Linking geodiversity and geosystem services to human well-being for the sustainable utilization of the subsurface and the urban environment.

Abstract

Because the functions of the subsurface are hidden from view, its important role in society is often ignored or taken for granted. The subsurface is, however, an essential part of the global ecosystem with important contributions to human well-being. Geodiversity is an important characteristic in this respect. Material supply is the more obvious role of the subsurface with projections of a doubling of global material use in 2060 as compared to 2017. Moreover, creating underground spaces and infrastructure are gaining importance in the urban environment. The main reason for the inadequate protection of geodiversity is the lack of a comprehensive and integrative framework. Linking socio-economic activities to biophysical system characteristics of the subsurface is facilitated by the geosystem services approach. Sustainable urban development strategies require including geodiversity in decision-making on human well-being and setting conditions for land use change. Spatial plans and decisions on the use of natural endowments should look at processes over much longer timeframes. In this paper, we explore the links between human well-being and the subsurface with an emphasis on the role of geodiversity. We set out a methodological framework and describe possible long term three-dimensional land use planning consequences for sustainable utilization of the subsurface.
