These are problems that will be addressed by scientists and policymakers at the Climate-Smart Agriculture Global Science Conference at UC Davis this week.
For the story, Ortiz interviewed Eduardo Blumwald, professor in the Department of Plant Sciences at UC Davis, one of the conference speakers. Blumwald believes many of the problems of world food production can be addressed with genetically modified organisms.
"There is no other alternative," he said. "Our population is increasing. We'll be at 9 billion people by 2050, and food security is a big problem."
Eric Holt-Giménez, executive director of Food First, told the reporter he believes genetically modified crops are no silver bullet solution for salty and thirsty soil or for pest control.
"Building resilience into the ecosystem is the only way to address the problem," he said.
Alan McHughen, UC Cooperative Extension specialist in the Department of Botany and Plant Sciences at UC Riverside, said he is a proponent of the judicious use of GMO technology.
"We have to investigate it – it has to be treated with respect," he said. "There will be some products that come through that we don't want to be commercialized, and then there will be others that should be commercialized more rapidly."
