Abstract:
The quality of surface water has noticeably improved in recent decades in many parts of the developed world, but is being challenged as economic growth, intensification of land use often combined with demographic or climate change lead to widespread and severe degradation. The need to reverse this development is reflected in the 2030 Agenda for Sustainable Development, both as a dedicated goal on water and as an integral element of the objectives in other sectors. The report ‘A Snapshot of the World’s Water Quality – Towards a global assessment’ summarizes key findings of the pre-study for a World Water Quality Assessment: (i) water pollution has worsened since the 1990s in many rivers in Latin America, Africa and Asia; (ii) the majority of rivers are still in good condition, and there are great opportunities for short-cutting further pollution and restoring the rivers that are polluted; (iii) monitoring and assessment are essential for understanding the intensity and scope of the global water quality challenge, yet data coverage is inadequate. The methodology developed offers a baseline to measure progress, a framework for global assessment and a pathway towards sustainable solutions that will deliver on that agenda. With the support from UN Water and the many contributing authors, this report will help bridge the gap between water quality, the inclusive green economy and the interlinked issues of sustainable development.
