well than conventional products, according to the paper.

FCRN member Elin Röös has co-authored this paper, which finds that the average Swedish diet far exceeds the planetary boundaries (scaled to the per capita level) suggested by the EAT-Lancet Commission for greenhouse gas emissions, cropland use, application of nutrients and biodiversity. The diet is within the boundary for freshwater use.

16 March 2020

FCRN member Margareta Lelea of the German Institute for Tropical and Subtropical Agriculture (DITSL) has co-authored this paper, which uses the example of the pineapple supply chain in Uganda to argue that efforts to reduce post-harvest losses often neglect the uses of waste streams by local people.

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.

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.
