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.

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.

The new report by World Wildlife Fund, Appetite for Destruction, highlights the vast amount of land that is needed to grow the crops used for animal feed, including in some of the planet’s most vulnerable areas such as the Amazon, Congo Basin and the Himalayas.

This paper presents the findings of a food systems model that considers how specific agronomic characteristics of organic agriculture could be harnessed so as to enable it to play a greater role in sustainable food systems.
