Water exploitation index plus (WEI+) for river basin districts (1990-2015) This interactive map gives a European overview of water stress conditions. The information presented may deviate from that available in the EEA member countries and cooperating countries, particularly for those countries where data availability is insufficient in the WISE SoE - Water quantity database (WISE 3). Data on hydro-climatic variables were aggregated from a daily to a monthly scale. Water abstraction data were taken from WISE 3 (annual resolution at the national scale), although there are large gaps in the time series. Therefore, intensive gap filling was performed on water abstraction data and proxies were used to disaggregate the data from the national to the sub-basin scale. Information on water use was mainly modelled on the UWWTP capacities, the E-PRTR database and the Eurostat Population change dataset (online data code [demo_gind]) among others. See the methodology chapter for further explanation of gap filling, and spatial and temporal disaggregation, and the data uncertainties chapter for current data availability. This interactive map allows users to explore changes over time in water abstraction by source, water use by sector and water stress level at sub-basin or river basin scale. The WEI+ has been estimated as the quarterly average per river basin district for the years 1990-2015, as defined in the European catchments and rivers network system (ECRINS). The ECRINS delineation of river basin districts differs slightly from that defined by Member States under the Water Framework Directive. The Ecrins delineation is used instead of the WFD because it contains geospatial information on Europe’s hydrographical systems with full topological information enabling flow estimation between upstream and downstream basins, as well as integration of economic data collected at NUTS or country level. In addition to using the WISE SoE - Water quantity database, comprehensive manual data collection was performed by accessing all open sources (Eurostat, OECD, FAO), including national statistical offices of the countries. This was done because of the temporal and spatial gaps in the data on water abstraction. Moreover, a large part of the stream flow data from LISFLOOD has also been substantially updated by the Directorate-General Joint Research Centre. Similarly, a comprehensive update with climatic parameters has been performed by the EEA based on the E-OBS dataset. Therefore, the time series of the WEI+ presented in the current version might be slightly different for some basins compared with the previous version.
Water exploitation index plus (WEI+) for river basin districts (2002-2014) This interactive map allows users to explore changes over time in water abstraction by source and water use by sector at sub-basin or river basin scale. The WEI+ has been calculated as the quarterly average per river basin district, for the years 2002-2014, as defined in the European catchments and rivers network system (ECRINS). The ECRINS delineation of river basin districts differs from that defined by Member States under the Water Framework Directive, particularly for transboundary river basin districts.

Trends in annual and summer precipitation across Europe between 1960 and 2015 Grid boxes outlined in solid black contain at least three stations and so are likely to be more representative of the grid box. A black dot indicates that the long-term trend is significant at the 5% level. The classes for annual and summer precipitation differ (by factor 4) because annual precipitation covers 12 months whereas summer precipitation covers 3 months only.

Estimated soil erosion by water in Europe Calculated by the Revised Universal Soil Loss Equation (RUSLE). While the overall patterns of erosion are generally sound, the validation of erosion data can be challenging. The data presented are currently being validated through comparisons with national datasets and expert judgement. In this sense, zooming in on a specific locality can give the impression of a situation that differs from reality. In addition, the model used in this exercise does not consider localised intense precipitation.

Trends in annual precipitation across Europe between Jan 1960 and Jan 2012 The figure shows trends in annual precipitation across Europe between Jan 1960 and Jan 2012. The trends are calculated using a median of pairwise slopes algorithm (Sen, 1968 ) (Lazante, 1996). Black dots represent high confidence in the sign of the long-term trend in the box (if the 5th to 95th percentile slopes are of the same sign). Boxes which have a thick outline contain at least three stations. Area averaged annual time series of percentage changes and trend lines are shown below each map for one area in northern Europe (Blue line, 5.6o to 16.9oE and 56.2o to 66.2oN) and one in south-western Europe (red line, 350.6o to 1.9oE and 36.2o to 43.7oN).

Grid boxes outlined in solid black contain at least 3 stations and so are likely to be more representative of the grid-box. High confidence in the long-term trend is shown by a black dot.

Use of freshwater resources in Europe The WEI+ provides a measure of total water use as a percentage of the renewable freshwater resources for a given territory and time scale. The WEI+ is an advanced geo-referenced implementation of the WEI. It quantifies how much water is  abstracted monthly or seasonally and how much water is returned after use to the environment via basins. The difference between water abstraction and return is regarded as water use. 
Heating and cooling degree days This indicator looks at the following: Time series of population-weighted heating and cooling degree days averaged over Europe; Observed trends in heating and cooling degree days; Projected trends in heating and cooling degree days.
Heavy precipitation in Europe Heavy precipitation is defined as the maximum annual 5-day consecutive precipitation. Trends are calculated for the period between 1960 and 2015. Projected changes in heavy precipitation are defined as changes in the 95th percentile of daily precipitation (only days with precipitation >1 mm/day are considered). Changes between the 1971-2000 and 2071-2100 are calculated using a multi-model ensemble forced by RCP8.5.
Mean precipitation Observed trends in annual and summer precipitation across Europe 1960-2015 Projected changes in mean annual and summer precipitation (%) in the period 2071–2100 compared with the baseline period 1971–2000 for the forcing scenario RCP8.5. Model simulations are based on the multi-model ensemble average of many different RCM simulations from the EURO-CORDEX initiative.
