  • The aim of this paper is to propose the preservation of buffaloes not only as productive livestock, but also as a part of the biodiversity of wetlands and especially of the Greek wetlands. The water buffalo used to be an integral part of the biodiversity of many Greek wetland ecosystems, enriched their landscape, and provided invaluable services and products to the rural people and to the economy in general. Its total population before the 1950s was over 100,000 animals. Presently, it is found only in four wetland sites in Macedonia and Thrace and in the estuaries of Rivers Gallikos and Axios, with a total population of a few hundred animals. These wetlands are Ramsar Sites. Even this small population is threatened with immediate extinction because of the rapidly changing rural socio-economic conditions and the expansion of cultivated fields into wet meadows. Farmers and consumers are rapidly losing contact with this mammal and its products. This species possesses minimum requirements for treatment and is characterized by the ability of utilizing roughage of variable nutritional value. These factors are promising to render buffalo breeding a valuable branch of the Greek livestock sector, which can also contribute to the maintenance of the wetlands.

  • In 1977, the United States enacted the Magnuson Fishery Conservation and Management Act (MFCMA), which established U.S. Fisheries Conservation Zone (FCZ). The MFCMA grants preference to U.S. harvesters over foreign fleets in the U.S. FCZ. At present, the large stocks of groundfish in the U.S. FCZ off the Alaska coast have been under-utilized in the U.S. domestic market and the fisheries for these groundfish are dominated by foreign fleets. Hence, expected benefits from replacing foreign fisheries by domestic fleets will accrue to the U.S. fishery only by exporting the increased U.S. products to foreign countries. U.S. exports may be dependent on the price levels in the foreign markets raised by the reduced foreign catch from U,S. waters. In this paper, Japanese demand models for Alaska groundfish were estimated. The derived coefficient from the estimated models suggest that a decrease in the Japanese landings from the U.S. FCZ by a thousand metric tons will increase pollock price by 0.017 Yen/kg, cod price by 0.351 Yen/kg, flatfish by 1.074 Yen/kg, and ocean perch by 1.347 Yen/kg in the Japanese market. These results based on percentage would increase 19 percent for pollock price, 11 percent for cod price, 40 percent for flatfish, and 2 percent for ocean perch price.

  • The Long-Term Biodiversity Research Programme (LTBRP) for Mindanao is envisioned to be a collaborative programme of the Philippines. It will be a programmatic research on biodiversity - its status, threats. and conservation and management. The chosen research site is Mt. Malindang in Misamis Occidental of Mindanao. The BRP will support a set of research projects that will generate knowledge on biological and ecological, socio-economic. cultural and policy aspects of biodiversity conservation. It will also enable researchers to develop and try new methods for research on these aspects, separately or crossing boundaries of academic disciplines. Moreover. the BRP will implement support programmes which will provide the linkages of research activities to development issues and needs in the research site. The support programmes will also draw from the research projects, the knowledge that can be lent or immediately available to policy and programme formulation. The support programmes will comprise: human resource development or capability-building; information, education and communication; database; networking; community organizing: and development action. The BRP will be undertaken by a group of academie and research institutions from the Philippines, in partnership with their respective government entities and local government units in Mindanao. The Biodiversity Research Programme (BRP) will comprise a set of research projects to be undertaken by small research teams in the site. Researchable areas have been identified initially through the National Biodiversity Research Agenda. and later enriched in the Participatory Rural Appraisal (PRA) Analysis workshops by the Mindanao researchers and Philippine resource persons. Results of the PRA are presented in the paper.

  • Demand-side Management can be defined as'any utility activity aimed at modifying customers' use of energy to produce desired changes in the utility's load shape'. Customers benefit by being able to control energy costs and improve quality of life and become more productive. Utilities benefit from DSM's value as a resource that enhances asset utilization and reduces both fuel costs and environmental emissions. The scope of DSM includes load management through rate schedules and conservation by improving energy effciency and using electricity consumption effectively. This paper study the DSM resource evaluation and customer behavior analysis todesign the DSM Program plan in response to customer needs. We develop basic system dynamics model to analysis the customer behavior based on a survey research. The DSM Program participants in the Hi- efficiency Inverter, Electric motor and efficient lighting applicancies operating by Conservation program 2002 become the survey objects. DSM resource evaluation evaluate firstt the distribution potentialities of each machine and then forecast the degree of diffusion. We apply the system dynamic approach to simulate the dynamic DSM market situation at the domestic beginning. This model will give the energy Planner the opportunity to create different scenarios for DSM program planning. Also it will lead to increased understanding of the dynamic DSM market

  • This paper is performed to study for the plants ecosystems for the rural community forest of designated as natural monument. In addition, it is also proposed the plan of the rural community forest's conservation and restoration for avoiding to the destroy of indiscriminate development such as land-use, cultivation. The rural community forest is a mirror that reflect the regional culture and history, as well as environment. According to this view, undoubtedly, we need to recognise the formative background of rural community forest, the relations between the environment around and the characteristic of plants ecosystem comprehensively. For the purpose of proposing to the plan of rural village forests' conservation and restoration, therefore, this study is: 1) reviews the previous research and ancient documents, and 2) surveys the vegetation structure and the growing conditions in rural village forest directly.

  • This paper presents a design of urban waterfront park using agricultural reservoir in urban fringe area to meet increasing leisure demand for urban resident and to improve resident's quality of life through preventing the reservoir from urban use after reclamation. The site, Unam-Ji, is located on northern part of Taegu metropolitan area, having 17,791 square meters. We had designed this park from 1997 to 1998. After analyzed such factor as accessibility, current land uses, topography, hydrology, vegetation and landscape, climate, and soil, we constructed basic design scheme and principes such as conservation of natural resources, meeting user's recreation demands, providing opportunities for experiencing natural process, integrating naturalness and amenity of the site, and comfortable place with natural dynamism. Based on these principles, we have designed Unam-Ji waterfront park having intrinsic characteristics of the site, maintaining water quality and ecological restoration and improving water-based recreation opportunities. After evaluation of such criteria of design alternative as land use and circulation, spatial organization, convenience for use of and maintenance, conservation of natural environment, and degree of achieving planning and design goals, and maintaining landscape, we have visualized and formalized waterfront park in design process, which is consisted of four squares-- green square for multiple uses, water-based recreation square, pedestrian roads and decks near waterfront, performance square and fords near waterfront. In conclusion, this waterfront park design contributes to improve quality of urban development through preserving agricultural as an important component of urban water system and provide important planning and design implications in urban open space planning.

  • The purpose of this paper is to estimate economic value of multi-functionality roles including landscape and so on, which grassland in Jeju possesses, using Dichotomous Choice Contingent Valuation Method (DC-CVM). Grassland is life cultural heritance of regional residents in Jeju. It has functions like development of favorable landscapes, maintenance of cultural heritage, and recreation/relaxation. Expectation from regional visitors shows that the existence and inheritance value of grassland is higher than we expected. According to the research that we had done from the people that had agreed to contribute grassland. moreover the public commercial value of grassland was not only $397{\sim}419$ billion won but also it will increase an economic gain in every year in Jeju. Therefore, preserving grassland that has multi-functional roles and values can lead to huge economic value in the future in Jeju. Moreover, farm households which are located in the grassland conservation area would be supported $15{\sim}31$ billion won in every year for grassland conservation but it is only $4{\sim}8%$ of the economic value of grassland i.e. $3,971{\sim}4190$ billion won. Thus, grassland preservation policy and plan can raise green-tour commercial value of Jeju area as a long-term inside measurement. Those will have to be propelled continuously.
