AgMIP Approach to Data and Model Harmonization
AgMIP and USDA held a workshop on January 10, 2014 on “Harmonizing Agricultural Data and Models.” The workshop was organized by Jim Jones, Jerry Hatfield, Cynthia Rosenzweig, and Carolyn Cox (Coordinator of the Florida Climate Institute, which hosted the event). The purpose was to explore concepts for harmonizing agricultural databases and models being developed and used by various USDA research projects and AgMIP. Harmonization would lead to web-based data access for evaluating and improving agricultural models and using them for analyses of climate change impacts, adaptation strategies, and potential food security issues. The USDA-ARS and NIFA-funded projects are increasingly being mandated to ensure their data are open for broad use, with the recognition that data are highly valuable for use beyond the immediate goals of specific projects and represent a substantial public investment. However, even though similar data may be collected across projects, the fact that different databases and formats are used by different projects and labs makes the discovery and access to valuable datasets impractical.

AgMIP – MACSUR Memorandum of Understanding signed
Posted on Wednesday, February 12th, 2014 at 2:00 pm by Shari Lifson
The global challenge of food security for a growing world population requires the collaboration of scientists. Researchers of the Agricultural Model Intercomparison and Improvement Project (AgMIP) and the FACCE JPI knowledge hub FACCE MACSUR (Modelling Climate Change with Agriculture for Food Security) are already cooperating in many activities and jointly planning research projects. To facilitate an intensive future collaboration between the research teams in FACCE MACSUR and in AgMIP a Memorandum of Understanding (MoU) has been developed jointly and signed by representatives of both projects at the FACCE MACSUR International Symposium and Workshop of CropM on ‘Modelling climate change impacts on crop production for food security’ in Oslo.

Overview of the AgMIP Global Economic Model Intercomparison

Discrepancies between model predictions lead to varying assessments of the future of food security and agricultural marketsA model intercomparison attempts to answer – why all the difference?
Climate change is expected to have a significant impact on food security, agricultural production, and food pricing as temperatures rise. Increasing concerns over actual and potential increases in agricultural and food prices globally have galvanized many researchers into creating their own unique modeling approaches to predicting future scenarios and the degree to which these factors will be affected. Now a new study comparing the best of these climate, agricultural, and economic models, has been published in an effort to understand how and why they produce such varying predictions. (more…)
Agricultural Economics – Why don’t the models agree?
Posted on Wednesday, January 15th, 2014 at 7:56 pm by Shari Lifson
There is little doubt that climate change threatens the world’s food supply, but considerable uncertainty about how much and where. Previous modeling efforts have reported wide ranges of results for the future of prices, production and trade. Now a new study has been published that compares results from ten of the most sophisticated economic models to identify areas of agreement and disagreement and better assess the sources of differences.

Cynthia Rosenzweig answers questions from participants at the East Asia Workshop.
China, Japan, and Korea, home to over 1.5 billion people combined, are vulnerable to the effects of climate change on agriculture and possible impacts on food security. According to the Chinese Academy of Sciences both the direct and indirect (through water) impacts of climate change will negatively impact crop yields and food prices in the coming decades. (more…)
AgMIP underway in Latin America and Caribbean!

By Erik Alejandro Mencos
The diverse climate and geography of Latin America and the Caribbean present unique challenges to forecasting the impacts of climate change on agriculture and food security. Regional assessments, including how local agricultural economies will respond to climate change, can improve policymaking and adaptation in these varied areas. A new Latin America/Caribbean (LAC) AgMIP team has been formed to conduct these regional assessments using AgMIP protocols, and two kick-off workshops were recently held to initiate the work. (more…)
AgMIP PNAS paper – Economic effects of climate change on agriculture

Extent of food price increases depends on ease of expanding agricultural area, how food demand evolves, and openness of international trade.

Meeting the world’s growing demand for food in coming decades is likely to become more difficult as already stressed agricultural systems will be challenged by population growth and rising income in some of the world’s poorest regions.
Climate change will exacerbate the challenges in many dimensions. However, are the effects of climate change more serious than other threats to sustainable food security? (more…)

Freshwater Deficits Could Double Climate Effects on Agriculture Climate, agriculture, and hydrology models predict irrigation and food losses By Rob Mitchum, The Computation Institute (CI)

A warmer world is expected to have severe consequences for global agriculture and food supply, reducing yields of major crops even as population and demand increases. Now, a new analysis combining climate, agricultural, and hydrological models finds that shortages of freshwater used for irrigation could double the detrimental effects of climate change on agriculture.

Agriculture is arguably the sector most affected by climate change, but assessments differ and thus are difficult to compare. As the world’s population grows, understanding which crop types and regions will be negatively affected by climate change may make the difference between adequate food supply and food insecurity. By comparing the predictions of multiple models, scientists can assess with more confidence future climatic effects on agricultural production. (more…)
ASA Symposium – Perspectives on Climate Effects on Agriculture: The International Efforts of AgMIP

Daniel Hillel, 2013 World Food Prize Winner and lead Organizer/Presider of the special session.
An AgMIP special session was held at the annual meeting of the American Society of Agronomy on November 4th that featured presentations from most of the main groups working within the AgMIP community. Titled “Perspectives on Climate Effects on Agriculture: The International Efforts of AgMIP” the session ran from 8:00 in the morning until 4:10 in the afternoon and included 24 presentations. Each presentation will be published as a chapter in the upcoming third volume of the Handbook of Climate Change and Agroecosystems: The Agricultural Model Intercomparison and Improvement Project (AgMIP).
