According to projections by the United Nations, around 68% of the global population is expected to reside in cities and urban areas by the year 2050. As a result of this concentration, there will be a steady rise in emissions and energy consumption over time.
To address these environmental challenges, the need for intelligent urban transportation systems, eco-friendly water management facilities, and energy-efficient buildings becomes increasingly crucial.
Smart cities, driven by ICT frameworks such as IoT technology, offer solutions to enhance the quality of life and ensure urban safety. Some North American cities, like Scottsdale, Corona, and San Mateo County, have already demonstrated the potential of technology in managing city infrastructure and services.
For example, The Scottsdale Water Conservation Office has developed a Smart Water Conservation Application, which utilizes automation and technology to enhance water conservation efforts. The application can classify landscaping materials by highlighting areas on a map and calculating water budgets for individual sites. This saves time, money, and water while providing more accurate and timely data for identifying opportunities to reduce water usage. The application leverages AI, ML, and data analytics to automate classification and calculation processes, improving accuracy and response time. With this proactive approach, the office can effectively promote water conservation outreach and build on its decades of innovative water stewardship.
As a result, the city saved 38 million gallons (about 143845580 L) of water in 2022.

The Role of IoT in Smart Cities
IoT integration in smart cities involves interconnected applications, systems, buildings, and devices, creating highly efficient living and working environments. The technology offers numerous benefits for urban areas, including:
Improves Infrastructure Management
The utilization of IoT devices enables monitoring and management of critical city infrastructure such as bridges, roads, and buildings. This proactive approach helps identify maintenance requirements, reduce downtime, and enhance overall safety.
For instance, IoT sensors installed on bridges can detect corrosion or structural damage and promptly alert city officials, allowing for timely repairs before the issue escalates.
Ensures Energy Efficiency
IoT-powered smart city solutions can be used to improve energy efficiency in a city in many ways. For example, IoT sensors can be installed in buildings to monitor energy usage. The data collected from IoT devices can be leveraged to discover possibilities for energy conservation, such as automatically turning off lights in unoccupied rooms or adjusting thermostats based on occupancy levels.
Furthermore, IoT devices can control smart appliances like thermostats, lights, and water heaters, leading to energy and cost savings for residents on their utility bills.
Enhances Public Safety
Through the installation of IoT sensors in public spaces, cities can detect potential criminal activities or suspicious behavior, triggering alerts to be sent to law enforcement officials in case of any anomalies. Furthermore, IoT devices can play a role in monitoring the health of elderly residents and tracking missing persons.
Improves Waste Management
The implementation of IoT sensors in trash cans enables streamlined waste management by monitoring fill levels and optimizing trash collection schedules, thus contributing to waste reduction. Additionally, IoT tracking of garbage trucks leads to more efficient routing, resulting in reduced traffic congestion and emissions.
Increase Transportation Efficiency
Industrial IoT sensors can be installed in traffic lights to collect data on traffic flow. This data can be used to optimize traffic signals and reduce congestion.
IoT devices can also be used to track the location of public vehicles so that passengers can see when the next bus or train is coming. This can help people to plan their travel more efficiently.
Enhances Citizen Engagement
By deploying IoT sensors in parks and public spaces, data on usage patterns can be collected, leading to improved space design and maintenance.
Additionally, IoT devices can offer real-time information on traffic conditions, air quality, and crime rates, empowering residents to make informed decisions and actively participate in their community.
Health and Wellness
IoT sensors installed in homes can monitor the health of elderly residents, enabling early identification of potential health issues and providing necessary care.
Moreover, tracking residents' activity levels and offering feedback on fitness goals promotes healthier lifestyles among residents.
How IoT Works in Smart Cities?
Smart cities rely primarily on the IoT, which comprises interconnected devices like sensors, vehicles, and home appliances capable of exchanging data.
This data is stored in the cloud or servers, and the convergence of IoT devices and data analytics drives the integration of physical and digital elements, leading to enhanced efficiency, economic benefits, and improved citizen experiences in both the public and private sectors.
Edge computing, present in some IoT devices, ensures that only relevant information is communicated through the network, optimizing data transmission. To safeguard the network, firewall security systems are essential for monitoring and controlling data traffic, preventing unauthorized access to the smart city network and data.
Other technologies contributing to smart cities include application programming interfaces (APIs), artificial intelligence (AI), cloud computing, dashboards, machine learning (ML), machine-to-machine (M2M), and mesh networks. The combination of these technologies further enhances the capabilities and functionalities of smart cities.
Smart Cities are the Key to a Sustainable Future
The undeniable link between turning our cities into smart urban hubs and achieving a sustainable future is evident. Although technology is rapidly advancing, concerns about privacy and AI systems with autonomous decision-making capabilities remain valid. Nevertheless, embracing these innovations is crucial for ensuring the sustainability of city living.
As 68% of the world's population will be residing in cities in the next few decades. Embracing smart technologies becomes essential in preventing cities from becoming an unsustainable strain on resources and infrastructure.
