This book presents recent developments, trends and challenges in turning food waste into products such as biofuel, enzymes, biopolymers and animal feed. 

This paper examines the effectiveness of different forms of ecological compensation schemes - i.e. offsetting biodiversity lost to developments such as oil palm plantations or mines - in achieving “No Net Loss” of biodiversity. Using simulations of four case studies, it finds that none of the 18 ecological compensation policy designs studied would achieve No Net Loss of native vegetation extent. 

This book discusses long-term experiments in agriculture, including their history, the insights they have produced, and the relationship of the experiments to agriculture’s environmental and social implications.

This opinion paper calls for organisers of scientific meetings to adhere to 12 principles to minimise the environmental impacts of the meetings, as outlined in the Cercedilla Manifesto. The principles cover food, transport and careful planning of remote meetings so that they are effective for all participants. The paper emphasises that nitrogen pollution is an often-neglected aspect of food sustainability.

This opinion piece by Liz Specht of the US Good Food Institute argues that taking animals out of the global food system - for example by replacing animal products with plant-based or cultivated meat products - can reduce the risk of future pandemics. Specht notes that zoonotic diseases usually pass to humans during the hunting or slaughter of wild animals or livestock.

This policy guide from the US nonprofit Centre for Biological Diversity calls for US federal, state and municipal policymakers to take immediate steps to reduce beef consumption by up to 90% and consumption of all other animal products by 50%. It draws on the research Implications of Future US Diet Scenarios on Greenhouse Gas Emissions.

This paper uses temperature and precipitation projections across the ranges of over 30,000 species on land and in water to estimate when each species will be exposed to dangerous climate conditions. It predicts that most species within a given assemblage (group of species within a habitat) will encounter inhospitable climate conditions at the same time as each other (e.g. several species might have a similar upper limit on the temperature that they are able to cope with), meaning that disruption of the overall assemblage is likely to be abrupt.

The 2020 edition of the Global Food Policy Report from the International Food Policy Research Institute looks at how to make food systems inclusive of smallholders, women, and people affected by poverty or conflict.

This paper combines data on zoonotic viruses in mammals with trends in species abundance. It finds that wild land mammal species with larger populations generally harbour a greater number of zoonotic viruses. Furthermore, among mammal species that are threatened, those that are threatened because of exploitation (e.g. hunting or wildlife trade) or loss of habitat host approximately twice as many viruses as mammals that are threatened for other reasons.
