(a)
Arguments of the parties
27
The Commission submits that, in breach of Article 4(1)(b)(i) of Directive 2000/60, the Kingdom of Spain has failed to take the measures necessary to prevent the deterioration of the status of the bodies of groundwater in the Doñana protected natural area. The Commission states that that provision, read in conjunction with point 2.1.2 of Annex V to that directive, requires Member States to ensure that anthropogenic interventions do not alter the level of groundwater, thereby causing damage to terrestrial ecosystems which depend directly on those bodies of water.
28
The Commission emphasises, in particular, that the Guadalquivir Basin Hydrological Plan 2009 to 2015 and the Guadalquivir Basin Hydrological Plan 2015 to 2021 demonstrate that the Kingdom of Spain has failed to fulfil its obligations under Article 4(1)(b) of Directive 2000/60.
29
Thus, first, the Commission claims that, by incorrectly stating in the Guadalquivir Basin Hydrological Plan 2009 to 2015 that the Almonte-Marismas aquifer was of ‘good quantitative status’ for the purposes of point 2.1.2 of Annex V to Directive 2000/60, the Kingdom of Spain underestimated the continuing deterioration caused by overexploitation of the aquifers in the Doñana region through the steady increase in excessive abstraction of water for irrigable land and failed to adopt the measures necessary to prevent that deterioration. The Commission points out, in that regard, that the decrease in groundwater levels in that aquifer has led to the acidification of temporary lagoons, thereby causing significant damage to terrestrial ecosystems which depended directly on that aquifer.
30
Secondly, the Commission argues that the alleged deterioration was confirmed by the approval of the Guadalquivir Basin Hydrological Plan 2015 to 2021, in which the Almonte-Marismas aquifer was divided into five groundwater bodies. The Commission notes that in that hydrological plan it was officially recognised that three of those water bodies, namely Marismas, Almonte and La Rocina (‘the three water bodies’), were of poor quantitative status and that two of them, namely Marismas and Almonte, were also of poor chemical status.
31
Finally, the Commission highlights that the deterioration of the three water bodies, which feed the Almonte-Marismas aquifer, is still ongoing, as is attested by a report of the Confederación Hidrográfica del Guadalquivir (Guadalquivir Hydrographic Confederation, Spain), and continues to cause damage to terrestrial ecosystems which depend directly on those bodies of water, even after the adoption of the measures included in the Guadalquivir Basin Hydrological Plan 2015 to 2021.
32
The Kingdom of Spain disputes the Commission’s arguments and maintains that the obligations arising from Article 4(1)(b) of Directive 2000/60 have been complied with fully, first of all, by the Guadalquivir Basin Hydrological Plan 2009 to 2015 and, subsequently, by the Guadalquivir Basin Hydrological Plan 2015 to 2021.
33
On the one hand, the Kingdom of Spain asserts that Article 4(4) of Directive 2000/60 provides for the possibility of postponing compliance with the obligations arising from Article 4(1)(b) thereof for the purposes of the phased achievement of the ‘objectives for bodies of water’. The Kingdom of Spain maintains that it availed itself of that possibility, having determined, after the entry into force of the Guadalquivir Basin Hydrological Plan 2015 to 2021, that it was not possible to achieve the objective of good quantitative status of the Almonte-Marismas aquifer, in particular so far as concerns the three water bodies.
34
On the other hand, the Kingdom of Spain claims that appropriate measures have been established in order to comply with the provisions of Directive 2000/60 and thus to avoid further deterioration of the water bodies concerned. Those measures include a reduction of approximately 10% of total water abstraction from the water bodies, the classification of the three water bodies not achieving the objective of ‘good quantitative status’ as water bodies ‘at risk of not achieving good quantitative status’, the replacement of groundwater abstraction with surface water abstraction, more frequent inspections in the Doñana region since 2015 in order to prevent unauthorised water abstraction, the initiation of penalty proceedings and the closure of wells from which water is illegally abstracted. The Kingdom of Spain states that the measures adopted have been effective in so far as, first, the continuing deterioration of the Almonte water body has been halted and, secondly, the status of the La Rocina and Marismas water bodies has been enhanced.
(b)
Assessment of the Court
35
As a preliminary remark, it must be pointed out that Directive 2000/60 is a framework directive adopted on the basis of Article 175(1) EC (now Article 192(1) TFEU). It establishes common principles and an overall framework for action in relation to water protection and coordinates, integrates and, in a longer perspective, develops the overall principles and the structures for protection and sustainable use of water in the European Union. The common principles and overall framework for action which it lays down are to be developed subsequently by the Member States by means of the adoption of individual measures in accordance with the timescales laid down in the directive. However, the directive does not seek to achieve complete harmonisation of the rules of the Member States concerning water (judgment of
1 July 2015,
Bund für Umwelt und Naturschutz Deutschland
, C‑461/13, EU:C:2015:433, paragraph 34
and the case-law cited).
36
According to Article 1(a) of Directive 2000/60, the purpose of the directive is to establish a framework for the protection of inland surface waters, transitional waters, coastal waters and groundwater which prevents further deterioration and protects and enhances the status of aquatic ecosystems and terrestrial ecosystems directly depending on the aquatic ecosystems (judgment of
1 July 2015,
Bund für Umwelt und Naturschutz Deutschland
, C‑461/13, EU:C:2015:433, paragraph 36
).
37
Therefore, the ultimate objective of Directive 2000/60 is to achieve, through coordinated action, ‘good status’ of all EU waters, including groundwater.
38
The environmental objectives which Member States are required to achieve for groundwater are specified in Article 4(1)(b) of Directive 2000/60.
39
That provision imposes two separate, albeit intrinsically linked, obligations. First, pursuant to Article 4(1)(b)(i) of Directive 2000/60, Member States are to implement the measures necessary to prevent or limit the input of pollutants into groundwater and to prevent the deterioration of the status of all bodies of groundwater. Secondly, pursuant to Article 4(1)(b)(ii) and (iii) thereof, Member States are to protect, enhance and restore all bodies of groundwater with the aim of achieving good status at the latest by the end of 2015. It follows that the first obligation arising from Article 4(1)(b)(i) of Directive 2000/60 is an obligation to prevent the deterioration of the status of all bodies of groundwater, whereas the second obligation, set out in Article 4(1)(b)(ii) and (iii) of that directive, is an obligation to enhance that status (see, to that effect, judgment of
28 May 2020,
Land Nordrhein-Westfalen
, C‑535/18, EU:C:2020:391, paragraph 69
).
40
Furthermore, Article 4(1) of Directive 2000/60 establishes a link between the measures of conservation necessary to prevent the deterioration of the status of all bodies of groundwater which the Member States are bound to adopt under that provision and the prior existence of a management plan for the river basin district concerned (see, to that effect, judgment of
11 September 2012,
Nomarchiaki Aftodioikisi Aitoloakarnanias and Others
, C‑43/10, EU:C:2012:560, paragraph 52
).
41
Furthermore, it should be recalled that, in order to ensure that Member States attain the qualitative objectives pursued by the EU legislature, namely the preservation or restoration of good quantitative and chemical status of groundwater, Directive 2000/60 lays down a series of provisions, including Articles 5 and 11 and Annex V, establishing a complex process involving a number of extensively regulated stages, for the purpose of enabling the Member States to implement the necessary measures, on the basis of the specific features and the characteristics of the bodies of water identified in their territories (see, to that effect, judgment of
1 July 2015,
Bund für Umwelt und Naturschutz Deutschland
, C‑461/13, EU:C:2015:433, paragraphs 41 and 42
).
42
Finally, it follows from the wording, the scheme and the purpose of Article 4 of Directive 2000/60 that the obligations laid down in Article 4(1)(a) and (b) of that directive for surface water and groundwater are binding (see, to that effect, judgment of
28 May 2020,
Land Nordrhein-Westfalen
, C‑535/18, EU:C:2020:391, paragraph 72
).
43
It follows, as the Commission submits, that Article 4(1)(b) of Directive 2000/60 does not simply set out, in programmatic terms, mere management-planning objectives, but has binding effects, once the ecological status of the body of water concerned has been determined, at each stage of the procedure prescribed by that directive (judgment of
28 May 2020,
Land Nordrhein-Westfalen
, C‑535/18, EU:C:2020:391, paragraph 73
).
44
In the context of the present complaint, the Commission criticises the Kingdom of Spain only for failing to fulfil its obligation to prevent the deterioration of the status of bodies of groundwater under Article 4(1)(b)(i) of Directive 2000/60.
45
It follows that it is necessary, at the outset, to reject the Kingdom of Spain’s argument that Article 4(4) of Directive 2000/60 allowed it to postpone compliance with the obligations arising from Article 4(1)(b) of that directive as regards, in particular, the three water bodies located within the Doñana protected natural area. As the Advocate General noted in point 153 of her Opinion, the exception of postponing achievement of the objectives laid down in Article 4(1)(b) of Directive 2000/60 is applicable only to the enhancement obligation laid down in Article 4(1)(b)(ii), but not to the obligation to prevent deterioration referred to in Article 4(1)(b)(i), which the Commission claims has not been fulfilled in the present case.
46
As regards the question whether the Kingdom of Spain has failed to fulfil its obligation to prevent the deterioration of the status of the bodies of groundwater in the Doñana protected natural area, in infringement of Article 4(1)(b)(i) of Directive 2000/60, it should be recalled, first of all, that, according to settled case-law, in proceedings for failure to fulfil obligations, it is for the Commission to prove the existence of the alleged infringement and to provide the Court with the information necessary for it to determine whether there has indeed been an infringement, and the Commission may not rely on any presumption for that purpose (see, to that effect, judgment of
5 March 2020,
Commission v Cyprus (Collection and treatment of urban waste water)
, C‑248/19, not published, EU:C:2020:171, paragraph 20
and the case-law cited).
47
Next, it is only where the Commission has adduced sufficient evidence to establish the existence of the alleged infringement that it is incumbent on the Member State to challenge in substance and in detail the information produced and the inferences drawn (see, by analogy, judgment of
28 March 2019,
Commission v Ireland (System for collecting and treating waste water)
, C‑427/17, not published, EU:C:2019:269, paragraph 39
and the case-law cited).
48
Finally, according to the case-law, it is clear from the scheme of Article 4 of Directive 2000/60 that a deterioration of the status of a body of water, even if transitory, is authorised only subject to strict conditions and that the threshold beyond which breach of the obligation to prevent deterioration of the status of a body of water is found must be low (see, to that effect, judgment of
1 July 2015,
Bund für Umwelt und Naturschutz Deutschland
, C‑461/13, EU:C:2015:433, paragraph 67
).
49
As the Advocate General pointed out in points 123 to 134 of her Opinion, the concept of ‘deterioration’, within the meaning of that provision, in the context of groundwater which is already of poor status, presupposes a further increase of the already existing deficit and thus increased overexploitation as compared with an earlier situation. In that regard, the absence of a balance between abstraction and recharge of groundwater means that a body of groundwater is not of good quantitative status, as defined in point 2.1.2 of Annex V to Directive 2000/60, without thereby constituting in itself a deterioration, within the meaning of Article 4(1)(b)(i) of that directive. The adoption of the measures necessary to achieve that balance, such as an end to excessive abstraction, and consequently good status of the groundwater body in question, is covered by the enhancement obligation under Article 4(1)(b)(ii) of that directive. Accordingly, as long as the level of overexploitation of a body of groundwater of poor quantitative status does not increase, there cannot be any deterioration of that status which is contrary to the obligation under Article 4(1)(b)(i) of that directive.
50
The Commission considers that there is a deterioration of the status of the bodies of groundwater in the Doñana protected natural area, for the purposes of Article 4(1)(b)(i) of Directive 2000/60, on the grounds, first, that the Guadalquivir Basin Hydrological Plan 2009 to 2015 incorrectly classifies the quantitative status of the Almonte-Marismas aquifer, secondly, that the Guadalquivir Basin Hydrological Plan 2015 to 2021 classifies the three water bodies as of ‘poor quantitative status’ and, thirdly, that, as a result of the insufficient measures adopted in the Guadalquivir Basin Hydrological Plan 2015 to 2021, the status of the three water bodies has deteriorated.
(1) The incorrect classification, in the Guadalquivir Basin Hydrological Plan 2009 to 2015, of the quantitative status of the Almonte-Marismas aquifer
51
The Commission criticises the Kingdom of Spain, in the first place, for having incorrectly stated, in the Guadalquivir Basin Hydrological Plan 2009 to 2015, that the Almonte-Marismas aquifer had ‘good quantitative status’, for the purposes of point 2.1.2 of Annex V to Directive 2000/60, and for considering, therefore, that the groundwater level of that aquifer was not subject to anthropogenic alterations likely to result in a failure to achieve the environmental objectives laid down by that directive or was not likely to cause environmental damage to ecosystems which depend directly on it. In the Commission’s view, that incorrect classification is evidence that the Kingdom of Spain has not taken the measures necessary to prevent the deterioration of the status of the bodies of groundwater in the Doñana region, in particular in order to reduce excessive water abstraction.
52
As is apparent from the documents before the Court, on the date of approval of the Guadalquivir Basin Hydrological Plan 2009 to 2015, that is to say on 17 May 2013, there was sufficient evidence to conclude that the Almonte-Marismas aquifer did not fulfil the requirements laid down for classification as a body of water of ‘good quantitative status’, for the purposes of point 2.1.2 of Annex V to Directive 2000/60.
53
The Commission has provided several documents from various scientific and official sources, which it has annexed to its application, showing that, at the time of approval of that plan, the Almonte-Marismas aquifer was at risk of not achieving the objectives laid down by Directive 2000/60 because of anthropogenic alterations and, in particular, excessive water abstraction from irrigable land in the Doñana region.
54
Moreover, as the Commission argues, the Land Use Plan for the Doñana Region, approved by Decreto 341/2003 del Gobierno de la Comunidad Autónoma de Andalucía por el que se aprueba el Plan de Ordenación del Territorio del ámbito de Doñana y se crea su Comisión de Seguimiento (Royal Decree 341/2003 of the Government of the Autonomous Community of Andalusia approving the Land Use Plan for the Doñana Region and establishing its Monitoring Committee) of 9 December 2003 (BOJA No 22, of 3 January 2004, p. 2866), had already recommended to the Spanish Water Administration that it declare the Almonte-Marismas aquifer to be, in its entirety, overexploited or at risk of being overexploited, with a view to reducing the risk of overexploitation and deterioration of the quality of the waters in that aquifer.
55
However, although the evidence referred to in paragraphs 53 and 54 of the present judgment, which dates from 2003, 2008, 2009 and 2012, is capable of showing that the Almonte-Marismas aquifer was not of ‘good quantitative status’, for the purposes of point 2.1.2 of Annex V to Directive 2000/60, at the date of approval of the Guadalquivir Basin Hydrological Plan 2009 to 2015, such evidence cannot, however, support a finding that the incorrect classification of the quantitative status of that aquifer in the plan led to the groundwater bodies in the Doñana protected natural area undergoing a deterioration, as defined in paragraph 48 of the present judgment.
56
It follows from the foregoing that the Commission has not demonstrated that the Kingdom of Spain has failed to fulfil its obligations under Article 4(1)(b)(i) of Directive 2000/60, by incorrectly classifying the quantitative status of the groundwater bodies in the Doñana protected natural area in the Guadalquivir Basin Hydrological Plan 2009 to 2015.
(2) The classification of the three water bodies as of ‘poor quantitative status’ in the Guadalquivir Basin Hydrological Plan 2015 to 2021
57
The Commission submits that the evidence of the deterioration of the quantitative status of the Almonte-Marismas aquifer follows from the fact that, when the Guadalquivir Basin Hydrological Plan 2015 to 2021 was approved in January 2016, that aquifer was divided into five water bodies, with the three water bodies being considered to be of ‘poor quantitative status’, for the purposes of point 2.1.2 of Annex V to Directive 2000/60. In the Commission’s view, the amendment of that plan constitutes an implicit indication that the status of the groundwater bodies in the Doñana protected natural area has deteriorated as compared with their status as set out in the Guadalquivir Basin Hydrological Plan 2009 to 2015.
58
However, such a line of argument cannot be accepted.
59
It is apparent from the file submitted to the Court that the new classification of the quantitative status of the groundwater bodies in the Doñana protected natural area is merely the consequence of dividing the Almonte-Marismas aquifer as a whole into five separate water bodies for the purposes of its assessment. As a result of that division, the poor quantitative status of the three water bodies became apparent, whereas in the Guadalquivir Basin Hydrological Plan 2009 to 2015, the Almonte-Marismas aquifer, which was assessed as a whole, was considered to be of good quantitative status.
60
Thus, as the Kingdom of Spain has established, following approval of the Guadalquivir Basin Hydrological Plan 2009 to 2015, the information which has been gradually collected has shown that that plan was lacking technical precision as regards the initial measures implementing Directive 2000/60. For that reason, the Almonte-Marismas aquifer was divided into five separate water bodies in the Guadalquivir Basin Hydrological Plan 2015 to 2021, with a view to locating problems more easily at a territorial level, identifying more precisely the areas at risk of not achieving the objectives laid down by that directive and thus developing a more effective and appropriate response, consisting essentially in reducing groundwater abstraction.
61
Moreover, the evidence produced by the Commission is not capable of showing that the three water bodies considered to be of ‘poor quantitative status’ were in better status before the Almonte-Marismas aquifer was divided up. On the contrary, as is apparent from paragraph 52 of the present judgment, the documents provided by the Commission prove that, prior to the approval of the Guadalquivir Basin Hydrological Plan 2009 to 2015, there was sufficient evidence to consider that that aquifer was not of good quantitative status. Accordingly, it cannot be inferred from the reference, in the Guadalquivir Basin Hydrological Plan 2015 to 2021, to the poor quantitative status of the three water bodies that there had been a further deterioration in that status as compared with the status reported in the Guadalquivir Basin Hydrological Plan 2009 to 2015.
62
It follows that the Commission has not shown that the amendment of the ‘good quantitative status’ classification of the Almonte-Marismas aquifer, as contained in the Guadalquivir Basin Hydrological Plan 2009 to 2015, in the form of the reference to the three water bodies being of ‘poor quantitative status’ in the Guadalquivir Basin Hydrological Plan 2015 to 2021, was the consequence of a deterioration of the status of that aquifer, as defined in paragraph 48 of the present judgment.
(3) The deterioration of the water bodies in the Doñana protected natural area as a result of the allegedly insufficient measures adopted in the Guadalquivir Basin Hydrological Plan 2015 to 2021
63
The Commission maintains that, as a result of the insufficient measures adopted by the Guadalquivir Basin Hydrological Plan 2015 to 2021, a ‘deterioration’, within the meaning of Article 4(1)(b)(i) of Directive 2000/60, is ongoing and has not yet been reversed, with the risk that the good quantitative status of the three water bodies will not be achieved within the time limits set out in that directive.
64
As a preliminary point, it should be recalled that, according to settled case-law, as the question whether a Member State has failed to fulfil obligations must be determined by reference to the situation prevailing in the Member State at the end of the period laid down in the reasoned opinion, the Court cannot take account of any subsequent changes (see judgment of
28 March 2019,
Commission v Ireland (System for collecting and treating waste water)
, C‑427/17, not published, EU:C:2019:269, paragraph 140
and the case-law cited).
65
In the present case, since the deadline laid down in the reasoned opinion is 29 June 2016, it is necessary to disregard some of the evidence produced by the Commission to demonstrate the continuing deterioration of the quantitative status of the bodies of groundwater in the Doñana protected natural area, in particular, most of the Spanish press articles and the reports of the non-governmental organisation the World Wildlife Fund (WWF) which contain information relating to 2017, 2018 and 2019.
66
As regards the question whether the Kingdom of Spain failed to fulfil its obligation to prevent the deterioration of those bodies of water up until 29 June 2016, the Commission takes the view, in essence, that the present and continuing deterioration of the quantitative status of those bodies of water is demonstrated, first, by the excessive and ongoing abstraction of groundwater in the Doñana region and, secondly, by the deterioration of surface waters and ecosystems.
67
With regard to the excessive and ongoing abstraction of groundwater in the Doñana region, the Commission claims that various items of evidence from scientific studies, reports of the Spanish authorities and press articles, copies of which are annexed to the application, bear out the slow and steady increase in the irrigated area of the Doñana region since 2000.
68
While it is true that such evidence may be indicative of continuing overexploitation of the Almonte-Marismas aquifer, the fact remains that those documents do not show that such overexploitation has increased further, causing a deterioration of that aquifer since the approval of the Guadalquivir Basin Hydrological Plan 2015 to 2021 on 8 January 2016.
69
The documents produced by the Commission, in particular the report of the Guadalquivir Hydrographic Confederation of April 2017 on the status of the Almonte-Marismas aquifer for the 2015 to 2016 hydrological year and the report of the Defensor del Pueblo (Ombudsman, Spain) of 10 August 2018, both annexed to the application, merely warn that the continuing use of groundwater resources threatens the good status of that aquifer and the terrestrial ecosystems which depend directly on it, with the risk that the three water bodies considered to be of poor quantitative status may not achieve good quantitative status. However, as pointed out in paragraph 49 of the present judgment, the fact that the bodies of groundwater remain of poor quantitative status does not in itself mean that the quantitative status of those bodies of groundwater has further deteriorated since the approval of the Guadalquivir Basin Hydrological Plan 2015 to 2021.
70
Moreover, as the Advocate General pointed out in point 130 of her Opinion, in the event of poor quantitative groundwater status, the obligation to prevent the deterioration of that status, referred to in Article 4(1)(b)(i) of Directive 2000/60, cannot require the reduction of excessive groundwater abstraction to the point of achieving a balance between groundwater abstraction and renewal. Such a balance meets the definition of good quantitative status for the purposes of the first sentence of point 2.1.2 of Annex V to that directive, which must be achieved in the context of the enhancement obligation under Article 4(1)(b)(ii) and (iii) of that directive, fulfilment of which has not been challenged in the context of the present complaint.
71
Accordingly, it follows from the foregoing considerations that, in the event that bodies of groundwater are of poor quantitative status, as found in the Guadalquivir Basin Hydrological Plan 2015 to 2021, the obligation to prevent the deterioration of the quantitative status of those bodies of water, referred to in Article 4(1)(b)(i) of Directive 2000/60, requires only that groundwater abstraction should not increase further, so as not to exacerbate the causes of the poor quantitative status established. However, the Commission has provided no evidence that groundwater abstraction increased following the approval of the Guadalquivir Basin Hydrological Plan 2015 to 2021 or that the causes of the poor quantitative status of the Almonte-Marismas aquifer were exacerbated.
72
By contrast, the Kingdom of Spain has provided monitoring data collected by the Guadalquivir Hydrographic Confederation showing that, at least since 2015, the indicator of the status of the groundwater bodies of the Almonte-Marismas aquifer shows a trend towards returning to its previous levels, which is observable for the groundwater bodies of the Almonte-Marismas aquifer as a whole as well as for the three water bodies, in particular that of La Rocina. Thus, according to the available official records, since approximately 2015 there has been a very small improvement in the groundwater bodies of the Doñana protected natural area as a result of the implementation of specific measures to reduce groundwater abstraction in the Doñana region.
73
In the light of the foregoing considerations, it must be held that the Commission has not shown that the poor quantitative status of the bodies of groundwater in the Doñana protected natural area has been worsened by increased abstraction, in breach of the obligation to prevent the deterioration of groundwater laid down in Article 4(1)(b)(i) of Directive 2000/60.
74
With regard to the deterioration of surface waters and ecosystems, it should be noted, as did the Advocate General in point 149 of her Opinion, that such deterioration may constitute evidence that the groundwater bodies concerned are of poor quantitative status but cannot constitute evidence of further deterioration of that status. Nor has the Commission established that such evidence shows a worsening of the poor quantitative status of the groundwater bodies in the Doñana protected natural area in their entirety.
75
It follows that the Commission has not demonstrated the existence of a deterioration of the three water bodies as a result of the measures which were established in the Guadalquivir Basin Hydrological Plan 2015 to 2021.
76
It follows from all the foregoing that the Commission has not shown that the Kingdom of Spain has failed to fulfil its obligation to prevent the deterioration of the status of the bodies of groundwater in the Doñana protected natural area, for the purposes of Article 4(1)(b)(i) of Directive 2000/60.
