Abstract

:
Coupled human–environment systems and traditional agricultural landscapes can be a key element in the conservation of biodiversity, ecological functionality, and cultural heritage. Terraced landscapes are a relevant example of traditional landscapes within the Mediterranean area, but they are now threatened due to the abandonment of agricultural activities. In order to identify factors that can affect the conservation strategies needed to maintain terraced landscapes in the Mediterranean area, we performed a literature review on studies about terraces and their management, soil erosion and vegetation dynamics after abandonment, etc. We collated a total of 285 scientific papers reporting 293 case studies in 19 countries. The majority of these studies analyze dry stone terraces and their influence on soil erosion and water runoff, either in cultivated or abandoned terrace systems. Only a minority of papers suggest maintenance or conservation strategies or involve farmers, exploring their decision-making. The conservation of terraced landscapes is in the hands of local farmers, and thus they should be actively involved in decision-making to find the most suitable strategies for assuring the continuity in farming and preserve cultural landscapes in the Mediterranean area.

1. Introduction

Most natural environments have now been replaced by coupled human–environment systems or social-ecological systems (SESs) [1]. If properly managed, SESs, such as many traditional farming systems, can retain high biodiversity and ecological functionality [2,3]. Cultivated terraces are considered one of the most typical and ancient traditional farming systems and are created to obtain arable land on steep slopes [4,5,6,7], contributing to reducing water runoff and soil loss [8,9] and simultaneously boosting biomass accumulation and soil water recharge [6,10,11,12]. These terraces are widespread across continents, from Meso-South America to Eastern Africa, South-East Asia, and Mediterranean Europe [12,13].
Terraced landscapes have become a central topic in international policies such as the UNESCO World Heritage List or FAO’s Globally Important Agricultural Heritage System (GIAHS). In Europe, terraced landscapes are protected through the Common Agricultural Policy (CAP) and other EU regulations, and farmers are eligible for funding to preserve them [14,15,16,17]. As a consequence of their relevance (hydrogeology, landscape, tourism, agriculture, etc.) [14,18], there has been an increase in studies focused on terraced agriculture. However, terraced landscapes can change dramatically due to the abandonment of agricultural activities, which are often highly demanding in these areas [19,20,21].
The preservation of terraced landscapes, as for other SESs, depends on a variety of factors, including human action [1,22]. The goal of managing the resilience, and thus the stability, of an SES is to “prevent it from moving into undesirable configurations” [23]. A main undesirable configuration of a terraced system is its collapse (i.e., terrace failure and landslides). According to the literature, several factors may increase the risks of terrace failure, such as the inclination of the slope, the soil texture, the position of the terrace within a valley, the presence of shrubs on drystone walls, and above all the abandonment of terraces [12,24]. In this review we aim to present the management activities that farmers use to maintain the stability of terraces; we also identify the conservation strategies that could promote the preservation of this cultural landscape around the Mediterranean area.

2. Materials and Methods

Between May 2019 and January 2020, we performed a thorough literature review on terraced agriculture. We built on reviews on the topic [12,24,25], and we conducted a search on the Internet for scientific articles using Google Scholar as a search engine and the following keywords “terrace agriculture Mediterranean”, “terrace agriculture interview” and “terrace agriculture” (alone and combined with all the names of countries in the Mediterranean, e.g., terrace agriculture and Spain). In this first phase, all papers selected for review were in English.
We then screened the references of all the papers that we found in order to refine our search until no new papers were found. In this subsequent screening, we selected English-language papers included in the referred scientific literature. We also considered a small number of relevant papers in the Italian language, and it is likely that we have not included a few papers in other languages that might have been relevant. We collated about 500 articles (published up to 2019–2020) that we culled to include only papers (N = 285) dealing with terraces (construction, management, vegetation colonization, etc.) within the Mediterranean area. We excluded those papers that only mentioned the presence of terraces in the area but did not analyze them in any way, as well as those papers that discussed the geological features of natural terraces (landforms). We built a database of all the remaining articles (N = 285) (Electronic Supplementary Material, ESM1 Table S1) detailing the type of terrace, the main focus of the paper, the country where the study was performed, and the management practices for the terraces.

3. Results and Discussion

There are different types of terraces which differ in shape, structure (e.g., inclination, risers), and construction material (e.g., stones, concrete, earth) [12]. However, they all share a common function of expanding cultivable land [26] with similar outcomes: they modify the landscape, hydrogeology, soil features, and system dynamics [24,25,27]. In the Mediterranean area, terraces are a defining feature of the landscape of many regions (Figure 1; ESM1 Table S1) as they are often quite ancient, built with construction techniques that have not changed much over millennia [25,26,28,29,30]. Here, dry stone terraces are the most common, predominantly built on marginal lands, and are now largely abandoned (Figure 2a; ESM1 Tables S2 and S3). The majority of the collated papers (ESM1 Table S3) analyze the changed conditions after abandonment: soil degradation or erosion, vegetation features and dynamics, and historical land-use changes, while only a few explore management operations or strategies for requalification (Figure 2b, Table 1, ESM1 Table S4). Other papers are mostly descriptive (analyzing landscape features or construction techniques) or analyze a variety of environmental conditions for actively cultivated terraces (ESM1 Table S3). Only a handful of papers compare conditions (i.e., soil erosion rates) in different agricultural systems [31,32,33]. Finally, a minority of the studies involve the participation of farmers, although they are one of the key elements that control the dynamics of the system.
In the analyzed studies, farmers were involved for different reasons and in various ways. Most papers include interviews with farmers to collect information on the management of the farm [34,35,36] in order to include firsthand data on crops, farm size, etc. Other papers also explore the economic aspect of terrace cultivation with the farmers [37,38]. Many studies instead aim to gather the farmers’ perspectives on the local terraced landscape [39,40], its history and changes over time [41,42,43], and on the landscape–tourism interrelationships in terraced landscapes [44,45]. As several collated studies focus on soil erosion, some researchers also include farmers’ perceptions on land degradation and the adoption of soil conservation practices [46,47]. On the other hand, not many studies analyze risks, strategies, or management needs with the involvement of farmers [38,43,48,49].
Although it is a shared view in the literature that the maintenance of terraces is essential for a variety of reasons (i.e., erosion control) [25], only a limited number of papers detail management strategies (Figure 2b, ESM1 Table S4). For instance, several papers indicate that dry-stone walls require maintenance without any specifics, although some report that farmers remove vegetation from the walls, keep waterways clear, or repair damaged wall structures [50,51,52]. Still, these three actions are never mentioned together within the same paper. Only a few papers describe management strategies for broad-base terraces with no built walls (stone or concrete), and they mostly suggest practices (i.e., no tilling and drip irrigation) that can reduce the dislocation of soil (erosion) and thus the destabilization of terraces [53]. Only a limited number of papers explore how plants growing on dry stone walls can affect their structural integrity, although some analyze how plants affect soil erosion on terraces with earth embankments [32,54]. Although many papers recognize the relevance of terraced landscapes and terrace systems, not many discuss what can be done to preserve them, indicating that papers analyze different issues and that implications for management are not well covered in the literature.
Several publications analyze soil features and erosion, or vegetation dynamics, after the abandonment of terraces (ESM1 Table S3). Terraces alter the drainage network of hillslopes and can become prone to erosion, piping, instability, debris flow, and landslides if they are no longer maintained [11]. The evolution of an abandoned terrace depends on its structure (slope, type of wall, bedrock, etc.), but it generally leads to various extents of geomorphic damage, especially when the recolonization of vegetation is disturbed [11,55]. Disturbing events such as fires can halt vegetation dynamics, favoring the establishment of small shrubs or herbaceous communities [56] that are less effective on terrace stability than arboreal vegetation when terraces are already in poor conditions. Often, studies evaluate linkages between the evolution of plant communities and soil stability [57,58,59,60], with different perspectives on the vegetation dynamics and terrace collapse [61]. Most of these studies focus on plant development on the flat surfaces of terraces, and only a few examine plant colonization on retaining walls [62,63]. Several researchers analyzed the main factors affecting plant cover and dynamics, investigating their linkages with the time since abandonment [51,56,57,64,65], aspect and edaphic conditions [60,63,65,66], and previous land use [20,58]. In several cases, after the abandonment, terraces undergo an increase in vegetation and species diversity [56,66], which can eventually recreate a natural landscape but not the cultural landscape.
The resilience and stability of coupled human–environment systems are often linked to human activities within the system [1,19,67,68,69,70]. According to the literature, soil erosion is higher in abandoned terraces, which are also more likely to collapse than those that are managed, with dire consequences for the hydrogeological stability of mountainsides [55,71,72]. Heavy rainfall events, which are becoming more frequent with current climatic changes [73], can also increase the risks of soil erosion and collapse within abandoned terraces [9,74]. Furthermore, the restoration of collapsed terraces is more expensive and difficult than periodic maintenance of the walls, which is mostly comprised of a few simple actions (Figure 2b). These actions can thus prevent, or at least reduce, the incidence of landslides and preserve the integrity of the cultural landscape [74]. How to incentivize the farmers to keep maintaining their terraces, however, is a different matter.
The Mediterranean area hosts many outstanding examples of terraced landscapes, though they are currently changing [18,25]. Many people are abandoning agriculture in marginal land, including the cultivation of terraces [24]. Several studies have suggested potential strategies to preserve or restore these landscapes, mostly focusing on economic incentives, community-based initiatives, and tourism [18,75,76] (Table 1). Some researchers instead suggest measures to facilitate the vegetation recolonization of abandoned terraces to reduce the erosion process and failure risks [53,59,77]. However, this suggestion does not always consider the value of terraces for the preservation of cultural landscapes. The reconstruction of terraces is often controversial, as restoration does not always adhere to traditional construction techniques [24]. There are several options (Table 1, Figure 3) that can be used to encourage farmers to keep maintaining their terraces, although some options might not be feasible for all regions within the Mediterranean area.
The literature suggests a variety of options for the conservation or requalification of terraced landscapes. There is a first distinction here, as most studies suggest strategies both for abandoned and cultivated terraces, while other studies suggest that the efforts should be focused on cultivated terraces and renaturalizing abandoned ones [78,79]. In some studies [15,17], researchers recommend the use of financial incentives to rebuild or sustain agriculture on terraces that are generally less lucrative than conventional agriculture. Financial support would easily solve the problem of terrace abandonment, but this option is not easy to implement due to lack of funding at a national level. Other studies suggest the cultivation of new profitable crops [80]. However, the farmers that still cultivate their terraces do so because often they adhere to their local traditions and want to keep cultivating their traditional crops [71]. They will likely need to be encouraged to embrace a multifunctional use of terraces, including the cultivation of new crops [81]. The promotion of touristic activities would be beneficial if specifically tied to terraces and agriculture, because if the tourism sector were to become more lucrative than agriculture, it is likely that people would abandon their farms and terraces. One further option that has been suggested by some researchers [82,83] and has been successfully applied in Italy [84] and outside of the Mediterranean area [85] entails the possibility of renting terraces to hobby farmers and city dwellers.
As terraced systems are coupled human–environment systems, options for the requalification of terraced landscapes should be tailored to the local needs of farmers. Most studies simply advocate for the involvement of local communities in planning, and only a few analyze successful community-based conservation projects [86,87]. These two projects involved farmers in all the activities, from the decision-making to the implementation of the selected management actions. As mentioned above, in the Brenta Valley (Italy), terraces were rented to people interested in hobby farming so that they could maintain the terrace structures. Other researchers [78] have described the measures adopted for the restoration/conservation of terraces in a management plan for a terraced area. As an example, the potential use of ethnobotanical plants, which are tied to local traditions, in combination with new crops that can increase farmers’ incomes was suggested for the management plan of the Amalfi Coast to foster the preservation of its cultural landscape [81,88]. Finally, two studies [89,90] describe a project involving a local school where students and teachers were involved in restoring a portion of a terraced landscape. Even though there were not many factual examples of local involvement, all of these projects were successful and resulted either in the restoration or in the preservation of a terraced landscape.

4. Conclusions

The periodical management of terraces entails inexpensive and simple, although possibly labor-intensive, actions (i.e., plant removal from terrace walls) that require the active presence of farmers. There is no study, at least in the Mediterranean area, that analyzes how effective these strategies are for the stability of terraces. On the other hand, several studies have demonstrated that the involvement of local farmers and stakeholders is pivotal for the success of conservation/requalification projects. As such, the conservation of terraced landscapes is in the hands of local farmers, and thus they should be actively involved in the decision-making and finding the most suitable strategies for assuring the continuity in farming and preserving cultural landscapes in the Mediterranean area. As terraced landscapes are widespread across the globe, the challenges, management strategies, and conservation options for terraces are diverse, and we advocate for expanding our review to a global level to explore successful strategies for preserving terraced landscapes.
