Physiology of a SMART CITY

From Collyra, we would like to talk about a challenge that we will face with motivation in the coming years. The world population is growing exponentially and this will generate different plans of action to adapt the world to us and as far as possible, that neither our planet nor ourselves will lose out.

To get into the subject, let’s evaluate the situation with DATA (it’s what we like best, there is no better validation than DATA).

How is population growth shaping the future?

The percentage of people living in CITIES since 1800:

Population increase between 1800 and 2040.

In just 100 years of humanity, the population has doubled. You can already imagine the great challenges that lie ahead in order to meet the needs of these CITIES.

More interesting facts:

  • Currently, 1.3 million people are moving to the CITIES every week.

  • There are 21 MEGACITIES around the world with more than 10 million inhabitants. Before 1975, there were only 3: New York, Tokyo and Mexico City.

  • The largest CITY is Tokyo with more than 36 million inhabitants. If it were a country, it would be in the top 35 of countries with the largest population.

  • In 2025 the number of MEGACIUDADES is expected to increase to 29, with the incorporation of the Asian cities Shenzhen, Chongqing, Guangzhou, Jakarta and Lahore, two Latin American cities, Bogotá and Lima, and one African city, Kinshasa.

  • Cities with more than 1 million inhabitants have increased by 500 since 1900. (year 1900, 12 cities, year 1950, 83 cities, year 2011, more than 500 cities) China alone will have 221 cities with more than 1 million inhabitants in 2025.

Very striking data if we consider that with our current resources we will be able to meet all our needs. These resources have been supplying the population for years, but will they be enough for this great population growth?

This helps to understand the economic influence that will occur. Today, the 600 largest CITIES in the world generate 60% of the world’s GDP and over the years, 80% of the world’s economic growth will occur within these CITIES.

We also talk, and not less important, about the environmental impact that we will generate by the simple fact of living. These CITIES consume 60%-80% of the annual energy produced in the world. And being 19% of this consumption due to the lighting of these.


With billions of new people living in urban areas, we have to rethink how our cities will be designed and structured.

For all this, we present you the immediate need for more intelligent cities or as they say in our field, “SMART CITIES”. And cities, as we know them, will be revolutionized.

Cities that through technology, are and will be able to make more optimal decisions in aspects as important as political, social, economic and cultural.

When we hear the word “SMART CITIY”, most of us think that it is something very far from our daily life and from our point of view in collyra, we believe that the term “SMART CITY” is broader than just putting “things to the city to measure”.

“SMART CITY” is helping to reduce traffic in a city by monitoring traffic in real time or free parking spaces.

“SMART CITY” is to control and foresee the possible levels of environmental and/or noise pollution of a CITY in order to make more reliable and transparent decisions of the situation.

“SMART CITY” is to prevent industrial accidents and fires by monitoring dangerous agents in the environment.

“SMART CITY” is to control a person’s comfort parameters (temperature, humidity, air quality) in a building so that they feel comfortable in it.

We could be giving thousands of examples of the term “SMART CITY”, but we would come to the same conclusion, this term is not something that is fashionable or that you should know to make yourself “important” in a conversation with friends.

Characteristics of the “city of tomorrow”: a new generation of cities

The “SMART CITY” is being part of the next industrial revolution, as was the steam engine, cars, electricity, computers or the Internet. Something indispensable if we see it today and when its moment seemed unimaginable.

Looking the CITY as a PLATFORM capable of managing ENVIRONMENTAL DATA (pollution levels, water and waste management), SECURITY (health of buildings, bridges and dams or emergency situations), TRANSPORTATION (lighting on roads, real-time traffic, reduction of travel times and refueling), QUALITY OF LIFE (health, accessibility, sport and leisure) and BUILDINGS (energy consumption and user comfort), according to CISCO, will enable major short-term improvements in energy efficiency and services for citizens.

In conclusion, the “SMART CITIES” is creating and will create as many opportunities as challenges for society. And as CITIES integrate this technology, new business models will emerge to make them smarter.

Opportunities that we cannot leave behind.
