3. Purpose –Part of the initiative of the WB Water Partnership Program (WPP) dedicated to inform the use of remote sensing technology in the water resources decision-making processes when advantageous and/or facing in-situ data constraints. Audience –World Bank staff –Biophysical science and social scientists related to water management Goals: –Review the current use of EO for water related issues –Describe the current state of the art of water related EO –Suggest the likely near-future (10 y) developments –Provide recommendations to the WPP The WB EO of Water Resources Scoping Report Earth Observation Informatics FSP | Dr Arnold Dekker

12. Example : Ambient Water Quality A Proposed indicator: P and N concentrations as a measure of eutrophication. We proposed that this will be hard to measure in over 10’s millions water bodies across their length and width globally. Another indicator of eutrophication can be increased turbidity due to phytoplankton growth and in hypertrophic circumstances algal blooms (other indicators exist too around macrophytes etc.) Turbidity, Secchi Disk Transparency, Vertical Attenuation of Light, Total Suspended Matter, Coloured Dissolved Organic Matter and Chlorophyll and Cyanobacterial pigment concentrations can already be measured from space.==========  logical solution for assessing ambient water quality!

16. Future Data Access and Analysis Architectures Earth Observation Informatics FSP | Dr Arnold Dekker 16 | World is moving to better integration of multiple data sources & models Lack of access to vital EO data, especially in less developed countries, hampers global actions and treaties on climate change, loss of biodiversity, food security, water scarcity, disaster response, etc.. Available EO archives at agencies are getting too big New Paradigm & Opportunities: “Bring users (& tools) to the data” Greater potential to integrate remote sensing, in-situ and modelled data and services for GEO. Potential to have a sustainable approach to data archiving – critical to defensible information on contentious topics. Create new platforms that can make collaboration easier, whether between companies, researchers or agencies
