The Global Estuaries Monitoring Programme

The United Nations Decade of Ocean Science for Sustainable Development (2021-2030)

Endorsed Ocean Decade Action

The Global Estuaries Monitoring (GEM) Programme is co-designed by partners and stakeholders with a view to developing a global network to monitor environmental contaminants (e.g. pharmaceutical residues, emerging pollutants of concern, micro-plastics, pathogens etc.) in major urbanised estuaries worldwide.


The Programme will develop standard sampling and analysis methods with training opportunities to build capacity for global estuaries monitoring. With about 100 countries expected to join the Programme, its results will reveal the pollution situation around the globe, identify the estuaries that require attention and improvement, recommend priority contaminants for control, and promote best practices to combat the pollution problems and thereby creating cleaner estuaries.
