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.
Countries attending FAO’s 40th conference in Rome discussed climate change and food security from different perspectives linking climate-action, nutrition and migration to the 2030 Agenda for Sustainable Development. Four side events related to climate change took place during this conference, which can now be watched online.
This paper details the findings of a meta-analysis of published data on the impact of increasing temperatures on the global and regional yield of wheat, rice, maize and soy.
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 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.
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, published in the journal Science, aims to establish a detailed “roadmap” for meeting the Paris climate goal. It provides not only a scenario for the CO2 emissions reductions needed but places attention on the many different policy actions needed to stay below 2°C warming. One of three main focus areas is agriculture and land use related emissions.
In this paper, using three scenarios for food demand, the researchers model and highlight the indirect relationship between greenhouse gas (GHG) emission abatement within the food supply system and the energy system, globally.
This paper argues that the strength of the linkages between the ‘Human System’ and the Earth system warrants a new paradigm of modeling which incorporates key factors in one system as variables of a model of the other.
The summary of key messages and full reports from the 1.5 Degrees conference which was held between 20-22 September 2016 in Oxford have now been published.
