A/67/270 data on certain issues is not accidental. Neglect often coincides with a low political profile. For example, in many countries, people living in informal settlements do not appear in the official statistics, even when they represent a high percentage of the population in major cities. In that regard, the Special Rapporteur calls for pushing the boundaries of what is currently perceived as measurable. A commitment to better and more accurate data collection as part of the global framework is essential to identifying and monitoring inequalities, a crucial step to making progress to end them. 23. As a final word on measures and monitoring, it must be noted that there are significant differences between the aim and purpose of indicators for human rights monitoring and indicators to be used in monitoring outcomes in the context of global development goals. In recent years there has been a greater effort to explore the use of indicators as human rights monitoring tools. Human rights monitoring indicators are designed to closely relate to specific legal norms. As such, they must reflect and effectively measure all elements of a right, including integration of cross-cutting human rights norms such as participation and accountability. Such indicators should be flexible enough to be contextually relevant. On the other hand, the call to integrate human rights elements into the post-2015 framework seeks to make monitoring these development goals rights-sensitive rather than transforming them into human rights monitoring tools. C. Water, sanitation and hygiene in the global development framework 24. Under the current structure, the target for water and sanitation comes under the broader environmental goal, which also includes protection of natural resources, reduction of biodiversity loss and improvement of the lives of slum dwellers. The post-2015 development agenda should dedicate a stand-alone goal to water, sanitation and hygiene, considering that access to these services plays a central role in social and economic development. 25. The lack of access to water, sanitation and hygiene has not only an environmental impact but also social and individual dimensions. From a human rights perspective, water and sanitation, just like food, are parts of the same fundamental right to an adequate standard of living. Their similarities with other sectors such as education and health warrant attention alongside goals in these areas to ensure visibility and prioritization. Member States should take a consistent approach to their commitment in the Rio+20 outcome document, in which water and sanitation were set as one of the priority areas for sustainable development (see General Assembly resolution 66/288, annex, para. 119). 26. The normative content of the right to water and sanitation defined in terms of availability, quality, acceptability, accessibility and affordability points to essential features to be considered in the definition of indicators and targets. The misalignment of the current framework, such as for instance, the omission of whether water sources counting towards the achievement of the target are of good quality, has shown that the Millennium Development Goals can greatly benefit from better and more sustainable impacts if human rights are mainstreamed. 27. Access to water and sanitation is not only a human rights entitlement but it also has an enormous impact on human health: it is central to the reduction of child mortality, malnutrition, neglected tropical diseases, opportunistic diseases for people living with HIV/AIDS, and a number of other health conditions.
