It’s a fascinating conclusion drawn by the authors of a recent study by the Kamehameha Schools, the University of Hawaii at Manoa and the U.S. Geological Survey: The old ways of agriculture might have been the best.

At the very least, indigenous methods of cultivation have been found to be resilient to even the most severe climate scenarios, such as coastal flooding and drought, according to the study to be published in March in Nature Sustainability.

Hawaii had better hope that its past might hold the answers. So far food sustainability has eluded the experts of today.

An open runway for Southwest

Talk about unexpected turbulence. Southwest Airlines finally received federal approval on Wednesday to fly to Hawaii from California, some two years after announcing it would. In addition to expected regulatory buffeting, Southwest also hit unanticipated headwinds when the 35-day partial government shutdown stalled the airline’s certification process; then an ongoing dispute with its mechanics union flared this month, causing hundreds of mainland flights to be canceled.

Being cleared for Hawaii takeoff, then, is great news for Southwest. Let’s hope that also holds true for Hawaii flyers, as ticket prices get unveiled.
