Feed the Future Innovation Lab for Collaborative Research on Sustainable Intensification

Adoption of sustainable intensification in dual-purpose millet – leguminous crops – livestock systems to improve food and nutritional security and natural resources management for rural smallholder farmers in Senegal

Lead Institution: Kansas State University

Summary: Senegal is facing a difficult food situation, and the gap between national production and the needs of an increasing population has continued to widen in recent years. Millet is one of the most important cereal crops in Senegal due to good adaptation to high temperatures, severe drought conditions and soil types in most regions of Senegal. Many varieties of millet have been used as grains and/or raw materials for fences or roofs of homes in rural areas in Senegal. The main objectives of this project are:
  1. To ensure food and nutritional security
  2. To establish resilient farming systems via a holistic approach for rural smallholder farmers, particularly women
  3. To improve nutritional and socioeconomic status in particular for women and children in six regions of Senegal: Louga, Diourbel, Kaffrine, Kedougou, Kolda and Sedhiou.

These objectives will be achieved by using sustainably intensified production and management practices of dual-purpose millet and leguminous crops (cowpea and groundnut) with small ruminant livestock (goats and sheep) integration. In Senegal, millet is primarily produced at the subsistence level and hand-processed by women and girls. Cowpea and groundnuts are very important nitrogen-fixing leguminous crops that can provide nitrogen to millet. These leguminous crops can also be used as fodder for livestock in Senegal. Thus, intercropping dual-purpose millet as grain and fodder into dual-purpose cowpea or groundnuts, as well as integrating these dual-purpose crops with livestock, will help improve food security, human nutrition, crop diversity, livestock performance, soil quality (carbon sequestration) via nutrient recycling from animal manure/crop residue, biodiversity, smallholder farmers' income (especially women), and further women's engagement in farming. Additionally, this type of system will impact resilient natural resource management of water, soil, nutrients and greenhouse gas mitigation in Senegal.   

 

2017 Progress Updates

  • Agronomic field trials of five pearl millet accessions (two local varieties and three new dual-purpose were initiated in Bambey, Nioro, and Sinthiou Maleme. Field days allowed local farmers the opportunity to see the tested varieties and to ask the millet breeder and project agronomists about growth characteristics and cultural management practices.

  • A sheep feeding trial was conducted using the dual-purpose millet varieties (see item (a)) at the University of Thies.

  • Chemical analysis of five millet varieties was conducted. It was found that two of the new dual-purpose varieties contained higher zinc and iron content than the traditional varieties. Bioavailability studies of zinc and iron will be conducted by Kansas State University in FY 2018.

  • Socioeconomists in Senegal and the U.S. finalized the baseline field surveys. Moving forward, subaward Co-PIs will work to identify barriers to adoption and to conduct an economic evaluation of the technology interventions in the project areas.
