preface

Nowadays the whole world is facing the problems of depleting crude oil resources and negative effects of climate change. We are at the verge of fossil fuel era, facing the energy transition period. Denmark has ambitious plans for diminishing the C02 emission. Country is planning the change in multiple scenarios, trying to predict probable trajectory of transformation towards green energy. The aim of the change is to cut the dependancy on fuel providers. Therefore the new energy potentials are investigated. The sources are to be based locally , the country is to be more self-sufficient. But transition is to affect the way our landscapes are going to look in the future. The choices that we are making now are to ifluence spatially our lands. The new form of energies like windmills or biomass plantations has specific characterisitcs that change our surroundings. We should plan them conciously.

Motivation for research topic The preliminary research for my Master thesis has taken place in Spring 2015, during my practice at H+N+S office ( Netherlands), next to the exchange at Amsterdam Academy of Architecture. One of the founders of the H+N+S Landscape Architects– Dirk Sijmons, together with fellow-workers released the book in 2014 , titled : ,, Landscape And Energy - Designing Transition”. The office itself was involved in a few projects related to spatial implications of the energy transition. Being the part of the H+N+S for a half of year, I was preparing the biomass research, as the potential toolbox for the Dutch Energy Line project. The aim of the study was to research the potentials for green energy use in the historical defensive line, running across Netherlands. Preparing the booklet on the various biomass plantations made me realize the abundance of spatial combinations this type of land use give to us- Landscape Architects. What is more, it draw my attention to the sustainable green energy goals, which should not only focus on plantations productivity, but also, strive for social and ecological goals.

Infrastructure corridor as green energy landscape After I got back to Denmark I was motivated to further study the topic of green energy plantations and their role in the transition period. I was interested in the opportunities and challenges this kind of plantings give to landscape architecture practice. In the context of Denmark, where lands prices are high, switching from the other land use would be an unrealistic. That lead me to search for ,, leftover’’ spaces, places of unused potential. As a result of talk with Anders Busse Nielsen and Alexandra Vindfeld Hansen I decided to focus on margin lands along infrastructure corridor of new railway connection #Fig.1 Green energy + landscape of infrastructures

The Climate and Energy minister - Lars Christian Lilleholdt just before conferenece introduced changes in the Danish policy, cutting back on climate aid and lowering CO2 targets towards 2020 . That decisions did not escaped the attention of NGOs that ,, awarded’’ Danmark with ‘Fossil of the Day’ during COP 21 ( CPHpost, 2015). Right after Paris conference Ministry of Climate and Energy got back to the previous climate goals. What is the binding statement of the Danish policy?

Finger plan - GREEN adjustments ? Finger Plan is strategy for a development of the metropolitan area of Copenhagen which was published in 1948. The whole master plan is transit oriented. Copenhagen with it s dense areas is represented by the palm. Fingers are residential and business development areas allocated by the S-train. The consistency of the development is guaranteed by interlaced green wedges, which serve as green belt to urban sprawl. Their important role is to

ensure the equal access to recreation for Greater Copenhagen Area. What is important ,Finger Plan, even after more than 50 years of operating, is still seen as an important part of regional planning. It is kept up to date with the most important changes in the national policy. One of the important question marks in the plan is Ring 5 transport . It is suggested to be canceled by some of the polititians. There were few reasons which argue for deny the merit of building the new highway. First of all it is constituting the threat for the environment as it was passing through Nature of high importance like: Store Dyrehave, Kirkelte, Mølleådalen together with Værebro Å. Secondary it can be assumed that introducing new highway can be the reason of induced traffic. It is of both: commercial goods transport and personal commuters. The latter to be direct reason of urban sprawl.

How would that affect the regional planning? Is cancelling of Ring 5 a chance for enhancing or even creating new green wedges? What is the new use for the infrastructure corridor? Right now as a genral rule the green wedge are excluded from the green energy instalation like solar panels or windturbines. Should the planning be adjusted in that matter? Are the infrastructure corridors and green wedges the potential sites for green energy

development? Revision of the Finger Plan is needed once again to keep it up to date with changing national politics. Decisions are made by Minister of Environment, so protection of natural resources are placed in front of the GDP. Is there a potential for the new policies that would support new green land uses together with green energy production? # Fig.6 Finger plan – probable planning policy adjustments 20.

Region Sjælland - strategic development Region Sjælland was the first region in Denmark to prepare the regional climate strategy.The main issues and aims tackled in the strategy for years 2015-2018 are: ENERGY AND RESOURCES:towards more renewable energy and better use of resources TRANSPORT: towards sustainable and commuter friendly transport and infrastructure CLIMATE ADAPTATION: for adaptation to climate change in rural, urban and coastal areas. (Regionsjaelland.dk, 2015) Strategic development of the whole region seems crucial for the clmate resiliance. Decentralized, bottom up initiatives are important but can be significantly strengthened when implemented in the coherent strategy. Main goals of the strategy indicate the need of the improvements in the transport infrastructure sector. Is there a possibility to ‘‘ kill two birds with one stone” and combine it with the renewable energy sources? How can the ambitious goals be implemented spatially?

GREEN STRING CORRIDOR

The Green STRING Corridor project is joined cooperation between the Region Zealand and The Capital Region of Denmark together with international parties of Region

Skåne, Øresund Region, Schleswig- Holstein and Hamburg. It is important intiative

for transport industry, aiming to reduce CO2 emissions. The Green transport corridor has the goal to diminish the connection time and in that way reduce the energy

consumption. By promoting and optimizing rail freight as green transport mode significant fossil fuel use can be achieved. In the so called ‘‘Business as usual scenario” the emissions of CO2 can account for 4.5 CO2 mil. tonns/ year, while in ‘‘Best case scenario”, the emission is targeted to 1.4 CO2 mil. tonns/ year

( Stringcorridor.org, 2014). All those improvements are of importance. We are dependant on the transport of goods, and strategic development of region is related to its physical connections. Therefore the implementation of coherent strategies and improved logistics have the biggest chance for achieving fossil fuel independancy.

The efficient use of resources and innovative solutions are to be implemented both for rail and road transport fullfilling the connection green goals. Does efficient use of resources and implementation of innovative solutions refer to the

infrastructure or transportation modes only? What does‘‘green’’ mean spatially? Can we improve the use of infrastructure corridor related margin lands? # Fig. 10 Green String corridor - international infrastructure strategy 25.

edgelands potential

never ending edglands line Infrastructure main goal is to support network for transportation, effective connection between the destinations. But it has its spatial imprints. Landscape of infrastructure is often decribed as transition, disconnected margin land. Its phenomenon is spotted by more and more authors. Reading the book by Michael Symmons Roberts and Paul Farley (Symmons Roberts, M., & Farley, P. ,2011) or experiencing the works of Edward Chell ( # Fig. 11), You quickly realize it is also our contemporary landscape of opportunities. Its linear connecting character has the potential to bind together long kilometers of land. How can we design the infrastructure landscapes so they use their potential (productive, social and ecological)? How can we make them coherent and serve as a multiple connections stretch instead of dividing edge? What role can they play in energy transition period? Can they help to build the awareness about the changing landscape in post fossil fuel era, where energy production starts to be visible instead of hidden in the backyards of our industrial sites? There is always a great tension on the edge. Can it translate to green energy production?

Transition TOWARDS MULTI green eNERGY Transition from one energy source to the other is not a new phenomenon in human history. We have been shifting from fuel wood, to peat, than coal to finally get to oil and gas. What is characteristic the fuels we used were more and more efficient , our population was growing, and so did our demand for energy. Today we are living at the times of so called ‘’ oil peak’’ and we question ourselves- what is next. Limiting the use of energy in our consumer market world or stopping the developing countries from our ‘’mistakes’’ is rather hard to imagine. We talk about transition from black sources energy towards green, less harmful for the environment, but what really makes transition unprecedented in the history is the change from MONOfuel based system towards ‘’MULTIifuel based system. It is this approach that makes as less dependent on one source of energy, but also less reliant on the ruling energy suppliers.

#Fig.11 Danish energy mix potentials

bio energy + WIND ENERGY Danish energy policy has a long lasting tradition and had been started to develop already after the first oil crisis in 1973 (Danish climate policy plan 2012). Nowadays Demark is planning the transition in multiple scenarios. Politicians, researchers, economists- professionals of different backgrounds studied most promising national energy resources for renewable energy potentials. The most probable energy mix for Denmark is the combination of windmills ( especially those situated offshore) and biomass (State of Green 2015; Green Peace 2014; The Danish Climate Policy Plan 2013). As country is planning to be fossil fuel free towards 2050, green energy will replace 100% of black energy sources. In the transition period CHP power plants will gradually phase out coal and replace it with biomass. As it is stated in the policy plans biomass should be obtained from sustainable producers. The prices of the land in Denmark and generally in Europe are high and that results in high prices of the biomass itself . Therefore fuel is to be shipped all the way from North America . The import solution, eventhough decreasing the country CO2 emissions, still leaves much to be desired. Is there a possibility to grow biomass locally? 31.

Extracting biomass from the forests can have its negative impacts on the biodiversity (especially dead wood extraction), therefore it should be conducted in sustainable way. Is there the other way to enhance the local biomass production ? Agricultural use of it is more profitable and biomass plantations themselves consume a lot of space. How we find the way to overcome those obstacles? Is use of margin lands - like the left-over spaces of infrastructure corridors a chance to enhance the energy production?

investigating LANDSCAPE ARCHITECT’S ROLE IN ENERGY TRANSITION One of the starting points for the thesis topic was the question of spatial implications of energy transition, meaning : how actually our willingness to switch towards green energy can influence the landscape we live in? With the thought: ‘‘If everything exsist within the landscape then landscape architects must learn to design everything’’ (Benyus J. 2008), I started to investigate topics which are not traditionally within the scope of landscape architecture, but having a great influence on how we shape our landscape. Infrastructure / Transport theme research stressed the need for the improvement within

problem summary

transport corridor vs landscape Transport infrastructure in the landscape acts like disconnecting, single- purpose corridor, striking to maximize its capacity, only by improving its performance and getting rid of any possible conflicts on the way. The adjacent areas are lacking identity, have no clear function. Disturbed by infrastructure corridor are acting like separated edgelands. The ecocorridors are suffering from separation. There is no human scale. The maintenance of the areas is limited to the necessary minimum.

vision

green energy corridor enhancing landscape The new vision for infrastructure corridor is looking for synergies of green energy production and landscape experiencing. ‘‘Green Energy Line” aim is to use the potential of disconnected edgelands by proposing combined functions landscapes, causing interaction rather than marginalization. Introducing green energy plantations along corridor has potential to add identity to the site and at the same time have capacity to adjust to exsisting context. Their dynamic character is of great value, for always changing land use mosaic along

transport corridor.

Development of the site specific guidline on how to implement them in existing landscape would be needed.

planting strategy

After preliminary research of background themes, summarizing the problem and outlining the vision, further investigation of energy plantations using the potential of edgelands became the basic research topic. In order to prepare a toolbox for further site specific design, different species needed to be examined upon main objectives of planting strategy. The main objective was to choose the species that create the oportunity to work with green energy topic. That was considered on different levels, with sustainable goals in mind. The length of rotation time with influences on both productive and ecological goals, fuel properties influencing mainly productivity and ability to build the public awareness about the various energy plantations focusing on sociological goals were distinguished. Next various constratints resulting from infrastructure corridor specifics were studied. The themes of various soil and climate conditions were compared. Accessibility aspect and related harvest restrictions played important role in considerations. They are essential for the project to become feasible and cost-effective. Plantations need to be adapted to various contexts. As secondary objective planning perspective was taken into consideration. As the future may be developed in multiple scenarios minimum and maximum actions were considered to give the image on how our political decisions can influence the vision. The minimum scenario strive for adapting to the occuring negative impacts, whereas the maximum scenario join adaptation and mitigation strategies in one coherent system of interdependant actions.

Last but not least amenity values were considered. Human percepton of the landscape was important evaluation point. Ecological goals can not be omitted for sustainable green energy production. Therefore wildlife considerations were playing important role as well.

summary Green energy production is the main objective of proposed planting strategy. The species selection is based on few criterias: ROTATION LENGTH decribing the harvest period, having the influence on the management practices and visual appereance of the stand; FUEL PROPERTIES focusing on the moisture content and wood densities of different species, helping to distinguish the high and poor quality fuel PUBLIC AWARNESS describes the species selection based on the cultural tradition of fuel wood production, which has the potential for urban / recreational areas, for involvment in participation projects

Energy figures will vary greatly depanding on the moisture content of the wood. Softwoods ( conifers) with moisture content even around 55-60 % would need seasoning and still, because of the wood density, would be less energy efficient. At 30 % moisture they will deliver 10-11 GJ/t whereas hardwoods at 30% moisture content can deliver around 15 GJ/t. That makes hardwood interesting buisness case for edgelands to produce better quality fuel.

summary Planting strategies are discussed in the perspective of planning and policy advancement. Depending on the future scenerio plantings can be more or less advanced in the ecosystem services they provide. In the least developed scenario role of the planting will be limited to Greening , which is envisioned as something that is nice to have , amenity. More advanced scenerios planting strategies will strive for adaptation to occuring problematics ( PHYTOADAPTATION; phyto = latin for plant) and mitigation, where they will aim to prevent the negative impacts (PHYTOMITIGATION). The most developed scenario will work with PHYTORESILIANCE , which will aim multiple ecosystem services for both adaptation and mitigation to the oc-

advancement of planting strategies in different Danish 2050 scenarios The advancement of implemented planting strategies would be dependant on the political Agenda. The problem could lay in the so called ,,Path dependancy” where decisions made by planners are made primarily based on the already tested, historical practices. If Denmark wishes to continue green growth development the focus on sustainable green energy sources should be implemented in the spatial planning policies.

summary Development of planting strategy at regional scale requires careful observation and analysis of the site and adjacent nature areas, in order to enhance existing ecological structure,rather than constituting a threat to it. The basic criteria was set up and include among others: - adjustments of species to the habitats - use fo native species - diversity of stand age structure - limited use of species affected by pests - limited use of exotics species

ecological values

Considerations about Energy Plantations influence on biodiversity was studied. The basic guidlines for energy plantations implementation were listed. Native species selection was supproted with Environment Ministry Lists.

ENERGY PLANTATION AND BIOdiversity

For sustainable energy production the balance between ecological, productive and sociological aspects should be maintained. Most of the modern biomass plantations, are simillar in principles to the intensive form of agriculture. They strive for maximum energy productivity, introducing vast monocultures of single species like Salix, Miscanthus or Populus. With help of fertilizers they are able to achieve up to 20 odt/ ha. At the same time they are like other monocultures - prone to pests and diseases, easy target of wind throws. The basis for the research in the matter of ecological aspect of energy plantations was set up by the Nordic Council of Ministers publication titled:Increased biomass harvesting for bioenergy: effects on biodiversity, landscape amenities and cultural heritage values ( Framstad, E., et al.2009). To summarize I list here some of the most important guidlines to increase biodiversity : - limit the nutrient fertalization, - avoid very big sizes of the new plantations, - avoid planting in protected areas, - adjust plantings to landscape biotope, habitat, character - use diverse maintenance rotations, diversify harvest years, - harvest when the soil is frozen, - use native species, especially in the edge zones - connect new plantation to already existing green structures - plant few different varieties and ideally of different genders in the same energy plantation One of the important conclusion of the text is also the successional change that new energy plantation introduces to the landscapes. The change unused, marigin lands next to the infrastructure corridor can have positive and negative impacts on the diversity - all depand on the study of exsisting habitats. It is important to adjust species selection to the character of the landscape ( open /close, sunny/shady, dry/wet, early/ late successional state) so it enhance the ecological values of the site.

energy plantations typology

TYPOLOGY BUILDING BLOCKS landscape character

This sectionâ&#x20AC;&#x2122;s aim is to summarize the various issues tackled in the chapter of

infrastructure constraints

policy / planning strategIES

Species selection. It is to be achieved by organizing different planting strategies into energy plantations toolbox. The tool is to be used along the process of site specific design. The Toolbox consist of two tables: - shorter rotation periods energy plantatings - longer rotation periods energy plantatings The final typology is based on the intensity of the maintenance, as the length of rotation time affects productive, ecologic and social aspects of the design. That means that management practices within the stands are to play important role for both sustainable green energy production and the way landscape is experienced. What is more rotation time helps to adjust it according to the

energy planting

infrastructure site constraints and enable to work with various time spans for planning processes.

green energy production

All of the plantations are assesed according to landscape experince criteria and green energy production.

rotation length The tables are to highlight the abundance of the possibilities , which this type

yield

of mulifunctional planting may add to landscape architecture profession. As they are to serve different functions and are to be adapted to the different site specific conditions the choice

should fulfill multiple objectives.

Therefore typology is not prioritizing. The selected plantations are neither only the most productive one nor the most visually appealing. The aim is to show the multiple possibilities, which aftewards are to be used according to the specific site problematics.

Even the most productive species selection will not be effective if supply chain of the plantation will not be efficient. Because of

infrastruc-

ture corridor location some operations will be limited. Therefore the typical

activities should be adjusted to the restrictive character of the area.

Following steps in the supply chain have been studied and short guidline summarize the prodecedures that should be followed to make green energy production in the marigin lands viable and possible. Following steps summarize site characteristic constraints in the management strategy that underpins species

Rotation period of the plantation will have a deciding role in the specific area of the Infrastructure corridor. Due to limited accesibility and safety reasons longer rotation should be prioritized over the short. Quality fuel of lower moisture content and higher density is prioritized.

Harvesters with crane arm would be necessary to work on the slopes. The arm reach o 10 meters and access road of 2m should be provided. In the wet areas specially adjusted machines need to be used. For multistem species adjusted harvester head is a a necessity.

Processes of harvesting extraction, storage and comminuting should be make as efficient as possible. Combining opration is to be favourable for both economy and safety. Cut and Chip Harvest System would be the best businees case for infrastructure corridor are it shorten the supply chain , by cutting the need for storage. In that way coming back to the site for seasoned wood will not be be necessary. Interruptions in infrastructure corridor will be reduced.

Transport is the part of the supply chain which has the highest cost (over 50%) and therefore have to be carefully planned. To minimize the fossil-fuel based trucks in transport we should strive for usage railway freight.

Storage of wood logs along infrastructure should be avoided, because of limited accessibility. Therefore high moisture content wood ( like conifers, Salix) should be avoided in placess of limited access. Storage of woodchips is of big importance for fuel quality. Where possible existing facility should be used.

use existing capacity

The biomass power plants are distributed almost evenly along the infrastructure corridor. Using the the closest capacity make the supply chain ever more efficient.
