    Regarding the values by trimester(T)/quarter(Q) (EEA/EIONET: Q1:JFM; Q2:AMJ; Q3:JAS; Q4:OND); (APA-PT: T1:OND; T2:JFM; T3:AMJ; T4:JAS), the worst value (worst seasonal water scarcity conditions) of 2019 is reached, as would be expected, in Q3/T4 (as shown in the map – Figure 2), although the EEA/EIONET value for Q3 (58%) is lower than the value from our own calculations for T4 (67%). For this reason it is difficult to validate the data if we do not know the baseline data used.

      Thank you for your comment, however it is obvious that direct comparison between fiscal and water years could not be applied. As most of the FW-related data are reported under fiscal year range (January-December) by the national statistical institutions, we had to adjust our datasets accordingly for seasonal / annual temporal resolutions presenting the WEI+

    The value for Slovakia strongly affected by Danube River counted into renewable resources, however Danube is only “touching” Slovakia on small part of its border, water from it is not available for whole country – see the previous comment.

    • zalllnih (Nihat Zal) 14 Sep 2022 16:01:59

      Thank you for your comment. Unfortunately, the computation system we use for the WEI+ is not capable to distinct the volume of water received as inflow from upstream territory for Danube. In the case you kindly provide us the reference WEI+ for Slovakia, we would happily to replace the EEA calculation with that.

    Italy:

    At country level we cannot validate the reported estimation for worst seasonal WEI+ in 2019 since we do not have information about returns for all uses and concerning abstractions official data for 2019 are not yet available.

      Thank you for your comment, you can also validate your national data with the first version of water accounts data found here (<a href="https://www.eea.europa.eu/data-and-maps/data/wise-water-accounts-database" rel="nofollow">https://www.eea.europa.eu/data-and-maps/data/wise-water-accounts-database</a>) or with the recently updated water abstractions indicator found here (<a href="https://www.eea.europa.eu/data-and-maps/daviz/water-abstraction-by-economic-sector#tab-chart_3_filters=%7B%22rowFilters%22%3A%7B%7D%3B%22columnFilters%22%3A%7B%22pre_config_country%22%3A%5B%22Austria%22%5D%7D%7D" rel="nofollow">https://www.eea.europa.eu/data-and-maps/daviz/water-abstraction-by-economic-sector#tab-chart_3_filters=%7B%22rowFilters%22%3A%7B%7D%3B%22columnFilters%22%3A%7B%22pre_config_country%22%3A%5B%22Austria%22%5D%7D%7D</a>). Please also be kind when these data will become available to share with us for further improving the dataset and indicator assessment

    Hungary:
    In reality, in the case of Hungary, the biggest water shortage would be in Q3, and not in Q1.

    • zalllnih (Nihat Zal) 14 Sep 2022 16:05:41

       Thank you for your comment, we will re-assess the Hungarian case for balanced seasonality of the WEI+. However, in the case you have any reference data available, please be kind to share with us to improve the WEI+ computation for Hungary

    For Ireland, the national totals appear correct, however when considering the abstraction data which is being used it would appear that there has been a change since 2018. We didnt not provide abstraction data prior to 2018 and therefore the assumptions regarding NACE code may be incorrect. Primarily this relates to the use of the "electricity cooling" NACE code. Overall this should not affect the WEI+ Index.

    • zalllnih (Nihat Zal) 14 Sep 2022 16:07:13

      There was a new data collection for the latest years of 2018 and 2019, however the methothodology on the estimation of water consumption of energy production (cooling) is not change. Could you please be more specific on the effect that you mentioned on WEI+ index?

    Concerning France : our estimation fot this indicator in 2019 (worst quarter okf 2019) is probably lower (we are currently finalising estimation), as long as water consumption estimated for 2019 is lower in our data than in the displayed files.

    Furthermore, it appeared during the verification of the data at the country level  that the assumptions taken into account for the calculation of the indicator did not fully correspond to the abstraction data reported at the national level (for drinking water), and that the return coefficient for the industrial sector seemed to be very underestimated compared to our national methodology and to the data of other countries.

    With respect to our comments please note that to be able to give a more detailed  opinion and  corrections we would need to know exactly the source of the information and the definitions.

    CHECKS THAT TOOK PLACE

     The statistics coming from Eurostat in the "Reference annual data country level_2000_2019" file.

    The comments are:

    1. The data listed in Agriculture is correct except for the year 2019. A line was added and marked in red the correct quantities.
    2. The remaining amounts for Manufacturing, mining and quarrying, Services and Household, must be EEA own calculations and breakdowns, perhaps combining the total amount of Public Water Supply from Eurostat’s Table 2 and other information from other sources. We cannot confirm these data.
    • Data used to calculate the index in the file “2022-07-04_WEI plus CTY annual v10”. The only quantities, in the worksheet “1.CTY annual aggr”, which appear to be from Eurostat’s Table 1 (Renewable Freshwater Resources), are on lines 368,369,392 and 393. They have some slight differences from the quantities we sent to Eurostat. Correct values are marked in red in column G.

    Regarding the calculation of the index, in the "3.WEI calculation" worksheet, EEA calculate the Renewable Freshwater Resources variable (which is the denominator in the WEI+ index calculation formula = (abstractions - returns)/renewable freshwater resources). This quantity is very different (much smaller) than the quantity in Eurostat table 1 for the variable with the same name. But since there are no definitions, we cannot know if the coverage of the 2 variables is the same.

     

    • As a final comment, the data presented for Cyprus in the links below and in the corresponding excel files attached, have many errors which I have noted and are not consistent with the data we have sent to Eurostat.

      Thank you for your comment, all data sources along with additional explanatory text have already been mentioned in the respective sections of the indicator assessment text. Please also consult with the Supporting Information section of the indicator for respective definitions.

      Thanks also sharing your data. We will re-assess the underlying data for the WEI+ accordingly.
