What are smart cities?

Did you know that more than 55% of the world’s population lives in urban areas today? That’s around 4.5 billion people who preferred to thrive–or at least attempt to thrive–in the beautiful chaos that defines modern cities. Those figures in and of themselves aren’t an issue; what’s concerning is that, in some cases, this growth comes with a strain on city resources and sustainability and infrastructure challenges that, as urban population numbers keep shooting up, leaders and other stakeholders must address. Thankfully, as a response to these and many other challenges, governments worldwide are embracing technology, and smart cities are becoming the key to unlocking urban progress and sustainability.

Regardless of how many technological implementations an urban setting has, its development as a smart city is inherently anchored on several key pillars that determine how to integrate technology and data to enhance urban living. Here are the main pillars of smart cities.

1. Information Communication Technology (ICT)

Information Communication Technology is an umbrella term that encompasses all the technologies used to handle, manipulate, and transmit information. It is the backbone of smart cities and includes every device and tech used to handle telecommunications, broadcast media, audio-visual processing, and other data transmission systems.

For smart cities, ICT is critical because, for one, it allows for countless data-processing operations and allows stakeholders to leverage big data analytics to make informed decisions, identify trends, and predict future requirements, all of which are essential for innovation and tech-driven processes. Second, ICT is pivotal in enabling IT-based infrastructure systems such as intelligent buildings, waste and traffic management systems, network-based control protocols, and other monitoring functions inherent to smart cities. ICT also supports the development of smart grids, which are essential for optimal energy distribution, energy demand management, and the efficient integration of renewable energy sources.

Lastly, ICT improves all citizens’ quality of life by enabling the integration of different technologies to support innovative, efficient, and sustainable urban environments.

2. Sustainability

Sustainability is a critical aspect of smart cities because it ensures that all urban development initiatives always meet the needs of the citizens of the present without compromising how future generations can meet their own. As you already know, smart cities focus on the well-being of both the environment and its citizens, and sustainability is critical to help stakeholders achieve that. In that sense, keeping sustainability at the forefront helps smart cities prioritize the use and development of energy-efficient technologies and renewable energy sources that help them optimize the overall levels of energy consumption of the city, contributing to resource conservation.

Sustainable smart cities also make sure to implement robust measures to reduce their carbon emissions by promoting the use of public transportation, hybrid vehicles, and clean energy sources and implementing policies to educate citizens about how they can minimize the environmental impact of their urban activities. Moreover, sustainable smart cities leverage technology to create advanced waste management systems that help stakeholders build optimal collection routes, reduce landfill waste, conserve water resources, and encourage responsible consumption.

3. Smart infrastructure

Smart cities need the proper backbone to ensure that all the system’s parts function properly; that backbone is an efficient smart infrastructure. A smart infrastructure is pivotal for smart cities because it provides the foundation for technological innovation by integrating advanced technologies and digital solutions into the physical infrastructure components of the city. Adequate smart infrastructure is critical for governments and companies to be able to harness the power of data and connectivity to promote sustainability, enhance service provision to citizens, address challenges, and create an overall more resilient and livable urban environment.

4. E-governance

Apart from technological implementations and infrastructural innovations, smart cities also need the proper apparatus to oversee how all the elements operate and facilitate the delivery of all the benefits of smart urban living to citizens. This all-seeing eye is often referred to as e-governance. E-governance, or electronic governance, refers to using information and communication technologies to streamline how governments deliver their services to citizens and other stakeholders. In the context of smart cities, e-governance is pivotal to improving the efficiency of governmental operations and facilitating communication between the government and citizens. To accomplish that successfully, e-governance needs digital tools and platforms such as mobile applications, websites, social media, and other electronic means to transform traditional governance structures and processes and make them more accessible and convenient.
