Title: Satellite-based UNESCO World Water Quality Portal: Monitoring freshwater quality from space using Earth Observation 
 
Presenter: Sarantuyaa Zandaryaa, Programme Specialist, Division of Water Sciences – Intergovernmental Hydrological Programme (IHP), UNESCO
 
Date:   January 9, 2020, 2pm UTC
 
Abstract:  Water quality information is essential for the Sustainable Development Goals (SDGs) implementation and monitoring. However, data on freshwater quality are scarce at the global, regional and national levels, due to the lack of monitoring networks and capacity. In particular, reliable data on water quality is scarce, or non-existent, in remote areas and developing countries. Innovative approaches such as using Earth Observation (EO) and satellite images can enhance global water quality data.
The webinar aims to demonstrate and enhance awareness on the use of EO for inland freshwater quality monitoring, by presenting the application of satellite-based UNESCO World Water Quality in demonstration basins in different regions of the world.
Under the International Initiative on Water Quality of UNESCO’s Intergovernmental Hydrological Programme, UNESCO has developed a pioneering satellite-based UNESCO World Water Quality Portal with the aim to enhance data and knowledge on freshwater water quality at the global level. The UNESCO Portal provides open access information on freshwater quality at scales from global to basin using remote sensing data (i.e, satellite images).
The UNESCO Portal provides data on five key indicators of the state of water quality: turbidity and sedimentation distribution, chlorophyll-a, Harmful Algal Blooms (HAB), organic absorption and surface temperature. These indicators also provide information on the impact of other sectors and land uses such as urban areas, fertilizer use in agriculture, climate change or dam and reservoir management. For example, tracking changes in turbidity (the degree to which light is backscattered by particles in the water) is useful when monitoring sediment plumes from dredging and dumping activities. Chlorophyll-a is a pigment found in phytoplankton cells, while the HAB indicator shows possible areas affected by harmful algae blooms formed by cyanobacteria containing phycocyanin. The UNESCO Portal uses satellite-derived optical data from Landsat and Sentinel-2 satellites, which are open access.
The UNESCO World Water Quality Portal addresses an urgent need to enhance the knowledge base and access to information in order to better understand the impacts of climate- and human-induced change on water security. It will facilitate science-based, informed decision-making for water management and support Member States’ efforts in implementing the SDG 6, as well as several other Goals and Targets that are linked directly to water quality and water pollution.
The UNESCO Portal allows everyone with open access to information on water quality in every part of the world and thus supports information and knowledge for all, leaving no one behind.

Title: Why a new generation of EO sensors for water quality needs a new generation of in situ validation instruments?
 
 
Date: 31 January 2019, 14:00 UTC
 
 
This webinar will be presented by Dr. Marnix Laanen, co-founder and co-owner of Water Insight, an SME dedicated to water quality remote sensing using both image data and close sensing in situ spectrometers based in Wageningen, The Netherlands. He has a PhD. in Earth and Life Sciences from the Vrije Universteit of Amsterdam specialising in the retrieval of Coloured Dissolved Organic Matter from close sensing spectra validated by laboratory in situ sampling. Within Water Insight Marnix is involved in various H2020 projects and in the optical instrument development (both WISP-3 and WISPstation).
                                              *******************************
 
Abstract:  With the launch of the Sentinel 2 and 3 satellites a new generation of EO sensors is commissioned. However, the use of the current in situ validation instruments for these new sensors might not suffice for a number of reasons, especially for water quality retrieval. The atmospheric correction methods for S2 and S3 over surface water are still in development and is troublesome for S2 (as having a band setting primarily for land applications). In this webinar we will explore the requirements for a new generation of in situ optical instruments for S2 and S3 sensor validation.

GEMS/Water: Evolving a Global Long-term Water Quality Data Repository
27 September 2018
This webinar, coauthored by Philipp Saile (Hydrologist, Coordinator), was presented by Dmytro Lisniak (Hydrologist, Data Analyst) of the GEMS/Water Data Centre, operated by the International Centre for Water Resources and Global Change (ICWRGC), German Federal Institute of Hydrology.
 Abstract: The Global Environment Monitoring System for freshwater (GEMS/WATER) was the first programme of its kind to address global issues of water quality through a network of monitoring stations in rivers, lakes, reservoirs and groundwater on a global scale. Technical cooperation with developing countries was the main focus of GEMS/WATER during its first phase. The program has contributed to the establishment and expansion of national water quality monitoring systems in many countries. Current engagements focus on increasing the availability and promoting the shared access to quality assured data that serves as a base for evidence informed decision making, the facilitation of quality assessments to inform policy makers and the support of work on indicators for the Sustainable Development Goals. In order to provide the information and knowledge base for the development and implementation of policies and sustainable management of freshwater ecosystems worldwide, the GEMS/WATER programme is evolving into an open, collaborative water quality data, information and knowledge hub.
