Abstract: Compared to other countries, in Germany landscape planning was developed early and has many variations in different federal states. This has generated many experiences with different planning arrangements. Additionally, it makes Germany an interesting example for learning about the strengths and pitfalls of landscape planning under certain framework conditions. The objective of this paper is to describe the system of German landscape planning, its development and its features in the context of governance conditions. The method applied for this purpose is a literature review.

An important milestone for landscape planning was its inclusion into the Federal Nature Conservation Act in 1976. Here, landscape planning was established as a precautionary planning, covering a broad range of natural assets and spatially specifying the general legal objectives of nature conservation and landscape management. It turned out to be effective for the inclusion of environmental concerns into spatial development. However, landscape planning could not halt strong driving forces such as urbanization and intensification of agriculture.

The specific form and implementation options of German landscape planning can be explained by (i) a governance context with rather strong legalization and respective boundaries for public participation; (ii) by the constitutional barriers to unlimited use of private property and (iii) by a federal system with an unbalanced distribution of competencies between planning tiers. For enhancing the effectiveness of German landscape planning, recommendations are deduced, which include, for example, better access to and homogenization of the information in landscape plans. Furthermore, links between planning and implementation instruments should be strengthened.

1. INTRODUCTION

German landscape planning can be compared to a medical doctor. She or he points out the strengths and weaknesses (illnesses) of a human body and tells the patient what the therapy should be. It is well known that not all advice from doctor’s is welcome. More specifically, people often do not like to hear that it is necessary to change their behavior or give up pleasures such as smoking or eating meat. In this analogy, the patient and their surroundings represent the decision makers who gain information about the state of the environment and have to decide whether to implement the proposals in spite of unpleasant financial demands and the consideration of

(3)

lobbies. Therefore, it is not surprising that landscape planning is not always welcome and loved. Even without statutory power, the information transferred often limits the decision scope of politicians. Nevertheless, landscape planning is needed more than ever because there is no other comprehensive environmental planning in Germany which deals with the full range of landscape functions (or ecosystem services) to be safeguarded for the public by governmental institutions (Von Haaren, Christina et al., 2014). This also means that landscape planning focusses on landscape functions which are relevant for supra-individual interest. Nevertheless, primarily in the context of implementation opportunities, landscape planning also deals with services that are defended by private interests and traded on markets (such as the suitability of the ground for construction of buildings).

This framing gives landscape planning an important role in the interplay of different sources, which inform political decisions about spatial development.

Due to obvious environmental problems because of enforced industrialization and intensification of agriculture (Deutschen, 1961), comprehensive landscape planning was included in the German Nature Conservation Act as early as 1976. Already then, landscape planning was conceptualized as an overall environmental planning method going beyond purely the convergence of habitats, species and landscape aesthetic, but to also include natural resources such as soil, water and climate. Landscape planning presents information and objectives, which on the one hand have to be considered by any sector for land use related planning (see Section 3), and on the other hand, landscape planning bundles information and objectives from sectoral environmental planning (such as water resources planning), in order to create a consistent information basis for spatial planning on different scales, for instance for Environmental Impact Assessment (EIA), Habitat Directive plans etc. In most German states, landscape planning does not result in mandatory measures. However, by revealing information to the public and to the decision makers in local and regional planning, landscape planning seems to enhance environmental compliance in decision making (Gruehn & Kenneweg, 2001; Reinke, 2002;

W Wende & Walz, 2017; Wolfgang Wende et al., 2009; Wende et al., 2012). Municipalities with a landscape plan have, for example, on average a higher proportion of natural areas, a higher density of wooded ecotones and better grassland preservation in comparison to municipalities which have not set up a landscape plan (W Wende & Walz, 2017; Wolfgang Wende et al., 2012). Implementation of landscape planning objectives is supported by implementation instruments such as the German impact regulation (demanding for offset/compensation of lost landscape functions) or the Habitat Directive. Metaphorically speaking, these, especially the latter, lurk in the background and motivate decision makers to seek safe solutions, which will not cause conflict with NGOs or the European Court of Justice.

However, the power of information also makes landscape planning often unwelcome. More importantly, mere information cannot overcome strong driving forces such as the drivers for land consumption and urbanization.

Therefore, in the federal system of Germany, discussions are ongoing for whether landscape planning with mandatory objectives (like in the state of North Rhine-Westphalia and city states) are the best and most effective solution for nature and landscape conservation. Altogether, the diversity of solutions triggered, not only by the federal system but also by the diversity of problems in the drivers and in some areas the densely populated landscapes, makes Germany a good example for studying what landscape

(4)

planning can be in terms of theory (explanation for scope and approaches in a specific governance context), methodology and implementation. These experiences might be useful for other countries introducing landscape planning in the context of the European Landscape Convention (ELC) or countries discussing the pros and cons of introducing environmental planning.

Against this background, the objective of this paper is to explain German landscape planning:

– by a short description of its historical development, highlighting some particularly important events and ideas (Section 2),

– by an overview of the current landscape planning legislation (Section 3), and

– by an explanation of some of its characteristics by the governance context in terms of legal and administrative preconditions (Section 4).

Concluding remarks (Section 5) will point out development opportunities if the present limitations presented by the governance context could be overcome.

The paper draws mainly from German literature, as very little about German landscape planning has been published internationally. The literature creates a rather homogenous picture about what landscape planning is and should be. The recent broad agreement contrasts with the controversial discussions about landscape planning during the decades from 1970 until about 2005, when most of the methodological and legal basis of today’s landscape planning was developed.

2. DEVELOPMENT OF GERMAN LANDSCAPE PLANNING OVER MORE THAN ONE HUNDRED YEARS

Landscape planning in Germany has a long tradition that can be tracked back to the 18th century. The scattered beginnings of a planned development of whole landscapes can be dated back to the creation of the “Dessau Wörlitzer Gartenreich” which covers 142 km² (Mittelelbe, 2018). Here, inspired by English landscape parks, the sovereign Leopold III Friedrich Franz von Anhalt-Dessau designed a whole landscape, mainly according to aesthetical principles. Nevertheless, he included models of land uses in order to create an ideal landscape also for the education of his subjects (Kulturstiftung Dessau-Wörlitz, 2005; Küster & Hoppe, 2010). The meaning of the term landscape stemmed from the medieval word “lantscaft” (region) (Tress & Tress, 2001) and was supposedly first scientifically defined by Alexander von Humboldt, opening a pathway for a multifunctional view of the landscape. To Humboldt, a landscape definition explains a landscape in a holistic way as the “total character of a region of the earth” (Neef & Neef, 1977). In the 19th century the idea of the Gartenreich was developed further by the concept of “Landesverschönerung” (“beautification” of the land or land improvement, see: (Wörlitz-Information. (n.d.), 2018) which integrated the ideas of garden art and landscape parks with “Landeskultur” (land cultivation). This stemmed from rational enlightenment, which put forward agrarian, hygienic and social tendencies (K Runge, 1998).

Landesverschönerung had an initially unexpected economic effect, which soon became a purposely used design principle (Pröbstl, 1992).

(5)

By the end of 19th century Ernst Rudorff was the first to use the term

“Naturschutz” (nature conservation) for a rather broad conservation idea, aimed at protecting nature from civilization (see Figure 1). Naturschutz later became the first approach for protecting the environment and landscape planning was to become the instrument for specifying and implementing its objectives (Kraft & Wurzel, 1997). In 1902 the first law was coined for Prussia with the goal to prevent further degeneration of areas with excellent landscapes (Preußisches “Gesetz gegen die Verunstaltung landschaftlich hervorragender Gegenden”).

Figure 1. The total economic exploitation of nature is criticized in the beginning of the 20th century. On the lady’s shield “right of the people” is written, the man’s poster says, “total

economic exploitation” (Wißmann, Jürging, & Schmida, 1999)

Only ten years later, Robert Schmidt demanded in his dissertation for the implementation of spatial planning in a general settlement plan for the Ruhr region, at the time the most polluted area in Germany, and included landscape aspects and green spaces in his plan (K Runge, 1998). From 1920 onwards, the Ruhrsiedlungsverband bought land based on such planning

(6)

designations for green spaces and made the shores of lakes and rivers accessible for public use.

During the time of National Socialism (Nazi regime), planning was integrated into nature conservation and land care/management (“Landespflege”) in the first nature conservation law for Germany, the

“Reichsnaturschutzgesetz”. Lawyers for the landscape (“Landschaftsanwälte”) planned for the greening of the first motorways (Autobahnen) (Karsten Runge, 1990). During the Second World War, the first “landscape planners” became guilty of taking part in planning the colonization of the conquered territories in the East (territory of Poland, Baltic States, Russia, and others). The first professor for garden and landscape design in Germany, Heinrich Wiepking-Jürgensmann, from the Friedrich-Wilhelms-Universität in Berlin, was responsible for the national socialist landscape design in the “German East Territory”. He took part in planning the displacement (and extermination) of the native population, planning new settlement areas for German settlers, features for improving the land and making the landscape suitable for defense by natural barrages such as hedgerows (Gröning & Wolschke-Bulmahn, 1987; Wiepking- Jürgensmann, 1942).

After the war, the socialistic German Democratic Republic (GDR) (1945–1990) acted quickly in exchanging the Reichsnaturschutzgesetz with a new nature conservation act, which concentrated on the protection of species and habitats. Landscape planning was not part of this law because it was not considered necessary. Territorial planning was supposed to include all interests of the society including any green space or environmental considerations. This was logical, as decisions made in the interest of the people (working class) would always find the best (economic) solutions and, therefore, public discussion and consideration of diverging interests were not needed (C Von Haaren & Horlitz, 1993). Environmentalists outside of the state system were thus observed by the State security (Lingenhöhl, 2010). Nevertheless, in the context of territorial planning, geographers developed methodologies for the economic appraisal of the natural capital in order to inform territorial planning about whatwould nowadays be called ecosystem services (Hampicke et al., 1991; Liedtke, 1984; Marks, 1979;

Neef, 1966; UBA., 1986).

In contrast to the GDR, in the Federal Republic of Germany (Western Germany), the Reichsnaturschutzgesetz was still in effect until the new Federal Nature Conservation Act (“Bundesnaturschutzgesetz”) was issued in 1976. Prior to this, some federal states had already reformed their nature state conservation legislation and established mandatory landscape planning.

An example is the state of North Rhine-Westphalia, where landscape planning had been introduced as a legally binding plan for areas outside of existing settlements. This progressive act may be explained by the fact that environmental problems were evident much earlier in the industrialized regions of the Ruhr, where – as mentioned above – spatial planning had been introduced prior to other more rural federal states. This asynchronous development in different German states, in combination with the decentralized situation in Germany, where the young German constitution had assigned almost full responsibility for nature conservation to the federal states, lead to a considerable legal fragmentation in nature conservation and its instrument, landscape planning (Karsten Runge, 1990).

The newly awakened environmental consciousness in the German population and politics in the 1970s, not only lead to the new nature conservation law, but also to the formation of the green party at the end of

(7)

1970s and the inclusion of diverse environmental issues into the program of nature conservation NGOs. This societal atmosphere and pressure paved the way for comprehensive landscape planning, which did not concentrate on species, habitats and landscape aesthetics, but also included the problems of soil, water, air pollution and local climate caused by increasingly intensified land uses and urbanization. Besides the 1960’s legislation that had established thresholds for air and water pollution (Federal Control of Pollution Act, Federal Water Act), no other integrative planning existed for bringing together different spatial environmental issues and integrating these perspectives into administrative decision-making. Thus, landscape planning acted in a double function as sectoral planning for nature conservation on the one hand and cross cutting overall environmental planning on the other hand. In this function, it was the basis for including spatial environmental issues into spatial planning and sectoral land use planning such as agricultural plans, water plans and housing plans.

Since the end of the 1970s, a methodology has been developed for assessing the potential of natural areas (Naturraumpotentiale, later called landscape functions (Langer, von Haaren, & Hoppenstedt, 1985; C von Haaren, 2004) to fulfil the broad objectives of the Nature Conservation Act.

For this, landscape scientists from the West drew on the work of the theories of East German geography for territorial planning (Liedtke, 1984; Marks, 1979; Neef, 1966). The classification of landscape functions was adapted to the tasks of public landscape planning in the West (Bierhals, 1978).

Furthermore, respective mapping and assessment methods were developed for spatially specifying the functions of the landscape for production (soil fertility), recharge of drinking water resources, flood retention, bioclimatic regulation, habitats and species, as well as landscape aesthetics and recreation. The methods were designed for practical application by any landscape planner. Also, the data situation in practice was considered. This major progress was achieved with the help of scientists from different disciplines such as climate and soil science and geohydrology. Economic valuation methods were developed and tested (Bechmann, 1977; Vester, 1984), but discarded soon because of protests from NGOs as well as the scientific community. In some states and especially in big cities like Berlin, typologies and mapping instructions were concurrently developed for mapping and assessing habitats (biotopes) and – later – species (for early Berlin, Herbert Sukopp & Weiler (1988), and H Sukopp et al. (1984). This was, however not well synchronized or coordinated among the federal states, resulting in different classifications and evaluation standards for all German states, a burden, which still nowadays is hindering national German-wide planning, assessments and monitoring.

Already by the 1990s, in the academic planning community, critique was voiced claiming that landscape planning was too schematic, top down, did not include public participation well enough (Hübler, 1997), and was ineffective because it did not change the driving forces of unsustainable development. Therefore, the German Advisory Board on the Environment demanded to further strengthen landscape planning and to develop it into an integrative Environmental Master Planning (“Umweltleitplanung”) (für Umweltfragen, 1998), which would bundle all environmental planning approaches. However, this idea never produced any extensive legal reform.

On the contrary, the growing influence of the EU on German environmental law produced a stronger sectoral fragmentation in environmental conservation and planning. In spite of that, landscape planning proved very effective especially in its informative and precautionary function for urban

(8)

planning and spatial, regional planning (Gruehn & Kenneweg, 2001;

Reinke, 2002; W Wende & Walz, 2017). One reason for that was that landscape planning, after a phase of very complex methodological exercises, concentrated more on the addressees of planning. For spatial and urban land use planning, “translation maps” were processed, which translated the ecological content of the landscape plan into the official designations used by the targeted legally binding planning and implementation instruments (Figure 2)

Figure 2. Map translating objectives of the landscape master plan of the county of Harburg into area designations used by regional planning (modified plans from: Harburg, 2013))

Furthermore, great care was taken to better include the public, stakeholders like farmers, and NGOs into the planning process (Luz, 1994).

Participatory GIS systems, visualization, and mapping exercises by citizens in interactive landscape plans emerged. The aim was to support transparency, public participation and implementation especially on the local scale (e.g. the interactive landscape plan Königslutter, see: C Von Haaren et al., (2005)). This proved a successful strategy, in particular, the function of landscape planning as an accessible information system worked

(9)

well (for an evaluation of the interactive landscape plan, see: Krätzig &

Warren-Kretzschmar, 2014)). The landscape program for Berlin for instance, in combination with the environmental atlas, is freely accessible and the GIS information can be downloaded for use by environmental planners or NGOs. An example from a rural area is the landscape plan for the county of Verden, which has been accessible since 2009 and used about 100,000 times in EIAs, land use planning of local communities, or plans according to the intervention regulation (Verden, 2018).

Looking at recent comments and literature about landscape planning in Germany, there seems to be great consensus that landscape planning should be further developed as a procedural and adaptive plan, which addresses uncertainties and environmental challenges that have been neglected in the past. One of these issues is the energy transition. The expansion of renewable energies is moving into the focus of spatial and environmental planning. The task of landscape planning as a regulating and intermediary instrument, would therefore be to support, among other things, the nature- compatible choice of locations for wind or solar power plants, for grids and storage and simultaneously to protect those areas that are of particular value for nature conservation and landscape aesthetics (see e.g: Marschall, (2018);

Palmas, Siewert, & Von Haaren, (2015); Riedel et al., 2016)). Thus, energy transition is an example for the demand on landscape planning to address the implementation of national objectives. Another example is the German National Strategy on Biodiversity (BMUB., 2015), which was developed for implementing the UN Convention on Biological Diversity (CBD).

Landscape planning plays a decisive role in the bundling and spatial implementation of national objectives, such as increasing the retention areas of rivers by at least 10 % by 2020 (see e.g: BfN (2012); Herberg (2018);

Hoppenstedt & Hage (2017)).

In general, climate protection and adaptation constitute new challenges for landscape planning. They generate further topics of focus, such as tackling changed habitat conditions for animal and plant species as well as new mitigating measures, e.g. the development of sinks for greenhouse gases. Recent research reveals that an integrative approach in landscape and environmental planning, which uses multifunctional conservation measures, can be more effective and efficient than sectoral strategies (Galler, von Haaren, & Albert, 2013). The advantages of multifunctional measures can be analyzed and quantified in landscape planning in terms of spatial and monetary efficiency (ibid.). Implementation of such measures are already now demanded by other instruments like the Strategic Environmental Assessment (SEA) or the EU Water Framework Direction (WFD).

Additionally, considering the increasingly dynamic landscape changes, a more flexible, process-oriented and modular approach to landscape planning is required. This would, on the one hand, lead to a more focused management approach, and on the other hand, to fast, adaptive solutions, which can deal better with uncertainties. In addition, a modular planning process enables landscape planning to set specific priorities according to spatially specific problems (see e.g: BfN (2012); Heiland (2010);

Hoppenstedt & Hage (2017); Neuendorf, von Haaren, & Albert (2018)).

Furthermore, the application possibilities of the concept of ecosystem services are currently in discussion. Although landscape planning already maps and evaluates landscape functions, ecosystem services could deliver an additional communicative benefit by including an economic perspective.

This could promote advantages in the communication with decision makers.

(10)

However, suitable data for economic analysis and assessment are still scarce (see e.g: Albert, von Haaren, & Galler (2012); TEEB (2011)).

3. OVERVIEW OF CURRENT LANDSCAPE PLANNING LEGISLATION AND STATUS OF LOCAL PLANNING

The objectives, tasks and content of landscape planning are legally defined in the Federal Nature Conservation Act (BNatSchG., 2010). Table 1 provides an overview of the most important German legal requirements concerning landscape planning.

other planning and administrative procedures must make allowance for the content of landscape planning. Where a decision does not make allowance for the contents of landscape planning, justification must be given (Art. 9 par. 5 BNatSchG). This applies for instance to regional planning, zoning or local land use planning. Representations or designations of the landscape plan should be included, a regulation which is reflected also in the Federal Building Code.

The general task of German landscape planning is a precautionary planning which spatially specifies the general objectives of nature conservation and landscape management and which develops measures to achieve these objectives (Art. 8 BNatSchG). The justification for the protection of nature and landscape refers to the intrinsic value of nature, but also to nature as the present and future basis for life and human health (Art.

1 par. 1 BNatSchG). In Germany, three basic goals (basic values) are defined by law which refer to biodiversity, natural resources and landscape aesthetics and recreation. These basic values form the basis for the spatial assessment of landscape functions/ecosystem services and development of objectives in landscape planning. Thus, landscape planning pursues an ecosystem-based, cross-sectoral planning approach in which all natural assets are considered, also in their interaction (BfN., 2012). Along with these basic goals and values, the content of landscape plans is legally defined (see Table 1 and Art. 8ff BNatSchG).

According to the federal law, landscape planning is mandatory on the supra-local political-administrative level with no exceptions (as a rule on the regional level; instead, exclusive planning on the state level is possible only if worked out in content and degree of specification equivalent to the regional level). On the local level, it has to be performed in case of environmental problems and changes of nature and landscape. This flexibility was considered necessary because some German states are very small and cover just one big city. A four-level planning system is possible and common in the larger states (see Figure 3). Each level should take into account the planning of the higher level, but only represent what it can plan according to its own responsibility.

(12)

Figure 3. Landscape planning on the different planning levels in Germany

A principle of assigning the different tasks of landscape planning to the different planning levels should be that the respective level is able to overlook the respective ecological problem and take responsibility for solving it (according to the principle of subsidiarity). This applies as well to the spatial dimension of a problem such as the value dimension. For example, if a river catchment spreads over different regional administrations the next higher, supra-regional political entity should conduct the planning – in Germany the state or national level. Natural assets of high national, EU or global value (such as many endangered species) should be handled on the international and national levels. Unfortunately, in Germany, the extensive competencies of the federal states often disrupt this principle of sharing labour. National parks are designated on the state level, and some federal states (such as Lower Saxony) have downscaled competencies in nature conservation to the local level. This causes, for example, inefficient administrative procedures because several counties have to coordinate the designation of one protected area. In consequence, international obligations for climate or biodiversity protection are fulfilled late or not at all. A task of landscape planning would not only be to downscale such obligations to the different decision levels, but also to demonstrate which responsibilities should be taken by which administrative level.

The different levels of landscape planning are well equipped to undertake these tasks: Landscape programmes display targets and guidelines for the federal states. The spatial content is depicted in maps on a spatial scale from 1:500,000 to 1:20,000. The maps display priorities and coordinate targets such as statewide habitat networks or large protected areas (BfN, 2012). Regional landscape master plans specify the state’s programmes for the regional level on a scale from 1:100,000 to 1:25,000 and add regionally relevant information plus objectives. These refer, for example, to regionally endangered habitats, regional habitat networks, as well as areas that should be protected because of their high soil fertility or because of their importance for storm water retention (BfN, 2012). Local

(13)

landscape plans are worked out for the area of a municipality. They provide planning on a scale from 1:10,000 to 1:5,000 as they spatially specify the general objectives of nature conservation and landscape management.

Landscape plans also serve as a source of information for the overall spatial (territorial) planning, especially for regional planning. This iterative interplay of information between the planning levels is called the “counter current” principle. Additionally, mandatory open space structure plans on a scale of 1:2,500 to 1:1,000 can be drawn up for parts of municipalities for a detailed assessment and design of nature and landscape, e.g. in areas of new housing development or recreation (BfN, 2012).

According to the legal obligation to plan, but also because states, regions and municipalities considered it useful to have comprehensive environmental information and management guidance, landscape planning has been performed almost everywhere in Germany. Figure 4 shows that many counties are already in the second or third phase of up-dating their regional landscape plan. On the local level, an empirical study from (Stein, Wende, & Walz, 2014) revealed that 72.5 % of the German municipalities have drawn up landscape plans. But in fact, this numbers differs between the federal states. Peripheral, agrarian municipalities are less interested in working out a local landscape plan. For example, in Rhineland-Palatinate 98% of the local authorities have a landscape plan, whereas in Mecklenburg-Western Pomerania only 15% of the (much smaller) municipalities have one. Public access via the internet does not seem to be very advanced on the local level. Only 32 landscape plans, which are digitally accessible, have been identified (BfN, 2018b)

Landscape planning is established by law not only as a conceptual but also as an integrative instrument into other planning or sectoral decision making. As stated prior, the Federal Nature Conservation Act explicitly emphasizes that in the preparation of landscape plans the applicability for regional and local land use plans, as well as for other planning and administrative procedures, is to be considered. For example, the content of landscape planning can serve also as an information basis for the EIA or intervention regulation and provides environmental objectives for these purposes (§ 9 par. 3 and 5 BNatSchG (BfN., 2012). Landscape planning also provides information about the use of environmental related subsidies (§ 9 par. 3, no. 4c BNatSchG). The main legal pressure for other sectoral planning to include or observe the content of landscape planning comes

(15)

from an obligation for explicit statement of grounds in case of non- compliance to landscape planning objectives (see Table 1 and Art. 9 par. 5 BNatSchG). However, whether this obligation is implemented in practice by local or sectoral authorities depends largely on control of planning and approval procedures by either superordinate authorities or by a vigilant public, which has access to respective approval documents. In order to support the control function of the public in some states, environmental NGOs are financially supported by the state (Zschiesche, 2015). However, support has proven often unreliable and depends very much on the political orientation of the respective state government (ibid.).

4. GOVERNANCE CONTEXT FOR LANDSCAPE PLANNING IN GERMANY

4.1 Typology of framework conditions for landscape planning in Germany

Planning instruments are not developed in a societal vacuum or as stand- alone solutions. Therefore, in order to draw conclusions from the German example, as well as for improving landscape planning in Germany, its framework conditions should be understood. Several factors are important for the tasks assigned to landscape planning in the Nature Conservation Act, for implementation of landscape planning objectives, for use as an information base, and for how the ecosystem services are used and assessed in landscape planning. The most important of these factors seem to be: (i) the degree of legalization (predefinition of environmental decisions by legal standards), and in that context the role and legal opportunities as well as practice of public participation (including access to environmental information); (ii) the legal status of property rights in a country, and (iii) the power on different political decision levels to make these decisions (centralized versus localized power or tiered system) (Shandas, von Haaren et al., forthcoming).

According to these factors German landscape planning is influenced by - property rights tamed by social obligations, which pave the way for an

acceptability for public, planned influence on land use,

- public participation which often supports the objectives of landscape planning but is also restrained by a strong legalization of environmental protection, and

- an imbalance in favour of local power and competencies in land use decisions (see Figure 5).

- In Figure 5, Germany is characterized on the one hand by a rather strong and specific environmental legislation, which frames public participation. On the other hand, extensive though not sufficient public participation rights exist and influence the function of landscape planning as an environmental information system. In principle, private property is protected but land use rights are limited by obligations to the society. This improves chances for implementation of public planning compared to a situation with very strong property rights. The planning system is tiered, but with an emphasis on the local level, thus impeding the implementation of certain supra-local environmental objectives. In the following section, this simplistic characterization will be substantiated.

4.2 Degree of legalization/participation in Germany

In Germany, legal standards for evaluation of environmental values as well as impacts are well developed. This is particularly because a lot of such standards, or the obligation to define them, have been issued from the EU in the past decades. Examples include the lists of species with different degrees of endangerment and/or protection (according to the habitat directive and German nature conservation law), the assignment of different values to habitat types, the standards for the quality of water bodies predefined by the Water Framework Directive and related documents, standards for air quality, and thresholds for pollution, etc. These standards become effective in decisions because either the weighting of different land use interests cannot overcome them, or, at the least, the standards have to be explicitly considered. If decisions are more or less predefined by the demand to comply with a standard, then not only the leeway for political decision is limited, but also the scope of public participation. Therefore, public participation is constrained or even excluded for example in cases of designation and management of nature conservation sites, protected species, or the decision of whether noise thresholds have to be observed. In the evaluation of landscape functions/ecosystem services, in addition to a legally based evaluation, a citizen-based evaluation can be added, but is not required. Due to the dominance of the legal perspective, as well as to the definition of the tasks of landscape planning for the conservation of public, and less for private market interests, only few economic valuations with practical importance exist. It is presumed that the interest of NGOs, stakeholders and other citizens will be expressed in participation processes.

These are prescribed by law in almost every approval process, in EIAs and spatial planning, but not for landscape planning. The reason is probably that its objectives and measures, as said before, do not become mandatory in most federal states. Nevertheless, landscape planning also prepares legally binding decisions, with relevance to use of property rights, such as the designation of protected areas. In practice, public participation is part of planning processes in almost every landscape plan on the local or regional

(17)

scale. The influence of participation on land use related decisions is on the one hand limited because of the mentioned predefinition by legal standards.

On the other hand, participation is often practiced extensively, and NGOs and citizens have, in many cases, the right to sue if environmental standards are neglected in project planning (Umweltrechtsbehelfsgesetz (§ 2 UmwRG), Umweltschadensgesetz (§ 11 USchadG)). The rights of NGOs and the public have been strengthened in Germany, mainly by efforts for implementing the Aarhus Convention. Landscape planning can contribute considerably to providing the environmental information needed for enabling citizens and NGOs to take an active part in public participation. In general, the preventive effect of the opportunity to control and possibly to revise official decisions, may be even more effective for making politicians and administration comply with environmental rules than the actual exercise of the right of appeal in court cases. However, the Aarhus Convention has not been implemented completely in Germany. Firstly, in practice, unlimited access to environmental information cannot be taken for granted because a lot of information, especially GIS shape files, is proprietary. Secondly, the unrestrained right of any public to participate and to sue if the petitioner is not personally affected is still missing. This weakens the public control over political decisions, especially on the local level, and thus also the obligation for any public decision makers to explicitly give reasons if deviating from the recommendations of the landscape plan (according to § 9 par. 5 BNatSchG).

4.3 Extent of private property rights

Most land in Germany is private. However, legally protected property rights can be curtailed if public interests demand this. Additionally, land use rights, such as the right to build or the right to extract ground water, are granted by the state and are not part of owning a piece of land. This is an important asset for land use planning (including landscape planning) as it is possible to shape land uses to a limited extent according to public demands.

For example, zoning is possible without compensating land users for not allowing them to build on their ground. In return, spatial planning has to strive for a high degree of legitimization in land use designations and thus in the underlying evaluations, because they may have serious consequences for property rights of land owners if implemented.

4.4 Degree of centralization of decision and planning system

As previously stated, landscape planning in Germany is mandatory at certain political levels. At the federal states or regional level, landscape planning is mandatory and has to be performed by the municipalities if the environmental situation demands a planned solution (see Section 3). This situation mirrors the weakness of the national level in all issues of nature conservation and thus also the gap between the European level and the implementation on the local level. For instance, national parks or the network Natura 2000 are not protected by the national government but by federal states. The autonomy of the communal level in many decisions, which may have impact on broader scales, creates some problems of spatial fit. Examples are land consumption, measures for climate mitigation, in some federal states even protection of habitats of national importance,

(18)

which have to be designed and implemented on the local level (Albert et al., 2016, Albert et al., 2017). This affects landscape planning in many ways.

Designation of supra-locally important areas are much more difficult when there is no well tiered distribution of competencies. Affected land users at the local level often have direct access to local politics and local administration is often not well equipped in terms of human resources for withstanding pressure of lobbies in conflicts.

5. DISCUSSION AND CONCLUSION

Landscape planning in Germany has a long tradition and a comprehensive and effective legal base in the Federal Nature Conservation Act. Methodologies for evaluating landscape functions and deducing responses are well developed. Economic approaches do not yet play an important role, due to a strong legal base of evaluation and planning.

However, economic approaches have recently been considered as a means of communicating to politicians. Consequently, land use designations in landscape planning have a high degree of legitimization; they can be based on more or less specified legal objectives and standards in environmental legislation. Implementation options are designations of protected areas, integration into mandatory spatial planning, local land use planning and zoning or sector planning such as water management plans. Furthermore, landscape plans should be taken as a basis for targeting public funding for environmental services. An important function of landscape plans is that of a consolidated environmental information system, thus empowering citizens in public participation, and supporting screening and scoping in the before mentioned planning processes, environmental impact assessments 1 and the intervention regulation. Digitalization as well as web-based landscape planning is supporting participation, information update and flexible planning. Excesses urban development occurring in countries without spatial planning and regulation (Dixon-Gough, 2015) could thus be prevented.

Areas with qualified landscape plans show a much better integration of environmental considerations into land use planning than unplanned areas.

The example of the Green Belt Berlin along the former Berlin Wall is an excellent example for what such planning might achieve (Kowarik, 2019).

This is the case even when the landscape planning designations are not legally binding, because environmental impacts become public and proposed measures may become mandatory.

However, the information which landscape planning provides is often not welcomed by landowners and users. Thus, landscape planning is not undisputed and political support weak. Furthermore, some serious barriers impede the effectiveness of landscape planning in Germany: strong driving forces like market forces leading to the intensification of agriculture, or land consumption by urbanization, cannot be halted by landscape planning alone.

Binding payments for ecosystem services such as the agri-environmental measures of the EU to target areas designated by landscape planning (as practiced in North Rhine-Westphalia) would be an important measure to improve the environmental situation in agricultural landscapes. Furthermore, the effectiveness of landscape planning could be probably much enhanced by improving the right to sue for citizens, providing better access to the information of the landscape plans for citizens and NGOs, and through a homogenization of classifications and evaluations of landscape functions/ecosystem services across the federal states. A more balanced and

(19)

adequate distribution of competencies between the different political levels would hopefully reduce some of the burden which land user resistance creates in implementation processes on the local or county level.

To conclude, the analysis of German landscape planning demonstrates on the one hand that a planning system can be designed effectively and consistently in one legislative act. On the other hand, the methodologies applied, and notably implementation options and their effectiveness, are influenced strongly by national framework conditions. This refers in particular to the role of property rights, legalization, participation and centralization. Beside public opinion and political will, these factors influence how evaluation is performed (Shandas et al., 2019) and, more importantly, whether strong environmentally harmful driving forces can be controlled.
