SWOS Users’ Workshop

During January 16th and 18th 2018 SWOS organized in Munich a workshop to train users on the methodologies and application of its mapping products. Land managers, ecologists, hydrologists and engineers from several countries in Europe, Africa and Asia actively participated in the discussion with the rest of the SWOS team.

Advanced mapping products such as multi-temporal mapping, water quality, Land Surface Temperature and radar-based metrics were also presented in hands-on sessions along with examples of their practical applications.

EvIDENz Workshop 2017

The project on Earth Observation Based Information Products for Drought Risk Reduction at the National Level (EvIDENz) conducted a workshop from 21 to 22 September at the United Nations Campus in Bonn to present its mid-term results. The event brought together project partners, scientists, policy-makers, practitioners and representatives of governmental institutions.

During the workshop, participants discussed information, knowledge and methods related to drought risk assessment and reduction strategies using the example of case studies in South Africa and Ukraine. More specifically, they focused on:

  • Assessing agricultural drought hazard and to support the Sendai Framework for Disaster Risk Reduction 2015-2030 (Sendai Framework).
  • Quantifying drought risk to support assessment of the Sendai Framework targets “people affected” and “economic loss” and related indicators.

The workshop participants, which included experts from partner organizations in the project's case study countries South Africa and Ukraine, provided important feedback, to support adjusting the workplan for the remaining duration of the project.

EvIDENz is based on the realization that international conventions and frameworks feature more and more goals, targets, priorities for actions and indicators which are quantifiable and measureable rather than being of qualitative nature. This offers new opportunities for Earth observation. The project aims at developing new methods and appropriate means of communicating Earth observation-based information so that it can be used to meet the requirements of convention/frameworks goals, targets and indicators as well as needs by national stakeholders. It concentrates on the value adding chain from sensor data to information to knowledge to informed decision making and implementation. 

The project is carried out by the Centre for Remote Sensing of Land Surfaces (ZFL), University of Bonn, the United Nations University Institute for Environment and Human Security (UNU-EHS) and the United Nations Office for Outer Space Affairs (UNOOSA) through its Platform for for Disaster Management and Emergency Response (UN-SPIDER), together with partner organizations in South Africa and Ukraine.

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.
