ARTICLE IN PRESS Land Use Policy 22 (2005) 103–114 Policy impact on desertification: stakeholders’ perceptions in southeast Spain Juan J. Oñate*, Begoña Peco ! Department of Ecology, Universidad Autonoma de Madrid, 28049-Madrid, Spain Received 10 March 2003; received in revised form 9 January 2004; accepted 14 January 2004 Abstract Two related land use change dynamics characterise the Guadalent!ın basin (southeast Spain) as one of the most severe cases of desertification in Europe: (1) expansion of highly productive irrigated agriculture in the valley, and (2) intense contemporary changes in the surrounding impoverished dry lands. On the basis of documented information, we trace the effects of past policies on these dynamics, illustrating such role with the results of 25 in-depth interviews on the issue with relevant stakeholders in the area. In line with relevant related research in other parts of the Mediterranean, our conclusion is that implemented policies have overemphasised the economic dimensions of development at the expense of environmental sustainability, specifically targeted policy instruments having failed to address the issue of desertification. Given this experience, it is estimated that only strict environmental policy enforcement together with people education could bring the situation under control. r 2004 Elsevier Ltd.

Keywords: Desertification; Policy impacts; Stakeholders; Agriculture; Irrigation; Spain Introduction Desertification is a complex process of land degradation reducing land productivity and the value of natural resources because of adverse human actions and climatic variations. Identified as a global problem in the 1970s (UNCOD, 1977), the need to combat desertification was also quickly recognised in Mediterranean countries (i.e. Portugal, Spain, Italy and Greece) of the European Union (EU) (Fantechi and Margaris, 1986; UNCCD, 1994). Great efforts have been made by the EU to understand the physical processes involved in desertification at a pan-Mediterranean scale (see review in Geeson et al., 2002) and the contributing socio-economic factors (Fantechi et al., 1995; CEC, 1997). To date, however, land use scenarios have often used top-down rationalisations of the process, assuming that once a policy is formulated it automatically has a beneficial outcome on the ground. This has neglected the necessary integration of perceptions, decision-making and varied responses to policies by actors ‘on the ground’ (Lemon and Seaton, 1999), often leading to an incomplete understanding of *Corresponding author.

We focus here on the society-driven aspects of the problem (van der Leeuw, 1998), under the assumption that the development of regional and local scenarios and feasible strategies and policy options to fight desertification can only be approached through the comprehension of the context within which individual decisions are made. The consideration of the perceived nature of the problem and effects of past policies by the major stakeholders in the policy arena is our first step towards these objectives. This paper reconstructs the effects of past policies on desertification in the Guadalent!ın basin (southeast Spain) on the basis of documented information and the discourses of interviewed selected stakeholders at the national, regional and local levels.

Administratively, most of the area is in the Murcia region with a minor part in Andaluc!ıa (Fig. 1). Two main dimensions characterise the Guadalent!ın as one of the most severe cases of desertification in the northern Mediterranean: (1) surface and groundwater overexploitation (CHS, 2001), soil salinisation (Vela et al., 2002) and natural habitat destruction (Mart!ınez and Esteve, 2000) along with a massive increase of irrigation agriculture in the valley in recent decades to the present 48,000 ha (CEH, 2001); and (2) intense erosive dynamics in the hilly dry land zones, rooted in historical land use changes acting on a sensitive combination of semi-arid climate and vulnerable soils ! ! (see details in Lopez-Berm udez et al., 1997). The spread of irrigated land is part of a regional trend (Fig. 2), now almost 31% of the regional Utilised Agricultural Area, more than two-fold the national level (MAPA, 2001). Horticulture production and related activities have driven a process of remarkable economic development,1 which has been the focus of resources and attention at 1 In the 1975–1996 period, the primary sector in the region grew at a rate of 4.3%, while the growth of the entire regional economy was only 2.98% (MINHAC, 2000). As a result, in 1999 the share of the primary sector in the Regional Gross Added Value was 8.9%, double the national figure of 4.2% (INE, 2000). Our point of departure is that desertification problems in the Guadalent!ın are rooted in certain physical circumstances—a semi-arid climate, available groundwater and highly erodable metamorphic and sedimentary rock—in which historical trends of land use, social and technological change have developed. Development paths before and after EU accession in 1986 have exacerbated two related land use change dynamics, considered proximate causes of desertification: expansion of irrigated agriculture in the valley, and intense changes in the surrounding dry land areas. The former is a main driver for aquifer depletion in semi-arid climates, leading potentially to both boreholes drying up and aquifer salinisation, in a similar equation to that faced in the Greek Argolid valley (Lemon et al., 1994). The latter include both intensification and abandonment of agricultural practices as well as sudden changes in crop choices following the more rewarding EU subsidies, which effects on erosion rates have also been reported elsewhere in the Mediterranean (Kosmas et al., 1997). On the basis of documented information and our own work (Cummings et al., 2001), our first interest was to reconstruct the role of past policies in these processes, considering as well the perception of such effects by stakeholders relevant to the issue (see next section). In particular, the role of a set of recent instruments which could have tackled the problem, such as agri-environmental and agri-forestry schemes, hydrological corrective measures and forestry measures and land use planning policies, was investigated. In-depth interviews In order to contrast and illustrate the rationale of our approach, the perception by selected stakeholders in ARTICLE IN PRESS J.J. Oñate, B.

Secondly, an analysis of stakeholders’ perception of desertification is dealt with, useful to provide a context for the interviewees’ discourse on our approach. The next two sections focus on the reconstruction of the origins (historical trends) and contemporary reality (policy choices and resulting processes) of land use change dynamics. The role of the recent policy instruments that could have tackled the problem is then explored in section five. Finally, the main conclusions of the research and the prospects for future action are summarised. Thematic area Category Background Perceptions of desertification Historical trends in land use change in the area Contemporary land use changes and ultimate effects—the policy impacts Irrigation expansion and related processes Changes in dry land and related processes Effects on desertification Role of recent policy instruments Agri-environmental and agri-forestry schemes Hydrological corrective measures and forestry measures Land use planning and related policies Power structure and politics of the network of interviewed stakeholders regard to both the nature of the problem and the effects of past policies on desertification was acquired by means of face-to-face semi-structured and taped interviews. Pursuing the development of an holistic view of the issue, an appreciation of the variety of perspectives was considered essential (Lemon, 1999). Twenty-five relevant stakeholders were selected, including governmental representatives at the national (six interviewees) and regional (7) levels, farmers’ organisations (6), academics (4), private corporations (1) and non-governmental organisations (1). Appendix A shows coding and affiliation of interviewed stakeholders. Existing contacts at the governmental levels acted as ‘sponsors’, facilitating access to most administrative officials, some of who in turn suggested ‘snowballing’ contacts (Lemon, 1999) from farmers’ organisations and private corporations. We directly contacted the remaining interviewees. The interviews were roughly organised around thematic areas and categories (Table 1), reflecting the rationale of our approach. A semi-structured approach (Lemon, 1999) was adopted, combining closed questions for the analysis of, e.g., the perceptions of desertification, and the flexibility of more open questions targeted at capturing the stakeholders’ discourse in regard to the effects of past policies on desertification. In order to reinforce the discursive nature of our paper, particularly emphatic quotations from interviews have been included in the text, balancing their number among interviewees for the sake of objectivity. Relationships between interviewed stakeholders seem to be primarily a function of both the power structure prevailing amongst the representatives of the administration and the historical and present status of the irrigation issue in the region. The 1978 Spanish Constitution decentralised government, sharing power between the central (hereafter ‘Nation’) and the regional governments or Comunidades ! Autonomas (hereafter ‘Regions’). Since 1982 the Region of Murcia has become responsible for the legislative development and implementation of several aspects covered by this paper (Table 2). In agriculture, the National role is now limited to liasing between the EU Regulations and Regional performance and co-ordinating inter-regional initiatives. Real power lies thus with the regional Agriculture Departments. The Nation does, however, still have considerable power over water resources through the River Boards, which under the 1985 Water Act must design their respective Hydrological Plans, administrate and control public water resources, uses and the infrastructure ! Hidrografica ! financed by them.2 The Confederacion del 2 Segura (CHS) is responsible for the 18,815-km Segura River basin, including the Guadalent!ın sub-basin. Under the Franco dictatorship, the Ministry of Agriculture, promoting land use transformation, and the CHS, regulating and supplying water resources, failed in overcoming, with the development of infrastructure plans, the historical ineffectiveness in consolidating and guarantying existing irrigation (CHS, 2001). The ‘irrigation problem’ had therefore already arisen well before the establishment of the Regional Government. From the point of view of national representatives (i.e. interview respondents 5.NAd1, Source: Authors. Structure of the paper We have structured the paper in six main sections. Firstly, we shall describe the context in which the network of interviewed stakeholders is inserted, needed to understand the power structure and politics among 2 Having formerly belonged to the Ministry of Public Works, in 1996 water authorities were transferred to the newly created Ministry of Environment, a change with no visible effects on the overall approach to water management in Spain.

Regional authorities, on the contrary, argue that the problem was a legacy they are trying to resolve. Nonetheless, respondents 12.RAd2 and 16.RAd6, both national administration civil servants ‘‘transferred’’ to the regional level, have confirmed that autonomous functioning has been considerably worse than the previous centralistic one, pointing to lack of experience, the political direction of the leaders, proximity to the voter and shortage of means and financial resources, as the main reasons. No additional justification of these claims has been found in published literature. In spite of the CHS being classified as ‘national administration’, the rest of stakeholders, including academics, still consider it responsible for the ‘irrigation problem’ claiming that the CHS has abandoned responsibility on issues such as groundwater control or water quality. The CHS representatives in turn, assert that regional administration has kept on promoting irrigation and encouraging farmers’ demands for water, while not having controlled industrial and urban sewage. Besides, the CHS officials themselves also argue that rigid implementation of the law provisions on water control has been unaffordable due to the poor economic and human resources available to the CHS. Irrigation as a major regional interest is now unanimously supported by the entire regional administration and, although recognising the negative effects of its uncontrolled increase on their respective issues of competence, both environment and physical planning departments act as subsidiary to this objective, claiming lack of effective powers to tackle the problem. All interviewed stakeholders expressed their opinions under the expectations raised by the recently enacted National Hydrological Plan (NHP), which foresees a huge investment in infrastructure for water transfer from the Ebro River basin (northeast Spain) to Murcia and neighbouring regions (MIMAM, 2001a). In the face of heated debate and protests at the national level (Saur!ı and Del Moral, 2001), expectations of new water supplies have spurred most of Murcia society to support the NHP, to the point where critics such as environmentalist groups and a few academics are branded as ‘traitors’ of regional interests. Also largely debated, a National Irrigation Plan, scenario 2008, was passed in April 2002, foreseeing no new irrigation expansions for Murcia, just enhancements of existing ones (MAPA, 2002), and consequently water transferred from the Ebro is in theory to cover the environmental deficit in the basin. However, coastal tourism and recreation have appeared as alternative development options for the Region (MINHAC, 2000). Announcing the farm/tourism conflict over water already apparent in the nearby Marina Baixa district (Mata-Porras, 2000), many in the Region (including most interviewed farmers) are suspicious of the real destination of transferred water resources. Perceptions of desertification The stakeholders’ responses, which sometimes mix concepts and causes, clearly reflect the ambiguity and broad scope of the term, implicit in the vague UNCCD (1994, p. 4) definition of desertification: ‘‘Land degradation in arid, semiarid and dry sub-humid areas resulting from various factors, including climatic variations and human activities’’. Most respondents’ perceptions stemmed from the climatic scarcity of water as the main characteristic of the problem. As 5.NAd1 remarked, ‘‘aridity is frequently confounded with desertification’’. Emphasis on the lack of water due to climatic conditions, and consequent natural loss of vegetation cover, soil erosion, and loss of productivity, was particularly reflected in the responses from farmers’ organisations representatives (19.OPA2, 20.OPA3, 21.OPA4, 22.OPA5, 23.OPA6). In addition, national administrators related to water management (9.NAd5, 10.NAd6) and irrigation planning (8.NAd4), and regional authorities in the agriculture department (11.RAd1, 12.RAd2, 13.RAd3, 15.RAd5), also fully agreed with this perception. Forming the second category, several respondents emphasised the human causes of desertification. For these interviewees climatic aridity is not itself desertification but a characteristic condition of semi-arid environments. Instead, these respondents (5.NAd1, 16.RAd6, 17.RAd7, 25.NGO2) pointed to the influences of human activities as the main component of desertification, mainly deforestation and inadequate agricultural practices. ARTICLE IN PRESS J.J. Oñate, B. Peco / Land Use Policy 22 (2005) 103–114 Desertification understood as humans deserting the area, agricultural abandonment and/or population loss following fall of land productivity, forms a third category of the problem perception among the respondents (8.NAd4, 14.RAd4, 18.OPA1, 23.OPA6, 26.PC1). The drivers of this fall in land productivity were seen to be both aridity and market conditions, and the problem was invariably located in the nowadays economically non-profitable dry lands. As respondent 18.OPA1 put it ‘‘if there is no farmer activity, desertification increases’’. A fourth category of respondents stressed the need to actualise the concept of desertification in order to focus attention on the unsustainable management of water resources, which they regard as the main component of actual desertification processes. Overgrazing, deforestation and inadequate agricultural practices were all considered causes of past erosion in the hills. Instead, these respondents (2.Ac2, 24.NGO1) identified irrational overexploitation of aquifers, due to irrigation expansion, as the main driving force of the current erosion and salinisation problems. Respondent 2.Ac2 pointed out the difficulty of recognising problems, which, like desertification, are based on value judgements: ‘‘loss of productivity accompanies desertification for those interested in biological production (fixed carbon/m2), but from the economic point of view even a degraded soil may be quite profitable if inputs of matter and energy are provided’’. Finally, a fifth category understood desertification as a global process of environmental degradation, with both natural and human drivers, and multiple spatial expressions, ‘‘resulting from the rupture of the equilibrium between natural resources and socio-economic systems’’ as respondent 3.Ac3 expressed it. Academics (1.Ac1, 3.Ac3, 4.Ac4) and two national administrators (6.NAd2, 7.NAd3) supported this view. Relationships between in-migrant workforce and natural residents and their role in development were considered as well as contemporary expressions of the global process by respondent 1.Ac1. Historical trends of land use change in the area Historical trends and social and technological change affecting the entire Region emerged in the research as the framework for an understanding of contemporary land use changes in the Guadalent!ın. Millenary irrigation cultures existed along the lower river courses, typically limited by technological factors. The remaining territory was only densely occupied in the 18th century, when dry land agriculture expanded into the uplands, causing serious soil erosion and sporadic flood damage in the main lowland cities (Romero-D!ıaz et al., 2002). But the late 19th century railway link 107 between Murcia and the inner Peninsula facilitated the arrival of much more competitive cereal from Castile, triggering an impoverishment of the regional economy and emigration. By that time, ‘Murcia and its farmers were amongst the poorest in the country’ (4.Ac4). Irrigation promotion entered the political arena at the turn of the 20th century, when water become an instrument of social, economic and spatial transformation and the state paid for the costs of the necessary dams and related infrastructure.3 Opportunities arose for individual farmers and job-creating agro-business companies, reversing the emigration trends (Sa! nchez and Ort!ı, 1993), and under the model of the Development Plans of the 1960s (Harrison, 1993), ‘the south-east of the Peninsula was definitely allotted the function of horticulture and fruit production’ (1.Ac1). Consequently, water demands for irrigation increased and the arrival of submersible pumps initiated the ‘mining of groundwater resources’ (5.NAd1). The ‘off-site implications of the new model’ (7.NAd3) became evident with the construction of the Tagus– Segura transfer channel in the mid-1970s. The channel brought water from the centre of the country, contributing to the expansion of both real and perceived water availability. Land was ploughed above the designated transfer height (200 m), following the reasoning ‘we’ll first plough and then we will be given water’ (3.Ac3). However, an intense drought in the late 1970s revealed that the design parameters for the channel had set unrealistic expectations of water surplus in the donor ! ! basin (Lopez-Berm udez et al., 2002). As a consequence, Murcia never received the expected yearly 900 Hm3 of water, and the water deficit become structural in the basin (CHS, 2001). As of the dry lands, the highest erosion rates were probably reached in the 1940s, when cereal growing was promoted even at the expense of forest areas (Barbera! et al., 1997). Further changes continued in the 1960s when the esparto (Stipa tenacissima, a native grass species used traditionally in wickerwork) became useless with the appearance of plastic. Almonds, carobs and figs were planted in esparto areas, many slopes ploughed vertically when tractors became available. Severe floods and their effects on lowland settlements made the situation worse and preventive forestation measures were implemented in the uplands during the 1950s. Aggressive methods such as terracing with heavy machinery and conifer plantations were widely introduced, clearly out of place in most cases (Chaparro and Esteve, 1995): ‘Those policies mostly worsened many of the existent problems’ (5.NAd1). 3 The lack of consideration for the environmental dimensions of water completes the axes of the so-called ‘water paradigm’ (Saur!ı and Del Moral, 2001), which has determined Spanish water policy ever since. ARTICLE IN PRESS 108 J.J. Oñate, B. Peco / Land Use Policy 22 (2005) 103–114 Decline of dry land crops and orchards and expansion of horticulture and fruit growing were exacerbated by new market opportunities for irrigation products after 1970. The preferential agreement with the EEC facilitated access to and demand from the international market, which opened completely on Spain’s accession in 1986 and the Single Market in 1992 (Pe! rez Yruela, 1995).4 As one respondent argued, ‘business dynamics in agriculture ran ahead of the process’ (4.Ac4), and not surprisingly, government support for irrigation increased in the form of infrastructure construction and farm subsidies. Attention was diverted away from dry lands and cereals declined further with the late 1970s drought. The consequent abandonment of traditional soil conservation techniques accelerated the ongoing erosion problems (Cerda! , 1997), although in some areas a slow but constant process of shrub vegetation recovery was also reported (Obando, 2002). Logically, the water deficit in the basin has also kept increasing (CHS, 2001),5 despite part of each new water input being theoretically allocated to deficit avoidance. Irrigation technology has been geared to serve this expansion, since ‘every drop of saved water is used in subsequent irrigation expansion and yields increased productivity’ (24.NGO1). As a result, in less than two generations farmers have returned from forced emigration to industrial centres in Barcelona and Madrid to live in the region with one of the highest growth rates of agricultural productivity in the country (CESRM, 1997). This clear enhancement of people’s economic standards has led to a social momentum in favour of irrigation at the expense of dry land farming. Several interviewees used the Latin expression, ‘animus regandi’: ‘People irrigate because it is part of their culture’ (9.NAd5). Further, irrigation has recently acquired surprising functions in peoples’ perceptions based on the assumed equations of water= irrigation, drought=desertification: ‘Irrigation is a constraint on the advance of the desert’ (20.OPA3) or ‘In this Region they say that the desert begins where lettuces end’ (9.NAd5). Contemporary policies and ultimate effects—the policy impacts Irrigation expansion Early policies underlying irrigation expansion culminated in the construction of the Tagus–Segura transfer 4 Volume of vegetable exports doubled between 1986 and 1996, representing in the latter 47.5% of the entire Murcian foreign trade (INE, 2000), Germany, the United Kingdom, France and The Netherlands being the destination of 84% of horticulture foreign trade (CESRM, 1997). 5 ‘It is now officially estimated to be 460 Hm3, although considering illegal overexploitation, it may reach 800 Hm3’ (9.NAd4). channel in the late 1970s (CHS, 2001), when most permits for running water were also allocated. Since demand by the transformed areas exceeded the water actually transferred, ‘Groundwater extractions were begun provisionally (for 2 years) in expectation of further transfers that did not arrive’ (8.NAd4). Constant groundwater exploitation began, and enhanced technology enabled wells to be drilled deeper. The 1985 Water Act legalised most groundwater pumps and instituted a permit system, but could not inhibit their illegal spread: ‘The Water Act reached Murcia 20 years too late, when most wells were already operating’ (12.RAd2). As irrigation business grew, an unregulated water market arose, with permit owners illegally selling part of the water they were allocated but did not use. ‘The mobility of water all across the Region hinders control over its legal origin, and the CHS just sits and watches what happens’ (24.NGO1). After Spain’s entry into the EEC, structural aid for farm modernisation (under Regulations EEC/797/85, EEC/ 2328/91, EC/950/97, EC/1257/99) promoted increased productivity and indirectly, irrigation expansion. Now with full powers in agriculture and environment, ‘The Region defended its farmers by consolidating irrigation just to worsen the deficit and force new water transfers’ (8.NAd4). Regional administrators argue that they were only pursuing water use efficiency but ‘did not have power over water management’ (13.RAd3). CHS respondents complain that they did not have enough staff to cope with the Water Act provisions, which ‘was an excessive responsibility for this body’ (9.NAd5). Academics believe that, ‘Delegation of responsibility by CHS to other actors is an historic phenomenon: they did let it happen’ (2.Ac2). Conversely, EU accession did not serve to limit or control irrigation expansion since the Common Agricultural Policy (CAP) has never covered horticulture production. Farmers’ vision, in turn, still demands more support to irrigation agriculture from public authorities, particularly for small and medium sized holdings. When surface waters became scarce and in order to afford investments made to introduce irrigation, they ‘were obliged to extract groundwater’ (20.OPA3), and ‘thanks to that we have survived’ (19.OPA2). They complain that the regional agriculture administration and the CHS have not co-ordinated efforts in order to manage the dynamics of irrigation expansion, and that they have favoured big companies of industrial agribusiness to the neglect of the small farmer: ‘Big producers are the ones who really control the situation: water, market, investments’ (18.OPA1). Anyhow, irrigation is seen as the only development possibility for them, so they keep on demanding water, although some of them recognise that ‘the legacy to our children is going to be a disaster’ (23.OPA6). The 1999 Water Act prohibited new wells but could not reverse the trend. As in the rest of Spain ARTICLE IN PRESS J.J. Oñate, B. Peco / Land Use Policy 22 (2005) 103–114 (Sumpsi, 2001), rural policy design and implementation (e.g. Reg. 1257/99/EEC) is still dominated by a ‘productivist’ ethos, in which ‘Agriculture and water policies are combined to modernise and improve the competitiveness of irrigation’ (11.RAd1). All respondents agree that aquifer overexploitation is ! ! an effect of irrigation (see also Lopez-Berm udez et al., 2002; and Lemon et al., 1994 reporting the same effect in the Greek Argolid), but legally prescribed restoration plans have not been put into practice ‘due to lack of collaboration from users’ (10.NAd6). Irrigation with extracted saline water is lowering production due to soil salinisation in many places (Pe! rez-Sirvent et al., 2003), especially in the Guadalent!ın, where ‘The situation has reached a limit in fruit orchards’ (20.OPA3). Water table depletion has dried up natural wells and wetlands, also widely acknowledged although some argued that ‘The drying of natural wells is due to the lack of rainfall; if it rained they would recover’ (16.RAd6). Impact on valuable fauna and flora has been evident in the case of the Saladares del Guadalent!ın wetland, where ‘Water used to rise to the surface, but they are now dry and partially ploughed in spite of being a protected area’ (15.RAd5). Another symptom of water overexploitation has been the lowering of river flow rates and the inability to dilute sewage from the growing population.6 As newspapers state, ‘The Segura River is a sewer’ (El Pa!ıs, 1999). In spite of being responsible for sewage control and water treatment, the Region has only recently started to tackle the problem, and ‘Works cannot be finished overnight’ (11.RAd1). Besides expansion, specialisation and intensification of irrigated agriculture have undeniably taken place in the area,7 with associated land degradation effects such as diffuse pollution. However, provisions under the Nitrate Directive (676/91/EEC) have not been implemented (Izcara Palacios, 1998): ‘To live is to pollute and with an intensive activity like irrigation it is obvious that you must enter into conflict with the environment’ (14.RAd4). Changes in dry land areas In the early 1980s, and with CAP subsidies in mind (e.g. EEC Reg. 2727/75, 466/82 and 797/85), surviving 6 According to the 2001 census, regional population has increased 25.03% since 1981, more than three-fold the national figure of 8.21% (INE, 2002). 7 Intensification is reflected in the 1993 figures for the quotient between Standard Gross Margin and Utilised Agricultural Area, which was 944.2 h/ha, and for that between Gross Margin and Annual Labour Unit, which was 11,133 h/ALU, two-fold and three-fold, respectively, the national figures (CESRM, 1997). Horticulture and fruit growing represented, in the same year, 62% of the total agricultural production of the region, reflecting a much higher specialisation than in the rest of the country (28%, CESRM, 1997). 109 cereal crops as well as traditional almond plantations were extended at the expense of recovering scrublands, without conservation practices or soil care. ‘Given the public and indirect benefits the government should have resolved the situation by taking the Mediterranean forest domain out of private hands,’ (5.NAd1). After 1986, the CAP clearly helped to expand and intensify dry land agriculture in the hills, with renewed ploughing-up of abandoned zones, ‘A forbidden but almost impossible to control practice; no one in Europe has controlled it’ (13.RAd3). Following the area payments for cereals, almond subsidies (e.g. Reg. EEC/1035/72 and EC/2000/96) were particularly harmful for erosion (van Wesemael et al., 2003), with new orchards planted after surface levelling with machinery. Agriculture administrators now acknowledge the negative effects of destroying terracing but, ‘Agricultural policies and thus the government focused exclusively on profitability. The environment was scarcely mentioned in the CAP until Agenda 2000’ (13.RAd3). Positive effects of CAP regulations were also mentioned in the interviews, particularly concerning setaside (Reg. EEC/1094/88), which in some locations ‘facilitate the natural recovery of protective vegetation and reduce previous erosion’ (16.RAd6). Nevertheless, set-aside was also claimed to have been a driver of erosion, especially in places where farmers were still undertaking soil protection techniques. ‘The Government should be more careful in selecting areas to implement these policies’ (3.Ac3). In any case, the extent of current erosion problems caused by dry land agriculture appears to be much smaller than those caused by the uncontrolled irrigated invasion of hilly areas (Barbera! et al., 1997). Thanks to the technical mobility of water, ‘Many farmers who own both irrigated and dry land just move their irrigation to less exhausted or salty soils’ (12.RAd2). Further, agribusiness companies have bought low-priced dry land, invested in pumping their water allocations, eliminated erosion-preventing structures such as terraces, and installed irrigated groves, ‘Greenhouses having even been seen in the mountains’ (13.RAd3). Heavy machinery can easily work the highly mouldable metamorphic and sedimentary rock to create a levelled surface which, despite the lack of soil, has enough fine particles to feed the crop, ‘Agriculture is no longer linked to soil, which just acts as a physical base’ (9.NAd5). After the water supply ends or the soils become too salty for horticulture, the transformed plots are usually either reconverted into dry land or directly abandoned. As a result of the loss of soil conservation techniques, ‘The erosion hazard may become even greater than before the changes’ (13.RAd3). Lastly, perhaps the most far-reaching effects of irrigation expansion in the area, at least in human ARTICLE IN PRESS 110 J.J. Oñate, B. Peco / Land Use Policy 22 (2005) 103–114 terms, have been on social awareness and culture in the dry lands. In this sense, human, technical and economical resources focussing on the problems and demands of dry land areas have been kept to a minimum in comparison to those targeting irrigation. As one agriculture official put it, ‘Contact with dry land farmers is minimal, and is only done to monitor the received subsidies’ (15.RAd5). CAP and the EU were criticised for not being sensitive enough to the problems of southern European countries, as ‘These problems are not understood by those who have not suffered from them’ (12.RAd2). As a result, locals have seen how the legacy of their ancestors has become undervalued in economic terms and government consideration, and in the absence of social recognition, ‘Frustrated farmers tend to refuse the role of ‘nature guardians’ foreseen in CAP reform orientations’ (4.NAd4). In this situation, farmers’ management decisions tend to be more drastic, seeking the most rewarding subsidy regardless of good agricultural practices, before being forced to abandon the farm. ‘From a desertification perspective, social change operates in a negative way for dry land farmers and their successors’ (2.Ac2). The role of recent policy instruments Agri-environmental and agri-forestry schemes The first agri-environmental programme (Reg. EEC/ 2078/92) in Murcia (1994–1999) covered nearly 1550 farmers (2.7% of total), 40,000 ha (9.1% of arable area) and roughly h 8.97 million. Unfortunately, a breakdown of figures for the Guadalent!ın area is not available. As in many areas of Spain (Peco et al., 2000), the Regional Agriculture Department blamed the limited implementation of this scheme on budget restrictions, especially since in Murcia, ‘Irrigation is a top priority and agri-environmental measures have more budgetary limits’ (11.RAd1). Passive resistance against the agrienvironmental schemes was also related to the conflict they face with predominant ‘productivist’ orientations (Peco et al., 2000) and its high transaction costs, ‘which caused the delay and low level of its implementation’ (7.NAd3). Although these initiatives were considered useful for avoiding erosion and reducing agro-chemical usage, many respondents claimed the present CAP does not adequately support them, ‘Payments from these initiatives are quite low’ (19.OPA2). The cereal extensification measure has been the most important in terms of uptake, particularly in the upper part of the basin where around 4000 ha are engaged in the programme, ‘Ploughing along contour-lines is the most rewarding commitment in terms of erosion prevention’ (13.RAd3). The measure for integrated pest control on white grape vineyards has also been important, concentrating most education and training efforts. However, its anti-desertification role seems limited because it is implemented on irrigated land, and the lack of a national regulation on integrated production ‘facilitates the concealment of commercial production under an environmental facade’ (7.NAd3), an opinion shared by environmentalist groups. No figures on the uptake of organic farming were available, but since no detailed requirements concerning good agricultural practices were included in the measure, its impact on desertification is doubtful beyond the positive effects of lower chemical usage. A new agri-environmental programme is available for the 2002–2006 period, including measures for dry land erosion combat, cereal extensification, organic farming, integrated pest control and education and training. The number of applications (approximately 5000 farmers) has surpassed expectations and all measures include a compulsory code of good agricultural practice. The programme design, particularly the integrated control measure, was nevertheless thought to have insufficient details since, ‘The technical complexity of these issues is not appropriately reflected in the commitments because the government lacks sufficient technical support’ (13.RAd3). For academics, anti-desertification measures should be targeted much more at specific areas, given the spatial diversification of existing problems and ! ! opportunities (Lopez-Berm udez et al., 1997), ‘a matter of sensitivity and technical capacity’ (2.Ac2). The agri-forestry scheme (Reg. EEC/2080/92) suffered from scarce budget allocation even in comparison to the agri-environmental package, in spite of the perception that it is ‘highly positive in terms of retiring low-productive, intermittently cultivated dry lands and a common source of desertification’ (12.RAd2). Only approximately 10,000 ha have been planted in the entire Region (Guadalent!ın data unavailable). Nevertheless, this scheme was also criticised because of design deficiencies, ‘It just promotes tree plantations with a view to productivity, which is ridiculous in a semiarid climate’ (24.NGO1). Furthermore, ‘It is creating a mosaic of unconnected forested patches with a dubious environmental outcome’ (7.NAd3). Altogether, the so-called ‘subsidy culture’ was raised as a threat concerning desertification, especially in the case of the foreseen reduction or even complete abandonment of the subsidy regime by 2006–2008, ‘farmers accustomed to subsidies might abandon soil conservation practices, which for better or worse, they are performing today’ (3.Ac3). This is a vision unfortunately confirmed by one respondent from a farmers’ organisation: ‘they go into these schemes because it helps in monetary terms not so much because of principles’ (19.OPA2). Modulation or cross-compliance of direct payments were seen as possible financial sources to overcome the ARTICLE IN PRESS J.J. Oñate, B. Peco / Land Use Policy 22 (2005) 103–114 budgetary restrictions on these schemes. However, its applicability in Murcia was said to be low, ‘because there are not that many big holdings’ (13.RAd3) and ‘due to lack of political will’ (7.NAd3). Hydrological corrective measures and forestry measures As in the rest of Spain, these have been the only publicly financed erosion initiatives, with two types of instruments usually implemented on public land (Rojo Serrano, 1998). First, water authorities design and execute projects for the hydrological correction of creeks and protective forestation in order to prevent dams filling with sediments. Second, forest services implement forestation measures, under ‘protective’ or ‘productive’ aim depending of the location. Both have benefited from the EAGGF-Section Guidance and the Cohesion Funds after accession to the EU. Methods and techniques have been criticised regardless of the instrument and the Government concerned (e.g. Garc!ıa Pe! rez and Groome, 2000), as the quantity of the forested area rather than quality of the restored ecosystem is usually the main objective. The Guadalent!ın is not an exception, and examples of counterproductive actions (e.g. aggressive terracing methods, planting of inadequate species and lack of site-targeted design) abound, since ‘A standard model has been implemented regardless of site-specific conditions’ (4.Ac4). In spite of the general experience, examples of good erosion control results were also mentioned, and community memory of flood damage in the area explains why locals generally perceive these measures as having positive effects on desertification. There has been no official systematic monitoring of their effects on erosion rates, and the number of afforested hectares is the only indicator of effectiveness (Chaparro, 1994). More interest was expressed in bolstering instruments to subsidise measures in private forests (58% of regional wooded surface, CAAMA, 2001), since ‘due to low productivity owners do not take care of forests, leading to a greater fire hazard’ (16.RAd6). Although instruments serving these ends have been in place for a long time (e.g. Reg. EEC/1610/89) and they are considered to be ‘Adequate tools to fight desertification’ (6.NAd2), budget cuts have prevented their wider implementation, ‘Forestation of marginal or abandoned agricultural land, managed by the Agriculture Department has taken the lion’s share’ (16.RAd6). Land use planning and related policies Paradoxically, the expansion of intensive irrigation is forbidden since 1986, when the first Regional land use planning legislation was issued. Subsequent hydrological planning documents confirm this limitation. In reality, however, it seems obvious that ‘Physical 111 planning has been subsumed to the logic of irrigation expansion’ (1.Ac1). Many respondents doubt whether these policies could have stopped or re-oriented irrigation expansion: ‘There is no way to resist such powerful social and economic pressure’ (17.RAd7, 2.Ac2). In Spain, land use planning policies have traditionally focused exclusively on the territorial location of economic activity and necessary infrastructure arrangements (Oñate et al., 2002a). This approach partly explains why the total area of protected land in the Region was reduced by near 11,000 ha in 2001, mainly around areas of agricultural and/or tourist interest (La ! 2001). Related legislation on nature conservaOpinion, tion, for example, has not prevented the perfectly visible invasion of protected areas by expanding irrigation, a process denied by respondents from the Regional Government, ‘Non-agrarian zones have not been affected’ (16.RAD6), belittled, ‘Invasions are not overall significant’ (12.RAd2), or justified, ‘Levelling is a benefit, not an erosion problem because it compacts the soil’ (15.RAd5). Although planning documents (MIMAM, 2001a; CHS, 2001; MAPA, 2002) mention the need to take environmental considerations into account when implementing irrigation projects, experience shows that this has never been a priority. ‘Impact mitigation measures should have been implemented before, to preserve particular locations of outstanding natural interest, avoiding landscape simplification, and maintain native vegetation strips to enhance connectivity between natural habitats’ (2.Ac2). In the absence of legislation prescribing environmental assessment at the strategic levels of plans or programmes (Oñate et al., 2002b), impact assessment at the project level has proved unable to control irrigation expansion and ameliorate its subsequent effects, ‘in spite of legislation that prescribes it for every transformation’ (25.PC1). Unfortunately, in February 2004 Spain is the only northern Mediterranean country that has not delivered to the UNCCD its National Action Plan to Combat Desertification (NAPCD), and only a working draft was made available in 2001 (MIMAM, 2001b). Significantly only seven out of the 25 interviewees acknowledged familiarity with the draft NAPCD, eight had heard about it but were not aware of details, while the remaining 10 were unaware of its existence. In the light of this poor result at the local level, it seems fully justified the appreciation that its design process, ‘lacks communication with society, and many Government Departments disown the plan’, as one of its writers recognised (3.Ac3). However, it is significant that the respondents from the CHS, the Physical Planning Department and four of the representatives of farmers’ organisations were not aware of the NAPCD. The fact that the Plan is co-ordinated nationally by the Ministry of Environment could explain the low interest detected amongst agriculture-related actors. ARTICLE IN PRESS 112 J.J. Oñate, B. Peco / Land Use Policy 22 (2005) 103–114 Further, its coincidence with the passage of other national plans related to the issue such as the Hydrological and Irrigation Plans, was pointed out as evidence of the lack of political will to tackle the root of the problem. ‘Governments attach much more importance to other issues, while desertification is politically unprofitable’ (6.NAd2). Conclusions The stakeholder interviews in the Guadalent!ın basin illustrated the clear impacts of past policies on land degradation, reflecting that desertification, as an environmental issue, has suffered from the so-called ‘Mediterranean syndrome’ (e.g. La Spina and Sciortino, 1993), which makes the promotion of non-economic interests rare or at least difficult at a local level. The different dynamics followed in irrigated and dry land areas require a separate re-orientation of anti-desertification policies in each area. Current social, economic and institutional attention is clearly focussed on the new prospects of water transfer foreseen in the recently passed NHP. Experts have argued that solutions to the structural water deficit in the basin have been tackled from the supply side rather than from the demand side (e.g. Sumpsi et al., 1998). Although no new expansions of the irrigated area are officially foreseen for the Region, further irrigation expansion can be expected due to economic reasons. Considering that the marginal value of water allocated to conversion of dry land into irrigation is at least three times that of water allocated to precarious irrigation consolidation,8 the most rational economic behaviour by farmers is to further expand their irrigated land. Therefore, established control mechanisms in the NHP to police the destination of transferred water are in risk to be as useless as those included in previous regulations. Even the full implementation of the EU Water Framework Directive, which establishes the integral recovery of investment and maintenance costs of new infrastructures, does not seem capable of deterring this unsustainable expansion (Escart!ın and Santafe! , 2001). The marginal productivity of water for this type of intensive irrigation is 0.3–0.6 h/m3, and even higher in greenhouse farming (MAPA, 2002), still enough to compensate for the future cost of transferred NHP water, estimated to be roughly 0.31 h/m3. Even if the large transfer infrastructure envisaged in the NHP were not built,9 irrigation expansion has the potential 8 According to figures from the own NHP, estimations for the marginal value of water range between 0.18–0.36 h/m3 in the former case and 0.054 h/m3 in the latter (MIMAM, 2001a). 9 This is a plausible possibility due to the protests against the transfer in donor regions and to the doubts about EU co-financing (total cost is estimated at present at more than 4 billion h). to continue. Desalinated seawater currently costs around 0.42–0.48 h/m3, but future technological developments will probably lower this to figures perfectly affordable by intensive irrigation farmers (Sumpsi et al., 1998). Therefore, neither water prices, which in this case do not serve to regulate water demand, nor CAP regulations, which do not cover this type of production, will be able to control irrigation expansion. In policy terms, only strict environmental policy enforcement to tackle the negative on- and off-site impact can bring the situation under control, although the economic and political costs of this option will clearly be high. The only other restraint to water demand and irrigation expansion comes from the market side. Although only foreseeable in the longer term in the context of further international trade liberalisation, a possible saturation of European fresh vegetable and fruits markets could be expected following increased imports from third countries (e.g. Morocco). The possibility of addressing desertification in dry land areas through policies seems much more feasible, simply because expectations of economic results are much lower than on irrigated land. Current policies, mainly EU driven, have played a contradictory two-fold role, simultaneously promoting agricultural set-aside and land use intensification, while erosion mitigation has never been an objective of the agricultural subsidies. However, clearer options to focus policies on desertification are now starting to appear at present. The new agri-environmental schemes begun in 2002 are the closest positive example. In addition, public forest management schemes and forestry measures on private land could be implemented in the near future under the recent Regional Forest Strategy. Most importantly, the medium-term CAP review could free more budget resources to empower these socially and institutionally feasible options.
