Cette recherche a porté sur quelques enjeux importants liés à la gestion des aires marines protégées (AMP) en Indonésie en examinant comment celles-ci sont en mesure d'adapter leurs politiques afin de mieux répondre à l'évolution des conditions socioéconomiques et écologiques, quels ont été les impacts socioéconomiques de ces aires, et quelles sont les préoccupations environnementales des acteurs locaux dont les moyens de subsistance dépendent des ressources règlementées. Le «livelihoods framework » a servi de guide pour notre analyse des changements socioéconomiques dans la région, tandis que la notion d’« environmentality » d’Agrawal a fourni les bases théoriques pour l'examen de la formation de sujets environnementaux au parc national de Karimunjawa. Cette étude a montré que les changements de politique apportés au plan de la gestion du parc sont un pas dans la bonne direction, mais que les objectifs importants liés sa cogestion n'ont jamais été entièrement réalisés dans la pratique. Les résultats montrent également que d'importants changements socioéconomiques surviennent dans le parc, de nombreux pêcheurs se tournent vers des moyens de subsistance alternatifs, afin de compenser la baisse des prises de poissons. Enfin, cette étude a révélé que d'importants changements positifs dans les préoccupations environnementales sont survenus depuis la modification du zonage du parc, mais que ceux-ci ne se sont pas entièrement traduits en conformité avec les règles et règlements de l'AMP. / This research examined a few important issues related to marine protected area (MPA) management in Indonesia by looking at how MPAs are able to adapt their policies in order to better suit evolving socioeconomic and ecological conditions, what socioeconomic impacts have been felt as a result of MPA implementation, and what are the environmental subjectivities of local actors whose livelihoods are dependent on the resources that are being regulated. The livelihoods framework served as a guide when examining local socioeconomic changes in the region, while Agrawal’s concept of environmentality provided the theoretical underpinnings when examining the formation of environmental subjects in Karimunjawa National Park. This study found that the policy changes brought about in KNP’s reworked management plan are a step in the right direction, but that important goals related to park co-management were never fully realized in practice. The results also show that significant socioeconomic changes are occurring within the park, with many fishermen turning to alternative livelihoods in order to offset declining fish catches. Lastly, this study uncovered that significant positive shifts in environmental subjectivities have occurred since the re-zoning of the park, but that these have not fully translated into compliance towards the rules and regulations of the MPA.

La participation des pêcheurs artisanaux a longtemps été écartée de la gestion institutionnelle des activités halieutiques marines côtières dans la zone intertropicale, notamment au sein des États centralisés d’Amérique Centrale. L’objectif majeur de cette thèse était de déterminer le potentiel de cogestion des activités halieutiques artisanales au sein du Golfo Dulce (Pacifique Sud du Costa Rica). La réflexion s’organise en deux parties. La première est consacrée à l’étude de la gestion des activités halieutiques artisanales exploitant les ressources marines côtières, ressources communes, dans les pays en développement tropicaux, et la seconde, à une étude de cas du Golfo Dulce. Dans un premier temps, le secteur halieutique artisanal costaricain a été caractérisé, notamment au travers de son évolution historique et de sa gestion déconcentrée et pluri-institutionnelle. Les différentes modalités de participation des pêcheurs artisanaux à la gestion de leurs activités halieutiques sont illustrées par plusieurs études de cas (Cahuita, Marino-Ballena, Palito, Tárcoles, Golfo Dulce). Dans un second temps, les pratiques de pêche et le profil socio-économique des pêcheurs artisanaux des trois communautés de Bahía Pavones (sud-est du Golfo Dulce) ont été caractérisés. L’activité de pêche artisanale y repose sur huit espèces, dont les deux principales, Lutjanus gutattus (vivaneau rose) et L. peru (vivaneau garance) seraient surexploitées. La participation des pêcheurs artisanaux aux organisations locales est importante malgré un déficit de confiance envers ces dernières. Enfin, la comparaison des différentes études de cas a mis en évidence l’existence de huit conditions nécessaires au développement d’un processus de cogestion d’activités halieutiques artisanales au Costa Rica. Au sein de l’Aire Marine de Pêche Responsable du Golfo Dulce, malgré la volonté des pêcheurs artisanaux de participer à une pêche durable, c’est la manipulation de ces derniers par divers acteurs qui entrave le processus de cogestion. / The participation of small scale fishers in institutional management of tropical coastal marine fisheries activities has long been excluded, notably in the centralized states of Central America. The major objective of this study was to determine the potential of co-management of coastal marine small scale fisheries activities in Golfo Dulce (South Pacific of Costa Rica). The study consists of two main parts. The first analyses the management of small scale fishing activities exploiting coastal marine resources in tropical developing countries, and the second is devoted to the case study of Golfo Dulce. In a first step, the Costa Rican small scale fishery sector was characterized, especially its historical evolution and its decentralized and multi-agency management. The various modalities of the participation of small scale fishers in its management were illustrated by several case studies (Cahuita, Marino-Ballena, Palito, Tárcoles, Golfo Dulce). Second, fishing practices and socio-economic profile of small scale fishers of the three communities of Bahía Pavones (southeast of Golfo Dulce) were characterized. The small scale fishing activity is essentially based on eight species, of which the two main ones, Lutjanus gutattus (spotted rose snapper) and L. peru (Pacific red snapper) could be overexploited. The participation of small scale fishers to local organizations is significant despite a general lack of confidence towards these organizations. Finally, comparing the different case studies revealed the existence of eight key conditions for the development of a successful co-managed small scale fishery in Costa Rica. Within the Marine Responsible Fishing Area of the Golfo Dulce, it is the manipulation of small scale fishers by various user groups (in particular government and the tourism sector) that hinders the process of co-management.

Tourism fuels the Zanzibari economy but adds to the depletion of marine resources. However, the concept of corporate biosphere stewardship suggests that companies with consolidated power can influence sustainability pathways. Can tourist hotels practically support octopus closures, a novel conservation tool, as a way towards sustainable marine resource consumption? I address this issue by making the first known attempt to estimate Zanzibari hotels’ seasonal and annual octopus demand, mapping their value chain structure and identifying the nature of their demand. The study relies on semi-structured interviews of 31 respondents (hotel staff, hotel suppliers, market traders, food importers and key informants) and official data. I assess the demand of hotels to range between 16 to 27 percent of the mean 2008-2018 annual catch in Zanzibar. Hence, this consumer power hotels may confer agency for them to contribute to resource conservation such as octopus closures. Hotels may support closures particularly if they match seasonality in octopus price and demand. However, hoteliers’ use of a wide sourcing network including imports may lead to diluted price signals hampering understanding and incentives to protect the local octopus supply. Additionally, hoteliers’ weight preferences largely correspond with the Zanzibari voluntary minimum weight limit, but do not align with the desired outcome of bigger octopus from closures. The typical practise of purchasing fresh octopus and limited freezer capacity of hotels may also limit their agency to support octopus closures. This study makes a novel contribution of linking octopus conservation with tourism. It furthermore nuances the concept of corporate biosphere stewardship by assessing the practical potential of Zanzibari tourism, a less consolidated industry, to contribute to marine resource conservation.  Further research into local biosphere stewardship of value chains within low-income country contexts should investigate differences in use of consumer power by small as opposed to large-scale businesses. In addition, similar assessments could benefit from research into local spatial and relational value chains, and their influence on hoteliers’ capacity to perceive of supply status through price signals, not only for octopus but seafood in general. / Utalii unakuza uchumi wa zanzibar lakini umekubwa na kupungua kwa rasilimali za bahari. Ingawaje, dhana ya uhirika wa kibailogio stewardship umependekeza kua nguvu ya mashirikiano ya makampuni yanaweza kuchangia njia endelevu. Inawezekana kwa mahoteli ya kitalii yakatoa msaada wa vitendo wa kufungia pweza wasivuliwe kwa kipindi maalumu, kama zana ya uhifadhi wa mazingira ambayo ni njia ya kupelekea matumizi endelevu ya matumizi ya rasilimali ya bahari? Ninaangalia suala hili kwa kufanya majaribio ya kwanza kwa kukadiria mahitaji ya pweza kwa hoteli za Zanzibar kwa msimu na kwa kila mwaka, kuyaainisha maeneo ya mnyororo wa thamani na kutambua maumbile ya upungufu wake. Utafiti huu ulikuwa ni wa muundo wa mahojiano ya wazi na watu 31 walihojiwa (wafanyakazi wa hoteli, wasambazaji wa mahoteli, wauzaji wa masokoni, wasafirihaji na watu wengine wanohusika) na taarifa za takwimu. Nilipima mahitaji ya mahoteli kwa asilimia kati ya 16 mpaka 27 ya jumla 2008-2018 upatikanaji wa kila mwaka kwa zanzibar. Hivyo basi nguvu ya maoteli wanaweza kua mashirika ya kuchangia uhifadhi wa rasilimali kama kufungia mwamba kwa uvuvi wa pweza. Mahoteli yanaweza kuwasaidia kufungwa kwa mwamba kwa uvuvi wa pweza hasahasa ikiwa watafanana kwa msimu na kwa upatikanaji. Ingawaje wenye mahoteli wanatafuta chanzo kikubwa ikiwemo kuagiza kutoka nje ambayo inaweza kushusha bei na ni ishara ya kuzuia kutoa motisha ya kulinda usambazaji wa ndani. Kwakuengezea wenye mahoteli uzito wanaoupendelea unawiana na ule wa kiwango cha chini cha Zanzibar, lakini hayaendani na matokeo ya matakwa yao ya pweza wakubwa wakati wa kufungia mwamba kwa uvuvi wa pweza. Mahoteli hayawezi kuwa kama mashirika ya kusaidia kufungs pweza kutokana na kutaka pweza ambao wametoka kuvuliwa na vilevile uwezo mdogo wa majokofu yao kuweza kuhifadhi pweza hao. Utafiti huu utaleta mchango mpya baina ya uhifandhi wa pweza na utalii. Na vilevile itaelezea dhana ya mashirikiano ya kibiosphere stewardship kwa kuchunguza umuhimu halisi wa utalii wa Zanzibar, muunganiko mdogo wa wadau katika kuchangia uhifadhi wa rasilimali za bahari. Tafiti zijazo zinazohusiana na biosphere stewardship ya mtiririko wa thamani kwa muktadha wa nchi zenye kipato kidogo zifanye uchunguzi juu ya tofauti ya nguvu ya watumiaji wadogo wadogo inavyoenda kinyume na biashara kubwa. Kwa kuengezea uchunguzi kama huo utanufaisha watu wa hali za chini na mahusiano ya mnyororo wa thamani na mchango wao kwa uwezo wa wenye mahoteli kutambua hali ya usambazaji kupitia bei zake si kwa pweza peke tu bali ni kwa vyakula vya baharini vyote.

The study explored, described and explained the current models of voluntary counselling and testing services delivery and analysed the extent to which a given VCT model had influenced uptake of VCT services in the fishing communities along the shores of Lake Victoria, in Wakiso District, with an aim of designing optimal VCT service delivery strategies. The study was therefore exploratory, descriptive and explanatory, and collected both qualitative and quantitative data in a three-phased approach. Phase I involved the Kasenyi fishing community respondents, while phases II and III involved VCT managers and VCT counsellors at the Entebbe and Kisubi Hospitals. The findings indicated that VCT services are generally available onsite at health facilities, and in the field through mobile VCT outreach or home-based VCT services provided at clients’ homes. Both client-initiated and health provider-initiated VCT services are available and services are integrated with other health services. Despite the availability of VCT, only about half of the respondents in phase I had accessed VCT services although almost all indicated a willingness to undergo HIV testing in the near future. The main challenges to service delivery and utilisation included limited funding and staffing as well as limited awareness in target communities. The strategies drawn are based on the need to increase availability, accessibility, acceptability and utilisation of VCT services. / Health Studies / D. Litt. et Phil. (Health Studies)
