Worker takes a break in heat of the cane fields. 2003.   Worker takes a break in heat of the cane fields. In 2003 I had the opportunity of photographing the burning and harvesting of the sugar cane on the then Government owned Caymanas Estate. Using outdated equipment and sugar largely cut by hand in the searing heat, workers make up a substantial number of voters. So successive Jamaican governments have made every effort to keep the industry going. Today, the island economy relies mostly on agriculture and tourism industries. The sugar industry is the oldest continually operating industry in Jamaica, generating the third largest foreign exchange for the island.
