Sustainable Intensification of Maize-Legume Systems for Food Security in Eastern and Southern Africa
The Sustainable Intensification of Maize-Legume Systems for Food Security in East Asia (SIMLESA) program is a collaboration between the national agricultural systems of Ethiopia, Kenya, Malawi, Mozambique, and Tanzania, and CIMMYT, the International Center for Research in the Semi-Arid Tropics, the Association for Strengthening Agricultural Research in Eastern and Central Africa, the Queensland Alliance for Agriculture and Food Innovation – University of Queensland, Murdoch University, the Agricultural Research Council (ARC), and the Australian government via the Australian Center for International Agricultural Research (ACIAR). Through participatory research and development with farmers, extension agencies, non-governmental organizations, universities, and agribusinesses along the value chain, the program aims to improve maize and legume productivity by 30 percent and to reduce the expected downside yield risk by 30 percent on approximately 500,000 farms within 10 years.
The focal countries of program research are Australia, Botswana, Burundi, Ethiopia, Kenya, Malawi, Mozambique, Tanzania, South Sudan, Uganda, Rwanda, Zambia and Zimbabwe. Why Australia? Given the emerging problem of climate change (for example, an International Institute for Environment and Development) model suggests that Tanzania’s gross domestic product will decline by 1 percent annually by 2030), existing capacity in Australia will be invaluable to helping this region with needed adaptations. Australia could benefit from the drought tolerant and disease resistant maize germplasm developed by CIMMYT for Africa. Africa could, in turn, benefit from advanced GxE analysis techniques applied by Australian breeders which could also initiate more systematic germplasm exchange between CIMMYT and Australia. Further benefits could come from the exchange of legumes and Rhizobium strains.
