This OECD Food, Agriculture and Fisheries report employs a meta-analysis/literature review approach to identify and analyse barriers to the adoption of “climate-friendly” policies in agriculture; that is, the adoption of measures to enhance the adaptation of farming to the impacts of climate change, and the mitigation of its contributions to greenhouse gas (GHG) emissions. It should be noted that the report does not go into specifics about what constitutes a climate-friendly practice: this is taken to be an understood concept and the focus of the report is on the barriers to adoption of these measures, not the measures themselves.

Recognising that changing what people eat can make a major contribution to the environmental performance of the food system, the new and updated Livewell Plates in this report illustrate the minimal dietary changes required to reach the 2 °C climate target. The report presents simple steps – such as eating more plants, legumes and grains –  that could help cut food-related greenhouse gas emissions by 30% by 2030.

In this short perspective piece, researchers from the Netherlands, USA and the UK critically assess the COP21 4 per 1000 initiative, which seeks to increase global yearly agricultural soil organic carbon sequestration by 4‰ (= 0.4%, or 1.2 billion tonnes). The authors argue that as soil organic matter (SOM) also contains nitrogen (N), with a C-to-N ratio always approaching 12, this will require the sequestration of an extra 100 million tonnes of N per year, and they question the feasibility of achieving this.

A new resource has been created by the Carbon Brief, which brings together data from a number of indicators that show the effects of climate change, showing trends in our climate, atmosphere, oceans, and the cryosphere (ice)

This paper discusses EU climate and agriculture policy instruments and analyses how these can motivate farmers to adopt soil carbon sequestration projects.

This report from the International Panel of Experts on Sustainable Food Systems (IPES-Food) looks at how cities are finding innovative ways to implement food policies. It focuses on five case studies of cities that have developed concerted urban food policies − to either ensure access to decent, nutritious food for all, to support farm livelihoods or to mitigate climate change.

This study presents estimates of how changes in climate might affect the value of European farmland. Based on data for over 41 000 farms, the results suggest that their economic value could drop by up to 32%, depending on the climate scenario considered. The models represent severe, moderate and mild outcomes, respectively.  Farms in southern Europe are particularly sensitive to climate change and could suffer value losses of up to 9% per 1 °C rise.

This paper highlights the lack of inclusion of food consumption in the climate change policy debate. It presents an analysis of how changing from beef to beans could help achieve GHG reduction targets in the US.

The purpose of this policy guidance note is to guide policy makers at country level to identify entry points for assessing and addressing food security and nutrition (FSN) in the face of climate change. It  includes background information on how climate change and variability affect the agriculture sectors and FSN and how the agriculture sectors and dietary patterns contribute to GHG emissions.

This paper takes countries’ mitigation targets (Intended National Determined Contributions, or INDCs), submitted since the Paris Climate agreement, and, using supplementary information from other official documents, quantifies how much of the promised actions are related to Land Use, Land Use Change and Forestry (LULUCF, primarily deforestation and forest management).

This research calculates the carbon footprint of a meal to give a tangible example, aimed at the public in the US, about how daily food decisions can affect deforestation and greenhouse gas emissions (GHGe). The study uses a life-cycle assessment (LCA) approach that takes into account GHGe arising from the conversion of mangrove to cattle pastures and mangrove to shrimping ponds as well as from forests to pasture (cattle induced deforestation).

What is the latest science on soil's ability to pull carbon pollution out of the atmosphere? Breakthrough Strategies hosted a webinar on April 24 on the Technical Potential of Soil Carbon Sequestration. It featured three of the world’s leading experts on strategies for drawing carbon pollution out of the atmosphere and storing it in soils: Keith Paustian, Jean-François Soussana, and Eric Toensmeier.
