Over the last year, AgMIP Principal Investigator, Cynthia Rosenzweig has been traversing the country to spread the word about AgMIP’s research projects. Last month, Rosenzweig traveled to Harvard University, Stanford University and the University of California, Berkeley to meet with students and fellow agricultural and climate change scientists.

New GEOSHARE AgMIP Tool aggregates GGCMI outputs

By Nelson B. Villoria

A GEOSHARE Tool for aggregating projected crop yields from AgMIP’s Global Gridded Crop Model Intercomparison Project

GEOshare-AgMIPtool As part of the Agricultural Model Intercomparison and Improvement Project (AgMIP), the Global Gridded Crop Model Intercomparison group helped to coordinate a fast-track multi-model multi-sector climate impact assessment as part of the Inter-Sectoral Impacts Model Intercomparison Project (ISI-MIP). AgMIP led the intercomparisons of gridded crop and agricultural economic models. (For details refer to Rosenzweig et al. (2013), Elliott et al. (2013), and Nelson et al. (2013) all available here and to Muller and Robertson (2013) available here). (more…)

AgMIP Papers Cited in IPCC AR5 Working Group II Assessment Report

Slide1 The Food Security and Food Production Systems chapter, of the newly released IPCC Working Group II Fifth Assessment Report (AR5), examines how new research since AR4 has changed our understanding of the impacts of climate change on current world food systems, as well as the projections of future impacts on those systems and likely consequences for food security. The IPCC AR5 is approved by governments as the definitive science related to climate change, vulnerability, impacts, and adaptation. (more…)

AgMIP-USDA Workshop Explores Agricultural Data Harmonization

By Carolyn Cox

Flow
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

AgMIP-MACSUR 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

By Andrew Thibodeau

Discrepancies between model predictions lead to varying assessments of the future of food security and agricultural markets A 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?

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.

Workshop kicks off East Asian Regional Teams

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…)
