Understanding the Market for Charter and Headboat Fishing Services

Published and unpublished research findings regarding charter and headboat fishing customers from 11 studies were reviewed to provide a marketing data base for operators and to guide further research efforts. Generally, charter/headboat fishing is a male-oriented activity. Customers were between 30 and 55 years of age. Although both groups of anglers considered themselves to be experienced, charterboat anglers had fished for more years. Charter anglers fished more often with their families and headboat anglers more often with their friends. Charterboat anglers reported higher incomes than headboat anglers. Relaxation, having fun, and escaping from daily pressures were generally more important to both groups of anglers than motives relative to catching fish. Most anglers indicated that the skills and performance of the captain and crew contributed heavily to the overall evaluation of their fishing experience. Anglers were more heavily influenced to choose a particular captain or boat by informal advertising methods (i.e., word-of-mouth recommendations, reputation, and visits to the marina) than formal methods (i.e., advertisements, brochures, radio, and television). Charter anglers relied more on word-of-mouth recommendations and headboat customers were more influenced by previous experiences. Implications for further research are discussed.

Uso de web services e softwares livres na disseminação de informações georreferenciadas sobre produtos da floresta amazônica.

Georreferenced information has been increasingly required for the planning and decision-making in different sectors of society. New ways of dissemination of data, such as the Open Geospatial Consortium (OGC) web services, have contributed to the ease of access to this information. Even with all the technological advances in the area of data distribution, there is still low availability of georreferenced data about the Amazon. The goal of the present work is the development of a spatial data infrastructure (SDI), that is, an environment of sharing and use of georreferenced data based on the technology of web services, metadata and interfaces that allow the user easy access to these data. The present work discussess the OGC patterns, the most relevant georeferrenced data servers, the main web clients, and the revolution in the dissemination of georeferrenced data which geobrowsers and web clients offered to regular users. Data to be released for the case study come from the project Exploitation of Non-wooden Forest Products-PFNM-in progress at the National Institute of Research in the Amazon-INPA-as well as from inventories of NGOs and other government bodies. Besides contributing to the enhancement of PFNM, this project aims at encouraging the use of GIS in the state of Amazonas offering tech support for the deployment of geographic databases and sharing between agencies, optimizing the resources applied in this area through the use of free software and integration of diffuse information currently available.

A segunda residência como indutora da urbanização, na contemporaneidade, em Itapema SC

O fenômeno da segunda residência tem implicações espaciais que interferem na produção e consumo do espaço geográfico. A segunda habitação, vista à luz da prática do lazer e do turismo, atividades cada vez mais praticadas na sociedade contemporânea, implica em interesses, articulações e conflitos no espaço urbano litorâneo. O objetivo do trabalho é caracterizar a segunda residência como indutora do processo de urbanização, na contemporaneidade, no município de Itapema, no litoral norte de Santa Catarina. A segunda residência se caracteriza como um alojamento turístico ou particular usado temporariamente com objetivo de lazer e uso do tempo livre. Assim percebe-se o caráter da propriedade, da finalidade, da temporalidade e do vínculo referente ao domicílio e ao lugar como critérios para determinar uma segunda residência. As particularidades do litoral de Santa Catarina atraíram habitações de segunda residência para atividades de lazer e veraneio, desde a década de 1920. A cidade de Itapema seguiu esta tendência de ocupação. A burguesia industrial de cidades do Vale do Itajaí passou a manter sua residência de veraneio, identificada como segunda residência. Neste contexto, o questionamento central é como o fenômeno da segunda residência contribuiu para o processo de urbanização e a produção do espaço em Itapema? Segundo dados dos Censos Demográficos do IBGE, no ano de 1991 havia 6.408 residências de uso ocasional em Itapema. No ano 2000 este número saltou para 11.142 residências. E finalmente em 2010 chegamos à marca de 13.547 domicílios particulares usados como segunda residência. Em vinte anos houve um aumento de 111 % no número de residências particulares de uso ocasional no município de Itapema. Isto evidencia o caráter de intensa urbanização ligado a segunda residência que tem como padrão a verticalização e o adensamento urbano nos bairros Centro e Meia Praia. A alteração da dinâmica urbana no município de Itapema está diretamente relacionada à urbanização pela segunda residência que, articulada e promovida pelos agentes imobiliários associados ao Estado, aumentou a oferta de empregos e serviços na cidade. Isso levou a um aumento gradativo da população residente nas últimas décadas (ano 2000: 25.869 hab.; ano 2010: 45.797 hab.). As temporadas de verão continuam alterando significativamente o ritmo da cidade. Contudo, a partir da década de 2000 a cidade concentra atividades de comércio e serviços ao longo de todo ano. Assim, há intensa pressão sobre a infraestrutura urbana e a legislação que regula o crescimento da cidade

Transformações territoriais em Macaé decorrentes das atividades petrolíferas

A pesquisa tem por objetivo investigar as implicações da atividade petrolífera em Macaé-RJ. A instalação de empresas e a geração de empregos modificou a dinâmica populacional do município e região, atraindo migrantes e aumentando a urbanização e sua orientação. O aumento financeiro do orçamento municipal a partir das atividades petrolíferas reestruturou a economia, que antes era baseada nas atividades sucroalcooleira, agropecuária, pesca e comércio, para atividades industriais e prestação de serviços, comércio, turismo de negócios. Essas mudanças tornaram o município dependente da atividade petrolífera. As transformações ocorreram não apenas no distrito sede de Macaé, mas também nos outros distritos, que tiveram um aumento populacional, diminuição da atividade agrícola, intensificação das relações campo-cidade. A potencialidade turística da região serrana de Macaé é grande, mas pouco aproveitada, exceto no Sana. A pesquisa analisa essa potencialidade como forma de fortalecimento do rural. O trabalho é apresentado a partir de análise bibliográfica e trabalho de campo. Por fim, a dissertação considera que as implicações da atividade petrolífera em Macaé atingiram primeiramente e intensamente o distrito sede, expandindo-se também para os outros distritos e sua área rural, provocando transformações no setor agrário em direção a um novo rural ou de urbanidades no rural

The EBM-DPSER conceptual model: integrating ecosystem services into the DPSIR framework

There is a pressing need to integrate biophysical and human dimensions science to better inform holistic ecosystem management supporting the transition from single species or single-sector management to multi-sector ecosystem-based management. Ecosystem-based management should focus upon ecosystem services, since they reflect societal goals, values, desires, and benefits. The inclusion of ecosystem services into holistic management strategies improves management by better capturing the diversity of positive and negative human-natural interactions and making explicit the benefits to society. To facilitate this inclusion, we propose a conceptual model that merges the broadly applied Driver, Pressure, State, Impact, and Response (DPSIR) conceptual model with ecosystem services yielding a Driver, Pressure, State, Ecosystem service, and Response (EBM-DPSER) conceptual model. The impact module in traditional DPSIR models focuses attention upon negative anthropomorphic impacts on the ecosystem; by replacing impacts with ecosystem services the EBM-DPSER model incorporates not only negative, but also positive changes in the ecosystem. Responses occur as a result of changes in ecosystem services and include inter alia management actions directed at proactively altering human population or individual behavior and infrastructure to meet societal goals. The EBM-DPSER conceptual model was applied to the Florida Keys and Dry Tortugas marine ecosystem as a case study to illustrate how it can inform management decisions. This case study captures our system-level understanding and results in a more holistic representation of ecosystem and human society interactions, thus improving our ability to identify trade-offs. The EBM-DPSER model should be a useful operational tool for implementing EBM, in that it fully integrates our knowledge of all ecosystem components while focusing management attention upon those aspects of the ecosystem most important to human society and does so within a framework already familiar to resource managers.

National summary of NOAA's shallow-water benthic habitat mapping of U.S. coral reef ecosystems

Coral reef ecosystems are some of the most complex and important ecosystems in the marine environment. They are also among the most biologically diverse and economically valuable ecosystems on earth, producing billions of dollars in food, as well as providing a suite of ecological services, such as recreation and tourism activities and coastal protection from storm and wave action. Yet, despite their value and importance, these fragile ecosystems are declining at an alarming rate (Waddell and Clarke (eds.) 2008) due to a myriad of threats both natural and manmade, including climate change, fishing pressure, and runoff and sedimentation. In response, the Unites States Coal Reef Task Force was established in 1998 by Presidential Executive Order 13089 to lead U.S. efforts to preserve and protect the nation’s coral reef ecosystems. In order to better understand the current state of coral reef ecosystems and successfully mitigate the impacts of stressors, informational products, such as benthic (or sea floor) habitat maps, are critical. Benthic habitat maps support the ability to prioritize areas for further study and protection, and offer a baseline to evaluate the changes in ecosystems over time. In 2000, the United States Coral Reef Task Force charged NOAA with leading federal efforts to produce comprehensive digital maps of all U.S. shallow-water (approximately 0 to 30 m in depth) coral reef ecosystem habitats.

Shallow-water benthic habitats of St. John, U.S. Virgin Islands

Coral reef ecosystems of the Virgin Islands Coral Reef National Monument, Virgin Islands National Park and the surrounding waters of St. John, U.S. Virgin Islands are a precious natural resource worthy of special protection and conservation. The mosaic of habitats including coral reefs, seagrasses and mangroves, are home to a diversity of marine organisms. These benthic habitats and their associated inhabitants provide many important ecosystem services to the community of St. John, such as fishing, tourism and shoreline protection. However, coral reef ecosystems throughout the U.S. Caribbean are under increasing pressure from environmental and anthropogenic stressors that threaten to destroy the natural heritage of these marine habitats. Mapping of benthic habitats is an integral component of any effective ecosystem-based management approach. Through the implementation of a multi-year interagency agreement, NOAA’s Center for Coastal Monitoring and Assessment - Biogeography Branch and the U.S. National Park Service (NPS) have completed benthic habitat mapping, field validation and accuracy assessment of maps for the nearshore marine environment of St. John. This work is an expansion of ongoing mapping and monitoring efforts conducted by NOAA and NPS in the U.S. Caribbean and replaces previous NOAA maps generated by Kendall et al. (2001) for the waters around St. John. The use of standardized protocols enables the condition of the coral reef ecosystems around St. John to be evaluated in context to the rest of the Virgin Island Territories and other U.S. coral ecosystems. The products from this effort provide an accurate assessment of the abundance and distribution of marine habitats surrounding St. John to support more effective management and conservation of ocean resources within the National Park system. This report documents the entire process of benthic habitat mapping in St. John. Chapter 1 provides a description of the benthic habitat classification scheme used to categorize the different habitats existing in the nearshore environment. Chapter 2 describes the steps required to create a benthic habitat map from visual interpretation of remotely sensed imagery. Chapter 3 details the process of accuracy assessment and reports on the thematic accuracy of the final maps. Finally, Chapter 4 is a summary of the basic map content and compares the new maps to a previous NOAA effort. Benthic habitat maps of the nearshore marine environment of St. John, U.S. Virgin Islands were created by visual interpretation of remotely sensed imagery. Overhead imagery, including color orthophotography and IKONOS satellite imagery, proved to be an excellent source from which to visually interpret the location, extent and attributes of marine habitats. NOAA scientists were able to accurately and reliably delineate the boundaries of features on digital imagery using a Geographic Information System (GIS) and fi eld investigations. The St. John habitat classification scheme defined benthic communities on the basis of four primary coral reef ecosystem attributes: 1) broad geographic zone, 2) geomorphological structure type, 3) dominant biological cover, and 4) degree of live coral cover. Every feature in the benthic habitat map was assigned a designation at each level of the scheme. The ability to apply any component of this scheme was dependent on being able to identify and delineate a given feature in remotely sensed imagery.
