Monitoring water quality using EO: UNESCO World Water Quality Portal
Improving water quality worldwide is essential for the SDGs achievement. However, reliable data on water quality is scarce at the global, regional and national levels, especially in developing countries where monitoring networks and capacity are lacking. The use of innovative approaches such as Earth Observation (EO) and space technology can enhance water quality data at the global scale.
The UNESCO World Water Quality Portal, developed by UNESCO-IHP International Initiative on Water Quality (IIWQ), is a pioneering tool to monitor freshwater quality using satellite data. It aims at improving water quality monitoring at the global scale to support the SDGs implementation. The Portal provides data on five water quality indicators: turbidity, chlorophyll-a, Harmful Algal Blooms (HAB), organic absorption and surface temperature, which are essential for understanding the impact of climate and anthropogenic changes (i.e., urban areas, fertilizer use in agriculture, climate change, dams, etc.). Hence, it supports science-based policy-making.
The session showcases the use of UNESCO World Water Quality Portal for water quality monitoring in demonstration basins, along with other examples from ESA and the GEOSS on the use of EO for water management. It facilitates discussion on the role of EO in the SDG water monitoring.
