There has been increasing recognition within systematic conservation planning of the need to include social data alongside
biophysical assessments. However, in the approaches to identify potential conservation sites, there remains much room for
improvement in the treatment of social data. In particular, few rigorous methods to account for the diversity of less-easily
quantifiable social attributes that influence the implementation success of conservation sites (such as willingness to conserve)
have been developed. We use a case-study analysis of private conservation areas within the Little Karoo, South Africa, as
a practical example of the importance of incorporating social data into the process of selecting potential conservation sites
to improve their implementation likelihood. We draw on extensive data on the social attributes of our case study obtained
from a combination of survey questionnaires and semi-structured interviews. We discuss the need to determine the social attributes
that are important for achieving the chosen implementation strategy by offering four tested examples of important social attributes
in the Little Karoo: the willingness of landowners to take part in a stewardship arrangement, their willingness to conserve,
their capacity to conserve, and the social capital among private conservation area owners. We then discuss the process of
using an implementation likelihood ratio (derived from a combined measure of the social attributes) to assist the choice of
potential conservation sites. We conclude by summarizing our discussion into a simple conceptual framework for identifying
biophysically-valuable sites which possess a high likelihood that the desired implementation strategy will be realized on
them. 相似文献

Effective and efficient water resources management to meet the increasing demands for food, energy, and domestic and industrial water is an imperative for Asian countries. As a basis for analyzing Asian water resources management problems, a three-element conceptual framework is presented: (1) water resources management as a system, composed of a set of facilities, operating rules, and incentives applied to water resources through an institutional arrangement; (2) water resources management as a process involving several stages beginning with planning and continuing with design, construction, operation and maintenance; and (3) water resources management as a set of linked activities and tasks required to produce the desired outputs. Using this framework to assess performance it is possible to analyze the linkages among water resources problems, water resources management, and water resources organizations and administrative arrangements. Examples are presented of such linkages as applied to problems of erosion and sedimentation, flooding, salinity, water demand-supply imbalances, and water pollution. Brief analytical summaries of eight critical water resources management problems in Asia are presented, along with an illustration of the complexity of water resources organization and administration, using Thailand as the example. 相似文献

A Multiscale Conceptual Framework for Integrated Ecogeomorphological Research to Support Stream Naturalization in the Agricultural Midwest 总被引:1,自引:0,他引:1
The complexity of fluvial systems necessitates interdisciplinary research in fluvial geomorphology and aquatic ecology to
develop a fundamental understanding of interconnections among biotic and abiotic aspects of these systems. Integrated knowledge
of this type is vital for environmental management of streams in human-dominated environments. A conceptual framework is presented
for integrating geomorphological and ecological research on streams in East Central Illinois, USA, a glaciated low-relief
agricultural landscape. The framework embodies a multiscale perspective in which a geomorphological conception of the fluvial
system is used to define a hierarchy of characteristic spatial scales for exploring important linkages between stream geomorphology
and aquatic ecology. The focus ecologically is on fish, because a rich body of historical information exists on fisheries
in East Central Illinois and because past work has suggested that availability of physical habitat is a major factor influencing
the community characteristics of fish in this human-altered environment. The hierarchy embodied in the framework includes
the network, link, planform, bar unit, bar element, and bedform/grain scales. Background knowledge from past research is drawn
upon to identify potential linkages between geomorphological and ecological conditions at each of these scales.
The conceptual framework is useful for guiding integrated ecogeomorphological research at specific scales and across different
scales. It also is helpful for illustrating how widespread human modification of streams has catastrophically altered the
scalar structure of fluvial systems in East Central Illinois. Knowledge emerging from the integrated research provides a basis
for environmental-management schemes directed toward stream naturalization. 相似文献

Community-based collaborative groups involved in public natural resource management are assuming greater roles in planning,
project implementation, and monitoring. This entails the capacity of collaborative groups to develop and sustain new organizational
structures, processes, and strategies, yet there is a lack of understanding what constitutes collaborative capacity. In this
paper, we present a framework for assessing collaborative capacities associated with community-based public forest management
in the US. The framework is inductively derived from case study research and observations of 30 federal forest-related collaborative
efforts. Categories were cross-referenced with literature on collaboration across a variety of contexts. The framework focuses
on six arenas of collaborative action: (1) organizing, (2) learning, (3) deciding, (4) acting, (5) evaluating, and (6) legitimizing.
Within each arena are capacities expressed through three levels of social agency: individuals, the collaborative group itself,
and participating or external organizations. The framework provides a language and set of organizing principles for understanding
and assessing collaborative capacity in the context of community-based public forest management. The framework allows groups
to assess what capacities they already have and what more is needed. It also provides a way for organizations supporting collaboratives
to target investments in building and sustaining their collaborative capacities. The framework can be used by researchers
as a set of independent variables against which to measure collaborative outcomes across a large population of collaborative
efforts. 相似文献

A Conceptual Model for Defining and Assessing Land Management Units Using a Fuzzy Modeling Approach in GIS Environment 总被引:5,自引:0,他引:5
Appropriate land management decisions are important for current and future use of the land to ensure its sustainability. This
requires that land management units (LMUs) be specified to enable the identification of specific parameters employed in decision
making processes. This paper presents the development of a conceptual model, within geographic information systems (GIS),
for defining and assessing LMUs from available biophysical information. The model consists of two main components (sub-models):
land quality-based suitability analysis and soil erosion estimation. Using a fuzzy set methodology, the first sub-model was
constructed to derive a land suitability index (LSI) for a cropping land utilization type. The LSI thus highlights the suitability
grades of every pixel in the study area on a continuous basis. A sub-model of soil erosion was established based on the Revised
Universal Soil Loss Equation (RUSLE) utilising the same spatial data bases employed for structuring the LSI. Using a soil
loss tolerance principle, a fuzzy membership function of average annual soil loss (called soil loss index, SLI) was established,
leading to compatibility between LSI and SLI for data integration. LMUs were then derived from various combinations of LSI
and SLI. The methodology developed shows the significance of the model for refining available land suitability evaluation
systems, which take no account of expected land degradation (from erosion) due to a nominated land use. It also provides a
valuable guideline for cost-effective GIS applications in the identification and assessment of homogeneous land units, using
available spatial information sets, at a finer scale. 相似文献

/ In this paper we develop a conceptual framework for selectingstressor data and analyzing their relationship to geographic patterns ofspecies richness at large spatial scales. Aspects of climate and topography,which are not stressors per se, have been most strongly linked withgeographic patterns of species richness at large spatial scales (e.g.,continental to global scales). The adverse impact of stressors (e.g., habitatloss, pollution) on species has been demonstrated primarily on much smallerspatial scales. To date, there has been a lack of conceptual developmenton how to use stressor data to study geographic patterns of speciesrichness at large spatial scales.The framework we developed includes four components: (1) clarification of theterms stress and stressor and categorization of factors affecting speciesrichness into three groups-anthropogenic stressors, natural stressors, andnatural covariates; (2) synthesis of the existing hypotheses for explaininggeographic patterns of species richness to identify the scales over whichstressors and natural covariates influence species richness and to providesupporting evidence for these relationships through review of previousstudies; (3) identification of three criteria for selection of stressor andcovariate data sets: (a) inclusion of data sets from each of the threecategories identified in item 1, (b) inclusion of data sets representingdifferent aspects of each category, and (c) to the extent possible, analysisof data quality; and (4) identification of two approaches for examiningscale-dependent relationships among stressors, covariates, and patterns ofspecies richness-scaling-up and regression-tree analyses.Based on this framework, we propose 10 data sets as a minimum data base forexamining the effects of stressors and covariates on species richness atlarge spatial scales. These data sets include land cover, roads, wetlands(numbers and loss), exotic species, livestock grazing, surface water pH,pesticide application, climate (and weather), topography, and streams.KEY WORDS: Anthropogenic impacts; Biodiversity; Environmental gradients;Geographic information systems; Hierarchy 相似文献

Corporate social responsibility (CSR) has long been an issue for research and practice. More recently, in response to growing public scrutiny, it has also gained importance in the agribusiness sector. Research has highlighted a growing gap between public perceptions of farming and food production processes and the realities of modern agriculture and the food industry. This can threaten the reputation and legitimacy of companies operating in this sector. One proactive means for companies to meet societal expectations is to make an active commitment to society and its needs by implementing a CSR policy. However, there is still no clear definition of CSR, and what important stakeholders actually expect from companies remains largely unknown. This paper focuses on consumers’ perception of CSR. Its objective is to explore a CSR policy design for German agribusiness based on Archie B. Carroll’s famous pyramid model. A consumer survey was conducted to evaluate the CSR demands society places on agribusiness companies. An explorative factor analysis was employed to discover the outline of the construct in the German agribusiness context. The results reveal that Carroll’s model, which was developed from a U.S. point of view, cannot be confirmed for German agribusiness. Instead of Carroll’s four responsibility groups, three areas of responsibility were identified: economic, internal and external. These results have manifold implications for CSR strategies in agribusiness firms and represent an important origin for future investigations on CSR in other countries as well as in specific agribusiness subsectors. 相似文献

A GIS/Simulation Framework for Assessing Change in Water Yield over Large Spatial Scales 总被引:1,自引:0,他引:1
Recent legislation to initiate vegetation management in the Central Sierra hydrologic region of California includes a focus
on corresponding changes in water yield. This served as the impetus for developing a combined geographic information system
(GIS) and simulation assessment framework. Using the existing vegetation density condition, together with proposed rules for
thinning to reduce fire risk, a set of simulation model inputs were generated for examining the impact of the thinning scenario
on water yield. The approach allows results to be expressed as the mean and standard deviation of change in water yield for
each 1-km2 map cell that is thinned. Values for groups of cells are aggregated for typical watershed units using area-weighted averaging.
Wet, dry, and average precipitation years were simulated over a large region. Where snow plays an important role in hydrologic
processes, the simulated change in water yield was less than 0.5% of expected annual runoff for a typical watershed. Such
small changes would be undetectable in the field using conventional stream flow analysis. These results suggest that use of
water yield increases to help justify forest-thinning activities or offset their cost will be difficult. 相似文献

Companies react in different ways to environmental regulation. A prevailing view in the literature suggests that external factors, particularly stakeholder groups, exert the most influence on the environmental responses of firms. This paper reports on research that examines the influence of a range of possible determinants, both internal and external, on the way Australian mining companies respond to environmental approvals regulation. External pressures included stakeholder pressure, jurisdictional culture and market characteristics, and internal pressures included organizational culture, organizational learning, the influence of individuals within firms and company size. The study found that the internal pressures of organizational culture, organiza tional learning and the influence of individuals exert the greatest influence on mining company response to environmental approvals regulation. These results suggest that existing explanations of corporate environmental behaviour, which emphasize external factors, should be complemented by a focus on the internal dynamics of firms. 相似文献

The frequency and severity of mass coral bleaching events are predicted to increase as sea temperatures continue to warm under
a global regime of rising ocean temperatures. Bleaching events can be disastrous for coral reef ecosystems and, given the
number of other stressors to reefs that result from human activities, there is widespread concern about their future. This
article provides a strategic framework from the Great Barrier Reef to prepare for and respond to mass bleaching events. The
framework presented has two main inter-related components: an early warning system and assessment and monitoring. Both include
the need to proactively and consistently communicate information on environmental conditions and the level of bleaching severity
to senior decision-makers, stakeholders, and the public. Managers, being the most timely and credible source of information
on bleaching events, can facilitate the implementation of strategies that can give reefs the best chance to recover from bleaching
and to withstand future disturbances. The proposed framework is readily transferable to other coral reef regions, and can
easily be adapted by managers to local financial, technical, and human resources. 相似文献

As collaborative groups gain popularity as an alternative means for addressing conflict over management of public lands, the
need for methods to evaluate their effectiveness in achieving ecological and social goals increases. However, frameworks that
examine both effectiveness of the collaborative process and its outcomes are poorly developed or altogether lacking. This
paper presents and evaluates the utility of the holistic ecosystem health indicator (HEHI), a framework that integrates multiple
ecological and socioeconomic criteria to evaluate management effectiveness of collaborative processes. Through the development
and application of the HEHI to a collaborative in northern Arizona, the Diablo Trust, we present the opportunities and challenges
in using this framework to evaluate the ecological and social outcomes of collaborative adaptive management. Baseline results
from the first application of the HEHI are presented as an illustration of its potential as a co-adaptive management tool.
We discuss lessons learned from the process of selecting indicators and potential issues to their long-term implementation.
Finally, we provide recommendations for applying this framework to monitoring and adaptive management in the context of collaborative
management. 相似文献

Over the last two decades, mining and mineral exploration companies have adopted various environmental management practices in response to society’s pressure for better environmental protection. The literature highlights a number of benefits and challenges for companies adopting environmental management practices with the Greek Mining and Mineral Industry (GMMI) facing similar issues. In order to analyze the challenges faced by the GMMI, a Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis was conducted, which examined the strengths, weaknesses, opportunities and threats faced by the industry when adopting environmental management practices. The analysis prescribes policy recommendations both for the government and industry which, if adopted, could facilitate improved environmental performance. 相似文献

Industry Response to the Challenge of Sustainability: The Case of the Canadian Nonferrous Mining Sector 总被引:3,自引:0,他引:3
Luis E. Sánchez 《Environmental management》1998,22(4):521-531
/ The paper investigates how the Canadian nonferrous sector is tackling the challenge of sustainable development. Although there is no consensus as to what sustainable development means in practice for management in the sector, at least three dimensions must be taken into account: (1) metals are recyclable, the availability of this resource is not a concern for the foreseeable future; (2) the need to minimize environmental impacts of metals exploration, extraction, transformation, consumption, and recycling; and (3) production activities should not be socially or culturally disruptive. The nonferrous mining industry faces several environmental problems. Some of the most significant are acid mine drainage, sulfur emissions, recycling, and metals toxicity. The industry has developed a number of responses to address these specific concerns as well as other more general challenges. Six strategies are described and analyzed: (1) research and development, (2) an effort of consensus building among stakeholders known as the Whitehorse Mining Initiative, (3) international networking, (4) active involvement in the development of environmental management standards, (5) management reorganization and (6) voluntary agreements. The importance of external factors in the shaping of corporate environmental management practices is discussed, in particular the role of government. Progress has been achieved in three areas: (1) managerial practices and organization, (2) reducing the impacts of ongoing operations and (3) minimizing future liabilities, but two significant fields of conflict remain, namely mining in wilderness areas and projects on aboriginal lands.KEY WORDS: Canada; Environmental management; Minerals industry; Nonferrous metals; Sustainable development; Whitehorse Mining Initiative 相似文献

Development and Climate Change: A Mainstreaming Approach for Assessing Economic,Social, and Environmental Impacts of Adaptation Measures 总被引:1,自引:1,他引:1
The paper introduces the so-called climate change mainstreaming approach, where vulnerability and adaptation measures are
assessed in the context of general development policy objectives. The approach is based on the application of a limited set
of indicators. These indicators are selected as representatives of focal development policy objectives, and a stepwise approach
for addressing climate change impacts, development linkages, and the economic, social and environmental dimensions related
to vulnerability and adaptation are introduced. Within this context it is illustrated using three case studies how development
policy indicators in practice can be used to assess climate change impacts and adaptation measures based on three case studies,
namely a road project in flood prone areas of Mozambique, rainwater harvesting in the agricultural sector in Tanzania and
malaria protection in Tanzania. The conclusions of the paper confirm that climate risks can be reduced at relatively low costs,
but the uncertainty is still remaining about some of the wider development impacts of implementing climate change adaptation
measures. 相似文献

Increasingly government agencies are seeking to quantify the outcomes of proposed policy options in terms of ecosystem service
benefits, yet conflicting definitions and ad hoc approaches to measuring ecosystem services have created confusion regarding
how to rigorously link ecological change to changes in human well-being. Here, we describe a step-by-step framework for producing
ecological models and metrics that can effectively serve an economic-benefits assessment of a proposed change in policy or
management. A focus of the framework is developing comparable units of ecosystem goods and services to support decision-making,
even if outcomes cannot be monetized. Because the challenges to translating ecological changes to outcomes appropriate for
economic analyses are many, we discuss examples that demonstrate practical methods and approaches to overcoming data limitations.
The numerous difficult decisions that government agencies must make to fairly use and allocate natural resources provides
ample opportunity for interdisciplinary teams of natural and social scientists to improve methods for quantifying changes
in ecosystem services and their effects on human well-being. This framework is offered with the intent of promoting the success
of such teams as they support managers in evaluating the equivalency of ecosystem service offsets and trades, establishing
restoration and preservation priorities, and more generally, in developing environmental policy that effectively balances
multiple perspectives. 相似文献
