Completed as a series of manuscripts, this dissertation reflects four aspects of my research into the intersections of conservation and sustainable development as practiced by conservation land trusts and community landcare groups, as well as by faculty and staff at land grant universities. The first paper included in this dissertation explores "Conservation 2.0" strategies being developed and employed by land trust across the US to integrate social and economic development goals into their conservation missions. The second paper explores one of these Conservation 2.0 strategies in greater detail, in particular the support of ecological entrepreneurship by land trusts and partners they involve in "ecological entrepreneurship support networks". The third piece emerged out of five years of engaged research with Catawba Landcare as one community landcare group in the region. As a means to capture the development path and history of the organization as well as to facilitate its path forward, I developed a dynamic content management system (CMS) based website for the group, which is explained in Chapter 4. The fourth and final piece of this dissertation is a collaboratively written piece that examines the relationship between Catawba Landcare and Virginia Tech using four theoretical lenses for community capacity building, ultimately proposing one engagement strategy for land grant universities to build and strengthen social infrastructure in their neighboring communities. In total, this collection of works chronicles a larger endeavor to explore place-based sustainability and the role of institutions and civil society in constructing a more sustainable future. / Ph.

Student Number : 9713352V - PhD thesis - School of Animal, Plant and Environmental Studies - Faculty of Science / Over 75 nurseries have been implemented by South African state and non-governmental organisations (NGOs) in conjunction with local stakeholders over the past two decades in attempts to achieve a range of natural resource management (NRM) and social responsibility objectives. Despite occasional successes, numerous projects have failed or struggled to achieve their objectives for prolonged periods. This study aims to identify critical factors influencing the viability of outreach nurseries in South Africa through an evaluation of existing and past projects, and to assess the impact of the projects on the lives of community participants. The central questions of the study are: (i) What factors influence the survival of outreach nurseries? (ii) How did these projects affect the different stakeholders, in particular, community participants? (iii) Are outreach nurseries the best means of achieving conservation and socioeconomic goals? (iv) If so, how can project implementation be improved? Outreach nurseries are defined as decentralised nurseries that are established and managed by one or more community participants with varying degrees of support from implementing organisations. The nurseries included in this study are limited to those with NRM objectives. The key issues affecting the development of outreach projects are reviewed, starting with a brief overview of the evolution of people-centred approaches to NRM. Disentangling the complex inter-related political, socioeconomic and environmental factors influencing the development of even small-scale projects such as outreach nurseries is challenging at both research and implementation levels. A model adapted from Choucri (1999) is presented to facilitate the assessment of projects and the assumptions on which they are based by deconstructing the key dimensions of sustainability: ecology, economic activity, political behaviour, governance and institutional performance. An evaluation of 65 South African outreach nurseries was initially conducted. Biophysical problems such as a lack of water, inadequate infrastructure, poor soils, insufficient space and steep slopes were commonly experienced. Unlike small-scale nurseries in India and other parts of Africa, which are often implemented to meet subsistence needs, South African projects frequently include financial objectives to enable the enterprise to become independent of external funding and generate incomes for community participants. Protracted business difficulties were experienced by 68% of the nurseries. Apart from struggling to develop steady markets, nurseries were often located far from markets and were hampered by inadequate transport, pricing difficulties and limited marketing communications. They were also situated in low-income areas where residents have limited spending power. Few thorough viability studies had been carried out and business management skills were restricted, both amongst community participants and practitioners. Ten outreach nurseries with differing profiles and conservation objectives were then assessed in depth. The achievement of financial and NRM objectives was largely sector dependent. These objectives were usually compatible in greening and conservation rehabilitation programmes, facilitating their attainment. Six nurseries aimed to implement greening activities either through their own efforts at local level or by supplying trees to implementing organisations responsible for regional or national greening programmes. Local level greening initiatives included the planting of trees and ornamentals into school grounds and/or and the surrounding community, the establishment and maintenance of a park, the conservation of remnant patches of indigenous vegetation and encouraging local residents to plant indigenous species. At national level, urban municipalities involved in greening initiatives report an 80% survival rates of transplanted seedlings but high mortalities are frequently experienced in rural areas, mainly due to lack of aftercare and seedlings being eaten by livestock. However, the rate of transplanting of distributed seedlings is frequently unknown. A monitoring plan needs to be designed and implemented in conjunction with recipient organisations, to ascertain whether resources are being effectively used and identify shortcomings. Two nurseries supplied seedlings to gold mining rehabilitation programmes. In total, 580 000 seedlings were transplanted onto 437 ha. of gold mining tailings dams and polluted land between 2002 and 2004. One nursery sold just under 35 000 seedlings to this sector in 2005/6. Initial restoration results have been encouraging, with vegetation on some gold tailings dams establishing so well that a new challenge has arisen: viz. encouraging the neighbouring community to harvest at sustainable levels. A nursery established to supply seedlings to alien plant and wetland rehabilitation programmes closed, but this sector has a similar potential to the gold mining rehabilitation programmes to contribute to biodiversity conservation and enhance ecosystem services whilst contributing to local livelihoods. Both require high volumes of inexpensive, fast growing and resilient seedlings. An endangered species nursery had not yet achieved anticipated conservation returns eight years after its inception, mainly due to an extremely difficult sociopolitical local terrain. Incidents of illegal harvesting of a wild population growing near the project site had declined, but conservation officials were concerned that a general increase in the illegal wildlife trade in South Africa would further pressurize this and other species, for example, those valued for their medicinal properties. Medicinal plant nurseries struggled to simultaneously achieve conservation and socioeconomic objectives. Despite concerted efforts for 6-10 years, none achieved their primary goal at even the scale of the participating group viz. to reduce harvesting levels of wild plant populations. Community participants from two nurseries cultivated medicinal plants at the project site and in their home gardens. Approximately 235 medicinal species were cultivated by 31 participants from one nursery (6-64 species per garden; mean+SE=36.5+2.9), but most people continued to use the same volumes of wild collected material as they had prior to the start of the project. However, six years after the last consistent inputs to the project, several influential traditional healers reported that they still cultivated sufficient volumes to meet their needs, no longer harvested from the wild and seldom purchased plant products from markets. Although this is a promising start, efforts need to be considerably scaled up if regional harvesting levels are to be substantially reduced. Harvesting levels in the other project increased due to beneficiating activities, although practitioners urged the group to harvest leaves rather than bark. A third nursery attained financial viability by marketing its products to the horticultural sector. Traditional healers could not afford the prices asked for plants. The impacts of outreach nurseries on community participants depended largely on whether objectives were achieved, whether costs disproportionately outweighed benefits and the nature of relations between participants and staff from implementing organisations. Although non-monetary benefits were important, almost all community participants aspired to earn financial benefits. However, it took 5-10 years for three nurseries to start generating regular financial returns and only two had generated enough to pay participants consistently. Only 9% of the participants who had been involved in projects from the start derived an income. Costs such as time, money and labour substantially outweighed material benefits. Despite high drop out rates, many people persisted as they strongly wanted the project to succeed and feared forfeiting the effort and resources that they had already invested. Participants from projects that had attained their goals gained self confidence, personal satisfaction and respect within the community. Increased knowledge was highly valued, as was local access to seedlings and, in some projects, enhanced food security. However, many participants felt that they had derived no benefits. Material, social and emotional costs were high, particularly where promised funding and support had not materialised. A rapid-results approach was suggested to boost benefits within a reasonable time frame. There was a distinct differentiation in the nature of social relations between community participants and implementing organisations from different sectors. The forestry sector succeeded in balancing task, group maintenance (sound working relationships) and individual needs in most projects, with community participants actively managing or participating in all but one. A regional conservation agency experienced difficulties in achieving individual and group maintenance needs, but had accomplished task needs. Steps had been taken to address the former. Community participants were actively involved in decision making at the time of the interviews. The national conservation agency had not provided support to outreach nurseries in two different provinces, despite being the primary supporting agency in one instance. A practitioner from an NGO displayed group maintenance attributes such as caring and consideration towards community participants, but neither task nor individual needs were met. Problems here appeared to be due to a lack of development experience. Prolonged restructuring of state organisations negatively affected some projects through high staff turnovers, fluctuating policy environments, and low morale and job uncertainty of staff. The operational styles of individuals and supporting organisations strongly influenced the process, as did the socioeconomic and political environment. Authoritarian personalities or organisations exacerbated conflicts while those that operated in a spirit of cooperation managed to resolve differences. Common causes of conflicts between community participants included scarce resources, perceived distributive injustices, jealousies and lack of, or confusion over, accountability. Conflicts spiraled into violence in two projects, and practitioners were threatened with violence in two. Fostering cooperative relationships and operational environments requires a substantial effort from the outset. Ongoing education for both staff and community participants in effectively managing conflict is vital to improve the productivity and longevity of projects, and can sometimes contribute to improved relations in the wider community. This study has highlighted the constraints of outreach nurseries in contributing to the well-being of local stakeholders, particularly when basic development and business fundamentals are not adhered to. Alternate NRM and income generating strategies need to be evaluated during planning as a nursery may not be the best means of achieving either of these. Although small scale and relatively straightforward compared with many ICDPs, outreach nurseries usually require substantial support, including a range of technical, business, and development services. Implementing organisations need to realistically evaluate potential costs and risks to community participants at the outset and determine whether they have the resources and commitment to provide the levels of support that are likely to be required in a project of this nature. Short-term benefits need to be incorporated into planning, and costs mitigated where possible. Project time frames need to be reconsidered, as practitioners estimate that it takes 5–10 years for nurseries to start meeting objectives, and donors and implementing agencies frequently operate on 2–3-year project cycles. Progress needs to be continuously monitored to enable institutions and community participants to adapt to changing conditions and ensure that the spectrum of objectives are being achieved. Cooperative working environments need to be actively fostered and conflict management skills developed, particularly in difficult sociopolitical terrains.

Med syftet att undersöka hur ett föremåls autenticitet påverkas av renovering/restaurering, har tolkningar av tre författares respektive syn på begreppet autenticitet applicerats på två restaurerade armbandsur. Renoverings- och restaureringsmetoden som har granskats är lasersvetsning, vilken är snabbt växande till följd av sina positiva egenskaper. Då armbandsurens ekonomiska värde stiger i takt med att det allmänna intresset blir större, finns relevans i att studera den renoverings- eller restaureringsmetod oftast diskuteras i samband med ekonomiskt värde. Även om författarnas ståndpunkter skiljer sig åt, så tycks en gemensam synpunkt vara att begreppet autenticitet är högst subjektivt. I förlängningen har det lett till slutsatsen att begreppet autenticitet ofta är individuellt och att det möjligtvis bör undvikas vid diskussion av konservering, restaurering och renovering. / With the aim to investigate how an object's authenticity is affected by the renovation/restoration, the interpretations of three authors respective views on the concept of authenticity is applied to two restored wristwatches. The renovation or restoration method that has been examined is laser welding, which is rapidly growing as a result of its positive qualities. Since wristwatches economic value rises in line with the public interest becomes greater, the study of the renovation or restoration method that is usually discussed in the context of economic value is relevant. Although the authors positions may differ, there seems to be a common denominator to the concept of authenticity as highly subjective. This has led to the conclusion that the concept of authenticity is often too individual and that it possibly should be avoided when discussing issues of preservation, restoration and renovation.

Les politiques de conservation de la nature ont largement évolué ces quarante dernières années. Si les premières aires protégées ont été créées selon un modèle ségrégatif, elles s’inscrivent aujourd’hui dans des modèles intégratifs. De fait, les aires protégées et leurs gestionnaires ne jouent plus les mêmes rôles au sein des socioécosystèmes. Leurs objectifs, leurs pratiques de conservation, les modes de régulation et de prise de décision, l’articulation avec les territoires environnants ont évolué. Nous nous concentrons ici sur les réserves naturelles françaises (RN), l’un des principaux outils réglementaires de protection de la nature en France. Nous caractérisons les interactions entre RN et territoires et les enjeux qui y sont liés, dans la perspective de cette transition ségrégatif – intégratif. Cette étude porte sur deux échelles distinctes : l’échelle nationale et l’ensemble des 277 RN, et l’échelle locale avec 10 études de cas. À l’échelle nationale, l’analyse de l’émergence des thématiques liées au développement durable des territoires dans le réseau des RN met en évidence les enjeux institutionnels, organisationnels, culturels et stratégiques de ce réseau, et permet de discuter la thèse d’une institutionnalisation inachevée. Nous montrons ensuite qu’il existe différents types de RN selon les pratiques mises en œuvre par les gestionnaires. Nous analysons ces investissements variés sur la base de trois types de facteurs : (i) les caractéristiques géographiques des RN ; (ii) le gestionnaire : son système de valeur et son profil socioculturel et (iii) les caractéristiques du territoire environnant. Avec nos 10 cas d’étude, nous caractérisons les socioécosystèmes constitués par les RN et les territoires environnants. Nous analysons dans le détail l’articulation identifiée à l’échelle nationale entre perceptions des acteurs, pratiques, caractéristiques des sites, des territoires et des gestionnaires, à l’intérieur des RN, mais également au-delà de leurs limites spatiales et fonctionnelles. À l’aide des cadres d’analyse des socioécosystèmes complexes, de la solidarité écologique, de la political ecology et de l’analyse institutionnelle, nous identifions les interactions entre RN et territoire, et mettons en lumière les limites des arrangements institutionnels mis en œuvre. Nous concluons sur la notion de trajectoire des sites, et dans une perspective de recherche appliquée, sur les implications de nos résultats pour le réseau des RN. / During the last four decades, nature conservation in protected areas (PAs) has been characterized by major changes. Early PAs have often been perceived as human-exclusion areas, whereas modern PAs have been designated more as integrated conservation and development projects. This evolution has involved major changes in objectives, management practices, governance systems, and relationship of PA’s to their surrounding environments. Nowadays, PA managers take into account processes that go beyond PA boundaries, investigate economic and social issues of development, and pay a special attention to local involvement. Here, we focus on French Nature Reserves (NRs), one of the main regulatory tools of the French nature protection policy. We characterize the interactions between NRs and the socioecosystems in which they interact. This study focus on two scales: the national scale and all of the 277 nature reserves, and the local scale with 10 case studies. At the national scale, we show how the emergence of sustainable development discourses in the nature reserve network have led us to analyze institutional, organizational, cultural and political issues. We describe the distribution of NR practices along a gradient going from a traditional model to an integrative model. We explain the observed practices as a combination of three types of variables : (i) general geographical characteristics of the NRs; (ii) value systems and perceptions of managers and (iii) characteristics of surrounding environments. On the basis of 10 case studies, we characterize the socioecosystems constituted by NRs and their surroundings territories. We analyze the articulation identified at the national scale between conservation practices, characteristics of NRs, territories and managers, both inside the reserves and beyond their spatial and functional boundaries. On the basis of frameworks for analyzing sustainability of complex socioecosystems, ecological solidarity, political ecology and institutional approaches, we identify the key variables in the implementation of collective action and adaptive management of both NRs and socioecosystems. Our analysis illustrates the limits of the implemented institutional arrangements. We conclude on the idea of NR trajectories, and on the practical implications of this work for the French NR system.

This research examines the influence of tourism on migrants’ decisions to move to La Fortuna, Costa Rica, located in the buffer zone of Arenal National Park. Tourism is integral to Costa Rica’s economy and is closely connected to its national parks. Ecotourism is proposed as a non-extractive way for local people to benefit from natural resources, thus contributing to economic development and supporting conservation initiatives. However, if employment opportunities related to tourism encourage high rates of migration to edges of parks, then the resulting population growth could be detrimental to biodiversity conservation goals. Forty participants were interviewed for this project, which used cultural consensus analysis and semi-structured interviews to examine participants’ own behavior as well as shared cultural knowledge of factors that influence migration decisions. Results show that while employment opportunity was influential, other factors such as social stability and tranquility were equally important in participants’ motivations for relocating.

Les stratégies de conservation de la nature évoluent de la protection stricte d'espaces isolés et dépourvus d'activités humaines, à l'intégration des enjeux de biodiversité dans le développement territorial. Ce changement de perspective, des aires protégées à la territorialisation de l'environnement, suppose de gérer la complexité et d'appréhender la nature collectivement et met l'accent sur les relations entre science, politique et société. Cette thèse, fondée sur une approche pluridisciplinaire, a eu pour objectif l'élaboration de recommandations pour répondre aux enjeux d'une conservation intégrée de la biodiversité. S'inscrivant dans le contexte de l'avènement des stratégies de réseau écologique en France, notre recherche porte à la fois sur les méthodes spatiales et sur les dispositifs socio-techniques en charge de planifier la conservation intégrée de la biodiversité. Chacune de ces parties a mené à des résultats et conclusions qui leur sont propres et a contribué à une réflexion plus globale sur le rôle de l'expertise technique pour répondre à ces nouveaux enjeux. Nous montrons comment une approche trop technique, centrée notamment sur la spatialisation du réseau écologique, tend non seulement à limiter le partage au sein du collectif et donc l'adhésion des acteurs mais aussi à fournir une vision réductrice et partielle des enjeux de conservation. A l'inverse, un positionnement de l'expertise en accompagnement du dialogue territorial favorise l'apprentissage social et aboutit à un cadre d'action publique qui intègre davantage les incertitudes et la complexité du vivant. Le processus participatif doit donc permettre d'opérer un glissement de l'expertise technique comme fondement de l'action publique à l'expertise collective qui assure l'intégration des savoirs et savoirs-faire de tous. Ainsi l'enjeu n'est pas celui du compromis entre science, technique et débat social mais plutôt celui de la gestion de leur interaction et de leur complémentarité. / Nature conservation strategies evolve from the strict protection of isolated and devoid of human activity spaces, to the integration of biodiversity issues in territory development. This change in perspective requires the development of a collective management of complexity and a collective conception of nature and highlights the developing relationship between science, policy and society.Based on a multidisciplinary approach, the objective of this thesis was the elaboration of recommendations for integrated conservation. In the context of the advent of ecological network strategies in France, our research concerns both the spatial methods and the socio-technical process which are in charge of the conservation planning. The analysis of these two issues has produced results pertinent to each theme and more general reflection concerning the role of technical expertise in the development of such new issues. We show how an overly technical approach, which notably aims to spatially identify the network, tends to limit the collective sharing of major issues and thus the adherence of the stakeholders to conservation goals, and also provide a reductive and partial vision of conservation issues. In contrast, a position of expertise which accompanies the dialogue on territory favors social learning and leads to a framework for public action which more fully integrates both the uncertainty and complexity of the natural world. The participative process could thus allow tfor a transition from technical to collective expertise as the foundation of public action, which ensures the inclusion of general knowledge and know-how. In this way, the issue is not of a compromise between science, technique and social debate, but of the way that they can complement each other through interaction and how this interaction may be conducted.

The EU Directive for building energy performance requires all member states to reduce energy consumption and CO2 emissions in the existing building stock. A key instrument in achieving this is using building stock modelling as a tool for planning and development of policies. But since the building stock as a whole is a complex element to study, new interdisciplinary methods are required to facilitate a sustainable management of the built heritage. Moreover, as the goal of energy conservation is brought into a supposed conflict with the built heritage, the field of integrated conservation has a responsibility to be a part of the development of such methods. This thesis accordingly investigates state-of-the-art building stock models from several disciplines with the aim of developing a new method for categorising historic building stocks. The historic buildings in the case study of World Heritage Site Visby, Sweden, were surveyed and triangulated using e.g. on-site inspections, digital cadastre maps, the national EPC database and existing inventories, ultimately leading to 1048 buildings from before 1945 being included in a new inventory. This inventory, along with tools acquired from previous buildings stock models, enabled an iterative process to develop and validate the new categorisation method. The proposed method itself is based on the principal idea of categorisation where the building stock is represented by a limited number of categories which allow for further typology investigations, e.g. energy modelling, and extrapolation back to district level. The results show that the building stock can be represented by nine physical categories covering 86 % of the total number of buildings, and 70 % of the entire building volume. To encompass aspects regarding cultural heritage significance, the respective historic character of the buildings are assessed and described by combining statistical information and the Conservation plan of Visby. In all, the method shows to provide a supportive platform for investigations of a trade-off between energy conservation on one hand and building conservation on the other. / EFFESUS / Spara och Bevara

Denna studie söker sammanfatta och analysera ett drygt sekels samlingsförvaltning och autenticitetsbruk av sekelskifteskonstnären Julius Kronbergs ateljé, som sedan 1922 funnits som museal miljö på friluftsmuseet Skansen i Stockholm. Problemet som utgör studiens fokus kretsar kring den bevarandeproblematik som uppstått då man i samma stund velat använda och bevara en autentisk miljö som i grund och botten har tämligen dåliga bevarandeförutsättningar. Studien har genomförts utifrån arkiv- och litteraturstudier samt en intervju, och inleds med en bakgrundshistorik följt av ett resultat som är uppdelat i fem delkapitel som alla motsvarar varsin tidsepok i förvaltningen av ateljén. De slutsatser som kan dras av resultatet visar på hur förvaltningen delvis har skiftat under seklet, att bevarandeproblematiken ofta har lösts genom att nedprioritera tillgängliggörandet av miljön, samt att miljöns materiella autenticitet genomgående har varit väldigt viktig. / This study aims to recap and analyze a century of collections management and authenticity use of artist Julius Kronbergs studio, that has been a part of Skansen open air museum in Stockholm since 1922. The problem for the study revolves around the desire to use and preserve an authentic environment that shows poor prerequisites in terms of preservation. The study has been carried out based on archive and litterature studies aswell as an interview, and is commenced with a historic context, followed by the result that is divided into five chapters based on different eras in the collections management of the studio. The conclusions shows how the management has varied some during the century, that the problem in preservation often was solved by down prioritizing the use of the museum environment, and that the studios material authenticity was very important throughout the century.

Undersökningens syfte var att belysa vilken typ av information som utställningen ”Mittens rike” på Östasiatiska museet gav och därav visa ett exempel på hur det kinesiska kulturarvet kan tolkas av att befinna sig i en svensk kontext. Genom att belysa de delarna kunde diskussionen angående asiatisk och europeisk kulturvård och kulturarv belysas där deras olika ståndpunkter kring autenticitet och rituella praktiker kunde framhävas. Som undersökningsmetod användes en utställningsobservation som kompletterades med andra personliga kommunikationer och litteratur. Resultatet visade att utställningen delade information om kinesiska föremål från deras bronstid fram till början av 1900-talet som antingen kopplades till en viss dynasti, till olika föremålsutvecklingar med hantverksmetoder eller till olika samhällsfenomen som föremålen representerade. Utställningstexter och föremålsbeskrivningar bidrog med kontextbyggandet av föremålen, men det fanns även några montrar utan utställningstext där besökaren kunde skapa en egen uppfattning av föremålen. Den europeiska och svenska inblandningen visades främst i utställningens exportporslin som fanns över en stor del av utställningens senare halva. Handeln mellan Kina och Europa/Sverige blev därav det centrerade perspektivet i både föremålen och i utställningstexterna vilket skapade en stor kontrast till tidigare del som enbart fokuserat på de kinesiska utvecklingarna. Det resulterade i att det kinesiska kulturarvet hamnade i skuggan av främst den svenska inblandningen, och blev då en biroll i montrarna som framhävde de svenska framgångarna. / The purpose of the study was to enlighten the type of information the exhibition “The middle kingdom” at the Museum of Far Eastern Antiquities gave and therefore show how the Chinese cultural heritage can be interpretated by existing in a Swedish context. By showing those parts, the discussion of Asian and European integrated conservation and cultural heritage be uplifted and show the different point of views according to authenticity and ritual usage of objects. An exhibition observation was used as the main method with complementary information from personal correspondence and literature. The result showed the exhibition shared information about Chinese objects from their bronze age to the beginning of the 20th century, all connected to a certain dynasty, to different evolutions of objects with certain craft methods, or other societal evolutions which was represented by certain objects. The exhibition text and the object descriptions contributed to the contextualization of the objects, but also showed showcases without any text, which allowed the visitor to create their own perception about the objects. The European and Swedish involvement was displayed especially in the exhibitions exported porcelain that appeared in a big part of the latter half. The trade between China and Europe/Sweden therefore became the central perspective in both the objects and texts in the exhibition which created a big contrast between the earlier part who only focused on the Chinese evolutions. It resulted in the Chinese cultural heritage placed in the shadows of mainly the Swedish involvement and became a subordinate part in the showcases and highlighted the Swedish success stories.

Depuis les années 90, les Projets Intégrés de Conservation et Développement ont été présentés comme des modèles fonctionnels de développement durable pour un site spécifique dans une perspective de réalisation. Le but est d’intégrer les objectifs biologiques de la conservation aux objectifs sociaux et économiques du développement. Ces projets, qui répondent à de multiples dénominations et stratégies, sont implantés dans des contextes naturellement hétérogènes et dynamiques, où l’aménagement du territoire ne doit pas être un outil de planification étatique, désigné et imposé dans une logique conservationniste. Les aires protégées représentent une certaine vision du rapport entre l’être humain et la nature, apparue dans le contexte nord-américain avec la création des premiers grands parcs nationaux en 1870. Aujourd'hui, la forte volonté d'impliquer la population se heurte avec la difficulté de concilier la gestion de ces espaces avec les pratiques, les nécessités et les intérêts locaux. Le parc naturel Obô, qui occupe 30% du territoire de São Tomé et Principe, doit affronter la difficile intégration entre les représentations de la nature et les usages locaux avec les objectifs globaux des politiques conservationnistes, ainsi qu’avec les intérêts touristiques et économiques des investisseurs locaux et étrangers. Les représentations sociales de la nature, établissant une forme de connaissance pratique, déterminent la vision du monde et la relation qu'un certain groupe social peut avoir avec le territoire. Ainsi, chaque communauté possède ses propres mécanismes d'adaptation au milieu basés sur ce système représentationnel. Dans le cas des communautés sãotoméennes, la nature présente un caractère spirituel (associé à des croyances, des rites et des pratiques médicales traditionnelles) et utilitaire (la nature, à travers l'agriculture, la récolte ou la chasse, répond au besoin de subsistance). L’objectif de ce projet de thèse est donc de mieux comprendre la synergie existante entre savoir endogène et gestion de la biodiversité pour adapter l’aménagement du territoire à la réalité des populations qui y vivent. / Since the beginning of the 1990s, Integrated Conservation and Development Projects have offered a functional model of sustainable development for specific sites within the perspective of particular projects. Their goal has been to integrate biological aspects of conservation to the social and economic aspects of development. Protected areas represent a particular vision of the relationship between man and nature, appeared in the American context with the creation of the first national parks. Currently, the wish to involve the population in the creation of protected areas faces the challenge of reconciling the management of these spaces with the local practices, needs and interests. Obô Natural Park, which occupies 30% of the territory of Sao Tome and Principe, follows the difficult process of integrating both local uses and representations of nature to the global objectives of conservationist policies while considering the touristic and economic interests of local and foreign investors. Social representations of nature, understood as a form of practical knowledge, determine the vision of the world and the relationship that a particular social group may have with its territory. Thus, based on this system, each community has its own mechanisms of environmental adaptation. In the case of the Saotomean communities, nature presents a strong spiritual (associated with beliefs, rituals and traditional medical practices) and utilitarian character (nature provides, through farming, collecting or hunting, all you need to live). The aim of this thesis is to understand the synergies between endogenous knowledge and management of biodiversity to adapt the land management process to the reality of the people who live in the particular territory of Sao Tome and Principe.
