A/67/270 different forms and manifestations of inequalities in any meaningful and comprehensive way. 50. The challenge is to set such an overall goal on equality that does justice to its cross-cutting nature, relevance to all fields of development and different grounds and manifestations of inequalities. To address these challenges, the future development agenda could include an overall goal on achieving equality accompanied by targets for different sectors for reducing inequalities. Since it might not be necessary, feasible or advisable to relate all targets to all different grounds of discrimination, the pertaining indicators could focus on the dominant inequalities as relevant for different sectors relating to sex, disability, age, income/wealth, ethnicity, and geographic location, among other stratifiers. 34 The overall framework would have to ensure that all different types of inequalities are captured. Optionally, if indicators with ordinal values were selected, the different sectoral indicators could be combined for a composite score that would yield an overall measure of equality. IV. Goals, targets and indicators for water, sanitation and hygiene 51. One of the challenges for the post-2015 development agenda will be to improve the analysis of the different forms of discrimination in access to water and sanitation and to design an appropriate methodology to monitor them. In this context, the Special Rapporteur highlights some manifestations of discrimination to assist in the assessment of goals, targets and indicators to successfully monitor non-discrimination. Appreciating that there will be difficult decisions ahead as goals, targets and indicators are narrowed and culled, she suggests some key issues for a future development agenda. These cover a range of different considerations derived from international human rights law as well as general considerations of equity. These issues could also, mutatis mutandis, be applied outside the water, sanitation and hygiene sector — so as to ensure that equity and non-discrimination are also captured in other areas of development. 52. Based on these considerations, this section also puts forward some ideas on how to integrate these in the future development goals, targets and indicators framework. It describes proposals on the methodology needed to gather and analyse the data necessary to support monitoring progress towards these targets. The monitoring system currently used by the Joint Monitoring Programme relies chiefly on household surveys. This data set includes a wide variety of equity and equalityrelated variables, which are amenable to much more equality analysis than has been performed to date. Other data could be generated relatively easily with slight adaptations of the current data sources and the addition of other sources to complement household surveys. The Special Rapporteur encourages the Joint Monitoring Programme and other monitoring bodies to explore ways to supplement household survey data with additional sources. Some potential additional sources include data from water and sanitation providers (such as data about location of users, fees paid, areas where access is non-existent or minimal), administrative data (e.g., data about service levels, cut-offs and disconnections). Through her discussion with technical experts and data specialists, the Special Rapporteur has learned that these proposals are feasible and that better monitoring of the equality dimension of access to water and sanitation can be achieved with the required political will. __________________ 34 12-45653 Melamed, “Putting inequality”, p. 5 (see footnote 2 above). 15
