The exact level of provision depends on local conditions and is dynamic (as some sendees can be run down if beyond natural capacity â nutrient mining). There is therefore a trade-off in the conversion with some gains and some losses, not always to the same parties. The provision responds to the existence of biological elements and man- made (fertiliser, machine input etc). The ESS relates to the contribution of the biological elements. It is important to distinguish therefore between the gross output from the land and the net contribution of the ESS. See Chapters 4 and 5 for details and Ba/mford et al (2008) for discussions on production functions and balance of natural and man-made inputs. Core Step 2: Develop and populate a matrix of ecosystem service (ESS) values across land-uses for each biome (and for each region) - in a form that allows link to the land use data. This step is described in detail in Chapter 2 and Annex 1. There are several key issues â data coverage, meaning of the data, selection of suitable cases to develop representative pictures of ecosystem service values for land use and biome and populate the ecosystem services matrix.
