Pendant la deuxième moitié du vingtième siècle, les régions du Pacifique, et notamment l’Australie et la Nouvelle-Zélande, ont vu augmenter les mouvements de migrations. Ces derniers ont permis une diversification des concepts de nationalité, d’identité, de langage et d’espace. De ce fait, bon nombre d’auteurs ont donc décidé d’approcher leurs écrits à travers le spectre du transnationalisme et ont cherché à repousser les limites culturelles et les frontières géographiques -imposées par un état colonial.- Par conséquent, c’est avec une approche comparative que j’analyserai, en tenant ainsi compte de la constante évolution des nouveaux cadres géographiques et culturels, le recueil de poèmes Star Waka (1999) de l’auteur maori Robert Sullivan, le roman graphique Night Fisher (2005) de l’artiste hawaiien R. Kikuo Johnson et le roman Carpentaria de l’autrice waanyi Alexis Wright. En effet, j’examinerai la formation des identités autochtones en lien avec le lieu natal respectif de chaque auteur tout en tenant compte de l’évolution de la notion de frontière, qu’elle soit locale ou nationale. En se détournant de la perspective coloniale, je mettrai ainsi en lumière les différents outils que les auteurs utilisent dans leurs oeuvres pour permettre de définir une ou plusieurs identité(s) autochtone(s) qui se lisent entre les lignes et au-delà des limites spatiales. La question de l’enracinement et du déplacement est au coeur de ce réseau d’alliances autochtones, et permet une approche et une lecture transnationales, ainsi qu’une vision d’un monde littéraire commun et partagé. Ce réseau va au-delà des frontières locales et nationales, créant ainsi des géographies alternatives. / The second part of the twentieth century saw movements of migration increased, notably in Australia, New Zealand, and the Pacific regions, resulting in a diversification of the concepts of nationhood, identity, language, and space. As such, many authors have worked through the lens of transnationalism and have sought to think beyond the concept of borders, since locality is ultimately attached to a specific identity. Thus, to account for shifting geographical and cultural frameworks, I aim to paint a cross-cultural comparison within different genres of Indigenous literatures in Oceania. Through an analysis of Robert T. Sullivan’s Star Waka (1999), R. Kikuo Johnson’s Night Fisher (2005), and Alexis Wright’s Carpentaria (2006), I examine the formation of Indigenous identities in relation to the authors’ respective homelands while also interacting with the changing concepts of local and national boundaries. By decentering the Western definition of the border I highlight the way in which these authors can be read through the semantic lines of their works as well as across geographical borders, thereby challenging the dichotomy between the local and the global by disorientating and regenerating creative Indigenous identities on a larger scale. As the twenty-first century engages with new sorts of narratives, the issue of rootedness and displacement within a network of Indigenous alliances allows for a comparative and transnational approach, and a vision of a shared literary world that crosses over local and national boundaries, thereby enabling alternative geographies and accounting for contrasting perceptions of the world.

In an ever-moving world, urban governance and infrastructure have to adapt to climate change. In the meantime, people's concerns and engagement towards urban projects which will affect their lives are growing. The climate change adaptation process is inevitable to implement, considering the multiplicity of climate change threats. Hawai'i is no exception, and it has to adapt its infrastructures to stronger and more frequent floods. This master's thesis highlights the case of the Ala Wai risk flood management plan in Hawai'i, the U.S., and the engagement of some Hawaiians in the Protect Our Ala Wai Watershed (POAWW) grassroots movement against the proposed project. The conflict creates the emergence of two paradigms, which are translating two opposing strategies of action. Each paradigm aligns with a specific approach that reflects the interests and value systems of the individuals that constituted it. On the one hand, there is the economic growth paradigm supported by the United States Army Corps of Engineers (USACE), which manages the project and unfolds the resilience strategy by protecting Honolulu's dominant economic interests. On the other hand, there is the environmental justice paradigm, mobilized by the POAWW grassroots movement. This latter one is positioned within the transition strategy and demands the integration of indigenous knowledge into the project. To go beyond this conflictual standoff, the master's thesis argues that a hybrid paradigm, which would move towards a transformation strategy, would be preferable to surpass the current cleavages. This paradigm shift gives keys of actions and could be transferable in a contextualized way to other urban conflicts linked with the climate change adaptation process.
