Esta tese tem como tema o conjunto de recursos comuns naturais e os formatos de gestão que permitem novos sistemas de governança nos espaços rurais no entorno de áreas protegidas. Como questão central, busca responder como os diversos atores afetados pelo processo de criação de uma área protegida organizam-se e desenvolvem ações coletivas para a gestão dos recursos comuns no entorno destas áreas. Têm-se como hipótese que há uma aproximação entre os atores conforme seus objetivos em relação aos recursos comuns naturais, o que remete a configuração de um novo sistema de governança que propicia o desenvolvimento de ações coletivas próprias de gestão dos recursos comuns. Outra hipótese é que a ação do Estado, por meio de políticas governamentais, apresenta efeito limitado na coordenação das ações e na promoção do consenso entre os atores. Desta forma, o objetivo deste trabalho é estudar a ação coletiva dos atores sociais na gestão dos recursos comuns no entorno do Parque Nacional da Serra da Bodoquena (PNSB), o qual abrange áreas dos municípios de Bodoquena, Bonito, Jardim e Porto Murtinho no Estado de Mato Grosso do Sul. Por meio da abordagem institucional no estudo da auto-organização e autogovernança em situações de gestão do conjunto de recursos comuns desenvolvida por Elinor Ostrom, buscou-se a fundamentação teórica para explicação dos fenômenos e problemática identificada. Metodologicamente trata-se de uma pesquisa de campo e documental, a qual apresenta um delineamento de estudo de caso small-N, aplicando-se o framework para análise de sistemas sócio-ecológicos (SES), procedendo-se também uma sistemática análise documental próxima à meta-análise. Conclui-se que a esperada mobilização de grupos de indivíduos em busca de objetivos comuns encontra duas vertentes neste caso, com os participantes da arena de ação criando distintos objetivos e distintas ações coletivas de acordo com seus interesses, produtivos ou ambientais, sendo que governo dos comuns permanece sob o controle dos interesses produtivistas arraigados na cultura de produção agropecuária local. / This thesis has as its theme the common natural resources and the management models that allow new governance systems in the rural areas in the surrounding of protected areas. As central question, seeks to answer how the various actors affected by the process of creation of a protected area organise themselves and develop collective actions for the management of common natural resources in the surroundings of this area. There has been hypothesised that there is a closeness among the actors as their goals in relation to common natural resources, which refers to setting up a new governance system that promotes the development of collective actions specific to the management of common resources. Another hypothesis is that state action, through government policies, has limited effect on the coordination and promotion toward a consensus among actors. In this sense, the objective of this work is to study the collective action of social actors in the management of common natural resources in the surroundings of the National Park of Serra da Bodoquena (PNSB), which covers areas of the municipalities of Bodoquena, Bonito, Jardim and Porto Murtinho in the State of Mato Grosso do Sul. Based on institutional approach for the study of the self-organisation and self-governance in common-pool resources situations developed by Elinor Ostrom, the investigation sought the theoretical explanation of phenomena and problem identified. Methodologically this is a documentary and field research, which has a feature of small-N case of study, proceeding an applying of the framework for analysing social-ecological systems (SES), conducting also a systematic analysis of documents close to a meta-analysis. The conclusions point out that the expected mobilisation of groups of individuals in the pursuit of common goals is twofold in this case, with the participants of the action arena creating different goals and different collective actions according to their interests, environmental or productive, and that the govern of the commons remains under the control of agribusiness interests rooted in the culture of the local agricultural production.

Les récifs coralliens hébergent la plus grande biodiversité sur Terre et fournissent la nourriture, le revenu économique, la protection côtière et les valeurs culturelles pour des millions de personnes. L'accessibilité des écosystèmes via les réseaux routiers est un déterminant majeur de leurs conditions, les écosystèmes les plus accessibles étant les plus menacées. Longtemps, l’estimation de l'accessibilité par l’Homme s’est limitée à l'utilisation de la distance linéaire qui ignore l’irrégularité des côtes maritimes et les réseaux routiers, facteurs influençant le temps nécessaire pour atteindre les lieux de pêche. Cette thèse présente un double enjeu : (i) développer des indices d'accessibilité intégrant l’hétérogénéité du milieu marin pour quantifier les impacts humains sur les récifs ; (ii) évaluer l'importance de ces nouveaux indices, en interaction avec les mesures de protection, pour expliquer les variations de la biomasse de poissons. Dans un premier temps, j’ai caractérisé la proximité des hommes aux récifs, en tenant compte des surfaces rencontrées (routes, chemin, eau) qui influencent le temps de trajet jusqu’aux récifs. Le temps de trajet a permis de calculer un indice de gravité, défini comme la population humaine divisée par le temps de trajet au carré, pour évaluer le niveau de pression humaine de n'importe quel récif au monde. J'ai trouvé que le temps de trajet et la gravité sont des déterminants majeurs de la biomasse de poissons à l’échelle globale. Dans un second temps, trois applications utilisant ces nouveaux indices ont permis de montrer que (i) la gravité permet de révéler l’efficacité des actions de conservation : les réserves placées là où les impacts humains sont modérés à forts fournissent des gains de conservation élevés pour la biomasse de poissons, mais elles sont peu susceptibles de protéger les prédateurs supérieurs, qui sont uniquement présent dans les réserves soumises à de faibles impacts humains ; (ii) en utilisant un cas d'étude réalisé dans le Nord-Ouest de Madagascar, j'ai illustré comment la proximité du marché peut affecter les communautés de pêcheurs et, finalement, engendrer des changements dans l'exploitation des ressources marines ; (iii) j’ai développé une nouvelle approche, le Community-Wide Scan (CWS), pour identifier les espèces de poissons qui contribuent de manière significative à la biomasse et à la couverture corallienne des récifs de l’Indopacifique, celles-ci pouvant constituer des espèces cibles à protéger. Dans le contexte de changements globaux et de perte de biodiversité, la mesure d’accessibilité constitue un outil puissant et permet de relancer le défi de gestion durable et efficace des socio-écosystèmes coralliens. / Coral reefs have the greatest biodiversity of any ecosystem on the planet and support ecosystem goods and services to million people who depend directly on them for food, economic income, coastal protection and cultural values. Ecosystem accessibility, through road networks, is the main driver of their conditions, with the most accessible ecosystems being most at risk of resource depletion. To date, measuring accessibility to humans was strictly limited to examining the linear distance which ignores ragged coastlines and road networks that can affect the time required to reach fishing grounds. This thesis presents a double challenge: (i) developing new metrics of accessibility that account for seascape heterogeneity to better assess human impacts on coral reefs; (ii) evaluating the importance of coral reef accessibility, in interactions with their management, to explain variations of fish biomass. First, I developed novel metrics of reef proximity to human populations and markets based on the friction distance which is related to transport surfaces (paved road, dirt road, water) influencing the effective reach of human settlements. Travel time was used to build the gravity index, defined as human population divided by the squared travel time, to assess the level of human pressure on any reef of the world. I found that both travel time and gravity are strong predictors of fish biomass globally. Second, three applications using these new metrics highlighted that (i) gravity identified critical ecological trade-offs in conservation since reserves placed with moderate-to-high impacts may provide substantial conservation gains for fish biomass while reserve locations with low human impacts were more likely to support higher-order predation, (ii) using a study case in Northwest Madagascar, I illustrated how market proximity can affect fishermen communities and, ultimately, trigger changes in marine resources exploitation, and (iii) I implemented a new Community-Wide Scan (CWS) approach to identify fish species that significantly contribute to the biomass and coral cover on Indo-Pacific reefs and which provided tractable conservation targets. Within the context of global changes and biodiversity loss, the thesis challenges the sustainable and efficient management of coral reef socio-ecological systems with accessibility being the cornerstone.

The present study is one of the first attempts to analyze the societal importance of seagrasses (marine flowering plants) from a Natural Resource Management perspective, using a social-ecological systems (SES) approach. The interdisciplinary study takes place in East Africa (Western Indian Ocean, WIO) and includes in-depth studies in Chwaka Bay, Zanzibar, Tanzania. Natural and social sciences methods were used. The results are presented in six articles, showing that seagrass ecosystems are rich in seagrass species (13) and form an important part of the SES within the tropical seascape of the WIO. Seagrasses provide livelihoods opportunities and basic animal protein, in from of seagrass associated fish e.g. Siganidae and Scaridae. Research, management and education initiatives are, however, nearly non-existent. In Chwaka Bay, the goods and ecosystem services associated with the meadows and also appreciated by locals were fishing and collection grounds as well as substrate for seaweed cultivation. Seagrasses are used as medicines and fertilizers and associated with different beliefs and values. Dema (basket trap) fishery showed clear links to seagrass beds and provided the highest gross income per capita of all economic activities. All showing that the meadows provide social-ecological resilience. Drag-net fishery seems to damage the meadows. Two ecological studies show that artisanal seaweed farming of red algae, mainly done by women and pictured as sustainable in the WIO, has a thinning effect on seagrass beds, reduces associated macrofauna, affects sediments, changes fish catch composition and reduces diversity. Furthermore, it has a negative effect on i.a. women’s health. The two last papers are institutional analyses of the human-seagrass relationship. A broad approach was used to analyze regulative, normative and cultural-cognitive institutions. Cooperation and conflict take place between different institutions, interacting with their slow or fast moving characteristics, and are thus fundamental in directing the system into sustainable/unsustainable paths. Ecological knowledge was heterogeneous and situated. Due to the abundance of resources and high internal control, the SES seems to be entangled in a rigidity trap with the risk of falling into a poverty trap. Regulations were found insufficient to understand SES dynamics. “Well” designed organizational structures for management were found insufficient for “good” institutional performance. The dynamics between individuals embedded in different social and cultural structures showed to be crucial. Bwana Dikos, monitoring officials, placed in villages or landing sites in Zanzibar experienced four dilemmas – kinship, loyalty, poverty and control – which decrease efficiency and affect resilience. Mismatches between institutions themselves, and between institutions and cognitive capacities were identified. Some important practical implications are the need to include seagrass meadows in management and educational plans, addressing a seascape perspective, livelihood diversification, subsistence value, impacts, social-ecological resilience, and a broad institutional approach.

This research focuses on the challenges and opportunities facing local governance agents in advancing an ecosystem approach to conceptualizing and governing community health in Norfolk County, Ontario. Norfolk County is a rural, agriculturally-based community dependent upon tobacco production. This industry has collapsed, triggering widespread socioeconomic impacts and community health pressures. The government is searching for alternative modes of economic development and tensions are high with respect to the direction and nature of these developments. Some citizens are concerned about the security of their rural livelihoods. Others are concerned about ecological integrity. Still others are convinced of the need for aggressive economic growth. Local decision-makers are struggling to meet all of these requirements. An ecosystem approach views health as part of the broader socio-ecological system, recognizing that health outcomes are by-products of complex biophysical, social, political and economic system interactions at nested spatial and temporal scales. The approach contrasts with conventional health models, which tend to be reactionary, narrowly focused, and short-sighted. Such models are typical of the hierarchical, technocratic nature of public administration which renders decision-making structures and processes ill equipped to deal with complex problems. More systemic, integrated, participatory and collaborative approaches to decision-making are needed in order to better address the complexities involved in facilitating healthy and sustainable community development. Additionally, governance agents must also be able to embrace and navigate these evolving approaches to health conceptualization and governance. An investigation into Norfolk County grounds this analysis by revealing the challenges and opportunities facing local governance agents in advancing an ecosystem approach. The case study research effectively tests the utility and feasibility of the ecosystem approach through a qualitative analysis. The research contributes criteria required for advancing an ecosystem approach to community health governance and practice and empirically tests them within the context of Norfolk County.

The objective of the proposed research is to study the integration of humans and automation for the operation of regenerative life support systems (RLSS). RLSS combine physico-chemical and biological processes with the purpose of increasing the autonomy of space habitats and the life quality of their living organisms by properly reusing byproducts and regenerating consumable resources. However, these processes require energy and time to transform chemical compounds and organic wastes into nutrients, consumables, and edible products. Consequently, the maintenance of RLSS imposes a considerable workload on human operators. In addition, the uncertainties introduced by unintended chemical reactions promoted by material loop closure may create unexpected situations that, if unattended, could translate into performance deterioration, human errors, and failures. The availability of novel chemical and biological sensors together with computational resources enable the development of monitoring and automation systems to alleviate human workload, help avoid human error, and increase the overall reliability of these systems. This research aggregates sensor data and human-expert situation assessments to create a representation of their situation knowledge base (\gloss{skb}). The representation is used in a switched control approach to the automation of RLSS, for decision support, and human-automation coordination. The aggregation method consists of an optimization process based on particle swarms. The purpose of this work is to contribute to the methodological development of situation-oriented and user-centered design approaches to human-automation systems. Experiments and simulations are supported on the process of respiration in an aquatic habitat acting as a RLSS.

Syfte Syftet med uppsatsen är att försöka få reda på ny kunskap om vad som kan vara den optimala miljön för en fotbollsspelare på pojksidan. Tanken med studien är också att jämföra hur kulturen i Stockholm och Halmstad ser ut gällande prestige, högsta serie, selektering, specialisering, föräldrar, värdering av att vinna i ung ålder, tränarens roll, faciliteter och vad har föreningarna för möjlighet gällande träningstimmar (bilaga 4). Dessa faktorer kan vara avgörande i varje individs utveckling. Frågeställningar Vad är en optimal miljö för en pojkfotbollsspelare att utvecklas i? Vad är skillnaderna och likheterna mellan miljön i Stockholm och Halmstad? Metod Detta är en kvalitativ studie bestående av intervjuer med en semistrukturell intervjuguide. Tre spelare från Stockholm och tre spelare från Halmstad har intervjuats och de svar som framkommit har analyserats och diskuterats med hjälp av tidigare forskning inom ämnena: faciliteter, familj, tränare, filosofi & kultur, skador, status i skola och nyckeln till framgång. Resultat Resultaten visade på att alla individer är olika, och att det som hjälper en person att slå igenom och ta sig till landslaget kanske inte fungerar för en annan. Flertalet intervjupersoner har lyft familjen som den viktigaste faktorn för att de ska ha lyckats, medan andra har lyft fram deras inre motivation som den avgörande faktorn för deras fotbollsspelande. Gällande plantider så fanns det betydligt fler i Halmstad än i Stockholm sommartid, men under vintern så var det Stockholm som hade flest tider och detta berodde på tillgängligheten till konstgräsplaner. Slutsats I studien så har svaren från intervjupersonerna analyserats och mikrosystemet var den delen som ansågs vara viktigast av stegen ur utvecklingsekologin. Då genom att du måste känna en trygghet i den närmiljö du har. Att hela tiden känna att du kan lita på någon och få feedback från dessa personer. Detta kan både fälla eller stärka en spelare. Vissa spelare passar bättre in med mer regler medan andra passar in med fria tyglar. Här gäller det för spelarna att hitta sin egna väg att gå. De andra nivåerna påverkar givetvis också människan, men i den här studien fann vi mikronivån den viktigaste nivån.

Environ 15 % des terres émergées mondiales sont protégées d’une manière ou d’une autre. Conflits homme/faune, prédation du bétail, pertes agricoles, braconnages divers, la liste des tensions entre aires protégées Africaines et leurs périphéries est longue. Ceux-ci peuvent être vus comme des « problèmes pernicieux », caractérisés par la présence simultanée de valeurs culturelles divergentes et de nombreuses incertitudes sociales ou scientifiques. L’approche constructiviste des sciences « post normales », aborde la réalité comme le résultats d’une construction sociale, et reconnait donc l’existence d’une pluralité de réalités. La participation d’acteurs locaux dans nos démarches scientifiques permet de prendre en compte ces réalités. Cette thèse est focalisée sur les interactions entre la Foret de Sikumi (FS), une aire protégée Zimbabwéenne, et les communautés rurales vivant à sa périphérie. Nous nous sommes intéressés aux tensions liées aux pratiques de conduite du bétail. Nous retrouvons là les caractéristiques des problèmes pernicieux : difficulté à identifier le problème de manière définitive ; incertitudes scientifiques et sociales ; valeurs culturelles conflictuelles et liens avec d’autres problèmes. Pour comprendre et modéliser les interactions entre acteurs à travers la conduite du bétail, nous avons co-construit un outil de recherche participatif sous la forme d’un Jeu de Rôle (JdR) nous permettant d’étudier les stratégies locales de conduite du bétail. Nos travaux montrent comment l’utilisation d’environnements virtuels permettent aux chercheurs de s’extraire du paradoxe majeur des problèmes pernicieux : toute action modifie le système et donc le problème, sans jamais le régler. La participation d’acteurs locaux nous a permis de redessiner une vision commune des incertitudes sociales et scientifiques au travers de processus de négociation. Nous montrons comment le résultat de notre effort collectif dépasse les ambitions premières et la manière dont le chercheur doit nécessairement perdre en partie le contrôle de l’objet construit au profit des partenaires locaux. Finalement, nous exprimons notre conviction que des approches comme la nôtre sont pertinentes pour la gestion des aires protégées, particulièrement avec l’émergence des parcs transfrontaliers en Afrique australe. / About 15 % of the world’s terrestrial area has some kind of protected status. Human-wildlife conflicts, crops raiding, livestock predation, poaching, illegal natural resources harvesting, the list of issues taking place at the edge of African protected areas is long. These issues are wicked problems, characterized by scientific uncertainties and involve conflictive cultural values and interconnections with other problems. The constructivist approach of post-normal sciences (PNS) assumes that reality is socially constructed. Studying and addressing wicked problems therefore requires insights on local stakeholders’ perspectives. In this PhD we focused on interactions between the Sikumi Forest (SF), a Zimbabwean protected area, and the rural communities living at its periphery. More particularly, we focused on the tensions related to cattle herding practices. The situation shows characteristic of wicked problems: the difficulty to frame a precise problem; high uncertainties about the studied SES; incomplete scientific knowledge; competing cultural values; and the interconnection to other problems. In order to understand cattle-related interactions between rural communities and the protected area, we co-designed a participatory research tool taking the form of a role-playing game (RPG) enabling us to elicit cattle herding strategies. The RPG was used with naïve villagers (villagers who were note involved in the co-design). This PhD thesis shows how the use of virtual worlds allows researchers to cope with the catch-22 of wicked problems, that is that any action transforms the problem and brings us “back to the beginning”. The co-design of the research tool allows to deal with one of the major characteristics of wicked problems: uncertainties. In the participatory design of the RGP, these were collectively reframed through negotiation. Participation led to the appropriation of the co-designed object by local actors, as a result our project went beyond the initial ambitions and produced a multi-dimensional tool of which we necessarily lose control. In a wider perspective, we believe that with the emergence of Transfrontier conservation in Africa, participatory approaches like ours can provide alternative ways to study and manage coexistence between protected areas and their peripheries.
