Reflection on the Urban Center

            Upon completion of these blogs, my awareness of the urban has been heightened. This blog in particular focused on the negative impacts these urban areas have had on our environment.  However, through the inspection of several of my colleague's blogs it is apparent that the processes are much more dynamic than they seem. Hence, they cannot be simply seen as harmful activity, rather there are various angles that these actions may be understood.

            Several of my post highlighted the over consumption which is occurring in the urban hubs. This consumption is stimulated by the high concentration of commercial areas within the towns and cities we reside. The main point I made was that these activities are exploiting the natural resources of the environment and breaching the carrying capacities, both in the urban spaces and in those areas where these resources are derived. On inspection of my classmates Cherise Ali and Alea Ali blogs, I found alternative views on the commerce that is occurring.

            Alea's blog post "Nature's Green Delight" focuses on some of the advantages commercial zones offer. The main point that stood out to me was these trading centers are an open forum for social communication and culture dissemination. Hence, they allow the gathering of people who share different background to meet in common areas. When at these areas they share, some of the culture with one another. Therefore, it can be stated that commerce unifies the population of the city.

            On the other hand, Cherise's blog post "Fast pace, fast food" explained the adverse effect commerce of fast foods is having on the city. However, the points raise take a look the negatives from a different angle as compare to my posts. She identifies how the urban population's taste for fast foods is degrading their health. Due to time constraints of a busy city life people settle for the unhealthy fast foods sold by the common franchises. Therefore, proving that there is multiple implications to these activities; they are not defined.

            In addition to these two posts, the blog post, "The Final" by Maya Cameron also intrigued me. This post focused on the dynamism of cities, quoting Mumford's in expressing cities as the products of time. She also expressed that the city will change, while its internal working change alongside. It is for this reason that, definitive descriptions should not be used for the urban. We should understand that these human creations are very complex and ever changing. Hence, when analyzing anything in the urban areas we should take a holistic view of all the inner workings.

            Altogether urban centers are comprised of a series of internal processes. As a result, many adverse and positive effects have ensued. Some of the negatives were highlighted in my blog. However, by reading my fellow colleague's entries it can be said that urban areas are vastly complex. It is for this reason that, the issues associated with these districts be closely observed from all angles. Since the city is intertwined and is constantly growing.

Summation of the Urban-enviro problem

View as you enter Tunapuna

            Take a look and what do you see? Cars, buildings, signs, electric lines, paved road and people. Humans created urban zones, which in turn have served several purposes. One main outcome was the centralizing of human life in concentrated zone. However, it was impossible to predict how many processes and systems would have developed out of the growth of these areas. Hence, I believe the uncertainty associated with these zones is one, if not the most important factor which has lead to problems tied to the urban. My entire blog depicted and explained how Trinidad's urban hubs play a role in environmental degradation.


            On examination of this image of Tunapuna, several components, mentioned in this blog, that lead to degradation can be identified. However, it is difficult to escape this reality, as a significant deal of our urban activities is detrimental to the environment in some way. In addition, many of these components are quite useful in other ways. Hence, there is need for urban planning and sustainable methods of development, such that there is minimum harm done to our natural surroundings. Carrying capacity and social capital should also be key terms when defining these new plans.

Selling Degradation

Tunapuna Plaza one of the many commercial outlets located across Trinidad's urban centers.
            No matter which town or city you visit shopping remains one of the most important activity of that area. Commerce in general dictates a large chunk of urban life since it is the means by which people fulfill their wants and needs. Places like the Tunapuna Plaza groups a variety of stores making it convenient for consumers to come and buy. However, there is another side to the harmonious relationship between the urban and its commodities.

            As noted in previous entries overconsumption has lead to several environmental impacts. Commerce provides yet another means by which this trend can continue. The products offered in these stores and retail outlets are largely imported. Raw materials are being harnessed at unsustainable rates to produce the goods available. This brings back the ideas of appropriating the carrying capacity and natural capital mentioned by Rees (1992). Since we are importing our good from areas outside the urban space, we a drawing their resources to fulfill our commercial needs.

            In addition, commercial outlets such as the one depicted are one of the main reasons for the abundant amount of waste produced by urban centers. Solid wastes such as plastics are bought and discarded by the tonnes on a daily basis. As mentioned in a previous post, Trinidad has allocated these materials into landfill sites, which are quickly being filled.

            On a minor note, products, which are readily sold in these places, may not be environmentally friendly. Chemical products and packaging also have their own effects including, ozone depletion and ecosystem degradation.

            So to be brief, commerce in Trinidad has significant importance thus places like the Tunapuna Plaza is prevalent in the urban hubs. However, they have promoted overconsumption in these centers. As a result, of this and other factors the environment has been subject to adverse effects.

The Food for Degradation

Popular fast food outlet found in urban Trinidad.
            There is nothing better than a juicy burger. Or maybe some fried chicken and fries. Or a pizza with extra cheese. No matter the choice, you will find it in a city near you.

             Fast food restaurants like the one shown here is one of the many located all around Trinidad's urban zones. These along with other food places are increasingly popular to the urban population especially. The urban process has influenced what people eat and how much they eat. Since these areas are much more populated, increasing quantities of food are needed to satisfy urban hunger. This has lead to alternative means of producing this food, which, in turn has lead to degradation of the environment.

            It was found that the urban population consumes more meats, fruits and vegetables than the rural population whose primary diet comprises of cereals, tubers and roots. However, since the urban population vastly outnumbers that of the rural, food production is suited mainly to their needs (Regmi and Dyck 2001). Hence, there have been changes in what food is produced in order to meet the demand of the urban population.

For more information on the effect of urbanization on food demand, see:
Effects of Urbanization on Global Food Demand by Anita Regmi and John Dyck.

            As a result, intensive rearing of livestock and commercial agriculture is the chosen method of food production in contemporary society. This however has lead to severe environmental impacts. Large spaces of land are need to rear and cultivate the food needed by these cities; thereby deforestation is prevalent in order to create farmland. In addition, livestock production is one of the major emitters of green house gases. While at the same time, intensive use of fertilizers and build up of animal waste is contaminating the water table through infiltration into the soils (Fao.org 2006).

For more information on the effect of commercial farming on the environment, see: http://www.fao.org/ag/magazine/0612sp1.htm

            Given these points, it has been noted that the urban diet is greatly influencing what is produced as food. Places such as the one depicted have become major food outlets in the cities of Trinidad. This in turn has lead to intensive methods of farming required to satisfy the urban diet which have had severe implications on our environment.

Building Capital

New structure being built in urban Tunapuna
            What is it? Here is a common sight in several of Trinidad's urban areas. New developments within the city core such as malls, theaters, and restaurants all geared to modernizing the inner city and attracting the wealthier class. In urban philosophy, this is known as gentrification. However, we are more focus in how this urban process has disturbed our environment.

            Clearly, from the image a great deal of raw material has gone into building this structure. In addition, much more is still needed to complete it. However, think where all this material comes from. Iron and steel processed from mined iron ore. Cement casting acquired from limestone and other quarried material. Not to mention, the energy required to use the tools. These and several other inputs have been gathered from our natural environment.

            Incidentally, many of these methods of extraction are being done in an unsustainable manner. According to Rees (1992), we are depleting our "natural capital," which are, assets found in our environment that offers support for human functions. Processes such as deforestation, quarrying and drilling are quite apparent, with the intention of fueling economic development in the urban hub, such as the one depicted. If proper measures are not put in place these natural capital will eventually be depleted from our natural systems. Consequentially, this will lead to the disruption of both the environmental and human needs of the future.

            In summation, we always find the need to develop the urban. However, to fuel this need we must deplete our natural assets thereby, degrading our natural surroundings.

Energising Degradation

One of the several gas stations found in Trinidad's urban districts.
            "Fill me up," a quote you would hear several times a day in this spot. This gas station in Tunapuna is one of many located in the urban centers of Trinidad. Its purpose is to provide the fuel needed by hundreds of commuters on a daily basis. Towns and cities have served to increase the use of energy not only by the means depicted here but also by all other aspects of urban life. This has lead to environmental harm due to the way this energy is obtained and how much is used.

            Automobiles, buildings, neon lights advertisements and people all use energy, and one thing is common between all these, they are highly centered in urban zones. The means of the majority of energy production comes from burning fossil fuels. In Trinidad, this is not different, especially since it is a producer of natural gas. This point is particularly important, as energy cost in the country is quite cheap due to subsidies. Hence, wasting of energy is quite prevalent and has thereby lent to increased degradation.

            Overall, the main impact of the overconsumption of energy is the emission of greenhouse gases, which lead to global warming and subsequently climate change. Urban areas have been found to perpetuate this trend due to the number of activities that require energy. Apart from this, automobile use and industrial processes also produces other harm air pollutants when burning fuel for energy. These gases are emitted into the atmosphere leading to urban smog (Dodman 2009).

            Trinidad's inefficient use of energy has been well documented. In an Express article, the country's energy intensity index, which indicates how much energy is used to produce $1 of GDP, was found to be 4.8. Consequentially proving how wasteful Trinidad really is especially when compared to Barbados's index that is five times less at 0.9 (Renwick 2012). Therefore, the effects noted would be very substantial especially in the urban hubs where most of these moneymaking processes occur.

For more on this article see:

            Overall, urban growth has lead to increased energy consumption in the country. Therefore, there is quite an apparent need for service stations such as the one depicted. However, such overuse of energy is adversely affecting the environment.

The City Grows

Landscape cleared on the outskirts of Princes Town for urban sprawl.
            Here lies a vast space of nothingness, cleared, such that in a few years it can be cultivated with urban infrastructure. This is the urban process and this is how it is degrading our environment. Located just on the outskirts of the commercial of Princes Town this area has been cleared to facilitate urban growth. It has become an all too common trend in all of Trinidad. Urbanization's urban sprawl is taking away our natural surroundings.

            Urban areas draw the population into them since they concentrate numerous amounts of useful services and activities within their boundaries. However, with increasing population there is always the need to expand to accommodate such growth. Hence urban sprawl is usually inevitable as seen here in Princes Towns attempt to expand. This sprawl includes the building of new urban infrastructure or suburban development in order to reduce the clutter of the central town or city.
            Be this as it may sprawl is quite harmful to our environment. As seen, large plots of land need to be stripped of their natural vegetation for this growth to proceed. This removes our natural carbon sinks, the plants, allowing carbon dioxide to build in the atmosphere. Hence, it promotes the greenhouse effect and climate change (Chiotti 2004).

            In addition clearing the land also affects our water supply, where runoff of rainfall increase while at the same time infiltration of water into the soil decreases. This reduces the speed at which our underground aquifers are restored. While at the same time, water running of this land erodes materials into our natural waterways, thereby increasing pollution in those systems.

There effects of urban sprawl:



            Apart from this, more urban space only promotes more of the negatives originally related to the city. Therefore, more cars, consumption and pollution are allowed to perpetuate on a greater percentage of our environment (Chiotti 2004).

            In the end, urban sprawl is a necessary output of the urban process. However, it promotes degradation in multiple ways. Therefore, in places like Prices Town and other urban areas in both Trinidad and elsewhere, urban sprawl should be controlled and planned to reduce its environmental impact.

City Folk are Bad


A view along Tunapuna showing the evidence of high population.
            People, without them urban areas would be non-existent. Urban hubs are man's creation which has one main commonality no matter where they were developed, and that is to gather people. Nothing is more evident here than the influence of people. They cluster, either on foot or in cars, in the streets of Tunapuna all with their own agenda. However, this clustering is degrading our environment.

            Urban centers like Tunapuna attract people into and around its central district. They provide numerous human needs including services, jobs and resources in a centered zone. They are also the location key activity such as commerce. Hence, it is no wonder why people readily flock to these places. Consequentially, this trend has caused congestion and several environmental concerns.

            As people gather, more and more resources are needed to maintain the rising population. Hence, the idea of carrying capacity can be highlighted, where an area can only manage a certain amount of individuals given its resources. Population increases in these urban centers drains the resources of the environment. Food, energy and raw materials are extracted readily to sustain the mass of people. The removal of these resources not only occurs in the urban center but in is taken from places outside these areas as well, thus according to Rees (1992) "urban areas appropriate the carrying capacities of distant "elsewheres"." Hence, issues such as habitat destruction, greenhouse gas emissions and depleted landscapes are prevalent due to the increase of urban densities (Verbrugge and Taylor 1980).

            Altogether, the urban population of Trinidad as depicted is causing harm to our environment. However, there is no easy solution, since these zones readily invite people. Therefore, the need for sustainable growth is always a key matter.
