1. Introduction
The crisis of modern conventional agriculture is global, affecting the most advanced economies as well as those from developing countries. The current agricultural system applies capital and technology intensively in order to be highly productive and competitive, which entails a series of economic, social, and environmental issues [
1].
The economic issues directly affect farmers. Food prices have remained stagnant for a long period of time, whereas the costs of the products produced have increased significantly [
2]. This has prevented farmers with less resources from competing in this new market. In Spain, there has been a very significant decrease in the number of agricultural holdings, down from 3,000,000 in 1962 to 945,024 in 2016. However, agricultural land has not decreased in the same proportion, down from 44.6 million hectares in 1962 to 30.0 in 2016. Therefore, there has been a concentration of agricultural holdings, and thus, a decrease in the number of small holdings [
3].
The social issues are linked to the depopulation of rural areas. Industrialisation, implemented in the 19th century, has progressively decreased the needs for human labour in the agricultural sector, as well as the duration of all agricultural procedures [
4]. Due to this hurdle, in Spain, like in the rest of the world, there has been a mass rural exodus from the countryside to urban areas. In 1960, 43.4% of the Spanish population lived in towns with less than 10,000 inhabitants (80% of the national territory), a figure which has fallen to 19.9% in 2017 [
5]. Today, the activity of the rural population tends to cease being agricultural and instead diversifies, turning the rural economy into a service economy [
6].
Lastly, conventional agriculture entails a series of environmental issues, causing serious damage to the ecosystems such as soil degradation, water pollution, or the loss of biodiversity. Hybrid variety crops have proliferated around the world in recent decades with the objective of solving the productivity issues of traditional agricultural varieties, which lack the organoleptic properties that consumers want. These hybrid varieties have replaced traditional ones, which has entailed an extraordinary loss of genetic diversity due to the disuse of traditional varieties [
1,
7].
These issues can be seen in Spanish agriculture, which are greatly impacted by horticultural crops. The tomato stands out among them, as it is the horticultural crop with the most extensive surface (60,852 cultivated hectares) as well as the one that contributes the most to the production value of Spanish horticultural crops (almost 25% of the total horticultural crop value) [
8].
In this context, it is of interest to study alternatives that promote the sustainability of the territory by increasing the economic activity of rural areas, as well as preventing the significant loss of biodiversity in these areas. The alternative proposed in this paper is to considerer local and traditional species and varieties, because they cover a wide genetic diversity that can help mitigate the current genetic erosion within agricultural diversity, in line with SDG 15 (Sustainable Development Goals), “Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss” [
9,
10].
To do so, this article sets two main objectives: on the one hand, to detect and define the profile of potential traditional variety consumer segments; on the other hand, to determine the level of acceptance that tomato producers assign to a new and genetically improved traditional variety, and to analyse the importance that they give the various properties of this new traditional variety.
In order to achieve these objectives, consumers were surveyed by way of a choice experiment and several questions that make it possible to find and characterise segments. Meanwhile, tomato producers were interviewed in order to assess the acceptance of the cultivation of traditional varieties improved by way of marker-assisted selection and backcrossing.
3. Materials and Methods
3.1. Determine the Acceptance and the Most Influential Variables in the Consumer’s Purchasing Decisions
The research was conducted at the facilities of the Miguel Hernández University of the towns of Orihuela and Elche (Alicante province) in July 2017. The study was carried out with 217 people, evenly distributed in 3 different sessions. Convenience sampling was used to select participants, which is why the results cannot be generalised for the whole population [
32]. The characteristics are shown in
Table 1.
The information was obtained from a survey which includes a choice experiment. This technique is based on the idea that goods or services can be described by the attributes that they include, and which consumers make purchasing decisions based on [
33,
34]. The purpose of the choice experiment was to determine the relative importance of the different attributes and their weight on the choice of purchase.
Choice experiments arose from conjoint analyses, are consistent with the random utility theory, and are useful as a method for eliciting passive use values [
35]. The basic assumption of the random utility theory is based on the premise that individuals act rationally, selecting the alternative that yields the highest utility. Consequently, the probability of selecting a given alternative will be higher if the utility provided by such alternative is the highest among the different choices [
36].
Choice experiments are also called stated preference methods, and they refer to situations where choices are observed in hypothetical situations. These types of methods have the advantage that they can allow the analyst to model the demand for new products with new attributes for which there is no real preference history, as with our current research. Our product consists of two tomato “variants”: bred and nonbred.
The stated preference methods always require an experimental design. The design starts with the identification of the attributes and their levels, which allows us to define the products considering their most important characteristics and dimensions for the consumers in their decision-making process [
37,
38].
The attributes and levels of importance included in this experiment were chosen in accordance with the literature and the criteria of the researchers (
Table 2): type of tomato (bred/not bred), origin (local/foreign) [
39,
40], cultivation system (organic/conventional), and price (low/medium/high) [
41,
42].
After that, it was necessary to carry out the choice set design. Specifically, we started by generating a full factorial design for four attributes, three of them with two levels and one of them, the price, with three levels (2 × 2 × 2 × 3). As the set of options to be assessed by the participants was excessive, we reduced the number of choice sets with a fractional factorial design. The design and the subsequent analysis were performed with the JMP statistics program (SAS Institute, Cary, NC, USA). The final choice design was made up of eight choice sets with two alternative tomatoes (alternative A and alternative B) of the “De la Pera” variety and a third option representing the nonbuying option (
Table 3).
As well as the choice experiment, the questionnaire included a question where participants had to reveal their purchase preferences regarding a series of tomato attributes. This was conducted by way of a semantic differential scale (
Figure 2).
Among the considered attributes was the type of variety, with the choices being “hybrid” and “traditional.” This variable was used to segment consumers between those who prefer traditional varieties and those who prefer hybrid varieties.
A cluster analysis considering tomato variety preferences (hybrid or traditional) as the grouping variable was conducted in order to determine potential consumer segments. These preferences were disclosed by the consumers in the question on valued attributes. Once the segments were identified, consumers were characterised using the remaining variables to determine appropriate commercial strategies.
The survey also included the scale proposed by Steptoe [
43] to measure the underlying food selection motives: the food choice questionnaire, as well as other questions, to compile the sample population’s purchasing habits and sociodemographic data.
3.2. Determine the Variables that Influence the Cultivation Decisions of Farmers and the Socioeconomic Impact on Rural Areas
As the southeast of Spain is the main region regarding the production of fresh tomatoes in the country, the research focused on this area. To obtain the information, interviews were conducted with a structured questionnaire on 40 farmers of the area (
Table 4). Probability samples have a well-founded theoretical basis, but the requirements pertaining to random selection must be met in order to obtain them, which is not easy [
44]. As there is no tomato producer census, a probability sample was not chosen, and the sample is therefore not random. Producer contact information was obtained from a database that the Miguel Hernández University has, as well as from other sources such as the CAERM (Committee of Ecological Agriculture of the Murcia Region), some companies of the sector, and from the interviewees themselves.
The data was compiled between November 2017 and February 2018. The interviews were conducted two different ways: in person and by telephone. The interviews had an approximate duration of 15 to 25 min. Most questions were open-ended, but the interviewer had optional answers to help the interviewee if necessary. Some of the questions were quite straight forward, as they addressed the farmer and their holding’s socioeconomic data. The ones that took longer were the ones that inquired about traditional variety election criteria.
With the method used, an in-depth interview, the interviewer creates an environment where interviewees can express themselves freely. To do so, it is vital to make questions in a way that makes it possible to obtain the most relevant information for the interests of the research, while getting to know the producers enough to understand what they want to say [
45,
46].
The questionnaire used to conduct the interviews was produced by analysing the one employed in article [
47], adapting it to the specific objectives of the research, and consulting experts in crop production and genetic engineering. The questionnaire had 30 questions and was divided into three main blocks. The first comprised a series of simple questions on the distribution of the soil, the cultivation and farming systems, the number and type of workers employed, etc., in order to characterise the holding. The second block included questions linked to the cultivation of tomatoes, such as the reasons for cultivating or not cultivating traditional varieties, or the level of acceptance of a hypothetical new variety with various improvements in its attributes. Lastly, the third block was based on a series of sociodemographic questions about the farmer, which are necessary in order to segment the interviewed population.
Once the answers were compiled, the variables included were classified and interpreted, so that the answers obtained could be classified into categories. Afterwards, they were analysed using the IBM SPSS Statistics v.25 program (IBM, Armonk, NY, USA).
5. Conclusions
The current situation of agricultural producers is strongly conditioned by the profits of their activity. On the one hand, this situation leads to the abandonment of agriculture, because people look for more lucrative activities. On the other hand, this involves a change towards products that make it possible to obtain greater profits [
68,
69]. In the Mediterranean area, major and highly specialised holdings with specific crops (cucumbers, tomatoes, peppers…) are proliferating, whereas small and medium ones seek crops that allow them to survive, such as table grapes or broccoli [
70,
71]. All of this represents the abandonment of the cultivation of traditional varieties, whose preservation is essential to slow down the loss of biodiversity and preserve phylogenetic resources [
72].
With this initial situation, the study of consumers has identified two clearly differentiated market segments: consumers of traditional tomatoes (S1), and those who prefer commercial hybrids (S2). Therefore, we can confirm H1: there is a tomato consumer segment that prefers traditional varieties rather than hybrid varieties. This sector is characterised by giving greater importance to the organoleptic properties of a tomato than to its price, meaning that they are more willing to pay a higher price for this type of product. Likewise, this segment also values positively the local origin of the production and buys more frequently in greengrocer shops and open markets.
Meanwhile, research on tomato producers has identified three types of holdings according to their size: small (<5 ha), medium (5–40 ha) and major (>40 ha). The objectives of the major holdings focus on obtaining financial profits and, following general criteria, high-quality fruit (evenness and post-harvest preservation). However, owners of small and medium holdings are more concerned about the resistance of crops, the fruit’s organoleptic properties, and the positive assessment of the consumer. Likewise, obtaining these segments allows us to accept H2: there is a producer segment willing to cultivate an improved traditional variety. Small and medium farmers approve cultivating this product, which would preserve the excellent organoleptic properties of a tomato, an attribute that is highly regarded by S1 of consumers, while making it easier for them to carry out their activity (plants with resistance to viruses).
Therefore, it seems appropriate to propose the cultivation of improved traditional varieties to small and medium farmers, as they would find in the local market a segment of consumers who value them positively (S1). Regarding the marketing strategy, a good place to start would be to provide information at local points of sale, as they are the preferred place of purchase of the target segment. This information could materialise as printed advertising or as sales promotions aimed at both the end consumer and the distributor. Likewise, news items or technical reports could be generated and disseminated through different digital marketing tools on websites that specialise in local products. This would make it so that the work of small and medium farmers is profitable, preventing an abandonment of this activity and improving the territorial and economical sustainability of the rural world. Therefore, H3 is accepted: the cultivation of traditional varieties is a suitable alternative for the sustainability of the territory’s agricultural activity.
Meanwhile, major farmers are encouraged to cultivate very productive hybrid varieties, and to base their competitive strategy on the price, as there is an S2 segment of consumers who prefer hybrid varieties and assigns particular importance to low prices.
Furthermore, the cultivation of these traditional varieties aimed at local markets would make it possible to achieve a triple objective: contribute to the sustainability of rural communities, satisfy the demands of consumers regarding the protection of flavour and the environment, and help the health authorities find ways to promote the consumption of fruit and vegetables.
However, this study has some methodological limitations. On the one hand, the consumer study was conducted following a convenience sampling method, which implies that the results cannot be generalised for the whole population. Furthermore, the producer study could not be conducted with a random sampling, as there is no tomato producer census from where to select participants, and even though all segments were well represented, the obtained sample was not exhaustive. These limitations entail that this is an exploratory study. However, this research has shown that there is a market niche for the traditional tomato varieties, which are highly regarded by a certain segment of the population. This suggests that work can continue to be done in this line of research in order to consolidate the obtained results. Furthermore, few papers of this type have been published and, given that the results obtained in this study are optimal for the sustainability of the territory and the preservation of genetic heritage, we propose conducting new research on traditional varieties of other products spread across different geographical areas.
