REPORT ON SPANISH RIVER BASIN PLANS OF THE THIRD CYCLE: CLIMATE CHANGE AND KEY ASPECTS IN THE IMPLEMENTATION OF THE WATER FRAMEWORK DIRECTIVE 2 0 2 4

The report argues that Spanish river basin planning continues to prioritise socioeconomic demands over environmental objectives, leading to the degradation of aquatic ecosystems. It identifies systemic failures in quantifying water resources under climate change, an over-reliance on ineffective irrigation modernisation, and the misuse of WFD exemptions to defer environmental recovery. Case studies of the Tagus, Ebro Delta, Doñana, and Mar Menor illustrate severe overexploitation and pollution, while the Alcolea dam project is cited as an example of flawed cost-recovery and strategic planning.

• Spanish river basin management plans (RBMPs) for the third cycle (2022-2027) show an unjustified increase in estimated natural water resources, which contradicts climate change predictions. For example, the Ebro RBMP shows an increase of 578 hm3 per year, and the Guadalquivir's resources increased from 5754 hm3/year in 2013 to 7092 hm3/year in 2015.
• The Water Exploitation Index (WEI+) reveals widespread water stress across Spanish basins. In the Segura basin, the WEI+ is 77%, but would reach 185% if desalination and Tagus-Segura transfers are excluded. In the Tagus basin, 77% of water bodies are above the 20% stress indicator.
• Irrigation modernisation is the primary adaptation measure proposed in RBMPs, but it is described as counterproductive. Evidence suggests it promotes higher water consumption through crop intensification and double cropping, and the European Court of Auditors reported in 2021 that it likely increases water use.
• Special Drought Plans (PES) are criticised for being reactive and focused on maintaining socioeconomic uses rather than protecting ecosystems. The report notes an abuse of the 'exceptional drought' concept to justify the deterioration of water bodies, with 'prolonged droughts' occurring every 3 to 4 years in the Ebro (26-31% of the period).
• There is an excessive use of WFD exemptions (Articles 4.4, 4.5, and 4.7) to defer the achievement of 'good status' for water bodies. Many extensions to 2027 are based on 'natural causes' despite a lack of evidence that necessary measures were applied or were effective.
• The implementation of environmental flow regimes is deemed a failure. While minimum flows (Qmin) are now defined for most bodies, other mandatory components like flood flows (Qg) and exchange rates (Tc) are largely absent, particularly in the Guadalquivir basin where neither has been established.
• The River Tagus suffers from severe overexploitation due to the Tagus-Segura water transfer, which diverts 45.6% to 60% of headwater reservoir water. Environmental flows for the Tagus axis are being implemented progressively and will not reach the minimum regime until January 2027.
• The Ebro Delta is experiencing regression due to the regulation of the lower Ebro by reservoirs, which prevents sediment transport. The RBMP uses an arbitrary minimum environmental flow of 100 m3/s set in 1999, which the report claims is biased toward hydroelectric interests.
• Doñana's wetlands are degrading due to illegal groundwater extractions for industrial strawberry and red fruit farming. The Guadalquivir RBMP fails to account for these illegal uses in its planning and proposes controversial external water transfers, including a new dam at Alcolea.
• The Mar Menor lagoon has suffered a catastrophic eutrophic crisis and massive mortality of aquatic organisms due to nutrient pollution from agricultural fertilisers. The Segura RBMP is criticised for not recognising the main reasons for diffuse pollution or including measures to reduce agricultural demand.
• The Alcolea dam project on the Odiel River is flagged for poor water quality due to acid and heavy metal contamination from mining. The report argues the project misuses the 'overriding public interest' exemption and has an inadequate cost-recovery estimate.
