Toward Sustainable Management of National Parks in Japan: Securing Local Community and Stakeholder Participation 总被引:4,自引:0,他引:4
Hiwasaki L 《Environmental management》2005,35(6):753-764
Japan’s national park system constitutes a potentially viable mechanism for securing local community participation and building stakeholder consensus for sustainable park management, although the potential of this system is yet to be fully maximized. This article gives an overview of the system of protecting natural resources in Japan, focusing on the national park system. Parks are managed by zoning and regulation, which is unique in that land is not “set aside” for nature conservation, but designated as national park wherever the need to preserve “scenic beauty” has been recognized, regardless of land ownership or land use. Although resource conservation under this system has been problematic, it has advantages, especially in terms of community participation. This article demonstrates that in order to reach the system’s potential, the park authority must act as coordinator of stakeholders and facilitator of bottom-up approaches to decision-making. In order to do this, steps that must be taken include the following: identifying the various stakeholders in park management and defining the “local community”; clarifying the roles and responsibilities of each stakeholder; and supporting consensus-building among stakeholders regarding the objectives and long-term vision of each park. By taking these steps, it would be possible to build a park management system that overrides government boundaries and involves local communities. This will enable the park authority to address the challenges facing Japan’s complex system of conserving natural resources, and move towards sustainable management of natural resources in Japan. 相似文献

Claims of environmental injustice, human neglect, and racism dominated the popular and academic literature after Hurricane Katrina struck the United States in August 2005. A systematic analysis of environmental injustice from the perspective of the survivors remains scanty or nonexistent. This paper presents, therefore, a systematic empirical analysis of the key determinants of Katrina‐induced environmental injustice attitudes among survivors in severely affected parishes (counties) in Louisiana and Mississippi three years into the recovery process. Statistical models based on a random sample of survivors were estimated, with the results revealing significant predictors such as age, children in household under 18, education, homeownership, and race. The results further indicate that African‐Americans were more likely to perceive environmental injustice following Katrina than their white counterparts. Indeed, the investigation reveals that there are substantial racial gaps in measures of environmental injustice. The theoretical, methodological, and applied policy implications of these findings are discussed. 相似文献

The driving forces behind natural resource management (NRM) vary among countries. Most NRM programmes focus on biophysical drivers such as soil, water and vegetation, with little attention directed towards the nuanced sociocultural and religious drivers of sustainable natural resource management (SNRM) practices. This paper explores those understudied drivers that influence local people’s participation (LPP) in SNRM in Isfahan, Iran. Using a multi-stage stratified sampling method, we selected 200 natural resource experts and natural resource users to complete a questionnaire about their perceptions of SNRM. Results reveal that sociocultural and religious beliefs are the major drivers of SNRM. The results also indicate that subsidiary drivers include: a sense of responsibility towards SNRM; the conviction that natural resources belong to God and should therefore be preserved; participation to preserve natural resources because of training courses and media influence; a long-established custom of preserving natural resources; and the specific impact of environmental television programmes. Demographic analysis finds a significant relationship between educational level and LPP in SNRM. This study’s results therefore suggest that natural resource managers would benefit from a deeper understanding of the local sociocultural and religious contexts that motivate people to participate in SNRM. 相似文献

Sapporo Plastics Recycling Co., Ltd., (SPR) started its commercial operation of waste plastics liquefaction in 2000. At first
only hydrocarbon oil was reclaimed, this being derived from the waste plastics liquefaction process under the Japanese Containers
and Packaging Recycling Law. Presently, thermal degradation residue and hydrochloric acid are being produced as by-products
in addition to the hydrocarbon oil. As a result, the SPR plastics liquefaction plant has achieved a high reclamation rate
of 96%, and 93% of the recycled products have been reused in Hokkaido, where SPR is located. The technical problems caused
by corrosion and clogging have been solved.

There is a growing recognition in developing countries that community participation in water and sanitation projects is a
necessary strategy in sustainable development. The main advantage of following such an approach is that, if participation
can encourage a sense of ownership of the projects, the benefits of the project are more likely to extend over the long term.
The case study at hand focuses on the challenges faced in implementing a wastewater treatment system to solve an environmental
and public health problem in a rural community, Rosario de Tesopaco, in northwest Mexico. Until recently, the community has
been unable to implement an effective plan to treat the wastewater generated in the community. The problems faced by the community
can be attributed to the political arrangement of water and sanitation decentralization in Mexico that occurred in the mid
1980’s, whereby communities were required to meet wastewater treatment standards, but were not given the technical and political
guidance needed to achieve this goal. However, in this instance, cooperation between the authorities in Rosario de Tesopaco,
the federal agency for social development, and an academic institution has led to the successful design and approval of a
wastewater treatment project. This achievement can be attributed to the use of an effective collaborative strategy, tailoring
the project to the needs and capacity of the local community, positioning the community as the leaders and owners of the project.
A model for following this strategy for developing rural sanitation projects in Mexico is proposed.

Learning for sustainability: participatory resource management in Cambodian fishing villages 总被引:1,自引:0,他引:1
Considerable attention is now being given to the role and importance of education and learning implications of participatory resource and environmental governance. The contention is that such learning has the potential to transform behaviour, and in the case of resource management, may help change current patterns in resource use towards a more sustainable social-ecological system. Our purpose is to establish the opportunities for learning afforded to those participating in local level resource management committees in two Cambodian fishing communities and consider the learning outcomes from such opportunities. Our approach was qualitative and used a case study design. The findings establish a wide range of committee resource management activities that resulted in both instrumental (e.g., learning about administrative procedures) and communicative (e.g., insights into the need to conserve mangroves) learning. It was revealed that such learning can lead to changes in behaviour at the community level (e.g., managing local waste). Our findings also indicated a number of motivators and enablers of learning such as opportunities for dialogue, leadership and the presence of declining resources. 相似文献

Between 1949 and 1957 Mayak Nuclear Facility locatedin the Chelyabinsk region released some discharges ofradiochemical production wastes into the Techa Riverand Lake Karachay which resulted in an extensivecontamination of large territories with long-livedradionuclides such as 90Sr, 137Cs, and239Pu. Between 1994 and 1996 the research teamof Siberian Medical University conducted thechromosome analysis and the electron-spin resonance(ESR) spectrometry of tooth enamel in theradiation-exposed inhabitants of four settlements inthe Techa River region. We observed significantlyincreased levels of chromosome aberrations in theradiation-exposed inhabitants as compared to thecontrols. The ESR signal intensity and the chromosomeaberration frequency in lymphocytes of the toothdonors showed a good correlation. Moreover, therewas a good correlation between the level ofwhole-body 137Cs activity detected by awhole-body radiation counter and the frequency ofchromosome aberrations among the radiation-exposed inhabitants. The data showed that 15% of theinhabitants of the Muslyumovo settlement received aradiation dose exceeding 100 cGy. The frequency ofchromosome abnormalities reached its peak in thepersons born between 1949 and 1957. We suppose thatradionuclides incorporated in the body are responsiblefor the chromosome aberrations in the inhabitants. 相似文献

This paper describes one example of how the UK National Air Quality Strategy (NAQS) is implemented in a local urban environment. The paper reviews the beginning of this process, by examining the review and assessment procedures of the NAQS in the London Borough of Barnet. By the application of available UK tools of local air quality management (LAQM), the process began through analysis of the levels of local emissions and progressed onto modelling of current and future air quality. A map showing combined emission hotspot areas for the Borough indicated and higher emission rates occur in the south of the Borough and along the major transport corridors, as road sources dominate emissions. Dispersion modelling studies were also conducted for this purpose, using the screening models GRAM, PGRAM and ADMS Urban for an in-depth assessment. These analyses found that some local point sources and the majority of Borough roads with over 20,000 vehicles per day produced exceedances of the future objectives for air quality for some pollutants.Recommendations for the progression of LAQM in the Borough are made and include the update and expansion of the emissions information held for use in future modelling studies. The paper demonstrates the experience of implementing the Strategy, using the tools and procedures available for this purpose, in a local urban environment that is similar to many in the UK. 相似文献
