EvIDENz Stakeholder Workshop in Ukraine

The partners of the EvIDENz project conducted the second stakeholder workshop entitled “Earth observation-based information products for drought risk on a national basis”.  The workshop was conducted in Kyiv, Ukraine, on December 6, 2016. Partners involved in the organization of the workshop included the Space Research Institute (NASU-SSAU) of the Ukraine, ZFL, UNU-EHS, and UN-SPIDER. The workshop was attended by 15 key stakeholders of Ukraine involved in disaster risk reduction including the State Emergency Service, the Ukrainian Hydrometeorological Centre, the Institute of Agro-ecology and Environmental Management, the  Ministry of Agrarian Policy and Food of Ukraine, the Institute of Agro-ecology and Natural Management, the National Centre of Management and Testing of Space Facilities, the State Water Resources Agency of Ukraine, the Ministry of Ecology and Natural Resources of Ukraine.EvIDENz stakeholder workshop Ukraine

By bringing together a small and effective group, the workshop promoted the discussion concerning the contribution of the EvIDENz project to drought monitoring, vulnerability and impact assessment as well as to the Sendai framework. Participants agreed to work together to contribute to develop a drought risk assessment procedure as a way to provide drought risk information to improve preparedness and prevention efforts in Ukraine. Furthermore, it was agreed to seek ways to share with other countries the results achieved in this project.

The workshop agenda included presentations, discussions and an overview of the work plan including details of the EvIDENz project, drought risk management, international conventions like the Sendai framework and Earth observation for drought monitoring.

The EvIDENz project targets drought risk, which is a frequent natural disaster in Ukraine. Droughts affect hundreds of people and trigger considerable economical losses every year, especially in the agricultural sector.






Gunter Menz

Wir trauern um unseren Doktorvater, Mentor, "Jefe", Kollegen und Freund

Prof. Dr. Gunter Menz

(+18.11.1956 ✝ 9.8.2016)

On 9th August 2016, Prof. Dr. Gunter Menz passed away after an accident. Gunter Menz studied geography and mathematics in Freiburg, Germany. He received his PhD degree from the University of Freiburg in 1987 and qualified as a professor in Bonn in 1993. He worked as a professor at the Universities of Mainz and Bonn. An often-mentioned and formative period of his scientific career was the time he spent as a visiting scientist at the University of California in Santa Barbara, USA. In 1996, Gunter became a professor for remote sensing at the University of Jena, Germany. Two years later, in 1998, he became a professor at the University of Bonn where he led the Remote Sensing Research Group (RSRG) at the Department of Geography. Together with two colleagues he founded the interdisciplinary Center for Remote Sensing of Land Surfaces (ZFL) in 2001. From 2001 to 2010, Gunter was ZFL’s spokesman.
Africa, in particular East Africa, was always a matter of his heart. He often visited colleagues and friends in the region, raised funds for research projects in Africa, invited African scientists and was an open and committed host to many African students.
Gunter was a passionate geographer with heart and soul, driven by curiosity, taking every opportunity to visit unique and remote places and thus broaden his horizon. He was always able to give helpful advice, providing his students with huge freedom to pursue own scientific interests. His calm and friendly nature shaped the lives and careers of so many graduates. We will miss Gunter’s wisdom, his unconventional ideas, his inspiration.
In mourning we are grateful for the time we could share with Gunter and will remember him as a close and respected teacher, mentor and dear and valued friend.
