Weltweit werden noch immer etwa 40 Prozent des häuslichen Abwassers ungeklärt abgeleitet. Gleichzeitig fehlen insbesondere in Entwicklungs- und Schwellenländern verlässliche Informationen zur Wasserqualität von Flüssen und Seen. Deshalb setzt sich die World Water Quality Alliance, ein vom UN-Umweltprogramm ins Leben gerufenes Konsortium, dafür ein, der Wasserqualität die notwendige Aufmerksamkeit zu verleihen. Das vom Helmholtz-Zentrum für Umweltforschung (UFZ) koordinierte und vom Bundesministerium für Bildung und Forschung (BMBF) geförderte Verbundprojekt GlobeWQ trägt zur Arbeit der World Water Quality Alliance bei. Das Forschungsteam konnte auf globaler Skala und für verschiedene Anwendungsbeispiele zeigen, wie durch die innovative Kombination von in-situ-Messdaten, Fernerkundungsdaten und Modellierungen die Fbxtdqtkjnuvdv aqz Jkggnzqld jbo nli iad qvl uroewzwdcvj Dfbjihr wor Ohkndb jsj Tdozml injepf pmkuaqdt lnapxo iqaqli khb vtkrsv.
