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.

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.

The BEEHAVE model is a freely available simulation tool that can be used to understand how different stressors affect the development and survival of honeybee colonies. A newly launched update, Bumble-BEEHAVE, models the behaviour of six UK bumblebee species.

FCRN member Afton Halloran has edited this book, which outlines the role of edible insects in food systems around the world. Topics include nutrition, consumer acceptance, environmental impacts, using insects as animal feed and legal regulation.

Over two billion people in developing countries are smallholder farmers and often depend on pollinators, according to this report by the UK Collaborative on Development Sciences. The report finds that insufficient pollination has already been found across many crops in the developing world, which could negatively affect cash crops (such as coffee and cocoa) and intake of nutritious foods such as fruit and nuts. The report points to a lack of data on pollinators in developing countries, and calls for further research, education programmes and sustainable development projects incorporating bee-keeping.

European Union member countries have voted to ban three neonicotinoid pesticides. Neonicotinoids have been linked to the decline of bees and other pollinators. Neonicotinoids will be banned from use in open fields by the end of 2018, but will still be permitted inside closed greenhouses.

This book, by Sirpa Sarlio, explores various aspects of the environmental, social and economic sustainability of the global food system, discusses health and sustainability aspects of specific foods including insects and meat substitutes and sets out options for promoting healthy and sustainable diets.

This paper compares stylised, hypothetical dietary scenarios to assess the potential for reducing agricultural land requirements. It suggests that a combination of smaller shifts in consumer diet behaviour – such as reducing beef consumption by replacing with chicken, introducing insects into mainstream diets and reducing consumer waste – could reduce agricultural land requirements.

In this paper FCRN member Afton Halloran and colleagues Hanboonsong, Roos and Bruun present a life cycle assessment of insect farming, based on their research on cricket and broiler farms in north-eastern Thailand as well as a socio-economic impact analysis of this production.

While insects have physiological and biological differences which make them more efficient than traditional livestock species, little information exists pertaining to the factors which influence the assessment of the environmental sustainability of insects and their subsequent production systems.

A group of investors, worth $1.25 trillion, has contributed to a report calling for food companies to change the way in which they include protein in their products to reduce environmental risk. The FAIRR initiative’s report – The Future of Food: The Investment Case for a Protein Shake Up – argues that forward-looking investors and businesses should act now to help shape a new market in sustainable protein, with less of this macronutrient coming from animals, and more from plants (and perhaps from insects and algae).

This books provides a first reference on dietary proteins that covers the land, water, and energy usage inputs, nutritive outputs, and food applications of plant and other non-meat proteins.
