AgMIP – CCAFS team up to investigate index insurance in Senegal

AgMIP-CCAFS-workshop-CoverA joint CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) and Agricultural Model Intercomparison and Improvement Project (AgMIP) meeting was held June 3-4 to kick off a USAID-CIAT (International Center for Tropical Agriculture) funded study “Increasing Productivity and Livelihoods in the Nioro du Rip Basin in Senegal” at the Earth Institute at Columbia University in New York. The meeting brought together researchers from CCAFS, the International Research Institute for Climate and Society (IRI), NASA Goddard Institute for Space Studies, University of Florida, University of Ghana, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) and the Center for Climate Systems Research. The goal of the study is to investigate how index insurance can be optimized to encourage yield-enhancing farm management choices in Senegal. (more…)

Are increasing levels of CO2 causing hidden hunger?

By Andrea Calderon Irazoque

corn According to a recent commentary “Food Security: Fertilizing hidden hunger” by Müller C. and others published in Nature Climate Change, CO2 fertilization and climate change will likely exacerbate macro and micro-nutrients deficiency in crops, jeopardizing one of the most important millennium development goals: to eradicate extreme poverty and hunger. This declining nutritional content could lead to “hidden hunger”– defined by the authors as an “insufficient supply of vitamins and minerals in diets with sufficient calorie content.” (more…)

Soils data workshop focuses on assessments in Africa

By Nick Hudson

AgMIPSoilsWorkshop Crop models have been extensively tested for yields, but their validation for soil water balance, and carbon and nitrogen cycling in agricultural systems has been limited. In order to improve the use of soil data in assessments of climate change impacts on agriculture, the Agricultural Modeling Intercomparison and Improvement Project (AgMIP) and Columbia University’s Center for Climate Systems Research (CCSR), hosted a joint workshop April 9-11 funded by USAID. The workshop, part of the AgMIP GRIDded crop modeling initiative (AgGRID) brought together leaders from AgMIP soils team and AgGRID along with experts from the Gates-funded African Soil Information Service (AfSIS) project as well as other soil and Africa experts.

Maize Models Compared in New Paper

By Jean-Louis Durand, Institut National de la Recherche Agronomique, France

MiazeTanzania Our climate is changing and crop simulation models can project how climatic factors will affect food production in the coming decades, and what adaptations in farmers’ fields could stabilize global food security. Crop models are computer tools used in combination with present scientific knowledge to project yields under future climate. A recent publication, “How do various maize crop models vary in their responses to climate change factors?” by Bassu and others in the journal Global Change Biology addresses questions regarding our confidence in how well the maize simulation models can predict growth and yields under future climate change.

New Innovations for the Use of Site-Specific Data

By Molly B Schneider

Recently several studies by AgMIP researchers have been released that highlight the development of improved methods for the use and management of site-specific data for agricultural research. Site-specific data consists of more detailed information about local environmental and economic variables that could impact production. By using site-specific data researchers will be able to create more accurate predictions of future trends in agricultural production. These articles highlight three updated techniques: production modeling, data sharing and yield assessments.

Southern Africa AgMIP models adaptation

By Juliet Ogola and Job Kihara

The Southern Africa AgMIP research team publishes popular article titled “Climate change adaptation: How will we feed people in 2050?”

Feedin2050 Last week the Southern Africa AgMIP research team published a popular article titled “Climate change adaptation: How will we feed people in 2050?” in the electronic journal Water Wheel. The article presents the team’s approach and key findings, thanks to Dr. Yacob Beleste Principal Investigator. However the results are only a small part of what AgMIP is doing in Sub-Sahara Africa, and more publications are upcoming.

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…)
