A definição de ecoturismo adotada no Brasil é composta, basicamente, por três aspectos: a conservação do meio ambiente, a conscientização ambiental dos visitantes e o envolvimento da comunidade local. A partir desse enfoque, o presente trabalho analisa os resultados das políticas públicas para o desenvolvimento do uso público em Unidades de Conservação. A análise foi realizada por meio do estudo de casos de duas áreas protegidas, o Parque Estadual Turístico Alto do Ribeira (PETAR), localizado no Estado de São Paulo, no Brasil, e o Strathcona Provincial Park, situado na província de British Columbia, no Canadá. O estudo de casos múltiplos se utilizou de duas fontes de evidências, os documentos das políticas públicas identificadas e as entrevistas com os diversos atores envolvidos: poder público, comunidade local e visitantes. A análise dos documentos e das entrevistas foi realizada por meio da técnica de análise de conteúdo, com a utilização de procedimentos objetivos para o estudo dos textos. Inicialmente é apresentada uma revisão bibliográfica sobre políticas públicas, áreas protegidas e uso público, bem como uma descrição de todos os atos normativos identificados sobre uso público em Unidade de Conservação nos dois países e os resultados da análise de conteúdo. Entre os principais resultados, destaca-se que o foco das políticas públicas em atividades mais permissivas, no caso canadense, ou na restrição de atividades, no caso brasileiro, não é preponderante para a conservação do meio ambiente. A política de terceirizações, adotada em British Columbia e que começa a ser implantada em São Paulo, tem impactado de forma mais direta os três aspectos analisados. / The ecotourism definition adopted in Brazil is composed, basically, by three aspects: environmental conservation, environmental awareness of visitors and involvement of local community. From that approach, this study analyzes the results of public policies for public use development inside protected areas. The analysis was accomplished through the case study of two protected areas, Alto Ribeira Tourist State Park (PETAR), located in the State of Sao Paulo, in Brazil, and Strathcona Provincial Park, situated in the province of British Columbia, Canada. The multiple case study was based on two sources of evidence, the identified public policies documents, and interviews with the various stakeholders: government, local community and visitors. The analysis of documents and interviews was performed through the content analysis technique, which uses objective procedures for the text\'s study. Initially a literature review on public policies, protected areas and public use is presented, as well as a description of all identified legal acts on public use in protected areas in both countries, followed by the content analysis results. Among the key findings, it is highlighted that the focus of the policies in permissive activities, as in the Canadian case, or in its restriction, like in Brazil, is not the most significant aspect for the conservation of the environment. The outsourcing policy, already adopted in British Columbia and that starts to be deployed in Sao Paulo, has impacted more directly the three analyzed aspects.

Karst topography is the result of a specific combination of geological conditions, precipitation, biota, and temperature, and is characterized by the gradual solution of the underlying bedrock and the development of underground drainage routes for surficial runoff. Many of these karst landscapes are found in urbanized areas, where the potential for anthropogenic impact is quite high. In many instances, municipalities on karst terrains choose to mitigate these impacts by implementing ordinances that place restrictions on permissible land uses near karst landforms. This dissertation asks the question: are the impacts of karst-related land use regulation on human / social systems significant enough to merit consideration during the regulation writing and implementation process? In the process of answering this question, it is hoped that a broader understanding will be developed of how land use regulations are used to control and regulate human activity on karst lands, particularly (but not exclusively) in the United States; and that the conclusions drawn from that overview might serve as the beginnings of a generally applicable framework for the development of karst regulation.

Connectivity is a major contributor to the overall dynamics of marine populations. However, it still remains challenging to describe connectivity on ecologically meaningful scales of time and space. This is a major impediment to evaluating the impacts of marine protected area with respect to fisheries management objectives. This dissertation brings together a wide array of spatial and connectivity information in the Gulf of Mexico (GOM) with the goal of 1) understanding the spatial distribution of fish populations and source-sink dynamics and 2) evaluating whether this information can be integrated, through a modeling framework, to identify closed areas that could be beneficial to fisheries management in the Gulf of Mexico. First, a generalized additive modelling (GAM) approach is used to describe the distribution of a large number of species groups (i.e. functional groups) across the Gulf of Mexico (GOM) using a large fisheries independent data set (SEAMAP) and climate scale (decades) oceanographic conditions. Next a numerical Lagrangian particle transport model was developed that incorporates two major connectivity processes; site specific larval production and oceanographic transport for an entire large marine ecosystem and over multiple years. The two components are then combined to develop larval dispersal patterns for the entire GOM and identify areas operating as larval sources and sinks. Last, this information is integrated into an end-to-end ecosystem model to evaluate effectiveness of closing source and sink areas for the management of reef fish fisheries. Closed area managemeny simlautions for reef fish indicated closing reef fish source areas, as opposed to sinks, in the GOM is most efficient method of increasing total biomass and yield. However, the impacts across individual functional groups were site specific. Ultimately, these simulations demonstrate the inclusion of connectivity information could improve fishery management objectives in an ecosystem context.

Movement patterns and space use by mature fishes are critical in determining the effectiveness of marine reserves in conserving spawning stock biomass and/or providing biomass to adjacent fisheries through 'spillover'. Home range sizes, activity patterns, site fidelity and habitat preferences were determined for acoustically-tagged snappers and groupers using a rigorously-calibrated array of omnidirectional hydroacoustic receivers deployed in the diverse coral reef environments of a no-take marine reserve (NTMR) network in the Dry Tortugas, Florida. An individual-based localizing tendency model of reef fish movement was parameterized from fine-scale acoustic telemetry data and integrated into a Spatial Management Performance Assessment (SMPA) simulation model for reef fish populations developed to quantitatively evaluate performance of no-take marine reserves in the Dry Tortugas, Florida. Spatially-explicit SMPA models were parameterized for three overfished stocks in the lucrative snapper-grouper fishery: red grouper (Epinephelus morio), black grouper (Mycteroperca bonaci), and mutton snapper (Lutjanus analis). SMPA models were used to evaluate the impacts of a variety of life histories, movement strategies and speeds, and management regulations upon long-term stock sustainability, as measured by annual changes in spawning potential ratio (SPR), and long-term stock productivity, as measured by annual changes in fisheries yield-in-weight per recruit (Yw/R). Under assumptions of constant regional fishing pressure, constant recruitment, and 'realistic' fish movement, SMPA simulation runs from initial conditions in 2000 suggested that by 2014, the Tortugas NTMR network should function to restore red grouper populations to 30% SPR, a Federal management benchmark for sustainability. Mutton snapper were the most mobile of the species investigated; if mutton snapper movements are ignored, their population is predicted to attain 30% SPR by 2014, but given 'realistic' mobility, they may not attain this target by 2021 without additional protections. Black grouper are currently fished at over 9 times sustainable levels. SMPA simulations suggest coupling an increase in minimum size at capture of 20 - 25 cm with NTMR implementation would result in substantial short term losses in yield, but would restore both black grouper and mutton snapper populations to 30% SPR by 2021 and lead to increased long-term yields. Although marine reserve sites are often chosen opportunistically, these findings strongly suggest that reserve designs (e.g. proper sizes and configurations) must take into account the scales and patterns of movement exhibited by the exploited stocks they are intended to protect. These modeling efforts also suggested reserves are not a panacea; in order to promote sustainability for severely depleted stocks, they must be accompanied by an overall reduction in fishing capacity. Although important questions remain concerning the movements of reef fish in response to habitat and density dependent processes, our analyses of realistic reef fish behaviors suggest that the NTMRs of the Dry Tortugas promote substantial gains in SPR, promoting long-term stock sustainability and enhanced egg production. Increased rates of movement diminish these benefits, but may also mitigate short-term losses in yield associated with NTMR establishment.

Co-management agreements for land and resource management can be viewed as emerging forms of a participatory planning model. They strive for equal aboriginal involvement and result not only in more equitable management strategies, but also incorporate aboriginal worldviews and traditional knowledge. This type of planning model is an iterative learning process for all parties involved and is most effective when mechanisms and processes to develop a co-management agreement are situational and contextually appropriate to each location and aboriginal group involved. Co-management agreements should be valued as interim forms that bridge restrictions on and exclusion of aboriginal peoples’ use and influence in relation to land and natural resources, on one side, and complete control through self-government, on the other. This practicum assesses levels of co-management for two case studies by: reviewing relevant literature, analyzing the co-management agreements and plans of management and surveying key personnel at Uluru – Kata Tjuta National Park in Australia and the Gwaii Haanas National Park Reserve and Haida Heritage Site in Canada. The study does conclude that the degree of involvement of aboriginal participation is still wanting, but is higher than it would be if no such framework had been applied. To achieve the full benefits of equality in power distribution, the author suggests that co-management at the highest level should be negotiated either within or as part of land claims agreement or as part of a land title transfer to traditional owners. / October 2005

<p>Marine protected areas (MPAs) are an increasingly prevalent and popular conservation tool, yet there is still much debate over whether they should emphasize the role of expert knowledge or local participation. This debate occurs among an international network of scientists and conservation professionals as well as in relation to particular places and MPAs. This dissertation contributes to an understanding of MPAs by addressing three questions: (1) How do differently situated actors within the MPA social network define and mobilize ideas of knowledge and participation? (2) How are knowledge and participation enacted and perceived in particular MPAs? (3) How do perceptions of knowledge and participation relate to actors' views of the success of MPAs? In order to address these questions, this dissertation presents the results of two separate projects: (1) a survey of international experts at the First International Marine Protected Areas Congress; and (2) an ethnographic study of two marine protected areas and their associated communities and social networks in southern Belize. The results of the survey indicate that the international MPA community is divided in their opinions on what constitutes science and what role scientists should play in the MPA policy process. Scientists who had a positivist view of science were reluctant to engage in MPA policy making, whereas government representatives who held positivist beliefs were more likely to support scientists advocating for particular MPA policies. The results of the ethnographic study in Belize illustrate that multiple groups work to produce, interpret, and contest knowledge for MPA policy, while also engaging in scalar strategies to define what MPAs are, how they should function, and who should be involved in their management. MPA success in Belize is not dependent on either conclusive expert knowledge or positive perceptions of participation, but rather on the accommodation of multiple groups' agendas.</p> / Dissertation

<p>This dissertation consists of four chapters. The first three chapters examine protected areas (or parks) from multiple perspectives. Parks are the first, and often only, line of defense in efforts to conserve biodiversity. Understanding of their promise and problems is necessary to achieve conservation outcomes. Chapter One determines vegetation patterns in and around parks of differing management categories across the Amazon, Congo, South American Atlantic Coast, and West African forests. Within these forests, protected areas are the principle defense against forest loss and species extinctions. In the Amazon and Congo, parks are generally large and retain high levels of forest cover, as do their surroundings. In contrast, parks in the Atlantic Coast forest and West Africa show sharp boundaries in forest cover at their edges. This effective protection of forest cover is partially offset by their very small size: little area is deep inside park boundaries. Compared to West Africa, areas outside parks in the Atlantic Coast forest are unusually fragmented. </p><p>Chapter Two addresses a human dimension of protected areas. Given certain characteristics, parks areas may either attract or repel human settlement. Disproportionate increases in population growth near park boundaries may threaten their ability to conserve biodiversity. Using decadal population datasets, we analyze population growth across 45 countries and 304 parks. We find no evidence for population growth near parks to be greater than growth of rural areas in the same country. Furthermore, we argue that what growth does occur near parks likely results from a general expansion of nearby population centers. Parks may experience unusual population pressures near their edges; indeed, individual case studies provide examples. There is no evidence, however, of a general pattern of disproportionate population growth near their boundaries.</p><p>Chapter Three provides a review of common approaches to evaluating protection's impact on deforestation, identifies three hurdles to empirical evaluation, and notes that matching techniques from economic impact evaluation address those hurdles. The central hurdle derives from the fact that protected areas are distributed non-randomly across landscapes. Matching controls for landscape characteristics when inferring the impact of protection. Applications of matching have revealed considerably lower impact estimates of forest protection than produced by other methods. These results indicate the importance of variation across locations in how much impact protection could possibly have on rates of deforestation.</p><p>Chapter Four departs from the focus of protected areas and instead addresses a more theoretical aspect of community ecology. Ecological theories suggest that food webs might consist of groups of species forming blocks, compartments or guilds. Chapter Four considers ecological networks (subsets of complete food webs) involving species at adjacent trophic levels. Reciprocal specializations occur when (say) a pollinator (or group of pollinators) specializes on a particular flower species (or group of such species) and vice versa. We characterize the level of reciprocal specialization for various classes of networks. Our analyses include both antagonistic interactions (particularly parasitoids and their hosts), and mutualistic ones (such as insects and the flowers that they pollinate). We also examine whether trophic patterns might be palimpsests. That is, there might be reciprocal specialization within taxonomically related species within a network, but these might be obscured when these relationships are combined. Reciprocal specializations are rare in all these systems even when tested using the most conservative null model.</p> / Dissertation

With the rapid development of the coastal environment and advances in fishing technology, marine biodiversity and fishery resources are decreasing dramatically. Therefore, each state is now focusing on conserving the marine environment. Planning Marine Protected Areas is one of the simplest and most efficient ways to do this. In recent years, researches have been conducted on Marine Protected Areas around the world. The government and academic fields in Taiwan also has started to value its surrounding marine environment. However, literature on the Marine Protected Areas in Taiwan has focused on policy and management, not so much on planning and zoning strategies. Therefore, this study uses the Geographic Information System (GIS) to simulate the planning and zoning process. This research set principles and zoning framework for Marine Protected Areas in Taiwan based on case studies and spatial analysis techniques. This study uses Gueishan Island in Yilan County as case study since the unique geographical environment of Gueishan Island provides potentiality to set Marine Protected Areas. In this study, it is suggested that "hot spring resources", "cetacean resources", and "fisheries resources" are the main protected objectives. The zoning strategies, management guidelines and recommendations are provided in this study based on these three protected objectives. According to the GIS simulation process, using the spatial analysis techniques is one of the possible efficient methodologies to plan and zone the Marine Protected Areas. With supplementary data and information, the results can be discussed more specifically in the further study. In addition, techniques of visualization during the MPAs zoning process can be a easier way for various stakeholders to understand, and to strengthen mutual communication, thereby reducing disputes to create successful Marine Protected Areas.

The protection and biodiversity of marine ecosystem become major concerns in the world. Taiwan is also increasingly interested in the establishment of marine protected areas, but it still lack of the scheme on ¡§how to perceive the process for the protected areas¡¨. The establishment of a protected area is all by the top down without a full planning for a proper managed mechanism, evaluation and assessment to the site. The lack of the funds from the government often causes the failure of monitoring and restoration to the protected site. These problems have caused unprovent from imappropiate management to the established protected areas or have made the protected site as a paper park by the administration. This study searches the literatures with regards to the planning processes and the site selection process of marine protected areas in Canada and Australia. The objective of the present study is initiated to determine and survey the problems of marine protected area (MPA) planning in Taiwan. The select sites for the present studies are the proposed MPA site ¡§Four Southern Island¡¨ and other established MPA sites in Penhu. The approaches for assessing the sites include the geographic information system (GIS) spatial analysis method for the aquatic resources and their distributions. Data collections consist of the funding sources for managing the MPA sites and the proposed planning for the delimitation of MPA at the shore areas. The biological information around the sites was assessable for the evaluation process in addition to the management scheme in the future requirement at the Four Southern Islands site. The current expanses supported by the Penhu county government and the Executive Yuan Coast Guard was used for comparing with the proposed budgets needed for the MPA sites. The results showed that the Four Southern Islands has not met with the requirements and guidelines as a MPA due to the lack of scientific survey on the distributions of aquatic species within the proposed 3 nm delimitation. A long-term research and monitoring of the resources shall be performed to evaluate the sites prior to be announced as a designate MPA site. Although local residents agreed positively about the important of MPA site establishment through the questionnaire and interviews, there is still the need to improve management practices and more strict law enforcement capacity to ensure the protection of the marine environment for achieving a sustainable development. The survey results have been made to the process of site selection of marine protected areas according to Canada, suggesting that the current planning of the Four Southern Islands in Penghu does not match the site selection process. There need to be clarified with the details of the implementation process. In the end, above finding may impact the establishment of protected areas, including the relationship between public sector¡¦s responsibilities, and socio-economic conditions of the surrounding area development, marine environment and resources and fishing activities and other aspects of the integration considerations. These are expected to be the important conditions for the recommendations for the MPA site selection and to ensure the sustainable development of marine environment.

Overfishing of stock and decreasing biodiversity are grave concerns for the U.S. and the rest of the world. Understanding and applying spatial and temporal information of marine species’ reproductive ecology and critical life habitat is vital to the development of effective strategies for marine resource management. In the Caribbean, one of the critical science gaps hindering effective management is the lack of information on how environmental factors may make fish spawning aggregation (FSA) sites optimal for spawning. Understanding the patterns of seafloor characteristics of spawning aggregation sites is of great interest to managers who need a means to efficiently design marine protected areas to help rebuild regional fish stocks. The specific goals of the study were: (1) to map the seafloor at historically known grouper and snapper spawning aggregation sites in three different countries, and (2) to characterize quantitatively the geomorphology of the sites including horizontal and vertical curvature profiles of the reefs, bottom depth at spawning sites, distance between spawning sites and shelf-edges/reef promontory tips, and the shortest distance between the spawning sites and 100 m water depth. These data were field-collected with a GPS and single-beam eco-sounder that provided latitude/longitude and depth. The point data were interpolated to surfaces in GIS to determine slope, aspect, curvature, and distance from spawning sites and three-dimensional reef structures. This study revealed that all 12 known Nassau grouper spawning aggregation sites in Belize and 5 known sites in the Cayman Islands were located at convex-shaped seaward extending reefs (reef promontories) jutting into deep water, within 1 km of reef promontory tips. However, spawning aggregations did not always occur at the tips of reef promontories, though all were found along the shelf edges within 1 km of promontory tips. Sixteen sites were multi-species spawning sites. These general characteristics were used to predict an undiscovered multi-species spawning aggregation in Belize. A successful prediction in Belize, together with the compiled data from multiple sites indicate: 1) reef promontories are vital locations for transient reef fish spawning aggregations, and 2) this study provides a potential tool for prediction of unknown spawning sites in the Caribbean.
