Abstract
There are many economic aspects associated with landscape. Firstly, landscape is an “externality”, as the economic activities involving the use and transformation of landscape have different effects and repercussions on the same; secondly, landscape, especially in modern society, is seen more and more as a limited resource, and is therefore perceived as an “economic good”. In consideration of these assumptions, the current chapter will examine the main indicators used in literature to assess the economic aspects of landscape, with an interpretation on the basis of two major approaches to analysis: the “economic value” of landscape and the “economic strength” of landscape. Finally we will propose a set of indicators based on the DPSIR model on two different scales for monitoring macro transformations (regional scale) and the following in-depth study (local scale).

8.1 Principles and Definitions
There are many economic aspects associated with landscape. The economic activities related to the use and transformation of landscape have various effects and repercussions on the same; according to the literature in the field of economic analysis this is tantamount to saying that landscape is a (positive or negative) externality (Marangon and Tempesta 2008). In general terms, externalities are defined on the basis of the effects (favourable or unfavourable) on the production or consumption of one person by the production or consumption of another, without there being any kind of monetary transaction between the two to balance the costs or benefits of these effects.
Furthermore, landscape, especially in modern society, is seen all the more as a limited resource. From the point of view of economic analysis, this is the same as saying that landscape can be considered an “economic good”, in other words a good available in an insufficient quantity to meet requirements for the same, and for which there is a problem of efficient allocation of resources, guaranteed or not as the case may be by the spontaneous actions of the market (Santos 1998).
In consideration of said characterization, the use of evaluation tools to estimate the value of landscape can be explained on the basis of two main themes. First and foremost we must have tools to establish and assess the foreseeable benefits of certain actions involving the use and transformation of landscape. Secondly, techniques must be established for the assessment of the effectiveness and efficiency of public expenditure for interventions on landscape.Therefore landscape assessment can be translated into economic indicators used to draw up policies for the protection and requalification of landscape.
Indicators have only recently been used in the assessment of the economic aspects of landscape, and are still subject to development. Available publications on the subject indicate two main approaches in the study of economic landscape indicators . The first, more experimental approach, refers to the so-called “economic value” of landscape (Marangon and Tempesta 2008; Marone 2007). According to this approach, the value of landscape is generally established by the so-called existence value, theoretically unrelated to the benefit each person could obtain from a resource, substantially a value closely associated with the many functions it may have for man. In this perspective, landscape has a historical, cultural, recreational, panoramic and aesthetic value; it represents a value for the spirit, for its contribution to biodiversity and ecosystems, security and stability, the production of goods, and employment (Reho 2007).
These aspects/functions of landscape refer to various parties with a vested interest: for farmers (in the case of farmland) and rural communities it is a place to live and work; for society it is a recreational place; but landscape also provides specific environmental services associated with maintaining biodiversity and ecosystems, etc., of interest for generations both present and future.
With the first approach, there are two types of landscape demands (and components of the value).The first demand derives from the tendency of people to try and pass part of their time in more pleasant or more interesting environments from an aesthetic and perceptive point of view. Therefore, the quality of landscape influences the real estate market and recreational behaviour, while a second type of landscape demand is related to the need to protect cultural heritage in its various forms.
A second, more consolidated, approach, that has been called “economic strenght ” (Nordregio 2000), establishes a connection between the value of landscape and the contribution of the same to the economic system of reference. Therefore, this involves assessing landscape on the basis of the effects that utilization and transformation have on the economic system. These effects are connected, for example, with an increase in tourist flow deriving from the implementation of policies for landscape development of a site or job losses in the agricultural sector as a result of financial measures implemented to support agricultural production of specific value for landscape.
8.2 A Review of Economic Landscape Indicators
The search for specific indicators able to represent the economic aspects of landscape is used in a recent and quite expertimental literature.
The OECD (2001b), as part of its activities associated with the assessment of agricultural policies, lists a series of indicators for landscape assessment, including also some indicators based on economic value.
These indicators were used and studied in depth in a recent Italian study (Marangon and Tempesta 2008), with a precise classification of economic indicators, applicable assessment techniques, and references to specific studies of the past.
In particular, in the authors’ opinion, the value of landscape is attributable to the benefits produced by the same. In this sense, the categories of benefits that landscape can produce are associated with the following aspects:
-
1.
Benefits from direct non-extractive use, in other words when a person uses an area with an attractive landscape for recreational purposes. To establish this value, the importance of landscape essentially depends on the type of recreational activity;
-
2.
Benefits from indirect use associated with owning a home in a certain area with an attractive landscape;
-
3.
Benefits from the non-use of the landscape due to the conservation of historical-cultural heritage.
We must emphasise that the use of these indicators is dictated by the availability of very specific data and information, which can only be obtained through direct interviews and surveys examining the benefits produced by landscape from the point of view of potential users (inhabitants or tourists for example). With this approach, the indicators relevant to the value of landscape can substantially be divided into monetary and non-monetary indicators.
For non-monetary indicators, according to Marangon and Tempesta (2008), the result in quantitative or qualitative terms depends on the criteria used in the various fields of interest (with reference to diversity, connectivity, etc. from an ecological point of view, visual quality, complexity, coherence, mystery, etc. from a perceptive point of view, etc.).
There are many publications on the question, from a variety of disciplines. The methods of assessment to which these criteria refer are divided into objective methods (indirect, historical for example) and subjective methods (direct, visual perception for example) by convention. The first are based on the opinions of experts in the assessment of material and formal aspects; the second are based on the level of satisfaction of the community of users in relation to the more intangible aspects of landscape (the identity, symbolic and cultural value, …). The use of these indicators lets us attribute a value to landscape to draw up policies, and comprehend the level of satisfaction in landscape and transformations by society (Tempesta 2006).
As for monetary indicators however, there are some methods that can provide an economic assessment of value for landscape (Stellin and Rosato 1998). These methods can be divided into two major categories, depending on whether they are based on the costs to bear for producing and maintaining the asset, or on the demand of the same asset.
Therefore, we have:
-
Methods based on supply analysis (costs)
-
Methods based on demand (benefits)
In other words, the monetary value of landscape refers to two main categories of indicators relevant to:
-
the cost to maintain and develop certain landscapes;
-
the willingness to pay to use a certain landscape, or accept compensation for not using the same.
The analyses of the cost/opportunities for alternative landscape and cultivation assets and the quantification of the costs necessary for the conservation of landscape (defensive expenditures) belong to the first group. The assessment of the benefits produced by the landscape, which can be calculated using methods based on the stated preferences (the willingness to pay to keep a certain landscape intact for example) or on revealed preferences (travel costs to use a certain landscape for example) belong to the second.
Table 8.1 contains a classification of the indicators available for the assessment of the economic value of landscape.
Despite the many difficulties involved in the application of calculations for the proposed indicators (monetary in particular), the same certainly provide a major contribution in assessing demand and supply for the landscape good. The use of these indicators can therefore be a useful support in the development of landscape policies, providing information on the importance attributed to the same by the local population, and also a trade-off between costs and benefits associated with the management of a certain landscape.
The approach used to establish landscape value based on the contribution of said landscape to the economic system of which it is part (“economic strenght ”) refers to more consolidated publications on the theme of assessment of the economic structure and performance for a certain area (Eser 1999; Nordregio 2000).
With this approach the indicators are used for the assessment of agro-environmental policies and refer to interscalar type applications ranging from a national level (assessment of economic performance in the agro-environmental sector of the various member states of the European Union) to a local level (assessment of the effects of financial measures to support single rural enterprises).
It must be said that, unlike the first approach, this approach does not explicitly refer to the theme of landscape, but rather to a series of policies and actions in the territory which envisage, amongst other things, also interventions for the protection and reclamation of landscape.
This approach is usually followed in Rural Development Programmes promoted by the European Union where the aim is to assess and test the effectiveness of public expenditure to reach planned goals.
The main references to this approach are the indicators of the PAIS project—Proposal on Agri-Environmental Indicators (Landsis et al. 2002) and the CMEF model (Common Monitoring Evaluation Framework), recently implemented by the European Commission (2006) to assess Rural Development Programmes.
In particular, the PAIS project proposes a set of economic type indicators to apply in the assessment of rural development at a European level. These are descriptive social-economic indicators concerning the quality of life; economic structure and performance; population and migration (Table 8.3).
In the CMEF model however, there are a series of indicators that provide a quantitative figure on the contribution of landscape policies (agricultural policies in this case) for the overall economic requalification of the area in question.
The studies on indicators for the sustainable development of the agricultural sector (Wascher 2000; Waarts 2005; EEA 2005; MTT 2002; Van Heuckelom 2004), the cattle-farming sector (Wright et al. 1999) and the forestry sector (MCPFE 1998) also refer to this approach.
Finally, there are a series of studies on landscape assessment through multicriteria analysis, in which economic indicators are used with others for global landscape assessment (Gómez et al. 2003).
8.2.2 Catalogue of Indicators
Below you will find a list of the main economic indicators used for the assessment of landscape in current publications, on the basis of the two approaches described above. The indicators have been organized in brief categories on the basis of the subject (Table 8.4).
8.3 Proposal for Economic Landscape Indicators
On the basis of the published indicators described above we will now propose a selection, which will later be studied in depth from the point of view of application.
For the selection of the indicators we decided to adopt some criteria for establishing the significance of the same, taking for granted that all the published indicators meet essential requirements for environmental indicators (see Sect. 2.1.1 of this report).
The criteria used to select the indicators refer to:
-
Field of application: the criterion is used to measure the level of technical and operational difficulty and to calculate the indicator (holding ad hoc interviews, static elaborations, …), and to interpret the results;
-
Completeness: the criterion indicates whether the indicator considers (from an economic point of view) the various aspects involved in the landscape system in a comprehensive way: not only agricultural structure, but also aspects associated with perception, tourism flows …;
-
Specificity: the criterion establishes whether the indicator is essential or not in the economic characterization of landscape.
When selecting the indicators we chose to favour those characterised by completeness and high specificity; furthermore, we decided to consider indicators that can be used in both approaches.
The selection resulted in the following indicators (Table 8.5).
Note that each of the indicators proposed corresponds to a specific scale of application. The scale is closely linked to the availability of source data for calculating the indicators, in order to obtain a legible result. In this way, two different systems of economic indicators are created: one for monitoring macro transformations (regional and provincial) and the other for studying the analyses in-depth (sub-provincial and local level).
Furthermore, as can be seen in the last column of Table 8.5, the proposed indicators guarantee coverage of all the DPSIR model categories.
8.3.1 Presentation of the Indicators Proposed
Below you will find an in-depth presentation of the indicators proposed (Tables 8.6, 8.9, 8.12, 8.13, 8.16, 8.17, 8.18, and 8.19), on the basis of the presentation table used for the study (Sect. 2.2.2). Where possible, the indicators have specific boxes to illustrate their application. The boxes contain some examples related to real cases where the different indicators have been calculated.
