Tribal communities,the forests,the fisher folk and the river: whither water justice?

Excessive exploitation of and skewed access to dwindling water resources raise serious water justice concerns. Environmental justice movements and related literature have raised critical questions regarding the unequal distribution of the costs and benefits of a development paradigm that is founded on excessive exploitation and appropriation of natural resources. This paper explores the growing relevance of a water justice framework that addresses both the social and ecological aspects of water use and appropriation, with reference to a four-decade long water conflict over the Chaliyar River in Kerala, South India. It highlights how ecosystem degradation and denial of justice go hand in hand. The paper argues that the framing and articulation of the conflict in a partisan manner led to the glossing over of certain critical features, thus preventing a full view of water injustices. It also failed to inform subsequent policies and practices in this regard.     

Vegetation and outdoor recess time at elementary schools: What are the connections?

Empirical and anecdotal evidence suggests that landscapes with more vegetation have a positive impact on children's focus, attention, and cognitive development. In school, children are able to regain focus, suppress impulses, and pay attention in class longer after exposure to natural settings. Because children spend much of their time in school, the amount and types of vegetation on school grounds may influence their development. Public elementary schools in the Commonwealth of Virginia (N = 988) were surveyed to examine correlations between school ground vegetation and outside recess. The number of trees on school grounds, the size of the school grounds, and the presence of sports fields were modestly correlated with greater outside recess time. These correlations support common sense because sports fields facilitate supervised play and larger school grounds provide space for sports fields and playgrounds and additional opportunities for free play. More trees on school grounds provide a welcoming environment for students and teachers, and encourage outside play. These results may help school personnel design and maintain school grounds that increase outdoor recess time.

The good,the bad,and the statutory: are statutory or non-statutory natural resource management plans higher in quality?

Numerous governments around the world have adopted statutory mandates on plan content based on the assumption that they lead to greater consistency and higher quality of plans. While a number of studies have examined the relationship between mandates to develop plans and plan quality, there has been limited study of the influence of state mandates for plan content on plan quality in a regional natural resource management (NRM) planning context. This paper explores the relationship between the quality of regional NRM plans between statutory and non-statutory NRM regions in New South Wales and Queensland, Australia. An analysis of 22 regional NRM plans indicates that there is no evidence of a relationship between plan quality and the presence of statutory mandates for regional NRM plans in New South Wales and Queensland. However, the paper identifies and discusses several other factors with unexpected relationships with an impact on the quality of NRM plans in New South Wales and Queensland, Australia.     

Surface water quality and its control in a river with intensive human impacts–a case study of the Xiangjiang River,China

Surface water quality and its natural and anthropogenic controls in the Xiangjiang River were investigated using multivariate statistical approaches and a comprehensive observation dataset collected from 2004 to 2008. Cluster analysis (CA) grouped the 15 different sampling stations into five clusters with similar hydrochemistry characteristics and pollution levels. Four principal components (PCs), nutrients, heavy metals, natural components, and organic components, were extracted from the entire dataset. Comparison of the different regional characteristics of these four PCs revealed a decreasing trend for heavy metals and an increasing trend for organic factor on an annual scale, and the seasonal trend was only observed for natural factor. We also conducted analysis of variance (ANOVA) in combination with principal component analysis (PCA) to quantify the relative contribution of spatial and temporal variations to each of the four PCs. The results revealed that 62% of the contributions from the spatial sites were responsible for variations in heavy metals, while 83% of the contributions from the sampling time were responsible for natural variations observed. However, no significant spatial or temporal contributions were found to be responsible for the nutrient and organic variations. Finally, some suggestions regarding water management were put forward based on the current status and future trends of surface water quality in the Xiangjiang River.     

Re‐thinking water scarcity: Can science and technology solve the global water crisis?

This paper provides examples from the last fifty years of scientific and technological innovations that provide relatively easy, quick and affordable means of addressing key water management issues. Scientific knowledge and technological innovation can help open up previously closed decision‐making systems. Four of these tools are discussed in this paper: a) the opportunities afforded by virtual water trade; b) the silent revolution for beneficial use of groundwater; c) salt water desalination; and finally, d) the use of remote sensing and geographic information systems (GIS). Together these advances are changing the options available to address water and food security that have been predominant for centuries in the minds of most water decision‐makers.     

What drives large South African corporations to invest in sub‐Saharan Africa? CEO's perspectives and implications for FDI policies

Foreign direct investment (FDI) flowing into Africa is highly diverse in terms of the origin of the investors, size of the firms, and the sectors of activity. The motivations and factors driving firms' decisions to invest in Africa are equally diverse. A direct survey of senior management in South African firms that are operating in sub-Saharan Africa reveals that the drivers of foreign investment as well as the risks and the strategies to overcome them differ markedly between sectors. A further finding is that there is a limited pool of FDI promotion policies and incentives that governments can institute that are effective in impacting South African corporations' investment decisions. As a consequence, broad-based FDI promotion policies aimed at attracting FDI across all investor groups are likely to have limited impact in attracting FDI from any particular investor group, or in attracting any FDI from multinational companies similar to the South African companies studied here. Such broad based policies probably need to be complemented with policies targeting those specific firms or sectors which countries hope to attract.     

Evaluating the multiple benefits of marine water quality improvements: how important are health risk reductions?

Marine water pollution affects many recreational sites around the world. It has impacts not only on recreational activities but also on health risks for those who come into direct contact with the water. Few economic studies have explicitly considered the health risks of bathing in polluted marine waters and none have attempted to separate health benefits from other benefits of marine water quality improvements. This paper uses stated preference techniques to separately evaluate the multiple benefits of improving the quality of marine recreational waters at the Estoril Coast in Portugal. The results indicate that health risk reductions are only a small fraction of the total social benefits of water quality improvements.     

Evaluating the efficacy of adaptive management approaches: Is there a formula for success?

Within the field of natural-resources management, the application of adaptive management is appropriate for complex problems high in uncertainty. Adaptive management is becoming an increasingly popular management-decision tool within the scientific community and has developed into two primary schools of thought: the Resilience-Experimentalist School (with high emphasis on stakeholder involvement, resilience, and highly complex models) and the Decision-Theoretic School (which results in relatively simple models through emphasizing stakeholder involvement for identifying management objectives). Because of these differences, adaptive management plans implemented under each of these schools may yield varying levels of success. We evaluated peer-reviewed literature focused on incorporation of adaptive management to identify components of successful adaptive management plans. Our evaluation included adaptive management elements such as stakeholder involvement, definitions of management objectives and actions, use and complexity of predictive models, and the sequence in which these elements were applied. We also defined a scale of degrees of success to make comparisons between the two adaptive management schools of thought. Our results include the relationship between the adaptive management process documented in the reviewed literature and our defined continuum of successful outcomes. Our data suggest an increase in the number of published articles with substantive discussion of adaptive management from 2000 to 2009 at a mean rate of annual change of 0.92 (r2 = 0.56). Additionally, our examination of data for temporal patterns related to each school resulted in an increase in acknowledgement of the Decision-Theoretic School of thought at a mean annual rate of change of 0.02 (r2 = 0.6679) and a stable acknowledgement for the Resilience-Experimentalist School of thought (r2 = 0.0042; slope = 0.0013). Identifying the elements of successful adaptive management will be advantageous to natural-resources managers considering adaptive management as a decision tool.     

Environmental management system vs green specifications: How do they complement each other in the construction industry?

Environmental Management System (EMS) has been one of the important tools for sustainable construction for around two decades. However, many issues concerning sustainable development have not been properly addressed, and there is a need for the introduction of green specifications to advance green performance in construction through contract management. This paper defines green specifications, identifies the reasons for adopting green specifications and highlights the environmental issues that may not be addressed by solely adopting EMS. It also presents the results of a recent survey of practitioners concerning their opinions towards green specifications and possible impacts arising from their adoption. From the results of the survey, a framework for developing green specifications is deemed valuable for the cities striving for sustainability. Interestingly, the level of acceptable changes brought about by green specifications as perceived by different industry stakeholders is found to be unrelated to whether they were from organizations implementing EMS or not.     

Come hybrid or high water: Making the case for a Green–Gray approach toward resilient urban stormwater management

120 years or more of unsustainable urban development has damaged the natural environment and disrupted essential ways to stabilize water body overflow and even mitigate pluvial flooding. In light of catastrophic flooding that has occurred globally, a renewed commitment to transforming built surfaces and incorporating more green infrastructures (GIs) has emerged. In fact, one could argue that an overcommitment to GI is being touted in the literature, but largely disconnected from more real-world possibilities, considering all things. In this commentary, we make the case that as cities transition from development patterns of the past and even considering climate-induced storm characteristics of the future, a hybridized solution (e.g., Green–Gray) should be considered. Smaller approaches to urban greening have been implemented in areas that need larger-scale restorations, thus proving to be insufficient. Likewise, the uncertainty surrounding rainfall and storm events has forced us to be more strategically balanced in our efforts to achieve resilience in our stormwater infrastructure. Hybridized solutions that include a diverse set of systems, anchored in local conditions, position us best for effective urban stormwater management. In the absence of such solutions, runoff volumes will continue to rise, flooding will prevail, and disenfranchised communities will remain disproportionately impacted by these impacts of urbanization.     

Collaboration between design and waste management: Can it help close the material loop?

In order to explore the current relationship between industrial design and waste management (WM), a semi-structured interview study was carried out with 25 professionals from WM and designers that have worked with waste. The main aim was to learn about the collaborative work between these two areas and to investigate whether collaboration could help to incorporate material resources into production. The study reveals that designers and WM professionals regard the relation between disciplines in different ways, being more or less centered in their own disciplines. The designers interviewed, however tend to have a wider impression of this relation. This, together with the lack of understanding of the other's role and a fundamental scale difference when dealing with material flows were identified as the main barriers to better and more frequent collaboration. Even though some examples of collaborative work were found, they were not significant enough to have any noticeable effect on the WM system. In order to facilitate future collaboration, the contribution of the presented work is to identify areas for collaboration and suggest initial solutions for overcoming the barriers encountered to help to close the material loop.     

Creating and sustaining community capacity for ecosystem-based management: Is local government the key?

Recently, collaborative approaches to natural resource management have been widely promoted as ways to broaden participation and community involvement in furthering the goals of ecosystem management. The language of collaboration has even been incorporated into controversial legislation, such as the US Healthy Forests Restoration Act of 2003. This research examines collaboration and sharing management responsibility for federal public land with local communities through a case study of the Ashland Municipal Watershed in southern Oregon. A policy sciences approach is used to analyze community participation and institutional relationships between the US Department of Agriculture, Forest Service, and local city government in the planning processes of five land management actions occurring over a 7-year period. The knowledge gained from examining differing approaches to planning and decision making in the Ashland watershed is used to suggest future planning processes to develop and sustain the community capacity necessary to support implementation of community-based ecosystem management.     

Can area managers connect policy and tenants? Implementation and diffusion of a new waste management system in Linköping,Sweden

Recycling and reducing household waste are political goals internationally, nationally and locally. In Sweden, households in apartment buildings seem to sort their waste to a lesser extent than households in single-family houses. This paper analyses the challenges of the diffusion of a new waste management system in apartment buildings, and focuses on a municipal housing company and the actions of its area managers. It is argued that area managers can be regarded as street-level bureaucrats who act as ‘collectors’ of tenants’ everyday practices in the studied implementation process. The study is based on interviews, document analysis and observations.     

An assessment of Spain's Programa AGUA and its implications for sustainable water management in the province of Almería, southeast Spain

Spain's Programa AGUA was proposed in 2004 as a replacement for the Spanish National Hydrological Plan and represented a fundamental policy shift in national water management from large inter-basin water transfers to a commitment to desalination. Twenty-one desalination facilities are planned for six provinces on the Spanish Mediterranean coast to supplement their water needs. These include the province of Almería that for the last 30 years has endured a net water abstraction overdraft leading to serious reservoir depletion and groundwater imbalances. Rising water use is a result of increasing demand to support irrigated agriculture (e.g. greenhouse horticulture) and for domestic needs (e.g. rapid urban growth and tourism development), which has led observers to question Almería's long-term water sustainability. Desalinated water alone is unlikely to be sufficient to make up these water deficits and water-users will have to accept a move to full-price water recovery by 2010 under the European Union (EU) Water Framework Directive of which Spain is a signatory. Anticipated water efficiencies resulting from higher water tariffs, increasing water reuse and water infrastructure improvements (including inter-basin transfers), in conjunction with increasing use of desalinated water, are expected to address the province's current water overdraft. However, Almería will need to balance its planned initiatives against long-term estimates of projected agricultural and domestic development and the environmental consequences of adopting a desalination-supported water future.     

Adapting a holistic approach to flood management in the Hawkesbury–Nepean region: complexities and perceptions of the agencies involved

This paper looks into the complexity of managing flood risks in the Hawkesbury–Nepean catchment, Australia. Several aspects are explored: (1) the complexities created by the way different agencies are involved in assessing flood risks; (2) different perceptions on acceptable flood risk level; (3) community engagement in defining acceptable flood risk level; (4) views on a holistic flood risk management plan; and (5) challenges of a centralised information system. This study concludes that the complexity of managing a large catchment is exacerbated by the difference in the way professionals perceive the problem. This has led to (1) different standards for acceptable risks; (2) inconsistent attempt to set up a regional-scale flood management plan beyond the jurisdictional boundaries; (3) absence of a regional-scale agency with licence to share and update information; and (d) lack of forums for dialogue with insurance companies to ensure an integrated approach to flood management.     

Developing decision support systems for integrated coastal management in the tropics: is the ICM decision-making environment too complex for the development of a useable and useful DSS?

Integrated coastal management in the tropics requires the conservation of vulnerable and diverse ecosystems such as coral reefs and mangroves as well as the management of land and marine-based human activities. Decision-making for integrated coastal management involves multiple decision-makers and multiple stakeholders often with conflicting needs and interests. Decision support systems can be developed to improve our understanding of the inter-relationships between the natural and socio-economic variables and hence result in improved decision-making. The question is whether this decision making environment is actually too complex for the development of useful and useable decision support systems. This paper describes the components of the decision making environment and the components of a decision support system. It also explores the various techniques available to deal with different modelling needs, the constraints of inadequate data and the multi-objective decision making environment. In addition, different techniques of developing decision support systems can play important roles within integrated coastal management. Three coastal decision support systems are evaluated in terms of their design and role in integrated coastal management and are used to evaluate the potential to develop decision support systems for integrated coastal management.     

Abatement cost curves: a viable management tool for enabling the achievement of win-win waste reduction strategies?

Environmental regulation of industrial activity is generally believed to have a negative impact on the industry. Recent literature has suggested, however, that reducing industrial waste outputs can, in some circumstances, result in a 'win-win', or at least 'win-draw', scenario for industry and the environment. The viability of using the abatement cost curve method as a management tool to enable the achievement of a 'win-win' state is investigated here. Copper pollution in the Humber Estuary is used as a case-study, and the abatement cost curve methodology proves to be a valuable tool in identifying barriers to achieving the win-win state, and also in providing future direction for the waste management strategy. Abatement cost curves are concluded to be powerful management tools which greatly improve the transparency of waste reduction information.
