Changing and variable climate is expected to have a significant impact on agriculture in both developed and developing countries. Models help generate information on the type and magnitude of likely impacts. However, there are multiple crop and economic models providing divergent results on where impacts will be felt as well as the severity of these impacts. Further, there may also be locations where the impacts may be beneficial. The lack of consistent impact data reduces the ability of governments to plan responses to climate variability and change in relation to agriculture and food security. It also reduces effective decision-making on adaptation finance allocations. Founded in 2010 by a group of US and international agricultural modelers, the Agricultural Model Intercomparison and Improvement Program has grown to encompass a global community of more than 600 agricultural modelers addressing these major questions. This charter provides the basis by which the Agricultural Model Intercomparison and Improvement Program operates and establishes standards and protocols for agricultural modeling. This includes ways to initiate new activities and develop regional partnerships. The goal is to incorporate key drivers affecting food security so as to improve coordinated global and regional assessments. AgMIP also addresses the requirements for innovative agricultural models of the future – including improved simulation of agricultural systems and adaptations important to sustainable food security in both developed and developing regions.


The mission of AgMIP is to significantly improve agricultural models and scientific and technological capabilities for assessing impacts of climate variability and change and other driving forces on agriculture, food security, and poverty at local to global scales. To enable this mission, the goal is to create a next-generation knowledge platform for agricultural modeling worldwide.

Specific AgMIP objectives are to:

  • Incorporate state-of-the-art climate, crop, and agricultural economic model improvements into coordinated regional and global assessments of future climate impacts.
  • Perform multi-model integrated regional and global assessments of technology and policy options for increasing food security and adapting to current and future climate risks.
  • Utilize multiple models, scenarios, locations, crops and participants to explore uncertainty in climate and agricultural productivity and the effects of data and methodological choices.
  • Collaborate with regional experts in agronomy, soils, animal sciences, economics, and climate to build a strong basis for applied simulations addressing key climate-related questions.
  • Improve the scientific and adaptive capacity in the major agricultural regions in the developing and developed world.
  • Improve agricultural models based on their intercomparison and evaluation using high-quality regional and global datasets and best scientific practices, and document improvements for use in integrated assessments.
  • Develop frameworks to identify and evaluate promising adaptation technologies and policies and to prioritize strategies.
  • To achieve its objectives, AgMIP links strongly to major on-going efforts with public and private partners

Overview of AgMIP

Central to all AgMIP activities are models of agricultural systems, including crops, livestock, and economics. The activities include intercomparison of multiple agricultural models, evaluation and model improvement, development of improved methodologies for integrated assessments of impacts and adaptation, and the performance of integrated assessments at local to regional to global scales.

The AgMIP community collaborates in the comparison and improvement of agricultural models and develops ways in which they can be used to evaluate likely changes in crop production and economic conditions under current and future climate, farming, and societal conditions. Analyses of the agricultural impacts of climate variability and climate change, and of adaptation options require a trans-disciplinary effort to consistently link state-of-the-art climate scenarios to agricultural systems models.

AgMIP accomplishes its mission through collaborative scientific research and coordinated assessments, with outcomes including peer-reviewed publications, reports to policymakers, interdisciplinary training on multi-model approaches, web-based information and tools, and regional and global workshops and conferences. One of AgMIP’s aims is to provide a state-of-the-art knowledge platform – a truly global public good – to project future food security under changing climatic, technological, and societal conditions and to develop and test adaptation strategies in both developing and developed countries.

The community-driven approach has resulted in unprecedented gains by scientists in the advancement of agricultural systems modeling and access to effective methodologies for anticipating likely future scenarios of food availability. AgMIP is dedicated to enabling scientists in vulnerable regions, especially in the developing countries, to participate in the research processes by which such gains are made.

AgMIP is a international partnership program anchored in the United States Department of Agriculture (USDA) and implemented collaboratively with a suite of insightful and committed donors, national and regional partner programs, and members.

AgMIP’s Role in Ensuring Future Food Security

Agriculture is one of the important sectors most vulnerable to the impacts of climate change. This is due both to direct impacts on agricultural productivity and to indirect impacts such as changes in water availability, pests and diseases, and land use. Climate change is projected to reduce global agricultural production and increase its annual variation, leading to an intensification of the risks of hunger and malnutrition. The 4th Assessment of the Intergovernmental Panel on Climate Change (IPCC) confirmed that many of these impacts are likely to be felt severely in developing countries, where even a slight warming is projected to decrease yields in seasonally dry and low-latitude regions (IPCC, 2007).

This has significant implications for both food security and economic growth in many developing countries, where the majority of the poor are projected to continue to live in rural areas until 2040. Most depend on agriculture for their livelihoods, directly or indirectly. Rural farming communities are directly dependent on weather conditions for cultivation, so their capacity to manage climate-related risks is a high priority. There is an expanding evidence base underpinning the need for strengthened climate risk management and climate resilience in the face of increasing impacts of climate variability on the economic performance and livelihoods of the poor. Climate pressures will lead to shifts in patterns of farm household behavior in response to shocks. Families can find themselves introducing changes in diet preferences and facing more malnutrition and exposure to infectious diseases. These impacts of climate change are not solely projected to affect developing countries; climate change will impact agricultural regions in Europe, North America, South America, and Australia, as well.

Disruptions in major-producing countries will have an impact on world food supplies because of the international trade in agricultural production and could lead to broader food insecurity and conflicts that can have global implications. Negative impacts on agriculture in these areas are also likely to lead to impacts on economic growth and poverty reduction. Recent empirical evidence suggests that compared to growth in other sectors, growth in the agricultural sector generates welfare gains that are much stronger for the poorest parts of the population. Cross-country econometric work reported in the 2008 World Development Report shows that a 1% gain in GDP originating in agriculture generates a 6% increase in overall growth for the poorest 10% of the population. GDP growth originating in non-agricultural sectors generates zero growth for the poorest 10% of the population.

AgMIP is centrally positioned in the critical area of providing the dynamic agricultural models which enable developing and developed countries to understand the impacts of climate variability and change on their agriculture sectors, to identify appropriate adaptation options, and to inform investment decisions. The use of a suite of agricultural models embedded in a state-of-the-art technological system enables identification of probable impacts and interactions regionally and globally, strategic adaptation planning, and evaluation of technology investments. Significantly improved agricultural models also offer the means for testing the interactive implications of different adaptation and mitigation responses and for prioritizing critical areas for new research, e.g., novel crop types for sustainable intensification.

AgMIP Structure and Governance

As a global research program, AgMIP operates as an alliance among donors and partners. Donors provide financial support for contractually agreed-upon outputs and outcomes. National and regional partners are autonomous programs, operating at country or regional scales that contribute in specific ways to AgMIP initiatives, as defined by Agreement. AgMIP is flexible in its rendering of Agreements, with Inter-Governmental Agreement (e.g. MOUs) established through AgMIP’s USDA host; Institutional Agreement with an AgMIP Principal Investigator (PI) Institution or Letter Agreement with the PIs themselves. Agreements are maintained at the signing institution and/or at the Office of AgMIP International Coordination.

AgMIP also includes individual members who are interested in engaging in AgMIP activities and abide by the AgMIP Standards of Conduct. Individuals belonging to an AgMIP partner program, established by Agreement, are automatically recognized as individual members of AgMIP who agree to abide by the AgMIP Standards of Conduct.

AgMIP’s Steering Council guides the organization, ensures its scientific integrity through review processes and exercise of budgetary expertise, establishes policies that apply throughout the broader organization, and facilitates a high level of cooperation across the entire organization. To ensure a balance of scientific perspectives, the Steering Council is composed of donors, partners, and members, with at least 50% of the council comprised by representatives of AgMIP partners and members. The AgMIP Steering Council will develop and maintain a set of Bylaws that define its activities for guiding AgMIP and ensuring that it adheres to agreed Standards of Conduct.

Terms of reference for the selection and responsibilities for AgMIP Leaders will be developed by the Steering Council, in conjunction with the International Coordination Office. Potential criteria for selection of AgMIP Leaders include expertise, experience, suitability for advancing the mission, and the support of their institutions in serving in this capacity, with additional criteria at the discretion of the Steering Council. Current institutions supporting AgMIP Leaders include USDA-ARS, NASA-GISS/Columbia University, University of Florida and Oregon State University. Additional leadership roles are defined as needed to carry out AgMIP objectives.


AgMIP donors are entities that wish to further the evolving mission, goals, and activities of AgMIP and who agree with the principles and practices that AgMIP observes (e.g., AgMIP Standards of Conduct, see also below). Donors may be governmental or non-governmental organizations, foundations, companies, private individuals, and so forth. Donors may award funds in support of AgMIP through USDA-ARS Office of International Research Programs (OIRP), the Columbia University-based Office for International and Science Coordination, the AgMIP Leader institutions, or the AgMIP partners.


AgMIP’s partners are research programs, each having its own leaders and management structure and each being responsible for its activities, work products, and finances; e.g., they may be research organizations in individual countries or in groups of countries. AgMIP partners may establish committees or task forces to focus on particular scientific topics of interest to their members. They may also be asked to serve on AgMIP teams that set practice (e.g., for AgMIP publications, outreach, etc. to comply with AgMIP Standards of Conduct). All AgMIP partners agree to contribute to, and to comply with, policies established by the AgMIP Steering Council in exchange for Agreements that allow them to use the AgMIP name and receive other benefits from AgMIP, both tangible (e.g., acknowledgement of partnership status and institutional link on the AgMIP website; access to, dedicated collaboration pages) and intangible (e.g., access to AgMIP’s international network, association with the AgMIP, which is respected in the scientific community). AgMIP-Global and its Agreement-designated Partners will periodically undertake coordinated country, regional and global assessments based on mutually agreed-upon protocols.

AgMIP recognizes the importance of cooperation with other global and regional projects and initiatives that are currently in existence or that may be formed in the future. AgMIP policy is to seek partnerships with those entities that would be in the best interest of the AgMIP community of science. The goal is to minimize any real or perceived duplication of effort, and maximize outputs targeted by AgMIP, including agricultural model improvement efforts, initiatives for advancing scientific methods for development, evaluation, and application of agricultural models and assessment methodologies. A key AgMIP activity is the performance of multi-model integrated regional and global assessments of climate change impacts and assessment of technology and policy options for increasing food security and adapting to climate risks. AgMIP partners may also be private-sector organizations. Agreements will be established as needed to facilitate the partnerships.

AgMIP Standards of Conduct

The goal of the AgMIP Standards of Conduct is to ensure that AgMIP leaders, members, partners, and users of AgMIP’s scientific results are aware of the ethical principles guiding the organization’s structure and its adherence to rigorous, peer‐reviewed scientific investigation and evidence‐based outputs. The Standards are comprised of Principles that are maintained and updated by the Steering Council, in conjunction with the Office of International Coordination. The Standards of Conduct will be maintained at the AgMIP web site

The following principles provide a framework to guide ethical decision-making for AgMIP and to all of its partners and members.
