Water Quality Improvement Policies: Lessons Learned from the Implementation of Proposition O in Los Angeles,California 总被引:1,自引:0,他引:1
This article evaluates the implementation of Proposition O, a stormwater cleanup measure, in Los Angeles, California. The
measure was intended to create new funding to help the city comply with the Total Maximum Daily Load requirements under the
federal Clean Water Act. Funding water quality objectives through a bond measure was necessary because the city had insufficient
revenues to deploy new projects in its budget. The bond initiative required a supermajority vote (two-thirds of the voters),
hence the public had to be convinced that such funding both was necessary and would be effective. The bond act language included
project solicitation from the public, as well as multiple benefit objectives. Accordingly, nonprofit organizations mobilized
to present projects that included creating new parks, using schoolyards for flood control and groundwater recharge, and replacing
parking lots with permeable surfaces, among others. Yet few, if any, of these projects were retained for funding, as the city
itself also had a list of priorities and higher technical expertise in justifying them as delivering water quality improvements.
Our case study of the implementation of Proposition O points to the potentially different priorities for the renovation of
urban infrastructure that are held by nonprofit organizations and city agencies and the importance of structuring public processes
clearly so that there are no misimpressions about funding and implementation responsibilities that can lead to disillusionment
with government, especially under conditions of fiscal constraints. 相似文献

Lyubov A. Kurkalova 《Journal of the American Water Resources Association》2015,51(2):359-372
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. 相似文献

Community-based coastal resource management has been widely applied within the Philippines. However, small-scale community-based reserves are often inefficient owing to management inadequacies arising because of a lack of local support or enforcement or poor design. Because there are many potential pitfalls during the establishment of even small community-based reserves, it is important for coastal managers, communities, and facilitating institutions to have access to a summary of the key factors for success. Reviewing relevant literature, we present a framework of lessons learned during the establishment of protected areas, mainly in the Philippines. The framework contains summary guidance on the importance of (1) an island location, (2) small community population size, (3) minimal effect of land-based development, (4) application of a bottom-up approach, (5) an external facilitating institution, (6) acquisition of title, (7) use of a scientific information database, (8) stakeholder involvement, (9) the establishment of legislation, (10) community empowerment, (11) alternative livelihood schemes, (12) surveillance, (13) tangible management results, (14) continued involvement of external groups after reserve establishment, and (15) small-scale project expansion.These framework components guided the establishment of a community-based protected area at Danjugan Island, Negros Occidental, Philippines. This case study showed that the framework was a useful guide that led to establishing and implementing a community-based marine reserve. Evaluation of the reserve using standard criteria developed for the Philippines shows that the Danjugan Island protected area can be considered successful and sustainable. At Danjugan Island, all of the lessons synthesized in the framework were important and should be considered elsewhere, even for relatively small projects. As shown in previous projects in the Philippines, local involvement and stewardship of the protected area appeared particularly important for its successful implementation. The involvement of external organizations also seemed to have a key role in the success of the Danjugan Island project by guiding local decision-makers in the sociobiological principles of establishing protected areas. However, the relative importance of each component of the framework will vary between coastal management initiatives both within the Philippines and across the wider Asian region.Published on line 相似文献

Improvements on Flood Alleviation in Germany: Lessons Learned from the Elbe Flood in August 2002 总被引:1,自引:0,他引:1
The increase in damage due to natural disasters is directly related to the number of people who live and work in hazardous
areas and continuously accumulate assets. Therefore, land use planning authorities have to manage effectively the establishment
and development of settlements in flood-prone areas in order to avoid the further increase of vulnerable assets. Germany faced
major destruction during the flood in August 2002 in the Elbe and Danube catchments, and many changes have been suggested
in the existing German water and planning regulations. This article presents some findings of a “Lessons Learned” study that
was carried out in the aftermath of the flood and discusses the following topics: 1) the establishment of comprehensive hazard
maps and flood protection concepts, 2) the harmonization of regulations of flood protection at the federal level, 3) the communication
of the flood hazard and awareness strategies, and 4) how damage potential can be minimized through measures of area precaution
such as resettlement and risk-adapted land use. Although attempts towards a coordinated and harmonized creation of flood hazard
maps and concepts have been made, there is still no uniform strategy at all planning levels and for all states (Lae
nder) of the Federal Republic of Germany. The development and communication of possible mitigation strategies for “unthinkable
extreme events” beyond the common safety level of a 100-year flood are needed. In order to establish a sustainable and integrated
flood risk management, interdisciplinary and catchment-based approaches are needed. 相似文献

This paper describes some of the insights gained by the authors in the development of an approach for systemic sustainability analysis to arrive at sustainability indicators (SIs) for development. The paper describes the problems of perspective and mindset which such research involves, and the necessity to rethink both the purpose and content of SIs as well as taking into account the perspective of the researcher. The result represents a new perspective on the classification of SIs that serves to highlight one of the central difficulties encountered so far with these tools, namely their limited use in management and the setting of policy. We argue that this is due in large part to the nature of the SI frameworks created to date, even if carried out in a 'participative' mode. The framework itself is representative of a mindset or paradigm of understanding which, when applied as the sole device, we find less than adequate in achieving useful SIs. SIs arising from this mindset tend to be quantitative and explicit (clearly stated and with a defined methodology), while in practice most people's and institutions' use of SIs tends to be more qualitative and implicit ('understood' to apply in vaguer terms, with no defined methodology). These two paradigms or mindsets are represented here as the reductionist and the conversational : the first is characterised by quantitative and explicit indicators (or QNE* indicators); and the second is characterised by qualitative and implicit indicators (QLI* indicators). We suggest that what is required is far more research on the evolution and use of QLI* SIs (and the mindset which is necessary to develop them), in order to best appreciate how they can be hybridised with the QNE* group. The result may be termed 'multiple perspective' SIs. Este documento describe algunas de las ideas obtenidas por los autores en el desarrollo de un acercamiento por análisis de sostenimiento sistemático para llegar a los indicadores de sostenimiento (SIs) por desarrollo. El documento describe los problemas de perspectiva y patrones que dicha investigación involucra, y la necesidad de repensar tanto en el propósito como en el contenido de los SIs así como tambien toma en cuenta la perspectiva del investigador. El resultado representa una nueva perspectiva en la clasificación del los SIs la cual sirve para resaltar una de las dificultades centrales encontradas hasta ahora con estas herramientas; especificamente su limitado uso en el manejo y establecimiento de políticas. Nosotros argumentamos que ésto se debe en gran parte a la naturaleza de las estructuras de los SIs creadas hasta la fecha, incluso si se lleva a cabo en un modo 'participativo'. La estructura por si misma es representativa de un patron o paradigma de entendimiento el cual cuando es aplicado al esquema único encontramos menos adecuado alcanzar SIs útiles. Los SIs que surgen de este patrón tienden a ser cuantitativos y explícitos (claramente señalados y con una metodología definida), mientras que en la practica el uso de los SIs por parte de la mayoria de la personas e instituciones tiende a ser mas cualitativo e implicito ('entendido' a aplicar en terminos mas vagos, con metodología mas definida). Estos dos paradigmas o patrones son representados aquí como el reduccionista y el coloquial — uno es caracterizado por indicadores cuantitativos y explícitos (o indicadores QNE*), el otro por indicadores cualitativos e implícitos (QLI*) respectivamente. Nosotros sugerimos que lo que se requiere es mucha mas investigación en la evolución y uso de SIs de QLI* (y el patrón que es necesario para desarollarlo), para apreciar mejor como ellos pueden ser mezclados con el grupo de QNE*. El resultado puede ser denominado indicadores de sostenimiento de perspectiva multiple. 相似文献

This paper evaluates the adoption of standards as proof of and an incentive for sound environmental practice in business and industry. The paper outlines the origins of environmental management and the development of the first environmental management standard BS 7750. The background to quality management is outlined to provide a context for these developments. The paper then goes on to examine the likely success of BS 7750 in actually improving the environmental performance of organizations in the light of experience in the field of quality. Finally, alternative approaches are looked at as ways of achieving environmental improvement. 相似文献

Local environmental assessment (EA), mandated by five US states, has introduced complex management issues for practitioners and policy makers. Based on a review of statutes, case law, and prior EA evaluations,this paper outlines three key issue areas for local EA: linking comprehensive planning and EA; making the threshold determination process more certain; and balancing mitigation with public participation. The paper argues that all the issues reflect a central tension in environmentalassessment between procedural consistency and the need for contingent responses to conditions that differ among the projects to be reviewed. 相似文献

Local Agenda 21 (LA 21) may be regarded as one of the most enduring and possibly most effective outcomes of the 1992 Rio de Janeiro ‘Earth Summit’. In Europe alone, approximately 4000 cities, municipalities at regional and local level, and regional authorities are now engaged in a LA 21 process of some kind. This paper reports on the main findings of the recent Local Authorities' Self-Assessment of Local Agenda 21 (LASALA) project, which conducted a Europe-wide research programme into the European LA 21 initiative. The research demonstrates the significant levels of commit ment to the LA 21 process amongst European local government, and some notable achievements in sustainable development policies within a very short space of time. Although there is still a long way to go, the LASALA research indicates that LA 21 is an effective policy vehicle for encouraging and supporting sustainable development initiatives at the local level in Europe. 相似文献

Multinational,Freshwater Biomonitoring Programs in the Developing World: Lessons Learned from African and Southeast Asian River Surveys 总被引:1,自引:1,他引:1
Resh VH 《Environmental management》2007,39(5):737-748
Biomonitoring programs are widely used in developed countries. They also offer many advantages in assessing ecological consequences
of perturbations in developing countries, including reducing the equipment-operation, maintenance, and training costs associated
with physicochemical monitoring. Three case histories of river biomonitoring using freshwater organisms (fish, benthic macroinvertebrates,
diatoms, zooplankton) are described that involve (1) documentation of environmental effects from long-term, large-scale applications
of insecticides to control insect-vectors of river blindness (onchocerciasis) in 11 West African countries; (2) water quality
assessments and restoration planning in and around national parks in three East African countries; and (3) evaluation of overall
ecological health of the Lower Mekong River in four Southeast Asian countries. As in developed countries, benthic macroinvertebrates
are the organisms most widely used in biomonitoring in developing countries. Conflicting opinions of system resilience and
whether expected changes are within natural variation may result in differences in underlying hypotheses proposed, study designs
implemented, and study execution; each may lead to uncorrectable bias. Direct transfers of approaches used from developed
to developing countries are often appropriate; however, techniques dependent on pollution-tolerance values are often region
specific and not transferable. Typically expressed concerns about applications of biomonitoring in developing countries include
poor coordination among agencies; lack of legislation, identification keys, and trained personnel; and incomplete information
on how tropical rivers function. Problems are real but solvable, as evident from accomplishments in several multicountry programs
in developing countries. Developed countries requiring coordinated monitoring of international rivers may benefit from examining
successful programs under way in developing countries. 相似文献

Abstract: Residential water demand is a function of several factors, some of which are within the control of water utilities (e.g., price, water restrictions, rebate programs) and some of which are not (e.g., climate and weather, demographic characteristics). In this study of Aurora, Colorado, factors influencing residential water demand are reviewed during a turbulent drought period (2000‐2005). Findings expand the understanding of residential demand in at least three salient ways: first, by documenting that pricing and outdoor water restriction policies interact with each other ensuring that total water savings are not additive of each program operating independently; second, by showing that the effectiveness of pricing and restrictions policies varies among different classes of customers (i.e., low, middle, and high volume water users) and between predrought and drought periods; and third, in demonstrating that real‐time information about consumptive use (via the Water Smart Reader) helps customers reach water‐use targets. 相似文献

Management of microbial contamination in storm runoff from California coastal dairy pastures 总被引:1,自引:0,他引:1

A survey of storm runoff fecal coliform bacteria (FCB) from working farm and ranch pastures is presented in conjunction with a survey of FCB in manure management systems (MMS). The cross-sectional survey of pasture runoff was conducted on 34 pastures on five different dairies over 2 yr under varying conditions of precipitation, slope, manure management, and use of conservation practices such as vegetative filter strips. The MMS cross-sectional survey consisted of samples collected during 1 yr on nine different dairies from six loafing barns, nine primary lagoons, 12 secondary lagoons, and six irrigation sample points. Pasture runoff samples were additionally analyzed for Cryptosporidium sp. and Giardia duodenalis, whereby detectable concentrations occurred sporadically at higher FCB concentrations resulting in poor correlations with FCB. Prevalence of both parasites was lower relative to high-use areas studied simultaneously on these same farms. Application of manure to pastures more than 2 wk in advance of storm-associated runoff was related to a > or =80% reduction in FCB concentration and load compared to applications within 2 wk before a runoff event. For every 10 m of buffer length, a 24% reduction in FCB concentration was documented. A one-half (75%), one (90%), and two (99%) log10 reduction in manure FCB concentration was observed for manure holding times in MMS of approximately 20, 66, and 133 d, respectively. These results suggest that there are several management and conservation practices for working farms that may result in reduced FCB fluxes from agricultural operations. 相似文献

As collaborative groups gain popularity as an alternative means for addressing conflict over management of public lands, the
need for methods to evaluate their effectiveness in achieving ecological and social goals increases. However, frameworks that
examine both effectiveness of the collaborative process and its outcomes are poorly developed or altogether lacking. This
paper presents and evaluates the utility of the holistic ecosystem health indicator (HEHI), a framework that integrates multiple
ecological and socioeconomic criteria to evaluate management effectiveness of collaborative processes. Through the development
and application of the HEHI to a collaborative in northern Arizona, the Diablo Trust, we present the opportunities and challenges
in using this framework to evaluate the ecological and social outcomes of collaborative adaptive management. Baseline results
from the first application of the HEHI are presented as an illustration of its potential as a co-adaptive management tool.
We discuss lessons learned from the process of selecting indicators and potential issues to their long-term implementation.
Finally, we provide recommendations for applying this framework to monitoring and adaptive management in the context of collaborative
management. 相似文献

By committing to green procurement, the UK government has taken a key initial step towards sustainable development. But can this be put into practice? This policy analysis explores the background to green procurement in English local government through desk research and data collection, including interviews with five local authorities. It finds that green procurement has been encouraged through legislation, providing information and dismantling barriers, but momentum was lost following the Gershon review. Implementation of the new action plan would ensure green procurement becomes embedded within government procurement. New information to link up green procurement with organisational goals would also expand the horizons of green procurement. 相似文献

Success Factors for Community-Based Natural Resource Management (CBNRM): Lessons from Kenya and Australia 总被引:1,自引:0,他引:1
Recent concerns over a crisis of identity and legitimacy in community-based natural resource management (CBNRM) have emerged following several decades of documented failure. A substantial literature has developed on the reasons for failure in CBNRM. In this paper, we complement this literature by considering these factors in relation to two successful CBNRM case studies. These cases have distinct differences, one focusing on the conservation of hirola in Kenya on community-held trust land and the other focusing on remnant vegetation conservation from grazing pressure on privately held farm land in Australia. What these cases have in common is that both CBNRM projects were initiated by local communities with strong attachments to their local environments. The projects both represent genuine community initiatives, closely aligned to the original aims of CBNRM. The intrinsically high level of “ownership” held by local residents has proven effective in surviving many challenges which have affected other CBNRM projects: from impacts on local livelihoods to complex governance arrangements involving non-government organizations and research organizations. The cases provide some signs of hope among broader signs of crisis in CBNRM practice. 相似文献

200 years of sustainability in forestry: Lessons from history 总被引:4,自引:0,他引:4
K. Freerk Wiersum 《Environmental management》1995,19(3):321-329
Since the end of the 1980s the concept of sustainable development has gained general acceptance, but much uncertainty still
exists on how to operationalize this concept. In forestry the concept of sustainability has been an accepted principle since
the 18th century. The experiences with its application in forestry may contribute towards obtaining a better insight into
the implications and operational significance of the concept of sustainability. This article describes the history of sustainability
in forestry, including the various social values on which its interpretation has been based. The original principle of sustained
yield has gradually been broadened to a more inclusive principle of sustainable forest management. The dynamics in social
valuation of forest resources resulted in various attempts at practical operationalization of the principle. Notwithstanding
200 years of efforts to operationalize the concept of sustainability, its exact application in forestry remains troublesome.
Three lessons are drawn: (1) the need to recognize the different nature of ecological limits and social dynamics, (2) the
role of dynamic social values with respect to forest resources, and (3) the significance of operational experiences in trying
to attain sustainability within a concrete context. 相似文献

Effective river management requires integration of biophysical and human dimensions of the ecosystem, which in turn involves the development of new forms of decision-making processes and institutional frameworks. In New South Wales, institutional changes to river management have been formalized in the Water Management Act 2000. This paper presents the findings of a case study that investigated decision-making processes in the establishment of environmental flow regimes for the Lachlan River in western New South Wales. The study was based on document analysis, observation and interviews with members and support staff of a stakeholder-based river management committee. The findings of the study highlight social capital, adaptive management and consensus decision making as key components in establishing environmental flow regimes as part of a participatory approach to river management. 相似文献
