WATER RESOURCES DEVELOPMENT IN AN ENVIRONMENTALLY-CONSCIOUS ERA1

The Sierra Club, which has long fought selected water resource projects that it believes would be environmentally damaging, has come to the conclusion in recent years that much more basic reforms are required in water resources development activities if the demands for environmental quality now evidenced by the American people are to be satisfied. These reforms should not be limited to those that would have a direct effect on the environmental aspects of proposed projects, but also many others long advocated by the economics profession that would have favorable indirect effects. Among the urgent reforms with indirect effects are those involving revision of the procedures used in evaluating proposed projects. These procedures should be revised so that future evaluations will much more accurately reflect the economic and environmental merits of proposed projects. Basic reforms of tax policies are also needed that will eliminate most of the private profit available to those who can persuade the government to increase the value of their land through the construction of water projects. Finally, some additional actions can be taken that will have a direct impact on lessening the adverse environmental impact of water projects beyond the provisions of the National Environmental Policy Act of 1969.     

Financing water supply and sanitation under Agenda 21

This paper assesses the financing challenges which have to be met by developing countries if water resources are to be managed efficiently, if the quality of the aquatic environment is to be improved and if water related services are to be delivered in a responsive, efficient and equitable way. This paper takes the view that attaching 'price tags' to water supply and sanitation, as was tentatively done in Agenda 21, is a misguided approach and that what is needed is articulation of clear principles which should underpin the financing of water supply and sanitation investments. To illustrate the approach the paper focuses heavily on experiences from World Bank water supply, sanitation and urban development projects over the past 30 years. The challenge is to develop appropriate institutional and financial arrangements. The essence of such arrangements is that they ensure that societies mobilize appropriate levels of resources for providing water related environmental services and that these resources are used in the most efficient and effective way possible .     

Planning for change and sustainability in water development in Lao PDR and the Mekong River basin

With its recent opening to the global market economy, the natural resources of the Lao People's Democratic Republic (Lao PDR, referred to in this paper as Laos) – especially its water resources–have attracted external interest and investment. The overall level of water development is low. While even modest development would help Laos meet some of its urgent needs, past experience in Southeast Asia and other tropical regions suggests that fast-paced water development may damage the natural resource base. This article examines some efforts in water development from Southeast Asia and other regions and their relevance to water policy formulation in Laos. Future social and environmental changes in Laos are inevitable, but the nature and direction of these changes are uncertain. It thus makes sense to design policies that are flexible and can be adjusted to, and even take advantage of, a changing social and environmental context. Smaller-scale, deliberately-paced projects which merge local knowledge and external expertise fulfil the requirements of flexibility and adjustability, and are also appropriate for other important reasons: they do not require massive inputs of funding, and they do not initiate large-scale environmental and socio-economic changes. Current knowledge of the complex ecological and social systems in Laos is only sketchy. A slower-paced development will allow developers the necessary time to learn more about these important aspects.     

跨流域调水的公正问题——基于环境正义的分析视角

水资源时空分布不均造成的水资源短缺问题已成为阻碍区域发展的重要因素。为了应对区域间的水资源短缺问题,跨流域调水工程作为不同流域水资源优化配置的一种手段,被广泛用于解决水资源分配不均和区域需水不平衡问题。调水工程虽然短期内缓解了水资源压力,平衡了区域间用水需求,但其建设和运营过程对工程所涉区域的地方经济、地理环境、人文环境以及生态环境也造成不同程度的压力。本文通过对当前世界范围内跨流域调水工程的文献回顾,围绕跨流域调水工程所引发的社会公平正义层面的争议,借助环境正义理论的分析方法,通过对国内外调水案例的实践分析,追踪相关环境不公的现象和争议,剖析当前社会—生态冲突的产生机制。最后从我国水生态文明建设实际出发,提出以建立健全水权交易市场,构建"赋权—认同—合作"参与机制和树立"人类命运共同体"理念的解决对策,以期降低调水工程对环境和社会所造成的负面影响,推进水生态正义体系的建设。     

An examination of the compatibility of World Bank policies towards population, development and biodiversity in the Third World

This paper addresses the compatibility of World Bank policies towards population growth, development and biodiversity in the Third World. The World Bank has been central to the design and implementation of the Global Environment Facility (GEF), the remit of which includes the conservation of global biodiversity. However, the Bank's influence over the facility has in itself created controversy which may undermine its effectiveness. More significantly, the Bank's commitment to the GEF is subverted by its policies in other social and economic sectors. The World Bank, together with the International Monetary Fund (IMF), directs the structural adjustment of Third World economies through economic deregulation and privatization. This approach exacerbates inequalities and further empowers large landowners who may then displace tenant farmers and claim exclusive rights to former common land. Thus, biodiversity loss occurs as large landowners reorientate the land use towards the production of export goods and dispossessed farmers invade marginal land. Population growth influences biodiversity loss through its contribution to agricultural intensification and the settlement of marginal land. The World Bank encourages this trend through its non-committal approach to population control, but more especially through structural adjustment's positive effect on fertility.

水电站的建设会造成坝址下游河段减水,对水环境和水生生物造成不利影响,因此电站生态流量的确定和泄放措施的可行性对于维护河流生态环境至关重要。以硕曲河去学水电站为例,基于可行性研究阶段提出的生态流量泄放措施方案,采用数学模型和理论分析方法,从生态流量取水水温、泄洪洞事故条件下生态流量保证率以及水资源的合理高效利用等方面进一步对生态流量泄放方案进行了优化比选。提出的优化方案提高了生态流量取水口的布置高程,在泄洪洞之外单独布置生态泄放系统,并增设生态流量发电机组等。对比分析表明,该优化方案在改善生态流量的下泄水温、提高生态流量泄放保证率、合理高效利用水能资源等方面具有较大优势。本研究为水电工程中生态流量泄放措施保障等方面提供了科学依据和技术参考。     

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.     

SOCIAL WELL-BEING AND WATER RESOURCES PLANNING1

ABSTRACT: For many years, Federal water resources projects have been subjected to benefit-cost analysis to establish their economic feasibility. Several years ago social well-being was added as a consideration. This paper discusses the state-of-the-art in analyzing and evaluating aspects of social well-being. It stresses current short-falls and advocates a direction for further efforts.     

Environmental sustainability in an agricultural development project: a system dynamics approach

Regional agricultural projects based on water resource development have many potential impacts on social and natural environments. In this research, potential long-term environmental problems of the Southeastern Anatolian Project (GAP) related to water resources, land use, land degradation, agricultural pollution and demography are analysed from a systems perspective. The analysis focuses on the totality of environmental, social and economic issues. For this purpose, a system dynamics simulation model (GAPSIM) has been developed as an experimental platform for policy analysis. GAPSIM was validated, first 'structurally', using the tests suggested by the literature and then the model 'behaviour' was tested and calibrated with respect to available data. The reference behaviour of GAPSIM reveals that, as the irrigated lands are developed, GAP faces significant water scarcity because of the increased intensity of cotton, the crop with the highest demands for water. Simulation results also indicate that two key environmental factors, pesticide and fertilizer consumption may reach undesirable levels. Alternative irrigation water release strategies, development rates of irrigated fields and farm rotation practices appear as important policy tools in achieving long-term environmental sustainability. GAPSIM promises to be not only a useful laboratory for policy makers of GAP, but also a useful generic structure applicable to other similar regional development projects.     

Exporting dams: China's hydropower industry goes global

In line with China's "going out" strategy, China's dam industry has in recent years significantly expanded its involvement in overseas markets. The Chinese Export-Import Bank and other Chinese financial institutions, state-owned enterprises, and private firms are now involved in at least 93 major dam projects overseas. The Chinese government sees the new global role played by China's dam industry as a "win-win" situation for China and host countries involved. But evidence from project sites such as the Merowe Dam in Sudan demonstrates that these dams have unrecognized social and environmental costs for host communities. Chinese dam builders have yet to adopt internationally accepted social and environmental standards for large infrastructure development that can assure these costs are adequately taken into account. But the Chinese government is becoming increasingly aware of the challenge and the necessity of promoting environmentally and socially sound investments overseas.     

关于世行贷款农业灌溉项目环境影响评价问题的讨论

农业灌溉工程建设是我国第十二个五年规划纲要中提出的全面加强农田水利建设工作的重要组成部分。随着越来越多农业灌溉项目的兴建及我国环境影响评价制度的发展,农业灌溉项目的环境影响评价也在不断发展和完善中。本文根据世行贷款项目——中国四川武都农业灌溉项目环境影响评价实践和工作经验,分析总结了世界银行及我国在农业灌溉项目环境影响评价工作方面的特点和要求,其中世界银行在有些方面,如评价等级、公众参与等与国内环评要求基本一致,而有些方面,如回顾性评价、替代方案分析、累积性影响分析、环境管理计划、移民安置行动计划、病虫害管理计划等在国内环境影响评价中尚未引起足够的关注或与世界银行要求存在较大差异,值得我国环评工作参考和借鉴。     

A study on operation problems of hydropower plants integrated with irrigation schemes operated in Turkey

In this study, Hydroelectric Power Plants, which have been built and integrated with irrigation schemes by the State Hydraulic Works which is a government agency and private companies in Turkey, have been examined. Technical, environmental, structural and social problems encountered during their operation have been analyzed, and appropriate solution proposals have been presented in the study for a sustainable irrigation and Hydroelectric Power Plant operation. Consequently, Hydroelectric Power Plants which have been integrated with irrigation schemes should be operated efficiently and they should be operated in attenuation with the environment. However, when hydroelectric projects are developed without preparing their necessary integrated basin management plans, then this will cause environmental, operation and maintenance, administrative, monitoring and evaluation problems. In order to ensure sustainability of hydroelectricity production and also in order to use water resources more efficiently for irrigation; it is very important to find permanent solutions to these problems.     

THE SOCIAL CONTEXT OF WESTERN WATER DEVELOPMENT1

ABSTRACT: Social scientists were included in the planning and design for an integrated, trans-basin water resource project. Within this complex project, a socioeconomic impact assessment (SIA) concentrated on identifying the social, political, and economic issues and potential impacts inherent in developing a city's water rights. Before the SIA began, some of the development alternatives had already generated widespread hostility and organized opposition from communities within the watershed. The SIA involved residents of affected communities in the study design and project planning. The study found a number of components that constituted the concerns, beliefs, and expectations about perceived, potential impacts that might result from the different alternatives. In most cases these issues constituted threats to valued environmental resources, valued community resources, the social environment, the economic base, and a secure future. The social science component was a key factor in the ultimate decision to pursue a particular alternative which was sensitive to the social and political issues, minimized environmental and socioeconomic impacts, and ultimately had support among the communities potentially affected. The experience from this case study suggests that the approach used can be applied successfully in the planning of other water development projects and result in cooperation from the wide range of interest groups that often present costly obstacles to such projects.     

APPROACHES TO WATER RESOURCE POLICY AND PLANNING IN TEXAS1

ABSTRACT: Texas is one of the states in which limitations in water supplies could severely constrain economic growth in certain areas. The traditional planning approach for addressing this problem has involved devising schemes for large water development projects, which for many years included the importation of water from other states. Now the attitude towards water resource management is changing, and it is generally agreed that better management of existing supplies is the preferred approach. In this paper we review some of the changes that have recently occurred in Texas, including attempts to streamline the water institutions in such a way that they might be more responsive to the need for more comprehensive management of water resources statewide, with greater emphasis on social and environmental concerns.     

Economic degradation, conservation and allocation of water resources

Economic stagnation and hyper-inflation, in part the result of the need to service huge foreign debts, have taken their toll on the infrastructure and government institutions of Latin America. Both have been starved of financial resources. In some ways the water sector has been affected more than others because water and the environment are seen as free public goods which can be used without regard to cost. Even though internal financial resources are limited there are still opportunities to address the water and environmental problem at the national level, and some recommendations are made in this regard. Nevertheless, major inputs from the developed countries will be needed because the protection of environment and water resources is both a national and global issue.     

Dilemmas and advances in corporate social responsibility in Brazil. The work of the Ethos Institute

This article discusses the development of corporate social responsibility (CSR) in Brazil from the perspective of the Ethos Institute of Business and Social Responsibility. The Institute is a not‐for‐profit, non‐governmental organization, that has played a leading role in the Brazilian CSR effort. In Brazil, CSR initiatives have a long tradition of philanthropy, a consequence of the country's great social inequalities. The increased attention to corporate social responsibility has paralleled growing concern about sustainable development and the intensifying activities of pressure groups (consumers, customers, investors, NGOs, labour unions, the media, among others) that have been increasing since the 1990s as natural resources are progressively becoming exhausted, social tensions rising and environmental conditions deteriorating worldwide. This article identifies problems and obstacles to the growth of corporate social responsibility in Brazil, as well as advances and alternatives for CSR and towards creating conditions for the country to be internationally competitive and sustainable in the financial, social and environmental areas.     

Water Footprint of the Palestinians in the West Bank1

Abstract: Water in the West Bank of Palestine is a key issue due to its limited availability. Water is used from own sources for domestic, industrial, and agricultural purposes. Moreover, water is consumed in its virtual form through consumption of imported goods, such as crops and livestock, the production of which used water in the country of production. In addition, wastewater in many parts of the West Bank is disposed off without treatment into the wadis, deteriorating the quality of the water resources in the area and, therefore, further reducing the quantity of good quality water available. This paper calculates the water footprint for the West Bank. The consumption component of the water footprint of the West Bank was found to be 2,791 million m³/year. Approximately 52% of this is virtual water consumed through imported goods. The West Bank per capita consumption component of the water footprint was found to be 1,116 m³/cap/year, while the global average is 1,243 m³/cap/year. Out of this number 50 m³/cap/year was withdrawn from water resources available in the area. Only 16 m³/cap/year (1.4%) was used for domestic purposes. This number is extremely low and only 28% of the global average and 21% of the Israeli domestic water use. The contamination component of the water footprint was not quantified but was believed to be many times larger than the consumption component. According to the official definition of water scarcity, the West Bank is suffering from a severe water scarcity. Therefore, there is a need for a completely new approach towards water management in the West Bank, whereby return flows are viewed as a resource and that is geared towards a conservation oriented approach of “use, treat, and reuse.”     

SOCIOLOGICAL ASPECTS OF WATER DEVELOPMENT1

Decisions to develop water resources systems so far have been primarily taken on the basis of engineering and economic feasibilities. Very rarely, if ever, sociological feasibility has been considered, except in a very broad sense. Planning is for the people, and it should improve the quality of life. Hence, it is argued that water resources decisions ought to be primarily social ones, and that the success or failure of any resource development should not only be judged by its techno-economic excellence but also by its impact on people. Water resources planning process is discussed, and the difficulties associated with the evaluation of sociological feasibility of projects are enumerated. The social consequences of water development projects are traced through planning, construction, operation and management impacts. Finally, it is suggested that the foremost factor in the success of any water management program is the public understanding and acceptance of that program.     

Bioenergy project appraisal in sub‐Saharan Africa: Sustainability barriers and opportunities in Zambia

Although there is continuing debate surrounding biofuel cultivation (especially in developing nations) in relation to issues of exploitation, land grabbing, poverty alleviation and energy security, there is a lack of empirical evidence to assess how these debates are playing out in practice on the ground. Drawing on political ecology discourse, this paper examines case studies of biofuel production in Zambia and the effects they have on environmental and social sustainability. During April and May 2011, data were collected on two case study projects involving Jatrophacurcas feedstock cultivation in Zambia. Semi‐structured interviews were used to ascertain views from affected stakeholders (local farmers, local environmental, social, and agronomic experts, and investors) on the biofuel projects and their environmental and social impacts. The findings suggest that the uneven distribution of costs and benefits are brought about by imbalances in knowledge, access to resources and the allocation of social and political influence (often associated with broader discourses of development), and this provides a likely rationale for a lack of sustainability in biofuel projects. Drawing on these viewpoints, as well as on field observations, this paper outlines the barriers and opportunities linked to Jatrophacurcas project sustainability.     

River Restoration in Spain: Theoretical and Practical Approach in the Context of the European Water Framework Directive

River restoration is becoming a priority in many countries because of increasing the awareness of environmental degradation. In Europe, the EU Water Framework Directive (WFD) has significantly reinforced river restoration, encouraging the improvement of ecological status for water bodies. To fulfill the WFD requirements, the Spanish Ministry of the Environment developed in 2006 a National Strategy for River Restoration whose design and implementation are described in this paper. At the same time many restoration projects have been conducted, and sixty of them have been evaluated in terms of stated objectives and pressures and implemented restoration measures. Riparian vegetation enhancement, weir removal and fish passes were the most frequently implemented restoration measures, although the greatest pressures came from hydrologic alteration caused by flow regulation for irrigation purposes. Water deficits in quantity and quality associated with uncontrolled water demands seriously affect Mediterranean rivers and represent the main constraint to achieving good ecological status of Spanish rivers, most of them intensively regulated. Proper environmental allocation of in-stream flows would need deep restrictions in agricultural water use which seem to be of very difficult social acceptance. This situation highlights the need to integrate land-use and rural development policies with water resources and river management, and identifies additional difficulties in achieving the WFD objectives and good ecological status of rivers in Mediterranean countries.
