Then, between August and October 2016, an external review and pilot tests were conducted, and the methodologies were readjusted in February 2017 to better assist countries in collecting data for establishing an integrated global baseline for SDG 6—in time for an in-depth review during the 2018 High-level Political Forum on Sustainable Development. First, it is important to identify the interlinkages, synergies and trade-offs among the various targets within SDG 6 as well as across all 17 SDGs. Then these interlinkages need to be compared with the institutional and budgetary structures across the national government to devise institutional reform that can enhance efficiency and effectiveness of the institutional architecture of the 17 SDGs. National targets and local SDG road maps can be developed for the effective mobilization of resources, based on national circumstances.
