Water scarcity in semi-arid environments of our Earth: challenges and recent developments for risk mitigation

Since 21 years water specialists from governments, admin- istration, NGOs, consulting, industry and science meet every three years to present new developments and to discuss possible solutions for the most important water related challenges. This year, the 8th World Water Forum (“WWF8”) gathered about twenty thousand participants in the capital of Brazil. It took place from 18th to 23rd of March 2018 in Brasilia and was jointly organized by the World Water Council, the Brazilian Federal Government and the National Water Agency of Brazil

Over 200 sessions, panels, events were made accessible to all types of representatives and stakeholders as well as scientists, coming from more than 170 countries.

The Water Science Alliance and national and international partners organized a special session at the evening of the World Water Day, March 22, with a focus on the globe’s water scarce regions and how to deal with it. Session title: “water scarcity in semi-arid regions of our Earth: main challenges and recent development for risk mitigation”.

The session comprised 12 presentations, about half from Germany and the other ones from international speakers and took three hours, was well attended by almost 100 partici- pants and created lively discussions.

After a short introduction by the session chair, Prof. Axel Bronstert from Potsdam University, about the overall challenges and the session outline Dr. Ulrike Pokorski from GIZ gave a keynote talk about how water science and the transformation to application can improve informed decision making. This talk was followed by presentations on recent new developments and research results from different German institutions, e.g. TH Köln (ITT), United Nations University (EHS) at Bonn, University of Stuttgart, the KIT, Campus Alpine in Garmisch as well as the University of Potsdam and international partners, most of the from Brazil.

The presentations focused on various application examples from dry regions of the Earth with a focus on South America, esp. Brazil. The topics ranged from seasonal prediction of water resources, estimation of sediment loads into reservoirs in semi-arid regions, water quality problems, efficient irrigation and water use as well as water supply in water scarce regions.

The next World Water Forum will take place in the Capital of Senegal, Dakar, in March 2021.
