The evidence as a result of monitoring the inputs and outputs provided by the UN-Water Global Analysis and Assessment of Sanitation and Drinking-Water (GLAAS), TrackFin and WHO/UNICEF Joint Monitoring Programme (JMP) helps to guide decision-makers at the local, national and global levels. The information provided by JMP, GLAAS and TrackFin is also a key component of measuring the success of the Sustainable Development Goals.

Water and sanitation monitoring and evidence facts

  • 94 countries and 23 external support agencies participated in the 2013/2014 GLAAS cycle.
  • Over 80% of 2013/2014 GLAAS respondent countries have approved national policies for sanitation and drinking-water.
  • Development aid commitments for water and sanitation have increased 30% to over US$ 10.9 billion in 2012, from US$ 8.3 billion in 2010.

Investments and the enabling environment

To improve access to safe water and sanitation, it is necessary to understand what actions countries and external support agencies are undertaking in the water, sanitation and hygiene (WASH) sector.

Economic benefits of investing in water and sanitation

Economic benefits of investing in water and sanitation are considerable: they include an overall estimated gain of 1.5% of global GDP and a US$ 4.3 return for every dollar invested in water and sanitation services, due to reduced health care costs for individuals and society, and greater productivity and involvement in the workplace through better access to facilities.

Water supply, sanitation and hygiene monitoring

The overall aim of the JMP is to report globally on the status of water supply and sanitation sector, and to support countries in improving their monitoring performance to enable better planning and management at the country level.
