Smarter Cities Need Better Decisions

Technological transformation is profoundly changing the way we live, work and organise our cities. Artificial intelligence, data analytics and digital systems offer new possibilities to improve mobility, manage infrastructure, reduce energy consumption and support urban planning.

However, I believe that there is an issue that is often overlooked in this debate: a city does not become truly smart just because it uses more technology. It becomes smarter when it can make better decisions, use resources efficiently and respond to the concrete needs of people and businesses.

Portugal has been investing in the digitalisation of public services and the modernisation of different municipal infrastructures. But technological transformation should not be limited to the creation of digital platforms or the automation of administrative procedures. Its true potential lies in its ability to integrate information and anticipate needs. A better understanding of mobility flows, the use of buildings, the demand for housing or the capacity of infrastructures can allow for more informed investment decisions. A city that can identify its problems in advance is better able to avoid future costs and seize economic opportunities.

There is also a productivity dimension that deserves greater attention. When licensing processes are lengthy, when different municipal services do not share information or when public investments are planned without an integrated vision, the costs end up being borne by companies and citizens. Technology can contribute to reducing these difficulties, but it does not automatically solve organisational problems. Digitising an overly complex procedure does not necessarily mean simplifying it. Often, the real innovation lies in reviewing processes, improving coordination between entities and creating conditions for decisions to be made more quickly and transparently.

The real estate sector and urban development can particularly benefit from this transformation. The use of more comprehensive information on the territory, buildings and infrastructure can help municipalities, developers and investors to better assess projects and their impacts. Artificial intelligence can support the analysis of different planning scenarios, the energy management of buildings and the identification of maintenance needs. However, these tools should complement technical knowledge and human responsibility, not replace them. The quality of data, the protection of information and the transparency of the criteria used are fundamental conditions to ensure confidence in decisions.

The future of Portuguese cities will increasingly depend on the ability to combine technology, planning and institutional quality. We need municipalities capable of working with up-to-date information, collaborating with companies and research institutions and developing strategies that go beyond political cycles. The success of a smart city should not be measured by the number of digital applications, sensors or platforms installed, but by the reduction of administrative costs, the improvement of services, the efficiency of investments and the quality of life provided. Portugal does not only need more technologically advanced cities. It needs cities that are better organised, more productive and capable of transforming information into economic development.
