Introduction to theWorld Water Quality Assessmentand to the agenda of the day
About the assessment • UN-Water, led by UNEP • Initial funding: Norway, UN-Water, GEMS/Water • Initial scientific partners: Helmholtz-Centre Environmental Research-UFZ, Center for Environmental Systems Research,University of Kassel • Key partner: GEMS/Water • Global coverage, with focus on developing countries • Freshwater, inland waters (running waters and lakes) • Two-stage assessment: Stage 1 (2 years); started in June 2013, using existing models and data
Assessment goals at stage 1 • Review the state of water quality in rivers and lakes/reservoirs • Identify current hot spot areas of degraded water quality(use UNEP water quality guidelines initiative as benchmark) • Identify types, intensity and sources of water pollution • Identify potential impacts relating to human health and food security • First assessment of freshwater fishery link to food security(linking water quality with ecosystem services) • Identify main water quality data gaps • Policy options in perspective (precautionary, abatement, restoration)
Our top down and bottom-up approach Global perspective – Top down WaterGAP3 modeling framework (global 5’ grid) Modeldrivenanalysis WQ status BOD, FC, TDS, TN/TP Hot spot Datadriven analysis Advisory Committee v GEMS/Water, databases, literature review Local/Regional perspective – Bottom up
What are we going to do today? • “Progress reports”: • Current data basis, data collection and data driven analysis • Large-scale water quality modelling - Hot spots and causes of water pollution • Concept of the overall assessment and next steps • Technical issues (e.g. dash board) • Feedback and AC recommendations
What are we going to do today? • Special discussion points: • Strengthening links and cooperation with GEMSand UNEP Live, … • Involvement of UN Agencies (FAO, WMO, WHO, UNEP,UNESCO, …) • Next steps, …
