  1. Crop Science in Food Security Brian Diers

  2. Outline • Role of Crop Science in food security • Crop Sciences Department research on increasing crop production • USAID soybean project in Africa

  3. Global Crop Production Needs to Double by 2050 • Yield increases of 2.4% / year needed to meet demand without putting more land in production Current 1.6% 1.0% 0.9%1.3% Ray DK, Mueller ND, West PC, Foley JA (2013) Yield Trends Are Insufficient to Double Global Crop Production by 2050. PLoS ONE 8(6): e66428. doi:10.1371/journal.pone.0066428 http://www.plosone.org/article/info:doi/10.1371/journal.pone.0066428

  5. US yield increases are approximately 1% / Year

  6. Crop Sciences Department is Focused on the Crop Production Challenge • Diverse portfolio of research • Breeding/genetics • Molecular biology/genomics • Agronomy • Plant protection

  7. Crop Sciences Department Soybean Breeding and Genetics Research • Improving soybean with a focus on yield and disease resistance. • Releasing nonGMO varieties. • Identifying useful diversity in USDA soybean germplasm collection (Randall Nelson, curator).

  8. Soybean Innovation Lab Breeding Research in Africa

  9. Why Soybean in Africa? • There is a protein deficiency in Africa and soybean produces more protein / area of farmland compared to any crop or livestock system. • Soybean is a relatively low input crop and doesn’t require nitrogen fertilizer. • Better varieties and production practices needed to improve yield and make the crop profitable for growers.

  10. Soybean Yields are Low in Africa • African soybean yields are similar to the USA in the 1930s. Yield kg/ha Year

  11. Participants in Breeding Effort • USA (60+ years of soybean breeding experience) • Randy Nelson – USDA-ARS and University of Illinois • Brian Diers – University of Illinois • Africa (little experience in breeding soybean) • HeshamAgrama – IITA breeder Malawi and Zambia • Nicholas Denwar – SARI breeder, Ghana • AbushTesfaye – Jimma Agricultural Research Center

  12. Soybean Breeding Programs • SIL providing: • Basic equipment for breeding • Threshers, planters, vehicles, crossing forceps, scales • Germplasm • Technical expertise

  13. Conclusions • Crop Science has a critical role in food security • Crop yields are increasing, but not fast enough to meet growing demands • Crop Sciences Department research portfolio is focused on improving sustainable crop production • The Soybean Innovation Lab is working in increase soybean production in Africa

  14. Need for Food Production Increase • Maize (corn), rice, wheat, and soybean produce nearly 2/3 of global agricultural calories. • We need increase of 2.4% per year (non-compounding) for these crops globally. • Current global rates are 1.6% (maize), 1.0% (rice), 0.9% (wheat) and 1.3% (soybean). Ray DK, Mueller ND, West PC, Foley JA (2013) Yield Trends Are Insufficient to Double Global Crop Production by 2050. PLoS ONE 8(6): e66428. doi:10.1371/journal.pone.0066428 http://www.plosone.org/article/info:doi/10.1371/journal.pone.0066428

  15. Need for Crop Production Increase • Crop production is needs to double by 2050 be meet growing demands • How to meet the demand? • Increase area under production • Increase output of land in production

  16. Challenges • Breeding programs are small • Breeders have staff lack experience with the crop • Limited by the number of plots that can be planted and threshed by hand threshed • Limited by what is viewed as possible
