A multicriteria model for planning agricultural regions within a context of groundwater rational management

Current international research focuses on topics like sustainable development, regional planning, environmental decision making and implementation, biodiversity conservation plus a number of other relevant issues, especially at times of economic crisis as today. Economic growth and environmental protection can go hand in hand, provided that decision makers develop and use tools and insights targeting in the implementation of successful and robust long term policies. This paper was developed in the framework of a European research project and implements a Multicriteria Mathematical Programming model that optimises the sustainable management of agricultural regions taking in account the available resources (land, labour, capital) and environmental parameters (agrochemicals, water consumption). The model achieves the optimum farm plan in the area combining different criteria to a utility function under a set of constraints and the spatial integration of the vulnerability maps of the regions into the model enables the regional authorities to design policies for the optimal agricultural development and the groundwater protection from the agricultural land uses. Furthermore, the model is used to simulate different scenarios and policies by the local stakeholders, due to changes on different social, economic and environmental parameters. In this way the decision makers can achieve alternative farm plans and agricultural land uses as well as to estimate economic, social and environmental impacts of different policies. The model has been applied to an agricultural region in Northern Greece and proved to be a valuable tool in the implementation of environmental policies and actions, especially in agricultural regions in a delicate balance as the study area.     

Sharing environmental space: the role of law,economics and politics

The concept of ‘environmental space’ has been put forward as a means for providing specific meaning to sustainability. The concept combines the idea of the existence of environmental limits with a strong principle of environmental justice. It has been used as a basis for the development of sustainable action plans for many European countries, and has attracted political interest. However, thus far, the concept has found limited application by governments. The paper identifies and discusses several issues that need to be addressed for the environmental space approach to be implemented. Three main options for the institutionalization of the approach are discussed: within the legal‐constitutional framework (as rights and obligations), within the economic system (as environmental property rights), and through green planning (as specific objectives and targets contained in national environmental plans or strategies). The paper discusses the ability of the three options to deal with the issues identified, assessing their relative advantages and disadvantages, and to what extent these options are complementary. Finally, conclusions are drawn about the viability of the concept of ‘environmental space’.     

Integrating biodiversity conservation and addressing economic needs: An experience with Nepal's community forestry

The forests of Nepal, which in the past were at least nominally under the direct control of the state, are today increasingly entrusted to local people in the name of community forestry (CF). CF is considered a successful endeavour in managing forest resources, conserving biodiversity and supplying people with basic economic needs. In order to assess to what extent the two goals of biodiversity conservation and meeting economic needs of people have been integrated through CF, four community forestry user groups (CFUGs) were studied in the Mid-hills ecological zone. Based on a participatory survey and a critical review of the statutes and operational plans of these CFUGs, it was found that integration of biodiversity conservation was still insufficient, and that improvements in the policy and management regimes of CF are necessary to achieve a balance between biodiversity conservation and economic use of the forest resources.     

Land Use Development Planning and the Notion of Sustainable Development: Exploring Constraint and Facilitation within the English Planning System

This paper explores the English land use planning system's actual and potential abilities to both facilitate and constrain the advancement of sustainable development through the preparation of statutory development plans. The exploration is empirically based, focusing upon the conceptual and procedural issues most pertinent to the incorporation of sustainable development within this sector of public policy making. The findings reveal a lack of unified coherence in approach amongst local planning authorities as they struggle to translate the rhetoric of sustainable development into practice. One can detect, however, areas of difficulty and potential opportunity surfacing in the plan preparation process relating to issues of public participation, Local Agenda 21, environmental appraisal, data gathering, resources and guidance. There is also an indication that the institutional framework for incorporation lacks the facility to adopt a consistent position with regard to what one can consider as sustainability-orientated application principles.     

Using Ecological Footprints as a Policy Driver: The Case of Sustainable Construction Planning Policy in London

Abstract

The forests of Nepal, which in the past were at least nominally under the direct control of the state, are today increasingly entrusted to local people in the name of community forestry (CF). CF is considered a successful endeavour in managing forest resources, conserving biodiversity and supplying people with basic economic needs. In order to assess to what extent the two goals of biodiversity conservation and meeting economic needs of people have been integrated through CF, four community forestry user groups (CFUGs) were studied in the Mid-hills ecological zone. Based on a participatory survey and a critical review of the statutes and operational plans of these CFUGs, it was found that integration of biodiversity conservation was still insufficient, and that improvements in the policy and management regimes of CF are necessary to achieve a balance between biodiversity conservation and economic use of the forest resources.     

Integration of Environmental Assessment into the Regional Development Planning Process of the Galilee

/ 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     

Examining strategic sustainability plans and smart-growth land-use measures in California cities

Given many potential obstacles, what types of strategic plans and measures for climate protection and/or energy sustainability are more likely than others to be adopted by cities? What are the key internal and external obstacles to adopting and implementing these plans and measures? Based on data obtained from a survey conducted from 2010 to 2011 and other sources, this paper develops a framework derived from political contracting theory and strategic orientation literature to examine how public management obstacles, socio-economic factors, and political factors influence a city's likelihood of having strategic energy sustainability plans and measures in place. Moreover, this paper finds that many California cities remain reluctant to require residents and businesses to comply with more challenging sustainability measures, such as smart-growth land-use practices, and that those cities with a strategic energy sustainability plan already in place tend to be more willing to adopt smart-growth land-use measures.     

Forest products and traditional peoples: Economic, biological, and cultural considerations

Conservationists and environmental economists have promoted the extraction of non–timber forest products (NTFP) as an alternative to forest conversion and as a means to benefit forest peoples. This article discusses the development of NTFP economic analyses and some economic, biological and socio–cultural constraints on the use of forest resources and methodological limitations of NTFP investigations. Several case studies document the importance of the forest in both North and South America. While studies differ in their conclusions regarding the sustainability of NTFP extraction, most researchers agree that sustainable harvesting is rare. The article argues for additional considerations that transcend the biological and economic concerns. While forests provide the basis of material culture for peoples that inhabit them, they are also linked intrinsically to the religion, mythology, and psyche of native peoples. Conservationists have an ethical obligation to consider the needs and desires of these people in conjunction with conservation and management plans.     

WATER AND THE ENERGY CRISIS1

ABSTRACT: Water and energy are inextricably bound. Energy is consumed and sometimes produced by every form of water resources system. Opportunities for future development and production of energy resources abound as well as those for significant reductions in energy consumption through wise water development and management. Technological, political, social, economic and environmental factors interrelate in the energy-water mix. The role of the water resources planner will have to be expanded to include assessment of water-energy impacts in addition to traditional planning considerations. An energy conservation account may well have to be added to the dimensions of national economic development and environmental quality in water resources planning. Ways must be found to reduce amounts and rates of water used and energy consumed through new manufacturing processes, improved irrigation practices, better management, new or altered social-political-economic arrangements and other procedures. To do this will require setting priorities and making difficult management decisions. The water fraternity can play a major role in alleviating the energy crisis we now face.     

GROUNDWATER MANAGEMENT1

There are four groundwater resources to be managed: yield, storage capacity, water-in-storage, and transmissivity. Management concepts have changed over the years, with today's concept which covers comprehensive integrated use of the four groundwater resources with surface water resources to provide the most efficient water service for an area in terms of quantity, quality, and cost. Complete geologic and hydrologic understanding provides a base for formulation of plans which can utilize the techniques of artificial recharge, control of sea water intrusion, and variation of pumping patterns while protecting the resources through proper well construction and abandonment, placement of sanitary landfills, and liquid waste disposal. Plan formulation involves varying recharge and extraction amounts while maintaining the total of pumped groundwater and developed surface water equal to the projected and future demand. Physical limitations of the system must be recognized to assure reality of the plans. Legal constraints should not be placed on the plan formulation process. A present worth or other technique is used to provide an economic comparison among plans. Implementation will entail development of legal and organizational structure, with the most difficult problems relating to the management organization in terms of boundaries and powers.     

Preliminary Strategic Environmental Assessment of the Great Western Development Strategy: Safeguarding Ecological Security for a New Western China

The Great Western Development Strategy (GWDS) is a long term national campaign aimed at boosting development of the western area of China and narrowing the economic gap between the western and the eastern parts of China. The Strategic Environmental Assessment (SEA) procedure was employed to assess the environmental challenges brought about by the western development plans. These plans include five key developmental domains (KDDs): water resource exploitation and use, land utilization, energy generation, tourism development, and ecological restoration and conservation. A combination of methods involving matrix assessment, incorporation of expert judgment and trend analysis was employed to analyze and predict the environmental impacts upon eight selected environmental indicators: water resource availability, soil erosion, soil salinization, forest destruction, land desertification, biological diversity, water quality and air quality. Based on the overall results of the assessment, countermeasures for environmental challenges that emerged were raised as key recommendations to ensure ecological security during the implementation of the GWDS. This paper is intended to introduce a consensus-based process for evaluating the complex, long term pressures on the ecological security of large areas, such as western China, that focuses on the use of combined methods applied at the strategic level.

Conservation of building materials and the future of the built environment

Building uses a combination of materials resources ranging from clay to bronze. Some of these resources are widely available, but require substantial energy resources to process and distribute them as the volumes used are so great. Other resources, like copper, are in much smaller supply. The resources used in building need to be examined against the future resource limitations in their supply and the possibilities of recycling. The links between building and waste cycles will also be critical, as wastes from other processes can often be incorporated into the building process. Design for recycling has to be balanced against the advantages of design for longer life. Reversible cementitious processes could confer enormous advantages if the reversibility was safely controllable, but this represents a very formidable scientific problem. The advantages of composite materials need to be balanced against the difficulties of effective recycling, for example reinforced concrete. The building as an energy conservation device also needs more emphasis. The final section deals with the concept of the materials conservation city in a Utopian way. It is designed to stimulate constructive thinking about resource conservation and materials recycling.     

Integrated water resources planning

A water resources plan should consider the missions of various governmental units and the interests of those affected beneficially or adversely by the plan. Its development should involve many professional disciplines and should take account of institutional, economic, environmental, social and other effects. For developing countries, water resources development and management should contribute as much as possible to the amelioration of the basic problems of the human condition, while avoiding serious damage to ecological populations and environmental quality. This paper outlines what has and has not worked in the planning of water resources, based on published literature and the unpublished views of United Nations and World Bank staff, and discusses the characteristics of effective integrated water resources planning.     

An analytical framework for strategic delta planning: negotiating consent for long-term sustainable delta development

Sectoral planning on water, agriculture and urban development has not been able to prevent increased flood risks and environmental degradation in many deltas. Governments conceive strategic delta planning as a promising planning approach and develop strategic delta plans. Such plans are linked to actions and means for implementation in the short-term, in line with long-term strategic choices. This paper introduces an analytical framework that focuses on the role of actors, innovative solutions and participatory planning tools in negotiating consent for the strategic choices in a delta plan and its implementation. Cases of Bangladesh, the Netherlands and Vietnam are discussed as a plausibility probe to explore the framework's potential. The probe reveals that the framework is promising to explain the process and outcomes of strategic delta planning in urbanizing deltas. The paper ends with an initial research agenda to stimulate research and discussion on this new delta planning approach.     

城市环境总体规划中的布局问题研究——以北京市丰台区为例

城市环境总体规划是对城市中长期环境管理的综合安排,是环境保护基础性的规划,其核心问题在于规模、结构和布局,即从城市环境、资源与生态约束角度为社会经济发展规划、城市总体规划与土地利用规划提出限制(环境、资源与生态红线),从环境承载力与发展生态适宜性分区角度为城市发展规划提出发展适度规模、结构与布局。在城市"多规融合"的实践过程中,城市环境总体规划,作为政府综合决策的重要支撑之一,可以为其他的规划编制提供约束条件以及土地供给能力测算值,使得各规划间能够相互支撑、相互融合,因此有必要先行。本文以北京市丰台区环境总体规划为例,从布局角度出发,基于区域土地资源供给能力对丰台区进行土地生态适宜性评价,并得到土地生态适宜性区划图,从而提出丰台区城市总体规划与土地利用规划的限制条件,为城市环境总体规划先行提供科学依据。     

What drives plan implementation? Plans,planning agencies and developers

This article investigates the determinants of plan implementation by applying a recently‐developed Plan Implementation Evaluation methodology. The lack of methodology to assess the implementation of plans has so far precluded any systematic analysis of the determinants of the implementation of local environmental plans. The article focuses on the implementation of plans in New Zealand. The key factors of implementation are: the quality of the plan; the capacity and commitment of land developers to implement plans; the capacity and commitment of the staff and leadership of planning agencies to implement plans; and the interactions between developers and the agency. The analysis is based on 353 permits implementing six local environmental plans in New Zealand, and on surveys of the developers who obtained the permits and of the planning agencies that granted the permits. The analysis finds that plan implementation is mainly driven by the resources of the planning agencies and by the quality of the plans, rather than by the characteristics of developers. Investments in plan writing and agency and staff capacity building thus improve the implementation of plans in the long‐run.     

Fair fund distribution for a municipal incinerator using GIS-based fuzzy analytic hierarchy process

Burning municipal solid waste (MSW) can generate energy and reduce the waste volume, which delivers benefits to society through resources conservation. But current practices by society are not sustainable because the associated environmental impacts of waste incineration on urbanized regions have been a long-standing concern in local communities. Public reluctance with regard to accepting the incinerators as typical utilities often results in an intensive debate concerning how much welfare is lost for those residents living in the vicinity of those incinerators. As the measure of welfare change with respect to environmental quality constraints nearby these incinerators remains critical, new arguments related to how to allocate the fair fund among affected communities became a focal point in environmental management. Given the fact that most County fair fund rules allow a great deal of flexibility for redistribution, little is known about what type of methodology may be a good fit to determine the distribution of such a fair fund under uncertainty. This paper purports to demonstrate a system-based approach that helps any fair fund distribution, which is made with respect to residents' possible claim for fair damages due to the installation of a new incinerator. Holding a case study using integrated geographic information system (GIS) and fuzzy analytic hierarchy process (FAHP) for finding out the most appropriate distribution strategy between two neighboring towns in Taipei County, Taiwan demonstrates the application potential. Participants in determining the use of a fair fund also follow a highly democratic procedure where all stakeholders involved eventually express a high level of satisfaction with the results facilitating the final decision making process. It ensures that plans for the distribution of such a fair fund were carefully thought out and justified with a multi-faceted nature that covers political, socio-economic, technical, environmental, public health, and industrial aspects.     

Multicriteria analysis as a tool to investigate compatibility between conservation and development on Salina Island,Aeolian Archipelago,Italy

Several multicriteria evaluation techniques have been developed since the 1970s. The need to compare different territorial policies has justified their introduction into environmental research. These methods are based on the numerical manipulation of heterogeneous information, which varies in terms of reference scale and type of measure (continuous, ordinal, qualitative, binary, etc.). During recent years, diverse investigations have focused on general conditions on Salina, the “green island” of the Aeolian archipelago. Such studies, within an interdisciplinary project, aimed to explore the possibility of implementing conservation strategies that are compatible with human needs, landscape preservation, and sustainable economic development. Three different evaluation techniques are applied, namely multicriteria weighted concordance and discordance analysis and a qualitative procedure. They are used to compare four alternative plans for the socioeconomic development of Salina Island. These plans lie between extreme alternatives: total protection of natural resources and maximizing economic development based on tourism. The plans are compared to each other on the basis of 14 criteria that reflect the socioenvironmental perception of Salina's inhabitants. The approach used in this research seems particularly fruitful because of its flexibility: it offers decision makers the chance to manage heterogeneous data and information that is not easily quantifiable. Such “soft” information helps to evaluate environmental conditions more precisely, and to make a less damaging choice among alternative development plans.     

Review and challenges of policies of environmental protection and sustainable development in China

China is confronted with the dual task of developing its national economy and protecting its ecological environment. Since the 1980s, China's policies on environmental protection and sustainable development have experienced five changes: (1) progression from the adoption of environmental protection as a basic state policy to the adoption of sustainable development strategy; (2) changing focus from pollution control to ecological conservation equally; (3) shifting from end-of-pipe treatment to source control; (4) moving from point source treatment to regional environmental governance; and (5) a turn away from administrative management-based approaches and towards a legal means and economic instruments-based approach. Since 1992, China has set down sustainable development as a basic national strategy. However, environmental pollution and ecological degradation in China have continued to be serious problems and have inflicted great damage on the economy and quality of life. The beginning of the 21st century is a critical juncture for China's efforts towards sustaining rapid economic development, intensifying environmental protection efforts, and curbing ecological degradation. As the largest developing country, China's policies on environmental protection and sustainable development will be of primary importance not only for China, but also the world. Realizing a completely well-off society by the year 2020 is seen as a crucial task by the Chinese government and an important goal for China's economic development in the new century, however, attaining it would require a four-fold increase over China's year 2000 GDP. Therefore, speeding up economic development is a major mission during the next two decades and doing so will bring great challenges in controlling depletion of natural resources and environmental pollution. By taking a critical look at the development of Chinese environmental policy, we try to determine how best to coordinate the relationship between the environment and the economy in order to improve quality of life and the sustainability of China's resources and environment. Examples of important measures include: adjustment of economic structure, reform of energy policy, development of environmental industry, pollution prevention and ecological conservation, capacity building, and international cooperation and public participation.
