Outline

Why have environmental accounting?

• Water Accounting and the Global Water

Partnership and Integrated Water Resource

Management

SEEA Water

• development

• structure

• standard tables

• Indicators from SEEA Water

Lessons from implementation

2

Why an accounting approach?

Encourages the adoption of standards

Introduces accounting concepts to environmental statistics

Improves both economic and environmental statistics by encouraging consistency

Implicitly defines ownership and hence responsibility for environmental impacts

Encourages the development of comprehensive data sets

Facilitates international comparisons

3

Strengths of the accounting approach

Organised body of information facilitates integrated economic-environmental analysis

(complements sustainable development indicators, modelling)

Comprehensive and consistent, routinely produced

Provides a system into which monetary valuations of environmental costs can be incorporated

4

Environmental-Economic Accounting and Environment Statistics

Separate piles of information

Environment statistics:

Often developed to answer one particular question or problem

• Difficult to figure out if all information is included

• Not always easy to see the whole picture, or how it relates to other things

• Typically not integrated with economic statistics

5

Environmental-Economic Accounting builds on Environment and Economic Statistics

Integrated information

Environmental accounts:

Help to make sense of the larger picture

• Help to identify pieces that are missing

Can make connections to other statistics, especially to economic statistics

6

Terminology

Terminology is not always consistent among economists, environmental statisticians, scientists and policy makers

=> Need to use a clear, agreed terminology

One of the SEEA main contribution is the standardisation of terms and definitions

7

Keys concepts of SEEA

Stocks Flows

Volume

(e.g. tonnes, m 3 )

Value

(e.g. $, £, ¥, €)

The role and value of

Water Accounting

SEEAW provides the muchneeded conceptual framework for monitoring and assessment”

Integrated Water Resources

Management: core features

• Involves developing efficient, equitable and sustainable solutions to water and development problems

Involves aligning interests and activities that are traditionally seen as unrelated or not well coordinated

(horizontally and vertically)

Needs knowledge from various disciplines as well as insights from diverse stakeholders

Not just water: involves integrating water in overall sustainable development processes. Also requires coordinating the management of water with land and related resources

10

The challenge:

Monitoring and assessing water resources for the MDGs within an IWRM approach

Partnership

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 1 st draft SEEA Water discussed in by sub-group

(New York)

• May 2006 2 nd Draft discussed at the User-Producer

Conference (Voorburg)

Jun 2006 2 nd 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

12

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

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 water scarce countries it has been water supply and use. In industrialized countries it has been 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.
