The Drought-Watch Indices module can calculate five EO-derived drought indices (VCI, TCI, VHI, NDWI, NDDI, and VSWI) and two meteorological indices (SPI and AI) in four temporal scales (day, pentad, dekad and month) by the composition parameters. Both single index and combination index are applied for the drought classification in drought module and the results are demonstrated and saved in different forms.
A break in the heat wave that hit Europe in the summer of 2018 is giving a reprieve to many people who had been suffering from the heat. However, great damages to the vegetation and harvest remain. In Germany, the Association of Farmers has reported damages from the dry spell of over EUR 1 billion. Vegetation growth in various regions and whether there is a long-term trend in vegetation development can be assessed using satellite imagery. Identifying regions that are susceptible to drought are important for drought early warning systems and disaster preparedness. In general, the analysis of satellite imagery is based on the spectral reflectance of the surface of the Earth which differs for different surface types such as soil and vegetation. For detecting...

The "Building Mountain Resilience: Solutions from the Hindu Kush Himalaya" report examines the changing problems facing the Himalayan region of South Asia and highlights the potential for technologies, including space-based applications, to inform communities, practitioners, decision-makers and governments alike, and build more resilient mountain communities.
