The Local Perspective

Water disasters are widespread, and they always involve people: People who share their observations and opinions online. Large flood disasters are usually covered by tens of thousands of observations per hour. A possible overflow of a reservoir can be noted by only a handful of watchful citizens. FloodTags analyses this data - from Twitter, Instagram, Blogs, SMS, Online news media and more - for any water challenge that water and disaster managers face: From floods to droughts, from drinking water to water conflicts, from water-borne diseases to reservoir management. Among our clients: Worldbank, United Nations and the Red Cross. Read more about our work.

Tweets turned into flood maps that could help save lives


BARCELONA (Thomson Reuters Foundation) - Spontaneous tweets about major floods are being turned into a mapping tool that could be used by emergency services and disaster response teams to save lives and provide aid, Dutch researchers said.

When a crisis strikes, people increasingly find out about it from social media, as individuals and groups take to the internet to spread the word.

After the Indonesian capital Jakarta was hit by floods this February, related tweets peaked at almost 900 a minute, with a significant number including information about location and water depth, according to a joint study by two Dutch organizations, Deltares and Floodtags. Read more
