            As a third item, certain environmental activities, like protection expenditures,
            are included in the SEEA-2012-CF.
                However,  accounting  for  degradation  and  other  measurement  topics
            associated with ecosystems are not covered in the SEEA-central framework
            (SEEA-CF, 2012, p. ix). Excluded as well are oceans and the atmosphere, due to
            their magnitude. Full valuation of assets and flows related to natural resources
            and land beyond the valuation included in the SNA remains an outstanding
            issue  (SEEA-CF,  2012,  p.  viii).  Basically  the  SEEA-2012-CF  focusses  on  the
            material benefits from the direct use of environmental assets or natural inputs
            for the economy by enterprises and households. By contrast, this does not
            cover the non-material benefits from the indirect use of environmental assets,
            like benefits from ecosystems services (SEEA-CF, 2012, p.13).

            2.  Ecosystem services and assets
            2.1 Conceptual approach
                 A  more  comprehensive  and  growing  approach  to  look  at  the  role  of
            nature for sustainable economic growth and human well-being is based on
                                                       2
            the concept of ecosystem services and assets . In general terms the idea is that
            ecosystems (ES) provide benefits to humanity free of charge, which have a
            fundamental importance for human well-being, health, livelihood and survival.
            (MA, 2005; TEEB, 2010). Often-quoted ES-examples are cleaning of air and
            water, wild food and crops, natural medicines, but also pollination, climate
            regulation,  filtration  of  pollutants  by  wetlands,  recreation  facilities,  soil
            formation and photosynthesis or biodiversity (MA 2005, TEEB 2010, p. 7). The
            amount of benefits provided to human societies usually depends on the type
            and quality of the ecosystem considered and hence may vary from one region
            to another. The spatial perspective therefore is a fundamental element of the
            ES-concept.
                 The ES-approach goes a step further and looks at the natural processes
            from an economic viewpoint. Like in the SNA, a distinction is made between
            flows,  which  are  measured  over  a  period  of  time  and  stocks,  which  are
            captured at a certain point in time:
                -   The  benefits  provided  by  ecosystems  to  human  societies  are
                    interpreted  as  services,  in  this  case  ecosystem  services.  The  natural
                    processes from which the ES services are resulting are looked at as a
                                             3
                    kind of production activity.
                -   On the other hand, the ecosystem capacity is considered as an asset,
                    sometimes called natural capital. The ES capacity may be negatively or

            2   The  experimental  methodology  for  ecosystem  accounting  has  been  published  separately
            (SEEA-CF, 2012).
              However, in the case of economic services their production is adjusted to demand, which
            3
            seems different for ES-services.
