Background
Before water accounting exercise start (1998):
• un-coordinated sets of statistics dispersed in different
•
•
•
•
government institutions;
each agency producing data to meet the need of their
own users;
duplication of data collection (surveys, various studies,
inventories, monitoring);
inconsitent definitions and classifications;
low quality of the data (no surveys on households, lack
of coverage of small business, etc )

Benefits of water accounts
• Demanding tool regarding the consistency of results
•
•
•
•
•
(accounting balance sheet…) : between water resources and
their uses by economy, as well as within the hydrological and
the users systems...
By themselves, the accounts do not correct data; they
nevertheless permit to identify gaps and help in bridging them
with the help of modelling techniques and expert assessments.
Accounts make necessary to assess data sources in order to
eliminate error causes
Defining ways to reform statistics in order to solve data gaps
Providing water indicators derived from water accounts to
public, governmental bodies and international organisations
(National Strategies on Water access and sanitation, Reducing
poverty level, Conventions on water as well as on trans
boundaries water courses, etc…)
Creation of an inter institutional information network and
partnership – the Water Data Centre

Chalenges & advantages in water
accounting
The creation of the Water Data Center brings together
various sources of information on water:
• awareness of lack of consistency among the different
•
•
•
•
data sets and poor quality of data (the accounting
framework is an important tool for checks and balances)
working towards common definitions and classifications;
identification of data gaps and efforts to improve data
coverage (e.g. using various techniques can give some
examples;
many more analyses can be done with the water
accounts (combining different sources of information).
better meet users' demand.

0bjective of the WDC
• to provide the Ministry of Ecology & other
Ministries interested by water issues,
national and regional organisations, with
the information requested for policy
making
• reporting to international organisations
• informing the public

The principle of the WDC
• shared information system in which partner

•
•
organisations put their data in common and
access the common database
accepts being one of the partner organisations
in the Water Data Centre
databases supplied by the partners to the WDC
remain their property

Problems and difficulties & WDC actions
• Institutional & internal cooperation( data & database

exchange)
Lack of monitoring data & databases for state, use and
pollution of water resource
Unreliable data on the state, use and pollution of water
(quality of surveys & monitoring)
Level of computer & professional skills, use of foreign
language by staff
Organisation of informatics activities (software & code)
Psychological (work together & speak about problems…)

Unreliable data
& WDC action
(“FAO report review of world water resources by countries”, 2003)
Case:
• Quality of surveys when
compulsory for water
users
• Monitoring stations
QA/QC
• Technical status
• Frequency of samples
• Representativeness of placement
• Recognition of existence
of data quality problems
• Responsibility for data
reporting
International Work Session on Water Statistics

Solution:
• Combine data selective
survey + sampling

• Standardize water
definitions
• Unique codification
• Use of WDC/ NOPOLU type
integrated applications
• Water accounts

WDC needs organizing training in
computer and professional skills
• one third need special training in environment statistics,
•
•
•
•
in particular methodologies linked to water statistics:
data collection, sampling & modeling, indicators and
indexes;
one third mentioned their working places are not
arranged with computers;
majority indicated software packages such as MapInfo
and Access as unknown or unused;
One quarter knew about the existing database on water
& they had no access & no possibility to use in reporting;
10% indicated did not know how to operate databases.

A quick example that it is important to produce
and to publish reliable data can be found from the
website http://www.gapminder.org/: “in Moldova
92% population have access to safe drink water”.
International Work Session on Water Statistics
UBA Vienna, Austria, 20 June – 22 June 2005
Dr. Jana Tafi & WDC team
According to the last statement of the Ministry of
Health in Moldova, 44% of population or 1,8
million people have no access to safe drinking
water (22 March 2005).
Cross-checking and integrating data and
statistics in Water Accounts should help in
avoiding wrong assessments and sending wrong
messages to the government, international
organizations and the public
