Despite supportive policy frameworks and increased environmental awareness, a growing body of evidence indicates that environmental sustainability is not central to planning and decision-making processes in land reform in South Africa. Increasing pressures on government to meet land reform targets, cumbersome and often inappropriate environmental assessment procedures, and a confusing multitude of laws all contribute to neglect of long-term environmental sustainability considerations in land reform. This is exacerbated by poor recognition of resource rights, a lack of proactive and pre-emptive environmental management plans, and insufficient implementation capacity. This paper argues that the early incorporation of environmental sustainability issues in pre-settlement and post-settlement land reform planning processes could significantly improve the environmental, social and economic outcomes of these projects. A simple, participant-driven environmental sustainability assessment tool is proposed to achieve these environmental and developmental goals.  相似文献

Cumulative impact analysis is examined from a conceptual decision-making perspective, focusing on its implicit and explicit purposes as suggested within the policy and procedures for environmental impact analysis of the National Environmental Policy Act of 1969 (NEPA) and its implementing regulations. In this article it is also linked to different evaluation and decision-making conventions, contrasting a regulatory context with a comprehensive planning framework. The specific problems that make the application of cumulative impact analysis a virtually intractable evaluation requirement are discussed in connection with the federal regulation of wetlands uses. The relatively familiar US Army Corps of Engineers' (the Corps) permit program, in conjunction with the Environmental Protection Agency's (EPA) responsibilities in managing its share of the Section 404 regulatory program requirements, is used throughout as the realistic context for highlighting certain pragmatic evaluation aspects of cumulative impact assessment.To understand the purposes of cumulative impact analysis (CIA), a key distinction must be made between the implied comprehensive and multiobjective evaluation purposes of CIA, promoted through the principles and policies contained in NEPA, and the more commonly conducted and limited assessment of cumulative effects (ACE), which focuses largely on the ecological effects of human actions. Based on current evaluation practices within the Corps' and EPA's permit programs, it is shown that the commonly used screening approach to regulating wetlands uses is not compatible with the purposes of CIA, nor is the environmental impact statement (EIS) an appropriate vehicle for evaluating the variety of objectives and trade-offs needed as part of CIA. A heuristic model that incorporates the basic elements of CIA is developed, including the idea of trade-offs among social, economic, and environmental protection goals carried out within the context of environmental carrying capacity.  相似文献

ABSTRACT. The Nation has entered a new era of water quality management in which land use policy and regulation must assume an increasingly important role. The benefits of tertiary and advanced waste treatment may be offset by contradictory land use and pollution from land runoff. Unless land use planning and controls are included in water quality management, land-imposed constraints on water quality can be anticipated. Pollution from major types of land runoff are reviewed with respect to sources, effects, and control procedures. Emphasis is given to land use practices and controls. The crucial issue with regard to the latter is lack of land use policies at federal, state, and local levels. State legislation establishing guidelines and minimum standards for land use regulation by local government is required. The dependency of water quality on land use points to the fallacy of attempting to provide for comprehensive water pollution control outside the context of comprehensive land-water resource planning and management.  相似文献

Environmental justice sheds light on the distributive and procedural aspects of planning and decision-making. We examined the challenges arising from the perspective of environmental justice on multi-level and participatory environmental governance by exploring the governance of aquatic environments in the Helsinki Metropolitan Area. We found three main challenges and potential responses to them. First, even though most of Helsinki’s shoreline is free and/or accessible by road and accordingly used actively by people for recreational purposes, many parts of the shoreline are perceived as inaccessible, reflecting a need to combine factual and perceived accessibility of aquatic environments in detail during the planning processes and to discuss reasons for possible discrepancies between these two. Second, there was a remarkable seasonal variation in the use of aquatic environments, so more attention should be paid to social-demographic factors explaining the distribution of the use of urban nature. Third, it seems to be difficult to capture the variety of perceptions of people and to integrate them into planning and decision-making processes even on a local scale, and this challenge is likely even more pronounced on higher levels of planning and governance. Thus, better integration of regional and local-scale planning procedures should be encouraged. Building on these observations, we conclude that integration of procedural and distributive environmental justice into the practices of the governance of aquatic environments could remarkably decrease unwanted trade-offs and potential conflicts in their use and management.  相似文献

Recently, collaborative approaches to natural resource management have been widely promoted as ways to broaden participation and community involvement in furthering the goals of ecosystem management. The language of collaboration has even been incorporated into controversial legislation, such as the US Healthy Forests Restoration Act of 2003. This research examines collaboration and sharing management responsibility for federal public land with local communities through a case study of the Ashland Municipal Watershed in southern Oregon. A policy sciences approach is used to analyze community participation and institutional relationships between the US Department of Agriculture, Forest Service, and local city government in the planning processes of five land management actions occurring over a 7-year period. The knowledge gained from examining differing approaches to planning and decision making in the Ashland watershed is used to suggest future planning processes to develop and sustain the community capacity necessary to support implementation of community-based ecosystem management.  相似文献

Summary Australia's first National Environment Statement focuses on the substantial ecologic and economic impacts of land degradation, primarily in the significant agricultural mega-region of the Murray-Darling Basin. But the Statement only summarises existing policies to show a A$500 million spending programme on the environment. Inescapable, is the conclusion that economic growth as present and projected, and environmental sustainability, cannot co-exist in the long term. Levels of awareness of Australia's diverse environmental concerns were measured but no targets or future achievements were chartered — so how is effective management to be attained? The proposed significant and rapid devolution of power for action to local government, catchment management groups and community associations is a welcome development but this must be supported by adequate technical information and guidance by government.Dr Diana G. Day is an environmental policy analyst with major interests in water planning. She is currently setting up a new Centre for Environmental Management at Newcastle University, and is Director of the National Land and Water Resources Research and Development Corporation in Australia.  相似文献

The Land Condition Trend Analysis (LCTA) program is the US Army's standard for land inventory and monitoring, employing standardized methods of natural resources data collection, analyses, and reporting designed to meet multiple goals and objectives. Critical to using LCTA data in natural resources management decisions is the ability of the LCTA protocols to detect changes in natural resources. To quantify the ability of LCTA protocols to detect resource changes, power analysis techniques were used to estimate minimum detectable effect sizes (MDES) for selected primary and secondary management variables for three Army installations. MDES for a subset of primary variables were estimated using data from 27 installation LCTA programs. MDES for primary and secondary variables varied widely. However, LCTA programs implemented at larger installations with lower sampling intensities detected changes in installation resources as well as programs implemented at smaller more intensively sampled installations. As a national monitoring program that is implemented at individual installations, LCTA protocols provide relatively consistent monitoring data to detect changes in resources despite diverse resource characteristics and implementation constraints.  相似文献

/ The National Environmental Policy Act of 1969 (NEPA) was intended to promote a systematic, comprehensive, interdisciplinary approach to planning and decisionmaking, including the integration of the natural and social sciences and the design arts. NEPA critics have cited three key shortcomings in its implementation: (1) a lack of engagement with the NEPA process early in the planning process through interdisciplinary collaboration; (2) a lack of rigorous science and the incorporation of ecological principles and techniques; and (3) a lack of emphasis on the Act's substantive goals and objectives. In recent years and independent of NEPA, a policy of ecosystem management has been developed, which represents a fundamental change from a fragmented, incremental planning and management approach to a holistic, comprehensive, interdisciplinary land and resource management effort. We postulate that by incorporating ecosystem management principles in their planning and decisionmaking, federal agencies can address the shortcomings in NEPA implementation and move closer to NEPA's intent. A case analysis of EISs prepared by the USDA Forest Service before and after adopting an ecosystem management approach supports our hypothesis.  相似文献

The National Forest Management Act and National Environmental Policy Act require the use of an interdisciplinary team (ID team) to do integrated resource planning for the National Forests and the concurrent environmental analysis. A survey sent to all National Forest planning officers (82% response) reveals the composition of the ID teams used in integrated resource and land management planning. More than half the National Forests ID teams met NEPA and NFMA compositional requirements. National Forest planners recount their experiences with these ID teams. Despite frustrations with many aspects of the ID teams, the planners strongly support the idea that ID teams are an important part of the land-use planning process and think that their use leads to better National Forest integrated resource plans.  相似文献

The UK government has identified the land‐use planning system, and development plans in particular, as potentially powerful instruments for integrating national sustainability objectives into strategic decision making at local levels. One method for achieving this is through the use of so‐called ‘sustainability appraisals’, which are an extension of the established system of environmental appraisal used by planners since the early 1990s. A national framework is outlined in Planning Policy Guidance Note 12. Local authorities are now expected to conduct an environmental appraisal of their development plans which covers sustainable development issues. However, little research has been conducted on the effectiveness of current guidance in meeting this aim. By evaluating the implementation of sustainability appraisals nationally, this paper suggests that while government advice to appraise is generally being applied, the actual use of key sustainability principles in practice is rather variable. It then discusses these findings in relation to the changing context of appraisals in the UK and other national planning systems.  相似文献

Environmental sustainability goals are increasingly embedded in local planning, but implementation proves difficult. Using a survey of 217 planners working in a random sample of 146 small to mid-sized American cities and counties, we identify the organizational factors that support and hinder the implementation of environmentally sustainable practices. The analysis is based on a conceptual framework that encompasses organizational capacity, culture, structure, participatory decision-making, the framing of sustainability and contextual factors. We find that environmental sustainability implementation is lagging (although cities are generally ahead compared to counties) and that outcome evaluation is rare, precluding adaptive learning. The major barrier to implementation is that sustainability is low on political and managerial agendas. As expected, local public support, innovation-supportive organizational culture and the prioritization and framing of environmental sustainability support implementation. Surprisingly, innovation diffusion does not occur across neighbouring localities, local capacity and public participation are irrelevant for implementation and hierarchical rather than integrated institutional structures support implementation.  相似文献

U.S. Forest Service managers are required to incorporate social and biophysical science information in planning and environmental analysis. The use of science is mandated by the National Environmental Policy Act, the National Forest Management Act, and U.S. Forest Service planning rules. Despite the agency’s emphasis on ‘science-based’ decision-making, little is known about how science is actually used in recreation planning and management. This study investigated the perceptions of Forest Service interdisciplinary (ID) team leaders for 106 NEPA projects dealing with recreation and travel management between 2005 and 2008. Our survey data show how managers rate the importance of social and biophysical science compared to other potential ‘success factors’ in NEPA assessments. We also explore how team leaders value and use multi-disciplinary tools for recreation-related assessments. Results suggest that managers employ a variety of recreation planning tools in NEPA projects, but there appears to be no common understanding or approach for how or when these tools are incorporated. The Recreation Opportunity Spectrum (ROS) was the most frequently used planning tool, but the Visitor Experience and Resource Protection (VERP) framework was the most consistently valued tool by those who used it. We recommend further evaluation of the strengths and weaknesses of each planning tool and future development of procedures to select appropriate planning tools for use in recreation-related NEPA assessments.  相似文献

TIM: Assessing the sustainability of agricultural land management   总被引:1,自引:0,他引:1  
TIM (Threat Identification Model) is a framework for the ex ante assessment of agricultural land management sustainability at the land unit scale that identifies sources of unsustainability within agricultural land management systems. The model explicitly links defined hazards to land productivity and environmental integrity, land resource data and information, and land management practice options using expert and local knowledge on land management and its potential effects. The model was tested in the Crystal Creek Subcatchment, a narrow coastal strip of land situated in north Queensland, Australia. This area was chosen due to the expansion of the sugar industry onto increasingly marginal land in the area, which represents a threat to sustainable land use and a requirement for careful land-use planning and land management.TIM may be used in a relational database as a stand alone decision support system for land-management planning. Its usefulness in land-use planning is greatest when it is linked to a Geographic Information System (GIS) as shown in this paper. GIS allows TIM outputs, such as constraints to agriculture and site-specific best-management practices, to be identified in a spatially explicit manner.The main advantages of TIM are that it can be done ex ante, it removes the need to define sustainability assessment criteria and indicators, it utilises current understanding of the causes and effects of land degradation and how different land-management practices influence these, and links this knowledge to definite land-management options.  相似文献

Scenario analysis constitutes a valuable deployment method for scientific models to inform environmental decision-making, particularly for evaluating land degradation mitigation options, which are rarely based on formal analysis. In this paper we demonstrate such an assessment using the PESERA–DESMICE modeling framework with various scenarios for 13 global land degradation hotspots. Starting with an initial assessment representing land degradation and productivity under current conditions, options to combat instances of land degradation are explored by determining: (1) Which technologies are most biophysically appropriate and most financially viable in which locations; we term these the “technology scenarios”; (2) how policy instruments such as subsidies influence upfront investment requirements and financial viability and how they lead to reduced levels of land degradation; we term these the “policy scenarios”; and (3) how technology adoption affects development issues such as food production and livelihoods; we term these the “global scenarios”. Technology scenarios help choose the best technology for a given area in biophysical and financial terms, thereby outlining where policy support may be needed to promote adoption; policy scenarios assess whether a policy alternative leads to a greater extent of technology adoption; while global scenarios demonstrate how implementing technologies may serve wider sustainable development goals. Scenarios are applied to assess spatial variation within study sites as well as to compare across different sites. Our results show significant scope to combat land degradation and raise agricultural productivity at moderate cost. We conclude that scenario assessment can provide informative input to multi-level land management decision-making processes.  相似文献

An Environmental Management System (EMS) has been widely in use by many companies to manage the environmental effects of their operations. The process has recently gained ground in being adopted at city and municipal levels as well as in institutions such as universities. However, an EMS that is conducted at corporate level has some deficiencies when it is applied at city level. These deficiencies are in evaluating environmental goals and policies carried out to mainly ensure that the policies meet ISO 14001 standard and corporate requirements and neglect of public participation. Urban areas differ from companies due to their size, complexity and environmental challenges, high rate of growth and the dynamic nature of urban systems. Therefore, they need an urban environmental management approach that will assess the formulated urban environment policies and goals in a strategic method before implementation, including social dimensions such as public participation. Therefore, this paper proposes a modified approach to incorporate an EMS, called the Sustainable Urban Environmental Management Approach (SUEMA). The approach recognizes the above-mentioned deficiencies and benefits from the advantages of sustainability and Strategic Environmental Assessment (SEA) in the formulation and evaluation of policies, plans and programs. SUEMA is developed to ensure more sustainable urban environmental planning and development.  相似文献

The growing use of computers in environmental management is profoundly changing data collection procedures, analytic processes, and even the decision-making environment itself. The emerging technology of geographic information systems (GIS) is expanding this revolution to integrate spatial information fully into research, planning, and management of land. In one sense, this technology is similar to conventional map processing involving traditional maps and drafting aids, such as pens, rub-on shading, rulers, planimeters, dot grids, and acetate sheets for light-table overlays. In another sense, these systems provide advanced analytic capabilities, enabling managers to address complex issues in entirely new ways. This report discusses a fundamental approach to computer-assisted map analysis that treats entire maps as variables. The set of analytic procedures for processing mapped data forms a mathematical structure analogous to traditional statistics and algebra. All of the procedures discussed are available for personal computer environments.  相似文献

/ Environmental degradation in many hill forest regions of Asia, inhabited by indigenous/tribal communities is growing at an unprecedented rate. The case of Orissa State in eastern India is no exception. The government is of the view that the local population is responsible for forest degradation as they practice swidden cultivation and forest gathering indiscriminately to sustain their livelihoods. Based on economic merit alone, the government has undertaken some policy initiatives. Such initiatives that are meant to stop swidden cultivation have not been successful. This study recommends an integrated framework for developing a sustainable natural resource management practice for tribal communities. The framework has taken into consideration both economic and noneconomic factors in evaluating various alternatives. Furthermore, it has been applied to two tribal communities in Orissa (Juang and Saora). Based on an economic analysis comparing returns from swidden as well as wetland cultivation, it is observed that where forest degradation is not serious, wetland cultivation does not have a significant economic merit vis-à-vis swidden cultivation. However, in view of the long-term sustainability issue within ecological limits, swidden cultivation may be phased out in favor of wetland cultivation with an appropriate transition period. During this transition, government must adopt suitable policy initiatives to provide tribals tenurial rights to land, help financially in creating settled lands through terracing, introduce certain improved agroforestry techniques and train tribal people in other income-generating activities. Furthermore, all such interventions made by the government should have a strong sociocultural component in order to attract the tribal people to give up swidden cultivation.  相似文献

The US Army Land Condition-Trend Analysis (LCTA) program is a standardized method of data collection, analysis, and reporting designed to meet multiple goals and objectives. The method utilizes vascular plant inventories, permanent field plot data, and wildlife inventories. Vascular plant inventories are used for environmental documentation, training of personnel, species identification during LCTA implementation, and as a survey for state and federal endangered or threatened species. The permanent field plot data documents the vegetational, edaphic, topographic, and disturbance characteristics of the installation. Inventory plots are allocated in a stratified random fashion across the installation utilizing a geographic information system that integrates satellite imagery and soil survey information. Ground cover, canopy cover, woody plant density, slope length, slope gradient, soil information, and disturbance data are collected at each plot. Plot data are used to: (1) describe plant communities, (2) characterize wildlife and threatened and endangered species habitat, (3) document amount and kind of military and nonmilitary disturbance, (4) determine the impact of military training on vegetation and soil resources, (5) estimate soil erosion potential, (6) classify land as to the kind and amount of use it can support, (7) determine allowable use estimates for tracked vehicle training, (8) document concealment resources, (9) identify lands that require restoration and evaluate the effectiveness of restorative techniques, and (10) evaluate potential acquisition property. Wildlife inventories survey small and midsize mammals, birds, bats, amphibians, and reptiles. Data from these surveys can be used for environmental documentation, to identify state and federal endangered and threatened species, and to evaluate the impact of military activities on wildlife populations. Short- and long-term monitoring of permanent field plots is used to evaluate and adjust land management decisions.  相似文献

A budget allocation system for regional water quality management to achieve environmental sustainability was developed in this study to assist a local authority with making appropriate budget allocations for improving Regional Water Environmental Sustainability (RWES) in an efficient manner. The system consists of visions and goals, RWES indicators, and an analysis of budget allocation versus RWES. Visions and goals define task priorities for improving water environmental sustainability. Indicators are used to measure the progress of related tasks toward RWES goals. These indicators are classified by the Driving Force-State-Response (DSR) framework to facilitate the analysis of relationships among indicators. Linkages between budget allocation and indicators are also analyzed, and the result is used to assess whether the available budget is allocated properly to raise the RWES. The applicability of the system is demonstrated by a case study involving a local environmental protection authority.  相似文献

The advent of democracy in South Africa in 1994 has resulted in a radical law reform process, new systems of governance, and significantly transformed planning and decision-making processes. At the same time, principles of sustainability, integration, participation, social and environmental justice have also been placed squarely on the South African political agenda. Local government has become the intended focal point for addressing the socio-economic needs of local communities and sustainable service delivery, with the principal tool for achieving these developmental objectives the Integrated Development Plan (IDP). This paper examines the available policy frameworks, including those at the national level, guiding incorporation of environmental sustainability considerations into IDPs and highlights difficulties of achieving this in practice. Ideas for moving beyond rhetoric to practical mainstreaming of environmental sustainability considerations in IDPs are provided.  相似文献
