Sentences with phrase «appropriate land boundaries»

Not exact matches

It has been suggested that a top - down allocation approach is more appropriate for boundaries where human activities exert a direct impact on the Earth (that is, climate change, ocean acidification, ozone depletion and chemical pollution), while a multiscale approach is more appropriate for boundaries that are spatially heterogeneous (that is biogeochemical flows, freshwater use, land - system change, biodiversity loss and aerosol loading).8 Even with a top - down approach and a single global boundary, however, allocation is fraught with difficult ethical issues.
