Cities mimic the characteristics of a living organism but the intervention of forces beyond the population of the city will have an affect on how the city evolves and changes. The growing, and circulating population of a city would be the catalyst of its natural evolution. The connection of the city in a greater global context, the intervention of state powers and the effects of the economic influences at varying scales alters, expands, and minimizes the natural evolution a city would have because of its citizens alone.

Cities have the capacity to have a permanence to them that manifests itself in the population. That does not mean that the city can exists without the physical city. Instead this is saying that evolving city is really the evolving populace that inhibits and manifests the physics city. The physical city is still the most tactual presence of the city in that it supplies the common context for the populace to exist in. Just as Stehphen Johson states in “Pattern Match”, “Certain elements of urban life get passed on form generation to generation because they’re associated with a physical structure that has its own durability. (Johnson 105)

The physical city is such a strong force on the populace that it can stand on it’s own to incubate evolution. This evolution in many case is strong enough to create cities that can be self-sufficient. But cities none the less go through the cycles and patterns that Johnson refers too. In some cases cities die out in other cases cities thrive. The catalysts to these changes of pace of self-sufficient cities is going to be outside effects that are greater then the scale of the city. These outside effects disrupt the natural pace of the city. The natural change a city would go through is altered. This alteration is the breading ground for what Michael Hensel , Achim Menges and, Michael Weinstock refer to as “Emergence.”

The same way that the three propose that the intervention of a new high rise-tower in a city will alter the evolution of the city by impacting the individual, social, political and economic influence effect the city the same way the high rise effects the individual. (Hensel 7) The larger scaled force effects the evolution of the smaller scaled entity.

When a nation enter a period of economic turmoil the city is effected. Those that once maintain a certain lifestyle now have their lifestyle threatened. This changes the nature of the populace and the culture surrounding that populace. This push people into different soci-economic classes. Certain group shrink and others expand in a way that is beyond the normal progression. This can be fast and turbulent. It creates the environment for the emergence of methods and systems. “When very large numbers of people are centred in one place,the resource needed to maintain the environmental quality of the public and private spaces increase exponentially” (Hensel 9).

The significance of this evolution is that this is the way the ad-hoc nature of the informal and often destitute portions of a city develop.

Architecture as Science

When thinking about architecture as a science, one can assume this discipline is highly complex and can also be described as an illusive field with a broad sense of existence.  Professors and other students have often asked me, “What is architecture?”  As I begin to answer, they then ask a plethora of questions which imply contradicting characteristics in my logic.  However, these same individuals cannot give an answer themselves.  I see this as a problem within Architecture in today’s society.  So many designers have different definitions for the term Architecture, but then we wonder why our cities do not have a cohesive design, which can function as a whole instead of segregated autonomous pieces of infrastructure.

 

According to Manuel Delanda in Organic life, a new paradigm must be implemented in order to change the way we view cities towards a positive outcome.  But what will that paradigm be?  Could it be the realization that suburbs are unnecessary and an ostensibly dense from of living should become the new norm for our society?  So far we have spoke about informal cities, and how there is a method to the seemingly chaotic madness that occurs on a day-to-day basis.  I see these methods as a contemporary paradigm that could cause a change in our basic assumptions.

 

In the “Emergence in Architecture” reading it says,” Emergence requires the recognition of buildings not as singular and fixed bodies, but as complex energy and material systems that have a life span, and exist as part of the environment of other buildings, and as an iteration of a long series that proceeds by evolutionary development towards an intelligent ecosystem.”  I would like to replace the term “buildings” with the term “cities”.  We should look at cities as complex energy and material systems that have a life span and exist as part of the environment of other cities.  Cities are made up of neighborhoods, and neighborhoods are made up of a diverse group of individuals who occupy them.  Our neighborhoods constantly change, some for the better, and in most cases for the worse.  In the latter scenario, we see neighborhoods, which were once highly coveted areas turn to “ghettos” filled with crime and poverty.  However, if this highly coveted span of a neighborhood was taken into consideration before it came to fruition we could possibly avoid the downfall of certain areas, which inevitably separate our cities today.

The Architect as the Catalyst

The cities of the modern world are developing at different speeds appropriate to their historical and cultural context. In the global South it seems as if the change is occurring within two halves, one being the formal city and the other in the informal sectors. Each “half” develops its own personality as a correspondence to the problems and desires of the individuals that inhabit its boundaries. However, this separation into “halves” is a quality of change in the urban fabric that can be seen in the history of the evolution of many other global cities.
New York City beginning as a port for incoming and outgoing goods in the new world split itself into sections of specific areas of trade. The city was not created from one master plan like Brasilia or St Petersburg but sprung up as different patches reflecting the many trades of its inhabitants. This is group behavior is almost like an instinct made for the purpose of survival but in this case not personal but rather the survival of business. As Johnson suggests, “Like minded businesses cluster together because there are financial incentives to do so.” [1] This instinct to gather then becomes like an ant colony where one individual does not have much power or attention in regards to his trade but as a whole a unique personality is created that brings publicity and in turn interest into what is being sold. Looking at it in the developing city context, a lonely shanty house does not have much power and has to face repugnance by the rest of society. However, as a whole it can become a living organism whose personality can withstand the criticisms of the inhabitants of the formal sector. More importantly, it gives a voice to those who alone cannot create change within their own “half”.
There are specific factors that trigger change within a city. Whether it be political, economic, cultural, or geographic a catalyst needs to exist in order for the change to come about. Like in chemistry where the “special ability of catalysts to intervene in the dynamics of other processes, called enzymes allow the control of more chemical reactions.”[2] In the evolution of city the catalyst is the person who understands the “halves” created within the urban fabric but perhaps feels that she/he does not belong in any of them. Furthermore, it can be that he/she sees the city in a different manner than others and for this reason wants to bring change in how the processes of each “halves” carry themselves. I believe that as architects we can work to serve as catalysts because our profession allows for the creation of order through form and function. We have the opportunity to re arrange things in a way that we see fit and allow for the better connection between the interactions of each disciplinary group within society. In a sense, an architect makes formal the process of entrainment in order to gain power above the rest and actually carry out the change desired. As Johnson describes, “the transition from nonsynchronized to synchronized oscillations can be understood as a bifurcation in which a set of separate limit cycles transforms themselves into a single attractor.” [2]

Change within a city will never stop, it might slow down like the change in cities from roman times to medieval but it continues to fluctuate almost like the law of conservation of energy. The architect can then serve as a mediator between transitions because he/she look at all the “halves” inside a city and decide what’s best. Architects can help create these moments of transition or “bifurcation” within separate areas of society to create unification within the patchwork of the informal and formal city.
