CIMMYT

CIMMYT. The International Maize and Wheat Improvement Center is a global research-for-development organization dedicated to improving livelihoods through maize and wheat science. It is a member of the CGIAR consortium and works with hundreds of partners worldwide to increase food security, enhance crop productivity, and promote sustainable farming practices. Headquartered near Mexico City, its work spans over 100 countries, focusing on breeding resilient crops, developing innovative agronomic systems, and building capacity among farmers and national agricultural programs.

History

The origins trace back to the mid-20th century collaborative programs between the Rockefeller Foundation and the Government of Mexico, notably the Mexican Agricultural Program which employed scientist Norman Borlaug. Borlaug's pioneering work on semi-dwarf, high-yielding wheat varieties sparked the Green Revolution, dramatically boosting grain production in regions like South Asia. In 1966, this successful wheat-breeding initiative was formally institutionalized with support from the Rockefeller Foundation, establishing its first headquarters at Chapingo Autonomous University. The organization expanded its mandate to include maize, formally adopting its current name and later becoming a founding member of the Consultative Group on International Agricultural Research in 1971. Over decades, it has evolved from a primary focus on varietal development to addressing complex challenges like climate change and natural resource management.

Research and development

Core scientific work focuses on the genetic improvement of maize and wheat through conventional and advanced breeding techniques, including molecular marker-assisted selection and genomic selection. Researchers develop varieties with enhanced traits such as drought tolerance, resistance to diseases like wheat rust and maize lethal necrosis, and improved nutritional quality, including biofortified zinc and iron-enriched wheat. Complementary agronomic research promotes conservation agriculture practices, such as reduced tillage and residue management, to improve soil health and water efficiency. The center maintains one of the world's largest and most diverse seed banks, the CIMMYT Germplasm Bank, which conserves over 150,000 unique seed collections of maize and wheat and their wild relatives, serving as a vital resource for global breeding programs.

Impact and outreach

Improved varieties and farming practices have been adopted across the Global South, from the wheat fields of the Indo-Gangetic Plain to maize farms in Sub-Saharan Africa. It is estimated that over 50% of the world's wheat area and 25% of maize area in developing countries are sown to varieties derived from its research. The organization conducts extensive training and capacity-building programs, partnering with national agricultural research systems, non-governmental organizations, and the private sector. Through initiatives like the MasAgro project in Mexico and the CSISA project in South Asia, it facilitates knowledge transfer and the development of local innovation networks to help millions of smallholder farmers increase yields and resilience.

Organizational structure

Governed by an international Board of Trustees, the center operates under the Director General, with research programs organized around strategic crop and systems-based platforms. It maintains major research stations in Mexico, including the principal campus in Texcoco and the El Batán experimental station, and has regional offices and hubs in key locations such as Nairobi, Hyderabad, and Dhaka. As part of the CGIAR system, it collaborates closely with other centers like the International Rice Research Institute and the International Center for Agricultural Research in the Dry Areas. Funding is provided by a consortium of public and private donors, including national governments, the World Bank, the Bill & Melinda Gates Foundation, and the United States Agency for International Development.

Key achievements and recognition

The development of high-yielding, semi-dwarf wheat varieties by Norman Borlaug, which formed the basis of the Green Revolution, earned Borlaug the Nobel Peace Prize in 1970. Subsequent work has produced landmark varieties like the drought-tolerant wheat 'Borlaug 100' and nutritionally enhanced maize 'Quality Protein Maize'. The center's scientists have received numerous accolades, including the World Food Prize awarded to Sanjaya Rajaram and the Japan Prize for work on sustainable agriculture. Its germplasm bank and global breeding networks are recognized as essential international public goods, contributing directly to Sustainable Development Goals related to zero hunger and climate action.
