Cette thèse examine la façon dont les villageois de la lagune de Lau rurale, dans la province de Malaita, aux îles Salomon, font l'expérience de l'usage des téléphones portables. J'examine l'impact réciproque exercé par la technologie de téléphonie mobile récemment adoptée vis-à-vis des technologies de l'information et de la communication (TIC) déjà en vigueur localement. Je m'interroge également sur l'incidence que la place marginale de Lau dans l'économie capitaliste peut avoir sur l'adoption et l'usage des téléphones portables. En outre, j'analyse les principales controverses locales autour de l'adoption et de l'utilisation des téléphones portables, la conceptualisation par les indigènes du fonctionnement des technologies numériques, la moralité associée aux téléphones portables ; j'explore enfin ce pour quoi ils sont et/ou ne sont pas destinés à être utilisés. Je me concentre ainsi sur les deux fonctions principales des téléphones portables à Gwou'ulu : d'un côté, on les emploie comme des téléphones, et de l'autre comme des dispositifs pour visionner des films. En 2014, sur environ 250 adultes habitant à Gwou'ulu, 100 possédaient un téléphone portable à titre individuel, et un plus grand nombre de villageois partageait l'usage de téléphones portables avec d'autres.Mon approche théorique approfondit l'analyse technographique permettant d'étudier les technologies numériques et la consommation des médias numériques. La technographie (c'est-à-dire l'ethnographie des technologies) est une approche pluridisciplinaire qui combine l'étude des conditions historiques, économiques, politiques, religieuses, environnementales et matérielles constituant les possibilités qui à la fois limitent et facilitent les choix des individus lors de l'adoption de nouvelles technologies, y compris les téléphones portables. Mon analyse se fonde sur l'observation participante et sur des entretiens semi-directifs menés avec les locaux et centrés sur la question de leur utilisation des téléphones portables.Les conclusions de ma recherche démontrent que la vie au village se situe dans une période de transition sociale et s'achemine vers une nouvelle forme de numérisation technologique. Ma thèse souligne comment, dans la lagune de Lau, les téléphones portables transforment les TIC d'un secteur public à un secteur privé. Elle démontre aussi qu'un usage largement individualisé des téléphones portables nourrit les incertitudes locales relatives à la façon dont les téléphones portables, en tant que téléphones et que dispositifs permettant de visionner des films, contribuent à transformer les relations sociales à la fois au sein du village et entre les villageois et leurs proches installés en ville. J'avance l'idée que les téléphones portables et leurs diverses fonctions (de la télévision à la calculatrice de poche) sont mieux décrits comme des objets super-composés, parce que les téléphones portables embrassent et troublent un grand nombre de relations sociales et de valeurs culturelles qui sont les caractéristiques déterminantes d'un groupe donné dans un lieu donné. / This thesis explores the experiences of villagers in the rural Lau Lagoon, Malaita Province, Solomon Islands, as they adopt mobile phones. I discuss how the adoption of mobile phone technology affects and is affected by existing information-communication technologies; how and to what extent Lau adoption of mobile phones is circumscribed by the marginal place of the Lau in globalized capitalist economies; and I elaborate on the main controversies that surround the adoption and use of mobile phones, local conceptualizations of how digital technologies work, their morality, what they are meant to be used for and for what they are not to be used. Specifically, I focus on the two primary functions of mobile phones in Gwou’ulu: the mobile phone as (1) telephone and (2) as movie-watching device. Theoretically, I rework approaches to technography for an investigation of digital technology and media consumption with a focus on mobile phones—in 2014 of the approximate 250 adults living in Gwou’ulu, 100 owned a personal mobile phone and many more shared a mobile phone. Technography, or ethnographies of technology, offers a strategic multi-disciplinary combination that examines the historical, economic, political, religious, environmental and material conditions that constitute the realm of possibilities that constrain but also facilitate particular sets of choices made by individuals in response to the adoption of new technologies such as mobile phones. My methods for data collection are a combination of participant observation and open ended interviews on individual mobile phone usage. My findings show village life in a transition period of technological and social digitization. They highlight how, in the Lau Lagoon, mobile phones shift information-communication technologies (ICTs) from the public to the private realm and how an individualized consumption of mobile phones fuels uncertainties as to if and how mobile phones, as telephone or as movie-watching devices, transform social relationships among village residents as well as relationships between villagers and their urban relatives. I argue that mobile phones and their diverse functions—from telephony to movie player to calculator—are best described as super-compositional objects because they encompass and agitate so many of the social relationships and cultural values that are otherwise the defining features of a particular group of peoples in a particular place.

This thesis concentrates on the Kwara'ae people of a peri-urban settlement named Gilbert Camp. Originally from Malaita (hom), they migrate and settle in Honiara, capital city of Solomon Islands. They articulate their condition in relation to two sets of value oppositions. The first opposes hom as their primitive, isolated, and hopeless province of origin; and Honiara as the modern, all-promising, all-fulfilling arrival city. The second juxtaposes hom as the epitome of unity, cooperation, and sameness, where life is easy; and Honiara as the place where diversity, competition, and separation reign, and life is hard. The Kwara'ae people leave hom and settle in Honiara because they value what lacks in the former and can be found in the latter. But in Honiara they despise some of the things they must confront, and miss what they can have at hom but not in Honiara. For these reasons, they repeatedly declare, "Honiara is hard" (Honiara hemi had). However, rather than interpreting their statements about life in town as the symptom of a negative evaluation, I try to capture the extent to which the Kwara'ae people of Gilbert Camp value their urban life in a positive way. The starkest illustration of their commitment to town life is in their daily efforts to deal with the tensions over the meaning and use of their values in the urban context. I analyse these tensions, challenges, and negotiations in a series of ethnographically grounded case studies. In a peri-urban village of a shrinking Pacific economy where there is a general disproportion between income and mouths to feed, a tension between the priorities of kinship and the need to make ends meet is almost inevitable. Secondly, the confusion surrounding the issue of land causes tensions concerning how land must be dealt with. There is also a tension between customary and state law, and between historical and recent forms of Christianity. Kwara'ae people use their creativity and cultural knowledge to find viable solutions to these tensions, which I argue is an illustration of how much they try to live according to their values on the outskirts of Honiara. It follows that the statement "Honiara is hard" indicates the measure of their efforts, of how intensely they want to live in Honiara according to their values, rather than the measure of how much they want to go back hom. This interpretation has important implications for the anthropology of urban Melanesia. Previous urban ethnographies in Solomon Islands emphasised the reproduction of hom values, rather than the creation of a new hom through the manipulation of contemporary cultural logics. Although the former approach coheres with negative evaluations of the urban context, it does not account for why people leave a place where life is "easy", and settle in a place where it is "hard". In contrast, an approach emphasising the hom-making process inherent in daily value negotiations reveals the contingent, unpredictable, and contested construction of the sense of homeliness with which Kwara'ae people are turning Gilbert Camp into their new hom.

The goal of agricultural training is the adoption and diffusion of introduced agriculture techniques. New subsistence agricultural techniques have been introduced mainly to the male population in many developing countries, even though most subsistence farmers are women. Therefore, an understanding of how new subsistence agricultural techniques can be introduced and adopted by women would be important to achieve. This study focuses on women's adoption of agricultural techniques. It takes place on the island of Malaita, in the Solomon Islands. The study looks at the adoption of agroforestry and several other subsistence techniques that were introduced under a joint program by Peace Corps and the Malaita Agriculture Division between 1983 and 1989. Two Peace Corps volunteers were posted in North Malaita at Malu'u from 1983 to 1986. The Malu'u volunteers lived in the village of Karu for two and one-half years while introducing and teaching new agricultural practices. Two other Peace Corps volunteers were posted at the Dala Agricultural Training Center from 1987 to 1989, and worked with the residents of the nearby village of Kakara. In 1991, a two-month survey was conducted in the areas where the Peace Corps volunteers were posted, as well as in an area that did not have any Peace Corps volunteers posted. The findings of this study indicate that adoption of new agroforestry techniques is based on several factors. Who introduced the technology, the farmer's wealth, and being able to obtain income from market vegetables and other identified factors improved a respondent's chances of adopting new agroforestry techniques.
