Suivi stationnel de l’herbier à Zostera noltei de la masse d’eau FRFT8 Bidassoa - 2015 - Bassin Hydrographique Adour-Garonne

Rossi, Nadège.

Among the biological quality elements monitored under the WFD, salt marshes are still not assessed in France. To evaluate ways to develop an assessment tool for this biological quality element, methodologies already applied by other member states have been identified and analyzed. Despite a very thorough job in assessing the ecological status of salt marshes, no pressure-impact relationship has been demonstrated. In addition, the pressures identified are related to the hydromorphological characteristics. A study was conducted to study saltmarshes not as a biological quality element but as a hydromorphological quality element. It shows that with simple procedure, it is possible to follow the evolution of the total area of salt marshes which can give...

Based on 3 metrics ("taxonomy", "extension" and "abundance"), the quality index of the water body FRFT8 – Bidassoa - Type T03 for the angiosperm indicator, was "good", the same as 2014. As last year, the seagrass bed moved and the grid will probably be displaced in 2016.

Suivi stationnel et surfacique de l'herbier à Zostera noltei de la masse d'eau FRFT08 Bidassoa 2020 - Bassin Hydrographique Adour-Garonne

Sanchez, Florence; Lissardy, Muriel; De Casamajor, Marie-noelle; Aubert, Fabien.

In 2020, the Zostera noltei seagrass bed monitoring, located on the transitional water body FRFT08 Bidassoa (Txingudi Bay, Hendaye - Pyrénées Atlantiques), was carried out from a grid of 30 sample points ("stationary" monitoring) and from a mapping within the framework of the WFD. The "angiosperms" indicator established on this water body is based on 3 metrics (composition, extent and abundance). In 2020, the calculation of this indicator classifies the water body in "Very good condition". This result is explained both by a significant increase in the seagrass bed surface area, from 1.9 ha in 2018 to 4.5 ha in 2020 and by a good abundance.

Biomarkers as tools for monitoring within the Water Framework Directive context: concept, opinions and advancement of expertise

Overview of eutrophication indicators to assess environmental status within the European Marine Strategy Framework Directive

Milinkovitch, Thomas; Geffard, Olivier; Geffard, Alain; Mouneyrac, Catherine; Chaumot, Arnaud; Xuereb, Benoit; Fisson, Cedric; Minier, Christophe; Auffret, Michel; Perceval, Olivier; Egea, Emilie; Sanchez, Wilfried.

The Water Framework Directive (WFD) currently supports chemical and ecological monitoring programmes in order to achieve the good water surface status. Although chemical and ecological assessments are necessary, they have some limitations. Chemical approaches focus on certain substances identified as priorities, but they do not take into account other potentially harmful substances and also ignore the hazards related to contaminant cocktails. On the other hand, while ecological approaches provide holistic information on the impairment of biological communities in ecosystems, they do not distinguish the role of contaminants in these alterations, and consequently do not allow the establishment of contaminant impact reduction plans. Consequently,...

In 2009, following approval of the European Marine Strategy Framework Directive (MSFD, 2008/56/EC), the European Commission (EC) created task groups to develop guidance for eleven quality descriptors that form the basis for evaluating ecosystem function. The objective was to provide European countries with practical guidelines for implementing the MSFD, and to produce a Commission Decision that encapsulated key points of the work in a legal framework. This paper presents a review of work carried out by the eutrophication task group, and reports our main findings to the scientific community. On the basis of an operational, management-oriented definition, we discuss the main methodologies that could be used for coastal and marine eutrophication assessment....

Sanchez, Florence; De Casamajor, Marie-noelle; Lissardy, Muriel.

The new protocol, established by Auby et al. (2012) to the seagrass monitoring under the Water Framework Directive, was used in Txingudi bay (Hendaye, France). Based on 3 metrics ("taxonomy", "extension" and "density"), the quality index of the water body for the angiosperm indicator, was "medium", while it was in "good condition" in 2012. These results are explained by a sharp drop in the density observed on the monitoring station. The cartography of the species distribution showed a decrease of the total area of seagrass, particularly in the southern part of the mudflat. However, further north, small intertidal seagrass spots appeared. Atypical weather conditions in 2013 (cold, heavy spring rain) with silting of this area, could explain this situation.

Détermination de Valeurs Guides Environnementales (VGE) mollusques alternatives aux Normes de Qualité Environnementale (NQE) définies dans la DCE

Sire, Alizee; Amouroux, Isabelle.

The Water Framework Directive (DCE 2000/60/CE), aims to achieve the good conditions (chemical and ecological) of different waters in Europe. The Environmental Quality Standards (EQS) are the tools used to evaluate the chemical condition waters. Initially, the EQS are defined for the water matrix, but with the analytical difficulties and low spatial and temporal representativity of water samples, the monitoring of contaminants must be carried out on alternative matrices, as mollusks and particularly the mussels. Among the 45 priority and dangerous priority substances establishes by the WFD 2013/39/UE, 25 substances are hydrophobic and bioaccumulable. The main goal of this study is to determine thresholds applicable in the mussels at least as protective as...

Modelling Agricultural Diffuse Pollution: CAP – WFD Interactions and Cost Effectiveness of Measures

Mouratiadou, Ioanna; Topp, Cairistiona; Moran, Dominic.

Within the context of the Water Framework Directive (WFD) and the Common Agricultural Policy (CAP), the design of effective and sustainable agricultural and water resources management policies presents multiple challenges. This paper presents a methodological framework that will be used to identify synergies and trade-offs between the CAP and the WFD in relation to their economic and water resources environmental effects, and to assess the cost-effectiveness of measures to control water pollution, in a representative case study catchment in Scotland. The approach is based on the combination of a biophysical simulation model (CropSyst) with a mathematical programming model (FSSIM-MP), so as to provide a better understanding and representation of the...

Fezzi, Carlo; Bateman, Ian J.; Day, Brett H.; Posen, Paulette; Rigby, Dan.

We develop a two-stage, multinomial logit model of UK land use to investigate the impact of policy changes upon agriculture. The model utilizes a large panel database covering the entirety of England and Wales for 14 years between 1969 and 2004 integrated with the economic and physical environment determinants of all major agricultural land use types. Our model performs well in out-of-sample prediction of current land use and we use it to assess a proposed implementation of the Water Framework Directive via a tax on fertilizer. Results indicate that such policy change would generate substantial switching from arable to grassland systems, reducing significantly the amount of nitrate leaching into UK water-bodies.

Gomez, Carlos Mario; Gutierrez, Carlos.

In this paper we analyze the conditions under which increasing technical efficiency of water use in the agricultural sector might not reduce water demand and pressures on water ecosystems. Departing from this basic problem we discuss how policy measures performed to enhance water productivity in the agriculture might be transformed into effective alternatives to improve the conservation of water resources and then guarantee the successful implementation of the Water Framework Directive. A preference revelation model is presented in the third section of the paper and one empirical application to an irrigation district in southern Spain is used in the fourth section to discuss the effectiveness of water savings measures.

The European Union’s Water Framework Directive (WFD) has “the purpose to protect and preserve water resources across the European Union to ensure future sustainable use” but is likely to add to agricultural land losses, e.g. to infrastructure, industrial estates and housing. While the environmental as well as the micro-economic benefits of the Directive - e.g. for water producers and consumers - are well established, there is a lack of knowledge as to its regional economic effects. Based on a system dynamics approach incorporating an input-output table, a regional model (POEMS) has been developed for the Emsland region in Northern Germany. POEMS has been employed to capture the economic, ecological and social effects of three WFD scenarios which reduce...

Saraiva, Joao Paulo; Pinheiro, Antonio Cipriano.

The major implications that the European Union (EU) Water Framework Directive (WFD) may have in irrigated agriculture were analysed using alternative water policy measures. The consequences of policy change were evaluated in a case study (Baixo Alentejo, Portugal), using a Multi-Criteria Decision Making (MCDM) model that simulates farmers’ preferred behaviour. The study compares the effects of water pricing (volumetric and flat tariffs) and consumption quotas, in farmer’s income, water agency revenues, agricultural employment and water demand for irrigation. Model results indicate that the adjustments in farmer’s responses are dependent on the policy strategy enforced and on the policy level.

The application of the Water Framework Directive where farmers have alternative water sources

Dono, Gabriele; Severini, Simone.

This paper evaluates the possible consequences of decreasing in the amount of water provided by the irrigation board to the farms, and increasing in the unitary water charges that the irrigation board applies to the farms. The study has been conducted in a Mediterranean region of southern Italy where farmers can use water delivered by an irrigation board and by privately owned wells. The results of the analysis, performed by means of a mathematical programming model, show that in both cases farmers substitute the water supplied by the irrigation board with that extracted from farm wells. This generates an over-extraction of resources from the aquifer leading to likely negative environmental consequences. This also endangers the economic sustainability of...

Jacobsen, Brian H.; Abildtrup, Jens; Orum, Jens Erik.

An analysis for the implementation of the Nitrate Directive in the EU indicates that probably only three of 15 countries have implemented the directive satisfactorily. These countries are Sweden, Finland, Denmark and Austria, however other countries are in the process of getting their implementation accepted. As an example, the Netherlands has been forced to abandon the MINAS system in order to get its implementation accepted by the EU. The continues by describing the costs related to implementation of the Aquatic Plan II in Denmark. The costs have been calculated to 70 million or 2,0 per kg N in reduced leaching. The farmers have paid 60% of the costs. The paper then describes the measures taken in Denmark and the associated costs for the state and...
