Technical Report
Full-text available
We review recent literature on participatory scenario development and analysis within the context of ecosystem services (ESS) and biodiversity research. Beyond direct use for AQUACROSS, this deliverable exemplifies how ecosystem-based management (EBM) in aquatic ecosystems can be supported by participatory scenarios. Following the AQUACROSS Asses...
Article
Full-text available
This paper presents a conceptual framework for both assessing the role of economic instruments, and reshaping them in order to enhance their contribution to the goals of managing water scarcity. Water management problems stem from the mismatch between a multitude of individual decisions, on the one hand, and the current and projected status of wate...
Technical Report
A summarized version of AQUACROSS’s Innovative Concept provides a clear and concise overview of the project’s design and strategy for future work. It takes a critical first step to deliver a structured set of ideas and hypotheses aimed at steering the project’s research efforts. The Concept also identifies key strengths and weaknesses of existing a...
Technical Report
Full-text available
The AQUACROSS concept introduced in this deliverable aims to make ecosystem-based management (EBM) an ecosystem-service and resilience-oriented concept that can be made fully operational in the context of the management of aquatic ecosystems (inland, coastal and marine). The AQUACROSS Assessment Framework (AF) will, for the first time, generate con...
Chapter
This final chapter presents the overall balance of collection of cases presented in the whole book. In line with the structure of the book, rather than assessing the EPIs themselves, this analysis focuses on their potential and actual contribution to the goals of water policy as the main criterion to discuss the screening, design and implementation...
Chapter
Water pricing embraces a range of distinct policy instruments that affect the scale and/or the pattern of production and resource-exploitation costs. Ideally, water prices should reflect financial costs of service delivering water infrastructure, environmental costs arising from harm induced to ecosystems and ecosystem services, and resource costs...
Chapter
This first chapter sets the scene for the work presented in this book. Based on a review of the literature, the chapter introduces a definition of economic policy instruments (EPIs) and a classification of broad categories of EPIs relevant for water policy that will be used to present the following parts of the book (prices, trading and other instr...
Article
The large irrigation expansion of the last 50 years has increased pressure on water resources in EU Mediterranean basins. Water charging has been encouraged, since within the EU policy context it is believed that higher charges reduce water use. This paper presents a Revealed Preference Model that provides a clear intuition of the logic behind farm...
Article
In spite of its minor and decreasing share in EU GDP, agriculture still plays a fundamental and strategic role in the economy. This is why EU institutions have supported for decades a series of policies to guarantee a stable agricultural income, including insurance. With different degrees of public support, insurance policies covering an increasing...
Chapter
Rather than setting water prices and leaving quantities to economic agents, water authorities may rather choose to cap water quantity and set the necessary conditions for voluntary trades to happen. From a wider perspective of water use (one not only constrained to water withdrawal and consumption but also to the disposal of polluting substances),...
Chapter
Population and economic growth, coupled with rapid and extensive urban development, pushed to the limit the capacity of the upper and middle stretches of the Tagus River Basin to meet an increasing water demand, within the range of available resources and current water regulation infrastructures. In this context, voluntary agreements to transfer wa...
Chapter
The construction of the Mequinenza and Ribarroja dams back in the 1960s modified the hydrology and changed the physical and environmental conditions of the Lower Ebro River in northeastern Spain. These conditions have stirred the uncontrolled proliferation of macrophytes, which have become a relevant concern in the area since 2000. Among other envi...
Article
A stable agricultural income is often regarded as a way to achieve a better environmental performance in this sector. However, conventional income stabilization tools have been showing recently signs of exhaustion. Under this critical juncture, EU institutions have encouraged the expansion of agricultural insurance. With different degrees of public...
Chapter
Full-text available
Fresh water is a scarce good that is essential for sustaining life, development and the environment and it should be managed accordingly (ICWE 1992). However, water policy has failed to consider water as an economic good and has focused instead on guaranteeing the provision of this resource at subsidized prices. In Southern Europe, this paradigm ha...
Article
Full-text available
Greening the economy is mostly about improving water governance and not only about putting the existing resource saving technical alternatives into practice. Focusing on the second and forgetting the first risks finishing with a highly efficient use of water services at the level of each individual user but with an unsustainable amount of water use...
Article
Full-text available
The Drought Management Plans (DMPs) are regulatory instruments that establish priorities among the different water uses and define more stringent constraints to access to publicly provided water during droughts, especially for non-priority uses such as agriculture. These plans have recently become widespread across EU southern basins. However, in s...
Article
Although the effectiveness of flushing floods in restoring basic environmental functions in highly engineered rivers has been extensively tested, the opportunity cost is still considered to represent an important limitation to putting these actions into practice. In this paper, we present a two-stage method for the assessment of the opportunity cos...
Article
Water is a key input in the production of many goods and services and under certain conditions can become a critical limiting factor with significant impacts on regional development. This is the case of many agricultural European Mediterranean basins, where water deficit during drought events is partially covered by illegal abstractions, mostly fro...

Technical Report
Full-text available
Economic Policy Instruments (EPIs) are incentives designed and implemented with the aim of adapting individual decisions to collectively agreed goals. They include incentive pricing, trading schemes, cooperation (e.g. payment for environmental services or voluntary agreements), and risk management schemes. EPIs may significantly improve an existing...
Article
Recurrent water deficits in various arid and semi-arid Mediterranean basins are largely covered by illegal groundwater abstractions uncontrolled by the water authorities. Aquifers thus play the role of buffer stocks and are used by farmers as a reliable, though informal, insurance system. This has led to continuous groundwater depletion and increas...

Article
In several arid and semi-arid Mediterranean basins, water deficits in irrigated agriculture during drought events are relieved by illegal abstractions from aquifers. Illegal abstractions are largely tolerated by the authorities and are regarded by farmers as a reliable and inexpensive form of insurance against drought. This framework of illegal abs...
Article
Groundwater resources are traditionally overexploited in arid and drought-prone regions with profitable irrigated agriculture, and the depletion of this groundwater results from a combination of the physical scarcity of surface sources and the lack of effective control of use rights on the part of water authorities. This is the case in the Segura R...
Article
Full-text available
This paper develops a general preference model to explain farmers’ decisions. Contrary to better known and most commonly used simulation models, the one presented in this paper allows to calibrate, simulate and explain farmers’ decisions without assuming linear preferences (as in many multi criteria decision models) or unobservable implicit cost fu...
Article
Full-text available
Modern water policy requires new kinds of economic information in order to improve the ability of stakeholders and water authorities to analyze the whole set of alternatives available, to provide transparency and to assess and adapt water decisions to the emerging water management challenges. Considering this, we present an overview of the main dri...

La agricultura es un sector clave en la economía rural y constituye un motor de crecimiento en regiones del sur de España capaces de desarrollar un regadío competitivo de alto rendimiento. Este es el caso de determinadas comarcas de la Cuenca del Guadalquivir y del Segura, que no obstante afrontan los problemas derivados de la escasez creciente de...
Article
Using a CGE model for the Balearic Islands, we simulate the effects of an agricultural water market in the farming sector facing reductions in the water endowment. The market lessens the negative effects on farming communities of short-term water restrictions associated with cyclical droughts. However, in scenarios of permanent reductions, such as...

ions to satisfy the requirements of economic activities put tremendous pressure on water ecosystems in Spain. Total abstractions represent 34.7% of available surface and groundwater resources. This rate is several times higher than in other OECD countries with greater water endowments or the potential for rainfed agricultural activities¹.

Article
Full-text available
Water is a key input in the production of many goods and services, and its scarcity might become a critical limiting factor in regional development. Water management in Spain has historically prioritized supply increases at the expense of further degradations in the resource base and has disregarded the managing of water demand and efficiency. The...
Article
The increasing economic importance of tourism activity stimulates research on the more adequate instruments to reach tourism policy targets. This paper concentrates on two tourism policy areas, namely the influence on the pattern of tourism specialization and the correction of environmental externalities, and two policy tools, that is, a tourism ta...

En el trabajo se estudia el agua como un activo económico y se definen los principios básicos para la gestión de los recursos hídricos con criterios de eficiencia. A través de tres ejemplos y de datos estilizados sobre la economía del agua en España se explica, en primer lugar, cómo la inadecuada gestión de los derechos de propiedad conduce a la so...
Article
This chapter describes the economical and financial tools to support the decision-making process, which forms part of a much broader sediment management framework, the development of societal cost-benefit analysis (SCBA), and the way it can be applied to sediment management. The chapter also presents present two examples of the application of econo...
Article
Full-text available
Abstract: The authors build a bridge between traditional analysis of the evolution of tourism destinations and economic growth theory. With this aim, they develop an environmental growth model for an economy specializing in tourism and derive the pattern of tourism development with numerical calculations. The results do not contradict the pattern o...
Article
Full-text available
A dynamic general equilibrium model of a small open economy specialized in producing tourism services is presented. The tourism package is a bundle of attri-butes provided by firms, the government and the natural environment. Investment in accommodation increases the number of visitors but also congests public goods and reduces environmental qualit...
Article
The Environmental Stewardship Scheme provides payments to farmers for the provision of environmental services based on agricultural foregone income. This creates a potential incentive compatibility problem which, combined with an information asymmetry on farm land heterogeneity, could lead to adverse selection of farmers into the scheme. However, t...
Article
Full-text available
During floods, river invertebrates may be swept downstream in large numbers. This so-called "catastrophic drift" leads to a major redistribution of animals, as well as reduced fitness and increased mortality among drifters. We present the first field evidence of the role of sediment movement in triggering catastrophic drift. Experiments indicate th...
Article
Full-text available
We use an Applied General Equilibrium Model of the Balearic Islands to explore the impact of increasing the technical e􀀡ciency of water use in the tourism sector. We show that water e􀀡ciency measures do not reduce economic pressures on water ecosystems. Consequently water price increases and reductions in water withdrawals are needed as ancillary m...

Article
Full-text available
We analyse the potential welfare gains of an agricultural water rights market. Compared to the traditional administrative allocation, the voluntary water exchanges between different agricultural sectors allow enough flexibility to cope with the cyclical draughts characteristic of the Balearic hydrological regime. To simulate the market an Applied G...
Article
Full-text available
We present a computable general equilibrium model (CGE) for the Balearic Islands, specifically performed to analyze the welfare gains associated with an improvement in the allocation of water rights through voluntary water exchanges (mainly between the agriculture and urban sectors). For the implementation of the empirical model we built the social...

The Ebro River and its tributaries (North-Eastern Spain) are regulated by over 187 dams, with a total capacity equivalent to 57% of the total mean annual runoff. We analysed 38 gauging records from 22 rivers that, by virtue of location within the drainage network and period of record, would reflect reservoir-induced hydrological changes. Most showe...
Article
In a two sectors dynamic model we analyze the process of tourism development based on the accumulation of capital (building of tourism facilities) and the reallocation of land from traditional activities to the tourism sector. The model incorporates the conflict between occupation of the territory by the tourism facilities, other productive activit...
