Comarapa, in the Santa Cruz Department, is Bolivia's leading municipal authority for incentive based watershed protection. In 2007 a municipal ordinance introduced a tariff (15 percent increase for water use, amounting to roughly USD$0.35 per month) for hydrological services. This tariff has so far been used to acquire key areas for hydrological service provision, to protect the upper watershed and drinking water sources, and to make compensation packages (bee boxes, fruit tree seedlings) under a Reciprocal Watershed Agreement (or ARA in Spanish) model. Local government and the irrigators association (and, minimally Fundación Natura Bolivia), also contribute to the Water Fund. The fund is administered by Caballero Public Services Cooperative Ltd. In 2009 the Comarapa Irrigators Association also joined the program, who pay $1.40 per hectare/year, which increased funds to a total of about $30,000 annually. Since inception, the program has spread to other watersheds in the municipality (San Isidro and San Juan del Potrero) and in 2012 the program was incorporated into a new Municipal Environmental Reciprocity Fund (FRAM in its Spanish acronym) incorporating the Puercos, Oconi and Ichilo watersheds.
