Q. and A.: Farming for an Uncertain Future
For his work, Mr. Jackson was named a Pew Conservation Scholar in 1990 and a MacArthur Fellow in 1992. In 2000 he received a Right Livelihood Award, which goes to honorees “working on practical and exemplary solutions to the most urgent challenges facing the world today.”
Among those challenges is feeding a global population that is expected to reach nine billion people by midcentury. The Land, as devotees call the institute, is developing perennial crops like Kernza , a wheatgrass with a substantial root structure that would alleviate the need for yearly planting and thus help to replenish the soil and reduce erosion while guaranteeing an annual food crop.
On Friday, the Land Institute kicks off its 34th annual Prairie Festival , a weekend of scientific lectures that will also include a barn dance, bonfire and a celebration of the 35th anniversary of the publication of Wendell Berry’s seminal book, “The Unsettling of America: Culture and Agriculture.

The Free Energy Future That Motivates Me
This would be a paradigm shift compared to how civilization views energy resources today. Importantly, draconian, economy-crushing policies such as carbon taxes could be thrown out the window. Right now, governments around the world are using ...
