Regeneration - Treatise TPP1

Design Treatise

The exploration of regeneration This treatise intends to inform a creative and intellectual methodology in which to formulate, test and apply design ideas. The condition which has been selected as a topic (regeneration), will initially be investigated through anthropocentric (human) and biocentric (nature) interpretations and then applied to the construct of landscape through an exploration of different exemplars.

By utilising discovered paradigms and the possibilities of their inter-relationships within the theoretical envelope of ‘Landscape Urbanism’, we will apply these to the concept of Regeneration in order to challenge the status quo within the present theory and process. Ultimately, the application and experimentation of these paradigms, aims to provoke some interesting ideas and interpretations for the process of regeneration in future terms.

The site in which the treatise will evolve is to be set in Idanha-a-nova, a small rural village in central Portugal.

“In extended use: renaissance; renewal, specific of the geographical area by the improvement of it’s economic and social conditions.”

[Oxford English Dictionary: 2011]

“The action of coming or bringing into renewed existence, recreation, rebirth and restoration.”

[Oxford English Dictionary: 2011]

“The action or process of regenerating or being regenerated, in particular the formation of new animal or plant tissue.�

[Oxford English Dictionary: 2011]

Initial Hypothesis Our original thoughts...

“Regeneration is a circular process, which can occur within the biocentric and anthropocentric environment.

The way in which regeneration occurs within the biocentric environment can be described as ‘succession’.

In biocentric terms, it is choosing a point in time where nature can be returned to or progressed forward to. In this case, regeneration does not always necessarily mean ‘moving forward’ in a positive sense, but sometimes returned back to a previous state.

Within anthropocentric terms it is the manipulation and adaptation of conditions for anthropocentric gain. This would include the improvement of social, economical and cultural elements of the environment.”

POC: Point of change

This shows our initial thoughts on how regeneration works within the biocentric environment.

We believed that regeneration in biocentric terms can be a progressive or regressive process, the inception of this usually happens when the landscape comes to a POC [point of change] and regeneration can occur. A point of change that would initiate regeneration could be things such as natural disasters and natural selection.

This diagram illustrates our initial interpretation of regeneration in anthropocentric terms.

We first thought that regeneration in anthropocentric terms would usually be a progressive process, which is only carried forward for anthropocentric gain.

Is it circular?

Questioning the our initial hypothesis

After our initial research stage, as a group, we decided upon our own interpretation of what we assumed regeneration could mean. The belief was that regeneration was a circular process which occurred in both biocentric and anthropocentric systems, which resulted in a point of paramount significance.

Regeneration as a word is widely used in our vocabulary and we encounter it multiple times in numerous contexts. For this reason, we found it intellectually challenging to ‘open our minds’ (so to speak) and think about regeneration in a variety of contexts, not simply as a physical entity or the result of a particular process.

We assumed regeneration to be a circular process with a defining point of ‘paramount significance’.

Although after questioning this conception, we began to realise that regeneration was more of a continuous process.

We therefore began to use the word succession, in order to better describe regeneration as a process which develops over time and space.

The diagram on this page attempts to illustrate our first thoughts on the process of regeneration.

The process starts with a decline, reaches a point of change and then becomes regenerated.

Once regeneration has occurred, a point is reached which is deemed as the ‘point of paramount significance’.

Rethinking Initial Hypothesis The process of refining our thoughts

“After coming to the realisation that regeneration is not always a circular process, we were interested in making comparisons between the two conditions in order to find contrasting characteristics in both the Biocentric and Anthropocentric terms.�

[C.Mitchell, S.Savage, A.Hasa: 9.10.12]

This diagram is an attempt to illustrate regeneration as a circular process. Each block of colour on the diagram represents a different site condition such as climate, microclimate, acidity of soils and any other factors which would cause an alteration to the regeneration process.

If the process was circular, each time regeneration occurs the site conditions would need to be exactly the same as the previous regenerative phase. As the site conditions are almost always going to change, the process will always create something new, meaning it is a unique one off process which simply can not be circular.

Diagramatic representation of contious changing external factors

An impartial viewpoint By utilising case studies from a variety of sources we can determine the process of regeneration in an impartial way.

There are two main types of case studies which regeneration falls into, Landscape and NonLandscape.

Using a variety of case studies gives the opportunity to expand our knowledge base and diversify our opinion, ultimately resulting in an neutral position on the word regeneration.

Fluxuation of the regeneration process

State of Flux Regeneration occurs as a range of processes however, these are NOT necessarily circular in form. The process itself is something which is continuous and often sporadic, linked directly to and influenced by the external factors that are present.

Point of paramount significance

Regeneration

Decline

Original concept diagram of the process

POC If drawn, the process would look like more of an oscillating spiral or sporadic line rather than an ongoing circle. The points of regeneration (shown in the diagram) still exist, just in a different place or form.

The above diagram illustrates how regeneration works as a process, but in greater depth and detail. The horizontal lines indicate various changes or factors which occur and have significant impact on the need for regeneration. I.e A new mobile phone is released, the older model becomes obsolete through choice, therefore regeneration must take place.

Each horizontal line also represents a ‘Carrying Capacity’. The carrying capacity is the optimum level or maximum amount of activity the system can withstand without having to eventually regenerate.

Regeneration is illustrated by the purple line which hits varying points of carrying capacity. When the line meets it’s lowest point (point of change), this is where the regeneration process begins.

Once regeneration has occurred and the environment reaches it’s maximum carrying capacity, this pattern continues to form a cycle of ‘boom and bust’ regeneration. This process can be completely natural (biocentric), or completely induced by man (anthropocentric).

The term carrying capacity is commonly known as a biological term, but it can be linked with patterns created by regeneration.

Maximum Carrying Capacity

Point of Change

Point of Change

The cycle that is created is reminiscent of the ‘Boom and Bust’ cycle which appears in Economics. A boom–bust cycle is an episode characterized by a sustained increase in several economic indicators followed by a sharp and rapid contraction.

“The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water and other necessities available in the environment.”

CIRCULAR

In order to illustrate the relationship between the process of regeneration and the term carrying capacity, the circular diagram (above) has been combined with the carrying capacity and points of change, resulting in a diagram which illustrates a pattern of process.

The outcome of combining the two diagrams illustrates that if regeneration was a circular process it would be very predictable and repetitive, following the same process pattern time after time. In reality, the process is much more sporadic, with various levels and patterns of regeneration, meaning the initial hypothesis is disproved.

A continuous process The external factors which are present at the time of regeneration, influence the way in which the systems operate. As the factors can never be the exact same, the outcomes and processes are continuously changing, resulting in a continuous dynamic regeneration process. This is illustrated in the sporadic nature of the diagram below.

Fig 1: The process of regeneration is sporadic yet still fairly continuous in appearance

Downsview Park In 1999, an international competition was held to select an urban park design for a former military base in Toronto. This 320-acre federal park will provide natural and formal garden environments, offering both passive and active recreation while promoting such themes as environmental sustainability, new ecologies, and the rich heritage of the site.

The way in which the designers chose to visualise their ideas for the site was not in traditional format such as plans, elevations and sections. Instead, the graphics focused upon the process of change which would occur over time. This was an attempt to highlight the significance of land management.

In the example below, the diagram illustrates a continuous process of regeneration which is interupted by an event caused by external factors. Events such as natural disasters, human interventions, instant shift in system patterns can all cause this need for emergency regeneration.

Fig 2: The process of regeneration is continuous, but is affected by an instant change in the pattern of the system

New Orleans - Hurricane Katrina An example of a continuous dynamic system could be the city of New Orleans, where a continuous process of regeneration occurs naturally. However, the sudden drop in the graph above indicates the destruction which was caused by hurricane Katrina, leading the system into a state of emergency regeneration. After the initial need for emergency regeneration, the system begins to return to its former continuous dynamic state.

Emerging Regenotypes Defining types of regeneration

By using case studies to explore anthropocentric and biocentric systems , a pattern emerges which highlights two different, yet significant types of regeneration. One type of regeneration is successive and occurs over a period of time, quite often influenced or initiated by anthropocentric activity. The other type of regeneration occurs in an instance and is often triggered by biocentric activity. The events which cause regeneration to occur often tend to be emergencies, changes in trends or anthropocentric desires.

The two terms which seem appropriate for each type are Continuous Dynamic Regeneration and Emergency Regeneration.

Continuous Dynamic Regeneration is the process that occurs when a decision is made to regenerate a particular entity for benefit. The decision can come from anthropocentric or biocentric driving forces. This type of regeneration is usually a longer process which can take time and planning (anthropocentric), but can also evolve and develop (biocentric).

Examples of CDR include: • Advances in technology • Real estate development • Production of Biofuel • Development of an un-managed forest

Emergency Regeneration is the resulting product of a significant event which forces systems to be regenerated. The significant event will interrupt the standard process/ cycle of regeneration and result in a need for emergency measures to be taken.

The initial onset of a need to regenerate usually occurs within an instance, although the actual regeneration process can go on for varied periods of time.

In anthropocentric terms, regeneration could be a much quicker process due to humans needs of interaction and civilisation i.e Manchester Bombing regeneration.

Whereas, in biocentric terms systems can take much longer to regenerate due to having little or no anthropocentric influence i.e The regrowth of Chernobyl.

An interface for regeneration Outcome of our treatise

The outcome of research in this treatise forms an interface (framework) which allows for communication between anthropocentric and biocentric systems. The interaction between the two is determined by external factors which indicate if there is a need for emergency regeneration or continuous dynamic regeneration to take place.

By utilising the two categories (ER and CDR), external factors and carrying capacities we can predict the nature of regeneration.

In Anthropocentric and Anthro-Bio terms, this allows humans to assess and act up on the situation more effectively and efficiently.
