The recipient of the 2012 World Food Prize award, Daniel Hillel, discussed challenges facing agriculture during a recent speech in Lincoln, Nebraska.
The biggest challenge, Hillel says, is producing more food for a growing population without causing undue harm to the environment and natural resources. He says it is imperative that we adopt more efficient and sustainable agricultural practices.
A pioneer in micro-irrigation for crops in arid regions, Hillel has in recent years shifted his focus to climate change.
Here are some excerpts from his Lincoln speech.
