Project Seeks to Cut Maize Production Losses of US$ 72 Million

Maize is a major food crop in Africa, especially in the eastern and southern regions of the continent. For many, it is the main dietary staple, as evidenced by annual consumption levels of 79 kg per capita in the region and 125 kg per capita in Kenya. Threats to this food source endanger food security, and stem borers pose just such a threat in much of Africa. In Kenya alone, farmers report losing 15% of their maize harvest to stem borers, equivalent to 400,000 t of maize valued at US$ 72 million. Farmers in some areas have reported losses as high as 45%.

Such losses are significant in a country where maize must be imported to meet domestic demand. For individual farmers, many of whom live on less than US$ 1 per day, this destruction can be devastating. Insect pest infestations can decimate entire fields of maize and deprive families of a vital source of food and income.

To tackle this problem, the Insect Resistant Maize for Africa (IRMA) project was launched in 1999 by the International Maize and Wheat Improvement Center (CIMMYT) and the Kenya Agricultural Research Institute (KARI), with financial support from the Syngenta Foundation for Sustainable Agriculture.

The project is aimed at producing maize that is adapted to various Kenyan agroecological zones and is also resistant to key insect pests, primarily stem borers. Both conventional and biotechnology-based sources of resistance will be examined for their effectiveness against the borers. The project emphasizes public involvement and awareness through events such as its annual Stakeholders Meeting. Furthermore, major project objectives include environmental and socioeconomic impact studies, resistance management strategies, and project documentation. Based on the experiences and results generated in Kenya, appropriate technologies and varieties will be extended to other African nations.

Objectives of the IRMA Project

The general objectives are to:

• develop insect resistant maize varieties for the major Kenyan production systems and insect pests;
• establish procedures to provide insect resistant maize to resource- poor farmers in Kenya;
• assess the impact of insect resistant maize varieties in Kenyan agricultural systems;
• transfer technologies to and Kenya to develop, evaluate, disseminate, and monitor insect resistant maize varieties; and
• plan, monitor, and document project processes and achievements for dissemination to other developing countries.

Project Activities

The project engages in three groups of activities:

1. development of insect resistant maize,
2. development of effective dissemination and stewardship strategies, and
3. impacts assessment.

Development of insect resistant maize entails

• development of infrastructure in Kenya to screen maize plants for insect resistance;
• identification of genes that are active against Kenyan stem borers;
• identification of target maize germplasm for transformation and for backcrossing to source germplasm;
• development of transgenic-based insect resistant maize germplasm;
• backcrossing of maize adapted to Kenya with transformed germplasm; and
• development of high-yielding, improved, and adapted insect resistant maize germplasm.

Development of effective dissemination strategies for insect resistant maize in Kenya entails

• development of insect resistance management (IRM) strategies;
• acquisition of the required licenses and agreements to enable the technology to be used in farmers’ fields;
• full application of biosafety and bioethical standards and protocols;
• agronomic studies of insect resistant maize; and
• dissemination of insect resistant maize to farmers.

Impact assessment and socioeconomic analysis entails

• assessment of the demand for insect resistant maize varieties through studies of the different maize-based farming systems, a survey of farmers’ perceptions and preferences, and a survey of consumers’ preferences;
• assurance that the technology fits within the country’s institutional framework and an assessment of the implications and costs of intellectual property rights (IPR);
• assurance of the safety of the technology to the public through continuous dialogue with environmental groups, local research institutes, and private or public companies involved with seed production;
• assurance that the technology is acceptable to farmers (through farmer participatory research);
• comparisons of the costs of the new technology to its benefits at various levels, including the maize producer, the seed company, the consumer, and society as a whole; and
• impact assessment and cost-benefit analyses of the research.

Expected outputs of the project include

• maize inbreds, hybrids, and open-pollinated varieties that combine conventional and biotechnology-based insect resistance;
• protocols developed and KARI scientists trained in the development, evaluation, dissemination, and monitoring of insect resistant maize;
• economic analyses to determine farm-level profitability, farmers’ willingness to pay for the technology, and the overall private and public benefits of the technology;
• insect resistance management strategies;
• practical experience for KARI staff in biosafety and intellectual property rights procedures in Kenya; and
• documentation of experiences on development, dissemination, and impacts of gene-based resistant maize germplasm.

Target Germplasm: CML216 and other African maize inbreds and OPVs

Gene(s): cry1Ab, cry1Ba, cry1Ca and cry2Aa

Partner(s): Kenya Agricultural Research Center (KARI), Syngenta Foundation for Sustainable Development, The Rockefeller Foundation

Current Status: Stable, low-copy events of cry1Ab and cry1Ba produced and backcrossed into CML216. Biosafety greenhouse (BGH) established in KARI and seeds of the cry1Ab and cry1Ba events imported and growing in the BGH following approval by Kenya authorities. Quarantine field site established and being used for mock trials and training of local staff and farmers. Testing of Bt maize at the site is anticipated for 2005, pending regulatory approvals. Events of cry1Ca and cry2Aa being produced. Numerous experiments conducted or in-progress to determine effective insect resistance management strategies for Kenyan farmers. Environmental, food and feed safety aspects being investigated.
