Worldwide interest for ecosystem services Example: the Australian Ecosystem Services Project http://www.ecosystemservicesproject.org/index.htm
SWOT • Strong point: economists speaking biology + biologists speaking economy have a chance to attract the attention of policy makers – see the impact of TEEB • Weak point: definitions still a bit loose, classifications not enough standardised • Opportunity: establish an consensus on a core common international classification to be used in the various programmes (MA, TEEB, GEI, SEEA, IW research, National assessments, Corporate/business accounting…) + establish a “system of classifiers” (classification system) for multiple purposes • Threat: multiplication of ad hoc classifications impairing comparability, aggregation…
Threats: Examples of “variants” of the classical MA classification which may lead to inconsistencies…
Wikipedia: 4+1 • Provisioning services • • foods (including seafood and game) and spices • • precursors to pharmaceutical and industrial products • • energy (hydropower, biomass fuels) • Regulating services • • carbon sequestration and climate regulation • • waste decomposition and detoxification • • nutrient dispersal and cycling • Supporting services • • purification of water and • • crop pollination and seed dispersal • • pest and disease control • Cultural services • • cultural, intellectual and spiritual inspiration • • recreational experiences (including ecotourism) • • scientific discovery • Preserving services • • genetic and species diversity for future use • • accounting for uncertainty • • protection of options
At the same time, improvements are legitimate… • Clarifications needed • Connect to international standards where relevant (products, trade) • Fit specific purposes • Scales perspectives

The way forward • Build up on existing achievements from the pioneering lists (Daily, De Groot Costanza et al…) to MA conceptual model and classification • Do quickly, if needed some marginal adjustments or clarifications in order to come to a consensus on a working core common classification • Plan a revision of the classification at the end of the MA2015 process for taking stock of new experiences • Open a research agenda for defining/developing a classification system for guiding on purpose classifications – 1 year needed CICES: Common International Classification of Ecosystem Services
