MEGS Working Committee Meeting Statistics Canada RH Coats building 7, Ottawa 13 January 2012 Development and Implementation of Simplified Ecosystem Capital Accounts by the European Environment Agency Jean-Louis Weber Special Adviser to Economic Environmental Accounting European Environmnent Agency jean-louis.weber@eea.europa.eu
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 • Narrative: an ultra-short version by 3 Japanese students • Narrative: additional details • Practicalities: focus on statistical units
The background of Ecosystem Capital Accounts: Ecosystem capital potential (& degradation) can be measured by combining measurements of 3 ecosystem services: biomass/carbon, freshwater and systemic services carbon there is little or no compensation or tradeoff between them; the use of one should not reduce the use of the others biomass/carbon, freshwater are based on conventional balances systemic services (regulating, socio-cultural…) are measured indirectly in relation to ecosystem integrity. systemic services water The simplified ecosystem capital accounting circuit Ecosystem capital depreciation Ecological debts Calculating economic aggregate Healthy ecosystem benefit Adapted from Aoyama Yukiko, Oguro Michio, and Yano Tohru, Tohoku University, Sendai,Japan, November 2011 Ecosystem degradation

2. More detailed narrative • Accounting for the performance(s) of 2 co-evolving systems: resources, productivity and health • Ecosystems deliver altogether multiple services • Ecosystems deliver altogether services which are private, common and public goods • Only a surplus from ecosystem services is accessible for human use • 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). • Estimation of ecosystem capital depreciation can be derived from physical degradation • The integrated ecosystem capital framework • Ecosystem Capital should not be valued as a stock; ecosystem services can be valued one by one but are not fully additive (functional analysis) • To address multiple scales, ecosystem capital accounts need to integrate geographical information
The narrative behind Ecosystem Capital Accounts:a. Accounting for the performance(s) of 2 co-evolving systems: resources, productivity and health Economic system Economy performance Economic growth Trade Value-added, income, profit… Consumption Investment Wealth (non-financial and financial assets) Economic health (net savings, assets and debt quality, accountability, prices, well-being, knowledge) Use of natural resources Products & economic assets Fossil energy & materials Biomass/carbon Water Land functional services Ecosystem Ecosystem potential (capacity to deliver services) Ecosystem productivity Flows Accumulation Stocks Ecosystem health (biodiversity, integrity, resilience, interdependence) Capital maintenance (to remediate degradation)

Services valuation, payments for services 2 - Non valued services: mostly common goods, tradable, transferable rights 1 – ES incorporated into commodities & economic assets: mostly private goods, market prices Provisioning services Regulating services Recreating services Payments for restoring ecosystem potential 3 – Ecosystem good state: health, sustainable capacity of delivering services, life-support functions, Public Good: non-rival, non-exclusive use, non-transferable rights, taxes or lease with covenants are possible Jean-Louis Weber, CBD Conférence, Libreville, 16 Septembre 2010
Non-basic eco-product Surplus accessible for harvest/abstraction Basic eco-product Necessary for ecosystem reproduction (conservation of ecosystem health, integrity, functions & services) 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 Sources: Kling/U Michigan_2005 & Friend/ISEE_2004
Non-basic eco-product Basic eco-product The narrative behind Ecosystem Capital Accounts: d - Only a surplus from ecosystem services is accessible for human use Challenge = maximise yields while maintaining natural functions and biodiversity Possible compensation = artificial input (irrigation, energy, fertilizers, infrastructures…) Surplus accessible for harvest/abstraction Economy Necessary for ecosystem reproduction (conservation of ecosystem health, integrity, functions & services) Non-sustainable harvest/abstraction Sources: Kling/U Michigan_2005 & Friend/ISEE_2004
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

The narrative behind Ecosystem Capital Accounts: e. Ecosystem capital produces altogether 3 broad types of services between which there is no compensation or tradeoff: biomass/carbon AND freshwater AND systemic services. Ecosystem capital potential (& degradation) can be measured by combining measurements of these 3 broad services (accessible resources). Accessible carbon surplus Ecological debts in physical units Total Ecosystem Capital Potential/Capacity & Ecosystem Capital Improvement/Degradation Accessible ecosystem functional services Accessible water surplus Depreciation (money) & adjustments
