SDG.11 Sustainable City
According to projections, nearly 70% of the world population will live in urban areas by 2050. While some megacities are already struggling to cope with the current inflow of people, we need to create sustainable cities in order to make these urban areas more liveable and truly sustainable.


What is a sustainable city?

A sustainable city is an urban development using Information and Communication Technology (ICT) and Internet of Things (IoT) to provide useful information to effectively manage resources and assets. This includes data collected from citizens and mechanical devices, that are processed and analyzed to monitor and manage traffic and transport systems, power plants, water supply networks, waste disposal, etc.

Also called eco-city or smart city, the sustainable city aims to improve the quality of urban services or reduce its costs. It stands out for its specificities: smart management, lifestyle, mobility, housing, as well as a smart economy. Their main goal is to reconcile technological innovation with the economic, social and ecological challenges of the city of tomorrow. Their leitmotiv is the quality of life: how to live better together while respecting our environment.

2.Our Focus———

By 2030, provide access to safe, affordable, accessible and sustainable transport systems for all, improving road safety, notably by espanding public transport, with special attention to the needs of those in vulnerable situations, women, children, person with disabilities and older persons
By 2030, reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management

3. Transportation

Clean and efficient transportation of goods, services and people is essential. In the hope of optimizing mobility, many cities are turning to smart technologies to ease traffic congestion and provide users with real-time updates.

4. Security

Safety is a priority for all cities. The accelerated development of sustainable cities should allow municipalities to better monitor their citizens thanks to CCTV cameras with facial recognition. In addition, state-of-the-art CCTV cameras are also …

Challenges of sustainable city
However, these benefits come with a series of risks


Smart cities use sensor technology to gather and analyse information such as rush hour stats, air quality or crime rates. The implementation of these sensors requires a sophisticated and costly infrastructure.


Even though security is part of the benefits, it can also be regarded as a challenge as the use of IoT and sensor technology increases. In fact, the threat of cyber attacks is a critical issue for smart cities. Also, to avoid concerns about data use, smart cities need to involve their citizens. Awareness, education, and transparency on the purpose of data collection are crucial to make the community feel that they are truly taking part in making their city more sustainable.


Inclusive urbanization must be a priority to deal with the increasing vulnerability of poor and slum populations. That is why we need to ensure that no population is excluded from smart city data collection and use.
