Topic 4A: Life, Death and Disease in the City

Life, Death and Disease in the City
Adina Chua

This week’s reading by Michael Hebbert primarily emphasizes on the relationship between town planning and public health, of which can be demonstrated through two paradigms.

The first paradigm discusses the importance of street ventilation for public health. During the early nineteenth century, the main goal for the sanitary movement was to achieve a fall in mortality rate and increased life expectancy. Contaminated air was amongst the major health concerns of the time, being weighed just as heavily as concerns for water and sewage, which arose soon after. Filthy air accumulated from decomposing carcasses, waste and other organic matter caused fresh air to be a privilege to have. Enclosed buildings and inadequate street designs, cul-de-sac and narrow streets for instance, were the fundamental causes for poor air quality.
           
Cul-de-sacs inhibited the free movement of air and allowed for the accumulation of dirt. Town planners opted for a different approach known as the concept of thoroughfares where streets were wide and intercepted one another. This not only promoted better air quality but also allowed for public interaction through open spaces. However, the success of standardizing an urban area with an open layout caused for much dispute. Those who had properties of their own were unwilling to permit this change and modification; hence they were compelled to practice their rights of ownership, as adjustments to the urban layout were also unfamiliar grounds to the public. This led to a delayed advancement of street infrastructure.

Nonetheless, with evident improvements in public health, people were convinced and gave support to their local government. Epidemiology played a significant role as it helped to better understand the cause of these illnesses through mapping and analyzing. Take for example, the discovery by John Snow that cholera was water borne during the 19th century epidemics in London. The mapping of areas mainly affected by the disease pointed out the root of the problem.

With such an established street design, there wasn’t much thought on how the lack of greenery would affect the public physically and psychologically. There were fewer human-environmental relationships, which made people seem sickly. This unsettling state led to the concept of The Garden City and also the progress towards suburbia. Urban developments began to sprawl into the outer suburbs instead of promoting urban density. Society favors a country-like feel of being surrounded by greenery and minimal noise disturbances, as dense urban living was deemed unhealthy. Thus, cul-de-sacs became a positive characteristic to have in the neighbourhood as it minimizes congestion and noises.

During this time, town planning still focused on preventive medicine and how the environment affected human health in comparison to the science of bacteriology. The Garden City caused for less public interaction as there were lack of social infrastructure and also isolated from the central urban area.

The second paradigm discusses about the neighbourhood unit through the eugenic movement. The Eugenics Society emphasizes on the improvement of the human race by carrying out ‘biological cultivation’. They thought that if the desired genes were selected and made to procreate, it would improve the genetic quality of the human population.

Preventive medicine was of importance during the eugenics movement because even though selective genes were made to procreate, the public still had to be proactive and refrain from illnesses. There was a need for the continuation of these well-endowed traits as well as the delivery of this concept to the public. Preventive medicine would promote a community-based society where people could interact whilst carrying out activities instead of being segregated in their respective suburban areas. Town planners play an important role in ensuring that all these amenities link to one another for easy access.

The clean sweep approach requires the reconstruction of the entire urban area on the basis of the cellular principle. Where an open layout was desired but also the linkage of all amenities. This would increase courtship and birth rates as well as promote better family ties. However, these ideas were implemented momentarily or even non-existent as the National Health Service (NHS) of London was placed under ministerial control instead of community physicians. This was also the case in Melbourne where the Legislative and Local council were in dispute to see who was responsible for the sewerage and water supply. This shows that each form of government wanted a part over the advancement of urban areas and to prove that they have the ability to bring success.

It was unfamiliar at the time for the combination of social infrastructure to be integrated into residential areas. In addition, the NHS was more reliant on doctors than preventive medicine. Thus, NHS took matters into their own hands and without aid from town planners, public health including its environmental surroundings manage to improve, however not completely. Hence, town planners were criticized for all the justifications and changes made which costs significant adjustments for society.

As stated earlier, the relationship between public health and town planning could be observed through two paradigms. However, during the turn of the 19th century, with new ideas and discussions, a third paradigm emerged. The two important concepts were ‘New Urbanism’ and ‘New Public Health’.

‘New Public Health’ came about due to research showing that in modern times, environmental hygiene can result in longer life expectancy in comparison to clinical interference. This falls back to the concept of preventive medicine. The World Health Organization (WHO) disputed against the dependence on clinical practitioners. The public needs to grasp an insight into the relationship between how the natural environment will affect the built environment as well as public health. Despite shifting back towards preventive medicine, the “New Public Health” people did not contemplate on town planning. It was much more on how to educate the public of this new approach.

“New Urbanism” is much like the urban environment we live in today and is greatly influenced by town planning. It intends to encourage a denser urban living with mixed-use of streets. Instead of confined cul-de-sacs as a place of social interaction, thoroughfares and public spaces would take its place. This concept aims at creating a society that merges confidently and adequately through a neighbourhood surrounded with different social infrastructures. Take for instance; a street-based neighbourhood would promote pedestrianism and greater interaction with different individuals. With urban density, the city is able to promote public transportation, which will reduce the use of cars. Hence, another important factor of “New Urbanism” is that it draws upon environmental sustainability.
