The role of communication in the management of Nigeria's capture fisheries resources

Development and management indices identified in the capture fishery resources focus on stock management, freshwater and marine pollution by organic and inorganic compounds including silting, plankton sustainability, fishing methods, biological productivity, energy cycles, ornamental fish and sanctuaries. The issue of post-harvest handling and processing is also discussed. The paper also identifies fisheries sectorial problems at the artisanal and industrial level both at sea and at shore, in the processing plant, infrastructure, manpower and marketing issues. The paper suggests that advocacy should be incorporated into extension and communication programme ensuring some changes in attitudes of all stakeholders in the fisheries game. The paper concludes stating that policy makers should stop paying lip-service to the fisheries sub-sector and should create a separate Ministry for Fisheries

Reforming state-level coastal management and development policies: strategic retreat as an innovative, proactive and equitable coastal environmental management strategy

Atlantic and Gulf Coast shorelines include some of the most unique and biologically rich ecosystems in the United States that provide immeasurable aesthetic, habitat and economic benefits. Natural coastal ecosystems, however, are under increasing threat from rampant and irresponsible growth and development. Once a boon to local economies, complex natural forces – enhanced by global climate change and sea level rise - are now considered hazards and eroding the very foundation upon which coastal development is based. For nearly a century, beach restoration and erosion control structures have been used to artificially stabilize shorelines in an effort to protect structures and infrastructure. Beach restoration, the import and emplacement of sand on an eroding beach, is expensive, unpredictable, inefficient and may result in long-term environmental impacts. The detrimental environmental impacts of erosion control structures such as sea walls, groins, bulkheads and revetments include sediment deficits, accelerated erosion and beach loss. These and other traditional responses to coastal erosion and storm impacts- along with archaic federal and state policies, subsidies and development incentives - are costly, encourage risky development, artificially increase property values of high-risk or environmentally sensitive properties, reduce the post-storm resilience of shorelines, damage coastal ecosystems and are becoming increasingly unsustainable. Although communities, coastal managers and property owners face increasingly complex and difficult challenges, there is an emerging public, social and political awareness that, without meaningful policy reforms, coastal ecosystems and economies are in jeopardy. Strategic retreat is a sustainable, interdisciplinary management strategy that supports the proactive, planned removal of vulnerable coastal development; reduces risk; increases shoreline resiliency and ensures long term protection of coastal systems. Public policies and management strategies that can overcome common economic misperceptions and promote the removal of vulnerable development will provide state and local policy makers and coastal managers with an effective management tool that concomitantly addresses the economic, environmental, legal and political issues along developed shorelines.

San Francisco Bay regional sediment management strategy development

The San Francisco Bay Conservation and Development Commission (BCDC), in continued partnership with the San Francisco Bay Long Term Management Strategies (LTMS) Agencies, is undertaking the development of a Regional Sediment Management Plan for the San Francisco Bay estuary and its watershed (estuary). Regional sediment management (RSM) is the integrated management of littoral, estuarine, and riverine sediments to achieve balanced and sustainable solutions to sediment related needs. Regional sediment management recognizes sediment as a resource. Sediment processes are important components of coastal and riverine systems that are integral to environmental and economic vitality. It relies on the context of the sediment system and forecasting the long-range effects of management actions when making local project decisions. In the San Francisco Bay estuary, the sediment system includes the Sacramento and San Joaquin delta, the bay, its local tributaries and the near shore coastal littoral cell. Sediment flows from the top of the watershed, much like water, to the coast, passing through rivers, marshes, and embayments on its way to the ocean. Like water, sediment is vital to these habitats and their inhabitants, providing nutrients and the building material for the habitat itself. When sediment erodes excessively or is impounded behind structures, the sediment system becomes imbalanced, and rivers become clogged or conversely, shorelines, wetlands and subtidal habitats erode. The sediment system continues to change in response both to natural processes and human activities such as climate change and shoreline development. Human activities that influence the sediment system include flood protection programs, watershed management, navigational dredging, aggregate mining, shoreline development, terrestrial, riverine, wetland, and subtidal habitat restoration, and beach nourishment. As observed by recent scientific analysis, the San Francisco Bay estuary system is changing from one that was sediment rich to one that is erosional. Such changes, in conjunction with increasing sea level rise due to climate change, require that the estuary sediment and sediment transport system be managed as a single unit. To better manage the system, its components, and human uses of the system, additional research and knowledge of the system is needed. Fortunately, new sediment science and modeling tools provide opportunities for a vastly improved understanding of the sediment system, predictive capabilities and analysis of potential individual and cumulative impacts of projects. As science informs management decisions, human activities and management strategies may need to be modified to protect and provide for existing and future infrastructure and ecosystem needs.

SAQUA - sistema baseado em software livre para análise do comportamento da qualidade das águas fluviais: aplicado à bacia do rio Paraíba do Sul.

Nesta dissertação foi desenvolvido o sistema SAQUA (Sistema para Análise da Qualidade das Águas Fluviais), que permite o acompanhamento dos dados de séries históricas de parâmetros físico-químicos para análise da qualidade de águas fluviais. A alimentação do sistema SAQUA se dá a partir do arquivo tipo texto gerado no Hidroweb, sistema de banco de dados hidrológicos da ANA (Agência Nacional de Águas), disponibilizado na internet. O SAQUA constitui uma interface que permite a análise espaço-temporal de parâmetros de qualidade da água específicos definidos pelo usuário. A interface foi construída utilizando o servidor de mapas Mapserver, as linguagens HTML e PHP, além de consultas SQL e o uso do servidor Web Apache. A utilização de uma linguagem dinâmica como o PHP permitiu usar recursos internos do Mapserver por meio de funções que interagem de forma mais flexível com códigos presentes e futuros, além de interagir com o código HTML. O Sistema apresenta como resultado a representação gráfica da série histórica por parâmetro e, em mapa, a localização das estações em análise também definidas pelo usuário, geralmente associadas a uma determinada região hidrográfica. Tanto na representação gráfica da série temporal quanto em mapa, são destacados a partir de código de cores a estação de monitoramento e a observação em que os limites estabelecidos na resolução CONAMA 357/05 não foi atendido. A classe de uso da resolução CONAMA que será usada na análise também pode ser definida pelo usuário. Como caso de estudo e demonstração das funções do SAQUA foi escolhida a bacia hidrográfica do rio Paraíba do Sul, localizada na região hidrográfica Atlântico Sudeste do Brasil. A aplicação do sistema demonstrou ótimos resultados e o potencial da ferramenta computacional como apoio ao planejamento e à gestão dos recursos hídricos. Ressalta-se ainda, que todo o sistema foi desenvolvido a partir de softwares disponibilizados segundo a licença GPL de software livre, ou seja, sem custo na aquisição de licenças, demonstrando o potencial da aplicação destas ferramentas no campo dos recursos hídricos.

Controle gerencial em equipes de desenvolvimento de software: um estudo de caso

A tecnologia da informação (TI) transformou o mundo nas últimas décadas e suas contribuições no processamento e disseminação da informação provocaram mudanças radicais no modo de viver das pessoas e afetou profundamente a gestão e a estrutura das organizações. Neste novo cenário, a literatura de negócios vem apresentando registros de desperdício de investimentos na área de tecnologia da informação. As dificuldades em reconhecer valor nos investimentos em TI e os desafios enfrentados na gestão de equipes de desenvolvimento de software são aspectos considerados no problema a ser pesquisado, a saber: a área de TI carece de sistemas de controle gerencial que poderiam minimizar riscos de desperdício de recursos, de baixa produtividade ou de fracasso na implantação do sistema a ser desenvolvido?O objetivo geral desta pesquisa é investigar as dificuldades enfrentadas pelas equipes de desenvolvimento de software para avaliar se há ou não desperdício de recursos, segundo a percepção dos entrevistados e, ainda, se há ou não carência de controle gerencial. Investigar quais poderiam ser os indicadores mais adequados para um sistema de controle gerencial voltados para esta área de atuação da TI e mapear fatores de sucesso estão entre os objetivos específicos da pesquisa. Do ponto de vista metodológico, esta é uma pesquisa exploratória que adota o procedimento de estudo de caso baseado em análise qualitativa. Os resultados alcançados confirmam o problema de desperdício de recursos e de baixa produtividade nas equipes de TI da empresa analisada e apontam para a carência de mecanismos ou processos de controle gerencial.

Gestão de Custos através do Custeio Baseado em Atividades (ABC): um estudo de caso em um projeto de desenvolvimento de software

O contexto da era da informação exige novas habilidades para competir com sucesso, tanto para empresas industriais como para as de serviços. Desde o seu surgimento, a Engenharia de Software tem enfrentado o desafio em estimar, controlar e gerenciar custos no processo de desenvolvimento de software. Os custos são parte de um projeto de software e nem sempre são claramente mensurados. Algumas desenvolvedoras de software são caracterizadas como prestadoras de serviços e as organizações que prestam serviços possuem as mesmas dificuldades em termos gerenciais que as indústrias, elas precisam de sistemas de gestão adequados para gerir seus custos, logo seus recursos. Nesse contexto é que os sistemas de informações contábeis estão inseridos, fornecendo respostas que os gestores necessitam para tomar decisões. Os custos são exemplos desse tipo de informação, pois o seu conhecimento é indispensável para uma boa gerência dos recursos organizacionais. O Custeio Baseado em Atividades (ABC) é uma ferramenta contábil útil para o gerenciamento estratégico dos custos uma vez que os sistemas de custeio tradicionais já não atendem essa necessidade das organizações. Diante desse cenário, o objetivo geral dessa dissertação é aplicar a metodologia de custeio baseado em atividades em um projeto de desenvolvimento de software com a finalidade de gestão de custos. Este pesquisa caracteriza-se como qualitativa descritiva e faz uso do método do estudo de caso. Através desse estudo foi possível comprovar a utilidade do ABC como instrumento de auxílio na gestão de custos nas organizações que prestam serviços em desenvolvimento de software, pois possibilita a visualização da maneira que os recursos são consumidos pelas atividades que agregam e não agregam valor ao negócio e ao cliente.

The different computer softwares developed by the International Center for Living Aquatic Resources (ICLARM) and its functions and uses in fisheries science are presented.

A low-level geographic information system for coastal zone management with applications to Brunei Darussalam: Part III:: simulation and tracking oil spills

B:RUN is a low-level GIS software designed to help formulate options for the management of the coastal zone of Brunei Darussalam. This contribution presents the oil spill simulation module of B:RUN. This simple module, based largely on wind and sea surface current vector parameters, may be helpful in formulating relevant oil spill contingency plans. It can be easily adapted to other areas, as can the B:RUN software itself.

A computer software package for assessing and managing risks posed by experiments with genetically modified fish and shellfish

Assessment and management of risk is needed for sustainable use of genetically modified aquatic organisms (aquatic GMOs). A computer software package for safely conducting research with genetically modified fish and shellfish is described. By answering a series of questions about the organism and the accessible aquatic ecosystem, a researcher or oversight authority can either identify specific risks or conclude that there is a specific reason for safety of the experiment. Risk assessment protocols with examples involving transgenic coho salmon, triploid grass carp and hybrid tilapia are described. In case a specific risk is identified, the user is led to consider risk management measures, involving culture methods, facilities design and operations management, to minimize the risk. Key features of the software are its user-friendly organization; easy access to explanatory text, literature citations and glossary; and automated completion of a worksheet. Documented completion of the Performance Standards can facilitate approval of a well designed experiment by oversight authorities.

A Low-level Geographic Information System for coastal zone management, with applications to Brunei Darussalam: Part I: The concept and its design elements

This contribution is the first part of a four-part series documenting the development of B:RUN, a software program which reads data for common spreadsheets and presents them as low-resolution maps of slates and processes. The program emerged from a need which arose during a project in Brunei Darussalam for a 'low level' approach for researchers to communicate findings as efficiently and expeditiously as possible. Part I provides a overview of the concept and design elements of B:RUN. Part II will highlight results of the economics components of the program evaluating different fishing regimes, sailing distances from ports and fleet operating costs. Environmental aspects will be presented in Part III in the form of overlay maps. Part IV will summarize the implications of B:RUN results to coastal and fishery resources management in Brunei Darussalam and show how this approach can be adapted to other coastlines and used as a teaching and training tool. The following three parts will be published in future editions of Naga, the ICLARM Quarterly. The program is available through ICLARM.

Harmful algal bloom management and response: assessment and plan

This report, "Harmful Algal Bloom Management and Response: Assessment and Plan" reviews and evaluates Harmful Algal Bloom (HAB) management and response efforts, identifies current prevention, control, and mitigation programs for HABs, and presents an innovative research, event response, and infrastructure development plan for advancing the response to HABs. In December 2004, Congress enacted and the President signed into law the Harmful Algal Bloom and Hypoxia Amendments Act of 2004, (HABHRCA 2004). The reauthorization of HABHRCA acknowledged that HABs are one of the most scientifically complex and economically damaging coastal issues challenging our ability to safeguard the health of our Nation’s coastal ecosystems. The Administration further recognized the importance of HABs as a high priority national issue by specifically calling for the implementation of HABHRCA in the President’s U.S. Ocean Action Plan. HABHRCA 2004 requires four reports to assess and recommend research programs on HABs in U.S. waters. This document comprises two linked reports specifically aimed at improving HAB management and response: the Prediction and Response Report and the follow-up plan, the National Scientific Research, Development, Demonstration, and Technology Transfer (RDDTT) Plan on Reducing Impacts from Harmful Algal Blooms. This document was prepared by the Interagency Working Group on Harmful Algal Blooms, Hypoxia, and Human Health, which was chartered through the Joint Subcommittee on Ocean Science and Technology of the National Science and Technology Council and the Interagency Committee on Ocean Science and Resource Management Integration. This report complements and expands upon HAB-related priorities identified in Charting the Course for Ocean Science in the United States for the Next Decade: An Ocean Research Priorities Plan and Implementation Strategy, recently released by the Joint Subcommittee on Ocean Science and Technology. It draws from the contributions of numerous experts and stakeholders from federal, state, and local governments, academia, industry, and non-governmental organizations through direct contributions, previous reports and planning efforts, a public comment period, and a workshop convened to develop strategies for a HAB management and response plan. Given the importance of the Nation’s coastal ocean, estuaries, and inland waters to our quality of life, our culture, and the economy, it is imperative that we move forward to better understand and mitigate the impacts of HABs which threaten all of our coasts and inland waters. This report is an effort to assess the extent of federal, state and local efforts to predict and respond to HAB events and to identify opportunities for charting a way forward.

Data structures and software tools for the computer aided design of control systems: a survey.

CAD software can be structured as a set of modular 'software tools' only if there is some agreement on the data structures which are to be passed between tools. Beyond this basic requirement, it is desirable to give the agreed structures the status of 'data types' in the language used for interactive design. The ultimate refinement is to have a data management capability which 'understands' how to manipulate such data types. In this paper the requirements of CACSD are formulated from the point of view of Database Management Systems. Progress towards meeting these requirements in both the DBMS and the CACSD community is reviewed. The conclusion reached is that there has been considerable movement towards the realisation of software tools for CACSD, but that this owes more to modern ideas about programming languages, than to DBMS developments. The DBMS field has identified some useful concepts, but further significant progress is expected to come from the exploitation of concepts such as object-oriented programming, logic programming, or functional programming.
