The article analyzes the state of the Green Infrastructure issue in Spain, first defining what we understand by this concept and what its functions are. Second, it identifies the antecedents in different regulations, planning instruments and official technical documentation that have been developed in recent decades in Europe and specifically in Spain. This review leads to defining its current situation, establishing the current European and Spanish regulatory frameworks, as well as the one currently under development. After this analysis, it addresses the usefulness of the ecological restoration of river systems in the new context of Green Infrastructure, studying its potential as a tool for landscape regeneration, how it does it and what results it offers. To do this, we present some cases of good practices showing different forms of action at local, regional and international level that this framework of action offers.
