Etienne Turpin is a philosopher specialised in complex urban systems, aesthetics and visual culture. He believes that the only meaningful way to approach the problem of “urban flooding in the context of climate change is honest, open science with open source software and open data that can be reviewed by a community of users”.
Etienne Turpin is a philosopher specialised in complex urban systems, aesthetics and visual culture. He believes that the only meaningful way to approach the problem of “urban flooding in the context of climate change is honest, open science with open source software and open data that can be reviewed by a community of users”.
“It is well known that the old engineering approach to flooding just doesn’t work in megacities like Jakarta, and the heroic, consultant-based solutions are basically just ways for European firms to steal more money from the people of Indonesia,” Turpin says. “If we could admit that this old approach is a dramatic failure, we could then move on to ask: what can urban residents do together to reduce the dangers of extreme weather events and increase their enjoyment of the urban environment?”
He and Doctor Tomas Holderness came up with the idea of PetaJakarta.org, which uses the open source software CogniCity to “listen” to Twitter for keywords about flooding during the monsoon season in Jakarta. When words like “banjir” (flood) are heard, an invitation is sent to the original user asking them to specify if there is a flood in their location.
Potential flood reporters give details and spread pictures by sharing tweets with the hashtag #banjir with @petajkt. These are then displayed on a free public map visible at PetaJakarta.org, giving real time flood information and reports.
Jakarta has one of the highest concentrations of Twitter users in the world. Tens of thousands of Jakartans used PetaJakarta.org during major floods in 2014 and 2015.
“In the context of a disaster, people tend to turn to what they know, so if you’re using Twitter to get information in general, in a disaster you’ll use it even more frequently,” says Turpin.
We believe municipal governments and emergency agencies need to re-imagine the role of social media as a way of integrating the concerns and reports of residents in a more comprehensive, coordinated way.
The project is the result of a collaboration between the SMART Infrastructure Facility at the University of Wollongong (where both Turpin and Holderness are research fellows) in Australia, the Jakarta Emergency Management Agency, and Twitter, amongst others.
Dealing with flooding, which threatens cities around the world, requires adaptive thinking. In Turpin’s words, “the future of cities will be open source, or it won’t be much of a future at all”. PetaJakarta.org helps the city’s emergency management agency improve response and reduce costs by aggregating real time information whilst giving residents more influence on the process of disaster management.

Although Earth Overshoot Day falls six days later than in 2025, this does not represent an improvement. The shift is the result of revised estimates of the oceans’ carbon absorption capacity, while humanity’s actual ecological footprint continues to grow.
Gigantic wildfires in France’s Gironde region and near Madrid, Spain, have devastated tens of thousands of hectares of vegetation.
Greece has launched a wildfire management system based on nanosatellites and artificial intelligence. A model that other countries are now looking to replicate.
According to analysts, the emergence of a “super” El Niño could trigger a global food price shock, adding to inflationary pressures already fuelled by the conflict with Iran.
Residents of Kanseche, Malawi, accuse ABF of contributing to the devastating 2022 floods through its subsidiary, Illovo Sugar.
Ecuador’s shrimp exports continue to grow, but the country’s mangrove ecosystems are paying the highest price.
A women’s collective in Nigeria is taking on illegal activities carried out by men within a protected area. Their grassroots conservation model is proving so effective that it is now being adopted by neighbouring villages.
What if the International Criminal Court could prosecute ecocide? The debate remains open, and a new proposal is adding momentum to the discussion.
