EO and Copernicus for Flood & Drought Management in Africa – Virtual Training Workshop – December 16, 2022

Floods and droughts are some of the most frequent natural disasters that can become a major threat to livelihoods, food-security, infrastructure and even life. Remote sensing and earth observation provide valuable tools to monitor ongoing floods and drought, assess the current situation from space and produce products that can support stakeholders and decision makers.


This training is organized by the Center for Remote Sensing of Land Surfaces (ZFL) of the University of Bonn in Germany and aims to provide an overview of Copernicus tools and data in the context of floods and droughts. With the help of the tools and platforms presented during this training, you will be able to make use of earth observation data in the context of floods and droughts without the need of extensive background knowledge. There will be a focus on African examples throughout the training. The training is specifically meant for participants from African countries from government agencies, academia, NGOs or other institutions involved in disaster management or risk reduction.


Training schedule (all times are CET):


        10:00am – 10:30am: Introduction

        10:30am – 12:00pm: Droughts

     Includes introduction to droughts as a disaster

     The Global Drought Observatory (GDO) platform and its sister platforms

     Further datasets and possibilities

        (12:00pm – 1:00pm: Break)

        1:00pm – 3:00pm: Floods

     Includes a thematic introduction

     A showcase of the GloFAS (Global Flood Awareness System) Platform

     Examples on how to work with data in the flood context

ZFL staff supports UN-SPIDER Technical Advisory Mission


From September 12 to 16 2022, ZFL staff members Adrian Strauch and Victor Korir are visiting Abuja, Nigeria to support the conduction of a UN-SPIDER Technical Advisory Mission. This includes the co-organization of a three day interinstitutional workshop on the use of space based information for for flood response and early warning from September 12 to 14. In addition, several institutional visits and a smaller project workshop are planned for September 15 and 16.

With these activities, ZFL supports UN-SPIDER's Bonn office and the Nigerian National Space Research and Development Agency.

Dr. Zbyněk Malenovský appointed as remote sensing professor at GIUB 

ZFL welcomes Zbyněk Malenovský as the new professor for remote sensing at the Department of Geography (GIUB) at the University of Bonn! In this position it is foreseen that he will become a member of ZFL’s Steering Committee soon.
As Chair of the Remote Sensing Research Group (RSRG), he succeeds PD Dr. Olena Dubovyk, who has served as interim professor at the Department of Geography since 2019.
Prof. Malenovský’s academic career led him through research positions in the Czech Republic, the Netherlands, Switzerland, Australia, and the United States. Before his appointment at the University of Bonn, he worked as an Australian Research Council Future Fellow at the University of Tasmania. With his international experience and his remote sensing expertise we are looking forward to future collaborations, new projects and interesting research activities. His research interests promise many intersections with previous research at ZFL, RSRG, and other research groups at GIUB. His main expertise lies in the scientific field of optical remote sensing and laboratory & field spectroscopy using drone, airborne- and spaceborne imagery. His specialty is stress ecology and remote sensing of vegetation under climate change, especially in near-shore terrestrial ecosystems of Antarctica, high mountain alpine meadows, or Australian forests.
