MEGS Working Committee Meeting Statistics Canada
RH Coats building 7, Ottawa13 January 2012
Background
• Europe: – European Strategy for Environmental Accounting 2003/2008 includes
ecosystem accounts (under EEA responsibility)– EEA-MB/ Eurostat-DIMESA Seminar, Luxembourg, 24 November 2009: Fast
Track Implementation of Simplified Ecosystem Capital Accounts– Demand by the European Parliament for further inclusion of ecosystems in
the new environmental accounting regulation • Request from UNCEEA at its 5th meeting (June 2010) for UNSD,
World Bank and EEA to report back with a broad outline and road map for ecosystem accounts
• 6th UNCEEA meeting: endorsement of the outline and roadmap of SEEA part 2 on experimental ecosystem accounts to be presented at UNSC 2013
Policy Demand
• Europe:– GDP and Beyond process– Resource Efficiency Flagship Initiative 2020– Water Framework Directive – Environment Liability Directive of 2004– Forthcoming ecosystem assessment 2014
• International (as expressed at the UNCEEA meeting of 15-17 June 2011)– Wide range of emerging measurement/monitoring initiatives require an
ecosystems perspective of sustainability and information on the links between ecosystems and human well-being
– Millennium Ecosystem Assessment (MA) 2015 under preparation;– World Bank’s WAVES partnership– At the UNCEEA, demands by UNEP (Green Economy), OECD, CBD (Aichi-
Nagoya Strategy), FAO (SEEA Agri), the UN Coordinator of the Rio+20 Conference...
• EEA asked to deliver first (physical) accounts by MAY 2012
Simplified ecosystem capital accounts
• Make it feasible NOW – keep it simple
• Don’t miss important issues: needs a good narrative and checklist
• All ecosystems need to be addressed: land/sea/atmosphere, and for land: urban, agriculture, forest, other natural and soil.
• Basic accounts of biomass/carbon, water and landscape/biodiversity combined with diagnoses (instead of mere additions): ref. to the “ecosystem distress syndrome” approach of David J. Rapport integrated into an accounting framework
• Physical accounts first (2012), stocks, flows (natural flows and economic use), accessible surplus and integration; ecosystem capital potential/ capacity and degradation measured with a composite equivalent-unit.
• Physical accounts followed by valuation of selected ecosystem services and of ecosystem restoration costs. No valuation of ecosystem stocks.
The “fast tract implementation of ecosystem capital accounts” in Europe, based on land accounts.
Nov. 2011: publication of an experimental framework based on the EEA experience in land accounting, assessments and valuation (in particular in the context of TEEB) and the tests carried out in 2010-2011.
Characteristics of ecosystem capital accounts• Top-down approach
• Compiled at the European scale; member countries involved progressively on a voluntary basis
• Geo-referenced approach to 1) detect issues and hotspots and 2) connect global/EU to national to local scales
– 1km2 EU standard grid to integrate multiple dimensions– Small analytical functional units: “Land cover functional units”, “Socio-ecological
systems” or “socio-ecological production landscapes” or proxies…– Reporting units: countries, regions/provinces, catchments…
• Meet the policy demand: annual updates for t – 1; first time serie for 2000-2010
• Deep rooted in the best available datasets: – Socio-economic statistics – Monitoring by satellites (land use, biomass, climate variables…)– Best available in situ monitoring data
• Necessary additional estimations transparent and reproducible
• Relevance matter more than accuracy
• Measure ecosystem capital degradation
Ecosystem capital approach: narrative and practicalities
1. Narrative: an ultra-short version by 3 Japanese students
2. Narrative: additional details
3. Practicalities: focus on statistical units
1. Ultra-short story
Ecosystem capital potential (& degradation) can be measured by combining measurements of 3 ecosystem services:biomass/carbon, freshwater and systemic services
The simplified ecosystem capital accounting circuit
there is little or no compensation or tradeoff between them; the use of one should not reduce the use of the othersbiomass/carbon, freshwater are based on conventional balances systemic services (regulating, socio-cultural…) are measured indirectly in relation to ecosystem integrity.

a. Accounting for the performance(s) of 2 co-evolving systems: resources, productivity and health
b. Ecosystems deliver altogether multiple servicesc. Ecosystems deliver altogether services which are private, common and public
goodsd. Only a surplus from ecosystem services is accessible for human use e. Ecosystem capital produces altogether 3 broad types of services between which
there is little or no tradeoff: biomass/carbon AND freshwater AND functional services. Ecosystem capital potential (& degradation) can be measured by combining measurements of these 3 broad services (accessible resources).
f. Estimation of ecosystem capital depreciation can be derived from physical degradation
g. The integrated ecosystem capital frameworkh. Ecosystem Capital should not be valued as a stock; ecosystem services can be
valued one by one but are not fully additive (functional analysis)i. To address multiple scales, ecosystem capital accounts need to integrate

The narrative behind Ecosystem Capital Accounts:
c. Ecosystems deliver altogether services which are private, common or public goods
The narrative behind Ecosystem Capital Accounts:
d - Only a surplus from ecosystem services is accessible for human use
Ecoproduct (of cycling and reproductive systems/ capital) are produced by means of other ecoproducts. The ecosystem production function includes a surplus ecoproduct that can be used by the economy. (from Anthony Friend 2004)
Economy
Basic eco-product
Non-basic eco-product
Sources: Kling/U Michigan_2005 & Friend/ISEE_2004
Necessary for ecosystem reproduction (conservation of ecosystem health, integrity, functions & services)
Surplus accessible for harvest/abstraction
The narrative behind Ecosystem Capital Accounts:
d - Only a surplus from ecosystem services is accessible for human use
Basic eco-product
Non-basic eco-product
Sources: Kling/U Michigan_2005 & Friend/ISEE_2004
Possible compensation = artificial input (irrigation,
energy, fertilizers, infrastructures…)
Challenge = maximise yields while maintaining natural functions and biodiversity
Necessary for ecosystem reproduction (conservation of ecosystem health, integrity, functions & services)
Surplus accessible for harvest/abstraction
Non-sustainable harvest/abstraction Economy
Natural resource: availability, appropriation, accessibility
• Available resource: the total resource (actual stocks and flows) which can be used in principle (but should to be shared between economy and nature…).
• Appropriated resource: the share of the total potential resource flows (flows which would be available in an ecosystem in the absence of human activities or flows from managed ecosystems) which is used (abstracted, harvested or destroyed during harvest). N.B.: Once used, the resource is considered as appropriated in total, even though one part is returned to the ecosystem.
• Accessible resource: the surplus (actual stocks and flows) which can be used considering 1) physical constraints (timeliness and location, cyclical risks, bio-chemical quality) & 2) the amount to be left to nature for ecosystem reproduction. N.B.: When returned to the ecosystem (leftovers in agriculture or forestry, water returns…) the resource destroyed or modified during the production process becomes accessible again.
Ecosystem capital accounts refer to accessible resource and intensity of use.
Accessible resource: carbon/biomass, freshwater, systemic services
Accessible resource =Stocks (soil, forests, aquifers, reservoirs, landscapes…)Plus/minus change in stocks (from the previous year)Minus inaccessible stocks
Physical inaccessibility (deep aquifers …)Inappropriate quality (salted or polluted water, non arable land…)
Plus flows (NPP, effective rainfall…)Minus inaccessible flows
Physical inaccessibility (most of flood water, distance, non transportable resource, timeliness issues, water evaporated by irrigation…)
Inappropriate quality (polluted water)Maintenance of stocks (soil carbon, forests, aquifer level, dilution of
pollutants in rivers…)
Plus/minus adjustment for stress, risk
Example of accessible water adjustment: occurrence of soil water stressNumber of days when no water was available for plants in 2001, 1 km^2 grid

Theoretical units vs. observation units (proxies for collecting data)
• Theoretical units: characteristic systems into which natural and socioeconomic elements interact to transform ecosystem functions into goods and services: – Functional units producing elementary
services– “Socio-ecological systems”, “socio
ecosystems” or “Socio-ecological production landscapes” (the Japanese satoyama and satoumi)
• Observation units: – For which we can collect data in a
systematic way– Mostly surface units: “geo-systems”, land
cover units, functional administrative units, ownership units…

Conclusion: biodiversity & finance, a few questions…
• Back to the first quotation by Bertrand de Jouvenel, 1968: “Because National Accounts are based on financial transactions, they account nothing for Nature, to which we don’t owe anything in terms of payments but to which we owe everything in terms of livelihood.”
• We certainly owe nothing to Nature, but by degrading biodiversity and ecosystem don’t we create debts to future generations?
• These ecological debts don’t they come in addition to conventional debt, private and public - which will have to be repaid one day, one way or another?
• Should not the international financial and monetary system take into account(s) ecological debts, in addition to conventional debt?
• Can ecosystem capital accounts contribute to this endeavour?
