Genetic improvement and effective dissemination: keys to prosperous and sustainable aquaculture industries

There is an increasing demand for fish in the world due to a growing population, better economic situation in some sectors, and greater awareness of health issues in relation to food. Since capture fisheries have stagnated, fish farming has become a very fast growing food production system. In this presentation, the author gives an overview of the technologies that are available for genetic improvement of fish, and briefly discuss their merit in the context of a sustainable development. He also discusses the essential prerequisites for effective dissemination of improved stock to farmers. It is concluded that genetic improvement programs based on selective breeding can substantially contribute to sustainable fish production systems. Furthermore, if such genetic improvement programs are followed up with effective dissemination strategies, they can result in a positive impact on farmers' incomes.

Simulierte Auswirkungen des mehrjährigen Bewirtschaftungsplans für die Dorschfischerei in der westlichen Ostsee und die Möglichkeit einer technischen Alternative

The cod stock in the Western Baltic Sea is assessed to be overfished regarding the definitions of the UN World Summit on Sustainable Development at Johannesburg in 2002. Thus, the European Fisheries Council enforced a multi-annual management plan in 2007. Our medium term simulations over the future 10 years assume similar stock productivity as compared with the past four decades and indicate that the goals of the management plan can be achieved through TAC and consistent effort regulations. Taking account of the uncertainty in the recruitment patterns, the target average fishing mortality of age groups 3 – 6 years of F = 0.6 per year as defined in the management plan is indicated to exceed sustainable levels consistent with high long term yields and low risk of depletion. The stipulated constraint of the annual TAC variations of ±15% will dominate future fisheries management and implies a high recovery potential of the stock through continued reductions in fishing mortality. The scientific assessment of sustainable levels of exploitation and consideration in the plan is strongly advised, taking account of uncertainties attributed to environmental and biological effects. We recommend our study to be complemented with economic impact assessments including effects on by-catch species, which have been disregarded in this study. It is further demonstrated, that the goals of the management plan can alternatively be achieved by mesh size adaptations. An alternative technical option of mesh size increases to realize the required reductions in fishing mortality provides avoidance of discards of undersized fish after a few years by means of improved selectivity, another important element of the Common Fisheries Policy. However, it is emphasized that technical regulations since 1990 failed to affect the by-catch and discards of juvenile cod. In any way, the meaningful implementation of the multiannual management plan through stringent control and enforcement appears critical.

Contribuição para o planejamento brasileiro de exploração de petróleo e gás natural através da formulação de uma política nacional de uso sustentável das reservas de petróleo e gás natural

Petróleo e gás natural são recursos naturais não renováveis que possuem grande participação na matriz energética mundial e tendência de crescimento na matriz nacional, cujo marco regulatório limita-se a definir critérios técnicos e procedimentais sem incorporar o modelo de sustentabilidade instituído pela Constituição Federal de 1988. A natureza finita dos recursos não renováveis, como o petróleo e o gás natural, exige uma visão do planejamento de sua exploração de longo prazo na definição dos objetivos e metas. Essa perspectiva de longo prazo traduz uma das preocupações do desenvolvimento sustentável: a garantia de direitos para as futuras gerações. Assim, ao procurar fornecer elementos para a tradução do modelo de desenvolvimento sustentável no arcabouço institucional e legal da indústria petrolífera vigente no Brasil, o presente trabalho busca contribuir para o aprimoramento da regulação petrolífera nacional e a qualidade de vida das gerações presentes e futuras. E, mais do que propor a elaboração de um projeto de lei, como modalidade de implantação de uma política pública, queremos contribuir para o fortalecimento das práticas e ações governamentais voltadas para a aplicação do desenvolvimento sustentável, consoante apregoa a Constituição Federal brasileira. Trata-se aqui de demonstrar, através de metodologia quali-quantitativa, a tese de que é possível incorporar o princípio constitucional de desenvolvimento sustentável na atividade de exploração e produção de petróleo e gás natural, formulando uma política pública que incorpore, no regime de propriedade do petróleo, a variável ambiental e o uso intergeracional que já haviam sido e continuam sendo aplicados a algumas fontes renováveis de energia. Inicialmente, identificamos a composição da matriz energética brasileira desde a inserção do petróleo como uma questão de Estado a partir dos anos 50 do século XX. Em seguida, analisamos a concepção legal e doutrinária para propor, então, a conceituação de um modelo de desenvolvimento energético sustentável, estruturante para a proposição de uma política nacional para a indústria petrolífera. Com base nessa conceituação, analisamos o marco regulatório e os procedimentos institucionais praticados atualmente para identificar as lacunas existentes no ordenamento a serem supridas pela política nacional proposta. A partir da análise dos contextos legal e institucional, e das políticas energética e ambiental, propomos a tradução de conceitos, objetivos, princípios e instrumentos num projeto de lei de Política Nacional de Uso Sustentável das Reservas de Petróleo e Gás Natural. Concluímos tecendo considerações gerais e específicas sobre a proposição aqui formulada com vistas ao aprimoramento do modelo nacional de gestão de recursos energéticos e ao fomento das discussões voltadas para a sustentabilidade das políticas públicas e as práticas privadas enraizadas na exploração irracional de recursos não renováveis

Artisanal fisheries status and sustainable management options in Teknaf coast, Bangladesh

The study was an endeavor to bring forward a concise, factual description of the salient features of the present status of artisanal fisheries resources and its management for sustainable development of fishing communities in Teknaf coast, Cox’s Bazar, Bangladesh. This study was conducted through 14 fishing villages of 4 Unions in Teknaf Upazila. As a hub of various fisheries deeds, a comprehensive coastal fisheries census, conducted on the coast during the study period, revealed that about 566 fishing fleet of two types, 1263 fishing gears of seven kinds, 6466 fishermen were being involved in fishing at Naaf river estuary. The catch composition of the coastal fishing was found 52 finfish species, 10 shrimp and 3 crabs. The unique potentialities provided by mostly affluent fisheries resources are needed to be tapped and channelized in the appropriate direction for maintaining a paragon of these fisheries resources of coastal area and for pursuing ecologically sustainable development via environment friendly intrinsic exploration and exploitation. “Community Based Fisheries Co-management” program should initiate immediately for the fisherman community of Naaf river estuary of Teknaf coastal region. This will go along way to help sustain the coastal fisheries resources with active participation of the fishermen

Meso-scale transboundary units for the management of coral reefs in the South China Sea area

Local communities and local government units are recognized as the primary stakeholders and participants in the management of coral reef resources and the primary beneficiaries of small-scale fishing activities in the nearshore areas of the coastal zone. The issues relating to the management of the coastal zone are multi-faceted and some issues are largely intertwined with national policy and development goals. Thus, national governments have jurisdiction over these nearshore coastal resources to harmonize policies, monitor resource use and provide incentives for sustainable use. However, the natural boundaries of these reef resources, the processes that support reef ecosystems, and the local or national affiliation of the people who benefit from them may transcend the boundaries of the local and national management units. Therefore, efforts to arrest the decline in fish catch and loss of biodiversity for reefs require management interventions and assessment activities to be carried out at varying scales. In Southeast Asia, some aspects of reef and reef resources management — particularly in deciding the allocation of catch among competing fisheries, development of sustainable harvest strategies, use of broodstock for restocking or stock enhancement programs, protection of nursery and spawning areas, designation of systems of marine protected areas, and the identification of representative, adequate and comprehensive areas for biodiversity conservation in the region — may require the definition of larger management units. At the regional level, multi-country initiatives will need to define units for the transboundary management of resources. The use of large marine ecosystems (LMEs) to identify and manage fisheries resources may be a starting point; however, given the relatively sedentary nature of coral reef-dwelling and reef-associated organisms compared with other pelagic and demersal species, meso-scale transboundary units within the LMEs have to be defined. This paper provides suggestions for transboundary management units for coral reef and reef-associated resources in Southeast Asia based on information from genetic structures of model organisms in the region. In addition, specific reef areas are identified, which may be important beyond their national boundaries, as potential sources of recruits.

Nova sociabilidade do capital e a natureza das políticas para jovens trabalhadores no governo Lula: uma análise da participação cidadã do ProJovem Urbano

Fruto das mudanças realizadas no Programa Nacional de Inclusão de Jovens ProJovem, criado em 2005, o ProJovem Urbano é o programa do governo federal destinado a proporcionar o aumento da escolaridade, qualificação profissional inicial e a participação cidadã de jovens de 18 a 29 anos, prioritariamente aqueles que se encontram em maior estado de vulnerabilidade social. Entendendo-o de forma integrada às políticas de alívio à pobreza e à política novo desenvolvimentista implementadas durante o governo Lula, o presente estudo analisou os nexos existentes entre o ProJovem Urbano e a educação para o desenvolvimento sustentável do novo milênio proposta na Política de Desenvolvimento do Milênio e nas orientações dos organismos internacionais, na qual a educação adquire um novo papel: produzir não só capital humano, mas também capital social. A pesquisa centrou-se em uma das dimensões curriculares do programa denominada participação cidadã, que tem entre suas atividades o Plano de Ação Comunitária (PLA) - ação social a ser planejada e executada pelos jovens no intuito de levá-los a resolução de alguns problemas locais. A partir da pesquisa empírica realizada nas cidades de Palmas, São Vicente e Guarujá, nosso objetivo foi identificar o sentido dado à participação e as contradições que essas experiências podem suscitar. Se elas contribuem para ação dos jovens no sentido oposto ao associativismo colaboracionista aos interesses do capital e para a constituição de comportamentos políticos capazes de (re)fortalecer os movimentos sociais progressistas organizados. Com base no método do materialismo histórico e dialético, concluímos que a dimensão ético-político do programa constitui em formar os jovens para a nova sociabilidade capitalista; tanto no plano econômico, ao educar para os valores do novo desenvolvimentismo centrado no consumo, quanto no plano político, por meio do consentimento passivo/ativo aos ajustes executados pelos intelectuais orgânicos do capital na virada do milênio, com a finalidade de abrandar os efeitos da ortodoxia neoliberal. Que não cabe a programas como o ProJovem Urbano a formação da cultura política participativa que venha contribuir para o (re)fortalecimento dos movimentos sociais. E que, apesar das ações comunitárias serem conduzidas pela perspectiva do capital social, na prática, esta ideologia também não é tão facilmente permeável aos jovens participantes do programa das cidades investigadas, frente às suas precárias condições de existência e reprodução da vida, o que faz com que o programa permaneça fortemente em disputa para ser redirecionado ou superado

Production planning of multi-stage multi-option seru production systems with sustainable measures

With the concerns over climate change and the escalation in worldwide population, sustainable development attracts more and more attention of academia, policy makers, and businesses in countries. Sustainable manufacturing is an inextricable measure to achieve sustainable development since manufacturing is one of the main energy consumers and greenhouse gas contributors. In the previous researches on production planning of manufacturing systems, environmental factor was rarely considered. This paper investigates the production planning problem under the performance measures of economy and environment with respect to seru production systems, a new manufacturing system praised as Double E (ecology and economy) in Japanese manufacturing industries. We propose a mathematical model with two objectives minimizing carbon dioxide emission and makespan for processing all product types by a seru production system. To solve this mathematical model, we develop an algorithm based on the non-dominated sorting genetic algorithm II. The computation results and analysis of three numeral examples confirm the effectiveness of our proposed algorithm. © 2014 Elsevier Ltd. All rights reserved.

Epidemiological and nutrition transition in developing countries: impact on human health and development

Whereas common infectious and parasitic diseases such as malaria and the HIV/AIDS pandemic remain major unresolved health problems in many developing countries, emerging non-communicable diseases relating to diet and lifestyle have been increasing over the last two decades, thus creating a double burden of disease and impacting negatively on already over-stretched health services in these countries. Prevalence rates for type 2 diabetes mellitus and CVD in sub-Saharan Africa have seen a 10-fold increase in the last 20 years. In the Arab Gulf current prevalence rates are between 25 and 35% for the adult population, whilst evidence of the metabolic syndrome is emerging in children and adolescents. The present review focuses on the concept of the epidemiological and nutritional transition. It looks at historical trends in socio-economic status and lifestyle and trends in nutrition-related non-communicable diseases over the last two decades, particularly in developing countries with rising income levels, as well as the other extreme of poverty, chronic hunger and coping strategies and metabolic adaptations in fetal life that predispose to non-communicable disease risk in later life. The role of preventable environmental risk factors for obesity and the metabolic syndrome in developing countries is emphasized and also these challenges are related to meeting the millennium development goals. The possible implications of these changing trends for human and economic development in poorly-resourced healthcare settings and the implications for nutrition training are also discussed.

The comparative advantage of the public sector in the development of urban water supply

This paper addresses the potential of public water operations in achieving developmental goals such as the Millennium Development Goals, and argues that the public sector has a comparative advantage in developing water services. The global importance of the public sector in urban water supply is examined through a review of current practice in the world's largest cities, including operational presence and distribution and ongoing trends. Empirical evidence shows that, in transition and developing countries, public operators are capable of undergoing successful reform. One explanatory factor is proposed to be the creation through the public sphere of highly interconnected networks among stakeholders. Such accountability networks act as vehicles for the generation and distribution of public knowledge among stakeholders, which in turn inform rational decision making on the reform and management of operations.
