Showing results for: Climate trends/projections
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.
This paper takes as its starting point the mainstream projections that in future, global food production will need to increase by another 60–110% by 2050, to keep up with anticipated increases in human population and changes in diet (it should be noted, however, that the need and feasibility of such increases is contested (see), with many arguing that dietary change and waste reduction can reduce the need for production increases (see)).
The ‘2016 Food, Water, Energy and Climate Outlook’ by the MIT Joint Program on the Science and Policy of Global Change finds that even if commitments from the COP21 climate agreement are kept, many staple crops in various regions are still at risk of crop failures through extreme events, but at the same time, yields in many regions are projected to increase.
