   Cassman left UC Davis after being named director of the International Rice Institute in the Philippines. He now teaches agriculture classes at the University of Nebraska where he continues to conduct research in rice, wheat and corn.
   
   His noon talk focused on the future of feeding the world's population, which emphasized the need to rethink how land resources are used to sustain the world's food supplies.

   Last year, a University of Nebraska agronomist, Ken Cassman, doing research with other agricultural scientists at the International Rice Research Institute in the Philippines, provided some of the first evidence that global warming could hurt food production.
   
   This 11-year field study found that rice yields decrease 10 percent for every 1.8-degree Fahrenheit increase in nighttime temperatures when solar radiation and temperature are the only factors limiting yields, Cassman said.
   
   "These findings suggest the yield potential ceiling could decrease if global temperatures continue to rise," he said.
   
   Yields for rice, a leading food crop in much of the world, have leveled off in several major rice-producing regions. With rice yields already close to maximum potential in these regions, there's little room for improvement. Global warming might lower that potential, said Cassman, a scientist in the university's Institute of Agriculture and Natural Resources.
   
   This research has implications for Nebraska where major crops, including corn, soybeans and wheat, also are sensitive to high temperatures during the critical grain development period.
   
   "Meeting world food demand in the next 30 to 40 years is going to be a challenge without global warming," Cassman said.
