This paper presents the Open Source Seed (OSS) Licence, a new legal instrument (inspired by open source software) designed to protect access to plant germplasm as a commons accessible to everyone. The legally enforceable licence is being trialled with varieties of tomato, wheat and maize.

FCRN member Marie Trydeman Knudsen has co-authored this life cycle assessment of organic versus conventional milk production in Western Europe, which highlights the importance of including soil carbon changes, ecotoxicity and biodiversity in environmental assessments.

The Centre for Agroecology, Water and Resilience at Coventry University has launched a new website on agroecology, containing information about related projects, publications, policy statements and videos.

The Platform for Agrobiodiversity Research has produced an online compendium of methods for assessing agrobiodiversity, including diversity of crops, livestock, pollinators and harvested wild plants.

This book, by David Lindenmayer, Damian Michael, Mason Crane, Daniel Florance and Emma Burns, describes best practice approaches for restoring Australian farm woodlands for birds, mammals and reptiles.

This report by the RISE Foundation (Rural Investment Support for Europe), co-authored by FCRN member Elisabet Nadeu, outlines the environmental and health impacts of livestock production and consumption in the EU. The report suggests that there is a “safe operating space” for livestock production, defined at the lower bound by the provision of nutrition to humans and the maintenance of permanent pasture habitats, and defined at the upper boundary by climate impacts and nitrogen and phosphorus emissions.

WWF’s 2018 Living Planet Report finds that population sizes of thousands of vertebrate species have declined by 60%, on average, between 1970 and 2014, land degradation seriously impacts 75% of terrestrial ecosystems, and current species extinction rates are 100 to 1000 times higher than the background rate. The report attributes these impacts to rising demand for land, water and energy, and explores the impacts of agriculture, fisheries and deforestation.

A paper reviews how “working lands” such as farms, forests and rangelands can be managed to protect biodiversity and ecosystems services. The paper points out that the management of working lands can be complementary to using protected areas to conserve biodiversity.

The common weed killer glyphosate targets an enzyme only found in plants and microorganisms. However, a new paper finds that glyphosate can harm honey bees even though they lack the targeted enzyme. Glyphosate does this by changing the balance of microorganisms (some of which contain the relevant enzyme) found in the bees’ guts, making the bees more susceptible to infections.

Birds catch insects less frequently in silvopastures (grazing land with substantial tree cover) than in forest fragments, according to a study in the Colombian Andes. This suggests that silvopasture provides relatively lower quality habitat for the bird species studied. However, the paper proposes some measures to improve the quality of silvopastures as habitats for birds, including encouraging certain tree species and forming particular microhabitats, such as vine tangles and hanging dead leaves.

When given a choice between food with or without an added neonicotinoid pesticide (thought to be harmful to bees), bees initially show no preference for the pesticide, but over time choose to feed on the pesticide-laced food. This means that pesticide-treated crops may become disproportionately attractive to bees, increasing the bees’ exposure to harmful compounds. The study did not identify the mechanism by which bees develop a preference for the pesticide.

Lasers might replace poison or shotguns to stop birds from eating fruit crops, according to some farmers who have used automated laser systems to successfully defend their crops. The systems are also quieter than propane cannons and more reliable than trained falcons. However, it isn’t clear whether the lasers can harm birds’ eyes.

Writing in the Guardian, Isabella Tree of Knepp Castle Estate argues that vegan diets ignore the potential of wildlife-friendly livestock grazing methods. Tree claims that not using anti-worming agents or antibiotics allows cow dung to feed various soil organisms, contributing to soil restoration and wildlife diversity.

A new paper reviews the extent to which sustainable intensification has been achieved in England. It concludes that agricultural intensification drove environmental degradation during the 1980s. In the 1990s, however, yields became decoupled from fertiliser and pesticide use, meaning that some ecosystems services began to recover. The authors interpret their results as meaning that sustainable intensification has begun. Farmland biodiversity, however, has not recovered.

The EU-funded CAPSELLA project, which develops digital tools for agrobiodiversity, has released an online tool to guide users through the steps of taking a “spade test” to monitor soil quality. Users can also choose to upload their results to a public database.

The Trump administration has reversed a ban on using neonicotinoid pesticides (linked to declining bee populations) and genetically modified crops in over 50 national wildlife refuges (out of 560 total). Limited farming activity is permitted in some of the wildlife refuges. Previously, a blanket ban had prohibited the use of neonicotinoids and genetically modified crops in the wildlife refuges, but now decisions will be made on a case-by-case basis.

Rob Bailey and Bernice Lee of UK think tank Chatham House have written a piece exploring food system trends, including rising food demand, plateauing yields in key crop production regions, global convergence on a diet dependent on calorie-dense but nutrient-poor crops and a lack of genetic diversity in staple crops. The authors conclude that current food system trends are unsustainable, saying, “The continued intensification and expansion of agriculture is a short-term coping strategy that will eventually lead to food-system collapse.” They call for interventions at key leverage points in the food system.
