KONSEP IMBAL JASA LINGKUNGAN UNTUK KEBERLANJUTAN SUMBERDAYA AIR DAS 1 CIDANAU

The Cidanau Watershed, the only swamp forest ecosystem available in Java Island, is an important source of raw water in Banten Province, especially for industrial areas and residents of Cilegon City. Although the Cidanau Watershed is a Nature Reserve, however, encroachment and deforestation have threatened the sustainability of water availability. The needs of the upstream communities who rely on natural resources and the need on water for the downstream communities require a satisfactory solution for both parties. Because each has particular interest, it is necessary to build a mutual relationship between the two. Implementing Payment for Environmental Service (PES) mechanism, a beneficial reciprocal relationship will establish between the downstream communities as water users and the upstream communities as the guarantor for sustainability of the upstream ecosystem as water catchment areas. The PES scheme has a positive impact on the improvement of biodiversity, ecological functions and socio-economics. The acceptance on appropriate value of water is measured by willingness to pay. The latter is a mutual agreement between service providers and the users. In order to guarantee the transparancy on the implementation of PES implementation then Institutional stakeholders consisted of farmer groups, non-government organizations and local governments is needed. This paper is aimed at describing lesson learned from the implementation of PES between PT Krakatau Titra Industri with upstream community of Cidanau watershed that was mediated by Forum Komunikasi DAS Cidanau.
