Monitoring chlorophyll-a concentration or turbidity is crucial for understanding and managing oligo- to mesotrophic coastal waters quality. However, mapping bio-optical components from space in such shallow settings remains challenging because of the strong interference of the complex bathymetry and various seabed colors. Correcting the total satellite reflectance signal from the seabed reflectance in ocean color with high resolution sensors is promising. This article shows how unsupervised clustering approaches can be applied to Sentinel-2 images to classify seabed colors in shallow waters of a tropical oligotrophic lagoon in New Caledonia. Data processing included Lyzenga correction for estimating the water column reflectance, optical spectra standardization for attenuating water absorption effects and clustering using the unsupervised k-means method. This methodological approach was applied on the 497, 560, 664 and 704 nm optical bands of the selected Sentinel-2 image. When applied on non-standardized data, our unsupervised classification retrieved three seafloor clusters, whereas five seafloor clusters could be retrieved using standardized data. For each of these two trials, the computed membership values explained more than 75% of the inertia in each Sentinel-2 wavelength band used for the clustering. However, the accuracy of the method was slightly improved when applied on standardized data. Confusion index mapping of the unsupervised clustering retrieved from these data emphasized the relevance and robustness of our methodological approach. Such an approach for seabed colors classification in optically complex shallow settings will be particularly helpful to improve remote sensing of biogeochemical indicators such as chlorophyll-a concentration and turbidity in fragile coastal environments.

This thesis takes an actor-oriented approach to a micropolitical analysis of the engagements of Kanak villagers in the Voh-Koné area, New Caledonia, with the Koniambo Project, a proposed joint nickel mining venture involving a multinational (Falconbridge) and a local mining company (SMSP). In the introductory chapter, I outline my theoretical framework, which expands political ecology by applying insights from micropolitical theory to a focus on intracommunity disputes surrounding natural resource exploitation projects. I argue that such a close examination is necessary if we are to understand local tensions and factions and their multiple influences on the outcomes of development projects. ¶ The Koniambo Project promises to redress some of the economic imbalances prevalent in the archipelago by benefiting the largely Kanak, and historically underprivileged, Northern Province. Thus, this mining project has great politico-economic significance, both for pro-independence leaders as well as for those who wish to maintain New Caledonia as a part of France. However, while people expected benefits for the Kanak people as a whole, the project sparked intracommunity conflicts at the local level. I argue that villagers’ claims to the right to authorize mining activities as well as their desires to receive recognition from the mining company reflected their eagerness to prove a high social position. Meanwhile, in line with the traditionally competitive political climate within Kanak communities, there were many debates about who exactly the ‘landowners’ were. Indeed, the project’s potential to disrupt or reinforce control over land – which, unlike material goods, was a socially acceptable object of overt rivalry – created unexpected socio-political stakes. These differential micropolitical possibilities shaped people’s discourses about the project’s other impacts. For instance, those who expected to be able to access employment opportunities as well as social recognition from the mining project were more inclined not to worry about the project’s consequences for natural/cultural resources. Similarly, Voh-Koné area villagers’ statements and actions regarding dangers from spirits or forbidden places were strongly influenced by their expectations of the project’s ability to strengthen or weaken their social status, as determined by their genealogies and proven through demonstrations of their relationships to their ancestors. ¶ In the final chapter, I provide a summary of my conclusions about the micropolitics behind local community members’ engagements with the Koniambo Project. Next I explain how, while this case itself is unique due to the project’s unusual politico-economic significance, the theoretical framework and methodology outlined in this thesis can help to create balanced, nuanced analyses of intracommunity diversity and micropolitical conflicts that objectively yet sympathetically portray local people as real human beings. Finally, I suggest new directions for further research on the interactions of mining companies and local communities.

D'importants développements humains et économiques sont attendus à court terme dans la zone rurale de Voh-Koné-Pouembout (Nouvelle-Calédonie) suite à l'installation d'un complexe minier, avec pour conséquence probable l'augmentation rapide et significative de la pression de pêche sur les ressources ichtyologiques. Face à cette perturbation à venir, il est nécessaire d'envisager de manière appropriée le suivi et la gestion des ressources sur le long terme. Dans un premier temps, à partir de campagnes de comptages en plongée et d'enquêtes de pêche, un état des lieux des ressources et de leurs usages est fait avant l'apparition de changements majeurs. Puis, différentes analyses ont abouti à l'identification d'indicateurs potentiels pour un suivi des ressources ichtyologiques sous impact de la pêche. Dans une optique opérationnelle, des réflexions sur la mise en oeuvre de ces indicateurs, sur l'optimisation de l'échantillonnage et sur l'intérêt de méthodes d'observation additionnelles (vidéo) ont permis de proposer des recommandations pour un suivi à long-terme des ressources ichtyologiques et des activités de pêche correspondante.
