The Network of Tropical Aquaculture Scientists (NTAS) : past, present and future

This article reviews the past, present and future activities of the Network of Tropical Aquaculture Scientists (NTAS), an information network for individual scientists working on tropical aquaculture, especially on genetics, integrated agriculture-aquaculture farming systems and coastal aquaculture of tropical molluscs.

Anticipated impacts of recent political changes on fisheries management in South Africa

South Africa's marine resources are essentially fully exploited and in some cases over exploited. The Government of National Unity has embarked on the ambitious Reconstruction and Development Programme (RDP) to: meet the basic needs; develop the country's human resources; build economy; and democratize the state and society. Although fisheries can only be expected to play a minor role in contributing to RDP, the Programme have a role to play in managing South Africa's living marine resources. The role of RDP in fisheries management is presented together with fisheries management approaches to help achieve the aims of the RDP.

Programa Espacial Brasileiro: militares, cientistas e a questão da soberania nacional

Esta tese versa sobre a análise de um dos grandes projetos tecnológicos do Estado nacional, o PEB, com o intuito de verificar em que medida o Brasil, enquanto País em desenvolvimento e inserido no processo de globalização econômica, tem a possibilidade de autodeterminar um projeto nacional de desenvolvimento relativamente soberano e sustentável, mediante sua capacitação tecnológica em áreas de ponta, como as tecnologias espaciais. Neste ínterim, é discutido o processo de institucionalização da ciência no País e a implantação de um moderno sistema de C&T no Brasil através de uma aliança entre cientistas e militares, culminando com a criação do CNPq em 1951. Apresentamos uma releitura da nossa recente história política e os projetos nacionais de desenvolvimento de que foi alvo o País, formulados pelos grupos sociais mais representativos da sociedade na época estudada, recuperando uma discussão que, estendendo-se por décadas, reservou à questão científica um lugar privilegiado no planejamento do Estado. O período da ditadura militar é especialmente contemplado, considerando-se ter sido esta a fase em que realmente o Programa Espacial Brasileiro sofreu maiores investimentos, conferindo aos militares um papel de destaque no quadro de atores sociais coletivos empenhados no projeto de desenvolvimento do País, destacando as diversas correntes ideológicas em ação dentro das Forças Armadas. Foi analisado o processo de globalização devido ao seu nexo interno e externo com as políticas científicas implantadas ou preconizadas no País. Esse processo, alavancado pela nova dinâmica tecnológica internacional iniciada nos anos 1980, estabeleceu profundos impactos e mudanças na constituição atual da esfera do político. Este é o cenário onde, de nosso ponto de vista, inscreve-se a questão da capacitação científico-tecnológica como variável estratégica em todos os níveis das relações internacionais. A compreensão desta problemática deve ser entendida como parte do cenário mundial que se configurou nas últimas décadas do século XX, tendo no entrelaçamento das dinâmicas científico-tecnológica e a soberania nacional dos Estados uma sinergia diferenciada na reordenação geopolítica contemporânea.

Report of the technical exchange between Thailand and Myanmar fisheries scientists on hilsa

Collaboration between Thailand and Myanmar fisheries scientists with the goal of developing an artificial breeding program to promote a sustainable Hilsa (Tenualosa ilisha) fishery. This report was prepared in Thai by Mr Suttichai Rittitum and translated into English and Burmese by the SEAFDEC Secretariat.

Climate resilience of schools: a case study

Social and political concerns are frequently reflected in the design of school buildings, often in turn leading to the development of technical innovations. One example is a recurrent concern about the physical health of the nation, which has at several points over the last century prompted new design approaches to natural light and ventilation. The most critical concern of the current era is the global, rather than the indoor, environment. The resultant political focus on mitigating climate change has resulted in new regulations, and in turn considerable technical changes in building design and construction. The vanguard of this movement has again been in school buildings, set the highest targets for reducing operational carbon by the previous Government. The current austerity measures have moved the focus to the refurbishment and retrofit of existing buildings, in order to bring them up to the exacting new standards. Meanwhile there is little doubt that climate change is happening already, and that the impacts will be considerable. Climate scientists have increasing confidence in their predictions for the future; if today’s buildings are to be resilient to these changes, building designers will need to understand and design for the predicted climates in order to continue to provide comfortable and healthy spaces through the lifetimes of the buildings. This paper describes the decision processes, and the planned design measures, for adapting an existing school for future climates. The project is at St Faith’s School in Cambridge, and focuses on three separate buildings: a large Victorian block built as a substantial domestic dwelling in 1885, a smaller single storey 1970s block with a new extension, and an as-yet unbuilt single storey block designed to passivhaus principles and using environmentally friendly materials. The implications of climate change have been considered for the three particular issues of comfort, construction, and water, as set out in the report on Design for Future Climate: opportunities for adaptation in the built environment (Gething, 2010). The adaptation designs aim to ensure each of the three very different buildings remains fit for purpose throughout the 21st century, continuing to provide a healthy environment for the children. A forth issue, the reduction of carbon and the mitigation of other negative environmental impacts of the construction work, is also a fundamental aim for the school and the project team. Detailed modelling of both the operational and embodied energy and carbon of the design options is therefore being carried out, in order that the whole life carbon costs of the adaptation design options may be minimised. The project has been funded by the Technology Strategy Board as part of the Design for Future Climates programme; the interdisciplinary team includes the designers working on the current school building projects and the school bursar, supported by researchers from the University of Cambridge Centre for Sustainable Development. It is hoped that lessons from the design process, as well as the solutions themselves, will be transferable to other buildings in similar climatic regions.
