This chapter extensively presents the functionality of freshwater ecosystems, surface, groundwater and ice caps, that is inseparably linked to the ecosystem services provided by freshwater bodies and their importance for human and nature well-being. The ecosystem services provided by freshwater are of vital importance for supporting all life cycles, social processes and economic prosperity.
AbstractFreshwater ecosystems, whether surface, groundwater or in the form of ice caps are fundamental for human life and for supporting the vast biodiversity, natural processes and cycling. They provide ecosystem services, thus, benefits for humans and their societies obtained from nature, in all four categories: provisioning, regulating, cultural and supporting. The importance of sustaining ecosystem integrity via protecting the ecosystem services, is undeniable. However, it comprises a big challenge provided the human-induced degradation of the natural environment that, in turn, affects the earth's natural capital: natural resources, associated services with the supporting processes.
