ABSTRACT
Since the last five years, European Commission has strengthened the links between environmental and
agricultural policies. This trend benefits terraced Mediterranean landscapes, which maintenance has clearly emphasized
by different Commission reports. But, although European Commission is enhancing the High Nature Value Farmland
and signing Agri-Environmental contracts with farmers, these policies don’t include budget to support the high cost of
maintaining soil and water conservation structures.
On the other hand, despite the big effort performed by European Commission, and other institutions, to revalue
the rural landscape during the last decades, specially through the Convention for the Protection of the Architectural
Heritage of Europe, the Charter of Cracow, the Cork Declaration, the European Landscape Convention, the Council of
Europe’s Cultural Heritage Committee, or the UNESCO World Heritage, day-to-day reality shows that semi-arid
Mediterranean landscapes are losing part of their historical patrimony concerning traditional soil and water conservation
constructions.
In order to integrate all the agricultural system features, the Rural Development Programmes 2007-2013 could
be the proper way to approach the full concept of environment, including the Environmental-Agri-Cultural paradigm.
Recognising in this term that appropriate farming management, and adequate subsidies, have to contribute both to
environmental health and to preserve farming cultural heritage.
We could not forget that besides their support to maintain our rich semi-natural landscapes, farmers have also
to pay a high additional cost to preserve the architectonical pieces of the farming history: stone-walls, water-mines,
houses and associated constructions like laundries, stockyards, etc, in many cases older than 300 years.
This paper presents an overview of the current European Commission policy in order to evaluate facilities
provided by the Commission to terraced landscapes and associated structures.
Introduction
Historically, semi-arid Mediterranean areas were interpreted in accordance with the benefits land supplied to
human being. In this sense, the productive soil-function was valued by its capacity of securing food, grazing, vegetal
and hunting species, or as source of raw materials. This productive vision reached its maximum expression with the
demographic growth of the XVIII and XIX centuries. This was very well resumed by the eighteenth century botanical
Cavanilles, when describing the Valencian Community (Spain) landscape1:
Son secano regularmente los terrenos altos y desiguales, y las faldas de los montes; pero están tan bien
plantados de árboles, que figuran espesos bosques en freqüentes masas de algarrobos, olivos, higueras y viñedo
[Frequently, high and uneven lands are drylands, and the foot of the mountain; but they are so well covered by
trees, that seem dense woods in frequent carob, olive, fig trees and vineyard masses].
This concept predominated in semi-arid Mediterranean countries until recently when new economic structures,
focused on the secondary and tertiary sectors, have reoriented the previous agro-forest soils to other soil functions. The
profitability of one hectare of dryland devoted to industrial or tourist structures or to rainfed agriculture immediately
tips the balance in favour of the two first options, if only considering the amount of labour generated or the net benefit
obtained. Besides these pressures, Mediterranean agriculture has to be competitive through diversifying production,
raising quality and improving water supplies, and to be prepared to the agricultural trade liberalisation, in the context of
the Euro-Mediterranean free-trade area planned for 20102.
The main threat of this economicist soil-function concept is its impact on the environment.
To balance the scales, the European Commission tries to integrate the environmental approach into all
Community policies, ensuring their contribution to the sustainable development 3, and considering that farmland areas

include, further than agricultural productions, other public goods such as the maintenance of the landscape and
biodiversity4.
Specifically, the Commission has designed agri-environmental measures addressed to encourage farmers to
protect the environment on their farmland. These measures, included in the Rural Development Programmes 5 and in the
Biodiversity Action Plan for Agriculture 6, enhance the environmental risk linked to land abandonment, and the
importance of maintaining soil conservation structures like terraces and hedgerows (with particular flora and fauna
habitats). This programme provides incentives to farmers working in accordance with the national codes of Good
Farming Practices, as compensation for extra costs or loss of income.
However, more effort in diffusion is needed because, in the current period 2000-2006, farmers of
Mediterranean European countries have signed less agri-environmental contracts than those of Central or Northern
countries7.
In the same way, the share of agricultural land under agri-environmental measures is also more important in
these last countries than in the Mediterranean. Variations rank considerably between less than 10% of the total
agricultural area in Spain or Greece, to more than 75% in Austria, Germany or Finland, for the period 2000-2003.
Concerning the share of agri-environmental measures targeted to biodiversity and landscape, the balance goes also in
favour of Central and Northern countries 8. This could be done both to:
- a lack of information,
- the small and medium proprieties, that characterizes the Mediterranean basin. The amount provided by the agrienvironmental measures could not compensate the time spent in filling in the forms. In areas with high
percentage of small properties, the municipal government should be authorized to present a unique contract on
behalf of these farmers.
Besides the preservation of landscapes, and their historical features, included into the commitments of the agrienvironmental schemes, it is also considered the support to Less Favoured Areas to maintain scenic landscapes and
environmentally valuable habitats9. In relation to soils, the Commission is finalizing the Thematic Strategy for Soil
Protection10. This document includes the protection and maintenance of terraced areas as priority ones.
The Environmental-Agri-Cultural links
Rural Development Programmes 2007-2013, the second pillar of the Common Agricultural Policy 11, are the
key tools to provide coordinated support to terraced landscapes 12. The four axis considered are:
- Axis 1: Improving the competitiveness of the agricultural and forestry sector,
- Axis 2: Improving the environment and the countryside,
- Axis 3: The quality of life in rural areas and the diversification of the rural economy,
- Axis 4: Leader
In all of them is possible to include initiatives related to terraced landscapes. And, specifically, Axis 3 will
cover studies and investments associated with maintenance, restoration and upgrading of the cultural heritage such as
the cultural features of villages and the rural landscape.
This Council Regulation also considers the establishment of Local Action Groups, National Rural Networks
and a European Network for Rural Development.
In order to collaborate to implementing the regional policies, and to include the traditional soil and water
conservation systems into the Rural Development Programmes, we have:
- to consider the territory as a unit of analysis,
- to consider at the same level agricultural practices and environment safeguarding,

NEW PARADIGMS IN SEMI-ARID MEDITERRANEAN
TERRACED LANDSCAPES STUDIES
- and to consider that both are an essential part of the cultural heritage, recently defined including all aspects of
the environment resulting from the interaction between people and places through time13.
To work in line with the European Commission policies, studies of semi-arid Mediterranean terraced
landscapes have to integrate these three concepts, recognising the multifunctional character of these areas and linking
them with the new sensibility towards landscape and its history.
We could not forget the importance of the financial support to the agricultural competitiveness and to the
agricultural diversification, but due to the new oriented economicist soil-concept, and to the Northern Mediterranean
countries relief, terraced territories are suffering important impacts and pressures.
One of the main characteristics of rainfed semi-arid Mediterranean areas is land abandonment that could result
in severe impacts on landscape and biodiversity. As recognised by the European Commission there are high nature
value farmland areas under stress due to depopulation or fragile economic situation of farmers 14. In semi-arid
environments, most of these areas are terraced.
Littoral good agricultural soils, in irrigated-terraced areas, are sharing prominence with the pressure of urban
expansion. Meanwhile, the less profitable agricultural ones, without access facilities, have been abandoned since the last
forty years. This abandonment is provoking important effects, as the revegetation of the territory with shrub-like
species, or even the loss of biodiversity provided by the agricultural soils15. In order to prevent risks in abandoned
fields, the European Commission recommends the first afforestation of these areas, with species adapted to the local
environmental conditions16.
The abandonment could cause a significant landscape disorganization, and the deterioration of an impressive
cultural heritage, because these semi-arid terraced areas are usually associated to constructions related to water
catchment, harvesting and distribution, like minas, qanats, fogara, acequias, balsas, cisterns, algibes,… and to rural
buildings, which reconstruction has always to be linked to any landscape intervention.
These are spaces with name and surnames, and it is needed to consider their historical perspective and context,
and highlight their importance in the Rural Development Programmes. In most villages, we could know who organised
and managed the terraced landscapes, and, at least from the XIII century, depending on the zone, we could consult in
the contemporary documents the needs and requirements of rural people: how they built irrigation channels or dams to
improve fertility in the terraced fields (Figures 1, 2, 3), who did the works, how many job or money they had to
contribute, the participation of the feudal lord,..., even who lived in a concrete farm and worked its land. In most cases,
we could also reconstruct, almost year by year, the agrarian initiatives (Figure 4), the irrigation regulations, the new
establishments of lands, the final destinations of the products, the governmental legislation concerning land uses, etc.
Indicators for assessing Environmental-Agri-Cultural measures in terraced landscapes
The European Commission is also developing Indicators for the integration of environmental concerns into the
Common Agricultural Policy17.
ELISA (European Union Concerted Action Project on Environmental Indicators for Sustainable Agriculture)
identifies 22 State indicators and 12 Pressure indicators to measure the impact of agriculture on environment, and to
monitor the effects of existing and future agri-environmental measures18.
LUCAS (Land Use/Cover Area Frame Statistical Survey) objectives are focused on collecting land use and
cover data, and environmental features. It was calculated that linear features, like stone walls, had an estimated length
for European Union15 of 1.612.533 Km [1-3 m width] and 104.921 Km [>3 m width] 19.
EUROSTAT recognises the Indicator Changes in traditional land-use practice, defined as changes in
traditional high value farming practices resulting in homogenisation of land use and loss of habitat and species
diversity, as a Pressure Indicator for the Loss of Biodiversity 20.

One of the IRENA (Indicator Reporting on the Integration of Environmental Concerns into Agricultural
Policy) 21 objectives is the study of structural elements in the landscape. Concerning terraced areas, could be of interest
Indicator number 32 (Landscape State) and 35 (Impact on Landscape Diversity), but recognising limits in the data
sources for studying small size high value landscapes. In this sense it is proposed the use of Member States own
inventories. Indicators directly related terraced landscapes are:
- Driving Forces: Land use change; Cropping patterns;
- Pressures: Farm management practices; Land cover change;
- State: Soil erosion; Soil quality;
- Responses: Area under agri-environmental support; Good farming practices; Area under organic farming.
IRENA Indicators concerning Biodiversity and Landscape are(number):
- Driving Forces: Land use change (12); Marginalisation (17);
- Pressures: Cropping patterns (13); Genetic diversity (25);
- State: High Nature Value farmland areas (26); Landscape state (32);
- Impact: Impact on landscape diversity (35); Impact on habitats and biodiversity (33)
The development of a minimum set of appropriate Indicators of Driving Forces – Pressures – State – Impacts Responses could be a useful tool to assess the contribution of traditional soil and water conservation systems to the
implementation of the agro-environmental European Union policies. As well as to provide quantitative information and
to validate the effectiveness of these measures.
These indicators, addressed mainly to be used as policy decision supporting information, have:
- to identify the characteristics of the traditional soil and water conservation systems that fit with the agrienvironmental European needs,
- to assess the specific contribution of these systems to sustainable agriculture,
- to monitor, in a long-term progress, its environmental contribution at local level,
- to localize the hot spots problems [soil erosion, water needs, vulnerable areas...] due to abandonment,
- to evaluate its presence in the European Union sectoral policies,
- to map the productive and abandoned terraced areas; in use and abandoned traditional water resources; and High
Nature Value Farmlands in which these traditional systems are predominating.
According with a preliminary European landscape classification, most semi-arid Mediterranean terraced
landscapes could be included in the following types 22:
- farming dependent high nature value and cultural landscapes threatened by the marginalisation of agriculture
and where agriculture has a particular role in creating environmental quality,
- landscape characterised by low-input farming, low pollution and resource depletion as well as the enhancement
of habitats and biodiversity,
- landscapes characterised by intensive or extensive good farming practice in a balanced relationship with the land
leading to the maintenance of natural resources, biodiversity and semi-natural ecosystems.
It would be desirable indicators could provide information for these different landscapes, and it could
contribute to assess the environmental services that terraced areas provide to the society. Furthermore, it is very urgent
to quantify and to estimate the hot spots due to land abandonment (Figures 5 and 6), and to drawn maps that could help
the policy-makers to localize the terraced areas at local level (Figure 7).
CONCLUSIONS
In order to provide useful information to policy-makers, terraced landscapes studies have to be addressed in
synergy with the European Commission priorities related to agri-environmental protection and rural development.
Traditional Soil and Water Conservation Systems play an important role in the Mediterranean semi-arid areas,
both at agricultural level –avoiding soil erosion and improving water infiltration- and providing habitat to numerous
species, enriching European biodiversity.
Owing to the new market structures, one of the threats to landscape disorganization is land abandonment. This
process is significantly important in marginal [from the economic point of view] terraced areas. To avoid the negative
impacts of land abandonment, European Commission is enhancing first afforestation of agricultural and non agricultural
land.
At the same level, the rich cultural heritage associated to these areas has to be preserved and revalued. The next
Rural Development Programmes 2007-2013 represent a good opportunity to integrate the management of the terraced
landscape into the agri-environmental measures of the European Union.

NEW PARADIGMS IN SEMI-ARID MEDITERRANEAN
TERRACED LANDSCAPES STUDIES
The development of a set of indicators, identified as appropriated for the semi-arid Mediterranean areas, is
needed to improve the effectiveness of these measures and to quantify their effects on the landscape quality and
diversity.
The integration of all the results in the Traditional Knowledge World Bank will provide precise information on
the state-of-the-art in terraced landscapes studies.
