EBB & FLOWSCENARIOS FOR UP-CYCLING RECIPROCAL LANDSCAPES IN ÅRDAL NORWAY
PATRYCJA PERKIEWICZ
PART I: INTRODUCTION
Norway is characterized by its spectacular and very often dramatic landscape. The landscape is often rich in resources: minerals, biomaterial, metalsand energy sources. Norway with a population of just over 5 million people has a massive amount of open spaces. The average density is 15.5 inhabitants per square km. Norwegians are settled in various sized settlements scattered all along the country. Some areas are still expanding and there are cities which offer more attractive economies and opportunities. As a counter point, little villages and settlements have become more vulnerable and dependant on industries or a specif-ic trade that fuels the local economy. The narrow focus of these settlements often specialize in specific types of industry. This focus leaves these communities, in times of crisis, in a very fragile situation. Villages therefore experience the effects of the’ shrinking cities’ phenomenon. Shrink-ing cities refer to cities with a declining demography and/or a declining economy due to a range of causes (Tietjen and Laursen 2008). This creates a surplus of built structures which makes the city become more fragmented and fall into ruin. People migrate to bigger sized towns or cities and it is a complex problem. As a counter point and side effect of expanding cities, they require more energy in order to handle growth. As we are in the era of global warming and increasingly unstable climatic patterns it is crucial to look for new solutions, in order to create stability and secure their futures. The need to minimize the amount of greenhouse gases forces are to look for new types of energy.Norway has a huge hydroelectric power potential. Because of this potential, untouched land-scapes as well as the structure of small settlements are in danger of a radical change. New structures and infrastructures are to be introduces around the country. Hydro-power politics often meet criticism from local communities, which do not approve transformation of the Norwegian monumental landscapes and their traditions. In order to envision a future where both of the con-flicted sides comes to an agreement, this diploma project will seek to envision and analyse a series of scenarios in Årdal that predict or reveal the potential impacts of changes in the region. These scenarios will vary in scope and “realism” and will be assessed on the basis of their likeli-ness to happen. Regardless, it is imperative to envision potential futures in order to better prepare for the changes to come.
Research Overview This research explores possible futures in the Årdal region. In the same time, it seeks to envision potential outcomes and scenarios that could take place in the future. These scenarios could include important topics such as: expansion of hydro-power production; expansion of industries; shrinking cities and climate change, etc.
There is not much of the research into future scenarios in the region. My goal is to reveal the potential of the region through the use of scenarios within the municipality of Årdal. In order to better understand the regions untapped potential, as well as give it an idea of possible ventures for further research into topics such as “the prevention of shrinking city syndrome or the implications of an increase in hydro-power and power management.”This approach and research could bring potential benefits to the community of Årdal as well as similar villages located around Norway.
I seek to understand the potential scenarios through two key parts in this research project.The first part will account for the current situation. This part provides grounding and a platform to provide study and the ability to comprehend the issues at hand.The second part will focus on the future. How scenarios come to pass. What is their potential impact on the future and what are its ramifications?
The research will to this end question:
How do small settlements, the landscape and the industry adapt to the future?
How will the direction they take during their transformation phase impact future choices?
I want to explore the relationship between the industry, the settlement and the landscape. I wish to research possible transformation of each of these elements in order to create set of scenarios. The variety of possible futures can reveal potentials and what impacts that arrive from these inevitable changes.
Research objectives:
What is the current potential in the Årdal region?
How can we maximize the potential of the industry; landscape; hydro-power expansion; the ‘shrinking city’
How does the scenario come to pass and what does it mean for the region. E.g.What would happen if the landscape was take over the area currently inhabited by the local communi-ty? What consequences would an expansion of the power grid within the region cause?
In order to answer the primary questions, problem statements has been further subdivided into more detailed inquiries.
• What is the background for the scenarios?• In light of the current scenario what is the most probable future?• Is it possible for the scenario to change?• What sort of changes need to take place in order for scenario to come to pass?• What are the impacts and implications of the scenario?
The methodology will use a theoretical approach to answer the research questions outlined above. The qualitative method allows for a more flexible and iterative approach that is more open adjust and be able to refine the research ideas and concepts as the inquiry proceeds. This approach is used to be able to assess steps along the way, as the discourse is striped layer by layer to the root of the problem.The methods used to answer the questions can then be summarized in two key points.
Framework
The research project has a theoretical basis, and the intended goal is to be able to inform and envision future scenarios.My focus will be limited to the question of how an eventual change to the system can be seen to impact the future of the region.I feel it is important first to map and analyse the current situation in order to contour the relationship that exists between the current discourse and the one of a “possible future”.
This approach chooses to study and identify series of possible scenarios. Scenarios will exploit and assert on their likeness to happen in the future.
As a piece of research, document and its relevance could be seen as the identification of potential scenarios and events that could inform the public of the re-gion’s potentials. In the same time it will offer a synopsis of possible futures. As well as give a reflection and a social view on the identity and future of small Norwegian settlements.The potential findings could benefit society as a whole and could impact local dynamics in the region.
Initial assessment of the region and identification of scenarios
Assessment of relevant information. Sources: site visit, magazines, journals, reports, interviews, books, pre-diploma research. This part will include a site analysis.
The theoretical developments of scenario management
Looking at the current system and future scenarios I would like to investigate how it could inform society. How the proposed scenarios could be used in revealing possible futures for the Årdal region.
In order to envision potential futures a mix media approach will be chosen. Graphical imagery, model making and textual information are used based on the appropriateness of its visual-communication dealing with a specific scenario.As I continue my work, the next step will be to choose a specific scenario and develop it into a full scale design project.

BIBLIOGRAPHY
Norway is the world’s largest hydro-power producer per Capitan is the sixth largest hydro-power producer in the world. Approximately 120 TWh has been produced during the current year and it stands for 99% of all power production in Norway).
Norway as a country is full of natural resources and has a geography which allows for several hydro-power stations to be established. Norwegian hydro-power projects have a reservoir often located high in a mountain area, with melting water from glaciers or rainfall. The melting water travels through tunnels into plants located underground with an outlet connected with a fjord, or into a river system.

In the same time water reservoirs will play an important role in the mitigation of floods and
droughts, as well as the generation of renewable energy. It is estimated that 50% of Europe reser-voir capacity is located in Norway. As hydroelectric power can be much cheaper than electricity generated from fossil fuel or nuclear energy the hunger increases for more grows every day. This added pressure brings new transmission capacity needs. A new grid is required and with it new infrastructure.
There is a great potential to build new hy-dro-power plants across globe. Climate
changes will increase the amount of challenges their economies. It is important to transform global infrastructure in order to minimize the emission of greenhouse gases. To achieve it fossil fuels will have to replace with hydro-power energy produc-tion. With increasing climatic changes and increasing-ly unstable weather patterns the importance of security is paramount. Hydro-power with a large storage capacity will become much more impor-
tant than before. As an energy source hydro-power is one of the cleanest in regards to the emission of green house gasses or other types of climatic disturbances.With a rising significance to the production of energy, hydro-power has the potential to become a stable solution.

Sognefjord is the world’s second longest fjord and Norway’s longest and deepest fjord. Located between Caledonian moun-
tain range it stretches inwards 205km in to the land and with a maximum depth of 1308m at its deepest point.
The fjord origins can be traced back to the melting of the gigan-tic glaciers during ice ages. Sognefjorden is a natural laborato-
ry of origin studies, the variety of rocks and layering, designates the area as a geological interesting location.

It extends into six main arms, reaching towards the Jotunheimen mountain range in central Norway.
The Sognefjord is characterized with dramatic scenery, as well as being a host to small towns and villages along its shore. The fjord has been used for trafficking industrial materials from the
local industrial cities of Høyanger and Årdal. Around 30 000 peo-ple live along the Sognefjord in little villages in the valleys. The Sognefjord is filled with various cruise ships. Each season cruise ships carrying between 1500 and 4000 tourists during the season.

Because of its landscape characteristics Sognefjord became an important source of water based energy
production. Some of the local communities along the fjord take important part in the generation and export of hydroelectric power to major Norwegian cities including Oslo.
The economical situation of the affected municipalities has improved over the last decades due to a large amount of potential sites that could be developed in order to build new hydroelectricity stations and water dams.
Hydroelectric plants are seen by locals as a blessing and curse at the same time. Con-
stantly the growing pressure for finding new renewable energy sources brings lots of new jobs into the local communities, stabilizing their economic situation. The resistance comes from a belief that hydroelectricity production ruins the natural beauty nature of the fjord, by placing heavy structures and installations across the so far untouched monumental landscape. This is further supported by locals whom believe that hydro power is a threat to animal life and ecosystem.

Årdalstangen
Årdal lies at the bottom of Utladalen and Jotunheimen National Park.
Its location is characterised by a very dramatic and powerful landscape. Located in the traditional part of the fjord it is surrounded by tall mountains and waterfalls. Manmade structures are well hidden between monumen-tal and powerful mountains.

The dramatic landscape is very characteristic for the area. Two villages Øvre Årdal and Årdalstangen is separated by Årdal Lake. Most of local water systems have been modified due to hydroelectric
power production.

Local waterfall systems are not on a priority list of the hydroelectric company. Årdal’s hillsides are riddled with
stone and debris due to regular landslides. Masses of stone brought with the melting water and avalanches during the winter and spring season.

Consequences of the Landslide 2004
Landslides and snow avalanches are a rather com-mon occurrence in the slopes around Øvre Årdal
and Årdalstangen. Due to the characteristics of the Årdal’s landscape the area is under constant threat of landslide and avalanche events. The municipality has been recording the events in order to investigate the phenomena. In 1983 a landslides caused great damage to small boats and docks at Årdalstangen. A tsunami wave was triggered by a large rock slide on the south side of the bay. No one was hurt by the resultant tsunami or falling rocks.

Ytre Moa is regarded as one of the biggest discoveries regarding the Viking age 800 - 900AD. The farm proves that this place had been cultivated, although abandoned after a short period of time, it is theorised this could be because of water shortages.
Sogn villages are one of the driest in the country; therefore development of artificial irrigation became an important aspect of the farming industry in the area of Sognefjord.

Årdals Agriculture Roots
In Årdals’ past the community had a variety of industries and was based on farming, fishing, trade and mining.This can be seen as an abundance of potential in the local landscape and acts as a generator of potential.The unexpected closure of the Tyin hydro-power production, results in the
limitation of Årdal Smelter activity.As chaineffect a numbers of jobs have been frozen.With it comes a need for a new energy source.. in otder to keep the status quo.Meanwhile a domino effect a house of cards event force people to look for other jobs and opportunities.However a reinvention of Årdal’s in-dustry is seen as necessary in order to decrease vulnerability and reliance on
a singular industry, this can be done through the use of landscape activation strategies.A Landscape activation strategy empha-sizes that the landscape that become an active part of social change within the area. This includes traditional elements as well as new innovations. This will allow for a new landscape to be more diverse and multifaceted.The affected industrial activity requires
scenarios that will include reparation of the environmental damages and to pro-tect the cultural heritage of Årdalstange and Øvre Årdal.The potential lies in the vulnerability as-pect to use it as a motivator for change. Vulnerability becomes an opportunity to strengthen the settlement through the redesign of landscape based opportunities this done through a set of interventions

Årdals Fragile LandscapeAluminum activities have greatly affected the local habitat.There are many species within the area that are listed as ‘red’ in terms of vulnerability.Additionally hydro-power production has changed the quality of local water-sys-tems. As a result the aquaculture is not as rich as in the other towns located along the shore of SognefjordenAs the tide ebbs and flows, events, scenarios and consequences are examined
Torolmen Lake 1956
The great height differences invoke a high hydro-power development potential. Most rivers are directed to Årdal lake, which has been dammed by a moraine and is regulated by the hydroelectric
activities in the area. Årdal’s energy consumption increases by an average 5% each year. Most of the energy produced in the municipality is consumed by Hydro’s Aluminium plant.

There is a market and a need for more renewable energy in the area.
Too increases the flow of energy larger 300-420kV power lines are needed.
This proposal is very controversial as a lines sup-posed to cross Sognefjorden itself. Local commu-
nities are against the project.

Tyin Power Station was opened in 1918.The main reason was to support local farms.
In 1933 Tyin Power Station was expanded due to the need of supplying Årdal itself.From 1945 Tyin Power station has been providing energy to all local farms in the whole municipality. A new Tyin Power Station project will offer a greater Production of energy.
The new tunnel is 2,5 km in length and is located in-side the mountain. All lakes on the surface in which
creates a system of 8-9 has been used as reservoirs in the production of energy. Norway is one of the biggest Hydro electric power exporters in Europe. The energy produced in Årdal has mostly a regional and national use. However the new proposal including 420kV power line transmitters will provide allow for export towards UK and the Netherlands.

As most of water system within Årdal community is directly connected with hydro power production,the water quality is often being checked in order
to establish levels the effects this has in regards to the tax it has on the land-scape.

A Landscape Shaped by Natural EventsÅrdal is an area heavily influenced by human actions as well as natural forces. Both have resulted in modi-fication of the areas powerful topography.As a result the urban area has been restricted to per-ceived ‘safe zones’. Human interventions in the land-scape cannot prevent the multitude of natural events that can cause devastation. The understanding of the risk factors involved in the area, could contribute to develop a strategy in order to better provide stable living conditions in Årdal as well as well as protect significant characteristics of the landscape.

A landscape Regulated by the Need of PowerÅrdal is located in the end of the Sogn Fjord. A split water system and the close proximity of mountains create fertile grounds for the establishment of Hydro Electric Power plants. Most of rivers and lakes within Årdal’s water system has already been regulated and modified by hydroelectric companies. It was original-ly introduced as an energy source for farming. The greater part of the energy produced in the munic-ipal¬ity is consumed by Hydro’s Aluminium plant. There is a marked and a need for more renewable energy in the area.In order to deliver more power 300-420kV power lines are needed. The proposal is very controversial as power lines are supposed to cross Sognefjorden.

Årdal has a long industry roots. The importance of the industry and the impact it has on the landscape. Has in the past forced new solution to be developed, in 2020 Hydro Aluminium As will introduce carbon Zero production technologies. This will be possible with the use of the energy coming from the local water systems.

The Shrinking City Phenomena and the potential Årdal Tourist RoutesÅrdal is a part of Sogn og Fjordane a county char-acterized by an aging population. As a result the average age of habitants in the area is 43. Instead Årdal has decreasing amount of inhabitants and an increasing population over the age of 60.Its attempts towards keeping the youth in the county has not been successful, heavy industry does not seem provide the possibilities or the “glue” for young people to stay. Årdal has many natural features that are very rare in comparison with the rest of the country. Its closeness to national park and Jotunheimen should generate tourism, however this aspect seems to currently be non-existing.
