2. PWFA complemented by asset accounts for water resources.
Mapping the JQ - IW with water accounts > Introduction
OECD/Eurostat Joint Questionnaire Inland Waters (JQ-IW) : national water statistics (water resources, water use and wastewater treatment).
Physical water flow accounts (PWFA) : water flows and emissions to water in relation to the economic activities.
PWFA complemented by asset accounts for water resources.
Water accounts
to align water information closer to national accounts
integration of water related concerns into macro-economic monitoring, analyses, modelling, and theory building.

3. Water statistics Water accounting.
Mapping the JQ - IW with water accounts > Introduction
Water statistics Water accounting.
Water statistics and water accounting share many definitions
Water accounts tables widely based and dependent on JQ-IW data
Eurostat developed DSD which may host the JQ-IW and the PWFA items
To what extent can we fill in water accounting tables using JQ-IW data?
How much cells in the JQ-IW coincide with cells in PWFA-questionnaire and vice versa ?
Which has been so far the response rate for the JQ-IW items to be used to fill in water accounts table?

Mapping the JQ - IW with water accounts > Summing up
Asset accounts:
no opening/closing stock of water resources;
no soil water;
discoveries of water in aquifers are not available
most of the items from Table 1;
returns can be obtained from Table 8 (discharges of urban wastewater, industrial wastewater and agricultural wastewater) and Table 2 (water returned without use);
abstraction is available from Table 3;
the response rate is above 50% for most of the items (available from the JQ-IW).

12. Mapping the JQ - IW with water accounts > Summing up
PWFA – Water PSUT:
no soil water, no detail for water related products (steam and hot water), no water incorporated in products.
Supply table:
Flows within the economy: only water from the public water system and wastewater fluxes.
Flows from the economy to the environment: no disaggregated information by NACE for the supply table.
Use table:
Detailed overview of the water abstracted by sector, of the water supplied by the public water system to the other sectors of the economy and of the total discharges (including losses) to the environment.
Good coverage of flows from the environment to economy and within economy.
Unsufficient (detailed) coverage of flows from the economy to the environment.

13. PWFA – Emissions to water PSUT:
Mapping the JQ - IW with water accounts > Summing up
PWFA – Emissions to water PSUT:
all the information required from table 8;
the information on the destination of water emissions (to water or to NACE 37) is not directly available;
use table: this information can only partially be derived from the JQ-IW..
Data availability is quite low.
