SEEA-Water and IRWS Statistical standards for
water information
United Nations Statistics Division Department of Economic and Social Affairs
Outline
The International Recommendations for Water Statistics (IRWS) The System of Environmental-Economic Accounts for Water (SEEA-W) The SEEA-Water and IRWS in the context of official statistics 5th World Water Forum
International Recommendations for Water Statistics (IRWS)
Tool to develop and strengthen water information system in countries Provides agreed definitions and classifications of water data items classified • Uses a hierarchical structure Provides guidance on how to organize the data compilation Shows the link between these data items and: • Standard tables of the SEEA-W • International water indicators (e.g WWDR)
The SEEA-Water System approach to water information Presents stocks and flows of water Links the physical information to the economic accounts Shows water-related expenditures • investment in hydraulic infrastructures • fees paid by whom • costs of collection, purification, distribution and
treatment • water rights Set of standard tables
Water statistics - IRWS Often developed to address individual issues or questions
Often not easy to relate to other issues
Often not able to be integrated with economic statistics
Difficult to be sure all relevant information is included
Data items
Water accounts – SEEA-Water
Is a framework for organising data items using a system approach Organise information in terms of stocks and flows Cover the hydrological system and links it to the economy Help to make sense of the entire picture by showing the inter-relationships
Data items organised within a frame
Water statistics, accounts and audiences
Amount of data e.g. data regarding water resources, water supply and
sanitation, or economic activities and water
Information pyramid
Increasing aggregation of information
e.g. Decision makers, and the general public, managers analysts
and researchers
e.g. Managers, analysts and researchers
e.g. Researchers and others conducting detailed
analytical research
Audiences
Macro data
Micro data
Water statistics e.g. basic aggregates at the data item level, time series
Water accounts

SEEA-Water and IRWS international statistical standards SEEA-Water was adopted as an “interim” international statistical standard by the United Nations Statistical Commission (UNSC) at its 38th session in March 2007 IRWS was adopted as an international recommendations by the UNSC at its 41st session in Feb 2010 UNSC recommended their implementation in countries UNSD under the auspices of the UN Committee of Experts on Environmental-Economic Accounting is leading the implementation strategy for the SEEA-Water and IRWS in collaboration with the regional commissions and water institutions (e.g. WWAP, UN Water, SG Advisory Board on Water, etc.)
48 Countries have, or are planning, water accounts

5th World Water Forum – Topic 6.4 Data for all
The 5th World Water Forum agreed: • Lack of integrated water data to inform
decision making • Need not only physical data on quantity but
also data on quality and monetary data • Need strong legal and institutional
arrangements The SEEA-Water offers a coherent and
valuable framework to support national data collection and is an important part of the way forward”

Summary The SEEA-Water and the IRWS are supplementary publications forming the information system for water • in the context of official statistics
They constitute a tool to develop and organize water information in a coherent system Allow for integrating information from different sources also with economic information Allow for the identification of data gaps and overlaps Provide a useful tool for Integrated Water Resources Management Provide a tool for water monitoring and policy analysis not only in the water context but more broadly
