Abstract Exploring how the transition of an active mining landscape into the post-mining era can be anticipated in present, this thesis is attempting the potential dynamics of a productive territory in the particular point of view taken. Domestic energy resources and potential acquire a strategic importance in Greece today while, at the same time, there is a rising awareness for using renewable resources on a global scale, in the premise of overexploitation of the world’s limited resources.1 Looking through the lens of the energy potential of the post-mining landscapes, what are the next landscape and the future of the urbanization in the basin of Megalopolis?

This thesis proposes a series of design strategies to re-configure the productive territory, in a constantly transforming landscape, where new opportunities are emerging for the local populations. Rethinking the productivity of the post-mining landscape introduces an alternative agriculture for the locals, hand in hand with the recovery of the soil and the ecology, and simultaneously creating potential for an energy production scenario based on renewable resources. Under these conditions, biomass is an opportunity for energy production in the local scale and sets new possibilities for the new emerging economies.

Starting from the reading of the current productive landscape and its metamorphoses, this thesis investigates Megalopolis territorial transformation under the overlap of different dynamics through time. Energy, soil and water flows are the essential elements of the current landscape formed by small and large scale processes. These are identified as separate but interconnected systems, where the waste of each system is a potential link to another. “The visibility of flows, processes and systems underlies much of the work to be done, especially when displaying vast movements […] of natural resources that are often operating in remote or underground environments at scales too large for the naked eye”. (Bélanger, 2012, p. 291)

Therefore, the thesis is structured in three main sections. By looking at a framework of 25 by 25 km, the first chapter traces the basin of Megalopolis, giving an overview on the geological features and the urbanization of the basin, as well as the dynamics of the productive territory. Further, the outline of a multilayered landscape is projecting the opportunities for multi-functionality of the site in the closer frame of 10 by 15 km. The second chapter aims to unfold the complex structure of the manipulated topography and the entire machinemade landscape. In order to achieve this goal the thesis used a systemic reading of the landscape alternations and material movement. The previous interpretative analysis leads to the third chapter; the proposed vision for the area until and after the closure, phased in finer grain, which is projecting the spatial reconfigurations in different scales, phasing and seasonality and their impact in the city.

In the case of Megalopolis the radical alternations of the topography, the material movements and the natural water flows come together with the slow rhythm of the provincial city and the countryside. After years of lignite exploitation, the artificial topography, resulting from the mining activity, generates new territorial figures. The “artificiality of landscape created by mining can be seen as an opportunity to create something new during the treatment process”, a potential for new economies for the post-mining city. (Bergbau Folge Landschaft, 2010)

Preface Introduction Towards a post-mining era | a challenge and a threat Framework | systemic thinking and cyclic urbanism

Introduction Megalopolis is a provincial city of approximately 11.000 inhabitants, in the center of Peloponnese, Greece. The area is known as the second Lignite Center of the country and it contributes to the national electricity production with two combustion units currently active. The vast area of 5,000 ha of lignite extraction and combustion facilities are adjacent to the city. The local economy is heavily depending on the mining activity and electricity production. Since the 1970â&#x20AC;&#x2122;s, when the extraction started, the Public Power Corporation2 (PPC) has been a major employer in the area. The internal migration of workers and specialized employees from all over Greece changed the composition of the local population and doubled its size (NTUA, 1992). Simultaneously with the social sphere, the landscape started changing radically as the new production domain started to develop. The mandatory public and private land expropriations either of agricultural land or forest dramatically transformed the rural landscape, generating a complex system of smaller and bigger open pit lignite mines and artificial hills, forming a manipulated topography. The existing self-sufficient settlements were inscribed in the territory, considering a system recovery process. However, the overexploitation of an extraction area in the center of Megalopolisâ&#x20AC;&#x2122; basin is disregarding the recovery of the landscape. The current dominant activity of lignite mining and electricity production is a catalyst of territorial transformations, which at the same time, constitute a disturbance, a rupture in the landscape.

2 The extraction and combustion processes are organized by one corporation that started as public, but is currently being privatized following many other assets in Greece. The short PPC refers from now on to the Public Power Corporation.

Postcard from the future: Megalopolis 2050 _ An imaginary post-mining landscape Megalopolisâ&#x20AC;&#x2122; territory in the post-mining era as a lunar landscape; an image composed by enormous holes on the ground, as craters, along with the left overs of the machinery and the power plant facilities. The impact on the natural landscape is immense and life cannot be sustained as all resources are exhausted. The city itself is a ghost town with few elderly people that refused to abandon their homes.

Towards a post-mining era | a challenge and a threat As other former industrial territories in Europe, Megalopolis, without alternative productive economies is going towards a post-mining era, facing the threat to become a ghost town. Therefore, the emerging scenario of a shrinking economy, through which inhabitants will be forced to migrate inside or outside the borders of the country in order to survive, is evident. After a period of prosperity, decline is coming slowly into the foreground of future Megalopolis. Lignite is indeed a non-renewable energy resource.The reserves are coming to an end. PPC estimates that the lignite reserves in the area will last for about 20-25 years more. The closure of the mines in Megalopolis is projected around 2040. What does the closure mean for the city and the territory? Wouldn’t it be important to start anticipating this transition? Mining in the area of Megalopolis is still today seen a driving force of the urbanization process of the past and the main one of the future as well. Causing both radical landscape and urban transformations, it influenced the cityscape by the immediate doubling of the population and by the spatial expansion of the city in the ‘70’s. The expected rapid decline of this main economy, which supports the local population, around 2040, will influence the city by a direct population decrease. Are there any other supporting economies existing or potential new ones that can sustain this population in the area and how do they form the next step after the industrial city? The post-mining, postindustrial landscapes of coal extraction areas are often considered as if they were in a static condition. Landscape is then a by-product, indirect result of the former activity (Berger, 2006). Exhausted extraction holes as remaining open craters are reminders of a lunar landscape with injured, open wounded ecologies, a ruptured landscape; as indicated for Lusatia, in Germany: “The countryside resembled the surface of the moon” (Bergbau Folge Landschaft, 2010, p.37). This motionless image is directly contradicting to the process of the formation of these landscapes. Would it be possible to think in terms of transitional land use instead? “What futures can be imagined for closing quarries that incorporate design sensitivity beyond erasure and filling, and that embrace their unique endemic character?” (Viganò, 2014, p. 57)

Postcard from the future: Megalopolis 2050 _ An imaginary post-mining landscape Megalopolisâ&#x20AC;&#x2122; productive territory is a composition of different elements and ecologies that form a complex organism in homeostasis. Local energy production from biomass, new agricultural land, bee-keeping and livestock co-exist in a balanced relationship. Recomposed wetlands are hosting migratory species, being at the same time a rich biotope and a biodiversity hub. Archaeological sites are part of this choreography.

The mining landscape is anyhow always dual. “… These landscapes simultaneously carry, on the one hand, the welfare of communities, professional pride, and bright hope for the future | injured bodies, contaminated natural environments, and evaporating social structures.” (Storm, 2015) The perspective in this landscape changes fundamentally when thinking in terms of transitional land uses and programs, when dump is only a phase, a step in a chain of movements, uses, appropriations and developments. The ongoing transformations of an alternating landscape are simultaneously forming the potential ground for a post-mining productivity. Under the vision of a productive territorial park, a balanced coexistence of the different existing and emerging landscapes is challenging the design. The necessary healing of the mining landscape, its environmental recovery goes in parallel with the energy efficiency in a local level and the establishment of new economies related to the productive landscape. “The site acts as a mnemonic device for the making of the new” (Mostafavi, 2010) that creates the conditions for the next development cycle of the city. Already starting from the operational phase of the mines, reclaiming the landscape means at the same time the purification of polluted water and the remediation of contaminated soil, reconsidering the appropriation of the landscape while introducing new economies that will replace the preceding. “Designation of territories, zones of intervention, and modes of organization become soft design processes that eventually lead to the formation of new spatial morphologies and performative ecologies.” (Bélanger, 2012) The socioeconomic crisis and austerity in Greece, is introducing rivers of migration. Tendencies of returning

back to the land immerge. In search of more affordable solutions, young people evaluate life outside the borders of the capital. Taking distance from the uncontrolled speed and the alienation of a big city, the character and the qualities of a provincial city present an alternative scenario. The social inclusiveness and reciprocal relations in combination to the slow rhythms of a resilient and self-sustained living, contribute to a different quality of life. The proximity to nature and short distance between living and working places makes everything accessible in walking distances. Coming back to the land means most of the times a change to an occupation that at least is partially related to the earth and its productivity. Therefore, the future of the provincial city as an incubator, a place of opportunity for new initiatives and new populations acquires different dimensions and the transition to the post-mining era can be “…an opportunity to pay attention to the economic and social aspects of a landscape as well. […] The idea of healing the wounds inflicted on the mining regions quickly and rendering them unrecognizable has given way to the conviction that the best possible use should be made of the opportunity to design a post-mining landscape with great potential for the future development.” (Bergbau Folge Landschaft, 2010, p.40-41) As the productivity of the territory has been defining the development of the area over time, the reconfiguration of the productive landscapes of Megalopolis provides a canvas which forms the synergies and relations to the next phase of development. It is exploring the potential of a landscape in motion as a carrier of the next economies in a coherent composition. The proposed synergies and the biophysical dynamics (Bélanger, 2012) create a multilayered territory in a transitional regime to productivity after mining, cyclic in time and in space.

Framework | systemic thinking and cyclic urbanism This thesis is based on systemic thinking and cyclic urbanism. Throughout simultaneous fieldwork observations, mapping operations and site specific and national data analysis, we examine the different systems of energy, water and soil and their spatial expression. These systems are explained trough generic diagrams and located sections. In each system, the produced waste from the different processes creates a potential linkage to another one, or even a potential to generate another system. The modification of these systems in a series of processes is starting from the current condition and gradually evolving in phases not only until but also after the closure of the mines in a dynamic choreography. The overlap among these different elements interweaves the complexity of the site, as several systems work in the same space. “Both the tree and the semilattice are ways of thinking about how a large collection of many small systems goes to make up a large and complex system. … The semilattice, by comparison, is the structure of a complex fabric; it is the structure of living things, of great paintings and symphonies.” (Alexander, 1965) Finding these potential linkages between the different systems and closing cycles of production and waste is among the challenges of the design investigation, as

they can provide various space qualities in an operative territory. In this study, the section is used as a tool to show the collaborations among the systems; a couple of interconnected operational sections in different positions are being reformed until the closure and after mining. Alan Berger (Berger et al., 2009, p.14) states the importance of an understanding on “…how natural and artificial systems dynamically function in regional territories and small locales, and ultimately feed back into both scales from new design and planning interventions”. Thinking in different scales where the “…larger scale logic is embedded in the smaller scale proposals.” (Berger et al., 2009, p.15) is embedded in the design. The difficulty of capturing the evolution of a moving landscape is also apparent in the design of its transition towards the post-mining era. “The promise of landscape urbanism is the development of space time ecology that treats all forces and agents working in the urban field and constitutes networks of inter-relationship.” (Corner, 2006) The process of modifying the systems has a spatial footprint where productive, cultural, ecological, and urban elements coexist in homeostasis. This project is not about returning the landscape in a previous stage, but reclaiming the diverse productivities of a manipulated territory.

c. Dynamics of a productive territory

A multi-layered landscape

This chapter frames the basin of Megalopolis as a unity, looking first into the geological processes, which explain the existence of lignite in the area, projecting at the same time a continuous but diverse inhabitation. In parallel, the evolution of the urbanization reveals the changing relation between the city and the villages, and further between the city and the productive territory. The transformation of this productivity also reflects different social aspects and urban conditions. How is this multilayered landscape expressed in space and appropriated through time?

a. Geological processes

Considering land as the result of a very lengthy and very slow stratification (Corboz, 1983), it’s important to identify the traces of lost territorial processes. Moreover,, the geological processes and the composition of the geological substratum are defining contemporary conditions. The area of the basin of Megalopolis was a lake in prehistoric times, more luckily composed by three separate water bodies3, with aquatic plants and surrounding dense forests. The inhabitants of the area during the period of Pleistocene were various mammals and other animals. After a tectonic movement that resulted in the subsidence of the basin, water escaped and the lake was gradually becoming a swamp. (Drakonias et al., 2015) Huge volumes of organic matter were buried in layers and fossilized in the bottom of the swamp (PPC, 2015). This evolution is justifying the creation and existence of lignite in seams, in a depth of 250m (Koukouvelas et al., 2014). “Since 1969, the lignite seams have been exploited via open-cast mines and numerous paleontological localities have been exposed during mining operations.” (Panagopoulou et al., 2015) The excavation of lignite is becoming in such way a process of digging into the history of the area’s evolution. 3 The three main lignite deposits have different physicochemical characteristics, probably because of the existence of three lakes. These deposits are: Choremi-Marathousa (total depth 140 m), Thoknia-Kyparissia (total depth of 20-100 m) and Karytaina (total depth of 45 m). The thickness of the lignite beds varies from a few to 5 m. (Kordas, 2006)

The diverse geological formations of the basin reveal their age and the different formation processes. The oldest geological formations which surround the basin are the limestone of the zone of Pindos and the flysch of the Tripoleos (Van Vugt et al., 2000) which construct the basis of the basin (PPC, 2015); while Pliocene (especially in the eastern part) and Pleistocene sediments cover the basin. The eastern boundary of the basin is a series of NW active faults.

The stratigraphic column relates the ground formations with the formation and depth of lignite, as shown on the scheme. The layers of lignite are divided by clay, silt and sand partings of 5-30 m thick (Van Vugt et al., 2000). Because of the shallow depth of the lignite beds, already from the antiquity, there were cases of spontaneous combustion that indicated the existence of lignite.

b. Urbanization in the basin of Megalopolis

The basin of Megalopolis is situated in a strategic location, in the heart of Peloponnese, in Arcadia. Currently, there is good connectivity to Athens and proximity to the bigger cities of NE and SW Peloponnese, Tripolis, Kalamata and Sparta. The geographical strategic location was the reason of existence of the ancient city of Megalopolis, ruins of which lie on the northwest of the contemporary city. Ancient Megalopolis, originally named Megali Polis (meaning in Greek great city) was founded after the defeat of Sparta in 371 BC by Thebes (University of Patras, 2016). The Theban leader Epaminondas encouraged the creation of the new city for strategic purposes, as a fortress towards Sparta, aiming to control its force. Part of this colonization of a new ground was to force populations from 40 surrounding settlements to inhabit the new city. (University of Patras, 2016) Today, ruins from this period still stand. The ancient theater was amongst the biggest of its time, with a capacity of 20.000 people, neighboring with another structure in front, Thersilion. They were both used from the Arcadian people for their assemblies. The agora is located across the river Helisson that was crossing the ancient city. After a long history of alliances and battles, destructions and reconstructions, the ancient city faced decline and abandonment. It was only during the Ottoman Empire, when the village of Sinano started developing nearby ancient Megalopolis, where the contemporary city is. Nevertheless, the settlements in the basin had different relations over time. From period to period, one was more powerful and more important than another, under an interesting story of glory and decline. â&#x20AC;&#x153;It is generally admitted â&#x20AC;Ś that Leondari is not Megalopolis. Where then is Megalopolis? Perhaps at the village of Sinano. To satisfy myself on this subject, I should have been obliged to go out of my way and to undertake researches foreign to the object of my journey.â&#x20AC;? (Chateaubriand, 1814)

Pausaniasâ&#x20AC;&#x2122; routes in Arcadia, source: ATLAS of Morea, A project of the French scientific mission (Expedition Scientifique de Moree) 1829-1838, Athens 2011

Pausanias4, who visited the area (around 143-176 AD), states: Megalopolis was founded by the Arcadians with the utmost enthusiasm amidst the highest hopes of the Greeks, but it has lost all its beauty and its old prosperity, being today for the most part in ruins. I am not in the least surprised, as I know that heaven is always willing something new, and likewise that all things, strong or weak, increasing or decreasing, are being changed by Fortune, who drives them with imperious necessity according to her whim. (Paus. 8.33.1) 4 Pausanias (flourished AD 143-176) was a Greek traveller and geographer who left a valuable work from his trips. Periegesis Hellados (Description of Greece) is a 10 volume guide to the ancient ruins. (Encyclopedia Britannica, 2016) 30

Arcadia was once isolated in the hinterlands of Peloponnese, without access to the sea, mainly occupied by mountains. Linked to the rich mythology of the area and the pastoral life of its inhabitants the term Arcadia acquired mythical dimensions and is used to describe the simple, serene, rural life. Framing the basin

Utopian land Arcadia was glorified in the arts as a utopian land on earth; paintings, theatrical plays, but visual arts exalted the this Arcadian ideal. Expressing the Arcadian ideal, the painting of the shepherds by Nicolas Poussin (1638) is also named ET IN ARCADIA EGO. This phrase (I also was in Arcadia), written on a tomb, was given different meanings, either referring to the dead person or to death itself. In more contemporary expressions, in his homonym documentary the Greek director F. Koutsaftis (2015) argues about the importance of memory in a place as part of an identity search5.

In 1829, France organized a scientific mission in Greece, a research concerning the historical, geographical, archaeological and pictorial documentation of the country, which resulted in thematic volumes and an atlas. As pointed out by the Head of mission Bory de Saint Vincent, in the volume “Geography”, the natural landscape of a mountainous land like Peloponnese, has given isolated basins, which do not communicate with each other, resulting in the diversification of people in each place. The residents have peculiar customs, based on very different needs and interests.

Framing the basin

“Land is not a given commodity; it results from various processes.” From the one hand, it’s the spontaneous transformation, all geological and natural processes that contribute to the instability of terrestrial morphology. From the other hand it’s the human activity that turns land into an increasingly remodeled space. (Corboz, 1983, p. 16)

Agriculture mosaic The peasant landscape with the vast agricultural fields and pastureland had characterized the basin before the mining process started. Until 1970, the economy was based on livestock, mainly poultry and pigs, sheep and goats, and agriculture, with the traditional crops of the region: olive groves, potatoes, cereals, chestnuts, walnuts, sour cherries, apples, pears, vineyards and horticulture (NTUA, 1992). Agricultural production is directly related to the cultivable land that surrounds the settlements. The population depends on an economy based on the productivity of the territory. However, the agricultural production had limitations due to small land properties and low production that eventually led to an economic decline (NTUA, 1992). The Orthophoto of the area in 1960, on the right, shows the extent of Megalopolis at the time as a small settlement inside the different patterns of the agricultural land and the natural features: Alpheus River running from south to north and Helisson from east to west.

â&#x20AC;&#x153;This privileged link between nature and culture that is created in our society through landscape refers back to the significance that each cultural model attributes to its physical environment and to the place that it occupies on the scale of values in relation to its formal structure.â&#x20AC;? (Gregotti, 2009, p. 9) A direct relation between the city and its productive territory is developed, as shown in these images from the 1960â&#x20AC;&#x2122;s. The central square of the city is transformed into a street market to trade the local products. This relation has radically changed after the transition towards the industrial era of the area, but the weekly street market is still a vibrant event. Every Friday, the flea market in Megalopolis is an attractor for people that live in the nearby villages, as they come once a week to do their groceries, visit doctors and services in the city. The dependency of the villages to the city is mainly due to the current aging population of the former and the concentration of amenities in the city.

An archipelago of settlements The settlements in the basin have a long history of existence, under a story of population fluctuations and landscape alternations which demonstrates the strong dependency of the urbanization to the topography and the productive territory. In this frame, 71 villages are surrounding Megalopolis. Some of them are located in the relatively flat plateau and others on the slopes of the surrounding mountains. Currently the traditional villages

All the settlements faced a gradual abandonment after the 1960â&#x20AC;&#x2122;s and their image now includes many abandoned building shells as standing ruins or transformed into seasonal residences.

The city is structured based on the system of Hippodamus, with a grid of approximately 100x70m, covering an area of about 2x2km. The two main vertical axes, direction from NW to SE and from SW to NE, concentrate all commercial activities and they meet forming the central square. The social life of the city is taking place along these main axes and the square, but a series of other small scale formal and informal public spaces and amenities, attached to the grid, is completing a vague network.

The population of the municipality of Megalopolis and of settlements around changed radically in the transition period towards the industrial era. The decline in population of the surrounding villages does not directly link to the increase of Megalopolisâ&#x20AC;&#x2122; population, as people from other areas in Greece, specialized labor force, had been arriving to work in the mines. However, itâ&#x20AC;&#x2122;s due to the low productivity of the highland, the bad connectivity of the infrastructural network on a strong geomorphological terrain and the concentration of amenities in Megalopolis because of the start of the mining operation. (NTUA, 1992)

c. Dynamics of a productive territory

“Land could be described as having a horizontal characteristic (relief, cover and extension) while scape is vertical, dealing more with social programs (structure, activity and data). Land is more stable and less malleable than scape, which is created and destroyed through cultural tastes and acts.” (Berger, 2002, p. 151) A reading on the landscape of the basin of Megalopolis, both vertically and horizontally aims to show the changes over time. “Land, so heavily charged with traces and with past readings, seems similar to a palimpsest.” (Corboz, 1983) The ongoing geogenic and anthropogenic transformations of different periods on the earth’s surface are leaving their traces. These traces of different phases are still present today. The alternations in the different layers of ground, water, forest, agriculture, urbanization and infrastructure are continuous, but after the start of the mining process they accelerate in the center of the basin. What is the new landscape resulting from this acceleration? Mining is a disturbance in the smooth long-term changes, as it opposes a rapid artificial transformation to the original topography; and dominates transforming the existing systems.

[λόγ. < αρχ. κατοικῶ] Co-presence of different activities, time-space sharing

“What counts in landscape is less its ‘objectivity’ than the value attributed to its configuration. This value can only be cultural.” (Corboz, 1983)

The inhabitation of the territory over time projects its multi-functionality, the variety of activities that are coming together in the same space and form its identity. Ancient ruins and paleontological findings come together with the continuous appropriation of the forest and the mountains, the agricultural land and the pastureland, as well as with the contemporary urban tissue and the intensive mining activity. The appropriation of the different landscapes reveals the natural, archaeological and cultural territorial heritage which is not only a composition of spatial elements but also the constant use of the territory. “Space depends on scale and experience, exists as well as in the transition between the interior and the exterior, is inhabited by users; it does not exist without temporality.” (Verbakel, 2007) Various cultural and religious points, such as churches in the main square of each village, are containers of the social life. A vast network of chapels around the cliff tops are popular spots to visit during annual celebrations; while monasteries near the forest, in which a few monks or nuns live and manage their own cultivable land, are popular locations for people and tourists to visit. Furthermore, springs, fountains and monuments, spread around in the landscape, are spots where travellers and visitors have short stops to drink water or see the view or admire the nature (where annual ceremonies also take place).

Among the different activities hiking and hunting relate more to the forest and the mountains. Hiking in different times of the year, is organized mainly by hiking clubs and has different levels of difficulty, or it can even be organized individually. Multiple hiking paths surround the basin, such as the O32, which is 192km long and is one of the most coherent and well maintained National Hiking Paths that crosses Central Peloponnese, starting from Vitina on mount Mainalon (where it meets the long European path E4), crossing Lousios gorge and Karitaina, going through the basin of Megalopolis towards mount Taygetos. Hunting is organized in seasons of each game are defined by the minister’s annual regulatory decision, but in general, hunting is allowed from 15th of September until the end of February and is completely forbidden from 11th of March until the 20th of August. From 20th of August until the 14th of September is only allowed in areas designated as “Migratory Birds’ Passage”. Daily, hunting is allowed in the morning, half an hour before the sunrise and half an hour after the sunset. (Hunting guide, 2016)

The complexity of this coexistence is intersecting the mining area, which is sometimes enhancing and other times disrupting the continuities. Thus, there are fragmented and connected parts as well, such as the grasslands of the reclaimed deposits and the artificial lakes that serve livestock. The perception of being inside a basin is also defined by specific landmarks. The cooling towers, as contemporary landmarks, stand inside, in the center of the basin forming two orientation elements, while the surrounding mountains are defining the outerupper border of the basin, forming at the same time a geological landmark. In this timeless landscape, â&#x20AC;&#x153;the inhabitants of the land tirelessly erase and rewrite the ancient scrawls of the soilâ&#x20AC;?. The exploitation of the land is a process of landscape colonization even of remote areas with machinery and land becomes an object of construction, a type of artifact, a product. (Corboz, 1983)

This chapter explores lignite extraction as a process of expropriation and continuous alternations. The mining activity is a necessity for energy production in the national scale, depending on the exploitation of domestic resources.The growing open pit of Megalopolis transforms the landscape in multiple levels; therefore the logics of the machinery is constantly reformulating an artificial topography by extracting and moving material as well as changing the natural water flows. What are the systems generated by these processes?

Energy Production and Pollution Lignite is a type of coal which is considered as a low quality resource for electricity production. In the national scale almost the whole electricity production is based on non-renewable resources and mainly on the exploitation of lignite. Among them there is a considerable percentage of energy production depending on natural gas and oil. On the other hand regarding the renewable resources there is high potential in solar and wind power, as well as geothermal mainly on the islands. The Lignite Center of Megalopolis is contributing to the national electrical grid, which is organized in a central system (for the mainland)(G.C. Spiropoulos, M. Emmanoulidis J.K. Kaldellis, 2011), where all the Thermal Power Stations contribute with electric power. The “electrical grid is mainly supported by 15 major thermal power stations (TPSs)” (Kaldellis et al., 2009) Concerning the exploitation of lignite, the mining activities are related to major environmental impacts 0

for the regions; because of the intense activity of excavation transforming the topography changes the hydraulic gradient and produces pollutants, which affect the irrigation and water supply in the territory. In the list of “coal – fire stations with high health-damaging emissions”, Megalopolis’s TPS rates on the third place, this is a considerable factor for the scale of pollution and the impact on the local communities. (Coal Atlas, 2015) Additionally, the TPS of Megalopolis has a considerable higher contribution to SO2 emissions until 2008, compared to the large scale installations6 in the northern part of the country (G.C. Spiropoulos, M. Emmanoulidis J.K. Kaldellis, 2011) 6 In 2008 there were 16 active Thermal Power Stations (TPS) - units in the northern area of the country, compared to 4 units in Megalopolis. (G.C. Spiropoulos, M. Emmanoulidis J.K. Kaldellis, 2011). In 2011 two of the units in the Lignite Center of Megalopolis were closed. 500

Mining activity in systems

The process of the excavation of lignite produces deposits of infertile soil and lignite. The latter is collected in the lignite yards, where is distributed to the units for the combustion (burning of lignite), an activity which produces fly ash, CO2 & SO2 emissions. Fly ashes include significant portion of magnetic minerals which are transported through atmospheric pathways and deposited on the ground. Fly ashes from coal combustion contain very high level of trace metals, which is affecting the water supply and irrigation for the territory. (Sarris et al., 2009) 7 At this point it is important to mention that fly ash particles are considered by many experts as extremely contaminating, being also associated with respiratory and cardiovascular diseases. (Kaldellis et al., 2009) The remaining part of the fly ash (which is collected through filters) is disposed in landfill together with gypsum, which is also produced by the lignite combustion. There is already a reuse of the fly ash and gypsum as construction materials, by private companies but in a very short percentage compared to the disposal.8 7 In the same article it is mentioned that “Accumulation of anthropogenic ferromagnetic particles originating during high-temperature combustion of fuels (Vassilev 1992; Dekkers and Pietersen 1992) results in significant enhancement of top soil magnetic susceptibility.” 8 “Regarding the fly ash produced from Greek power sta-

In the current situation there are three units producing electricity, two of them based on lignite combustion and a new one based on imported natural gas. Concerning the advantages of this mining activity to the local community is the low cost heating system, which is provided by the combustion process.Taking advantage of the combustion of the lignite, the PPC provides district heating to approximately 500 households (TPS Megalopolis, 2015), which allow each family to save up to 40% compared to the heating based on oil consumption. Based on the potential in renewable resources for energy in the scale of Peloponnese, there are not many opportunities in wind power and biomass for the basin of Megalopolis. On the other hand, seeing the waste from all the stages of the mining activity, as well as the high level of pollution for the territory, energy system could generate new synergies and economies. In parallel regarding the lignite’s depletion9 in the next 25 years, the post mining landscape creates new dynamics, in terms of energy, becoming a potential resource for biomass and energy production. tions, the relatively high uptake abilities and the low mobility of toxic elements allow the use of fly ash in several applications such as adsorption materials, sewage treatment, land filling and cement and concrete production.” (Kaldellis et al., 2009) 9 “It is expected that the lignite’s depletion time shall vary from 25 to 50 years” , in the national scale (Kaldellis et al., 2009)

The annual amount of the water that is extracted from underground is 18 â&#x20AC;&#x201C; 20 hm3, while 14 â&#x20AC;&#x201C; 16hm3 is used only in the cooling towers. The 90% of the later is used for the cooling process, which is transformed to steam and evaporates in the air, (without returning to the surface as liquid). The other 10% of the water is used for other industrial processes related to the cooling tower, such as the cleaning of the filters. The rest of the fresh water that is extracted is distributed for water supply to the nearest settlements and for the industrial buildings as well as for irrigation purposes.

Human Pressure in the basin of Alpheus

Interruption in the natural water flow

The basin of Megalopolis is crossed by Alpheus River (one of the biggest rivers in the country) and is part of its catchment area, located in the upstream area.The intense human activity in the river basins is directly related to the high demands in water consumption. In the basin of Alpheus irrigation, industrial activities, water supply and livestock are the main consumptive uses10(Mihas et al., 2014) that require large quantities of water. The annual demand for water is up to 120hm3, from which irrigation and industrial use require more than 90% (Ministry of Environment & Energy, 2012). The demand for water is not equally distributed during the year, while it depends on the season and the number of rainfalls. Hence during the summer the demand for water is increasing, while the precipitation is much lower.

The intense extraction of fresh water especially during the summer period creates imbalances in the natural water flows. The steady rhythm of withdrawal from the aquifer opposes to the fluctuations of the water level below and above the surface. Characteristic example of this condition is when the springs in a higher level dry up because of the lower level of the karstic aquifer and they stop providing water in the main river of Alpheus. In this (not so often) case the PPC extract more water from the karstic aquifer to fill the springs artificially. Except the large amount of fresh water that is used for the combustion of the lignite, at the same time during the excavation process around 10hm3 annually is pumped out from the mines directly to the river. According to the official Study of Environmental Impact of the PPC the cycle of the natural water flow is maintained in balance, because of the volume of the water returned to the surface.

The extraction of lignite and the energy production in the basin of Megalopolis is one of the highest human pressures, in terms of water consumption in the area.This process demands high volumes of fresh water coming directly from the aquifer through a system of boreholes (around 130 – 150m deep) in the karstic aquifer, below the lignite beds.

Therefore, a question is raised about the quality of the water, considering also that the extraction area is located in the upstream area of the Alpheus river basin and therefore it affects the quality of the water for irrigation and water supply, in the territory. Could these large volumes of water be recycled or treated and return to the environment? It is a challenge and potential for a better water quality for the region and a more resilient system of the mining activity until closure.

10 ESTIMATION OF WATER EXPLOITATION INDEX PLUS (WEI+), “The total average annual abstraction, TWA, is calculated based on the average annual demand data, referred on 4 basic consumptive uses of water. In this category the hydropower production is not included and it is considered to be a non-consumptive use, while it returns to the environment.” (Mihas et al., 2014)

The agricultural land, not only in the local scale but also in the national scale is irrigated by 40% from public and 60% from private irrigation systems. In the second case the system based mainly on private boreholes and wells in each agricultural plot, which links to water withdrawal directly from the aquifer. In the

Concerning the annual precipitation in the area, the climate of the basin of Megalopolis, is mainly characterized as sub humid and cold, especially in the low plain. During the year more than the half of the volume of the annual precipitation is concentrated between October and March, while the 1/3 of the total precipitation is during one month, especially between autumn and winter. According to measurements being realized inside the mining area, for the year September 2013 – August 2014, the maximum precipitation of 248mm was in November and the minimum of 1mm in August. (Mines Environmental Department, 2014)

“Finally, the water sources differ radically between public and private networks. The public networks, mainly use surface water, while the private ones use underground water. There is a rising interest for artificial water reservoirs.” (EASAC) A characteristic example is the number of private boreholes in Western Peloponnese, where there are 14000 legal and 12000 illegal in total (Migkiros). “Although precise estimate of the available water resources in Greece have not been made, most authorities agree that water consumption and use constitute only a small percentage, less than ten and fifteen per cent of the annual precipitation and water potential, respectively.” (EASAC)

Regarding the overuse of fresh water from both industrial and irrigation uses, there is high potential in developing systems where the water could be collected and reused. The climate conditions in the basin of Megalopolis, in combination with the topography allow the design of water collection points depending on surface water (storm water and grey water collection) and the reuse of it for irrigation.

Megalopolis Mines | Mine Water Drainage The water management of the mines is based on surface water drainage system. The surface water is collected in different catchment areas by gravity through channels. Inside those areas there are floating pumping stations which leads the water through pipes directly to the river. The catchment areas are located in different levels and they change location according to the progress of the excavation. The quantity of the water which is collected in the catchment areas is mainly liquid precipitation which flows over the inclining surfaces of the mines, as well as underground water which meets the surface when the excavation reach the lower levels. The water is disposed directly to the river untreated, which contains lignite dust and earthen materials derived from the mining activity. There is only a periodical treatment during the year in the basins, where the water is collected. On the northern edge of the mines, in the open pit of Kyparissia, there is the main karstic aquifer of the basin of Megalopolis. Until 2010, due to the ongoing excavation process in the open pit of Kyparissia, it was necessary to pump out the water which was rising in the lower levels of the mines. Gradually due to the mining activity the level of the ground water decreased and while in 1992 the level was at +300m until 2005 it had reached the level of +285m. Additionally, there was an extra use of fresh water for the operation of three in total Thermal Power Stations, two of which were closed between 2010 and 2011. (PPC, 2015)

â&#x20AC;&#x153;In general terms, surface mine developments and underground mine workings below the phreatic level invariably changes the hydraulic gradient, thus affecting the groundwater and surface water flow regimes. As a consequence, flow of water may be induced from the surrounding rock mass towards the mining excavations which may necessarily require pumping large quantities of water and creating extensive and prolonged cone of depression.â&#x20AC;?

Earthworks - landscape alternations Land expropriation

1970 - 1980

1960 - 1970

In the starting point of the extraction the Public Power Corporation bought the first area to prepare the ground and the infrastructure for the upcoming mining and energy production activity (1960 â&#x20AC;&#x201C; 1970) . In each expansion the PPC was broadening its property (see fig. 00 - red lines) by expropriating new ground. The small scale plots owned by different farmers or local people were transformed to a large ownership. Gradually the mining spread over the vast agricultural land and the settlements, which were on top of significant quantities of natural energy resources. Another kind of production took place, transforming it from purely agricultural to the extraction of materials and energy production.

Alternations "Every mining expedition and reclamation project is a unique design scheme that relies on mappings of temporal landscape processes." (Berger, 2002) The extraction of the lignite and the deposit of soil are processes supported by a huge infrastructure of conveyor belts, which transfer the materials. A timeline between 2005 and 2015 is showing the different installations of the conveyor belts (red lines) according to the new lines of excavation. Along with that, a series of alternations is happening on the soil and water conditions, with expanding external and internal deposits of soil and new areas of water collection (water drainage).

Material movement Different types of machines are forming the different topographies and types of landscapes. The excavation process results in enormous holes on the earth’s surface: “monumental vacancies that define, without trying, the memory traces of an abandoned set of futures”. (Smithson, 1967) Smithson provides an example of a “jejune experiment” with white and black sand, discussing the irreversibility of a manipulative action on a certain ground. The opposite action cannot reverse the result; instead, it is increasing the entropy, escalating the same result. The manipulated topography is a distortion in the territory, the alien element of a continuously transforming landscape. The scale of extraction site is opposing to the one of the original landscape. Jackson (1984) discusses a new definition of the landscape as “a composition of man-made or man-modified spaces to serve as infrastructure or background for our collective

existence”. The extraction as a process of material movement in co-existence with all the different elements or traces composes the identity of the place, the “genius loci”. Evolving landscapes have a dynamic character inscribed in the way they are domesticated. The way the machines work; excavate, move and deposit materials is transfiguring the ground in a certain way. Corner (2006) in Terra Fluxus refers to Gruen’s description of landscape as a region “where human occupation has shaped the land and its natural processes in an intimate and reciprocal way”. Sharper or softer distinctions between the original and the artificial elements coexist in a shifting landscape. The machinery is transfiguring the topography resulting in embodied and displaced elements of scape being equally essential as shape (Jackson, 1984). Scape seen as an instant of topography is capturing the essence of all daily transformations of the mines.

Material Movement I:

The diagram shows the start of the extraction process for the different mines in different time. Extracted materials from the open pit mines are being transferred to the lignite yards and to the external deposits, gradually forming hills. From the yards, there is a continuous flow of lignite towards the units, for the combustion. After this process, the byproducts of fly ash and gypsum are moved from the units and being deposited in a landfill. The schematic NS cross section shows the original topography of the area and the different mines and lignite beds.

Therefore, land has a form, or better is a form (Corboz, 1983); a wound of strong linear geometries and softer deposit patterns, different figures that derive from the machinery which is transforming the landscape. On a wider scale, this metamorphosis includes the images generated by functional exploitation – images that can be apprehended through an adjusted level of our perception, caused by the same technological process. (Gregotti, 2009, p. 7) The various processes are leaving traces on the irreplaceable surface of the soil. “The designation terra firma (firm, not changing; fixed and definite) gives way in favor of the shifting processes crossing through and across the urban field: terra fluxus.” (Corner, 2006) The composition of these elements in time and space reveals each contemporary image of the landscape.

The current topography: interpreted in shades of grey, from the darkest the deepest to the lightest the highest point, the current manipulated topography of hills and holes in the ground is expressed in this map. The conveyor belts that transfer the material and the dirt roads inside the mines are the essential infrastructure for their function and contributors to the formation of this landscape. The map is a projection of an instant topography, of its formation during the first semester of 2016 (Data: Google, DigitalGlobe) Cartography and spatial analysis by the authors.

As the sculptures of Alexander Calder, the aforementioned transformations incorporate motion in a balance. The static matter is opposed to the constant movement. The composition of linear infrastructural elements and the areas they transform create a territorial sculpture, which always in motion. “The sense of motion in painting and sculpture has long been considered as one of the primary elements of the composition.” (Alexander Calder, Modern Painting and Sculpture,

exh. cat. Pittsfield, Mass.: Berkshire Museum, 1933), 2–3.)

“Also there is the possibility of using motion in an object as part of the design and composition. The sculpture then becomes in one sense a machine, and as such it will be necessary to design it as a machine, so that the moving parts shall have a reasonable ruggedness. Even those sculptures designed to be propelled by the wind are still machines, and should be considered thus, as well as aesthetically.”

Systems located "Like an operation system, its software and hardware come in the form of points, patches, or planes of interventions or as networks and zones of influence, sometimes fluid or fragmented, gradual or temporal." (Belanger) Visible and invisible sets of movements and flows are generated through the dominant mining activity. Flows of energy, material and water intertwined with the smaller scale systems of the settlements in territory. Surface and underground infrastructure create a network to serve industrial and domestic demands.

Operative territory in sections Starting from the mass material movements and the large amount of fresh water, extraction of the lignite and electricity production, the mining activity could be seen as a closed industrial system, where energy, soil and water have been overexploited. In all the steps and phases of these processes, there is waste produced that could be seen as a dynamic for a new system. How could the waste of each system generated by the industrial activity, be a potential for the territory?

A reading of the current networks could lead to design strategies for the creation of more resilient systems, where more demands could be met, without overexploiting the non-renewable resources of the landscape. Through a frame of until and after closure phases, the proposed design strategies explore the dynamics of recycle and reuse the existing waste of the systems of energy, soil and water.

Until Closure Along with the excavation of the lignite and the energy production, the flow of energy, material and water alters through the design strategies. Remediation processes for the contaminated and weak soil, prepare the ground for alternative agriculture. Circular economies are generated, completing the chain from production to processing and to the market.

Legend of the phasing diagrams.

Capturing a moving landscape “For a landscape to be properly recovered it must be remade, designed, invented anew; it cannot simply be restored, as an old painting.” (Corner and Balfour, 1999) The design in this scale focuses on sculpting a “tableau vivant”, capturing the future alternations of an operative landscape, an inhabitable productive territory. Following the dynamic processes of topographic reconfigurations until the closure of the mines, the phasing is directing the creation of a new ground. Part by part, the recomposition of the landscape is taking place in a fine grain of movements and strategies applied in different places and in different times. The moving future landscape is projected phases, in a series of diagrams, which anticipate the transition towards a post-mining era. “Landscape, as seen through the practice of reclamation, is grounded in both the mechanical and the organic models of nature, both of which are derived from these modernist conceptions and views of nature. Reclaimed natures may be technologically constructed and evolve organically (and vice versa). Nature is a curious union of the machine and the organism in reclamation.” (Berger, 2002, p.182) The design aims to articulate all the different elements, sharp and soft geometries of the topography which are complementary or in juxtaposition. Establishing a dynamic composition in balance, the current infrastructure is used to form the future landscape. The same machinery that shape the current topography in particular slopes and plateaus are used to organize the proposal. Strong geometries and unfolding soft patterns compose the future machine-made landscape. Material movements are still re-configuring the territory, as the exchange among the different areas is going on.

2100_ natural succession Nature has conquered the place. The injured ground of former open pit mines and the polluted external deposits are now wild life sanctuaries. A natural biotope has been gradually formed on the ground level of the former mines, as the groundwater reclaimed its pre-extraction level. The area is an attraction to hikers, tourists and locals, as multiple divers landscapes come together. Megalopolis 2100 is an agro-polis and its population has doubled since 2050, when the mines closed and new economies were established. After the long-term lignite industry, the local economy is based on biomass energy production and agriculture, livestock and bee-keeping. Circular economies tie to traditional ones and relate to the productivity of the territory. Crossing ecological corridors connect the forest through the basin and the continuity of pastureland and herbaceous vegetation form bee and sheep-corridors. 122

2040 By the time lignite is over, new spaces are reclaimed. The abandoned industrial buildings serve educational, recreational and research purposes (museum, Environmental Education Centre, Institute of Agricultural Studies) gains more importance. New programs inside the mines are introduced, as in the public spaces of the arena as an open air concert hall and the crater, an open air museum in the deepest part of the left over mines. The infertile internal deposits produce biomass with the cultivation of energy crops, while the former lignite yards currently store the yield of bio-crops before processing or water for irrigation. Reforestation n combination to the silvopastoral system increase biodiversity on top and above ground. 126

Re-cultivating the land includes both traditional and new agriculture. Olive groves and vineyards are on the formed plateaus while crop rotation is necessary. Agroforestry is combined with small scale crops; eucalyptus forest is partially replaced by agriculture in combination with solar panels. The separation and treatment of grey and black water projects new possibilities for irrigating the formed agricultural land. 128

2030 The reconfiguration of new agricultural land is also possible by adding top soil on an infertile deposit. Reforestation on the slopes is the first step to create more stable ground, shaping the plots . At the same time, the introduction of plant nurseries supplies the cultivable land. Artificial wetlands purify the waste water of the city and a retention pond is storing the treated water in order to irrigate non edible crops. A variety of crops is introduced, traditional and new ones, while the agricultural plots are being downscaled. The reactivation of existing public spaces along with bird incubators are additional programs on re-cultivated areas. District heating is an advantage provided to the locals from PPC, and completing the network of the city is already a target. 130

2020 The potential for biomass is even clearer by the introduction of energy crops (high yield bio-crops) on the finished deposits of infertile soil. The energy crops donâ&#x20AC;&#x2122;t have many requirements in soil and water conditions and are directly highly productive. Additionally, agroforestry with eucalyptus plantations offers many years of harvesting for biomass. The underused or abandoned urban potential connects to the deposits. Reactivate the public space on the external deposit of Psathi, the balcony towards the city, offers multiple uses such as sports activities and recreation, hosting annual celebrations. The currently abandoned train station is a community cultural center and the rail road transforms into a pedestrian and cycle route that connect to the nearby villages. Starting the network of bio-swales on the grid of Megalopolis allows the utilization of storm water for irrigation and livestock, while until the closure, providing water for the cooling towers from the collection and reuse of pumped out water from the excavation sites in order to release the pressure from the aquifer. 134

2017 The importance of topsoil is crucial at this point, as in order to retain its fertility, separation is required. A former deposit serves as the topsoil storage area. Using the existing conveyor belts, the extracted top soil is transferred and deposited, while low vegetation is used to keep it fertile. The organic matter of soil is enriched by cultivating cereal crops and leguminous plants, which are used for fodder. In parallel, the excavation processes divert Alpheus, but this diversion is reformed to slow down water by enlarging the riverbed of the river slowing down its speed, forming a collection point of the lignite sediments from the pumped out water due to the excavation processes. Reforestation on the slopes stabilizes the ground and establishes the structure of the new agricultural land, increasing at the same time the biodiversity of the already reforested areas. Pedestrian and cyclic routes start from the two main axes of the city. 136

The olive groves are the dominant crops and essential elements of the landscape. Olive tree as landmark represents both cultural and economic characteristic of the basin. At the same time the road infrastructure that connects the biomass plant and the fields of biocrops becomes a powerful connection. It creates a potential ground to strengthen the existing economies (honey production) or generate new ones (wineries). Due to the topography formed by the machinery, storm water is collected in retention ponds and is used for the irrigation of fields, with higher demands in water, such as vegetables. Next to the agricultural plots, there are seasonal pop up markets, where farmers sell local products directly from their fields.

Olive Grove The area is located on a hill between the city of Megalopolis and the mines, formed in levels and slopes, by the mining activity by depositing infertile soil mixed with top soil. Currently grassland is the main vegetation with scattered trees and livestock as well. It is a dynamic crossing, concerning the connection between the biomass plant and the fields of energy crops. In the first phase, the area becomes the storage of the top soil where it is maintained fertile. After a series of operations for the stabilization of the soil and the distribution of the top soil to other potential agricultural areas, it becomes an active part of the productive land, as well as the social life of the territory.

Energy Crops This zoom is part of the larger fields of biocrops based on the topography of internal deposits. Its role is crucial in the development of the production in the territorial scale, by transforming an infertile deposit to a productive land. Following the forms of levels and slopes the currently grassland turns into a colourful canvas which is changing through time, in terms of colours and different types of crops. Starting from a mixed pattern of pasture land and energy crop fields, it changes into an extended field of crops cultivated to produce energy. Afterwards agriculture expands creating a mixture of bio and edible crops.

Conclusions The questionable future of a brown coal mining area projects many challenges and threats. This transition towards the post-mining era also requires a change on the mindset of the residents and the visitors.The image of an area widely known as an intensively industrialized and degraded place changes gradually in time as a multiplicity of uses and publics are coming together. Recreational, cultural and productive composing elements co-exist in the center of Megalopolis basin. “…the balance between different poles is a planning challenge, as developing post-mining landscapes always means dealing with a lost home : how much history does the new landscape need? What elements and ordering principles will be taken up again, which will be reinterpreted, which complemented? ” (IBA FurstPuckler-Land 2000 – 2010) The history of the future of a post-mining territory is inscribed into the phasing and the systemic character of the project. Elements of different phases structure a multilayered landscape that shapes the future of the region. The continuous relation between the city and its productive territory is reformed through the years, but not interrupted. “This gives rise to a possible vision and therefore to a combined approach ‘through bricolage’ of the found elements, considered as a concrete formal universe that was modeled by juxtaposition or collage. This gives the discontinuity of the elements – at the various levels of complexity of their dimensions and contiguity – its own capacity as a structuring presence.”(Gregotti, 2009, p. 15)
