A city is a large human settlement.[a] It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production, and communication. Their density facilitates interaction between people, government organisations and businesses, sometimes benefiting different parties in the process, such as improving efficiency of goods and service distribution. Due to the efficiency of transportation and the smaller land consumption, dense cities hold the potential to have a smaller ecological footprint per inhabitant than more sparsely populated areas. Therefore, compact cities are often referred to as a crucial element of fighting climate change. However, this concentration can also have significant negative consequences, such as forming urban heat islands, concentrating pollution, and stressing water supplies and other resources.
Historically, city-dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for global sustainability. Present-day cities usually form the core of larger metropolitan areas and urban areas—creating numerous commuters traveling towards city centres for employment, entertainment, and edification. However, in a world of intensifying globalisation, all cities are to varying degrees also connected globally beyond these regions. This increased influence means that cities also have significant influences on global issues, such as sustainable development, global warming and global health. Because of these major influences on global issues, the international community has prioritized investment in sustainable cities through Sustainable Development Goal 11.
Other important traits of cities besides population include the capital status and relative continued occupation of the city. For example, country capitals such as Abu Dhabi, Amsterdam, Athens, Beijing, Berlin, Brasília, Buenos Aires, Cairo, Canberra, Copenhagen, Helsinki, Lisbon, London, Madrid, Mexico City, Moscow, New Delhi, Ottawa, Paris, Rome, San José, Santiago, Seoul, Tokyo, Taipei, Ulaanbaatar, Warsaw, and Washington, D.C. reflect their nation's identity. Some historic capitals, such as Kyoto, maintain their reflection of cultural identity even without modern capital status. Religious holy sites offer another example of capital status within a religion, Jerusalem, Mecca, Varanasi, Ayodhya, Haridwar and Prayagraj each hold significance. The cities of Faiyum, Damascus, Delhi and Argos are among those laying claim to the longest continual inhabitation. https://en.wikipedia.org/wiki/City
A city is distinguished from other human settlements by its relatively great size, but also by its functions and its special symbolic status, which may be conferred by a central authority. The term can also refer either to the physical streets and buildings of the city or to the collection of people who dwell there, and can be used in a general sense to mean urban rather than rural territory.
National censuses use a variety of definitions - invoking factors such as population, population density, number of dwellings, economic function, and infrastructure - to classify populations as urban. Typical working definitions for small-city populations start at around 100,000 people. Common population definitions for an urban area (city or town) range between 1,500 and 50,000 people, with most U.S. states using a minimum between 1,500 and 5,000 inhabitants. Some jurisdictions set no such minima. In the United Kingdom, city status is awarded by the Crown and then remains permanently. (Historically, the qualifying factor was the presence of a cathedral, resulting in some very small cities such as Wells, with a population 12,000 as of 2018 and St Davids, with a population of 1,841 as of 2011.) According to the "functional definition" a city is not distinguished by size alone, but also by the role it plays within a larger political context. Cities serve as administrative, commercial, religious, and cultural hubs for their larger surrounding areas. An example of a settlement with "city" in their names which may not meet any of the traditional criteria to be named such include Broad Top City, Pennsylvania (population 452).
The presence of a literate elite is sometimes included[by whom?] in the definition. A typical city has professional administrators, regulations, and some form of taxation (food and other necessities or means to trade for them) to support the government workers. (This arrangement contrasts with the more typically horizontal relationships in a tribe or village accomplishing common goals through informal agreements between neighbors, or through leadership of a chief.) The governments may be based on heredity, religion, military power, work systems such as canal-building, food-distribution, land-ownership, agriculture, commerce, manufacturing, finance, or a combination of these. Societies that live in cities are often called civilizations.
Imagining the Future City
By Rider W. Foley, Darren Petrucci, Arnim Wiek
A rich blend of engaging narrative and rigorous analysis can provide decisionmakers with the various perspectives they need when making choices with long-range consequences for cities around the world.
Issues in Science and Technology is a quarterly journal published by the National Academies of Sciences, Engineering, and Medicine and Arizona State University.
The journal is a forum for discussion of public policy related to science and technology. Our concerns encompass a broad range of themes and perspectives related to the ways that societies seek to advance knowledge and innovation to achieve social goals. Our audience is everyone involved or interested in this effort.continue reading on the author's website:https://issues.org/imagining-the-future-city/
How I imagine "controlcity"
It will be difficult to foresee what the city of the future will be like without intuiting this future and this question is something that depends on variable and unpredictable factors the further we move away from the immediate present. That which is further away in time is more blurred and diffuse (and even surreal if you will), since our little capacity for detachment from the everyday (which is not little) prevents us from obtaining the necessary fuel to travel without restrictions, with the most powerful thing that the human being has "our mind and the ability to imagine and believe in something" (even if that something is something wrong).
If we project the city of the future with our current capacity, we will imagine it with what we do in the present and with our known contemporary technology, which leads us to foresee without fear of being wrong where the paths will go, since there is constant and certain news of where the near times will go.
That is why our most reliable point of support would be in what refers to the next 20 years and that at a technological level is our most immediate certainty.
Artificial intelligence, robotics, biotechnology, nano technology, internet of things, manned and unmanned space travel to nearby planets, space mining, etc.
The global village is already an indisputable reality, if we continue on this path there will be no inhabitant (human or machine) on this planet that is not digitally connected with what that means.
On the one hand, a growing contribution of technology in our development as individuals and on the other hand, an inevitable loss of part of our privacy, at least as long as things continue as they are, in the coming years. At the end of the day, everything translates into the formula: security for privacy (medical security, social, citizen, commercial and economic security, security in robot-piloted transportation, etc.). Although this will be partly so, we will not avoid that the fortuitous, the failures and the chains of errors could happen. Nor do we rule out that the new realities will lead us to new circumstances and problems that will have to be faced from the unusual or novel.
"Arcadians colony Controlcity state" is an illustration of a colony on an exoplanet.
Science fiction literature is already a roadmap to follow without fear of getting lost in the sea of foolish licitness. If it is written, it is in the universe of the possible.
So, could today's urban planners and architects foresee the cities of tomorrow in the next 50 years?
Perhaps, but I don't think so either, since any social change, revolution, pandemic, war, climate change, extraterrestrial contact or catastrophic phenomenon will lead us to a completely dystopian and (to my taste) uncivilized world. So in a thousand years?
-It will be interesting to know how it will be, if the human being will be the same as we are today? But could a citizen of Rome in the 1st century imagine what a citizen of today would be like 2020 years later? Maybe yes or maybe no, what is perhaps more certain is that he would have made a mistake with an inhabitant of the Middle Ages.
I believe that cities will have again the strength they had in the time of Athens, Rome and Egypt and that they will be states and their structures will be completely different, completely technological and mobile, longitudinal and ecological, they will defy the gravity of the planet, or perhaps they will be virtual, and their individuals will be autonomous with a much more developed emotional-telepathic and mental balance, societies where suffering is discarded and happiness comes from the balance of the loss of freedom and belonging to the city connected to the central computer that will provide the security of not being alone anymore.
