LINCOLN, Neb. (AP) — The authors of a book about the future of farming will talk in Lincoln about how organic farming and genetic research can help feed the world.

Pam Ronald and her husband, Raoul Adamchak, will be the featured speakers at the University of Nebraska-Lincoln's Heuermann Lecture on Tuesday.

They wrote "Tomorrow's Table: Organic Farming, Genetics and the Future of Food."

The couple works at the University of California-Davis campus. Ronald does genetic research on plants, and Adamchak teaches organic agriculture and runs a 5-acre student farm.

UNL Vice Chancellor Ronnie Green says the speech will be welcome on campus because the world is struggling to figure out how to feed everyone without damaging the environment.
