The Workshop brought together stakeholders working in frameworks for the monitoring of droughts and of sand and dust storms, including specialists with hydrological and meteorological expertise, as well as representatives of the space industry and of space agencies, representatives of other governmental and non‐governmental organizations and international experts. They discussed and shared user requirements and experiences and presented existing or planned space technologies and applications relevant to the topic at hand.
The Workshop was attended by up to 200 participants with around 30 presentations and 10 posters, with a larger number of national institutions being represented at the plenary sessions on the opening day. There were 18 international participants coming from the following 15 countries: Afghanistan, Austria, Azerbaijan, China, France, Germany, Iraq, Lebanon, Pakistan, Romania, Russian Federation, Sudan, Switzerland, Tunisia and Venezuela (Bolivarian Republic of),
The workshop gathered about 200 specialists from different countries
