Finding Water for Growth: New Sources,New Tools,New Challenges1

Abstract: Rapidly growing regions such as the western United States face difficult challenges in mobilizing new water supplies to meet new demands. Environmental concerns have curtailed the scope for large new surface storage projects, and widespread basin overdraft has limited ground water’s potential as a source of expansion. Drawing on the California experience, this article explores modern water planning approaches, which focus on a portfolio of options including nontraditional sources (recycling, desalination, underground storage) and more efficient use of existing supplies (conservation and water marketing). It reviews the advantages and drawbacks of the elements of the portfolio, provides examples of innovative planning approaches, and assesses the role for supportive government policies.     

基于RAGA-AHP的工业行业土地集约利用评价——以江苏省为例

作为建设用地的重要组成部分,工业用地的节约集约利用直接影响到建设用地特别是城市土地利用和管理的效果。基于行业视角的工业行业土地集约利用评价能分析工业行业土地集约利用现状,揭示不同工业行业土地集约利用的差异,为制定工业行业土地集约利用控制标准提供参考。论文通过构建包含用地结构、用地强度、用地投入和用地产出在内的4个子目标、11个指标的工业行业土地集约利用评价指标体系,采用RAGA-AHP方法实现了江苏省工业行业土地集约利用评价。研究结果表明,实码加速遗传算法与层次分析法的集成,能获得高精度的权数并能保证全局收敛性;江苏省工业行业总体的土地集约利用水平较低。通信设备、计算机及其他电子设备制造业的集约度最高,为76.74;饮料制造业的土地集约度最低,仅13.42。不同行业的土地集约利用水平存在差异,且归属于同一类别的不同行业之间的土地集约利用水平差异不大,归属于不同类别的行业之间的土地集约利用水平差异显著。     

中国三类自然资本的关键性检验与分析:1949-2007年

论文围绕关键自然资本的测算、"关键性"假设检验及案例展开,研究指出:随着观察期的延长,中国境内自然资本与物质资本的互补性不断下降,从20 a来看,淡水、化石能源及生产性土地具有物质资本无法替代的影响效力;中长期回归式中关键自然资本的回归系数为负数,由于生产性足迹描述关键自然资本开采情况,故而当下我国关键自然资本开采水平对可持续发展较不利。以此为据,估算南水北调工程引发相关区域淡水变动对当地可持续发展的影响,结果显示:受水区福利的增加对应着水源区福利的下降,南水北调东、中线工程缓和了受水区关键自然资本不可持续开采的压力,增加了水源区承担的关键自然资本不可持续式开采负外部性。     

Cost‐Effective Placement of Best Management Practices in a Watershed: Lessons Learned from Conservation Effects Assessment Project

This article reviews the key, cross‐cutting findings concerning watershed‐scale cost‐effective placement of best management practices (BMPs) emerging from the National Institute of Food and Agriculture Conservation Effects Assessment Project (CEAP) competitive grants watershed studies. The synthesis focuses on two fundamental aspects of the cost‐effectiveness problem: (1) how to assess the location‐ and farmer‐specific costs of BMP implementation, and (2) how to decide on which BMPs need to be implemented and where within a given watershed. Major lessons learned are that (1) data availability remains a significant limiting factor in capturing within‐watershed BMP cost variability; (2) strong watershed community connections help overcome the cost estimation challenges; (3) detailing cost components facilitates the transferability of estimates to alternative locations and/or economic conditions; and (4) implicit costs vary significantly across space and farmers. Furthermore, CEAP studies showed that (5) evolutionary algorithms provide workable ways to identify cost‐effective BMP placements; (6) tradeoffs between total conservation costs and watershed‐scale cost‐effective water quality improvements are commonly large; (7) quality baseline information is essential to solving cost‐effectiveness problem; and (8) systemic and modeling uncertainties alter cost‐effective BMP placements considerably.     

以珠三角地区为例分析实施生态经济战略的重大效益

本文基于第一线调研和多年参政议政工作基础上,对珠三角区域的城市工业生态经济战略实施的过程、途径,可行性、原理及获得的重大效益进行了介绍与总结分析。研究指出,在实践过程中为更快更大规模地把生态经济战略与各地实际发展进程相结合加以推广和实施,则必须具备高度的社会责任感,勇于运用各种机会把生态经济的战略思路和实施策略很好地向社会各层面以及政府部门反映和建言,才能取得最好及更大的成效。     

The trouble with tanks: unsettling dominant Australian urban water management paradigms

Over the course of Australia's Millennium Drought, urban water managers gained more appreciation of householders' willingness and capacities to respond to water shortages and restrictions, including by installing rainwater tanks (RWTs) for watering gardens. How urban water managers regard tanks and tank users gives insight into their understandings of social sustainability, as found in interviews conducted in 2006 and 2010. These also revealed a growing distance between policymakers and water providers pursuing a broader approach to sustainability in their communities. The RWT is considered here as a limit case for paradigms of urban water management: it challenges conventional distinctions (such as provider/consumer) and heralds a new hydropolitics. These challenges are discussed as seven kinds of trouble with tanks: (1) incompatibility with the management model and vision of modernity enshrined in the ideal of centralised provision in control of accredited water experts; (2) anxieties about control and risk aroused by these private on-site facilities and their non-expert users; (3) equivocation over their environmental effects, normally assessed in hydrological terms that downplay the benefits of green streetscapes; (4) inexplicability of their popularity within dominant economically rationalist models of customers; (5) educational effects that exceed rationalist, individualist models of learning and require more socially realistic, culturally intelligent and practice-oriented approaches; (6) generation of enthusiasms that are spurned as threats to rationality instead of harnessed to energise the sustainability journey and (7) community-building effects that are unthinkable within the neoliberal customer paradigm but graspable to water managers through lay concepts like “dinner table conversations”.     

抓住机遇 迎接挑战 协同发展 "天人合一"

论述了中国入世对长江流域可持续发展所带来的影响、机遇和挑战，讨论了可持续发展思想的内涵及影响长江流域可持续发展的重要问题。认为可持续发展思想应包含：当代人要重视发展和持续性，不断提高人群生活质量和资源环境的承载能力，满足当代人的需求又不损害后代人的需求，满足一个地区、国家的需求又不损害别的地区、国家的需求，并努力补救上代人所留下的资源、环境创伤。我们应认识七种要素：人口、资源、环境、经济、社会、知识和文化之间的内在关系，必须协同处理。自然资源是发展的基础。中国开展环境保护工作已有20多年，特别是改革开放以来取得很多进展，目前需对严重环境问题采取更有力的措施。讨论了中国入世后面临的企业、农业、人才资源、高新技术产业、政府管理体制的创新和法制建设等问题，并着重研究了可持续发展文明观、加强绿色管理和绿色产品开发、知识经济和环保产业等关键问题。     

Benefit‐Cost Analysis of Integrated Water Resource Management: Accounting for Interdependence in the Yakima Basin Integrated Plan

Integrated water resource management (IWRM) requires accounting for many interrelated facets of water systems, water uses and stakeholders, and water management activities. The consequence is that project analysis must account for the nonseparability among the component parts of IWRM plans. This article presents a benefit‐cost (B‐C) analysis of a set of projects included in the Yakima Basin Integrated Plan proposed for the Yakima Basin in south‐central Washington State. The analysis accounts for interdependence among proposed water storage projects and between water storage and water market development in the context of historical and more adverse projected future climate scenarios. Focusing on irrigation benefits from storage, we show that the value of a given proposed storage project is lower when other proposed storage projects in the basin are implemented, and when water markets are functioning effectively. We find that none of the water storage projects satisfy a B‐C criterion, and that assuring proposed instream flow augmentation is less expensive by purchasing senior diversion rights than relying on new storage to provide it.     

Mountain substitutability and peak load pricing of high alpine peaks as a management tool to reduce environmental damage: A contingent valuation study

High alpine peaks throughout the world are under increasing environmental pressure from hikers, trekkers, and climbers. Colorado's “Fourteeners”, peaks with summits above 14,000 feet are no exception. Most of these peaks have no entrance fees, and reach ecological and social carrying capacity on weekends. This paper illustrates how a series of dichotomous choice contingent valuation questions can be used to evaluate substitutability between different alpine peaks and quantify the price responsiveness to an entrance fee. Using this approach, we find that peak load pricing would decrease use of popular Fourteeners in Colorado by 22%. This reduction is due almost entirely to substitution, rather than income effects. There is also price inelastic demand, as 60% of the hikers find no substitution for their specific Fourteener at the varying cost increases posed in the survey. The no substitute group has a mean net benefit of $294 per hiker, per trip, considerably higher than visitor net benefits in most recreational use studies.
