Study: Maximizing Grain Yields won't meet future African needs

Meeting future cereal demands could depend on expanding responsible irrigation use to raise yield ceilings and stabilize cereal production, said Kindie Tesfaye, agronomist with the International Maize and Wheat Improvement Centre in Ethiopia. Recent analyses have documented regional aquifers that could become sources of sustainable irrigation, though the authors emphasized the importance of withdrawing only what can be replenished by rainfall and recharge.

New research from the University of Nebraska-Lincoln and its collaborators has found that sub-Saharan Africa will struggle to meet its 2050 grain demands even if it maximizes the yields of corn and four other cereal crops.
