The Dominican Surfing Federation has launched a sustainability program for Playa Bahoruco, a local top-class surf spot.

The main goal is to cultivate a self-sustainable community for the maintenance and preservation of the beach, for the benefit of its ecosystem, and to strengthen the community and its profile as a naturalistic, tourist and sporting destination.

With training sessions to be conducted regularly throughout 2012, the first daylong meeting included theoretical training and a beach clean-up, and integrated youth from fourteen to twenty-three years of age, from the beaches of Bahoruco, Arroyo, Juan Esteban and La Cienega.
