Über dieses Buch

Mediterranean irrigation is diverse due to, among other factors, the relative importance of water in the economy of each country, varied levels of aridity, heterogeneous levels economic, social and technological levels of development, and differences in political and social organization. However, most of the Mediterranean countries face similar problems to meet their water demands because of the scarcity and variability of renewable resources, growing water requirements from non-agricultural sectors, increasing environmental concerns related to water quality and environmental degradation, a social demand for larger public participation, and important technological changes. The time has come to reconsider the “not one drop lost to the sea” philosophy of yesteryears largely and to 'live within limits'.
This book focuses on eight selected countries (Tunisia, Morocco, Spain, France, Italy, Turkey, Israel and Egypt) and provides a comparative perspective that both thoroughly explores their specificities and identifies the common challenges faced by the irrigation sector in these countries. The book has been written at a critical moment, when the continued application of a supply-side water management model is revealing its unsustainable nature in numerous places; when significant technological changes are taking place in the irrigation sector; when new forms of management and governance are widely held as badly needed; and finally, when climate change is compounding many of the difficulties that have characterized irrigation policies and practices in the past decades.
This complicated future context makes Mediterranean irrigation face various political dilemmas on water management, raising social tensions, triggering territorial and land conflicts, and stimulating new technological developments. This book provides a timely analysis of the particular trajectory of eight Mediterranean countries in these uncertain transformations, and attempts to identify the best strategies to avert or overcome future risks.

Chapter 1. Introduction
Abstract
This chapter presents an introductory description of political, technological and institutional change in the field of irrigated agriculture in the Mediterranean area. After a brief description of the main characteristics of irrigation in this world region, the chapter introduces the eight national chapters: the cases of Tunisia and Morocco in the Maghreb; Spain, France and Italy in the European Union; and Turkey, Israel and Egypt on the oriental shores of the Mediterranean Sea.

Chapter 2. Tunisia
Abstract
Tunisia is structurally affected by water scarcity and irrigation practices are profoundly marked by the culture and history of the Mediterranean and desert areas. Since 1956, the new Tunisian state has mobilized the financial resources necessary for the development of major public water projects. It also encouraged farmers to develop individual irrigation projects. Despite the relatively limited extension of irrigated areas, irrigation is considered as a strategic sector (food security, economic and social role).
In Tunisia, total water withdrawals are close to the potential of the resource. A “weak form of water demand management” prevails, characterized by the implementation of technical, economic, and regulatory instruments primarily aimed at reducing water losses and inadequate water use and encouraging the use of nonconventional water resources. Weaknesses in agricultural development are found in the majority of large-scale irrigated schemes, where agricultural intensification and the productivity of water remain to be enhanced.

Chapter 3. Morocco
Abstract
Morocco has well developed irrigation facilities that range from small scale communal systems based on springs, qanats or river diversions to groundwater-based individual initiatives and large scale public schemes. Water demand policies – e.g. water pricing, shift to drip irrigation, ‘aquifer contracts’ and other forms of participatory management – have shown little potential in curbing overexploitation of resources in many basins. Expansion of irrigated areas and the priority given to productivity have taken their toll on the environment, favored commercial agriculture, and contributed to a net depletion of groundwater estimated at 1 billion m3/year. There is a need to better align agricultural development, water conservation, and environmental objectives.
After a short historical perspective, this chapter first reviews a number of trends in the irrigation sector (modernization, development of groundwater resources, wastewater reuse and desalination), before turning to regulatory and institutional issues, including participatory management, economic tools, privatization and an examination of the Plan Maroc Vert. The threats posed by climate change, water scarcity, and environmental degradation are then discussed.

Chapter 4. Spain
Abstract
The persistent application of a supply-side management model has led Spain to a critical situation, placing irrigation at the center of national political debates. This chapter describes how, to overcome this hydro-political crisis, the administration and the farmers’ associations have supported three non-conflicting strategies: introducing water markets to give flexibility to the allocation of water for irrigation, stimulating treated wastewater reuse, and modernizing irrigation systems, particularly through the massive transformation of gravity schemes into drip irrigation. This chapter analyzes these strategies and also provides a critical view on groundwater development for irrigation. Finally, agricultural and environmental policy debates and the expected impact of climate change on the irrigation sector are considered.

Chapter 5. France
Abstract
The development of irrigation in France is several centuries old. During the twentieth century the state constructed most of the irrigation networks. Individual irrigation development dates back to the 1960s and is characterized by an easier uptake of technological innovations. Today, the total equipped area is leveling off, and trends include a development of drip irrigation and the near disappearance of gravity irrigation. Public policies with a direct or indirect impact on irrigation have also changed significantly in recent decades. Agricultural policies, once very favorable to the development of irrigation, have moved to policies that are increasingly oriented toward the protection of water resources. In some basins, farmers face severe administrative reduction of their pumping authorization. Water resources management at the watershed or territory levels also changed significantly. In basins facing large quantitative deficits, special institutions are created to manage the volume of water available for agriculture. However, concerns remain regarding the effectiveness of such institutions and more generally the future of irrigation in a context of global change.

Chapter 6. Italy
Abstract
This chapter analyzes the recent evolution and current situation of the Italian irrigation sector, which presents a remarkable dualism between the north and south of the country. After a brief review of the historical origins of irrigation, the chapter examines the role of the state in the regulation and promotion of irrigation in modern Italy since unification. The chapter describes collective irrigation institutions and analyzes the role of the public sector, highlighting the lack of an authority capable of mediating conflicts between the regions involved in water transfers. It also explores the turn toward demand-side management, through an analysis of legislative changes. The last section identifies the main actual and future challenges: the incapacity of current institutions to control groundwater overexploitation, increasing salinization, and the expected impacts of climatic change.

Chapter 7. Turkey
Abstract
This chapter reviews irrigation development and policy with specific references to the main water- and land-based regional socioeconomic development projects in Turkey. It analyzes the expansion of irrigation investment as well as institutional and technological changes in irrigation policy and development in parallel with policies of liberalization and decentralization in the late 1980s. The chapter also discusses institutional changes in the management of the irrigation systems as a result of (partial) transfer of management of large-scale irrigation systems to a variety of water user organizations. Finally, it describes current technological and institutional problems and the further challenges to the irrigation sector, such as infrastructure deterioration, risks of drought, environmental and ecological system degradation, and insufficient investment. It also notes the efforts to equip new irrigation schemes with modern technology, such as closed pipes for conveying water instead of open channels, and water-saving micro-irrigation methods rather than surface irrigation techniques.

Chapter 8. Israel
Abstract
Israel has succeeded in advancing irrigated agriculture on a wide scale on arid and semiarid lands, with an intensive use of technology and capital, and a firm state-led irrigation policy. This chapter describes the evolution of the Israeli irrigation sector since the British Mandate period, distinguishing four distinct eras linked to contrasting political and technological frameworks. It also explores the changes in the institutional framework of the irrigation sector (from the local community level to the state structure). The chapter underscores the critical role of technology in Israeli irrigation, most particularly in the development of micro-irrigation and monitoring systems, and the shift towards desalination and wastewater use for irrigation. Finally, it identifies the major challenges to be overcome, considering water quantity and quality problems, and the impact of climate change, possibly compounded by tensions with neighboring countries.

Chapter 9. Egypt
Abstract
In no other country, perhaps, is the identification between water, irrigation, and agriculture as strong as in Egypt. Several phases of agrarian and technical change throughout its long history have taken Egypt to a situation where farmers grow between one to three crops a year on 3.78 million ha after lifting water from canals and drains, and sometimes from aquifers. This chapter first reviews the extraordinary cost of maintaining the delta ‘irrigation machine’, the history of irrigated agriculture expansion, and the evolution of public policies. It then examines key issues and challenges, including irrigation modernization, the search for water savings, the multiple experiences with participatory management at various scales, inter-sectoral integration, the water-food-energy nexus, the recent masterplan, and finally transboundary threats.

Chapter 10. Irrigation Policies in the Mediterranean: Trends and Challenges
Abstract
Irrigation is a central feature of agriculture in Mediterranean countries. During the twentieth century, and more specifically after World War II, most states have invested massively in large-scale dams, interbasin transfers, and public irrigation schemes. More recently, farmers have capitalized on increasingly cheap pumping devices to tap groundwater, whether in conjunction with surface water or not, and the introduction of pressurized networks has come to constitute a major technological change in the region. This chapter first reviews the changing relationships between irrigation and the wider water sector as scarcity builds up, and ponders on the respective prospects for both supply- and demand-management options. It then takes stocks on recent technical and institutional changes in the irrigation sector before turning to the importance of economic dimensions and context. Finally irrigation is analyzed in terms of policy and political process, and of its relationship with other sectors, while the final section explores the challenges posed by water overexploitation, environmental degradation and climate change.
