Section B – Statistical units of the environment
Section C – Definition of institutional units
Section D – Classification of establishments
Section E – Characteristics of statistical units
Question 1 – Is the definition of statistical
units appropriate for the purposes of
IRWS?
•
•
•
The definition of statistical units used in the
IRWS is “a statistical unit is an entity about
which information is sought and for which
statistics are ultimately compiled”.
In economic statistics this relates almost
exclusively to institutional units
Some do not agree that statistical units cover the
environment and the reason for having this units
is not clear to others
Section B – Statistical units of the
environment
• Surface water (EA 131)
• Artificial reservoirs (EA 1311)
• Lakes (EA 1312)
• Rivers (EA 1313)
• Snow, ice and glaciers (EA 1314)
• Groundwater (EA 132)
• Soil water (EA 133)
Question 2 – Do you agree with the
definition of physical units of the
environment?
•
•
•
The physical units of the environment are the
statistical units about which we want to collect
information, i.e. lakes, rivers, artificial reservoirs, etc.
(it is suggested to add wetlands)
The information about those physical units in the
environment has to be collected or compiled from
institutional units who are responsible for their
management.
It is important that the register of the physical units is
linked to the register of the institutional units that
manage or collect data about the particular water
resource.
Questions 3 – Should the large artificial
reservoirs be separated from the small
ones? (e.g. large dams from farm dams).
A definition is available from International Commission on
Large Dams:
• Large dams are defined as dams with a crest or wall
height of greater than 15 metres, or as dams with a dam
wall height of greater than 10 metres but meeting other
size criteria as follows: having a crest more than 500
metres in length; creating a reservoir capacity of no less
than 1,000 ML; the ability to deal with a flood discharge
of no less than 2,000 cubic metres per second; or, being
of unusual design
Section C – Definition of institutional
units
•
•
•
•
•
The main attributes of an institutional unit are:
(a) It is entitled to own goods or assets in its own right; it is
therefore able to exchange the ownership of goods or assets in
transactions with other institutional units;
(b) It is able to take economic decisions and engage in economic
activities for which it is itself held to be directly responsible and
accountable at law;
(c) It is able to incur liabilities on its own behalf, to take on other
obligations or future commitments and to enter into contracts;
and
(d) Either it has a complete set of accounts, including a balance
sheet of assets and liabilities, or it would be possible and
meaningful, from both an economic and legal viewpoint, to
compile for it a complete set of accounts, if required
Question 4 – Do you agree with using the
term “institutional unit” in the IRWS?
•
The IRWS follows the 2008 SNA and uses
the terminology “institutional units” as
opposed to “economic units” which was
used in the SEEAW, which followed the
1993 SNA.
Section D – Classification of
establishments
An industry is a group of the establishments
within the economy that are engaged in the
same, or similar, kinds of production activity
The productive activity of institutional units
is termed principal, secondary or ancillary
activity:
Section D – Classification of
establishments … cont.
The principal activity is the activity whose value added
exceeds that of any other activity carried out within the
same unit and whose output must be suitable for delivery
outside the institutional unit.
A secondary activity is an activity carried out within a single
institutional unit in addition to the principal activity and
whose output must be suitable for delivery outside the
institutional unit.
An ancillary activity is incidental to the main activity of the
institutional unit. It does not normally result in goods and
services that can be marketed

Questions 5 – Is it necessary to present the
classification of establishments by
institutional sectors?
•
•
•
•
The classification of establishments by institutional sectors is
required for the compilation of national accounts.
SEEAW includes reference to the institutional sector but does
not use the institutional sectors in the presentation of the
accounts.
For theoretical completeness in the discussion of institution
units and because it could be beneficial, and would be possible
for many countries to present water statistics according to
institutional sectors it is currently included in IRWS.
At present it seems that no country compiles water accounts or
water statistics by institutional sector.
Question 6 – Are the most important
industries relevant to water statistics
identified?
Currently included:
• Agriculture (ISIC Rev. 4, Div. 01)
• Mining (ISIC Rev. 4, Div. 05-09)
• Manufacturing (ISIC Rev. 4, Div. 10-33)
• Electricity supply (ISIC Rev. 4, Div. 35)
• Water supply (ISIC Rev. 4, Div. 36)
• Sewerage (ISIC Rev. 4, Div. 37)
• Others industries mentioned: Forestry and fishing;
Water transport; Accommodation; Food and beverage
services; Sports activities and amusement and
recreation activities
Question 7 – Should the electricity
industry be explicitly divided into hydroelectric producers and other types of
producers?
• It has been proposed that because hydropower generators use, but do not consume
water, they are different from other types of
electricity producers, and hence should be
separately identified.
Section E – Characteristics of statistical
units
Characteristics of inland water resources
• 1. Name
• 2. Identification code
• 3. Location
• 4. Type of water resource
• 5. Organisation responsible for management
6. Physical characteristics
Section E – Characteristics of statistical
units … cont.
Characteristics of institutional units
• 1. Identification code
• 2. Location
• 3. Industry
• 4. Type of economic organisation
• 5. Type of legal organisation
• 6. Size
Question 8 – Is the order of the
characteristics of inland water resources
appropriate?
•
•
As it is important to link the physical units
with the institutional units, to make this
point clearer, should the order of
presentation of the characteristics of
inland water resources change to show as
first characteristic the organization
responsible for management?
Note that at present the order is consistent
with the order of the characteristics of
institutional units
Question 9 – Should Characteristic 5 be
changed to explicitly allow for multiple
organisations management to be
identified?
•
It is recognised that that in water many
agencies can be responsible for the
management of different water resources
•
Apart from allowing for the recording of
multiple agencies of management, how
else could this be reflected in the
characteristics of the inland water
resources?
Question 10 – Are any important
characteristics of inland water resources
and institutional units missing?
•
•
Statistical units may be characterised by a
number of descriptive data items that help
uniquely identify them and facilitate the process
of producing water statistics, in particular the
survey design and sample weighting for
estimation
The characteristics of institutional units are well
articulated in the 2008 SNA (which is based on
country practices), however, the characteristics
of inland water resources have apparently not
been described in this way before.
Question 11 – What are the country
practices in establishing a frame, and, by
extension, the identification of the
characteristics of inland water resources?
•
This is related to the previous question as
well as to Part II Chapter VI, Data source
and methods, but is also relevant here
•
For example, to what extent are area frame
frames used for this purpose?
