Yet, there is a substantial gap in the understanding of how local knowledge and Indigenous knowledge are employed to respond to climate change water-induced disasters. We examine this gap through a meta-review of literature published between 2014 and 2019 yielding 39 scholarly papers. The meta-review indicates that the literature highlights that marginalized people are facing multiple risks that threaten their ability to produce enough food for consumption, secure water for irrigation, live in sustainable communities, and maintain their health and well-being. Responses are largely incremental, autonomous adjustments, such as livelihood diversification, flood-proofing homes, and soil moisture conservation. Our findings show that there is a clear need to more closely attend to the processes by which local knowledge and Indigenous knowledge can be meaningfully integrated into adaptation to move toward transformative change for long-term climate resilience.

However, while there is considerable attention devoted to migration in response to sea-level rise, there is a limited understanding of human mobility due to freshwater and inland hydroclimatic changes. Hence, the aim of this paper is to examine the existing evidence on migration as an adaptation strategy due to freshwater and inland hydroclimatic changes. A meta-review of papers published between 2014 and 2019 yielded 67 publications, the majority of which focus on a handful of countries in the Global South. Droughts, floods, extreme heat, and changes in seasonal precipitation patterns were singled out as the most common hazards triggering migration. Importantly, most of the papers discuss mobility as part of a portfolio of responses. Motivations to migrate at the household level range from survival to searching for better economic opportuniti...

It is an agricultural, recreational, historical, and cultural center where 1800km of levees protect the current land uses and prevent salinity intrusion into the freshwater supply. For decades the region has been ripe with political controversies stemming from conflicting interests over its natural resources. The threat of climate change has added a layer of urgency to understanding the mobilization of narratives at different scales. This dissertation is comprised of three distinct parts. I used the Q methodology to explore the discourses of the broad range of stakeholders about flood risk and flood management in the Delta. The results of the Q-study reveal five distinct views regarding the risk of submersion of one or more islands due to either overtopping during high waters or structural levee failures. Proximity, sense of vulnerability, values, trust, and views of climate change are the underlying factors in these perspectives. Then, using a collection of 345 newspaper articles from twelve different publications written between 1972 and 2017, I examined the trends and shifts in the narratives about floods in the Delta. Results show changes in framing over time and differences between local, regional, and national media. Lastly, I analyzed the characteristics of atmospheric rivers that have preceded floods in the Delta using MERRA-2 0.5 × 0.625 6-hourly global atmospheric river (AR) reanalysis V2.0 and details about 57 documented floods from 1980 to 2019. Results show that most of the ARs that have made landfall in the watersheds that feed the Delta are not severe. Most of the floods, however, have been preceded by strong ARs. The most recent years (1999 to 2019) have had a small number of floods, and even fewer levee failures. However, the most recent ARs that impacted the Delta made landfall in the San Joaquin watershed, not the Sacramento watershed, which was the predominant origin of the more destructive floods in the earlier decades of this study
