Assessment of Current and Future Hydrological Conditions Using the GenRiverModel: evaluating the existing PES scheme in Cidanau watershed

* Ecological functions of watersheds, including hydrological functions, are directly linked to human well being; they respond to changes in land
cover, climate and engineering of the river flow and its buffering in wetlands,
* The Cidanau watershed in western Java (Banten province) provides water to downstream communities as well as companies. An industrial water supply company experimented with a payment scheme for watershed services, jointly with a multi stakeholder forum and local
governments.
* Initial focus of payment scheme was on increasing the tree density of existing agricultural systems in an area of 100 ha.
* We applied a hydrological model, GenRiver, to analyze the effectiveness of the existing scheme and some of its alternatives
