  2. EO4SDG 6.6.1/6.3.2 • Monitoring changes in the quality of surface waters (e.g., lakes, reservoirs, water supplies, estuaries) • EO is capable of providing spatially and temporally consistent measurements of materials that impact color of water like • Chlorophyll-a • Total suspended sediment • EO-derived estimates relate to the health/condition of a waterbody Chlorophyll-a @GEOSEC2025 www.earthobservations.org

  3. NASA’s Applied Sciences and SDG 6.6.1/6.3.2 • Outreach activities in coordination with UNEP • Introduce water quality monitoring through EO • Engage countries in validating EO products Latin America (Bogota, Colombia) – April 2018  Africa/Asia (Bellagio, Italy) – Nov 2018   • Colombia, Peru, Venezuela, Bolivia, Panama, • Costa Rica , Ecuador Zambia, Senegal, Uganda, Egypt, Mongolia, Colombia @GEOSEC2025 www.earthobservations.org

  5. NASA’s Development of a Tool for Monitoring SDG 6.6.1/6.3.2 • STREAM: Satellite-based analysis Tool for Rapid Evaluation of Aquatic environMents Allows Easy-access, Visualization, and Analyses of EO for SDG Reporting

  6. How Countries Can Contribute? • Coordinate your field monitoring activities with satellite overpasses Lake

  7. Key Challenges • Identify countries’ relevant agency/organizations and proactive points of contact • Demonstrate the utility of products • Capacity building • Convey the limitations of EO and product uncertainties • How to define a baseline condition
