1. Introduction
The promotion of economic, social, and territorial cohesion has been one of the main pillars on which the construction of the European Union (EU) rests. This general principle has been expressed over the years through the objectives and priorities that have guided the Union’s successive strategic guidelines in each programming period [
1]. Currently, this is still a relevant issue on the current European political agenda, as reflected in its ‘Europe 2020′ growth strategy [
2], which was designed based on the conviction that territorial coordination is a strategic factor on the path to inclusive economic growth [
3].
However, despite the past and present efforts of EU policies to achieve territorial cohesion and the achievements in this regard that have been made in different stages and time contexts [
4,
5,
6,
7,
8], the reality is that European territories suffer from many important territorial imbalances at various scales and of very different types [
9]. The most recent EU enlargement and, above all, the recent financial and economic crisis of 2007–2008 that devastated most European regions and countries, have been identified as the main elements that have contributed to increasing current territorial inequalities [
1,
10,
11]. Indeed, previous research has concluded that periods of economic prosperity stimulate regional convergence dynamics, while situations of crisis or recession lead to divergent territorial processes [
12,
13,
14,
15]. These situations occur between countries, but also between regions and territories belonging to the same country [
16]. The trajectory followed by the region of Andalusia during the economic crisis (with unemployment rates tripling) is a clear example of this, where disparities can be observed not only in comparison with other Spanish and European regions, but also internally between their territories.
In addition to the analysis of inequalities between countries, regions, and territories, some authors point to the need for this type of study in rural areas, taking advantage of the close relationship between European regional policy and rural development policy [
17,
18]. In effect, the rural milieu is diverse, the potential ways of development are multiple, and the disparities between rural–rural territories are a reality [
19]. In the case of Andalusia, previous studies show that there are indeed significant inequalities between the different types of rural territories [
20,
21].
In the rural milieu, these inequalities take many forms that reinforce each other, both from the individual perspective with vertical inequalities, and from the collective perspective with horizontal inequalities [
22]. It is in this second dimension where inequalities between rural territories can be found when these are understood as the result of a social construction.
In this context, it is useful to apply the concept of territorial cohesion because it allows the development of the territory to be geared towards meeting the major challenges it faces [
23]. This is a concept that has been gaining ground in the political agenda of the institutions since its origin within the European Union (EU) in the 1990s. This is mainly reflected through three key elements: (i) The incorporation of the territorial dimension in the Second Cohesion Report [
24]; (ii) the publication of the Green Paper on Territorial Cohesion [
25]; and (iii) the regulatory recognition given to territorial cohesion in the Lisbon Treaty as one of the three fundamental pillars of EU Regional Policy.
Despite the importance that the concept of territorial cohesion has been acquiring within the EU and the progress made in the fields of different scientific disciplines to clarify its meaning, several authors warn of the inaccuracy that still exists in the definition of this concept [
26,
27,
28,
29,
30,
31]. This lack of definition makes it even more difficult to measure the territorial cohesion of a given territory, but it does arouse scientific interest in advancing the design of methodologies that can be used to analyze it and thus provide new knowledge.
Under these circumstances—the context of territorial imbalances, the need to move towards convergence of territories, and the difficulty of measuring a concept with a markedly abstract component—give rise to the need to undertake research capable of addressing the analysis and measurement of territorial cohesion [
32]. Among the few studies that have empirically addressed the measurement of territorial cohesion, apart from those carried out by the European Spatial Planning Observation Network (ESPON program), those conducted at the European level [
1,
33,
34,
35,
36,
37] and in Latin America [
23,
38] stand out.
This is a series of studies in which territorial cohesion is measured in different contexts and at different territorial scales, but which in no case focus on the rural environment. Similarly, although all of the works contemplate the diversity of contexts in which the analyzed territorial units are developed, this has not been sufficiently incorporated in the empirical analysis. This has led to the fact that, on many occasions, very different regions and territories have been contemplated as a homogeneous ‘whole’. For this reason, despite these advances, which undoubtedly represent an important methodological reference, it is of interest to develop studies that consider the analysis of territorial cohesion and the search for factors that affect it through territories with characteristics of homogeneity among themselves, both in their initial conditions and in their level of territorial resources [
21].
Hence, the main objective of this paper is to conduct an analysis of territorial cohesion in rural areas of Andalusia, one of the European regions most affected by the past economic crisis, considering the different contexts in which their territories are developing. Specifically, the purpose is to measure the territorial cohesion of the different rural areas and identify the main factors associated with it. The identification of these specific factors for each type of territory is useful in guiding the design of specific policies that seek a harmonious and balanced development of rural areas.
2. Territorial Cohesion: Progress in the Concept to Articulate Its Measurement
The concept of territorial cohesion emerges explicitly and in detail in the Second Cohesion Report [
24], during Michel Barnier’s mandate as European Commissioner for Regional Policy [
39]. Since then, several works have addressed the analysis of this term, giving rise to a broad debate on its meaning. The main contributions made in this regard include: (i) Those that deepen the evolution of the conceptualization of the term, taking into account its French roots [
40], the evolution of the European model of society [
41], the new forms of governance [
42], the principle of subsidiarity [
43], and its link with sustainable development [
44]; (ii) those that highlight the diversity of paths to define territorial cohesion, giving rise to multiple conceptualizations [
45]; (iii) those that focus on the analysis of policy objectives [
46] and on the establishment of principles and guidelines for effective policy implementation [
47,
48,
49]; and (iv) those that establish a conceptual interpretation and provide a methodology of analysis [
23,
35,
50].
In spite of everything, the scientific literature shows a lack of consensus on the existence of a precise and widely accepted definition of the term ‘territorial cohesion’ and, as a result, from an operational and practical point of view, calls for progress in identifying the main dimensions and elements that make it up [
34,
51]. In order to identify these dimensions, some authors stress the need to first consider the implications of studying the analytical parts of the term ‘territory’ [
52,
53]. Accordingly, in the field of disciplines such as human geography or development economics, territory can be understood as a metric topographic space characterized by three elements or subsystems [
54,
55,
56,
57,
58,
59]: (i) Specific territorial resources available to the territory; (ii) territorial actors or agents (the State, civil society and associations, and private actors); and (iii) institutional arrangements that articulate the processes of transformation and development aimed at solving the common or specific problems faced by territories. The relationship established between these three elements is decisive in the processes of territorial convergence (or divergence) and must therefore be considered in cohesion analyses.
Based on these elements and on those provided in other studies, mainly developed by the European ESPON program [
60,
61,
62], but also by the European Commission [
63,
64,
65] and by researchers in the field of geography and economics [
35,
51], five basic dimensions can be established that provide theoretical support for the design of a methodology to measure territorial cohesion:
Economic dimension: As a fundamental basis for addressing the main challenges facing territories (i.e., the constant increase in global competition) and thus contributing to the ultimate objectives of growth and development [
66,
67,
68,
69].
Social dimension: Founded on the skills and abilities of individuals and their ability to establish relationships with other territorial actors through the formation of social networks. These networks act as a link for the deployment of economic initiatives aimed at ensuring the population’s well-being [
70,
71].
Environmental dimension: Based on the recognition that the environment is the support of life. Therefore, environmental integration must be made effective in development processes, placing this dimension on the same level of value as economic and social issues [
62,
68,
69].
Institutional dimension: Understood as the regulatory framework under which formal and informal agreements are made to guarantee the proper functioning of the system and the development of the other dimensions. Relational capital and governance are key elements in this sphere [
72,
73,
74].
Integrated spatial development dimension: Based on the principles of balanced territorial development aimed at promoting a polycentric territorial structure, both in terms of the morphology of territories and the relationships established between the settlements or municipalities that comprise them [
64,
68].
The identification of these dimensions clarifies the meaning of the concept, but, above all, it enables the most appropriate components to be associated with each dimension in order to measure territorial cohesion accordingly.
Figure 1 shows the analytical model used for this purpose.
4. Results and Discussion
The identification of different territorial contexts for analyzing territorial cohesion made it possible to establish two groups or categories of rural counties with environments that are more or less favorable to the processes of rural development and territorial cohesion (
Figure 4).
Based on the main characteristics of the counties, two groups or types of rural territories can be found:
Type 1 covers remote peripheral areas, generally located in mountainous areas with significant demographic and educational problems. They have a valuable natural heritage and an agricultural and livestock sector with an important weight in the rural economy of the counties. These are the rural areas which, a priori, present the least favorable environments for progressing in their development and territorial cohesion.
Type 2 includes counties with favorable orography and geographical location, in some cases near the main cities of the counties and, in others, with good communication with the main centers of development in the region. They have great demographic potential and, in addition to an important agricultural and agri-food sector, the industrial and service sectors stand out.
The application of the factor analysis performed independently in each of the two types of rural territories for each of the dimensions of territorial cohesion allowed the original 22 indicators to be reduced to a total of 10 factors in each of the types (two for each dimension) (
Table 2). The results of the factor analyses are summarized in
Appendix A (
Table A1 and
Table A2).
A partial territorial cohesion index (PTCI) relating to each dimension was obtained by applying the DEA based on the resulting factors. The GTCI was also obtained by aggregating indices using the DEA.
Table 3 and
Table 4 summarize the results obtained in each analysis for the counties of each type of territory.
The results for the economic dimension (PTCI_Eco) show that three type 1 counties (‘Alpujarra Sierra Nevada Almeriense’, ‘Los Pedroches’, and ‘Gudalteba’) and three type 2 counties (‘Levante Almeriense’, ‘Medio Guadalquivir’, and ‘Estepa Sierra Sur Sevillana’) are the most favorable or efficient (with indices equal to one hundred). In the case of the type 1 counties, ‘Alpujarra Sierra Nevada de Almería’ stands out from the rest due to factors such as innovation and the level of entrepreneurship, which has earned it recognition in past editions by the Andalusian Center for Entrepreneurship. ‘Guadalteba’ and, above all, ‘Los Pedroches’ stand out for the dynamism and diversification of their economies, closely linked to the agricultural and livestock sector. In the type 2 counties, ‘Levante Almeriense’ stands out mainly for its economic dynamism, closely linked to horticulture and the agri-food sector and its high level of employment; the ‘Medio Guadalquivir’ county for the levels of investment in the creation of new industries; and ‘Estepa Sierra Sur’ for the diversification of its economy and the high levels of economic growth experienced in recent years.
The results obtained for the social dimension partial indices (PTCI_Soc) show that, in type 1, there are two counties that show the most favorable situation (‘Los Vélez’ and ‘Guadajoz y Campiña Este’), and there are four counties that can be observed in type 2 (‘Campiña de Jerez’, ‘Vega Sierra Elvira’, ‘Condado de Huelva’, and ‘Costa Occidental de Huelva’). In the case of the type 1 counties, ‘Los Vélez’ stands out from the rest because of the equitable distribution of income among the municipalities that make up the county, and ‘Guadajoz and Campiña’ Este because of the high rates of representation of women in decision-making positions. In the case of type 2 regions, ‘Campiña de Jerez’ stands out for its high levels of decentralization of income and territorial equity, ‘Vega Sierra Elvira’ for the high levels of training of the population, ‘Condado de Huelva’ for cooperative promotion, and ‘Costa Occidental de Huelva’ for inclusion and gender equality.
The results for the environmental dimension (PTCI_Env) show that two type 1 counties (‘Sierra de Aracena and Picos de Aroche’ and ‘Sierra de Segura’) and three type 2 counties (‘Los Alcornocales’, ‘Aljarafe Doñana’, and ‘Costa Occidental de Huelva’) present the most favorable situation. In all cases, these are regions with a high availability of natural resources, forest areas, and Protected Natural Parks.
The results obtained for the institutional dimension (PTCI_Inst) show that two type 1 regions (‘Arco Noroeste de la Vega de Granada’ and ‘Montes de Granada’) and three type 2 counties (‘Costa Noroeste de Cádiz’, ‘Poniente Granadino’, and ‘Estepa Sierra Sur’) are the best positioned. In the case of the type 1 counties, ‘Arco Noroeste de la Vega de Granada’ stands out from the rest because of the high investment made by institutions in public services, and ‘Montes de Granada’ because of the involvement of the private sector in the development of the county. In the case of type 2 counties, ‘Costa Noroeste de Cádiz’ also stands out for the involvement of the private sector, ‘Poniente Granadino’ for the high levels of public spending per inhabitant, and ‘Estepa Sierra Sur’ for the degree of civil, sectoral, and business associationism.
The results for the integrated spatial development dimension (PTCI_Space) show that two type 1 counties (‘Arco Noroeste de la Vega de Granada’ and ‘Montes de Granada’) and two type 2 counties (‘Costa Noroeste de Cádiz’ and ‘Vega Sierra Elvira’) have the most favorable position. In type 1, ‘Arco Noroeste de la Vega de Granada’ stands out mainly because of the increase in population flow in recent years and the high penetration of internet into the county’s households, while ‘Montes de Granada’ does so mainly because of the road connections through highways, motorways, and road links. In type 2, ‘Costa Noroeste de Cádiz’ stands out from the rest because of its population density, and ‘Vega Sierra Elvira’ because of its high per capita levels of internet access and its good road connections with the main city of the NUTS3 area.
The results obtained for the GTCI) show that nine type 1 and ten type 2 counties present the most favorable situation (those with indices equal to 100). These counties, the type of territory to which they belong, and their geographical locations are shown in
Figure 5.
Among this group of regions with an index equal to 100, “Arco Noroeste de la Vega de Granada” in type 1 and “Estepa Sierra Sur” in type 2 are the ones that are most often repeated as a reference for the counties that still have the capacity to improve. Knowing the set of counties that in each type of territory act as a reference for those that are not at the optimum level can be useful in identifying the factors and dimensions in which adjustments must be made to advance the processes of cohesion.
In coherence with the phases of the methodology,
Table 5 and
Table 6 present the results of the cohesion analyses performed in each type of territory between the factors and the global index of territorial cohesion.
In the case of type 1 counties, of the ten factors considered in the analysis, two of them are significantly and positively correlated with the global index of territorial cohesion. In both cases, these are factors related to the economic dimension. Thus, the results show that, in this type of peripheral and remote territory with significant demographic problems, those counties that have experienced the greatest economic growth, with high employment rates and economic dynamism and diversification, are those that acquire the highest level of territorial cohesion.
These results are in line with those obtained in other research conducted in the same geographical area as the one analyzed in this research [
20,
21,
85]. These studies show that the diversification of the economy is a decisive factor for the resilience, development, and cohesion of rural territories. Additionally, other studies that focused on another Spanish region [
69] and on the European regional level [
88,
89] highlight that diversification, innovation, and entrepreneurship act as drivers that contribute to the development of territories and regions.
In the case of type 2 counties, of the ten factors considered in the analysis, two of them are also significantly and positively correlated with the global index of territorial cohesion. One relates to the environmental dimension and the other to the integrated spatial development dimension. Thus, the results show that, in this type of territory with a more favorable geographical situation and demographic potential, those counties with quality environmental resources and connection infrastructures, both road and internet access, are those with the highest levels of territorial cohesion.
Factors relating to the availability of natural resources, the presence of forest areas, or high levels of biodiversity have also been previously identified as drivers of development in rural Andalusia [
20,
21] and in other European [
90] and North American [
91] areas. Similarly, factors associated with the accessibility and connectivity of rural territories and investment in transport infrastructure have proved to be decisive for the cohesion of rural territories in Andalusia [
21] and northern Spain [
92]
5. Conclusions
This research has made progress in the conceptualization of territorial cohesion, but, above all, in the design of a methodological proposal that allows an empirical approach to be taken to its evaluation and measurement, as well as to the analysis of the factors that affect it. To analyze the applicability and operability of this methodological proposal, the research was developed in the rural milieu of the region of Andalusia.
In this regard, it is important to note that the difficulty of a methodological approach to a concept that is still somewhat diffuse is compounded by others of an instrumental and practical nature, since studies of territorial cohesion at the regional level face a twofold problem: (i) Identifying smaller territorial units on which to perform analyses, and (ii) finding in those units the information needed to address them. Regarding the first problem, the two smaller units with administrative entities in Spain are the province (NUTS3) and the municipality (LAU2). However, neither of them is recommended for the analysis of territorial cohesion, since, in the first case, the internal heterogeneity of the unit is very high and includes both rural and urban areas, and the second case is too disaggregated for territorial studies. Consequently, it is necessary to identify intermediate territorial units that serve the purposes of territorial cohesion analysis. In the rural area, the units that have autonomy at that level for planning and promoting their development are the rural counties. However, in relation to the second problem previously mentioned, it is important to highlight that there is information that could further enrich the empirical analysis, but this is not disaggregated at the county or municipal level, which limits the possibilities of the study.
However, despite these difficulties, the proposed methodology has a number of features that make it practically useful and applicable in this and any other geographical area: (i) It is based on an extensive bibliographical review of both scientific literature and documents derived from the work of the main European institutions; (ii) it presents an integrated and holistic vision of the concept of territorial cohesion and the different dimensions that make it up; (iii) it simplifies the complexity of the concept and makes it operational and measurable; (iv) measurement is based on a careful selection of indicators and is performed in stages through the aggregation of elements facilitating the understanding of the analysis. In any case, it should be remembered that the methodological tools used to measure territorial cohesion only provide relative—not absolute—results, given that rural counties are classified and hierarchized by making comparisons between them.
This is a consistent methodology with significant potential in a context where data availability will tend to be increasingly immediate, thus ensuring the automation of monitoring in the evolution of indicators. Monitoring could contribute to improved decision-making by policymakers, leading to better design and implementation of interventions, assistance for more efficient resource allocation, and quality and transparency of achievements.
The results derived from the application of the methodology reveal some elements that promote processes of territorial cohesion in rural Andalusia. Specifically, in type 1 territories, the cohesion and development of their counties should be based on the diversification of the sources of income of the local population, taking advantage of the various opportunities offered by their natural and cultural heritage. This diversification should be based on innovation and entrepreneurship, including in the agricultural sector and the food industry, boosting local production activities, and seeking new value chains.
In type 2 territories, the challenge for cohesion is to understand that both rural and urban areas are part of the same territory. It is therefore necessary to intensify relations and connections between the two, making available to economic and social actors the appropriate resources and road infrastructure to make this interaction possible. Territorial planning, approached in an integrated and sustainable manner, which also takes into account the value of natural areas, should play a key role in avoiding the risk of imbalances in urban–rural relations in these areas.
In this respect, it can be concluded that high levels of economic growth, employment, innovation, and diversification of the economy, as well as the availability of both natural resources that provide environmental quality and infrastructure for road connections and internet access, are factors that contribute to the cohesion of Andalusian rural territories.
The results obtained also show that the relationship between these factors and the processes of territorial cohesion depends on the type of territory and its characteristics. These results highlight two important conclusions that should be taken into account because of their implication for the design of public policies: (i) Policies should incorporate in their proposals instruments that enable the promotion and activation of the specific factors that contribute to territorial cohesion, and (ii) a different territorial reality requires flexible policies that enable the correct use of the principle of subsidiarity. This flexibility implies objectives and measures adapted to different realities and prioritized in different ways in order to allow territories to move forward by acting on the problems that affect them and by relying on the factors on which they can base their development.
Finally, it is important to note that when territorial cohesion is understood as a path towards the reduction of disparities within the territory under analysis, a trend and dynamic analysis is required. Therefore, future research is required in which the proposed methodology is applied over a period of time to assess territorial trends (of cohesion or exclusion) in the rural areas of Andalusia.
