This book reviews research on the development of biopesticides, including those based on microbes, natural substances and pheromones.

This book addresses food loss and waste from a range of perspectives, looking at key stages in the supply chain, different types of commodity and different regions in the world.

This book presents case studies and guidance on extracting high-value compounds from waste and by-products from foods such as dairy, meat, sweet potato, cereals and olive oil.

This report from the UK charity Waste and Resources Action Programme (WRAP) provides the latest estimates for food losses and food waste in primary production (i.e. on farms) in the UK. It finds that 3% of food harvested is wasted at the farm stage (sent to waste treatment such as composting without first being used for another purpose, or left in the field) and 4% is surplus (material intended for food uses that ends up being redistributed to people, fed to animals or used for other purposes), making a total of 7%.

This blog post by Mia MacDonald of US think tank Brighter Green and Gene Baur of Farm Sanctuary explains the African swine fever epidemic that is currently affecting China and Southeast Asia. Over 3 million pigs have already been killed by the disease or culled as a preventative measure. The disease has not yet been passed on to humans.

Extreme weather events such as frosts, heavy rains and droughts are the main drivers of lower olive yields in Italy, according to Professor Riccardo Valentini of the Euro-Mediterranean Centre for Climate Change. Italy has experienced a 57% drop in olive oil production in 2018.

This paper maps interruptions to food production across the world between 1961 and 2013 and highlights the links and tradeoffs between events in different food sectors, including crops, livestock, fisheries and aquaculture.

The UK government has set out a waste and resources strategy for England, aiming to eliminate all avoidable waste by 2050 and promote a circular economy. Proposed measures include taxing plastic that contains less than 30% recycled material and providing food waste collection to all householders and relevant businesses.

Losses of wheat, rice and maize to insects could increase by 10 to 25% per degree Celsius of climate warming, according to this paper. This is due to two main factors: insects have faster metabolisms at higher temperatures and therefore need to eat more; and insect population growth rates will also change with temperature.

The World Wildlife Fund has released a report measuring on-farm crop waste at various locations in the United States. During the 2017-18 growing season, 40% of tomatoes, 39% of peaches, 2% of potatoes and 56% of romaine lettuce were left in the field. Causes of waste at the farm stage include strict quality standards, damage due to weather, variable consumption patterns and unpredictable labour supply. Some growers pointed out, however, that the nutrients in on-farm waste food are almost always recycled, e.g. as animal feed or by ploughing the waste back into the field.

Fresh fruit and vegetables deliberately withdrawn from the market and destroyed under the EU’s Common Agricultural Policy accounted for 5.1 Mt CO2 eq. in embedded production-stage emissions between 1989 and 2015, according to research by FCRN member Stephen Porter of the University of Edinburgh.

A report from food waste charity Feedback investigates what role supermarkets play in the production of food waste on UK farms.

This paper looks at how we can achieve greater food and nutrition security in a sustainable manner by reducing waste and it also analyses how losses impact overall food system efficiency.  It quantifies the food wasted throughout the food chain (10 stages) from primary production to human food consumption and also looks at the impact of livestock production on both food system biomass efficiency and feed crop losses. The paper defines wasted food energy of livestock production in terms of its poor efficiency in feed conversion ratios (ie. only some of the feed livestock consume end up as meat and dairy, with the rest loss via respiration, dung and urine).

Recent assessments have strongly suggested that meeting the widely agreed target of limiting global warming to less than 2°C will require the deployment of substantial carbon sinks in addition to measures to curb greenhouse gas (GHG) emissions. This perspective article examines the latest research and thinking on the ability of agricultural soil management to reduce GHG emissions and promote soils as carbon sinks, and the practical feasibility of implementing available soil management practices

This editorial article focuses on an aspect of agricultural food loss and waste, not often considered: the effects that a reduction in food loss and waste at the production stage, might have on the species that have become reliant on food waste.
