/ The search for sustainable development provides the impetus forexamining the role of indigenous institutions and their ecological knowledgein environmental assessment and local sustainability. This paper attempts totrace the evolution of environmental assessment in Ghana. Focusing on theAshanti Region, the paper further discusses the nature and operations ofindigenous institutions, their ecological knowledge, beliefs, practices, andsocial norms that are relevant to environmental assessment process in thecountry. Some of the challenges that emerge from the discussions arehighlighted. There is a need to establish environmental assessment andcooperative management boards that would include representatives ofindigenous institutions. In addition, the introduction of technicaldictionaries and training manuals based on indigenous ecological knowledgeand their humane environmental practices will further improve theenvironmental assessment process in Ghana.KEY WORDS: Environmental assessment; Indigenous institutions; Indigenousecological knowledge; Sustainable development; Environmental assessmentboards 相似文献

Integration of Environmental Assessment into the Regional Development Planning Process of the Galilee 总被引:2,自引:0,他引:2
/ The Galilee region on the northern edge of Israel constitutes more than 15% of the state's territory, supplies more than half of its drinking water needs, and is an important recreational resource and destination for Israelis. One of the main objectives of the plan for the Galilee was to devise a regional physical and economic development strategy for the years 1992-2007 that would arrest the trend of emigration of its residents, attract newly arrived immigrants to the region, and at the same time protect natural resources and environmental quality. This paper is limited to discussion of the environmental aspects of the plan. It analyzes spatial concepts for distribution of projected population growth, evaluates environmental impacts of alternative plans, and proposes a decision-making framework and tools for minimizing natural resources loss from development at the local level. Assessment of potential environmental impacts generated quantitative data of natural resources areas. Application of the data in the plan evaluation stage showed that the alternative that concentrated most of the new development in central Galilee was the second-best choice environmentally, but was preferred as the best choice for overall qualities. The planning study offers an alternative environmental impact assessment (EIA) process to the one presently used in Israel by incorporating environmental considerations at the initial plan-making stage and not at the plan-approval stage. It demonstrated that in order to be effective, environmental assessment and land-use planning should be seen as one effort that is integrated from the start and in each stage of the plan-making process.KEY WORDS: Environmental assessment; Development planning; Galilee 相似文献

A Decision Support Framework for Science-Based, Multi-Stakeholder Deliberation: A Coral Reef Example 总被引:2,自引:0,他引:2

We present a decision support framework for science-based assessment and multi-stakeholder deliberation. The framework consists of two parts: a DPSIR (Drivers–Pressures–States–Impacts–Responses) analysis to identify the important causal relationships among anthropogenic environmental stressors, processes, and outcomes; and a Decision Landscape analysis to depict the legal, social, and institutional dimensions of environmental decisions. The Decision Landscape incorporates interactions among government agencies, regulated businesses, non-government organizations, and other stakeholders. It also identifies where scientific information regarding environmental processes is collected and transmitted to improve knowledge about elements of the DPSIR and to improve the scientific basis for decisions. Our application of the decision support framework to coral reef protection and restoration in the Florida Keys focusing on anthropogenic stressors, such as wastewater, proved to be successful and offered several insights. Using information from a management plan, it was possible to capture the current state of the science with a DPSIR analysis as well as important decision options, decision makers and applicable laws with a the Decision Landscape analysis. A structured elicitation of values and beliefs conducted at a coral reef management workshop held in Key West, Florida provided a diversity of opinion and also indicated a prioritization of several environmental stressors affecting coral reef health. The integrated DPSIR/Decision landscape framework for the Florida Keys developed based on the elicited opinion and the DPSIR analysis can be used to inform management decisions, to reveal the role that further scientific information and research might play to populate the framework, and to facilitate better-informed agreement among participants. 相似文献

Culture and the environment in Ghana 总被引:1,自引:0,他引:1
Hubert M. Dyasi 《Environmental management》1985,9(2):97-103
The traditional culture of Ghana stressed a strong relationship with the environment, and a culturally acceptable environmental management resulted from strictures and taboos related to the land. Following its independence in 1957, Ghana has enacted laws that reflect an enlightened environmental policy. These are especially important because of the difficulties Ghana has had in its economic development using Western technology that has damaged the fragile tropical ecosystem. A key aspect of Ghana's policy is the attempt to marry scientific knowledge and traditional beliefs for environmentally sound management of Ghana's resources. 相似文献

A new framework for environmental assessment is needed because no existing framework explicitly includes all types of environmental
assessments. We propose a framework that focuses on resolving environmental problems by integrating different types of assessments.
Four general types of assessments are included: (1) condition assessments to detect chemical, physical, and biological impairments;
(2) causal pathway assessments to determine causes and identify their sources; (3) predictive assessments to estimate environmental,
economic, and societal risks, and benefits associated with different possible management actions; and (4) outcome assessments
to evaluate the results of the decisions of an integrative assessment. The four types of assessments can be neatly arrayed
in a two-by-two matrix based on the direction of analysis of causal relationships (rows) and whether the assessment identifies
problems or solves them (columns). We suggest that all assessments have a common structure of planning, analysis, and synthesis,
thus simplifying terminology and facilitating communication between types of assessments and environmental programs. The linkage
between assessments is based on intermediate decisions that initiate another assessment or a final decision signaling the
resolution of the problem. The framework is applied to three cases: management of a biologically impaired river, remediation
of a contaminated site, and reregistration of a pesticide. We believe that this framework clarifies the relationships among
the various types of assessment processes and their links to specific decisions. 相似文献

DAVID P. LAWRENCE 《Environmental management》1997,21(1):23-42
/ Environmental impact assessment (EIA) has been identified as an important instrument for facilitating sustainability. However, to do so requires the integration of sustainability into EIA theory and practice. The sustainability concept is a valid and important environmental management perspective. However, many issues and obstacles need to be addressed further if the concept is to be translated into practical strategies. Sustainability can potentially infuse EIA with a clearer sense of direction, an ethical foundation, a mechanism for establishing priorities and assessing choices, and a means of linking EIA to other environmental management instruments. Conceptually, EIA and sustainability can be integrated, but frameworks should be refined, adpated to context, and linked to related initiatives. Sustainability should be explicitly incorporated into EIA legislation, guidelines, and institutional arrangements. An experimental approach to testing, assessing, and sharing experiences is suggested.A framework is first presented that defines and characterizes the sustainability concept. A further framework is then described for integrating sustainability into EIA at the conceptual level. The integration of sustainability and EIA at the regulatory level is next addressed through an overview of sustainability initiatives in EIA requirements in Canada. The Canadian examples include many promising initiatives but these and other experiences will need to be monitored, shared, and integrated into comprehensive environmental management strategies. Finally, means of incorporating sustainability into each activity in the EIA planning process are identified.KEY WORDS: Sustainability; Environmental impact assessment 相似文献

Soil erosion and non-point source pollution impacts assessment with the aid of multi-temporal remote sensing images 总被引:10,自引:0,他引:10
Soil erosion associated with non-point source pollution is viewed as a process of land degradation in many terrestrial environments. Careful monitoring and assessment of land use variations with different temporal and spatial scales would reveal a fluctuating interface, punctuated by changes in rainfall and runoff, movement of people, perturbation from environmental disasters, and shifts in agricultural activities and cropping patterns. The use of multi-temporal remote sensing images in support of environmental modeling analysis in a geographic information system (GIS) environment leading to identification of a variety of long-term interactions between land, resources, and the built environment has been a highly promising approach in recent years. This paper started with a series of supervised land use classifications, using SPOT satellite imagery as a means, in the Kao-Ping River Basin, South Taiwan. Then, it was designed to differentiate the variations of eight land use patterns in the past decade, including orchard, farmland, sugarcane field, forest, grassland, barren, community, and water body. Final accuracy was confirmed based on interpretation of available aerial photographs and global positioning system (GPS) measurements. Finally, a numerical simulation model (General Watershed Loading Function, GWLF) was used to relate soil erosion to non-point source pollution impacts in the coupled land and river water systems. Research findings indicate that while the decadal increase in orchards poses a significant threat to water quality, the continual decrease in forested land exhibits a potential impact on water quality management. Non-point source pollution, contributing to part of the downstream water quality deterioration of the Kao-Ping River system in the last decade, has resulted in an irreversible impact on land integrity from a long-term perspective. 相似文献

The European Union's Structural Funds are implemented by means of Regional Development Plans (RDP), whose regionally scoped environmental assessment is required. We highlight the deficiencies faced by this approach when subregional areas with high conservation natural values are involved and illustrate it with the case of the RDP of Andalusia region on Doñana National Park area (Spain). Commissioned by the World Wildlife Fund, a Strategic Environmental Assessment (SEA) of the Andalusian RDP was carried out focusing on Doñana and its area of influence. This is a complex space where some of the most environmentally valuable features in the continent coexist with a surrounding intense and multi-sector economic activity, threatening its conservation. In the absence of an established sustainability framework in the Region, a “trickle-down” SEA approach evidenced the need to produce a set of environmental, economic and social guidelines for sustainable management of land, against which the RDP objectives were tested for coherence. An “incremental” SEA approach was also tested, which involved the identification of 79 measures and actions stemming from the RDP provisions and other concurrent planning documents reviewed and the qualitative assessment of their individual and cumulative potential impacts on Doñana environments. In the light of the results, a set of complementary mitigating measures was proposed for inclusion in tiered stages of the planning process. Measures to avoid, reduce, remedy and monitor the major types of impact were proposed, including provisions for public participation. SEA emerges as an instrument for non-governmental organizations (NGOs) to carry out independent assessment of public development initiatives. 相似文献

Evaluation of Environmental Aspects Significance in ISO 14001 总被引:1,自引:0,他引:1
Põder T 《Environmental management》2006,37(5):732-743
The methodological framework set by standards ISO 14001 and ISO 14004 gives only general principles for environmental aspects
assessment, which is regarded as one of the most critical stages of implementing environmental management system. In Estonia,
about 100 organizations have been certified to the ISO 14001. Experience obtained from numerous companies has demonstrated
that limited transparency and reproducibility of the assessment process serves as a common shortcoming. Despite rather complicated
assessment schemes sometimes used, the evaluation procedures have been largely based on subjective judgments because of ill-defined
and inadequate assessment criteria. A comparison with some similar studies in other countries indicates a general nature of
observed inconsistencies. The diversity of approaches to the aspects’ assessment in concept literature and to the related
problems has been discussed. The general structure of basic assessment criteria, compatible with environmental impact assessment
and environmental risk analysis has also been outlined. Based on this general structure, the article presents a tiered approach
to help organize the assessment in a more consistent manner. 相似文献

Assessing ecological risk on a regional scale 总被引:17,自引:0,他引:17

Society needs a quantitative and systematic way to estimate and compare the impacts of environmental problems that affect
large geographic areas. This paper presents an approach for regional risk assessment that combines regional assessment methods
and landscape ecology theory with an existing framework for ecological risk assessment. Risk assessment evaluates the effects
of an environmental change on a valued natural resource and interprets the significance of those effects in light of the uncertainties
identified in each component of the assessment process. Unique and important issues for regional risk assessment are emphasized;
these include the definition of the disturbance scenario, the assessment boundary definition, and the spatial heterogeneity
of the landscape.
Although the research described in this article has been funded wholly or in part by the United States Environmental Protection
Agency (EPA) through Interagency Agreement Number DW89932112-01-2 to the U.S. Department of Energy, it has not been subjected
to EPA review and therefore does not necessarily reflect the views of EPA and no official endorsement should be inferred. 相似文献

A method is presented which combines environmental indices and estimates of inputs from various land uses to aid in environmental impact assessments. Unweighted pair/group cluster analyses are used to obtain relationships between easily observable environmental indices, such as vegetation types, soils, and geology, based on their mutual recurrence. These relationships are shown by using an ordination technique which shows the nature of complex impacts on a natural system. Results are used to develop anenvironmental effects sequence diagram based on known scientific and engineering principles and observed natural relationships. The diagram may be used in conjunction with land use data to estimate the possible magnitude of impacts on the pre-existing system which may result from such land use. Several examples are developed which quantify inputs from various land uses and which compare them with environmental inputs including point source and non-point source liquid and atmospheric emmissions, land modifications, and resource consumption. Known average values are used and a separate comparison is made in describing the vast differences between the project phases of construction versus longterm operation. A hypothetical environmental impact assessment is given for a small residential development in Chambers County, Texas, U.S. of A. 相似文献

Geographic information systems (GIS) technology is altering the work environment for planning and decision-making tasks. This
article is an account of a resource application that make use of the GIS technology. It provides some cost estimates and reasons
for the fairly slow development toward an integrated resource data base for environmental planning and management. It tries
to identify some of the constraints of such an integrated data-base approach toward environmental assessment. 相似文献

Environmental problem-solving and land-use management: A proposed structure for Australia 总被引:1,自引:0,他引:1
Arthur Conacher 《Environmental management》1980,4(5):391-405
A three-tiered structure of land-use and environmental management is here proposed for Australia. The structure is based on the idea that environment means the environment of people, and that environmental problems arise when a change in the interaction between people and their environment leads to conflicts about the use of land and resources. The heterogeneity of society means that a range of human aspirations and value systems must be satisfied by environmental managers. Existing methods of environmental management fail to achieve these objectives, due to inadequate perception of environmental problems by decision-makers, and the inability of currently available impact assessment techniques to resolve human conflicts associated with the use of land and resources. The main work of planning and managing land use and the environment would be carried out by regional authorities, supported by federal and state policy. Examples are given of moves towards regional administration in England and Wales, Western Australia, Australia and New Zealand. Community participation in the decision-making process is essential and can be achieved by electoral representation to the authoritative bodies and through procedures that ensure informed public comment on planning proposals. 相似文献

Humans have transformed much of Earth’s land surface, giving rise to loss of biodiversity, climate change, and a host of other environmental issues that are affecting human and biophysical systems in unexpected ways. To confront these problems, environmental managers must consider human and landscape systems in integrated ways. This means making use of data obtained from a broad range of methods (e.g., sensors, surveys), while taking into account new findings from the social and biophysical science literatures. New integrative methods (including data fusion, simulation modeling, and participatory approaches) have emerged in recent years to address these challenges, and to allow analysts to provide information that links qualitative and quantitative elements for policymakers. This paper brings attention to these emergent tools while providing an overview of the tools currently in use for analysis of human–landscape interactions. Analysts are now faced with a staggering array of approaches in the human–landscape literature—in an attempt to bring increased clarity to the field, we identify the relative strengths of each tool, and provide guidance to analysts on the areas to which each tool is best applied. We discuss four broad categories of tools: statistical methods (including survival analysis, multi-level modeling, and Bayesian approaches), GIS and spatial analysis methods, simulation approaches (including cellular automata, agent-based modeling, and participatory modeling), and mixed-method techniques (such as alternative futures modeling and integrated assessment). For each tool, we offer an example from the literature of its application in human–landscape research. Among these tools, participatory approaches are gaining prominence for analysts to make the broadest possible array of information available to researchers, environmental managers, and policymakers. Further development of new approaches of data fusion and integration across sites or disciplines pose an important challenge for future work in integrating human and landscape components. 相似文献

Public Participation Mechanisms in Environmental Disasters 总被引:1,自引:0,他引:1
This paper examines the role of public participation mechanisms in certain major environmental disasters. It examines situations in which people’s lifestyles or their lives have been directly threatened, and thus elicited citizen participation. Threatening issues often seem morally, physically, socially, economically, religiously, and otherwise unacceptable to a group. As will be presented in this paper, citizens voluntarily participate in a community activity when they see that their way of life has been threatened. An introductory historical perspective, the legal framework upon which it is based, and background information on the participatory mechanisms, all emphasizing the importance and need for empowering citizens with participatory skills so as to bring changes in the existing educational, legal, and social systems are presented. The major environmental accidents/disasters of Minamata, Japan; Bhopal, India; Seveso, Italy; Chernobyl, Ukraine; and Exxon-Valdez, Alaska are discussed, mainly to indicate the reaction, and the participatory mechanisms used by the affected communities in each of the sudden disasters that occurred. If citizens worldwide had been active participants in the environmental issues, it is quite possible that we would have experienced fewer environmental accidents. 相似文献

Over the last decade, New Zealand has implemented innovative reforms in respect of natural resource and environmental management. These include the Resource ManagementAct 1991 (RMA), a notable feature of which is the adoption of 'sustainable management' as the key principle guiding resource allocation and use. This and other features of the new administrative context for resource management strongly suggest a prominent role for geographicinformation systems (GIS) and related spatial information technology. In this paper we present an outline of the Regional Resource Evaluation Project (RREP), a project that has been established to explore and demonstrate the capabilities of GIS and related spatial information technology in the context of resource analysis and decision making. To date, the RREP has achieved important outcomes in terms of database design and development. An extensive information base which incorporates data on the physical and natural environment, patterns of human activity, and on social and demographic characteristics has been assembled. We describe the information systems, as well as some of the technical issues that attend to database design and development.We also provide brief reviews of two applications of the GIS to resource evaluation. One relates to the evaluation of changes in regional land use, with a focus on natural habitats. The other is concerned with land suitability assessment for plantation forestry. 相似文献

Land tenure plays a primary role in sustainable development efforts. However armed conflict and its repercussions reconfigure the network of social relations upon which all land tenure systems depend. In post‐conflict settings new laws have the opportunity to address tenure issues in the context of what people are already doing ‘on the ground’, with a view to moving from the fluidity of post‐conflict situations to a more solidified and peaceful social and legal environment. However there exists a lack of tools to analyze postwar land tenure and the prospects for reconstituting tenure systems to support recovery and development. This paper uses the Sustainable Livelihoods framework to examine postwar land tenure issues in order to draw out latent opportunities within emergent informal smallholder tenure constructs which may have utility in the reconstitution of national tenure systems. 相似文献

This paper proposes a method to select forest restoration priority areas consistently with the key principles of the Ecosystem
Approach (EA) and the Forest Landscape Restoration (FLR) framework. The methodology is based on the principles shared by the
two approaches: acting at ecosystem scale, involving stakeholders, and evaluating alternatives. It proposes the involvement
of social actors which have a stake in forest management through multicriteria analysis sessions aimed at identifying the
most suitable forest restoration intervention. The method was applied to a study area in the native forests of Northern Argentina
(the Yungas). Stakeholders were asked to identify alternative restoration actions, i.e. potential areas implementing FLR.
Ten alternative fincas—estates derived from the Spanish land tenure system—differing in relation to ownership, management,
land use, land tenure, and size were evaluated. Twenty criteria were selected and classified into four groups: biophysical,
social, economic and political. Finca Ledesma was the closest to the economic, social, environmental and political goals,
according to the values and views of the actors involved in the decision. This study represented the first attempt to apply
EA principles to forest restoration at landscape scale in the Yungas region. The benefits obtained by the application of the
method were twofold: on one hand, researchers and local actors were forced to conceive the Yungas as a complex net of rights
rather than as a sum of personal interests. On the other hand, the participatory multicriteria approach provided a structured
process for collective decision-making in an area where it has never been implemented. 相似文献
