The prospects of the domestic water equity indicators in Indonesia: a review

Despite the major progress achieved by the domestic water supply sector since the commencement of the Millennium Development Goals (MDGs), there is still a concern that access towards water does not distribute evenly among citizens in different geographical areas or diverse economic groups. The Sustainable Development Goals (SDGs) strive for a universal water target that highlights the sustainable access to safe and affordable water supply for all. Hence, the ensuing challenge is how to comprehensively report the progress of achieving water equity in relation to the SDGs target. This paper reviews the current research and policy papers on equity metrics in the water supply sector. This study has identified that water inequity may manifest in the variations of the level of access, the dimensions of access, and the impacts of poor water supply-spatially, socially, economically, or the combination thereof. This paper also presents challenges related to the application of equity measurements in the context of Indonesia. The results will be useful in designing appropriate tool to inform decision making in water sector policy.
