“For many years in Brazil, we had this idea that only the state government should take care of public safety…” said Maria Eduardo Couto, Technology and Data Coordinator for Civitas @Prefeitura_Rio. “But what we understood at Civitas and City Hall is that, as a city, we have a lot of information about what is happening in the territory.” By bringing together cross-departmental information, Civitas, an advanced security hub, has assisted in over 4,000 cases and partnered with the Secretariat for Women to develop Mulher. Rio, a platform connecting women facing violence to vital services. Watch SVP and Managing Director @RVHaynes and Maria Eduarda Couto discuss how Rio uses data to improve public safety in this interview at Smart Cities Curitiba:

What becomes possible when city teams can better share information and data across departments? On Wednesday, What Works Cities Director of New Cities Stephen Caines, Esq. joins Jenny Durda (@GlendaleAZ), Abbie Jones (@cityofdayton) and Kelly M. Williams, PhD (Oklahoma City) to discuss how cities are connecting systems and data to strengthen city operations and turn visibility into better results for residents. And tomorrow: Randal Rodger, Program Manager, Geospatial Analytics, Technology & Solutions (GATS), (Gold-Certified @ottawacity/@ottawaville) will share how the city’s digital twin brings data from across systems into one 3D view, informing planning and development across city teams. If you’re at CDAO Government this week, come join these conversations!
As cities modernize their technology, building stronger connections across data, systems and departments is essential to making that infrastructure work for residents. That concept is the focus of two conversations we’re bringing to CDAO Government 2026 in Washington, D.C. Next week, What Works Cities Director of New Cities, Stephen Caines, Esq. will moderate a conversation with Abbie Jones (@cityofdayton), Dr. Kelly M. Williams (Oklahoma City) and Jenny Durda (@GlendaleAZ) to explore the governance, technology and organizational practices that help data work across departments. On September 22, Randal Rodger, Program Manager, Geospatial Analytics, Technology & Solutions (@ottawacity/@ottawaville) will share how the city is building a digital twin that connects geospatial, infrastructure, utilities and planning data to strengthen planning and service delivery. Join us at CDAO Government to hear how cities are building more connected infrastructure and putting it to use: cdao-gov.coriniumintelligenc…

We’re excited to welcome Mayor Kate Colin of @CityofSanRafael to our proposed @sxsw panel! San Rafael is using sea-level rise modeling and flood risk analysis to inform long-term planning. Mayor Colin will bring that experience to the conversation alongside Mayor @DeanTrantalis of @FTLCityNews, in our SXSW 2027 session, “Can Cities Predict Climate Disaster Before It Happens?”, moderated by @RVHaynes, SVP and Managing Director of Bloomberg Philanthropies What Works Cities. Together, they’ll explore how cities are using climate data to prepare their communities for what’s ahead. Thank you to everyone who voted during the community voting period! We’re grateful to have your support for this city-led conversation on climate resilience.

During the COVID-19 pandemic, @cuidadmendoza began using data out of necessity, and that experience became the foundation for a lasting commitment to data-driven government, says María Candela Grec, head of the Department of Strategic Planning and Project Management. What started as monitoring public health data has turned into more than 70 dashboards to track and inform public policy decisions across departments, including finance, human resources, public safety and more. Listen to María’s full conversation with WWC SVP and Managing Director @RVHaynes:

Data capacity is the foundation of local climate resilience. Certified cities prove this every day. From deploying predictive AI for wildfire response to using data for storm tracking and flood modeling, these cities are turning static data into actionable governance. We hope to bring these cities' stories and lessons to the stage at @SXSW 2027 with our proposed session: "Can Cities Predict Climate Disaster Before It Happens?" Vote for our panel: participate.sxsw.com/flow/sx…

📹 In 2020, @Muni_Renca discovered that youth who needed mental health support weren’t receiving it. City hall used data to develop and establish a citywide, school-based mental health initiative called Renca Contigo. SVP and Managing Director @RVHaynes sat down with Nataly Vargas, Head of Local Public Policies, to learn how they use data to implement and design the program. “We wanted to address it with a strategy that was more preventive than reactive,” said Vargas. Listen to the rest of their conversation recorded at Smart City Expo Curitiba.
