Helme, Herehia. "Biodiversité anguillicole en milieu tropical insulaire (Tahiti) face aux aménagements hydroélectriques." Thesis, Paris Sciences et Lettres (ComUE), 2017. http://www.theses.fr/2017PSLEP045/document.
This thesis in fundamental and applied research has for biological model the freshwater eel which has always fascinated the world of the research by its unique cycle of life and all its mysteries not solved for some. Worldwide, 19 species of eels exist, some of which are declining in temperate zones, which may justify the increase in research in the tropics. In French Polynesia, this mysterious animal is sacred; the Polynesian legends associate the eels with the creation of life. Three species are present: the marbled eel "Anguilla marmorata", the mountain eel "Anguilla megastoma" and the eel "Anguilla obscura". They do not have the same spatial distribution where the former adapts to any medium, the second goes up the rivers to the upper valley at several hundred meters of altitude, while the latter remains in the lower valley preferring the stagnant waters. Thanks to the numerous rivers on Tahiti, this main island of Polynesia is in the midst of an energy transition and now favors renewable energies; particularly hydroelectricity. However, hydroelectric developments known to cause problems of ecological continuity of freshwater biodiversity, especially for eels, will interest us in this thesis work on the Cifre grant. It is in this context that this thesis, in the largest valley of Tahiti, is the Papenoo. Two problems are studied: the recruitment of glass eel and the study of the adult population. Our results over the three years following the arrival of juvenile eels in the mouth of the Papenoo reveal a seasonal recruitment of elvers from November to March with two peaks in December and January. More than 80% of elvers are Anguilla marmorata. For adult populations, we observe: 1/ more than 90% of the population is also Anguilla marmorata, 2/ adult eels have a density gradient from downstream to upstream, and 3/ biological continuity does not come from dams or water removal in themselves, but comes from the tailrace leaving the hydropower plant where we observe an over-attractiveness for the eels. This study proved to be very important in the theoretical advancement of our biological and ecological knowledge about the eel, in the appropriation by industry of good practices and in a solid communication on the possible coexistence between management and development

Low-lying reef islands and coastal areas of tropical mountainous islands are highly vulnerable to the impacts of tropical cyclones and the expected effects of climate change. However, while the French metropolitan coasts have benefited from a significant effort to assess their long-term changes, French overseas islands are the least documented areas in French Territory. Based on this observation, this thesis examines the respective contribution of natural and anthropogenic drivers in the past evolution of reef islands (French Polynesia) and mountainous island beaches (Northern Lesser Antilles). This study relies on a combined approach between geomatic and fieldwork. From a multi-scalar (spatial and temporal) analysis, we detect and attribute the planimetric changes experienced by the sedimentary systems of the studied islands. Results on reef islands are comparable to those of previous studies which established that most of the islands have been stable or in expansion over the last decades. They allow to suggest conceptual models of long-term trajectories and examine the respective contribution of the drivers considered in this study. On mountainous island beaches, this study shows that local settings explain the high longitudinal variability detected in various climatic situations. In addition, this study contributes to the global samples of studied islands and to move forward on the understanding of past coastal changes in French overseas islands

In the context of climate disruption leading to accelerated sea-level rise and intensified tropical cyclones, the vulnerability of coastal areas is heightened globally. Island territories are even more susceptible to these phenomena, which could challenge their development. Consequently, reinforcing their adaptive capacity is crucial.This doctoral thesis in spatial planning assesses the influence of climate change adaptation on spatial production in tropical island environments. It specifically examines the implementation of a local adaptation strategy, including spatial reconfiguration, on the scale of Martinique, a French territory in the Caribbean.The objective of this research is to anticipate the consequences of climate change on French Caribbean island territories to enhance their resilience, primarily through the renewal of land management.Our investigative approach relies on a combination of complementary methods borrowed from the social sciences: exploratory fieldwork, semi-structured interviews, discourse analysis, participant observation, documentary analysis, case studies, and cartography.With a focus on the appropriation and operationalization of our results, we delve into the tools and methods used, as well as the strategies devised and implemented by planning actors (field practices).Our findings are as follows:1° Despite numerous socio-economic and natural crises leading to spatial reconfigurations in Martinique, technicians' perception of vulnerability to sea-level rise and cyclonic swells did not prompt the development of a new planning strategy involving spatial reconfiguration in Martinique. The perception of climate change does not appear to have been a triggering factor.2° The National Integrated Coastal Zone Management Strategy 2012-2015 and then 2017-2019 establishes spatial reconfiguration as doctrine and anticipates regional implementation. Except for the emergency situation experiment in Le Prêcheur, the "soft injunction" of the NICZMS did not lead to the widespread of spatial reconfigurations in Martinique. Organizational, partnership, institutional, or political barriers were identified.3° Formulating a land strategy is essential for implementing spatial reconfiguration. However, current planning tools and methods for deployment are either non-existent, obsolete, or inadequate. Their overhaul is indispensable. Internal (evolution of actors' strategies) and external dynamics indicate that a redesign is already underway.4° In contrast to the National Integrated Coastal Zone Management Strategy, the Law of August 22, 2021, combating climate change and strengthening resilience to its effects, known as the "Climate and Resilience" Law, constitutes a "firm injunction" for spatial reconfiguration of territories impacted by coastal retreat. It modifies existing tools and methods and introduces new ones. We have formulated recommendations to address persisting gaps.5° Climate change adaptation disrupts spatial planning practices and necessitates a renewal of territorial engineering. Training, mobilization, and valorization of local expertise are essential. The training and specialization of structures supporting local actors are also crucial, as they can otherwise impede the development of adaptation strategies in coherence with island reality and encourage "maladaptations". Finally, field observation has led us to propose a new concept: "touristic consulting”
Teissier, Yoann. "Metapopulation dynamics of dengue epidemics in French Polynesia." Thesis, Sorbonne Paris Cité, 2017. http://www.theses.fr/2017USPCB008.
Dengue has been epidemic in French Polynesia for the past 35 years. Despite the relatively small population size in French Polynesia, dengue does not disappear and can persist at low levels for many years. In light of the large number of islands comprising French Polynesia, this thesis addresses the extent to which a metapopulation context may be the most appropriate to describe the epidemiology and persistence of dengue in this case. After compiling a database of dengue cases over the last 35 years, we used a number of descriptive and statistical epidemiological analyses that revealed distinct spatio-temporal disparity in dengue incidence for archipelago and islands. But the global structure of the epidemics of the same serotype were not affected. Metapopulation analyses revealed asynchronous dengue incidence among many of the islands and most notably larger islands lagged behind the smaller islands. The critical community size, which determines dengue persistence, was found to exceed even the largest island of Tahiti, suggesting that dengue can only exist by island-hopping. Incorporation of island connectedness through patterns of human migration into a mathematical model enabled a much better fit to the observed data than treating the population as a whole. The metapopulation model was able to capture to some extent the epidemic and low level transmission dynamics observed for the period of 2001-2008. Further analyses on differentiating incidence of disease and infection will likely prove informative for the metapopulation model of dengue epidemiology in French Polynesia
