System Dynamics to Sustainable Water Resources Management in the Eastern Snake Plain Aquifer Under Water Supply Uncertainty1

Abstract: Water supply uncertainty continues to threaten the reliability of regional water resources in the western United States. Climate variability and water dispute potentials induce water managers to develop proactive adaptive management strategies to mitigate future hydroclimate impacts. The Eastern Snake Plain Aquifer in the state of Idaho is also facing these challenges in the sense that population growth and economic development strongly depend on reliable water resources from underground storage. Drought and subsequent water conflict often drive scientific research and political agendas because water resources availability and aquifer management for a sustainable rural economy are of great interest. In this study, a system dynamics approach is applied to address dynamically complex problems with management of the aquifer and associated surface‐water and groundwater interactions. Recharge and discharge dynamics within the aquifer system are coded in an environmental modeling framework to identify long‐term behavior of aquifer responses to uncertain future hydrological variability. The research shows that the system dynamics approach is a promising modeling tool to develop sustainable water resources planning and management in a collaborative decision‐making framework and also to provide useful insights and alternative opportunities for operational management, policy support, and participatory strategic planning to mitigate future hydroclimate impacts in human dimensions.     

Indigenous economic institutions and ecological knowledge: A Ghanaian case study

Increasingly, the urgency of reorienting conventional development paradigms to take into account indigenous institutions and their ecological knowledge base is being recognized in both developed and developing countries. Based on a field research in Ghana, this paper discusses the nature and operation of indigenous economic institutions, their ecological knowledge, norms, beliefs, and practices pertaining to sustainable utilization of natural resources and environmental management. The institutions provide a framework of ideas, guiding principles, and practices that could serve as a foundation for endogenous options and broad-based efforts to solving resource and environmental management problems in the developing world. The paper also discusses limitations of indigenous ecological knowledge and practices.     

Using Multicriteria Methods in Environmental Planning and Management

In environmental planning and decision processes several alternatives are analyzed in terms of multiple noncommensurate criteria, and many different stakeholders with conflicting preferences are involved. Based on our experience in real-life applications, we discuss how multicriteria decision aid (MCDA) methods can be used successfully in such processes. MCDA methods support these processes by providing a framework for collecting, storing, and processing all relevant information, thus making the decision process traceable and transparent. It is therefore possible to understand and explain why, under several conflicting preferences, a particular decision was made. The MCDA framework also makes the requirements for new information explicit, thus supporting the allocation of resources for the process.     

Groundwater resource management and environmental protection

Population and economic developmental pressures will continue to put increasing pressure on the environment, especially on scarce water resources. Meanwhile, large numbers of poor families in the developing countries still lack access to safe water. An integrated water resource planning and policy analysis framework is presented that permits the main issues and alternative options to be systematically considered and prioritized, especially problems arising from groundwater pollution. Basic principles of water resource economics are used to illustrate how the neglect of long-term environmental considerations jeopardizes the availability and quality of groundwater resources in the Greater Manila area. This paper contains a brief overview of drinking water and sanitation issues in developing countries, presents a policy-oriented analysis of a groundwater problem of great relevance worldwide, and demonstrates how the study conclusions might be implemented practically in a constrained developing country context.     

Framework for Measuring Sustainable Development in Catchment Systems

Integrated catchment management represents an approach to managing the resources of a catchment by integrating environmental, economic, and social issues. It is aimed at deriving sustainable benefits for future generations, while protecting natural resources, particularly water, and minimizing possible adverse social, economic, and environmental consequences. Indicators of sustainable development, which summarize information for use in decision-making, are invaluable when trying to assess the diverse, interacting components of catchment processes and resource management actions. The Driving-Forces–Pressure–State–Impact–Response (DPSIR) indicator framework is useful for identifying and developing indicators of sustainable development for catchment management. Driving forces have been identified as the natural conditions occurring in a catchment and the level of development and economic activity. Pressures include the natural and anthropogenic supply of water, water demand, and water pollution. State indicators can be split into those of quantity and those of quality. Impacts include those that affect the ecosystems directly and those that impact the use value of the resource. It core indicators are identified within each of the categories given in the framework, most major catchment-based management issues can be evaluated. This framework is applied to identify key issues in catchment management in South Africa, and develop a set of indicators for evaluating catchments throughout the country.     

SELECTION AND SUSTAINABILITY OF LAND AND WATER RESOURCE MANAGEMENT SYSTEMS1

ABSTRACT: Most spatial decision support systems for natural resource planning and management are limited by their scenario-based (non-behavioral), deterministic (non-stochastic) structure. A spatial decision support system is developed that uses a multiple attribute decision-making model to explain how a property manager selects a land and water resource management system (LWRMS) based on its multiple, stochastic economic and environmental attributes. The decision support system assesses sustainable resource management at the property and watershed scales and identifies the most cost-effective policy for enhancing sustainable resource management. Economic attributes are determined with an economic model and environmental attributes are simulated with an environmental model. Input parameters for both models are generated with a geographic information system. The decision support system is used to rank five LWRMS for a sample of 20 farmers in Missouri's Goodwater Creek watershed and for two hypothetical watershed alliance groups. Results indicate that the average farmer and the two alliance groups would rank the five LWRMS in the same manner. From the viewpoint of the watershed alliance, the most preferred LWRMS for the average farmer in the watershed is sustainable.     

Multiple-resource modeling as a tool for conservation: Its applicability in Mexico

The current Mexican environmental law provides the legal basis for comprehensive land-use planning. Under the law, development of natural ecosystems must combine goals, policies, and practices towards the sustainable use of natural resources and the protection of biological diversity. Thus, ecosystem manipulation must be able to counter fragmentation of natural ecosystems and isolation of natural reserves, while providing for human needs. Assessment of the potential of natural ecosystems and management impacts are required. Multiple-resource simulation is an assessment and land-use planning tool that permits managers and decision makers to comply with the law, providing a flexible, user-oriented system that can meet the needs of managers, conservationists, and researchers. A multiple-resource model and an example of how it can be applied to meet planning needs is presented for discussion.     

Realizing the Potential of Ecosystem Services: A Framework for Relating Ecological Changes to Economic Benefits

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.     

Greening the Brazil,Russia, India,China and South Africa (BRICS) economies: Assessing the impact of electricity consumption,natural resources,and renewable energy on environmental footprint

Electricity consumption is a crucial factor in the environmental pollution process, and therefore, its impact needs to be carefully considered by policymakers. This study investigates the relationship between energy consumption, electricity generation, natural resource utilization, and environmental pollution in BRICS nations, which have a substantial share in global resource consumption. To this end, we employed a novel methodology, namely the Method of Moment Quantile Regression (MMQR), for the time period between 1990 and 2018, within the framework of the Environmental Kuznets Curve (EKC) theory. The study's outcome shows that natural resources and renewable energy are efficacious and significant in curbing environmental degradation among the sample countries. The investigation reveals a positive correlation between electricity consumption and environmental degradation, thereby highlighting this vital resource's role in exacerbating the BRICS nations’ ecological footprint. The findings from this research can provide crucial insights for policymakers to achieve sustainable development and carbon neutrality in these countries.     

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.     

Drivers of agricultural sustainability in developing countries: a review

Agricultural development has been an effective instrument for poverty alleviation and economic development in developing countries over the latter half of the twentieth century, and over 80 % of rural people globally still depend on agriculture for their living. However, issues such as water availability, land degradation and an increasing dependence on chemical fertilisers and pesticides continue to be on-going threats to sustainable agricultural development. These threats are being driven by the pressing need to ensure food security in the face of rapidly growing and urbanising populations. Developing countries will therefore continue to need improved methods for planning sustainable agricultural development. This paper presents a review of agricultural sustainability assessment in developing countries. The review highlights some of the key weaknesses that persist in sustainability assessment and the need to consider not only indicators of sustainability but also the drivers that influence indicator behaviour. We argue that without a good understanding of the drivers of sustainability and their systemic relationships to indicators, sustainability assessments run the risk of focusing on symptoms without addressing underlying causes of adverse indicator trends. Drivers of agricultural sustainability in developing countries encompass a range of demographic, natural, socio-economic, political, institutional and management factors. Understanding these and their relationships to sustainability indicators is needed in order to develop agricultural development policy that supports sustainability. The paper presents a conceptual framework for guiding systemic agricultural sustainability assessment and agricultural development planning in developing countries that includes both sustainability indicators and drives, and considers the broad relationships between them.     

Environmental policy for sustainable development of natural resources

This paper describes new environmental policies and expanded administrative agencies which in recent years have been adopted by many governments faced with a continuing decline in the quality of their environments. In a number of developed and developing countries, devising a far reaching environmental policy for sustainable development of the natural resources sector is a national priority. Specific environmental policies may be classified according to objectives, timeframe, mechanisms for implementation, whether or not they are binding, and the nature of sanction. This paper provides some generalizations about certain features common to most environmental policies. In the first section an examination is made of some of the most pressing problems which environmental policies relating to natural resources seek to address. The second section discusses environmental policies themselves. The third section, which makes up the main body of the paper, assesses the strengths and weaknesses of a variety of mechanisms available for implementing environmental policies to promote sustainable development in the natural resources sector.     

Sustaining Jamaica's forests: The protected areas resource conservation project

This study examines Jamaica's attempt to protect a tropical forest reserve. The biophysical setting, and the types and magnitude of forest development pressures are reviewed. Next, Jamaica's approach to developing new land-use strategies and compatible environmental protection and economic development programs are examined. Finally, the practical and theoretical implications by which institutions can be designed to encourage planning for sustainable development are reviewed. The implications suggest how to provide an appropriate mix of cooperation and market competition, by which people acting in their own interests accomplish socially equitable economic development, while protecting the environment for the benefit of future generations. The experience illustrates that effective long-term protection of natural areas requires the building of local relationships and support, the development of local economic activities supportive of conservation, the defining of clear boundaries, and significant monitoring and enforcement. Long-term protection of the Blue and John Crow mountains, and other important natural areas of Jamaica, will also require the development of a workable and enforceable system of land-use planning for the island, and adjustments to the economic incentive structure so that sustainable, nonextractive uses of natural capital are placed on equal footing with other economic uses (e.g., coffee production).     

Wise Use of Wetlands: Current State of Protection and Utilization of Chinese Wetlands and Recommendations for Improvement

Wetland protection and utilization sometimes appear to be in conflict, but promoting the wise use of wetlands can solve this problem. All countries face the challenge of sustainable development of wetlands to a greater or lesser extent, but the problem is especially urgent in developing countries, such as China, that want to accelerate their economic development without excessive environmental cost. Chinese wetlands contribute greatly to economic development, but improper use of these natural resources has endangered their existence. It is thus necessary to provide scientific guidance to managers and users of wetlands. In this paper, we analyze the present status of Chinese wetland protection and utilization, and discuss problems in six categories: a lack of public awareness of the need for wetland protection; insufficient funding for wetland protection and management; an imperfect legal system to protect wetlands; insufficient wetland research; lack of coordination among agencies and unclear responsibilities; and undeveloped technologies related to wetland use and protection. The wise use of Chinese wetlands will require improvements in four main areas: increased wetland utilization research, scientific management of wetland utilization, improved laws and regulations to protect wetlands, and wider dissemination of wetland knowledge. Based on these categories, we propose a framework for the optimization of wetland use by industry to provide guidance for China and other countries that cannot sacrifice economic benefits to protect their wetlands.

ENVIRONMENT AND RESOURCE POLICY IN DEVELOPING COUNTRIES

This article analyzes the official and non-official responses of Filipinos to the depletion of some renewable natural resources (particularly water quality). Contrary to popular assumption, and contrary to official statements of the Philippine government at international conferences, it appears that environmental depletion is a political issue in the Philippines. The reasons for the salience of resource and environmental issues are discussed. The dilemma of the Philippine government is that it is committed to economic progress, but the resources which make that progress possible are in short supply. Timber, soil and clean water are endangered by deforestation, erosion and pollution. However, conservation and environmental protection are expensive in the short run. The Philippines faces a problem common to developing tropical countries.     

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.     

Sustainable Water Resources Management in a Conflict Resolution Framework1

Abstract: A decision support system for sustainable water resources management in a water conflict resolution framework is developed to identify and evaluate a range of acceptable alternatives for the Geum River Basin in Korea and to facilitate strategies that will result in sustainable water resource management. Working with stakeholders in a “shared vision modeling” framework, sustainable management strategies are created to illustrate system tradeoffs as well as long‐term system planning. A multi‐criterion decision‐making (MCDM) approach using subjective scales is utilized to evaluate the complex water resource allocation and management tradeoffs between stakeholders and system objectives. The procedures used in this study include the development of a “shared vision model,” a simulated decision‐making support system (as a tool for sustainable water management strategies associated with water conflicts, management options, and planning criteria), and the application of MCDM techniques for evaluating alternatives provided by the model. The research results demonstrate the utility of the sustainable water resource management model in aid of MCDM techniques in facilitating flexibility during initial stages of alternative identification and evaluation in a basin suffering from severe water conflicts.

Regional climatic mapping as a tool for sustainable development

In the framework of an EU project on sustainable village development in China (SUCCESS), the natural climate resource was evaluated. Climate is seen as a potential for sustainability, an improvement of social life, agricultural production and reduction of air pollution problems. In this respect, thermal comfort conditions, microclimates and ventilation patterns were studied in seven Chinese villages and climate maps were drawn. Following planning recommendations, they can be transferred to decision-makers for their village development. In this framework, the paper presents a general methodology of urban climate mapping, carried out in China, applicable to all countries and climates.
