The aim of this Deliverable is to report on the use of the Common International Classification of Ecosystem Services (CICES) to characterise the biophysical, social and economic methods of ecosystem assessments, and to identify how it can be further developed to support the needs of the user community.
A first draft of this Deliverable was made available in 2016 and used to shape discussion in the various ESMERALDA workshops that took place during 2016-17. The objective of these meetings was to test a first version of the methodology for mapping and assessment of ecosystem services, and so close engagement with this work was necessary to ensure that the development and use of CICES was eventually integrated into the wider outcomes of ESMERALDA. This final Deliverable, prepared at the end of the Project, now describes both the preliminary work and the further developments that have taken place.
CICES V4.3 was developed in the context of work on the revision of the System of Environmental and Economic Accounting (SEEA) that is being led by the United Nations Statistical Division (UNSD). However, it has also been used widely in ecosystem services research for designing indicators, mapping and for valuation. In the EU, it is being used as the basis of the mapping work that is being done in support of Action 5 of the EU Biodiversity Strategy to 2020, under the MAES Programme.
This report describes the structure and conceptual underpinning of CICES V4.3, and reviews the challenges that arise in designing a classification system of this kind. These challenges include the problem of scope, the extent to which ‘final ecosystem services’ can be defined operationally, and how benefits and uses of services can be distinguished from services so that assessments can be based on sound quantitative data. The review of CICES draws on a review of the published literature and a survey of users. The conclusions drawn from this review were both extended and tested through two workshops with the user community in 2016.
The results of our work show that there is an extensive and established user base for CICES V4.3, and that it has a number of advantages for users in terms of its hierarchical structure, logic and coverage, as well as the potential it offers as a standard. The review has identified some shortcomings, however, many of which can be overcome by the development of guidelines and the provision of examples of different applications. These shortcomings, nevertheless, also point to the need to revise the present structure of the Classification, especially in the area of cultural ecosystem services.
A systematic review of the wider ecosystem service literature has provided further insights into the ways in which CICES might be improved. This work has looked at whether the CICES classes are to narrow or too broad, and whether there is a need to provide better guidance at sub-class (Class-type level). Taken in conjunction with the other work discussed here, the review demonstrates that CICES V4.3 could nevertheless serve as an effective indicator framework, and that this function should also be supported in any revision.
On the basis of the work done in ESMERALDA and in the wider user community, CICES V4.3 has been revised during 2017 on the basis of parallel work supported by the European Environment Agency. The outcome of the revision process (Version 5.1) are described also here together with the implications for ESMERALDA with its focus on the role of mapping in integrated assessment. The key recommendations we make are:
• That just as V4.3 of CICES has been tested for its coverage and completeness, effort should now be made to critically examine the structure of the new CICES version V5.1.
• The extent to which CICES 5.1 can support the clear description of the way ecosystem services are defined and measured should be examined and its use as a reference system based on concept matching techniques further explored.
• That the CICES 5.1 ‘indicator’ and ‘methods’ library developed out of the work done in ESMERALDA should be published and used to facilitate the transfer of knowledge within the context of the MAES Process.
• That future work should look at how CICES 5.1 can link to the ways we classify and characterise the condition of ecosystems, so that we can better understand the biophysical underpinnings of ecosystem services.
• Future work should also look at the way we describe and classify benefits and beneficiaries, so that we can better document how people depend on or engage with nature over space and time.
• That the relationship between CICES V5.1 and other classification systems is tested and its reference function developed further.
