The Argentinean National Space Activities Commission (CONAE) has been producing information about recent floods based on radar satellite images. In March, the provinces of Santa Fe and Santiago del Estero suffered from intense floods.
Floods, landslides, and droughts are hazards that are triggered by excess or shortage of precipitation. Monitoring precipitation is important to see those hazards coming and to enable decision makers to take measures as early as possible. Precipitation data - together with anciliary data - thus help to prevent that natural hazards turn into disasters.
The detrimental effects caused by river flooding are increasing to the point the number of people affected worldwide could nearly triple in the next 15 years, according to the World Resources Institute (WRI).
The institute's analysis shows that some 20 million people worldwide are exposed to flooding risks. This number is expected to rise to around 50 million by 2030.
The economical costs of flooding are also an alarming factor. In 15 years time, the annual cost to the world economy could reach more than £340bn.
The Indian Space Research Organization (ISRO) analysed satellite images collected from the CartoSat-2 satellite in order to evaluate the damages caused by a landslide in the Indian states of Jammu and Kashmir.
