In this paper, researchers from the Joint Research Centre of the European Commission investigate the extent to which variation in nitrous oxide (N2O) emissions may offset or enhance the mitigation effects of carbon sequestration in arable European soils. They employ a biogeochemical model with input data from ~8000 soil sampling locations to quantify CO2 and N2O flux associated with different agricultural practices aimed at carbon (C) mitigation.

This paper sets out principles of what the authors call “just conservation”, aiming to find a balance between the conservation of nature and social justice. The authors propose two principles to guide decision-making: the non-anthropocentric principle and the safeguard principle.

This article explains the technological changes behind the three-fold increase in global crop production between 1961 and 2014, i.e. since the Green Revolution. It examines the 58 countries that are responsible for 95% of food production and assesses the impacts of changes in land use, inputs and efficiency.

A perspective piece and an editorial have featured in the same edition of Biological Conservation (March 2018): both tackle a recent debate among conservation biologists as to whether at a local level biodiversity or species richness is changing and in what direction.

A report by the European Academies’ Science Advisory Council finds that negative emissions technologies (NETs) have ‘limited realistic potential’ and cannot be relied upon to remove carbon at the rate envisaged in the Intergovernmental Panel on Climate Change (IPCC) scenarios for avoiding dangerous climate change.

This article presents the results from a new global soil erosion model, based on a combination of remote sensing, GIS modelling and census data. It finds that accelerated soil erosion due to land use change between 2001 and 2012 is a major threat to soil and future agriculture but that previous commonly used estimates of annual global soil erosion were twice too high. In comparison with previous studies which had a mapping resolution of around 10–60 km cell size, this model with its high-resolution 250m cell size has far greater predictive power than any previous model.

This new study by FCRN member Paul Behrens and colleagues investigates the environmental impacts of a nationally recommended diet when compared to the national average diet for 37 nations across the world, including 9 middle income nations.

The planetary boundaries concept provides a theoretical upper limit on human activity which the planet is able to sustain without major perturbation to the current ‘Earth system’. Previously, nine planetary boundaries (PBs) have been proposed and recently Steffen et al. (2015) have updated these boundary definitions and assessed the current state of the position of human activity with respect to each boundary. In this article, researchers from a number of food, climate change, agricultural and environmental research institutions around the world build on this work by assessing the impact of agriculture on each PB status, based on a detailed literature review of the available research.

This new book, edited by Laura M. Pereira, Caitlin A. McElroy, Alexandra Littaye and Alexandra M. Girard, presents a diversity of collaborations between various governance actors in the management of the Food-Energy-Water (FEW) nexus and analyses the ability of emergent governance structures to cope with the complexity of future challenges across FEW systems worldwide.
