Most barriers to advance adaptation in CSA correspond to soft limits associated with missing links of science-society-policy processes, institutional fragilities, pronounced hierarchies, unequal power relations and top-down water governance regimes . One example is the abandonment of long-term hydrological monitoring sites within tropical Andean ecosystems  in Venezuela  due to the lack of governmental support during the political crisis. In that regard, the collection and availability of consistent hydroclimatic and socioeconomic data at adequate scales represent an important challenge in CSA. Major adaptation barriers are furthermore reported from central Chile in the context of a mega-drought since 2010, related to socioeconomic factors and a deficient bottom-up approach to informing and developing public policy . These gaps could be bridged by strengthening transdisciplinary approaches at the science-
