Constructing Water Shortages on a Huge River: The Case of Shanghai

Shanghai is located on the world's third largest river (by volume). Yet it faces the risk of shortages of drinking water. Many decisions and environmental characteristics have contributed to this threat. First, Shanghai has become dependent on water brought into the municipality by rivers. Second, it has become increasingly reliant on water from the Changjiang (Yangzi River), principally in order to control the levels of pollution in the water that enters its treatment plants. Third, for reasons associated with inter‐provincial administrative arrangements, the city's water intakes are located within the municipality, within the estuary zone and subject to tidal intrusions of salt water. Fourth, at high tide and when the Changjiang's discharge is low, salt intrudes far into the estuary, beyond the current water intakes. If sea levels rise, these intrusions will become more pronounced. Fifth, large‐scale central government infrastructure projects (such as dams and the South‐North Transfer) are altering the hydrological characteristics of the river. Such projects raise the probability of salt water intrusions into the water intake zone. The Shanghai and central governments have thus made a series of decisions that, taken together, have led the municipality to rely on a source of drinking water that is increasingly unreliable and subject to the risk of shortages due to salt water intrusions. Why these decisions have been made – independently – is an important problem for those who would understand the provision of water for cities and the practical efficacy of Chinese governance systems.     

The Key Role of Water Resources Management in Ecological Restoration in Western China

The interactions of nature and society are intimately reflected in the degradation of the vast, yet diverse, landscapes and ecosystems of arid western China. The development of agriculture, especially irrigation, has altered rivers, soils and ecosystems so much that major ecological rehabilitation and restoration efforts have been needed since 1950. The catchments of the Tarim River in southern Xinjiang (the Tarim Basin) and of the Black River (Hei He) in Gansu Province and western Inner Mongolia provide examples of the benefits, difficulties and conflicts involved in dryland water management. In the early stages of the human development of these catchments, agriculture depending on irrigation using water from these inland rivers was encouraged. The over‐exploitation of these water resources led to such ecological problems as desiccation of lakes, drying out of rivers, degradation of soils and vegetation and lowering of groundwater levels, with consequent environmental and economic impacts. Since 1990 several high‐cost, national projects to re‐establish ecosystems have been initiated. Water is now released from dams in the headwaters of the rivers in order to restore water flows to the dried out lake basins. Such schemes have inevitably led to social problems and difficulties for the people who depended on the water from the dams for local irrigation. The contrasts in adjustments and attitudes over the use of water for agriculture and other economic activities, as opposed to schemes of restoration of ecosystems and ecological engineering, stem largely from two issues; inconsistent provision of information from the scientific community, and differing ideologies, namely environmental protection versus economic development.     

Response to Wet Season Rainfall of an Alluvial Aquifer System in the Lower Herbert Floodplain,Queensland, Australia

Australia is one of the world's largest exporters of raw sugar. The lower Herbert River floodplain, one of the four main cane growing areas in Queensland, is subject to extremes of rainfall. Some areas are prone to waterlogging, which can lead to reductions in cane and sugar yields. This paper examines the risk of waterlogging and the role of surface drains in the Ripple Creek area, a subcatchment of the lower Herbert River floodplain. Following above‐average rains at the onset of this study, a perched water table developed and remained for the duration of the 19 month study. The responses of the perched watertable and a deeper semi‐confined aquifer following rainfall are examined. The rapid response of the perched water table following rainfall is attributed to the shallow depth of the water table, with soil properties exerting a dominant influence on hydrograph response. In the second year of the study, after above‐average rainfall, the water table of the deeper aquifer was on average 1 m higher than during the former months of the study. This trend, however, did not occur in the perched water table, and this is attributed to the efficiency of the surface drainage network.

Voluntary Environmental Programs in the Public Sector: Evaluating an Urban Water Conservation Program in California

Solving conflictual environmental policy problems is increasingly falling under the purview of local governments and public agencies. Nonregulatory approaches, such as the development of voluntary environmental programs (VEPs), could offer a useful policy alternative as they often have greater political traction and flexibility. However, there has been little work examining the use of VEPs in the public sector. This article uses a new dataset from California to examine how political institutions affect decisions by local governments and public agencies to participate in a voluntary urban water conservation program and whether this program has improved the water conservation performance of its members. The results show that special district governments, private utilities, and water suppliers dependent on purchased water are more likely to participate in the program and to join early. However, urban water agencies that have joined the program have not reduced their per capita water use more than those that have not. These results underscore the influence of political institutions in public‐sector decision making and demonstrate that, as in the private sector, commitment to a VEP by local government and public agencies does not guarantee implementation or environmental improvements. While voluntary programs offer political and administrative advantages, in order for VEPs in the public sector to be effective they must be accompanied and supported by credible enforcement mechanisms, performance standards, and rigorous monitoring programs.     

Tuvalu and Climate Change: Constructions of Environmental Displacement in The Sydney Morning Herald

Tuvalu, a place whose image in the ‘West’ is as a small island state, insignificant and remote on the world stage, is becoming remarkably prominent in connection with the contemporary issue of climate change‐related sea‐level rise. My aim in this paper is to advance understanding of the linkages between climate change and island places, by exploring the discursive negotiation of the identity of geographically distant islands and island peoples in the Australian news media. Specifically, I use discourse analytic methods to critically explore how, and to what effects, various representations of the Tuvaluan islands and people in an Australian broadsheet, the Sydney Morning Herald, emphasize difference between Australia and Tuvalu. My hypothesis is that implicating climate change in the identity of people and place can constitute Tuvaluans as .tragic victims. of environmental displacement, marginalizing discourses of adaptation for Tuvaluans and other inhabitants of low‐lying islands, and silencing alternative constructions of Tuvaluan identity that could emphasize resilience and resourcefulness. By drawing attention to the problematic ways that island identities are constituted in climate change discourse in the news media, I advocate a more critical approach to the production and consumption of representations of climate change.     

Towards a Culturally Sustainable Environmental Impact Assessment: The Protection of Ainu Cultural Heritage in the Saru River Cultural Impact Assessment,Japan

Culturally sustainable environmental impact assessment (EIA) requires consideration of the impact of development on local people's cultural activities, including holding ceremonies, collecting resources, and learning skills, which are fundamental essences of Indigenous rights. While culturally sustainable EIA has become a common practice when a development project involves an Indigenous community, it is still argued that Indigenous cultural heritage is not adequately protected. This is due to the fact that Indigenous people do not always keep power in the post‐approval stage of EIA, or the lack of practical measures to minimise the impact of development projects on Indigenous cultural heritage and to enhance the possibility of reaching a consensus among stakeholders. The Cultural Impact Assessment of the Saru River Region in Japan was the first investigation of a site to preserve an ethnic minority culture, with regard to a dam construction. In the second phase of the assessment project, research staff members, some of whom are of Ainu ethnicity, suggested alternative ceremony sites and conducted experimental transplants to protect the local cultural activities. The long‐term investigation by research staff, in fact, influenced the direction of the dam construction. The developer agreed not to proceed with the construction until measures were taken to minimise the impact on cultural activities that would satisfy residents in the construction area. While still early to conclude that Indigenous participation in this assessment project has been successful, Indigenous participation has clearly enhanced the possibility of reaching a consensus. The project should be considered with other published EIA reports, in demonstrating a return from investing in EIA with Indigenous participation, with a practical means for realising Indigenous rights.     

The Symbolic Politics of Belonging and Community in Peri‐urban Environmental Disputes: the Traveston Crossing Dam in Queensland,Australia

This paper examines a recent dispute generated by the Queensland State Government proposal to build the Traveston Crossing Dam on the Mary River in southeast Queensland, Australia. It is particularly concerned with the ways in which interrelated issues of belonging, community identity, and social diversity were negotiated during the anti‐dam campaign. As an unusual alliance of farmers, environmentalists, urban retirees, some Aboriginal people and others, it takes a view of the anti‐Traveston Crossing Dam campaign as a fluid network of people and approaches the notion of community identity as the symbolic construction of similarity. Locally specific, the paper describes pertinent aspects of community politics in the context of rural socioeconomic change, and the mobilisation of heritage. With regard to local senses of belonging, it also discusses the involvement of Aboriginal people during the campaign. More broadly then, this paper attempts to make an ethnographic contribution to the study of environmental disputes and the politics of alliance in peri‐urban areas of settler‐descendant societies such as Australia.     

Experiencing Waterholes in an Arid Environment,with Particular Reference to the Lake Eyre Basin,Australia: a Review

The distribution and permanence of waterholes have dictated human activity and settlement patterns in the arid zone for millennia. At a fundamental level, waterholes are vital to survival in a harsh climate. The recreational value and use of waterholes are widely recognised; however, the less tangible aspects of ‘waterhole experience’ have received scant attention. This review, written whilst compiling an inventory of permanent waterbodies across the Lake Eyre Basin of Queensland and South Australia, aimed to provide a deeper understanding of the interaction of humans with water in an arid land, primarily from a settler perspective. A large body of literature pertaining to waterholes was reviewed, including Aboriginal histories, explorer journals, accounts of early settlers, and numerous fictional and factual accounts of life in inland Australia. It becomes apparent that human appreciation of arid-zone waterholes runs deeper than the survival imperative, and can be enriched by considering landscape aesthetics and psychology. This attraction has spawned a rich mythology centred on waterholes – permanent features in an otherwise harsh and variable environment.     

Skiing Less Often in a Warmer World: Attitudes of Tourists to Climate Change in an Australian Ski Resort

Climate change will affect tourism destinations that are dependent on natural resources, such as snow. Currently there is limited research into attitudes, intentions and actual visitation patterns of skiers in response to reduced snow cover. Therefore the awareness of, and attitudes towards, climate change of 351 ski tourists were assessed in the largest ski resort in Australia in 2007, repeating a survey conducted in 1996. Ninety percent of skiers in 2007 would ski less often in Australian resorts if the next five years had low natural snow, up from 75% of skiers surveyed in 1996: 69% would ski less often, 5% would give up and 16% would ski at the same levels but overseas. Nearly all skiers thought that climate change would affect the ski industry (87% compared with 78% in 1996), and that this would occur sooner than in the 1996 survey. Visitation in a poor snow year (2006, +0.85°C average annual temperature, 54% less natural snow) was −13.6% of the long-term average, indicating poor natural snow resulted in decreased visitation, despite extensive use of snow making. The implications of changes in climate conditions and tourist attitudes for Australian ski resorts are assessed including for snow making and summer tourism.     

The Historical Geographies of Showing Livestock: a Case Study of the Perth Royal Show,Western Australia

This paper examines changes in the entries of livestock to competitions at the Perth Royal Show in the course of the twentieth century. It identifies trends in the showing of animals at the Show and explains these with reference to the wider geographies of state and national agricultural change in Western Australia (WA). In doing so, it provides a longitudinal perspective on the socioeconomic contexts of farming in WA and identifies some of the key cultural and economic drivers that have influenced livestock farming in that locality. In turn, these findings contribute to wider understandings of the global countryside and of the imagined ruralities that exist within and beyond the spaces of showgrounds.

By‐Elections and Political Change in a Local Context: The Case of the 1973 Dundee East By‐Election and the SNP

With their unpredictability and occurrence in between nationwide elections, by‐elections have attracted a degree of scholarly interest. However, this has focused almost exclusively on how the contests have affected, or failed to affect, the direction of national politics. This article seeks to, instead, explore their influence upon the locality in which they are fought. It will achieve this through an analysis of the 1973 Dundee East by‐election and its consequences for the development of the local Scottish National Party (SNP). Prior to the by‐election, the party had not been particularly strong in Dundee. Yet the contest provided a setting in which it was able to transform itself into one of the most effective Nationalist organisations in Scotland, capable of cementing an SNP MP in the constituency from 1974 until 1987, holding firm against the collapse in the party's support across the country in the late 1970s and early 1980s. The article will examine the extent to which this resistance to the national swing was facilitated by the legacies of the by‐election and the extent to which its wider footprint contributed towards the development of an enduring party tradition that has persisted for decades.     

Mid‐Holocene Development of Mangrove Communities Featuring Rhizophoraceae and Geomorphic Change in the Richmond River Estuary,New South Wales,Australia

This paper describes the hitherto unreported occurrence of mid‐Holocene mangrove deposits in the Richmond River estuary, southeastern Australia, thereby providing evidence for changes in the distribution and composition of mangrove communities within a subtropical estuarine system during the Holocene. Stratigraphic, radiocarbon and palynological evidence indicates that widespread development of mangrove communities took place in the upstream reaches of the Richmond River estuary during the period 7000 to 6000 years BP. These communities maintained their habitat through substrate aggradation under the conditions of a moderate sea‐level rise, in contrast to other estuaries within the region, which generally experienced the submergence of intertidal substrates. Mangrove species belonging to the family Rhizophoraceae, most likely Bruguiera gymnorrhiza and Rhizophora stylosa, dominated these communities, in strong contrast to contemporary communities, which are dominated by Avicennia marina. Moreover, these mid‐Holocene communities were located a considerable distance upstream of the contemporary occurrences of Rhizophoraceae species within the estuary. The changes in the spatial distribution and composition of mangrove communities parallel the large‐scale evolution of the estuary driven by sea‐level variation. Shallow, buried Pleistocene terraces probably contributed to the regionally unique aggradational response of the mangrove communities and their substrates to a sea‐level rise during mid‐Holocene times.     

Narratives of Community and Change in a Contemporary Rural Setting: The Case of Duaringa,Queensland

Contemporary rural communities are being affected by a range of changes and processes in Australia, including major changes in demographic patterns; the organisation and performance of primary industries; levels of government support for economic and social infrastructure; and wider developments in technology and changing socio‐cultural values. The impact of these processes has been felt unequally and small communities which have had a traditionally close relationship with agricultural industries are particularly challenged. The current paper reports on one such community and provides the opportunity to analyse both the the substance and cultural understandings of such forms of rural change/uncoupling. The paper presents local narratives of community and change in Duaringa, Central Queensland and responds to recent international literature suggesting that the meanings and politics of rural change are as significant as the economic trends that are occurring. The Duaringa narratives demonstrate both the substance and dynamics of expressions of community (and loss). And the paper concludes that these meanings are also influenced by wider processes including consumption‐oriented lifestyles and national interests in South East Asian relations.     

The “Commons” Versus the “Commodity”: Alter‐globalization,Anti‐privatization and the Human Right to Water in the Global South

Abstract: In response to the growth of private sector involvement in water supply management globally, anti‐privatization campaigns for a human right to water have emerged in recent years. Simultaneously, alter‐globalization activists have promoted alternative water governance models through North‐South red‐green alliances between organized labour, environmental groups, women's groups, and indigenous groups. In this paper, I explore these distinct (albeit overlapping) responses to water privatization. I first present a generic conceptual model of market environmentalist reforms, and explore the contribution of this framework to debates over ‘neoliberalizing nature’. This conceptual framework is applied to the case of anti‐privatization activism to elucidate the limitations of the human right to water as a conceptual counterpoint to privatization, and as an activist strategy. In contrast, I argue that alter‐globalization strategies—centred on concepts of the commons—are more conceptually coherent, and also more successful as activist strategies. The paper concludes with a reiteration of the need for greater conceptual precision in our analyses of neoliberalization, for both academics and activists.     

Letting Indigenous People Talk About Their Country: a Case Study of Cross‐Cultural (Mis)communication in an Environmental Management Planning Process

This paper presents a case study, based on the experiences of two senior Aboriginal traditional owners who were engaged in negotiations surrounding the establishment of a Regional Forest Agreement (RFA) in southeast Queensland. This case is notable as an illustration of the capacity of natural resource management planning, through negotiation within a formal process, to extinguish native title. Importantly, the personal experiences of two senior Aboriginal people provide an insight into a situation designed to enhance interactions between government and community, with the overt intention of improving natural resource management. However, the record of this personal experience indicates that the communication was less than satisfactory and that the outcomes, at least in terms of the experiences recorded here, of the individual senior Aboriginal community members, was less than satisfactory. We conclude that, despite best intentions, there is an important lack of provision for community influence or power, including any legal or administrative institutional framework. We also conclude that there are important institutional and social processes of engagement still to be developed, including ways of engaging the community more widely that has conventionally been the case.
