Changing Public Space... Our Green Space




GREEN SPACE:
Health and Well-Being

Growing up, the park and savanna was part of my childhood, it was part of many people's lives as far as I could remember. It is where I played, other kids played, rode our bikes, flew kites, played football/cricket, the adults exercised, community gathered and events were held. But as the years have gone by, and development took took the forefront of urban areas, green spaces began to dwindle and replaced with concrete structures.





             

            These pictures show some of the few open green spaces found in Trinidad's urban capital (Queens's Park Savannah, Woodford Square).
            Open space is any public lot of land that is not fully developed and to which the public had access too:
  • Green space: parks, community gardens, and cemeteries.
  • Schoolyards
  •  Playgrounds
  • Public seating areas
  • Public plaza
  • Vacant lots    

                  But green spaces with lawn and trees are quite limited in urban areas. With increasing development and growth of business, industries and residential areas there is the associated loss of green space and fragmentation. Public and private organizations have placed less interest and importance on public space and to them it is seen as unnecessary and can be used for economic gain.

                  In the article titled : The Future of Public Spaces: Beyond Invented Streets and Reinvented Places, author Tridib Banerjee explains that public space is becoming less available and of more concern within the past few years. While many trees and green areas are destroyed to accommodate new infrastructure, concern is now being placed on the lack of green space. The decrease in public space is directly linked to changes with respect to political, economic and technological factors. Though much open green space cannot be found in the heart of urban areas, nearby residential areas as planned and designed with green spaces in mind.
                  There is a general decline in public space as population increases associated with urban growth especially in older cities, Banerjee explains, now these green spaces are mostly found in rich suburbs, which is often not open to the general public, as these areas are gated communities or high rise condominiums and apartments that owners only have access to.

Pollution... Why so much???

     
    
         Pollution in cities is inevitable and has become a major issue due to urban and economic growth and industrialization. These pictures illustrate water, land and air pollution in Post-of-Spain, the urban capital of Trinidad. The vast numbers of people who occupy urban areas contribute to some type of pollution. People are quite dis-concerned with the condition of the environment until it starts to pose noticeable health hazards.
         I took these pictures as it depicts pollution in urban areas and I strongly believe citizens should make a more conscious effect to keep their surrounding sanitary and hygienic. City pollution is cause from the congestion of different type of activities in the urban area example:



  • Increasing number of vehicles - Car exhaust emissions (carbon monoxide), especially from Traffic Congestion motor oil and wear from brake linings and tires deposit pollutants on roadways
  • Runoff drainage from businesses -  Solid and liquid waste accumulate in drains and storm drains and clog these water ways
  • Improper dumping of waste - People illegally get rid of waste dumping in drains and rivers and disregard to the law
  • Building maintenance, renovation, construction - building materials, debris, dust all contribute to pollution
  • Removal of tree - Cutting and clearing of trees for construction can cause flooding and reduces the natural process where trees filter the air
  • Industrial activities - emissions and waste products from companies
  • Residential areas - improper disposal of household waste 



          Rapid urbanization has resulted in increased urban air, land and water pollution in major cities attributed to the points listed above. The lack of law enforcement and fines has also contributed to these levels of pollution as home/business/company owners have no fear for illegally disposing waste matter.
         
          Pollution is a problem throughout the Caribbean and can lead to irreversible damages. The following link expands on the potential threats the Caribbean is and will possibly face: Pollution Threats to the Caribbean

           Thought the Caribbean is face with pollution, other urban cities around the world are faced with much more severe pollution problems. Air pollution via toxic emissions from cars, companies and industries have created a blanket of thick smog over cities which poses as a threat to human health.First published in the International Geosphere-Biosphere Programme Magazine in April 2013, they looked at urban air pollution and its effects caused by large urban agglomerations. M. Melamed, T. Zhu and L.Jalkanen discusses a new global assessment that sheds light on the knows and unknowns of urban air pollution in the article titled
  Urban Air Pollution - a new look at an old problem


The Journal of the Air & Waste Management Association presented an Article: Urban Air Pollution in Latin America and the Caribbean


Abstract
 
         Urban air pollution has become an increasing problem in Latin America and the Caribbean. One reason is the rapid expansion in the size of the urban population. This phenomenon is associated with an increase in the number of vehicles and in energy utilization which, in addition to industrial processes often concentrated in the cities, are the primary sources of air pollution in Latin American cities. The air quality standards established in such countries are frequently exceeded although control programs have been implemented. The urban areas more affected by anthropogenic pollutant emissions are Sao Paulo, Brazil; Santiago, Chile; and Mexico City. In Latin America, the population of cities with high priority air pollution problems include approximately 81 million people or 26.5 percent of the total urban population of Latin America, corresponding to 30 million children (< 15 years), 47 million adults (15-59 years) and 4 million elderly people (^>60 years) who are exposed to air pollutant levels that exceed World Health Organization (WHO) guidelines for adequate health protection.

Traffic Congestion... Long Hours in Traffic Jam

 It is well known that all urban areas produce traffic congestion or “traffic jam” and is experienced by the average working person, business man, school/university students, vendors etc. The number of people entering the urban area is well into the 1000’s. Traffic occurs when a volume of traffic generate demand for space greater that the available road space capacity. This type of urban congestion occurs every day at peak hours of the day, (work/school arrival and departure times) where traffic is at its highest. These pictures show some congestion at major intersections on the highways to enter the urban areas and Central Business District.
Living in Arima, I use private transport (our personal cars) to travel to University of West Indies,Trinidad. I generally experience everyday to enter St.Augustine and Arima, and Port-of-Spain. Many people depend on urban areas for jobs, schooling, medical care, entertainment etc. and visit these city areas every day, more than once. It is expected as the population density increases in urban areas and surrounding areas (suburbs and urban periphery) the traffic congestion situation will increase rapidly.
The intensity of congestion is exacerbated by vehicular accidents, working zones, lack of traffic police presence and enforced laws. Daily traffic is a sign of an urban areas and urban growth and will always be a problem. Traffic scientists and urban economists have done research on traffic congestion and proposed and Economic Theory on Urban Traffic Congestion.

To understand the concept of Urban Traffic Congestion from an economic point of view you should definitely take a read.

While research I came across this report on Managing Urban Traffic Congestion by the EUROPEAN CONFERENCE OF MINISTERS OF TRANSPORT
In January 2004, the Organisation for Economic Co-operation and Development (OECD) and European Conference of Ministers of Transport (ECMT) brought together their transport research capabilities in setting up the Joint Transport Research Centre. This document provides a summary of the key messages and findings of the OECD/ECMT Joint Transport Policy Research Centre report on Managing Urban Traffic Congestion. It puts forward policy-oriented, research-based recommendations for effectively managing traffic congestion and eliminating excessive congestion in large urban areas. It also provides a fundamental overview of the nature, scope and measurement of congestion necessary for any effective congestion management policy.

 Managing Urban Traffic Congestion

Why is there traffic congestion?

  • Population growth – more people, more income, more people purchasing cars
  • Unchecked development, urban economic growth, residential growth and congested streets
  • Accidents, events and incidents
  • Street vending 

Some effects of traffic congestion:

  • Long hours in traffic
  • Waking up earlier than desired to get to school or work
  • Leaving earlier or later to avoid the congestion on the roads
  • Fatigue – mental, physical and psychological
  • Less time spent with family and friends
  • Poor air quality

Field Trip Report

Place Check: 
Port-of-Spain Central Business District

POS is the capital of Trinidad and it represents the CBD where there is a high level of economic activity, the centre of trade and commerce. Commonly referred to as “town” pronounced “tong” by locals the heart of POS is the evergreen Woodford Square. THE CBD is bounded by several well known areas such as Independence Square Brain Lara Promenade, Charlotte Street, Henry Street and Frederick Street. However what captures my attention is the way in which the culture and diversity of our people is seen throughout the CBD. The CBD shows our past history and current development through its architecture of historical buildings and new high rise designed buildings. Our old historical buildings reflect our history and need protecting. Restoration and renovation of such building are currently being done and there need to be constant upkeep of them e.g. Magnificent Seven, Museum, Churches, Red House, and City Hall etc.
For anyone who is familiar with POS, they will know the streets are packed with vendors. The congestion of the streets and walk ways is very unpleasant and frustrating. There is also the issue of illegal parking and polluted drains and streets as it is clogged with garbage. More facilities needs to put into place to accommodate these vendors as it is also dangerous to be selling on the streets as vehicles are always passing up and down. Another issue is that of homelessness of the many people within the CBD. At almost every turn on every street you can see several vagrants on the sidewalks. I would like to see a heavier police presence in the area patrolling the streets to ensure safety and more effort put into maintaining clean and hygienic streets.  The criminal activities are increasing in our CDB which will deter many people and leave a negative stereotype of the city. Security and the aesthetic of our CDB need to be improved and help provided to the homeless to ensure their safety. More parking areas need to be constructed to alleviate the situation of illegal parking and crowded streets. 


“ASSESSING GOOD NEIGHBORHOODS”

Jane Jacobs, : “Urban Goddess” Principles of good neighborhoods include:

·                     Mixed Use-Different functions
“The district must serve more than one primary function; preferably, more than two.” Mixed-use districts that provide housing, offices, shops, and other services, attract a far wider range of people, while spreading out their activities over longer periods of time. Consequently, the streets and sidewalks of mixed-use districts are more active and safer both day and night, while being less congested at peak periods. 

·                     Mixed blocks with different buildings of different ages and conditions
 Part of the physical diversity of a healthy district, she argues, is the retention of old buildings mixed in with the new. Old buildings offer cheap space for new businesses and low-cost housing. They also provide the visual and emotional landmarks that anchor a neighborhood in space and time.

·                     Streets with short blocks and numerous corners
A significant contribution to urban planning is her understanding that streets and sidewalks, as much as parks, are the true public spaces of a city. Street traffic is a necessary part of city life, she concludes, so long as one manages the use of those streets to favour buses, taxis, trucks, and pedestrians over private automobiles. Jacobs’s suggestion that streets should be redesigned to favour pedestrians over cars is a precursor to current techniques of “traffic calming.

·                     A dense concentration of people.
Population density is a positive factor in urban residential neighborhoods, as well as in commercial downtown, but density must be coupled with variety. 

Here’s a link to more information and explanation and analysis of JJ’s Principles

By applying the JJ Principles when comparing POS CBD and the area of Belmont, we can see that Belmont has different land use functions. Belmont is more of a neighborhood with some businesses i.e. a community/housing area where as the CBD is mainly concerned with economic activities.  Both areas as accessible via road ways that is well developed and paved. The streets in the CBD are long, wide and straight and can accommodate one-way traffic and streets are well paved and tend to be parallel and perpendicular in relation to other streets which is common is developed commercial business areas. In Belmont we find many short, narrow, winding roads with many corners and blocks that are once again common to community areas allowing for socialization and communication of community members.
 Building type and structure vary in both areas. Belmont comprises of building which are mostly residential, some of which are old reflecting the colonial times and some new housing designs. In the CBD we have a mix of historical architectural designs and new high rise building designs. Both areas possess buildings with many years of age some in good conditions while other are falling apart, and where restoration is taking place, however appearance of building are quite different as they serve different functions such as shops, markets, offices, etc. In terms of population density and concentration, the CDB generally has as higher concentration of people which varies day to day as more people visit the area for work, school and the goods and services provided, however the concentration of people in Belmont in fairly the same and much less than that of POS CBD.


What makes a successful CBD?
  •  Retains the CBD and the city’s history and reflects the culture and diversity of its people
  •   Well developed easily accessible road ways (well paved, wide)
  • Centre of commerce and trade providing a wide range goods and services
  •  Room for further and future growth and development
  • Properly designed buildings up to safety code standards
  • Built in pedestrian walk ways to ensure safety (pedestrian friendly)
  • ·         Able to accommodate: residential housing, retail, commercial, schooling/universities, entertainment/recreation, governmental functions, medical care, malls/shopping plaza
  • ·         Managed traffic, crime, illegal activities and pollution
  • ·         Generates revenue and a large portion of the GDP for the country
  • ·         Low levels of unemployment and underemployment
  • ·         Low levels of overcrowding and over population (high population concentration/density)
  • ·         Effective management of homelessness

Picture 1 : The Congested Urban Life Generalized

        
The Town of Arima in Trinidad

           

              I took this picture as it captures the general idea of congestion in an urban city. Taken in Arima, a major town in East Trinidad, this is a typical Saturday morning. Congestion can take many forms in the urban and is depicted in this picture. From actual traffic congestion due to increasing numbers of people and cars entering this urban town, to buildings "jam packed" next to each other and pavements cluttered with vendors, pedestrians and customers. At different times of the day and week an urban area can become even more congested. Urban lifestyle is a chaotic one, and most congestion is found at the heart of a city.

              As a geographer studying urban geography there are many models and theories which attempt to explain the processes and characteristics of urbanization. Within the Caribbean countries all have urban cities which grow and develop at different rates for different reasons. Some well known models are from Burgess 1924, Ullman and Harris 1945, Hoyt 1939, Mann 1965 and Sjobeig 1960, which show the patters and processes involved in the expansion of a city/town. Though these models are not fully applicable to the town of Arima an by extension the Caribbean, what these models all have in common is their starting point, the fuel for a city's growth, the Central Business District (CBD)
Like all models mentioned show, the CBD is at the core of a city where there is a concentration of social, economic, political and cultural activities. The picture above shows the congested street of Arima, as this area is well developed and known for its many businesses, shops and economic activities which draw in people. Along the left hand side of the road there are several businesses and franchise (KFC, Pizza Hut, Rattans, a Chinese store, Bakery), on the right hand side there is the Arima Market, where local and foreign goods and produce is sold, and along the pavements are street vendors. An area such as this is often busy and crowded with people, the general 'hussle and bussle' of life. As further growth, development, expansion and population numbers increase there will be an increase in urban congestion.
            Further pictures will be posted with respect to congestion within urban areas from different aspects going in depth and showing its impact on people and the environment.

Just a little background info

Hi all!!!
Welcome to my first ever blog. My name is Anamika Shari Roopnarine and as the title suggest my blog will take a look into the congestion of urban life for a Geography assignment. My aim is to look at congestion from different points of view and show the effects of this on everyday life, the effect is has on people and the environment.

The word Urban relates to cities and towns. Urbanization is the process by which an increasing amount of people take up residency in urban areas (town/cities). Such areas are prone to growth and development which can have both positive and negative impacts.
