The UN-Water Global Analysis and Assessment of Sanitation and Drinking-Water (GLAAS) 2022 report compiles new data on drinking-water, sanitation and hygiene (WASH) from 121 countries and territories and 23 external support agencies (ESAs). It serves as a global reference to inform commitments, priority-setting and actions during the second half of the 2030 Agenda for Sustainable Development and for the 2023 Conference for the Midterm Comprehensive Review of Implementation of the United Nations Decade for Action on Water and Sanitation (2018–2028) (UN 2023 Water Conference). The report also highlights opportunities to accelerate progress in key WASH areas that positively affect the quality and sustainability of WASH services and delivery, pandemic preparedness and resilience to climate change.
