Intégrer les connaissances sur la connectivité écologique dans la gestion des écosystèmes marins est essentiel, surtout dans un contexte d'appauvrissement des ressources marines et de dégradation des habitats côtiers à l'échelle mondiale. Des outils environnementaux, tels que les Aires Marines Protégées ont été mises en œuvre pour protéger la biodiversité, restaurer les écosystèmes endommagés, soutenir les pêcheries et reconstituer les stocks surexploités. Leur efficacité dépend en partie du maintien de la connectivité entre les populations marines, assurée à travers divers processus écologiques dont la dispersion larvaire. Dans le cadre de ce travail de thèse, un modèle biophysique intégrant des données de courants, issues de mesures d'altimétrie par satellite, a été utilisé pour évaluer la connectivité entre les récifs de l'océan Indien d'une part, et à travers le réseau d'AMP de Méditerranée d'autre part. Différentes méthodes d'analyse ont été utilisées, telles que la théorie des graphes et le clustering. Dans l'océan Indien occidental, l'analyse des connectivités marines montre que le nombre de connexions entre les récifs augmente avec la durée de vie larvaire des poissons. Elle met également en évidence une faible connectivité à l'échelle de la région, mais une forte inter-connectivité au sein de plusieurs sous-régions (Canal du Mozambique, Mascareignes). En Méditerranée, la connectance est globalement faible à l'échelle régionale, bien que plus importante dans le bassin occidental que le bassin oriental. L'analyse des connectivités marines montre également un taux de connectivité élevé à l'échelle d'un même pays. Selon le cas d'étude, une liste de récifs ou de sites prioritaires dans la mise en œuvre des AMP a été proposée. Enfin, les implications de ces résultats en termes de politiques transfrontalières et de coopération régionale sont discutées. / Integrating ecological connectivity into marine ecosystem management and planning is important, especially in a global context of severe fish stocks depletion and growing habitat degradation. Environmental tools such as Marine Protected Areas have been proposed to protect biodiversity, restore damaged ecosystems, sustain fisheries, and rebuild overexploited stocks. The effectiveness of marine protected areas depends in part on the maintenance of connectivity between marine populations, linked by ecological processes such as larval dispersal. In this thesis, we applied a biophysical model driven by ocean currents derived from satellite altimetry to evaluate connectivity between Western Indian Ocean reefs and across the current MPA system in the Mediterranean Sea. We applied different methods of analysis such as graph-theoretic and clustering. In the Western Indian Ocean, marine connectivity analyses show that the number of connections between reefs increases with fish pelagic larval duration. It also highlights a low connectivity across the region and a high interconnectivity within several regions (Mozambique Channel, Mascarene archipelago). In the Mediterranean Sea, connectance is globally low at the regional scale. This connectance is more important in Western than Eastern Mediterranean. Moreover, the marine connectivity analyses revealed high domestic connectivity rates. Depending on the study area, priority reefs or sites for MPA implementation are proposed. Finally, implications for transboundary marine policies and regional cooperation are discussed.

In this dissertation, we are interested in the dynamics of spatially distributed populations. In particular, we focus on persistence conditions and minimal traveling periodic wave speeds for stage-structured populations in heterogeneous landscapes. The model includes structured populations of two age groups, juveniles and adults, in patchy landscapes. First, we present a stage-structured population model, where we divide the population into pre-reproductive and reproductive stages. We assume that all parameters of the two age groups are piecewise constant functions in space. We derive explicit formulas for population persistence in a single-patch landscape and in heterogeneous habitats. We find the critical size of a single patch surrounded by a non-lethal matrix habitat. We derive the dispersion relation for the juveniles-adults model in homogeneous and heterogeneous landscapes. We illustrate our results by comparing the structured population model with an appropriately scaled unstructured model. We find that a long pre-reproductive state typically increases habitat requirements for persistence and decreases spatial spread rates, but we also identify scenarios in which a population with intermediate maturation rate spreads fastest. We apply sensitivity and elasticity formulas to the critical size of a single-patch landscape and to the minimal traveling wave speed in a homogeneous landscape. Secondly, we use asymptotic techniques to find an explicit formula for the traveling periodic wave speed and to calculate the spread rates for structured populations in heterogeneous landscapes. We illustrate the power of the homogenization method by comparing the dispersion relation and the resulting minimal wave speeds for the approximation and the exact expression. We find an excellent agreement between the fully heterogeneous speed and the homogenized speed, even though the landscape period is on the same order as the diffusion coefficients and not as small as the formal derivation requires. We also generalize this work to the case of structured populations of n age groups. Lastly, we use a finite difference method to explore the numerical solutions for the juveniles-adults model. We compare numerical solutions to analytic solutions and explore population dynamics in non-linear models, where the numerical solution for the time-dependent problem converges to a steady state. We apply our theory to study various aspects of marine protected areas (MPAs). We develop a model of two age groups, juveniles and adults, in which only adults can be harvested and only outside MPAs, and recruitment is density dependent and local inside MPAs and fishing grounds. We include diffusion coefficients in density matching conditions at interfaces between MPAs and fishing grounds, and examine the effect of fish mobility and bias movement on yield and fish abundance. We find that when the bias towards MPAs is strong or the difference in diffusion coefficients is large enough, the relative density of adults inside versus outside MPAs increases with adult mobility. This observation agrees with findings from empirical studies.

O Parque Estadual da Cantareira é uma Unidade de Conservação de Proteção Integral localizada na Região Metropolitana de São Paulo, abrigando inúmeras nascentes, entre as quais as de importantes rios afluentes do Tietê e outras que contribuem para o reservatório Paiva Castro. Contudo existem poucos estudos sobre a qualidade da água e os ambientes aquáticos desta importante área protegida. Neste contexto, este trabalho objetivou avaliar a qualidade da água de ambientes lóticos do parque, a fim de buscar as condições mais próximas às naturais desta área, partindo do proposto na Resolução CONAMA 357/2005 para a Classe Especial. Para tanto a qualidade da água foi avaliada de forma integrada pela análise do meio físico (topografia e vegetação, utilizando-se imagens de satélite), da avaliação de características fisicoecológicas e do habitat de riachos (pelo emprego de um protocolo de avaliação rápida) e da qualidade da água (avaliação de variáveis físicas, químicas, biológica e hidrobiológica). Os resultados foram analisados de forma integrada e, a partir dos melhores resultados indicados pelas diferentes abordagens, foram selecionados dez riachos que representaram as condições de melhor preservação no âmbito desta pesquisa. Para o período amostrado estas condições são indicadas pelos mínimos valores ou ausência de Clorofila a, Ortofosfato, Ortosilicato, Fósforo Total, Nitrito e Amônio; baixos valores de Nitrato (< 0,81 mg/L), Nitrogênio Total (< 2,1 mg/L), Material em Suspensão Total (< 4,53 mg/L), Turbidez (< 7,1 NTU); valores relativamente baixos de Sólidos Totais (< 92,3 mg/L) e Condutividade Elétrica (< 58 s/cm); Oxigênio Dissolvido acima de 7,6 mg/L e pH entre 6,5 e 7,3. Além disso, deve haver condições fisicoecológicas livres de alterações e hábitats com características de ambientes com ausência ou mínima perturbação. Espera-se que esta pesquisa seja um primeiro passo para o diálogo sobre a viabilidade da busca de condições naturais em unidades de conservação de proteção integral, conhecimento necessário para o reenquadramento destas áreas protegidas na Classe Especial. / The Cantareira State Park is a conservation unit of integral protection located in the Metropolitan Region of São Paulo. It has several springs including those originating relevant tributaries of the Tietê river and others that contribute to Paiva Castro reservoir. However, there are few studies on the water quality and aquatic environments of this relevant protected area. In this context, this research aimed to evaluate the water quality of lotic environments in the park in order to establish the natural conditions of the area, based on the proposed for Special Class by CONAMA Resolution 357/2005. The water quality was evaluated in an integrated manner by performing analyzes of the physical medium (topography and vegetation via satellite images, evaluation of physic-ecological features and habitat of streams (by a rapid bioassessment protocol) and evaluation of the water quality (physical, chemical, biological and hydrobiological analyses). Results were analyzed in an integrated manner and, from the better results indicated by the different approaches, ten sites were selected which represented the best preservation conditions in the Park. For the sampling period, these conditions are minimum values or absence of Chlorophyll a, Orthophosphate, Orthosilicate, Total Phosphorus, Nitrite and Ammonium; low values of Nitrate (< 0.81 mg/L), Total Nitrogen (< 2.1 mg/L), Total Suspended Solids (< 4.53 mg/L), Turbidity (< 7.1 NTU); relatively low values of Total Solids (< 92.3mg/L) and Electric Conductivity (< 58 s/cm); Dissolved Oxygen higher than 7.6 mg/L and pH between 6.5 and 7.3. Besides it should be physic-ecological conditions free of human impact and habitats with minimum or absence of disturbance. It is expected this research is the first step in the dialogue on the feasibility of seeking natural conditions in conservation units of integral protection, knowledge necessary for the framework of these protected areas in the Special Class.

<p>There are two central themes to this thesis. Firstly, it shows how the adoption of people-centered and greening development paradigms, designed to improve mainstream development problems of the late 20^th century, continue to produce unsatisfactory and unsustainable results for intended beneficiaries in the 21^st century. Secondly, it shows how the “intended beneficiaries” use their experiences and their knowledge of the development processes to analyze, explain and voice why it has not worked for them. Their <em>local knowledge</em> illustrates how beneficiaries continue to remain on the “outside” or peripheral to development instead of being equal partners as the people-centered discourse claims.</p> <p>This thesis reviews the development of the Wadi Rum Protected Area (WRPA) in southern Jordan. This development fostered both conservation and tourism projects to assist members of the seven local Bedouin communities or clans whose historical rangelands constitute the protected area. Four significant development decisions and projects are examined to better understand how this development functioned. Many Bedouin commentaries and those of some non-Bedouin involved in the projects provide social, economic and environmental assessments of the protected area's progress over a ten year continuum. What emerges is a nuanced awareness of how the WRPA has not achieved its stated goals or the benefits promised to the Bedouin, but did support other developers', lenders' and government objectives. Bedouin knowledge also highlights how “development” has contributed to a near dissolution of their control over what had been their tourism industry, how it has usurped their control of their lands and villages, how the project has created greater divisiveness between and within the clans and how it has come to support the growth of tourism over environmental protection. In general, the development of the Wadi Rum Protected Area has not achieved its people-centered and green goals.</p> / Doctor of Philosophy (PhD)

The impact of natural disasters is often exacerbated by a disparity between resources for relief and recovery. When the barrio of Punta Santiago in Puerto Rico was devastated by Hurricane Maria in September of 2017, many of its residents lived in the remains of their homes for over a year while they rebuilt from wind damage and flood waters that rose over 6 feet. As climate change leads to an even more constrained timeline for response with increasingly frequent and intense storms, the future of Punta Santiago and other coastal communities worldwide will necessitate strategies ranging from nature-based shore protection systems, coastal setbacks, and managed retreat. This thesis investigates the time disparate processes of disaster relief, recovery, and climate adaptation through the lens of their impact upon the interdependent identities of people and place as informed by theorists and designers including J.B. Jackson and Patrick Geddes. My approach works from the scale of the Antón Ruíz watershed to the delta to uncover the historical and contemporary processes that knit people in the region to the land. I identify commonalities in the immediate recovery needs and long-term resiliency of the community and ecosystems, and seek to support ongoing globally significant research of the rare coastal systems surrounding Punta Santiago. The proposed design, a causeway linking the coast to the hills, dovetails disaster relief and recovery with climate adaptation by providing a persistent connection that restores and reveals the dynamic coastal landscape. / Master of Landscape Architecture / Global warming is correlated with an increase in sea level rise, atmospheric moisture (water content in the air), and surface sea temperatures. The body of research around the complex interaction of these factors is growing, but current projections are that warmer seas will cause more intense hurricanes. Coastal communities, particularly those with fewer economic resources, bear the brunt of this trend and recovery is more difficult with each passing storm. After Hurricane Maria struck in September 2017, many residents of the barrio of Punta Santiago in Puerto Rico lived in the remains of their homes for over a year with little resources to rebuild from the severe wind damage and flood waters that rose over 6 feet. Recovery is still underway almost two years later. A sustainable way forward for Punta Santiago and other coastal communities worldwide necessitates strategies ranging from natural shore stabilization techniques like mangrove buffers and living reefs to restrictions on coastal development, and even the relocation of communities.

The objective of this study was to develop an understanding of the effects of the construction of hydro dams on nearby communities. The construction of the 400 megawatt Bui dam (8o16I 42II N, 2o143I 9 I I W) in Ghana has inundated seven communities and nearly a quarter of Bui National Park, including the destruction of community resources that provide for the livelihood needs of the people living near the dam. The dam led to the resettlement of seven communities, coordinated by the Bui Power Authority. Concerns expressed about the resettlement process indicate some weakness in stakeholder consultations relating to the resettlement, as well as weakness in the development of opportunities to address the anticipated effects of the Bui dam, including effects on community assets. These issues were examined through a study of how the construction of Bui Dam was perceived by local communities representing several ethnic-linguistic groups, including the Ewe, Mo, and Nafana. A mixed methods approach was used in the research, including document analysis, quantitative interviews of 329 households, key informant interviews with 22 households, and case studies of four families, including two families each from resettled and non-resettled communities. Data was obtained from 13 nearby communities, 7 of which had been relocated because of the dam. The study considered examined how the Bui Dam was perceived to influence seven capital assets: cultural; natural; social; human; political; physical; and financial. Overall, people perceive these capital assets to be decreasing in most aspects as a result of the Bui Dam, with some variability among households. This variability was explored through analysis of a number of predictor variables: relocation, ethnicity, livelihood type, age, and gender. Villages not relocated tended to perceive effects less negatively, as did people of Nafana ethnicity, and those who rely mainly on a farming livelihood. Gender and age had little effect: gender mediated effects on some aspects of social and political capital, while age affected only some aspects of cultural capital. Further analysis through the use of multiple regression analysis was undertaken to determine the relative influence of each of these predictor variables. Overall, each multiple regression analysis was significant, with high R squared values ranging from 0.761 to 0.260. The most powerful predictor was whether communities had been relocated or not (“relocate”), which was significantly related to each capital asset, with beta values ranging from 0.826 to 0.418. “Livelihood” was the next most important predictor variable, significantly related to all capital assets and with beta values varying from 0.520 to 0.231. “Ethnicity” was a significant predictor for four of seven capital assets, with beta values ranging from 0.133 to 0.055. “Gender” was a significant predictor variable for two of seven capital assets (social capital, with a beta value of 0.084, and political capital, with a beta value of 0.119). “Age” was a significant variable for just one capital asset (cultural), with a beta value of 0.038. In summary, this study is consistent with other studies that have examined the effect of dams on the livelihoods of nearby communities in that for most households the consequences have been negative, although not as severe for those households that were not forced to relocate, people of Nafana ancestry, or people who rely mainly on farming. The presence of Bui National Park may have moderated these negative effects somewhat, through employment provided in the park; and through ecosystem services such as vegetative cover in the park supporting cloud formation and rain occurrence / Graduate / 0366 / 0534 / 0628 / jonesarthur2002@yahoo.co.uk

84 ABSTRACT This thesis is concerned on the topic "Legal regime of protected areas and protective zones by the water protection." Water like environmental compartment has a key role to the existence of life on Earth. That is the reason for its protection. For achieving this protection could not be protected only this environmental compartment, but it is necessary to focus on other ones, which are related to this protection. The main aim of this thesis is to analyse the situation and the ways of ensuring the territorial water protection, to point out the basic types of them and their similar and different characteristics and provide a comprehensive explication of territorial water protection. For these reasons, the thesis is divided into two parts. The first is dealing with systematization of water protection and water protection relationship as a whole and territorial water protection as one of its important elements. This part is necessary for the orientation and the issue of inclusion territorial water protection to the entire system of water protection. The second part of this thesis at first reflects on the ways of promulgation of types of the territorial water protection and then is directly focused on them. The first type of territorial water protection represents the protected area of natural water...

Integrated coastal and ocean management (ICM) requires new management systems where social learning (SL), the joint and collaborative learning trough interaction, is a key element. The occurrence of SL and the factors that affect it were investigated by documentary analysis, observation of ongoing processes and accessment of the perception of people involved with the participatory management of a marine protected area (MPA) in Brazil. The general hypothesis is that SL can qualify participation and improve ICM. To test it, this research characterized the management of the MPA, identifying SL processes and how they were fostered/hindered, with special attention to the role of research and educational institutions and the promotion of knowledge exchange. SL was evidenced by changes in knowledge, perception of the complexity of the system, social context and in the development of new understandings among the stakeholders involved in the processes, leading to strong social organization, social empowerment and institutional changes, promoting social capital. To improve ICM through SL, five strategies are proposed: promote diverse participation, not limited to official membership; promote simultaneous discussions in small groups; favor interaction processes over rapid solutions; explore common interests; explore different roles, especially with reference to research and educational organizations. / A gestão costeira integrada (GCI) demanda novos sistemas de gestão onde a aprendizagem social (AS), a aprendizagem conjunta e colaborativa que ocorre por meio de interação, é um elemento-chave. A ocorrência de AS e os fatores que a afetam foram investigados por meio de análise documental, observação de processos em andamento e levantamento da percepção dos indivíduos envolvidos com a gestão participativa de uma área marinha protegida (AMP) no Brasil. A hipótese central é que AS pode qualificar a participação e aprimorar a GCI. Esta pesquisa caracterizou a gestão da AMP e identificou processos de AS e como eles foram favorecidos/prejudicados, com atenção especial ao papel de instituições de ensino e pesquisa e à promoção de troca de conhecimento. A AS foi evidenciada por mudanças no conhecimento, percepção da complexidade do sistema, contexto social e construção de entendimentos coletivos, fortalecendo a organização social, empoderamento social e mudanças institucionais, promovendo o capital social. Para aprimorar a GCI por meio de AS são propostas cinco estratégias: promover diversidade de participação; promover a discussão simultânea de vários problemas; favorecer processos de interação à soluções rápidas; explorar interesses comuns; explorar diferentes papéis, especialmente considerando as organizações de ensino e pesquisa.
