Ecosystem accounting Payment for specific ecosystem services vs. payment for maintaining/restoring ecosystem potential of delivering multiple services Contribution of ecosystem accounting to IPES Outline
Land & ecosystem accounts are present in SEEA2003 (the UN system of economic environmental accounts) but not fully developed Implementation of land and ecosystem accounts in Europe: Land accounts 1990-2000 [2006], 24 countries; ongoing update for 2006 and 35 countrries; tests out of Europe [e.g. Burkina Faso 1992-2002]; Ecosystem accounts: ongoing tests [e.g. for Mediterranean Wetlands in the context of TEEB] Land and ecosystem accounts planned to be developed in SEEA2012/2013 revision Ecosystem accounting
Purpose of ecosystem accounting • macro-ecological closure of the SNA-SEEA [ecosystem impacts from pressures, non linear feedbacks to the economy...] • give responses to 4 basic issues: • sustainable use of the ecosystem natural capital [stocks, integrity, resilience] => accounts in physical units, diagnosis, multicriteria rating • amortization of the ecosystem natural capital: this capital consumption is not currently recorded in corporate as well as national accounts => accounts in monetary units, full cost of domestic products • concealed ecosystem capital consumption in imports & exports => accounts in monetary accounts, full cost of imports, full value of exports • individual and collective final consumption of non market ecosystem services which should be included in order to reflect more correctly final consumption contribution to human well being => inclusive final consumption
Ecosystem Accounts, SEEA2003 & SNA Impacts to the ecosystem SNA sectors flows products assets Sector accounts of flows of ecosystem services • Core accounts of assets & flows • systems [land systems, rivers, soil, sea, atmosphere... • components: biomass, water, C, N, P, species... Material/energy flows [biomass, water, nutrients, residuals, physical units] Supply & use of ecosystem services by sectors, I-O analysis, NAMEA Functional Ecosystem Services [Marketed & Non-market end use ES (physical units and €)] by Ecosystem types Counts of ecosystem integrity/health (focus on vigor, robustness, resilience, dependance from inputs, healthy populations & stress) • Natural capital • Natural capital stocks, health/resilience, distance to objective (physical units, by sectors) • Ecosystem capital consumption/maintenance costs (€) • Ecosystem capital consumption concealed in imports/exports (€) • NPV or market value of selected assets, SNA rules (€) • Ecosystem assets inclusive wealth (€) Ecosystem Rating & Aggregates Sector accounts of ecosystem natural capital Feedbacks to the economy

Note: the following points owe to Graciela Chichilnisky [1995, 2000, 2008...] and to the discussions initiated by the UNEP-IPES group. They are interpreted here in the context of accounting - “traduttore, tradittore” ? although its components [natural resource] can be private, the global ecosystem is a public good with a potential of delivering a bundle of services: beyond the economic resource, ecosystems reproduce the resource itself as well as present and future regulating and cultural ecosystem services [often not accounted] in absence of well defined private and public property rights regimes, ecosystems are facing “the tragedy of the commons” this is particularly at work in the imbalanced North-South trade, where de facto open access to natural ressources in the South have generated ecosystem degradation [in addition to climate change], poverty – as well as distorsions in production and consumption patterns in the North. property rights should be established on the usage of the public good [output side], not on the resource components [input side] Rationale of global trade of ecosystem permits [1]
the need to maintain [& restore] ecosystem functions is broadly aknowledged in international and national law: e.g. CBD, conventions for managing transboundary catchments, adaptability to CC, European Environmental Liability Directive [2004], mitigation banking schemes [US-wetlands, several countries in Europe...] - quantified targets can be established a “cap and trade”mechanism could be put in place for the ecosystems in general, in the same way as the global carbon permit mechanism in the case of atmosphere. “cap” can be fixed in reference to stated international objectives “trade” can be related to the gap between observed ecosysem state and officially stated objectives [distance to target] = related to ecosystem natural capital consumption Rationale of global trade of ecosystem permits [2]
the ecosystems cannot be maintained identical for ever; human developement requires resource, space; the opportunity cost of maintaining an ecosystem may be much higher than the sum total of the services it delivers => the maintenance or restoration is that of a potential for delivering services; compensation, mitigation not at the same place; in some cases, no compensation is possible [e.g. unique ecosystems, nodes or major corridors in ecological networks...] => strong legal protection needed in addition to trading [same as for public health and protection of consumers]; what about equity? => rights to use a public good = “no rival consumption”, efficiency depends on equity [contrarily to private goods] ecosystem, biodiversity descriptors are too complex for organising a global market in the same way as for C/CO2 => Correct; exchanges need a simple, abstract common measurement scale, a numeraire [in the same way, C is the numeraire use for the usage of the atmosphere re-climate degradation] Objections & tentative responses ...
Markets need accounts, regulations [= control] Land ecosystems are spatially distributed => grid data [e.g. 1 km2] Globally, change matters [degradation or improvement of ecosystem functioning and attached cost], not the value of the stock Global multicriteria rating based on a small number of ecological potential [derived from ecosystem accounts]: Landscape ecological potential [LEP] HANPP Biodiversity rarefaction Exergy loss [river basins] Dependance from external inputs [material/energy, footprint] losses/gains of “points of ecological potential” computation of restoration costs [needed for compensating losses // or accumulated by gains of points] Rating can be detailed as necessary for the policy [national, regional] and action scales [local, business] Simplified ecosystem accounts to support IPES
