LITERATURE REVIEW

My dissertation aims to explore the importance of nature to an urbanite living the fast pace yet numbingly routine life in this concrete jungle. There is no one definition to the relationship of man & nature in the urban context of a city and requires a multi-fold exploration to arrive at any conclusion. My exploration begins with a study of the history and evolution of urban landscape vs. natural landscape in cities. Followed by, research on the effectiveness of existing arrangements of the green relief pockets found in the city and their relationship with urbanism in the city. This forms the basis of research for future propositions made by critics and professionals, leading to any comments that can be made on the relevance of improvement and alterations of the urban morphology. Through this layered researched, I aim to better understand the urban morphology in light of integration of natural relief spaces into the urban landscape and its impact on the urbanites and their social behaviours.

• Role of Nature in the Evolution of the Modern Cities

In the modern era of development (19^th to 20^th century), the growth of urbanization [1] and the modern cities has been a very rapid process. Contrary to the past where human dwellings have peacefully coexisted with nature [2] (Refer to Figure 1), recently there has been a change of pattern. The new architectural layout of the human settlements is a network of cold concrete jungles with little concern for the role of nature in the urban landscape.

Modern cities came as an answer to the population growth after the industrial revolution [3]. Cities grew larger; became the back bone of the economy and following the movement of modernism, [4] came the alterations in the lifestyle of urban dwellers. Exponential growth of construction of high – rise buildings, modern homes etc. replaced and destroyed the natural landscape, paving way for more steel and concrete establishments.

This was the age of ‘man over nature’ [5], where urban planners [6] followed the philosophy of generic patterns, with no attention to localized environments and natural landscapes. Nature was a malleable entity, carved, flattened, relocated and artificially recreated to accommodate the requirements of the built created by man. [7]

Therefore, the concept of green relief spaces and the importance of natural landscape is either; simply not considered, or an afterthought, treated as sheer ornamentation to the buildings. Leaving the cities, which house the larger numbers of population [8], with nothing more than hints of green spaces; causing man to lose all connections to his origins, i.e. nature, ‘ […] there were few who believed in the importance of nature in a man’s world, few who would design with nature’ ^[9]

Karachi faired not very different from this general description of modern cities. Furthermore, being the largest revenue producer and biggest of the few metropolitan cities of Pakistan, it entertains a high influx of rural-urban migration. [10] In order to accommodate the rampant expansion in numbers the city is growing beyond bounds (Figure 2) and destroying surrounding natural landscape in the process. [11]

These studies of the context of natural landscape within the urban landscape lead me to research of how this current composition of the urban landscape impacts its user.

• Urbanism; Between the Urbanite and the Urban Landscape

The first text under discussion ‘A Game on the Urban Experience and Limits of Perception’, [12] a paper that uses the word play to ‘ […] interpret the idea of sociability and sensibility’, ^[13] and highlights the ability of architecture to limit human perceptual [14] interaction.

It touches upon various topics under the category of urban spaces of cities, their architecture and their influence on people. The feature corresponding to my particular field of study is the attempt to understand how the architectural composition impacts the everyday life of the urban dweller. The research proposes use of, new mapping techniques of Psychogeography [15] in the squatter settlement of Istanbul (Pinar Mahalle), as they reflect the, ‘ […] Personal routes, discoveries, psychological distances, and expressions […]’ [16]of the player under observation. This brought forth two main areas of focus; the mundane cycle of everyday life experiences and the limited ‘multi-sensory perception in urban experience’ ^[17]

Psychogeography, the collision of psychology and geography [18] is used as the method of reviving the urban experience of everyday life, in a manner that it arouses a sense of playfulness and awareness within the players, i.e. the users of the space. This playful enthusiasm gives way to the, ‘Theory of Drive’ [19] which tests the geographical bounds limiting perception. ^[20] The dimensions of the boundaries of, ‘ […] social attractions and emotional zones of the urban geography’ [21] need to be recognized so they may be extended to accommodate the players.

One dominant theme that stands out in the paper is the need for intervention or adaption of existing urban spaces to create more than just a visual experience, ‘Instead of mere vision, or the five classical senses, architecture involves several realms of sensory experience which interact and fuse into each other.’ ^[22] This ability of architecture needs to be explored and integrated in design at the urban level so within these crowded cities some level of interaction and intimacy may be developed.

However, if these measures are not taken, people will remain stuck in a rut, detached from one another, missing out on common benefits and compromising on a complete multi -sensory perception of spaces.

The second short coming of the urban landscape highlighted by this paper is the cold, stagnant composition of the environment. The design format and layout is mundane, monotonous and lacks any form of relief space, visual or physical. Thus, the dire need of change in the existing format of these cities is made apparent.

Findings of this paper are limiting in terms of contextual relevance, however, couple of arguments discussed above are not far from the truth of Karachi’s cityscape. Furthermore, the methods employed for research can be carried forward as part of primary research techniques [23].

The paper also highlights the role of architectural design and layout of the city as a core participant in the game, defining the lifestyle of the players. Baig [24], supports this argument by saying;

‘It is not people alone who generate the city’s ethos; rather the inanimate objects, such as the urban landscape, also contribute towards forming the urban spirit.’ ^[25]

The, ‘urban mizaaj’ (i.e. urban landscape) is dependent on the opportunities of lifestyles presented to the people by the, ‘inanimate objects’ [26] around them. The largest percentage of inanimate objects of any city is buildings and their connections i.e. architecture, thereby under the theory of Architectural Determinism, [27] built environment becomes the chief dictator of social behavior and interactions. [28]

After understanding the impact of the urban landscape on human lifestyle, the next category attempts to research the relationship of the urbanite and the natural landscape; in order to establish whether some of the gaps of the above discussed relationship can be filled through the addition of natural landscape.

• Relationship of the Urbanite and Nature

As the modern cities continue to progress towards a tech -savvy [29] future the modern man’s isolation from nature continues. Our technophilia [30] and technophobia [31], i.e. the love and fear of technology drives us to desire such a strong command over technology, that it becomes our slave. However, our increasing dependency on the technological advancements has reversed roles, and man has become a slave to technology. Robert Thayer [32], states that our love for technology can be demonstrated by, ‘current residential landscape, dominated by house, driveway and garage’ [33] along the wide roads built to encourage the use and ease of automobiles. We then hide behind a green façade and proceed to live through this dense technological support system. [34]

The result of this isolation is the occurrence of the term ‘solastalgia’; the pain experienced when we withdraw from a natural place we love and cherish [35].Louv, in his books further argues the need for interaction between man & natural landscape and the consequences of lack of this interaction. In his first book, ‘Last Child in the Woods’ [36], he put forward the disadvantages on the development of children due to lack of exposure to, ‘Vitamin N’ (N – Nature) [37], causing a syndrome of ‘Nature Deficit Disorder’ [38]. This is not a medical diagnosis but it is used to create awareness of the detrimental effects of this divide. These theories stemmed many outdoor class room programs and incorporation of interaction with nature for children has now become a more popular idea. [39]

However, the impact of the book had a far more reaching impact than just the restructuring or new experimental techniques of education; it also stimulated the nostalgia of many adults. Adults either reminisced the memories of a different childhood, from that of their children or related to the symptoms of the alienation from nature.

He further supports his argument with simple examples such as, “Depressed people who were prescribed daily outdoor walks improved their moods compared to patients walking in a mall. Alzheimer patients exposed to natural light fluctuations experienced less agitation and wandering.” ^[40]

The deficiency that Louv discusses in his works highlights the importance of ‘Vitamin N’, to enhance our physical and mental health. This concept can now be tied back to the discussion in the previous section of relationship between urbanites and the urban landscape. The flaws in the urban landscape are having a detrimental effect on the city dwellers and can be countered with the integration of the natural landscape in the cityscape.

Testing this argument further, the next section entails a study of the connections lost between man, nature and cities; if there is a need to reconnect and how these connections maybe made?

• Man and Nature within the Urban Landscape

My next text, ‘Design with Nature’, [41] begins with a comparison of the city and the countryside and the stark differences between the two. When exhausted with the over whelming city one retreats to the soothing country side. However, as much as urbanites crave the relief found in the countryside they need the city, whether for compulsion of work or to fulfill the need to be part of the fast pace life, thus, they are drawn back to it. This reflects the divide in the feelings of man, torn between the roads leading to city and countryside, coining the query of the author of this book, ‘It is my investigation into a design with nature: the place of nature in a man’s world […]’ ^[42]

The author writes from personal experience of having grown up in the industrial years of Glasgow and highlights the pros and cons of the city vs. the countryside. From the beginning, the book distinguishes the two poles; nature vs. built, with man caught in the middle. This brings forward a very important field of thought, “ […] if we can create the humane city, rather than the city of bondage to toil, the choice of city or countryside will be between to excellences, each indispensable, each different, both complementary, both life – enhancing, man in nature.” ^[43] This extract highlights the machinelike, cold character of a city discussed in the first part of this research and how an escape to the countryside is merely a bandage solution. Therefore, it proves the need of integration of landscape within the urban context of the city.

Ian L. McHarg [44] categorizes the city and landscape architecture into multiple chapters, giving a detailed design methodology of incorporating nature in urban planning, its application and its need for implementation; by displaying the connections man finds within nature. Within these the more prominent section is of ‘The City; Process and Form’ [45], where the author explores the relationship of the built environment with nature and how when the two are paired together they do not compromise their potential but rather enhance it. He speaks about how the morphology of human settlements should be moulded along the natural morphology. For example, when guidelines for stair treads can be defined, there should be rules against building on flood plains. [46]

‘We are becoming a land of great cities. Villages are stationary or receding; cities are enormously increasing […]’ ^[47]

Similar to McHarg’s thoughts on, ‘city of bondage to toil, the choice of city or countryside’ [48], Ebenezer Howard [49] at the beginning of his book, Garden Cities of To-morrow [50], talks about two magnets, the town and the country but in his analysis he proposed a simple cure, ‘Human society and the beauty of nature are meant to be enjoyed together,the two magnets must be made one’ ^[51]. Thus, resulting in the third magnet the ‘Town – Country’ [52]
