Need to understand the building
blocks of environment and
economic statistics
• These are large fields and require
knowledge and experience to fully master
• It is possible to understand the basics
relatively quickly

Statistical Units
A statistical unit is an entity about which information is sought and for which
statistics are ultimately compiled. It is the unit at the basis of statistical aggregates
to which tabulated data refer.
These units can be divided into two categories:
(a) observation units – identifiable legal/organizational or physical entities
which are able, actually or potentially, to report data about their activities;
(b) analytical units – entities created by statisticians (also referred to as
statistical constructs), often by splitting or combining observation units in
order to compile more detailed and more homogeneous statistics than it is
possible by using data on observation units. Analytical units are not able to
report data themselves about their activities, but there exist indirect methods
of statistical estimation.

Enterprises
Definition
• An institutional unit in its capacity as a producer
of goods and services is known as an enterprise.
An enterprise is an economic transactor with
autonomy in respect of financial and investment
decision-making, as well as authority and
responsibility for allocating resources for the
production of goods and services. It may be
engaged in one or more economic activities at one
or more locations. An enterprise may be a sole
legal unit.

7
Establishments
Definition
• The establishment is defined as an enterprise or part of an
enterprise that is situated in a single location and in which
only a single productive activity is carried out or in which
the principal productive activity accounts for most of the
value added.
• In other words, an establishment can be defined, ideally, as
an economic unit that engages, under a single ownership or
control - that is, under a single legal entity – in one, or
predominantly one, kind of economic activity at a single
physical location - for example, a mine, factory or
workshop.

Industrial Classification – what is
an industry?
• An industry is a grouping of establishments
engaged in the same or similar kinds of
activities
• The classification used in national accounts
and water accounts is the International
Standard Industrial Classification (ISIC)
9
ISIC – International Standard
Industrial Classification
• Enterprises and establishments are classified using
ISIC Revision 4 according to the goods and
services they produce
http://unstats.un.org/unsd/cr/registry/default.asp
• Sometimes all establishments of an enterprise are
classified to the same ISIC code
• Sometimes establishments of the one enterprise
are classified to different ISIC classes.

National Accounts
• National Accounts aggregate the information on
the economy, obtained from the units of the
economy, into a standard format from which well
known indicators are derived
• Gross Domestic Product is the best known of the
indicators from the national accounts
• Use of international standard System of National
Accounts (SNA), classifications (e.g. ISIC) and
table formats allows for meaningful comparisons
over time and between countries
12
The environment
• The environment has 4 components
• Land
• Atmosphere (Air)
• Water
• Life (biodiversity)
• Energy, and solar energy are also important in
environment statistics
• The components of the environment interact with
each other and with the economy

Development of SEEA Water
• Sub-group on Water Accounting established at the 2003 meeting
of the London Group (Rome)
• Sep 2004 SEEA Water discussed at London Group Meeting
(Copenhagen)
• May 2005 1st draft SEEA Water discussed in by sub-group
(New York)
• May 2006 2nd Draft discussed at the User-Producer Conference
(Voorburg)
• Jun 2006 2nd Draft discussed by London Group and UNCEEA
• Jul-Dec 2006 SEEA Water finalised by electronic discussion
• More than 20 experts participated in the Sub-group
• UNSD coordinated the group and prepared the various
manuscripts
16
SEEA Water – an interim
international statistical standard
• Part 1 of SEEA Water was adopted by the United
Nations Statistical Commission in March 2007 as
an interim statistical standard
• Part 2 contains the elements of SEEA Water for
which there is less country experience and there is
still some debate
• SEEA Water has been recognized as useful by the
users of information

Indicators and policy uses of
SEEAW
Source of pressure on water resources:
• Macro trends in total water use, emissions, water
use by natural source and purpose, etc.
‘Decoupling’ economic growth and water use,
pollution
• Industry-level trends: indicators used for
environmental-economic profiles
• Technology and driving forces: water
intensity/productivity and total (domestic) water
requirements to meet final demand
• International transport of water and pollution

Key lessons from countries
implementing SEEA Water
1. Build on existing statistical/scientific knowledge and information
2. Cooperation essential
• Within statistical offices
• Between statistical offices, water departments, economic/planning
departments and agricultural departments
• With the water supply industry
• With the scientific and research communities
• Between users and producers of information
3. A phased approach is needed
• Start with issues of most importance. In general for water scarce
countries it has been water supply and use. In industrialized countries
it has been water pollution.
4. Pilot or experimental accounts are very useful
• Users will appreciate the benefits more easily with concrete examples,
even if they are small scale.

Statistics and Accounts 2006)

UNSD – current work on water
accounts and water statistics
• Developing International Recommendations for Water
Statistics
• Developing training materials
• Conducting training courses
• Assisting countries with implementation via:
• Country missions
• Telephone and email
• Work with other partners e.g. UN regional commissions and
other UN agencies, Medstat, OECD, Eurostat, World Bank,
Asian Development Bank.

International Recommendations
for Water Statistics (IRWS)
• UNSD is developing IRWS
• The IRWS will define and support the compilation of basic
statistical data to support the SEEAW and the water
indicators used by international agencies (e.g. the FAO,
World Bank and UN MDGs)
• It will provide information on the concepts, sources and
methods needed for basic water statistics
• It will also provide practical guidance on the compilation
of water accounts and indicators
• A draft of the IRWS should be available for discussion in
mid-2008.
• An expert group meeting is planned to discuss the draft
