Interview with Ioana Popescu, Associate Professor of Hydroinformatics at IHE Delft Institute for Water Education

Please describe how your professional (and/or personal) experience relates to space technologies and their applications to water resources management.

I am an expert in hydroinformatics, mainly involved in research projects and research supervision of MSc and PhD students. My research focusses on physically based models for inland waters (rivers and lakes). One of the major fields where modelling is used in water resources is flooding. In order to have adequate representation of floods, most models require large amounts of data, both for model building and model usage.

Interview with Joshua Ubah, Geospatial Environmental Engineer

Joshua is a Master’s student in Tropical Hydrogeology and Environmental Engineering at Technische Universität of Darmstadt. His interest is focused on hydrogeological processes, groundwater modelling, application of remote sensing and GIS in environmental studies, water management and climate change. He also works as a graduate Intern at AgriWatch BV, a company that applies geospatial solutions for precision Agriculture. As a graduate intern, he applies his interdisciplinary knowledge in developing smart-farming solutions using space-based technologies to farmers in the Twente region of the Netherlands. He deploys satellite imagery, field studies and machine learning algorithms to predict the effect of climate change on arable crops. He also utilizes precipitation data to predict rainfall events to aid farmers in determining planting and harvesting periods. Joshua earned a bachelor’s degree in Geological Sciences, his bachelor’s thesis research aimed at carrying out paleoenvironmental reconstruction using paleocurrent indicators of water flow and direction, and application of ArcGIS to produce maps. Currently, he is working on his master’s thesis with emphasis on the impact of the ancient climate on the paleoenvironment particularly on vegetation, where he tries to research plants response to long-term greenhouse periods and short-term warming events on various timescales throughout Earth's history. His research interests revolve around the application of space technologies in providing solutions and tackling climate change.

Interview with Arjen Haag, Researcher and Consultant in hydrology and water management at Deltares

Arjen Haag is a hydrologist and remote sensing analyst working at the Operational Water Management & Early Warning department of Deltares. We talk to him about the role that earth observation plays in his projects, SERVIR-Mekong, his experiences in the space and water sector and his vision for innovation in the remote sensing community. We ask him about challenges related to flood mapping and forecasting, whether water data should be shared openly and the transfer of knowledge to those needing it the most. He shares his insights on the use of satellite data, algorithms and models, as well as artificial intelligence and machine learning. And finally, why sandcastles were important for all of this.

European Space Agency’s “Water Scarcity” Kick-Start

The challenge

Water is one of the most important substances on Earth and covers 70% of the planet. However, freshwater makes up a very small fraction with 97% being saline and ocean-based. While the amount of freshwater on the planet has remained fairly constant over time, the world’s population has exploded, meaning that freshwater is threatened by significant forces, like overdevelopment, polluted runoff, and global warming. 

Workshop on Water Quality Monitoring & Assessment

The Innovation Workshop on Water Quality Monitoring & Assessment, organized by World Meteorological Organization (WMO), United Nations Environment Programme (UNEP), United Nations Educational, Scientific and Cultural Organization (UNESCO) and World Water Quality Alliance (WWQA), co-organized with and supported by the European Commission’s Joint Research Centre (JRC) and in partnership with the International Atomic Energy Agency (IAEA) and the United Nations Institute for Training and Research (UNITAR), will take place from 27 to 29 September 2023 at the JRC in Petten, Netherlands.

Stakeholder

National Space Science Agency

NSSA seeks to establish a sound infrastructure for the observation of outer space and the earth, make Bahrain a leader in space science and technology, build a culture and methodology of scientific research within the kingdom and encourage technical innovation, among other goals. NSSA is interested in satellites to obtain data, to use them for remote sensing and to conduct advanced space research, so it can be the engine for the state in the use of the latest satellite communication technologies.

NSSA’s main projects are as follows:

Water, Peace and Security Partnership

WPS is a partnership of research and civil society organizations that work together towards identifying water-related risks of human insecurity, fragility and conflict, and towards developing analytical and dialogue tools for preventing and mitigating such conflicts. WPS is a collaboration between the Netherlands Ministry of Foreign Affairs and a consortium of six partners: IHE Delft (lead partner), World Resources Institute (WRI), Deltares, The Hague Centre for Strategic Studies (HCSS), Wetlands International and International Alert.
