I found this an odd use of the term Caucasian

From today's Gleaner
Hundreds of Caucasians getting their hands and feet dirty from planting ginger in Jamaica was an unusual sight for sure. A few visitors also came from France, China, Japan, and Mexico to join in. One participant, Stephanie Newton, from North Idaho was so caught up in the experience that she took her three-month old baby, Rudie, along to the farm.

But more remarkable was the fact that the day's operation was directed by teenage students from the Knockalva Agricultural School in nearby Ramble. The Jamaican students are learning about the viability of farming as a lifelong career, and they flawlessly executed the ginger operation, taking advantage of the hands-on experience that this project provided. They quickly bonded with the visitors and brought the ginger-planting mission to completion ahead of the 5 p.m. scheduled target. The management of the newly minted farm was immediately turned over to present students and recent graduates of Knockolva, who will monitor the operation and share in the profits of the ginger project.
