ABSTRACT: The target of the Goal 7 of Millennium Development Goals (MDG) is to halve by 2015 the number of people without sustainable access to safe drinking water and basic sanitation. The last few years have witnessed a relevant increase in the international concern towards water sector in developing countries, and an investment increase is envisaged for the next decade. In view of increased investments, monitoring efforts are required for the sake of efficiency and sound decision making in the water and sanitation sector. Available methodologies for measuring water poverty and water access show some drawbacks when applied to practical tracking of the water sector performance. A case is made in this chapter for the adoption of EASSY (Easy to get at local level, Accurately defined, Standard and internationally applicable, Scalable at all administrative levels, Yearly updatable) variables locally collected for monitoring water and sanitation sector. Implementing EASSY indicators will certainly require a proper definition from the scientific community and academia, the involvement of donors and civil society, and government willingness to implement measures to collect them.
