The design goal was to reduce computational time and create near real-time flood maps for citizens and emergency managers without compromising on useability or ease of use. CogniCity sends an automated request to users for additional flood information and upon confirmation, displays the crowdsourced information on the web-based flood map,, demonstrating the power of software-as-infrastructure for climate adaptation. UOW researchers developed open source software, known as CogniCity, to detect, in real time, residents’ Twitter conversations about flooding via their location-enabled mobile devices.

As the tenth largest city in the world, and with 80% of the population active Twitter users, there was an opportunity for Twitter to have significant impact on flood management there. Its infrastructure lagged behind its growth rate, making it vulnerable to natural disasters, including severe, city-wide flooding. Jakarta is regularly devastated by flooding during the annual monsoon. was the result of a world-first joint pilot study initiated by researchers at the SMART Infrastructure Facility, University of Wollongong (UOW), in collaboration with the Jakarta Emergency Management Agency (BPBD DKI) and social media giant, Twitter. Peace, justice and strong institutions Read details of the impact in full Industry, innovation and infrastructureġ6.

Related United Nations Sustainable Development Goals:ĩ. This model for emergency response is now seen as best practice by international agencies and has been further adopted by seven cities in four countries.

The tool saved lives by enabling citizens and first responders to avoid and navigate safely through flood zones, and economic benefits were realised through cost savings from manual reporting and reductions in flood-related injury, property damage and disease. This technology reduced the time and cost of situational awareness, empowered citizens to report flood information through social media, and improved human adaptability to environmental disasters. Working with Jakarta’s government disaster management agency and social media company Twitter, UOW researchers developed an open source platform,, to crowdsource and automate flood reporting.
