Sustainable utilization of inland water resources: an integrated program for research and management

In both developed and developing countries, there is increased competition for water resources, resulting in deficiencies in supply and in various forms of pollution. In developing countries, the nutritional potential of aquatic resources is very important. To realize this potential, integrated research and management for sustainable water resource use are needed. This requires a sound understanding of the structure and function of aquatic ecosystems. A programme is presented which stresses the interrelationships of the physical, chemical and biological components of aquatic systems and their catchments. The programme consists of 16 stages in 5 phases, which are as follows: System description; System functioning and modelling; Resource assessment/dynamics; Resource potential; and, Resource utilization for sustainability. This programme enables workers within different disciplines to identify how their expertise contributes to the overall research requirements to support resource development.

Integrated rice-prawn farming in the Mekong Delta, Vietnam: a route towards sustainable and profitable farming systems?

Economic analysis and performance of the integrated rice-prawn farming systems in the Mekong Delta (Vietnam) are reviewed, including the problems and constraints of this integrated system technology.

Economic policies and the sustainable development of coastal resources in the Philippines

The link between environmental trends and economic policies is examined. The assessment of the past and present economic policies affecting the use of coastal resources in the Philippines showed that these policies have accelerated the rate of degradation of coastal resources. The current situation demands not only the reorientation of economic policies, but also other related actions to attain sustainable development of coastal resources.

Rice-fish-vegetable integrated farming: towards a sustainable ecosystem

An outline is given of procedures to take in order to adopt an integrated rice-fish-vegetable farming system in India. Vegetables, which are cultivated in the dikes of the system, may include Luffa acutangula, Vigna unguiculata and Phaseolus vulgaris . When the water depth of the field rises to 30-40 cm, fish fingerlings (Puntius javanicus, Cyprinus carpio and Labeo rohita ) and prawn juveniles (Macrobranchium rosenbergii ) may be stocked. The advantages of such a system are listed and include year round employment opportunities for the farm family and improved farm family income and nutrition.

Economic evaluation of marine fisheries in India for sustainable production and coastal zone development

The article highlights briefly the economics of different types of fishing units operating along the Indian coast; analyzes the exploitation trend of major marine fishery resources in relation to its potential yield; and suggests policy measures for optimum exploitation of resources, conservation and management.

A concretização de políticas públicas na área cultural como garantia de efetiva concessão de direitos sociais

O estudo propõe uma reflexão sobre o Direito à Cultura sob a ótica dos Direitos Fundamentais por meio de uma abordagem contextualizada com as formas em que este direito, seja pelo enfoque individual, seja pelo aspecto coletivo, se concretiza e com as atuações estatais que contribuem para tanto em um cenário de prevalência do modo de vida urbano não só nas cidades, mas também em comunidades outrora tidas como rurais, mas que absorvem progressivamente o modo de vida urbano. A Constituição Federal reconhece amplamente os Direitos Culturais, tendo-os como direitos imprescindíveis para a dignidade da pessoa humana em uma vida em sociedade, mas também impondo ao Poder Público que articule as Políticas Públicas proporcionando instrumentos para que as relações sociais desenvolvam-se em um ambiente de respeito à diversidade cultural e de fomento às manifestações culturais, por ver nelas um patrimônio do povo brasileiro e um espaço de exercício da personalidade de cada indivíduo. Para tanto, a dissertação apresenta uma ampla pesquisa sobre a legislação relacionada com o setor e mostra como estas Políticas Públicas podem estimular a Economia da Cultura em prol de um novo modelo de desenvolvimento, mais sustentável do que o paradigma industrial apresenta.

Low cost light traps for coral reef fishery research and sustainable ornamental fisheries

Two relatively inexpensive light traps to capture pre-settling reef fish and invertebrates are described. A trap made from a plastic bucket (with plastic bottles, a small plastic waste bin and two sheets of plywood) that costs US$15 appears to be just as effective as a large aluminium and plexiglass trap that costs US$275.

Application of Marine Protected Areas for Sustainable Production and Marine Biodiversity off Alaska

Fisheries managers have established many marine protected areas (MPA’s) in the Federal and state waters off Alaska to protect ecological structure and function, establish control sites for scientific research studies, conserve benthic habitat, protect vulnerable stocks, and protect cultural resources. Many MPA’s achieve multiple objectives. Over 40 named MPA’s, many of which include several sites, encompass virtually all Federal waters off Alaska and most of the state waters where commercial fisheries occur. All of the MPA’s include measures to prohibit a particular fishery or gear type (particularly bottom trawls) on a seasonal or year-round basis, and several MPA’s prohibit virtually all commercial fishing. Although the effectiveness of MPA’s is difficult to evaluate on an individual basis, as a group they are an important component of the management program for sustainable fisheries and conserving marine biodiversity off Alaska.

Singapore's biomedical science sector development strategy: is it sustainable?

This paper outlines the strategic efforts undertaken by Singapore to establish its national capability in the biomedical science sector, reviews the commercial base as a result of these efforts and compares Singapore's approach to the UK and the US development models, discusses the challenges that Singapore faces and raises some questions on the long term sustainability of the sector.
