Major emphasis has been placed on NbS, that is, catchment interventions that are inspired and supported by nature and leverage natural processes and ecosystem services to contribute to the improved management of water. NbS potentially enhance water infiltration, groundwater recharge and surface storage, contribute to disaster risk reduction and can replace or complement grey  infrastructure that is often socioenvironmentally contested . Some examples include the reactivation of ancestral infiltration enhancement systems in the Peruvian Andes  , the use of erosion control structures in the Bolivian Altiplano   and the potential improvement of drinking water quality and flood risk reduction in urban areas of CSA  . Additionally, NbS in combination with ecosystem and community-based adaptation potentially generate important co-benefits, including increasing water security and the attenuation of social conflicts in Chile  , water conservation in coastal Peru  and flood protection in Guyana   . However, the evaluation of implementation success of NbS is often hampered by limited evidence on actual benefits .
