The Qinghai–Tibet Railway: A landmark project and its subsequent environmental challenges

The first part of this paper reviews the environment-friendly techniques implemented when the Qinghai–Tibet Railway was built. They include (1) state-of-the-art techniques to protect the permafrost in the subgrade of the railway embankment; (2) measures to avoid disturbing the species in the Qinghai–Tibet Plateau; (3) efforts to minimize the disturbance of the grassland and wetland; and (4) regulation to ensure the environmental disposal of the construction waste. The second part presents the subsequent environmental challenges which, after the operation of the railway, potentially risk the fragile ecological and environmental system in the plateau. The challenges come from the skyrocketing tourists, expansive natural resource exploitation, the long-term efficiency of permafrost-protected measure, and climatic warming.     

Perceptions of American and Russian environmental scientists of today’s key environmental issues: a comparative analysis

Modern science is global. This is particularly true of environmental science, which has been guided to a considerable extent by international environmental policy. Accordingly, one might expect the standards of scientific research around the globe to have unified over the last 30 years. Yet environmental scientists from different nations and scientific schools have demonstrably dissimilar views on key environmental issues. This is the conclusion we reached after a series of in-depth interviews with prominent American and Russian environmental scientists. The greatest difference was found in the perception of two global issues—stratospheric ozone depletion and climate change.     

Water consumption in Barcelona and its regional environmental imprint: a long-term history (1717–2008)

We present the evolution of urban water withdrawal and consumption of Barcelona from the eighteenth to the twenty-first centuries. The boundaries of the urban system have been set into the limits of the current municipality, adjusting the data of earlier periods to include the estimated consumption in former municipalities aggregated to the city. Different sorts of water flows have been either recorded or estimated from scant and indirect information, such as local groundwater extractions obtained from a hydrological model calibrated with historical data on variations in the water table. The changes experienced in catching infrastructures, the regional ecological imprint of the domestic or industrial water consumed together with the rates of growth in population, economic activity and water intensity have been taken into account as driving forces. The series obtained reveal an overall increase in accessibility to safe freshwater, and a corresponding extension of water terrestrial imprints of Barcelona over the Catalan river basins, up to the peak reached in 1967?C1970 both for per capita and total water withdrawn. The subsequent downward trend, mainly driven by a lesser water intensity of the local economy, a halt in population growth, and a recently link to the emergence of a New Sustainable Water Culture in Catalan society, stands out against the alleged need for new transfers from farthest basins such as the Ebro or Roine rivers.     

Inside and beyond the Petro-State frontiers: geography of environmental conflicts in Venezuela’s Bolivarian Revolution

Venezuela is well known for its century-old oil economy, which has significantly shaped its social fabrics, territories, and eco-systems. Since 1999, the Bolivarian Revolution has led to important transformations in the context of the ‘Socialism of the 21st century’ project, but the extractivist model has deepened. This situation has created or intensified several ecological distribution conflicts, which have been further exacerbated by an extraordinary national crisis unleashed in the period 2013–2016. In this paper, a geography of the 20 most emblematic and representative socio-environmental conflicts in the period of the Bolivarian Revolution is presented. From a comparative political ecology perspective, this article aims to understand how power relations are expressed through territorial configurations and spatial dynamics of resistance, and what are the implications for sustainability. It is argued that a remarkable new situation of environmental injustice is occurring in this period. Despite the ‘eco-socialist’ discourse raised, the current Petro-State has updated the traditional regime on eco-systems, territories, and human bodies primarily by resorting to the assimilation of socio-environmental conflicts through a strategic distribution policy of oil rents. However, it has maintained a pattern of ecological degradation and social marginalization as an outcome of its economic development model. The current context of crisis has fostered intense territorial disputes and conditions for the emergence of new social actors, practices, scenarios, and geographies linked to underground economies and criminal bands, which complicate an already concerning scenario of unsustainability. The current extractivist model is reaching a breaking point. New commodity frontiers have become a main area of dispute.     

They’ll be dammed: the sustainability implications of the Sarawak Corridor of Renewable Energy (SCORE) in Malaysia

This article examines the Sarawak Corridor of Renewable Energy in Malaysia, or SCORE, a US $105 billion infrastructure development plan in Sarawak on the island of Borneo, from a sustainability standpoint. SCORE aims to build 20,000 megawatts of hydroelectric dams along a 320 km corridor comprising more than 70,000 km² by 2030. The article begins by explaining social science methods utilized for its research interviews and site visits. It then argues that sustainability consists of seven principles articulated in international law: prudence, equity, responsibility, precaution, justice, governance, and compatibility. Next, the paper introduces readers to SCORE before assessing it according to these seven sustainability criteria. The paper finds that SCORE erodes environmental prudence by emitting millions of tons of carbon dioxide and feeding industries that will pollute the land and water. It worsens intergenerational equity by exacerbating poverty and consolidating wealth for corporations and politicians. It degrades responsibility by intensifying tropical deforestation and flaunts precaution by downplaying and ignoring risks to water quality and availability. It is unjust, imposing dams on communities and forcibly relocating thousands of indigenous people, mitigates good governance by condoning bribes and kickbacks along with the violent suppression of dissent, and is incompatible with Malaysia’s own energy policy targets and international standards.     

Mixed oligopoly,foreign penetration and China’s environmental policy: a research based on mixed oligopoly model

This paper analyzes how the foreign penetration affects China’s environment policy in a mixed oligopoly framework, and gets several interesting conclusions. First, our result shows that government should strengthen the degree of environmental policy along with increasing proportion of domestic ownership of multinational firms. Second, we show that an increase in domestic ownership of multinational firms raises not only domestic private firms’ profit but also public firm’s profit as well as social welfare. Third, the government will raise the environmental tax to control environmental damage.     

An integrated approach for the benchmarking of production facilities’ environmental performance: data envelopment analysis and life cycle assessment

Environmental impacts have become an important consideration in the manufacturing industry due to increasing public pressure for environment protection and the requirements of recently launched legislations. Data envelopment analysis (DEA) is a widely adopted methodological approach for the benchmarking of the relative efficiency of different production units. Changes in production efficiency may affect environmental impacts. DEA can be used for identifying the most efficient production facility and hence, the environmental impacts generated from the different production lines can then be benchmarked. Life cycle assessment (LCA) is carried out to quantify the full environmental impacts of a product from ‘cradle to grave’. The integration of LCA with DEA, efficiency and environmental impact of different production processes for a certain family of products can be evaluated and benchmarked. The proposed two-stage approach can help to reduce the aggregate environmental impacts of the manufacturing phase and is used to benchmark the environmental performance of several production lines in a manufacturing company.

Coevolving Ostrom’s social–ecological systems (SES) framework and sustainability science: four key co-benefits

Research on social–ecological systems (SES) is scattered across many disciplines and perspectives. As a result, much of the knowledge generated between different communities is not comparable, mutually aggregate or easily communicated to nonspecialists despite common goals to use academic knowledge for advancing sustainability. This article proposes a conceptual pathway to address this challenge through outlining how the SES research contributions of sustainability science and researchers using Elinor Ostrom’s diagnostic SES framework (SESF) can integrate and co-benefit from explicitly interlinking their development. From a review of the literature, I outline four key co-benefits from their potential to interlink in the following themes: (1) coevolving SES knowledge types, (2) guiding primary research and assessing sustainability, (3) building a boundary object for transdisciplinary sustainability science, and (4) facilitating comparative analysis. The origins of the SESF include seminal empirical work on common property theory, self-organization, and coupled SES interactions. The SESF now serves as a template for diagnosing sustainability challenges and theorizing explanatory relationships on SES components, interactions, and outcomes within and across case studies. Simultaneously, sustainability science has proposed transdisciplinary research agendas, sustainability knowledge types, knowledge coproduction, and sustainability assessment tools to advance transformative change processes. Key challenges for achieving co-beneficial developments in both communities are discussed in relation to each of the four themes. Evident pathways for advancing SES research are also presented along with a guideline for designing SES research within this co-aligned vision.     

The quest for environmental justice in China: citizen participation and the rural–urban network against Panguanying’s waste incinerator

Environmental distribution conflicts (EDCs) related to the construction and operation of waste incinerators have become commonplace in China. This article presents a detailed case study of citizen opposition to an incinerator in the village of Panguanying, Hebei Province. Drawing on in-depth fieldwork, we show how this case was notable, because it transcended the local arena to raise bigger questions about environmental justice, particularly in relation to public participation in siting decisions, after villagers exposed fraudulent public consultation in the environmental impact assessment. An informal network between villagers and urban environmental activists formed, enabling the Panguanying case to exert influence far beyond the village locality. This network was critical in creating wider public debate about uneven power and substandard public participation in siting disputes, a central feature in many Chinese EDCs. By transcending local specificities and exposing broader, systemic inadequacies, this case became instrumental in supporting “strong sustainability”.     

Chinese hydropower companies and environmental norms in countries of the global South: the involvement of Sinohydro in Ghana’s Bui Dam

The paper examines the role of environmental norms in Chinese overseas investment in hydropower dams, exemplified by Sinohydro’s involvement in the Bui Dam in Ghana. While the investment of Western companies in hydropower dams in the global South is decreasing owing to changing notions of sustainability in the West, the investment of Chinese companies in hydro dams in Africa, Southeast Asia and Latin America is accelerating at great speed. The emergence of Chinese companies in international markets in the context of China’s Going Abroad strategy has sparked a debate on whether China can be considered a norm-changer in international development. The paper considers this question in the context of the status of environmental norms in Sinohydro’s investment in Ghana’s Bui Dam. The paper argues that the role of international norms in Chinese investment is dependent on two factors: the contractual arrangements under which Chinese companies operate abroad and the political institutions of host countries.

Fishers’ perceptions of climate change,impacts on their livelihoods and adaptation strategies in environmental change hotspots: a case of Lake Wamala,Uganda

Fisheries resources support livelihoods of fishing communities but are threatened by over-exploitation, habitat degradation, pollution, invasive species and climate change. Unlike the other threats, climate change has received limited consideration and reducing its risks requires appropriate adaptation strategies. This study used quantitative and qualitative methods to generate knowledge on fishers’ perceptions of climate change, changes in climate variables and their impacts on livelihoods, adaptation strategies, constraints to adaptation and required interventions to promote adaptation strategies that would enable fishers to build resilience to sustain their livelihoods. We found that fishers were aware of changes in climate conditions manifested by unpredictable seasons, floods and droughts. Fishing remained the main livelihood activity. However, the dominance of fishes had changed from Nile tilapia (Oreochromis niloticus L.) to the African catfish (Clarias gariepinus Burchell). Floods and droughts were associated with damage to gears, boats, landing sites and changes in fish catches and sizes, income from fishing and fish consumption. The fishers adapted by increasing time on fishing grounds and changing target species and fishing gear among other things. Some innovative fishers diversified to high-value crops and livestock. This increased their income beyond what was solely earned from fishing which provided an incentive for some of them to quit fishing. Livelihood diversification was enhanced by use of communications technology, membership of social groups, increasing fishing days and fishing experience. Adaptation was, however, constrained by limited credit, awareness and access to land, which require interventions such as improving access to credit, irrigation facilities, appropriate planting materials and awareness raising. We identified adaptation strategies, which if promoted and their constraints addressed, could increase resilience of fishers to the influence of climate change and sustain their livelihoods.     

Processes of natural soil and vegetation recovery on a worked-out open pit coal mine (Bol’shezemel’skaya tundra)

The processes of soil and vegetation recovery after cessation of surface coal mining operations have been studied for the first time in the far north of Europe. Three stages of primary succession—from primitive algal groups to closed plant communities—have been identified, with the main role being played by soil algae at the zero stage, by herbs at the first stage, and by grasses at the second stage. A close relationship between the early stages in the development of phytocenoses and the stages of posttechnogenic soil formation is demonstrated.     

Non-ferrous metals (Pb, Cu, Zn) needs and city development: the Paris example (1815–2009)

The aim of this study is to explore the urban and/or industrial needs for non-ferrous metals (lead (Pb), copper (Cu) and zinc (Zn)) of Paris (France), a highly developed city conurbation, from the beginning of the nineteenth century to the present. Pb was necessary for the development of urban networks (Pb pipes), Zn for Parisian roofs and Cu for the development of boiler making and electricity. This study is based on economic statistics and shows that the situation evolved from a city transforming ores, having its smelters and transforming metal into goods, to a city where metal smelting has been more or less quickly banned, and where only a small activity of metal transformation into metal-containing goods remains. The patterns of the three metals showed slight differences. The deindustrialization of Paris is also accompanied by a change of the supplying areas over time. Ores were always imported from abroad, because of the lack of French non-ferrous metal mines. But foundries, which were first abroad, had developed in France between the late nineteenth and late twentieth century and were again found abroad at the end of the twentieth century. The transformation of metal into goods left Paris to the benefit of other parts of France first, then of abroad, over time. In a second part, the evaluation of Pb consumption per capita in Paris conurbation shows that Pb needs of Paris conurbation were higher than those of France in the nineteenth century. Then, the Paris demand was satisfied and it became lower than that of France. Both the deindustrialisation of Paris conurbation and its lower needs led to a decrease in the relative weight of Paris for non-ferrous metals, compared to other parts of France.     

A situational analysis of Cameroon’s Technical Operation Units (TOUs) in the context of the landscape approach: critical issues and perspectives

The integrated landscape approach is re-emerging in the global agenda as an approach which can give a fair deal to landscape functions such as climate change response, biodiversity conservation, food security, poverty reduction and economic growth. However, transformational change might be required to enable landscapes respond to these different functions. This is due to the sensitive nature of landscapes to local, national and global economic, social and political drivers. Based on national policy instruments, this paper presents a situational analysis of the landscape concept in Cameroon, operationalized as Technical Operation Units (TOUs) and in the context of the present institutional, social, economic and political features, it examines the rationale for a landscape approach in Cameroon. We notice potential trade-offs, indicating that the landscape approach is an opportunity for TOUs in Cameroon. Firstly, TOUs are characterized by multiple resource regimes with overlapping claims each having a legal land allocation and management plan. Secondly, TOUs are characterized by different stakeholders, with different land-use interests and motives, each controlling key components in the landscapes. Thirdly, the interests and motives of stakeholders overlap spatially and are connected to different sectoral policies at the national level. This setting might threaten decision making and the sustainability potentials of landscapes. Nonetheless, we propose areas for in-depth studies to generate knowledge and information to orientate win–win policy construction for landscapes. This is relevant for the social, ecological and economic objectives that underpin the sustainable development goals proposed in the post-2015 development agenda.

Household preferences and willingness to pay (WTP) for freshwater quality improvement in Pakistan’s Swat River Valley

This two-part study investigates household preferences and willingness to pay (WTP) for water quality improvement of the Swat River in Pakistan. First, a four-point Likert scale was used to rank preferences for water quality benefits without using any financial metric. Results show that households have comparatively strong preferences for non-use benefits. Second, a contingent valuation question was designed to determine WTP for adopting a management plan developed exclusively for water quality improvement in the Swat River. The estimated annual mean WTP per household for water quality improvement is $2.40 when donating to an NGO. Generalizing this value to households living in Swat Valley would generate up to $544,000 per year. The present value aggregate benefit for 15 years would be sufficient to cover the present value of aggregate costs to adopt the management plan. A mandatory program that would require paying for the management plan generates half the WTP compared to the voluntary plan, but is still sufficient to cover costs and may be more feasible than a voluntary program because payment is assured.     

Sustainability education and a new master’s degree, the master of sustainability science: the Graduate Program in Sustainability Science (GPSS) at the University of Tokyo

The University of Tokyo started its Graduate Program in Sustainability Science (GPSS), offering a master of sustainability science degree, in 2007. The GPSS curriculum consists of: (1) knowledge and concept oriented courses, which cover sustainability-related subjects from a holistic viewpoint; (2) experiential learning and skills oriented practical courses, which offer practical exercises to acquire the skills and sensibility required of future leaders; and (3) the Master’s thesis, for which students are encouraged to address complex sustainability problems through a transdisciplinary approach. Sustainability science is not a discipline that can be defined simply by the subjects it deals with, but is an academic field characterized by core principles that include holistic thinking, transdisciplinarity, and respect for diversity. The GPSS has been designed so that students may gain the capacity to understand and practice these principles. The present paper describes how the GPSS has defined sustainability education and designed its curriculum accordingly.
