38th EARSeL Symposium in Chania, Greece

The 38th annual EARSeL Symposium and workshop took place between the 9th and 12th of July at the Mediterranean Agronomic Institute of Chania (MAICH), Greece. Participants and experts from all over the world presented interesting works and advances dealing with contemporary topics of interest such as natural and man-made disasters, agriculture and food security, forestry, hyperspectral and thermal remote sensing, urban and 3D remote sensing, etc. Among the keynote speakers were Gilberto Camara (GEO secretariat director), Ursula Gessner from the German Aerospace Center, Pierre Deforuny from UC Louvain, Patrick Hostert from the Humboldt University of Berlin and Matthew Hansen from the University of Maryland. ZFL had a numerous participation with 6 plenary talks and 2 posters on topics involving the use of remote sensing and GIS for characterization of droughts and their impacts on different land covers, wetland mapping, optical and SAR time series analysis and analysis of deforestation drivers in tropical forests.

EvIDENz Workshop in South Africa 2018

The EvIDENz stakeholder workshop on Earth observation-based information products for drought risk on a national basis took place between June 4th and 8th 2018 in the cities of Pretoria and Bisho in South Africa. The event was organised by the Disaster and Emergency Management Training and Education Centre (DiMTEC) of the University of the Free State (UFS) and UN-SPIDER in cooperation with ZFL, UNU-EHS and the National Disaster Management Centre of South Africa (NDMC).

The event included a session of training to present to the users the workflows and methods developed by the EvIDENz group based on remote sensing datasets to evaluate the risk associated with droughts and their socio-economic impact on the livelihoods of people that depend on agriculture and livestock in the province of Eastern Cape. ZFL also presented drought risk maps showing the degree of severity of droughts on crop and grasslands for Eastern Cape. The main focus of these activities was to support the implementation of the SFDRR (Sendai Framework for Disaster Risk Reduction 2015-2030) at a provincial and national level in the monitoring of the impact of droughts in the agricultural sector.

Participants included people from several provincial disaster management centers, the South African Police Service (SAPS), the South African National Space Agency (SANSA), the Agricultural Research Council (ARC), the Department of Cooperative Governance and Traditional Affairs (COGTA), the Department Of Water And Sanitation (DWS), the Council for Scientific and Industrial Research (CSIR), the South African Weather Service (SWS), the North-West University South Africa (NWU), the Gauteng Department of Agriculture and Rural Development (GDARD), and the Department of Rural Development and Land Reform (DRDLR) who actively participated in the discussions on methods.

EvIDENz Workshop in Ukraine 2018

Between May 14th and 16th 2018 a workshop and a training session about the methodologies and application of satellite datasets on the characterization of droughts and their impacts on the agricultural sector was conducted in Kiev. The event was organised by the Space Research Institute of Ukraine (NASU-SSAU) and UN-SPIDER in collaboration with ZFL and UNU-EHS. In this event, ZFL presented the workflows and products related to the exploitation of MODIS and medium-to-high resolution satellites such as Landsat-8 and Sentinel 1/2 to evaluate the hazard component associated with droughts within the SFDRR framework (Sendai Framework for Disaster Risk Reduction 2015-2030) for the oblast of Kiev. Hazard and drought classification maps for some sample areas (districts) were introduced to the stakeholders. Proposed methods were explained during a training session.  Additionally, a web application based on the Google Earth Engine cloud computing platform for obtaining diverse products related to vegetation condition was presented. Participants in the workshop included the Institute of Water Problems and Land reclamation of NAAS; the Ukrainian Hydrometeorological Center (UHMC); the Institute of Agroecology and Environmental Management; the State Service of Ukraine for Geodesy, Cartography and Cadastre; the NCSFCT National Center Of Space Facilities Control And Test, the Ministry of Ecology and Natural Resources of Ukraine, the National Institute for Soil Science and Agro-Chemistry Research, the National University of Life and Environmental Sciences of Ukraine, among others, who contributed with their valuable knowledge and experience to the improvement of the proposed methods.  If you want to learn more about the event visit the website http://www.un-spider.org/news-and-events/events/stakeholder-workshop-earth-observation-based-information-products-drought-0.
