1. Introduction
In 1991, the European LEADER Initiative emerged, executed under a model of integrated, endogenous, and innovative rural development [
1,
2]. This initiative sought to develop European rural areas through their economic diversification, according to the characteristics and needs of the territory of action, the population that inhabits it, and the exploitation of its endogenous resources [
3]. The LEADER approach began as the basis of a pilot project and became an axis of action of the Rural Development Policy 15 years later, continuing its operation today through the management of the local action groups (LAGs) [
4], which design the development strategies and manage the financial resources to subsidize the projects. Therefore, for more than 30 years, European rural regions, such as the one covered by this work, Extremadura (Spain), have been beneficiaries of an innovative and alternative development model to the traditional one of public aid management by incorporating the local population in decision making and strategy design [
5,
6]. As Staic and Vladu state [
7], the LEADER approach supports the European objectives for rural development taking into account the territorial dimension and encompassing the principles of bottom-up endogenous development and community empowerment [
8]. LEADER is a working methodology based on three parts: strategy, territory, and partnership meant to revitalize and enhance the rural environment through the prominence, autonomy, and responsibility of the rural population [
9]. Exactly, the principles of the LEADER approach, which help to understand its operation, are [
10]: local development strategies by areas, designed for clearly delimited rural and subregional territories; local partnerships between the public and private sectors or local action groups; a bottom-up approach that gives LAGs decisive power in developing and implementing a local development strategy (bottom-up strategy); cooperation and multisectorial application of the strategy, based on the interaction between agents and projects in different sectors of the local economy; implementing innovative approaches; the execution of cooperation projects; creating a network of local partnerships. Since the creation of LEADER, this approach has worked, with changes attending to the political and territorial needs of the European rural environments, during the following programming periods [
4]: 1991–1993 (LEADER I); 1994–1999 (LEADER II); 2000–2006 (LEADER+); 2007–2013 (Axis 4 of the European Agricultural Fund for Rural Development (EAFRD)—LEADER approach); 2014–2020 (LEADER as a participatory local development strategy (PLDS)). In Spain, the country to which the study area of this work belongs, PRODER (Programa Operativo de Desarrollo y Diversificación Económica de Zonas rurales) was created in 1996 to cover all Spanish rural territories, operating under the same parameters as LEADER.
LEADER has generated innumerable benefits [
11,
12,
13,
14,
15]. However, there are regions, such as Extremadura, which, despite its long history as a recipient of rural development aid, has rural areas that are among the oldest and most depopulated parts of Spain. Its gross domestic product (GDP) is still less than 75% of the European average, and it exhibits lower socioeconomic data than the most dynamic Spanish regions [
16]. Since the 1980s, the population of Extremadura has been stabilizing in its places of origin; however, demographic and economic growth is limited to the population centers located in urban and irrigated areas, in their areas of influence, and in places where a productive non-irrigated crop of vines and olive trees is exploited. In contrast, the municipalities with the lowest and aging populations, which are located in the mountain areas, peneplain, non-irrigated areas, and pasture lands in the south of the province of Badajoz, continue to experience demographic losses. Given this, several authors [
17,
18,
19,
20,
21] have affirmed that, in this region, there are still areas in which LEADER has not generated expected results. These areas have a scarce industrial and business fabric; are far from the main centers of population, leisure, and consumption; and, above all, still have the regressive demographic and social conditions with which they started. Since the beginning of LEADER, the largest number of projects and those with the biggest investments are concentrated in rural areas with more population and development, with a self-sufficient business fabric and with actors capable of co-financing projects. These areas are, mainly, the county seats of the region. Thus, as stated by Nieto and Cárdenas [
15], in Extremadura, there is a clear positive discrimination of aid for rural development toward the most demographically and socioeconomically dynamic rural areas. This statement is supported by the results obtained in research on the regions of Andalusia [
22,
23] and Galicia [
24], in the case of Spain, or on other European regions [
25,
26], highlighting the study of Olar and Jitea [
27]. Given the conclusions of these works, as Pérez and Guzmán affirm [
28], the good results expected with the implementation of LEADER in various European rural areas seem more of a wish than a reality.
Most of the works cited show, from a quantitative perspective, where the funds are located and concentrated and where the greatest number of projects are launched, leaving in the background those municipalities or regions in which less is invested via LEADER. In the case of Extremadura, this work contributes by identifying the municipalities to which the aid for rural development should go. In other words, this work explains, from a geographical perspective, where the municipalities should be located according to the objective pursued by the EAFRD: to improve the socioeconomic conditions of European rural areas to reduce the processes of aging and depopulation.
Therefore, LEADER investments must be made after analyzing different variables that guarantee an adequate social and economic impact for the protection and development of the rural population that most needs such funds and aid. For this, the implementation of multicriteria analysis methods and GIS tools that facilitate the geographical analysis of a series of selected variables is proposed. These tools and methods will enable making the best decision in accordance with established criteria to assess which Extremaduran municipalities need LEADER and provide them the greatest economic and spatial efficiency; economic, social, and territorial equity; environmental justice; sustainability; competitiveness; quality of life; welfare; and social and territorial cohesion [
29,
30,
31]. In short, the objective of this work is to determine which areas are the most convenient, optimal, or priority municipalities for receiving aid for rural development because they have regressive characteristics, such as a smaller population, low demographic growth, a low birth rate, a high mortality rate, high population aging, a low productivity index, high unemployment rates, low accessibility to urban centers, and few investments and projects executed under the LEADER approach. This will be achieved by creating an optimal location model as a result of an analytic hierarchy process (AHP) and, subsequently, a weighted overlay multicriteria analysis (WOMA) in a GIS. Information and tools will be generated to direct the scarce financial resources from the EAFRD through LEADER to promote a planning process for rural development in Extremadura.
Multicriteria evaluation (MCE) is a set of techniques used in multidimensional decision and evaluation models [
32]. One of the techniques is the AHP, which is used in this research. Saaty, whose objective was to support a reduction in the number of nuclear weapons of the Soviet Union and the USA [
33], developed the AHP in the late 1970s. To structure and organize the processes, this method develops a hierarchical structure for decision-making, allows choosing the best alternative from a set of alternatives based on given criteria [
34], and helps to mitigate the possible conflicts of subjectivity. Thus, the AHP is considered an internationally accepted weighting method given the advantage it offers by allowing quantitative and qualitative elements to be mixed, enriching the decision-making process [
35].
Traditionally, MCE has been applied to the environmental field [
36,
37,
38,
39,
40,
41], since many factors influence it, but it has also been applied in areas of a social nature [
42], such as rural development. Most social problems do not have unique answers but are linked to each other and to what the researcher wants to study. Hence, works that identify optimal sites for locating activities such as tourism [
43], public facilities [
30,
42,
44,
45], or even social services for certain groups [
30,
42,
44,
45,
46] stand out. Extremadura being the study area, MCE has been used for the location of second homes in its rural environment [
47]. In addition, there is the work of González-Ramiro et al. [
48], in which, through the AHP, they determined the potential of rural tourism in the region. Guillén, Hernández, and Sánchez [
49] carried out an interesting application of the process in order to analyze the tourist destinations of Extremadura.
In the preceding decades, the development of the multicriteria evaluation methodology, applied in creating optimal location models in the 1970s [
50], and of geographic information technologies (GIT) has led to the search for a combination of both. There are interesting GIS tools of great utility [
51] to address, for example, environmental, economic, social, and health issues, such as the WOMA, in a raster environment. In this combination of multicriteria evaluation and the GIS, studies dedicated to decision-making in the territory acquire relevance, especially in solving problems in urban areas [
52,
53,
54]. Although the use of multicriteria evaluations and their application through the GIS in the social field or human geography has been consolidated over the years, in the case of rural development, it can be considered novel since it has been analyzed, generally, from a quantitative but descriptive perspective and not statistically.

3. Results
After the previous methodological process, the optimal location model of LEADER investments in Extremadura was obtained (
Figure 5). In the model, the municipalities of the region appear according to their value as optimum, very suitable, acceptable, or unacceptable (
Figure 6), i.e., which municipalities have the worst data in terms of population, population growth, birth and mortality rates, aging and productivity rates, unemployment rate, accessibility to urban centers, and investments and LEADER projects, and vice versa.
Table 7 shows the number of municipalities in each category or an alternative to the model.
There are 12 Extremaduran municipalities that are optimal for receiving aid for rural development due to their regressive demographic and socioeconomic situations and for being the ones that received the least investment from LEADER in the period 1994–2013. These represent 3.09% of the municipalities of the region and are located in Miajadas–Trujillo (2 municipalities), Villuercas–Ibores–Jara (3 municipalities), La Serena (3 municipalities), and La Siberia (4 municipalities). These 12 municipalities are located in bordering territories in the southeast of the region, as can be seen in the location maps displayed in the
Section 2.1 (
Figure 1 and
Figure 2) and in
Figure 5. In addition, they are far from the main regional communication routes and those of the main Extremaduran cities and are traditionally the least developed demographically and socioeconomically at the regional and state levels. Along with them, it is necessary to highlight 168 very suitable municipalities (43.30%), which also have unfavorable characteristics, without forgetting the 46.13% that appear to be suitable. In total, there are 359 municipalities for which it would be convenient to bet on the rural development strategy of Extremadura but we are emphasizing those with the worst situation. The 12 optimal ones have had, during the analyzed period, an average population of less than 1000 inhabitants (some of them have less than 200 inhabitants), negative population growth (around −20%), birth rates below 4%, and mortality rates between 20 and 50%. Moreover, they have had aging rates over 500, productivity rates below 70 (the highest value in the region is 9,453, in Belvís de Monroy, in Cáceres), and unemployment rates around 15–20%; require more than 40 min of travel to reach urban centers (due to their border nature within the region and due to the poor conditions of the transport system); and have had an average of four subsidized projects throughout the period 1994–2013, with a total average investment of EUR 169,000. It is necessary to point out that Risco (La Siberia) has not been a beneficiary of any aid in the 20 years analyzed, while Olivenza (protected by the LAG Olivenza), Azuaga (Campiña Sur), and Miajadas (Miajadas–Trujllo) have received more than EUR 13,000,000 million, with 219, 399, and 468 projects, respectively. Furthermore, it is necessary to know that the average number of projects has been 30 and the average investment EUR 1,500,000.
Contrarily, there is one municipality valued as unacceptable. It is located in Las Vegas del Guadiana, and, although it does not have such a high number of projects and amounts invested as in the cases described above, it does have good statistics regarding the demographic and socioeconomic variables introduced in the model. This LAG is located in the most productive irrigated areas of Extremadura and in which, for decades, an important agribusiness has been installed and exploited, which explains why so much is being invested in the area. In this LAG, there is one city, Don Benito, that is, with respect to the number of inhabitants, the fifth city in the urban system of Extremadura, and in the coming years, it will join the neighboring town of Villanueva de la Serena, and they will become the third region city. This will reinforce its character as a focus of economic and demographic attraction at the regional level.
Hence, through the model obtained, it is possible to identify specific municipalities that should be beneficiaries of greater aid for rural development, given that, over the past years, the subsidies have been destined for those municipalities that needed it least because of their demographic and socioeconomic characteristics. In addition, the conclusion can be reached that most of the projects subsidized through the LEADER approach in Extremadura and that large amounts of money have been concentrated in a few municipalities that have the most favorable demographic and socioeconomic characteristics of Extremadura.
4. Discussion
Throughout the years it has been a beneficiary of European aid for rural development, Extremadura has experienced an unequal distribution of aid, even after changing the regulations in the successive programming periods in search of better strategies and fund management. This has been confirmed in various investigations that analyze the functioning of rural development policy in European territory, such as [
76,
77,
78], and through the results obtained in this study. On the basis of the optimum location model developed, the objective set has been achieved satisfactorily, that is, locating territories that do not receive aid for rural development. From a more economic approach to development, it can be considered logical and sustainable that more development is generated from businessmen and entrepreneurs already settled in each territory [
79,
80]. However, this causes investments to be grouped in already developed areas, leaving aside the municipalities that most need the implementation of new activities and the diversification of their economies. This same problem occurs, specifically, in the tourism sector. There are studies that reach the conclusion that a large part of the aid for rural development is aimed at rural tourism and that it is significantly concentrated in a few areas [
18,
81]. For example, it is a problem in coastal areas in Spain [
82], where the establishments with better advice and a higher level of infrastructure tend to receive most of the aid at the expense of small rural accommodation, most of which is managed by families, with little training and whose income is complemented by other activities.
Finally, despite the great effort of the LAGs in designing their strategies, the “most powerful” groups and the most solvent businesspeople with prior experience, influence, and power are shaping their ideas. For this reason, studies such as this one are necessary to find out not only where and how the aid is directed but also where it is not. Taking into account the objective pursued by LEADER, it is contradictory that, in Extremadura, the more rural and disadvantages municipalities are the ones that receive the least support from the EAFRD. In order to identify these municipalities, it is necessary to take into account the multiple geographic variables on which decision-making must depend in the design of development strategies. Furthermore, it is essential to choose the most appropriate methods of analysis, such as the ones used in this work: the multicriteria evaluation analysis through the hierarchical analysis process and weighted overlay and the advantages of a GIS for spatial and location analysis.
In this way, applied geography is practiced in the study and analysis of rural development in Extremadura, until now done from a more descriptive perspective [
3,
14,
83,
84]. In addition, we approach the purposes of territorial planning and management pursued by the Structural Funds and European Investment Funds (ESI Funds) through “a set of concerted actions to guide the transformation, occupation and use of geographic spaces seeking their economic development taking into account the needs and interests of the population, the potential of the territory and the harmony of the environment” [
85]. The multicriteria methods chosen in this study are an excellent tool that can be integrated with GIS instruments since they allow standardizing different types of geographic variables and greater integration that, otherwise, could not be taken into account in decision-making with spatial analysis. Although the methods applied are adequate, it is necessary to take into account that, on occasion, doubts may arise about the type of criteria/factors chosen in the multicriteria evaluation analysis and about the importance given to each one [
86]. In this context, the multicriteria evaluation analysis, specifically the AHP, was used as a methodological tool to help decision-making in the fill of rural development in Extremadura to be more consistent, transparent, and legitimate and to avoid variability.
In the field of rural development, and more specifically in the distribution and allocation of public aid, it is vital to have adequate information to make the best decision, and it is a complex and delicate process in which the subjectivity and dependence of the information play a preponderant role. This and the results obtained justify applying true rural development in Europe, and specially in Extremadura, based on the design of strategies that have a multitude of geographical variables that characterize each territory, in order to achieve the desired sustainable rural development that leads to better demographic and socioeconomic conditions for the most ruralized.
Regarding the methodology used, the results of this research show that multicriteria analysis methods together with spatial analysis GIS tools allow obtaining good and adequate results and are versatile and adaptable to various fields of knowledge [
87], not only the traditional ones, such as environmental or economic, but also the social and humanities ones, which also encompass problems in which multiple variables intervene, such as rural development. The implementation of rural development policy in Extremadura has been extensively analyzed, but using different methods to the one used in the present research, i.e., Nieto and Cárdenas applied principal component analysis [
21] and Local Moran’s I and Getis Ord cluster analysis [
15], obtaining different groups of municipalities according to LEADER aid and projects. After an extensive search, no studies have been found that analyze rural development through an AHP, which revalues the present one.
According to the objectives proposed by LEADER, it is clear that the results need to be evaluated from a quantitative perspective, for example, in terms of the number of projects. In fact, in Spain, as stated in the
Section 1, various regions have been the object of analysis, such as Cantabria [
88] and Castilla–La Mancha [
89,
90]. In these studies, LEADER is analyzed mainly through the basic territorial distribution of aid, the measures to which they are directed, the types of promoters, jobs created, etc., and the results are enlightening, but it is considered essential to relate them statistically with the demographic and socioeconomic context of the territories on which LEADER acts, as is done in this research. On the other hand, others authors, such as Navarro, Woods, and Cejudo [
91], study the social aspect of LEADER, as well as Márquez et al. [
92].
5. Conclusions
During the last 30 years, an interesting, innovative, and alternative development model to the traditional management of public aid has been applied in European rural areas, involving the transformation and reconstitution of public action through the incorporation of the local population in decision-making processes. Together with it, LAGs have been in charge of the design and start-up of the development strategies of their territories of action and the benefits generated are unquestionable. However, these have not been enough to prevent an unequal distribution of aid for rural development or the fact that some municipalities benefit more than others that have worse demographic and socioeconomic conditions, such as the case of the Spanish region of Extremadura. Nonetheless, in this work, we want to prove that LEADER is more than adequate for the management of rural development aid for its bottom-up approach and for its struggle to involve the population in development processes. Perhaps the rest of the European funds and policies should take LEADER as an example and apply its actions taking into account the needs of the population to feel safe and supported in their regions, as well as working together, since the objectives are the same, speaking then of territorial rather than rural development. For this, the work of the LAGs is essential. They faithfully know the weaknesses, threats, strengths, and opportunities of their territories, so they deserve greater freedom to design strategies and to reduce their bureaucratic burdens. In addition, more EAFRD action measures should be managed under the LEADER approach, so that the entire population, whether farmers, artisans, ranchers, or owners of a restaurant, is economically backed. If the population is aware and participates in the development processes, it will be feasible to bet on their place of origin, keeping the rural environment alive.
It is difficult to find a way to solve the fact that there is an unequal distribution of European funds for rural development in regions such as Extremadura due to the difficult situation of rural areas and the great complexity of the development processes. However, in this paper, a tool is presented that can serve in decision-making and in the supply of aid in an optimal way, so that a demographic and socioeconomic evaluation of the territory of action is necessary before distributing and weighing the projects to be subsidized.
Finally, as a future line of research, one aim is to continue investigating the demographic and socioeconomic variables that characterize rural areas in Extremadura and whether they influence the perception of aid for rural development. The model developed in this research will continue to evolve, since it is also intended to analyze the European programming period 2021–2027 and whether the same trends will continue in terms of aid through the LEADER approach. Thus, it will be possible to provide a tool with which the final distribution of aid is the most logical, fair, and sustainable possible for the benefit of the European rural environment.
