<p><em>Dams are one of the most important structures in the water resources transmission and storage systems. Thus, given the growth and development of dam construction in the world, evaluating environmental consequences of the dam has high importance. Dams leave positive and negative impacts on the environment. The destructive impacts of dam construction include social, economic, hydraulic, biological, health, and atmospheric impacts, etc., leading to change and complexity. Hence, given the importance of the positive impacts of dams, it is essential that negative environmental impacts of the dam to be minimized for sustainable development.

Dam break is a serious social disaster, which causes a great deal of damage to the society and environment. In this paper, a 3D turbulence model coupled with the Volume of Fluid (VOF) method for the dam-break flood propagating is established, the loss of life resulting from dam failure is calculated by the modified Graham method, a statistical method is used for the economic loss, the main factors for social and environmental impacts are introduced, and finally the linear weighting method is carried out for comprehensive evaluation and analysis of dam-break consequences. The dam-break consequences of Dongwushi reservoir in Handan is taken as a case, the life loss, the economic loss, as well as social and environmental impacts are analyzed, and then a comprehensive evaluation of the dam-break consequences carried out.

Full textAbstract:
Dams, through disruption of physiochemical and biological processes, have water and associated environmental impacts that have far reaching social and economic consequences. The impact of each dam is unique. It depends not only on the dam structure and the attributes of local biota but also climatic and geomorphic conditions. Given the number of existing dams (over 45,000 large dams) and the large number that may be built in the near future, it is clear that humankind must live with the environmental and social consequences for many decades to come. This paper provides a review of the consequences for ecosystems and biodiversity resulting directly from the presence of dams on rivers, and of constraints and opportunities for environmental protection. It illustrates that a wide range of both technical and non-technical measures has been developed to ameliorate the negative impacts of dams. It argues that relatively few studies have been conducted to evaluate the success of these measures and that it is widely perceived that many interventions fail, either for technical reasons or as a consequence of a variety of socio-economic constraints. It discusses the constraints to successful implementation and mechanisms for promoting, funding and ensuring compliance. Finally, it contends that there is a need to improve environmental practices in the operation of both existing and new dams.

PurposeThis proposal is a case study of the Belo Monte dam. The article deals with human rights and environmental violations arising from the construction of the Belo Monte Hydroelectric Power Plant in the northern region of Brazil. This paper aims to evidence human rights violations brought by the construction Belo Monte dam, a glimpse of the COVID-19 scenario and how Brazilian regulation allowed those violations.Design/methodology/approachTo achieve the objective of this article, the Brazilian norms, public policies and the current situation of the affected communities were analyzed, focusing on the human rights violations and the historical timeline of this mega-project. The analysis was directed to the hardcore social sciences, considering analytical and qualitative research.FindingsThe data gathered and the references consulted proved that many human rights violations occurred and that the vulnerability of indigenous and local people increased with the construction of the Belo Monte Hydroelectric Power Plant in the northern region of Brazil. The COVID-19 pandemic exacerbated this adverse scenario since indigenous and local people already had their vulnerabilities increased with the construction of Belo Monte.Research limitations/implicationsThe Belo Monte Dam has had severe and irreversible impacts on the lives of local communities, especially indigenous peoples, as it had destroyed their culture and the environment. The authors were not able to do fieldwork, due to the great distance of the dam. In this sense, the research does not cover all the social–environmental issues, as an ethnographic approach is necessary.Originality/valueThe authors intend to bring attention to harms caused to indigenous people and the local communities, expecting to create an alert of what this kind of project can do to vulnerable peoples' life, especially now with the pandemic scenario, which makes indigenous and traditional communities more vulnerable to diseases due to the loss of their territories.

La represa Salvajina, una de las grandes hidroeléctricas de Colombia, ubicada en el noroccidente del Cauca, en los municipios de Suárez, Morales y Buenos Aires, ha sido una construcción controversial por los impactos sociales y ambientales que ha generado durante la administración de diferentes multinacionales y empresas privadas. La gobernanza se involucra en la administración de esta, pues es permanente la articulación entre Estado sociedad civil y actores privados, donde supone el reto de efectuar la gobernabilidad en el margen legal. La administración de la represa, sus repercusiones socioambientales y la gobernabilidad son tres factores que confluyen para determinar el impacto general de este proyecto frente a la población aledaña. A partir de lo anterior, este escrito intenta ver cómo dicho impacto ha sido remediado, o, en su defecto, cuáles son las tentativas para lograrlo, pues desde una perspectiva críticoanalítica, el manejo y regulación del Estado frente a los actores privados permite que las dinámicas sociales se vean impactadas negativa o positivamente, en la culturalización de nuevas formas de vida relacionadas con la construcción de la represa. En suma, el artículo apunta a que el reto del Estado, en el marco de la gobernanza, y dentro de una armonía teórica horizontal, es suscitar la gobernabilidad entre los actores que buscan beneficio de distinta índole en la represa Salvajina.Palabras clave: megaproyectos, desarrollo, impacto social, impacto ambiental, actores privados, sociedad civil, acción estatal, gobernanza, gobernabilidad.

Full textAbstract:
During the mid-twentieth century the construction of hydroelectric dams in developing countries became a contentious issue in economic and political arenas. Governments and pro-damming parties, particularly those with a direct commercial interest, often consider the dams to be necessary for economic growth, as well as being in the national interest. Others directly impacted by the altered hydrology and ecology, as well as experts concerned with environmental and demographic impacts, are less sure about the benefits of hydro-electric dams. Concerns about the environmental and human impacts of dams are heightened on a waterway such as the Mekong River, which flows through six sovereign states. When the impacts are to be felt across entire regions, ensuring just outcomes for all the stakeholders is crucial to long-term regional political stability and economic wellbeing. Engineers are pivotal in the design and construction of dams, and engineering teams also play an increasingly important role in assisting communities impacted by the altered hydrology. This article focuses on the community and environmental implications of engineering decisions on the Mekong River, and suggests ways in which engineers involved in dam design and construction can play a role in ensuring that socially and environmentally just outcomes are achieved.

Full textAbstract:
This study explores the complex cultural, environmental, and economic forces that converge in the United States' Klamath River Basin, also addressing potential solutions. With watershed modifications and construction of dams in the early-twentieth century, ecosystems have been adversely impacted, creating significant challenges for tribes and wildlife, including fish populations. Competing interests and shifting policy priorities have contributed to a highly contested landscape that may be moving toward more sustainable development. Indigenous communities are playing a central role in moving away from long-term conflict among diverse stakeholders over fish and water resources and toward more recent collaborative efforts in planning one of the largest dam removals in history. Two crucial questions are addressed in this paper: (1) What key factors influence environmental governance? and (2) How might proposed dam removal impact socioeconomic conditions? After a brief literature review regarding spatiotemporal conditions, I employ the Social Ecological Systems (SES) framework developed by Ostrom, together with a general economic evaluation, to provide an important preliminary step toward characterizing the multifaceted and interdependent issues. Meaningful variables are identified by unpacking the interactions of governance institutions, actors, and resources within nested settings. Findings from the benefit-cost analysis suggest that the net economic benefits from deconstruction and river restoration may be between $14 to $82 billion. Finally, I recommend further research and use of the Integrative Dam Assessment Modeling (IDAM) tool.

It is still under strong impact from the Brumadinho dam failure that this article was written. Our main goal is to approach, in the midst of so many social groups hit by this announced tragedy, the reality of the village Naô Xohã, whose population lives on the banks of the Paraopeba River, also victimized by this environmental disaster of consequences not yet dimensioned. As it is a contemporary theme, several press releases were used to compose the narrative, as well as to build a comprehensive review of the literature on the Movement of People Affected by Dams and on socioeconomic and environmental impacts. The proposition, however, is based on an interdisciplinary approach to the theme, which is the impact of the Brumadinho dam failure in Naô Xohã village, mainly due to the pollution that spread over the Paraopeba River. To this end, a fruitful dialogue was established between history, geography, economics and environmental issues.

Abstract In Brazil, given its privileged hydrology, the unexplored economic use of water resources has many dimensions, such as hydroelectric power. This energy will face increasingly rigorous social and environmental impact assessments (40% of potential is located in the Amazon region). Hydropower inventory studies conducted over decades, with solutions such as ecological river flows, that flood smaller areas and reduce natural river flows modifications, are being reviewed. The river extension from dam to the point where the waters are returned after the powerhouse is known as the Reduced Flow Stretch (RFS). Even mega-projects, such as the 11.3 GW Belo Monte dam, are designed with deviating flows reaching an astounding 13,000 m 3/s (excavated material higher than Panama Canal). RFS requires to be carefully studied to achieve appropriate ecological flows, since RFS flows increased reduces the plant's electricity production to the same installed capacity. Balancing RFS requirements and hydroelectric power remains a challenge and, clearly, there is no consensus. Here, we performed an analysis of the main environmental impacts caused by RFS requirements, considering the multiple water use specific for each dam site. The natural variability of river flows provides diversity of habitats and maintains the richness and complexity of biological communities. Therefore, the present study has great ecological, social and economic relevance, since proper evaluation of the RFS requirements avoids potential destabilization of biological communities and even loss of biodiversity. This type of arrangement was more common in dams located in headwaters of rivers, as in the slopes of the Andes mountain range, and in regions like the Alps. There are many hydroelectric plants in South America and Europe that have this type of arrangement of engineering works. But the times are different and the environmental impacts have to be better evaluated. A final aspect also involves the maintenance of ecological flows downstream of dams. Regularization reservoirs need to keep downstream, even if they do not have a TVR, adequate flows that represent minimally the seasonality of the river, with floods and droughts, that propitiate the maintenance of the ecosystems downstream. There are cases such as the Sobradinho Plant in the São Francisco River that has been much questioned in this regard, especially when the climate is changing in the basin, with long periods of drought, and with increasing water use. So this is a very important and increasingly current issue.

Full textAbstract:
The Indian government recently resumed the construction of the Tipaimukh Dam on the Barak River just 1 km north of Bangladesh’s north-eastern border. The construction work was stalled in March 2007 in the wake of massive protests from within and outside India. Experts have argued that the Dam, when completed, would cause colossal disasters to Bangladesh and India, with the former being vastly affected: the Dam would virtually dry up the Surma and Kushiara, two important rivers for Bangladesh. Therefore, this controversial Dam project has generated immense public discontents leading to wider mass-movements in Bangladesh, India, and around the world. The movement has taken various forms, ranging from simple protests to a submission of a petition to the United Nations. Drawing on the “environmentalism of the poor” as a conceptual metaphor, the article examines this global movement to show how environmental resistance against the Tipaimukh Dam has transcended national borders and taken on a transnational form by examining such questions as: who is protesting, why, in what ways, and with what effects. In order to elucidate the impending social and ecological impacts, which would potentially disrupt communities in South Asia, the paper offers some pragmatic policy recommendations that also seek to augment social mobility in the region.

Full textAbstract:
Dams affect rivers and other freshwater ecosystems around the world. The structural performance and service delivery of many dams has seldom been assessed; many are unsafe and no longer deliver designed benefits. Changes in hydrology from climate change will require assessment of safety and operations of infrastructure. This creates an opportunity during relicensing for modification or removal of dams to render them safe, maximise their services and minimise social and environmental impacts. We examined case studies of reassessment of dams from Australia (New South Wales), China, France and the United States that illustrated the following: the management challenge of aging and unsafe dams; unrealised opportunities to improve environmental, social and economic benefits; and the benefits of inventory and relicensing systems. Key elements of an ideal regulatory system to optimise water infrastructure performance are identified, comprising periodic (time-limited) relicensing of all infrastructure overseen by an independent regulatory agency that would take decisions in the public interest through a transparent process, involving public participation. Each dam would have an identified owner who must apply best-available technologies to maximise safety, socioeconomic and environmental performance. Dam renovation could minimise current non-climate impacts, improve migration of aquatic wildlife and even attenuate some climate impacts on freshwater biota.

Background: Brazil´s dam-building plans in Amazonia imply substantial environmental and social impacts. This study evaluates the relationship between social, environmental, and economic aspects and impacts on the health status of the population of Rondônia, Brazil, due to the implementation of the Jirau and Santo Antônio hydroelectric dams. Methods: A qualitative and retrospective Health Impact Assessment (HIA) is used to focus the study objectives. The information is arranged in a structured diagram that enables an outside reviewer to assess the aspects/impacts relationship derived from the construction of the dams. This comes with outline recommendations for health risk management that can orient national health authorities. We selected a narrative review synthesis as the most appropriate approach for the study. Results: The diagram network was built making it possible to analyse the impact changes caused by this enterprise in the health sector. Additionally, the model will serve in the implementation of a complete HIA approach in an attempt to quantitatively map the impacts and to propose recommendations. Conclusion: This effort is very important for highlighting the priorities in the public policy decision-making process, serving as a basis for the Brazilian Health System.

Full textAbstract:
AbstractDam planning and construction is notoriously difficult. It is highly complex, involving a multitude of social, environmental, economic and technological questions that often become politicised in the process; negative impacts are often concentrated on small, vulnerable groups within society, while the benefits are typically spread in a much more diffuse pattern; it requires changing riverine ecosystems, often irreversibly so; and it takes a very long time, with often harsh consequences if mistakes are made. These challenges have generated decades of debate around dams and development, yet it is not clear how dam planning and management can be improved. To address this question, the present study used Q methodology to analyse the views of social and environmental researchers on dams in Latin America on the principles that should guide dam development. The Q analysis rendered three idealised viewpoints: The first suggested that defending the rights of vulnerable people should be the main priority, as a counterbalance to the natural bias towards economically and politically powerful actors within the political economy of dam construction. The second implied adoption of a holistic and scientific vision towards dam decision-making and a focus of efforts on perfecting formal procedures and participatory processes to build better dams in the future. The third called into question the need for dams altogether and concentrated attention on invisible and overlooked aspects of dam decision-making, particularly past injustices, and the rights of indigenous communities to determine their own model of development. Each viewpoint represents an alternative vision for future dam planning and clarifies the choices available to policy-makers and development actors. Moreover, viewpoints give insights into the motivations of those who seek to inform debates on dams and development. While they were identified in the context of dam-decision making, our findings may also be relevant to other fields of sustainable development.

Abstract From the construction of the Trans-Amazon Highway in the 1970's to the current construction of the third largest hydroelectric dam in the world at Belo Monte, the Brazilian Amazon has experienced the impact of large-scale infrastructure projects. When announced, all these projects purported to be the means to achieve progress, national integration, and economic development. The outcomes after several decades are less clear: national indebtedness, significant social and environmental impacts, and regional development taking second place to other goals such as energy production and national GDP. Solutions are suggested to reduce the negative impacts and achieve the goal of improved livelihoods and sustainable development without giving up on national development goals.

In general, redevelopment projects of existing dams can significantly reduce the social, financial, and environmental impacts on a community in comparison to the construction of new dams. In addition, as redevelopment projects of existing dams can accomplish the project purpose more quickly than new construction, the expectation is that such projects will be required more frequently. Tsuruta Dam was constructed in 1966 as a multipurpose dam on the first-class Sendai River. After an unprecedented flood in July 2006, a redevelopment project of the dam began in April of the following year (2007). The project was required to minimize the effect to the flood control function of Tsuruta Dam and to minimize the effects to the power generation company, the dam user. Construction work of the upstream-side cofferdam included a reservoir construction at a significant depth of 60 m or more and a dam body drilling work, and had to be conducted under a complicated and tight schedule. This paper is intended to summarize the Tsuruta Dam redevelopment project as an introduction of the experience and technology obtained and provide some lessons to future redevelopment projects of existing dams.

Full textAbstract:
Due to global warming, a reduction in available water will occur in many watersheds and conflicts concerning water use will take place. This situation is already typical in semi-arid areas, where many reservoirs have been constructed for water storage. Increased energy demands and climate change have led to severe and increasing pressure on aquatic systems. Today, the environmental policies of many countries, such as Brazil, give priority to constructing new reservoirs for hydropower use, and an adopted reservoir and river basin management plan must minimize environmental impacts. Moreover, the production of energy plants will promote more requirements for new dam projects. The Itaparica reservoir is 30 years old, located in the São Francisco river in Northeast Brazil, and is the focus of an environmental study. The article focus of investigations is on the environmental and social impacts after the construction of Itaparica reservoir, governance difficulties, and adopted actions to minimize those impacts. Significant environmental impacts are recognizable, such as increased sedimentation in the inflow area, damage to the lakeshore zone by operational water level variation, water losses by evaporation and infiltration, and degradation of inundated vegetation. Furthermore, a trophic upsurge has been registered with severe eutrophication processes, such as the occurrence of cyanobacteria, oxygen deficit in the hypolimnion, and mass development of macrophytes (Egeria densa). With the creation of the dam there was compulsory displacement of the population of the municipalities around Itaparica reservoir with consequent difficulties of adaptation in the new spaces. Furthermore, there was de-structuring of social relation networks, loss of arable land and improvements, and small and insufficient indemnities for land. In this context, concepts for an advanced reservoir management under consideration of water scarcity are presented and discussed. This study aims to contribute to sustainable reservoir management

Hydroelectric power plants and dams often play an important role in developing countries in terms of their contribution to economy. In accordance with the energy policies of Turkish Republic, Yusufeli Dam and Hydroelectric Power Plant in Northeastern Turkey have been initiated. In this study, the Contingent Valuation Method (CVM) was conducted in Yusufeli Village to determine the environmental costs of the Yusufeli Project. The purpose is to assess the willingness to pay (WTP) of Yusufeli Village residents for restoration of the environmental impacts of the dam project and also to investigate the underlying economic, psychological, and social motivations for WTP. WTP was calculated as US$761 per person which can further be used in the cost–benefit analysis. The results from the study suggest that application of the CVM in rural and urban areas located in the same region can show differences.

Full textAbstract:
Iron ore tailings (IOT) from tailings dams cause significant environmental, economic, and social impacts, which has motivated the search for reuse alternatives. In this scenario, the present work uses reverse logistics to size the resources required to reuse the IOT for road infrastructure. A reverse logistics system was modelled to transport the IOT from the tailings dam to a processing plant and then to the construction site of a road. Resource capacity constraints and operational limitations were considered, and the economic feasibility of the system was analysed. Two scenarios for tailings transportation on the dam/plant route were simulated aiming at a cost less than R$ 25 (US$ 6.13) per tonne: (1) trucks; and (2) conveyor belts. The economic feasibility of both scenarios was proven, with scenario 1 presenting the most promising results – a transport distance of 290 km within the established price limit. This methodology can thus be applied to encourage the large-scale reuse of IOT.

In order to be preferred land-users of the Australian rangelands, mining operations should legacy net environmental, social and economic benefits in the regions that they operate. The positive and negative environmental implications of the Olympic Dam mine in arid South Australia are compared in this study. Criteria assessed include the relative area of affected v. improved landscape, environmental research, pest control and the facilitation of proactive conservation and sustainable diversification outcomes. A call is made for consistent treatment of potential environmental impacts across all rangeland users and the adoption of biodiversity trading to improve regional conservation outcomes. A challenge is issued to miners and other rangeland land-users to demonstrate that, like bilbies, their net environmental effects are beneficial.

This paper focuses on the case of Ríos Vivos Antioquia, a social and environmental movement that fights against the construction of Hidroituango —the largest dam in Colombia— which has produced serious environmental and social impacts on the population surrounding the project. This article analyzes the internationalization of the struggle by this movement through different strategies aimed at defending the Human Rights of its community. For that purpose, this research uses documents produced by the movement and reports of some NGOs as well as interviews with members of RVAM and external collaborators to know their main strategies in some depth. This paper concludes that the strategies of internationalization used by this movement have resulted in the strengthening of the social struggle and the empowerment of the population in that region, which has been particularly affected by the violence in Colombia.

AbstractLarge numbers of dams for hydroelectric power production are currently planned or under construction in many areas around the world. While positive and negative social and environmental impacts of dams are increasingly well understood, little is known about attitudes of the general public towards dams, even though benefits to wider society are often cited to legitimise their construction. In Brazil’s Upper Paraguay River Basin, more than 100 mostly small-scale hydropower dams are planned or under construction in what can be considered a regional dam construction boom. Here we analyse public preferences for strategies to manage dam impacts in the area by investigating the value base that underpins such preferences, drawing on the recently proposed Value Landscapes Approach as our theoretical framework and data from a large representative household survey (N = 1067). We find that contrasting attitudes towards dams, expressed in preferences for economically or ecologically oriented water policies are informed by opposing underlying value landscapes, that is, groups of closely related fundamental, governance-related, and assigned (water) values. While such tensions between opposing values can never be fully eliminated, our research nevertheless gives insights to policy-makers seeking to minimise value conflict and to improve the political legitimacy of public decision-making on dam construction. Moreover, we find that a majority of members of the general public would prefer concentrating dam construction on some rivers while keeping others free-flowing, with direct implications for ecosystems and inland fisheries. This finding may guide policy-makers wishing to develop publicly supported water resources management strategies.

International Journal of Indigenous Health 12, no. 2 (September 20, 2017): 84–102. http://dx.doi.org/10.18357/ijih122201717786.
Full textAbstract:
In August 2014, the Mount Polley Mine tailings dam was breached, releasing millions of cubic metres of tailings water and tailings into Polley Lake, Quesnel Lake, and Hazeltine Creek in British Columbia (BC), Canada. To date, no assessment has identified the communities impacted by this event, nor how they were impacted, from a social or health perspective. This qualitative study uses a community-based participatory research approach to identify (1) First Nations impacted by this incident and (2) impacts to Aboriginal health experienced by these communities. To address these gaps in knowledge, the First Nations Health Authority funded the project team to complete the first two phases of a health impact assessment. This work draws attention to the strong links between First Nations, the land and resources, culture, and associated health outcomes. In considering the importance of Aboriginal health and culturally appropriate health pathways, the project team identified 4 key impacts: environmental dispossession, emotional stress, altered dietary patterns, and changes in physical activity. The similarity in impacts associated with the Mount Polley tailings dam failure for many First Nations in BC is best understood through an in-depth understanding of the importance of the Fraser River as a source of salmon for their communities. This work documents the unidentified and unfulfilled need to ameliorate the extent of emotional trauma prompted by real or perceived threat to salmon health, a threat exacerbated by a lack of reliable information from trusted sources in the aftermath of the breach. Relevant recommendations are also provided.

In June, 1988 I arrived in Senegal to begin my doctoral field research as a member of an interdisciplinary team of social scientists from the U.S., Senegal, and France. At the invitation of the Senegalese government, I was to undertake a multi—year research initiative assessing the projected environmental and economic impacts resulting from cessation of the natural flood on the Senegal River. The main objective of the study was to understand how the impoundment of the Senegal River would affect the socioecological and political economic dimensions of production in the middle valley. It was also to document the responses of farmers, herders, and fishers to changing conditions of the river's hydrology and flooding. The river had been drastically altered in recent years by the construction of two dams, a high dam at Manantali, Mali completed in 1987, and a salt intrusion dam at Diama, Senegal, completed in 1986.

Abstract The environmental impacts of hydroelectric dams in Brazil are investigated in local and regional scales, for the last years. In this paper, we analyze the impact than the establishment of a hydroelectric dam has for the people and their spaces, with the comparative experiences occurred for the North and South of Brazil. We will focus on aspects related to the organization of families, social fight, the compensation and resettlement of people affected by the dam's construction, as well we take a look to the similarities between the two areas, with emphasis on aspects related to migration, mobility and landscapes. For this, we rely on research carried out on the river Uruguay (South), based on interviews, questionnaires and studies of primary and secondary sources, from 2007 to 2014 and also in a survey that is currently being held in Belo Monte area (North), which also uses primary and secondary sources, with fieldwork periods.

Abstract Infrastructure projects, particularly investments in road, rail, and energy, can significantly impact ecological integrity and overall environmental quality. The Belt and Road Initiative (BRI), given its focus on large-scale infrastructure and energy projects, poses significant threats to ecosystems in BRI member countries. These environmental and social risks can, however, be assessed and mitigated by using tools such as Environmental Impact Assessment (EIA). Through examining the EIA process of a large-scale hydropower development project in Myanmar—the Myitsone dam project—the main aim of this article is to show why it is necessary to apply the concept of ecological civilization to Chinese foreign investment projects in Myanmar and other Association of Southeast Asian Nations (ASEAN) member countries. Analysis of the project’s EIA illustrates significant shortcomings for both the public participation process and the overall report’s ability to adhere to good practice and include the full extent of project impacts. Projects, such as this, that cause community conflict and environmental and social harm, do not fall within the stated ‘win-win-win’ objective of the BRI. The article concludes that, unlike the flawed Myitsone process, EIA combined with other requisite public participation processes associated with BRI projects have the potential to foster improved community relations and a green BRI that results in more equitable development in ASEAN. A series of significant opportunities to further green the BRI are identified.

Full textAbstract:
Implementation of big water projects requires that their funders, contractors, and government officials will move projects forward ignorant of their potential social and environmental costs. Economist Albert O. Hirschman raised the issue of ignorance in a widely-read analysis of the factors driving the project process in Latin America, Africa, Asia, and southern Europe. This ignorance, which Hirschman referred to as ‘the hiding hand,’ led to creativity in the case of the San Lorenzo irrigation system in northern Peru, but had lethal consequences in the case of Guatemala’s Chixoy dam project. While Hirschman saw what he called ‘the hiding hand’ as accidental, examination of documents related to large hydraulic infrastructure projects in Peru and Guatemala suggests that in the late twentieth century it was systematically produced by resistance on the part of international financial institutions to addressing the broader political context for project development, or to adequately addressing potential social and environmental impacts early in the project process.

This paper examines the fundamental orientation guiding the Corporate Social Responsibility (CSR) activities in the voluntary report published by Samarco – a Brazilian mining company, identifying how the company perceives itself regarding a severe environmental disaster occurred in 2015. Our analysis applied Basu and Palazzo (2008)'s model based on an organizational sensemaking process to explain how the organization expresses its thinking, how it discusses and acts to cope with the accident expectancy and its consequences. We analyzed the reports that depict the tailings dam collapse, observing whether the risks and damages to the ecosystem would be mentioned and anticipated to the stakeholders. Our evidence point out that the company had not disclosed beforehand any relevant information about the real hazards or critical impacts of its operating activities. After the accident, Samarco seems to maintain its relational posture towards society. However, the practical actions signal that the company is after its own business.

Abstract The present paper contributes to the development and discussion on fuzzy cognitive map (FCM)-based theory for inventive problem solving (TRIZ) for sustainable sediment management in reservoirs. FCM combines aspects of fuzzy logic, neural networks, semantic networks, expert systems, and nonlinear dynamical systems. TRIZ is a constructive methodology that includes practically reproducible models and methods that allow the development of new inventions as well as the teaching of the process, the models, and the methods of creating inventions. A proposed approach in this paper is an improvement methodology that is designed to bring about rapid improvements/changes to processes by defining and implementing the changes that can be quickly identified and easily implemented, thereby reducing the cost and time to bring about improvement and change in reservoirs. Results of this study provide a road map for how to introduce FCM and TRIZ into local sustainable sediment management with consideration of technical and executive requirements, economic factors, social welfare, and environmental impacts.

Water hyacinth (Eichhprnia crassipes) is the most dangerous and worst invasive aquatic weed in the worldwide including Ethiopia, and negatively affecting millions of water resources, fisheries, transportation and social structure. Water hyacinth was introduced in the water bodies of the Rift Valley in 68years ago and currently, the weed is distributed Lake Tana, Lake Abaya, Lake Koka, Koka Dam. The wide distribution and abundance of water hyacinth has led to decreased water availability and sustainable water biodiversity in Ethiopian lakes. However, the spread of water hyacinth is threatening not only water biodiversity but also socioeconomic development and human wellbeing. Water hyacinth in water bodies and nearby areas the local stakeholder has its negative impact on environmental problem and it’s influenced aquatics biodiversity. This review paper aimed to investigate the distribution, impacts and its integrated management option against water hyacinth in Ethiopia. Therefore, based on the review it can be concluded that human intervention is considered as the current problem of water resource in the country and further study is needed to sustain the water resource are needed to keep water hyacinth at unproblematic levels.

Environmental changes, such as sea level rise, are forcibly displacing communities around the world. Forced displacement, inadequate governance mechanisms to address relocation and economic-based adaptation and restoration efforts are leading to devastating social, cultural, health, and economic consequences for the people and communities affected. This article focuses on three tribal communities in coastal Louisiana that are experiencing rapid environmental change and risk of displacement due to historical discriminatory processes, oil and dam-related development projects, oil disasters, increased exposure to hurricanes, and relative sea level rise. Focusing on the political ecology of the communities' experiences of environmental change, including the impacts of displacement and decisions to stay in-place vs. relocate, this paper addresses broader issues of adaptive governance structures and policy implications. Building on Bronen's (2011) rights-based approach to adaptation and Shearer's (2012) approach to a political ecology of adaptation, I argue that governance structures should be put in place that support communities' in-situ adaptation efforts or, if the community decides its current location is no longer inhabitable, to assist community-led relocation efforts. Multiple forms of knowledge should be incorporated into and should inform the structures supporting the adaptation process. I highlight the social, political, environmental and economic context within which environmental changes are occurring in coastal Louisiana through discussion on the loss of the commons, the creation of an energy sacrifice zone, costbenefit based restoration efforts and forced displacement and relocation.Key words: Environmental change, displacement, relocation, adaptation

Water Resources Management 35, no. 3 (February 2021): 1047–64. http://dx.doi.org/10.1007/s11269-021-02771-0.
Full textAbstract:
AbstractReservoir construction projects are frequently met with fierce opposition. Consequently, to mitigate any potential negative impacts, environmental and social impact assessments are usually mandatory. Stakeholder perspectives are often only implicit in such assessments, and the medium-term effects of mitigating actions are assessed at the aggregate level, which fails to take into account unequal disaggregated impacts. In this paper, we design and apply an agent-based model (ABM) built on stakeholder information to conduct an ex ante assessment of the impact of a reservoir construction project in southern Thailand over a 30-year period for individual agents. We incorporate stakeholders’ knowledge into the ABM on the basis of primary data collected during the 2016–2018 period, including workshops with affected farmers to assess their interests and concerns, in-depth interviews with farmers in nearby districts to assess farming behaviors, and the expert opinions of policymakers to assess the relevant regulations and processes. In a case study for which the model was established, the results predict that, overall, farmers will have more farm income if the dam is built. We find that affected people require a standard of living similar to that provided by their previous livelihood as soon as possible after resettlement. By simulating the impacts on individual agents, we conclude that the compensation for relocation offered to affected farmers is not sufficient for sustainable resettlements. Facilitating compensation may increase the speed of project implementation and lead to better outcomes for everyone, including affected communities, whereas failure to reshape the current compensation policy leaves everyone more disadvantaged.

Full textAbstract:
The riverine ecosystems of the Mekong River Basin possess the world’s most productive inland fishery and provide highly productive food crops for millions of people annually. The development of hydropower potential in the Mekong River has long been of interest to governments in the region. Among the existing 64 dams, 46 dams have been built in the Lower Mekong Basin (LMB) to produce up to 8650 MW of electricity. Additionally, of the 123 proposed built hydropower dams, eleven hydropower plants have been nominated for the river mainstream and are expected to install a total of 13,000 MW in the LMB countries. However, serious concerns have intensified over the potential negative economic consequences, especially on fisheries and agriculture in Cambodia and Vietnam. To date, most of the concerns have concentrated on the impacts on hydrology, environment, livelihood, and diversity in the LMB attributed to hydropower development. This paper, however, discusses the fishery and agricultural sectors of the LMB and focuses on the downstream floodplains of Cambodia and Vietnam. The dam construction has caused greater losses of biodiversity and fisheries than climate change in the LMB. The reduction of 276,847 and 178,169 t of fish, 3.7% and 2.3% of rice, 21.0% and 10.0% of maize will contribute to a decrease of 3.7% and 0.3% of the GDP of Cambodia and Vietnam, respectively. Lao PDR may benefit the most revenue from electricity generation than the other country in the LMB, as most of the proposed dams are projected in the country. Cambodia burdens 3/4 of the reduction of total capture fishery destruction, whilst Lao PDR, Thailand, and Vietnam endure the remaining 1/3 losses. The tradeoff analyses reveal that losses of capture fisheries, sediment or nutrients, and social mitigation costs are greater than the benefits from electricity generation, improved irrigation, and flood control of the LMB region. The socioeconomic and environmental damage caused by hydropower dams in developing countries, including the Mekong, is greater than the early costs in North America and Europe. It is proposed that dam construction for hydropower in the Mekong River, as well as other rivers in developing countries, should be gradually removed and shifted toward solar, wind, and other renewable resources.

There is growing interest in how activist bureaucrats change policies; however, it remains unclear how bureaucrats become activists. This article develops a framework for the emergence of bureaucratic activism using the case of Brazilian prosecutors in the Belo Monte dam, a project that drew attention due to its social and environmental impacts. I show that two different types of prosecutors were involved in this case: activist prosecutors, who were committed to the proactive defense of affected communities, and conventional prosecutors, neutral agents that resorted to traditional tactics. Based on 82 interviews, document analysis, and participant observation, I argue that rather than being self-selected, prosecutors within conducive settings engaged in activism after they joined the state by developing long-term ties with local groups. By discovering the problems faced by affected communities and mediating their struggles with other policy actors, prosecutors internalized the grievances of these groups, building commitments to defend their causes.

Purpose The aim of this study is to analyze the capitals moved in decisions about sustainability in narratives from and referring to Samarco Minerações, S.A. under a perspective guided by Bourdieusian sociology. Design/methodology/approach Oriented by historicist ontology and historical epistemology, this research is classified as qualitative, descriptive and documentary, with narrative analysis and case study. The selected organization-case was Samarco Minerações, S.A. The documentary sources considered were sustainability reports, social networks channels and news published in Brazilian newspapers of high circulation. The collected information was submitted to the narrative analysis method. Findings Samarco Minerações, S.A. maintained the sustainability posture before and after the ore tailings dam rupture. The decision models adopted (decentralized) and the moved capitals (economic and technological) after the ecocide revealed a change in the organizational practices in front of a new instability scenario, and the organization’s attempt to reach acknowledgment, legitimacy and power. Social implications The organization was selected because of its involvement in an ecocide. The crime generated economic (suspension of tax collection caused by the organizational inactivity), social (unemployment and deaths) and environmental (iron ore tailings contaminated the region’s ecosystem) impacts. Originality/value The greatest value and contribution this paper offers is an alternative intermediary methodological approach using Bourdieusian micro-sociology to analyze narratives based on capitals dynamics and doxa. This theoretical and methodological approach can prove fruitful for further research in sustainability studies on other topics, and even in other fields.

Abstract The importance of reservoir sedimentation management as a multi criteria problem in practice with multiple decision makers is evident when one considers that the cost of replacing storage lost annually due to sediment deposition throughout the world is in the order of US$13 billion. If sedimentation can be managed successfully, as it has been in some reservoirs, the loss in reservoir storage space due to this phenomenon can be lowered significantly. The purpose of this research is to develop the ordered weighted averaging (OWA) algorithm and apply it and to select the most preferred alternative with different Orness levels for sediment management in dam reservoirs to satisfy the technical and executive requirements, economic factors, social welfare, and environmental impacts. In this way, we present analytic forms of OWA operator weighting functions, each of which has properties of rank-based weights and a constant level of Orness, irrespective of the number of objectives considered. The model are successfully applied to the Dez hydropower reservoir, which has faced serious sedimentation problems. Results of this study provide a general class of parameterized aggregation operators that include the min, max, and average and have shown themselves to be useful for modeling many different kinds of aggregation problems.

A large proportion of the dams in China are earth-rock dams. Regarding the well-studied loss of life and economic consequences due to dam breaks, this paper introduces the causes and modes of earth-rock dam breaks and the corresponding dam-break losses in terms of the social and environmental aspects. This study formulates the evaluation index system and criteria of earth-rock dam breaks’ impact on society and the environment based on a fuzzy comprehensive evaluation method. The results show that the evaluation grade of the social and environmental impact of the dam break of the Liujiatai Reservoir was “serious”. Therefore, similar dams in China should take corresponding measures in advance to reduce the social and environmental impact of earth-rock dam breaks.

Os barramentos construídos para UHEBM impactam na dinâmica do fluxo fluvial de energia, matéria e informação do Rio Xingu, com desdobramentos negativos para o meio biótico, abiótico e para as comunidades indígenas, ribeirinhas e urbanas locais. Nesta pesquisa teve-se objetivo de analisar as consequências da exploração hidroelétrica no funcionamento das paisagens fluviais no Baixo Rio Xingu, através de análises geossistêmicas dos componentes das paisagens. Analisou-se o funcionamento antes do início do represamento da água (1985 a 2014) e após o represamento do Xingu (2016 a 2019). As conclusões indicam como se dá o funcionamento geoecológico de rios amazônicos explorados por hidrelétricas, especificamente aqueles com trechos de vazão reduzida. Essas conclusões podem contribuir no planejamento e gestão ambiental de paisagens fluviais e ajustes na operação da UHE Belo Monte. Repercussion of Hydrielectric Exploration in the Geoecolocical Performance of Amazon Fluvian Landscapes ABSTRACT Hydroelectric exploitation promotes irreversible natural and social impacts, also observed in the Amazonian basins that received the hydroelectric plants of Balbina, Tucuruí, and Samuel. The Belo Monte Hydroelectric Power Plant (UHEBM) is in construction since 2011 in the low-lying region of the Xingu River and started producing electricity in the year 2016. The dams built for the UHEBM impact on the dynamics of the river flow of energy, matter and information on the river Xingu with negative consequences for the biotic and abiotic environment, and for the indigenous, riverside and urban communities. The research’s objective was to analyze the consequences of hydroelectric exploitation on the river landscape in the lower Xingu River through geosystemic analysis of landscape components. The operation was analyzed in the period before the beginning of the water dam (1985 to 2014) and after (2016 to 2019) the damming of Xingu. The conclusions indicate the geoecological functioning of Amazonian rivers explored by hydroelectric plants, specifically those with reduced flow stretches, and these conclusions can contribute to the planning and environmental management of river landscapes and adjustments in the operation of the Belo Monte Hydroelectric Power Plant.

ABSTRAK Indonesia adalah negara yang kaya akan sumber daya alam, baik berupa sumber daya alam pulih maupun yang tidak pulih. Industri pertambangan adalah salah satu aktivitas yang bergerak dalam mengolah sumber daya alam yang tidak pulih yang dapat memberikan dampak positif maupun negatif baik dari sisi sosial, ekonomi maupun lingkungan. Air asam tambang adalah salah satu dampak dari industri pertambangan yang harus ditangani secara serius yang terbentuk akibat reaksi mineral sulfida (pirit) dan logam berat yang terpapar ke media air dan udara yang berasal dari batuan yang terbuka pada saat aktivitas penambangan berlangsung. Sejak tahun 2013, tambang emas Martabe telah menerapkan manajemen air asam tambang (AAT) dalam konstruksi bendungan TSF dengan enkapsulasi sederhana yang dirancang dengan dua kategori utama batuan PAF (Potential Acid Forming) dan NAF (Non Acid Forming) sebagai bagian dari material tanggul TSF konstruksi hilir dan juga mengembangkan basis data karakteristik geokimia material waste di lokasi tambang emas Martabe. NAPP (Net Acid Production Potential) adalah metode standar industri yang digunakan untuk menentukan potensi untuk mengoksidasi dan menghasilkan bahan limbah asam, yang nantinya akan ditempatkan di bendungan TSF dengan metode enkapsulasi. Metode ini bertujuan untuk membungkus material sulfida beresiko tinggi yang sedang di tambang di Martabe dengan lapisan penyegel (sealing layer) dengan mengambil keuntungan dari iklim (curah hujan yang tinggi) dan sifat material ROM (run of mine). Konstruksi lapisan penyegelan dan penjadwalan material waste dilakukan dengan pengembangan strategi operasional pengelolaan limbah yang terperinci dan terintegrasi. Monitoring rutin dengan instrument WRSF (Waste Rock Storage Facility) untuk pengukuran oksigen dan juga dari pengukuran kualitas air menunjukkan kalau enkapsulasi material waste pada embakment TSF berhasil mencegah pembentukan air asam tambang. Kata kunci: material waste, air asam tambang, naf, paf, bendungan tailing, model enkapsulasi ABSTRACT Indonesia is a country that is rich in natural resources, both in renewable and non-renewable. The mining industry is one of the activities that is engaged in processing non-renewable natural resources that can have positive and negative impacts both in terms of social, economic and environmental aspects. Acid mine drainage is one of the impacts of the mining industry which must be dealt with seriously which is formed due to the reaction of sulfide minerals (pyrite) and heavy metals which is exposed with water and air from rocks during mining activities.Since 2013, the Martabe gold mine has implemented mine acid drainage management (AMD) in TSF dam construction with simple encapsulation designed, with two main categories of PAF (Potential Acid Forming) and NAF (Non Acid Forming) rocks as part of construction TSF embankment material downstream and also develop the geochemical characteristics database of waste material at the Martabe gold mine site. NAPP (Net Acid Production Potential) value is an industry standard method to determine the potential to oxidize and produce acid waste materials, which will be placed in the TSF dam by encapsulation model. This method aims to wrap the high risk sulfide material in a mine at Martabe sealing layer to take advantage of both the climate (high rai fall) and material properties of run of mine (ROM). The construction of sealing layer and scheduling of waste is made possible by the development a detailed and integrated operational waste management strategy. Routine monitoring with the WRSF (Waste Rock Storage Facility) instrument for measuring oxygen and also from measurements of water quality shows that the encapsulation of waste material in TSF embankments successfully prevents the formation of acid mine drainage.

Abstract Media communications are least studied in river basin development projects. This paper aims to develop a longitudinal study on how a water resources development megaproject was reported by the world newspapers during its whole life cycle. The development of the Three Gorges Dam project in China (1982–2015) was taken as an example. Newspaper perspectives on eight evaluation themes: time, cost, quality, risk, benefit, social impact, environmental impact, and organization management were extracted from eight newspapers in the UK, the USA, Australia, and Singapore using a content analysis approach. The results show that the media coverage mainly appeared in the construction phase, with peak reporting times occurring in transition periods. Social and environmental aspects were the main concerns of the eight selected newspapers. The tone of the news coverage on the Three Gorges Dam was generally negative. These findings implied that media communications provide valuable insights into the social and environmental complexities of megaprojects in river basin development.

Central Asia, a landlocked region characterised by a generally arid or semi-arid climate and a relatively low rainfall, is traversed by two major river systems. Together, the Syr Darya and the Amu Darya sustain millions of lives and a wide variety of ecosystems. Over three decades in the mid to late twentieth century, a series of increasingly large dams was built on the Syr Darya, radically transforming the river's appearance, behaviour and habitat. In this article, a historian and an anthropologist join forces to explore the impact of these ambitious hydropower projects on the human lives most directly impacted: the dam labour force, many of whom were recruited from across the Soviet Union, but ended up settling in the new towns adjacent to the power plants. How did the dam workers themselves experience the projects to which they contributed their labour? How did they relate to the river that they were called upon to transform?

We argue that social and environmental conflicts regarding development projects are not only the result of deficient EIA implementation but also of historically established power relations and deep-rooted beliefs concerning the economy and socio-spatial relations, of which EIAs are a constituting and enabling element. We focus on governmentality practices from an ethnographic political ecology perspective to trace how the EIA uses the concept of "areas of influence" as a standardized inclusion/exclusion technique, limited by its static nature and functioning as a legitimizing device for governmental interest to expand neoliberal economies in natural resource-strategic regions. Our analysis aims to understand how EIAs used for infrastructure development projects in Latin America have failed to prevent socio-environmental conflicts. At the same time, we question the notions of "space", "influence", and "affected population" behind EIA practices. We conclude that EIAs are a government technology of neoliberal environmental governance that has the potential to exclude the socio-spatial dynamics of local populations while depoliticizing the interests behind the project. With this article, we contribute to the ethnographic approach to governmentality in the context of infrastructure development projects in Latin America and to the understanding of the role of expert knowledge and technologies of government in neoliberal hydro-politics.Keywords: Environmental Impact Assessment, dam, hydro-politics, government technologies, social conflict

ABSTRACT In 2015, the Fundão dam of the company Samarco (controlled by Vale) collapsed, causing a huge wave of mud, causing 19 deaths and becoming the biggest environmental disaster in Brazil. As early as 2019, a new dam rupture took place, with Vale as the responsible company, with around 270 fatalities. Both disasters brought numerous social, environmental and financial problems. This study aims to analyze the impact of environmental disaster of Brumadinho and Mariana on Vale and Samarco Financial Statements, specifically the problems related to provisions, contingencies and environmental processes. The method employed with the case study was a content analysis, and data collection was carried out from Financial Statements, Reference Form and the company’s press channel over a 10-year period from 2010 to 2019. Among the main results, we observed that in 2015, the Mariana dam collapse may explain the significant increase in the coming years regarding deposits and provisions for environmental actions filed against Samarco and Vale. In 2019, it is observed that the amount moved to judicial deposits increased 45 times compared to the previous year. Considering this fact, there is a need for studies that contribute to the transparency of actions for the victims, communities affected by the tragedy, disregard of those involved and the environment, since this is not the first disaster caused by this company.

Site C Dam, a third large hydroelectric project on the Peace River, Canada, could potentially impact many Indigenous groups’ traditional ways of life and cultural lands. Through an explanatory case study, we evaluated the quality of the consultation process between three Indigenous groups and BC Hydro. We reviewed all relevant project documents ([Formula: see text]) from the Canadian Environmental Assessment Agency Public Registry site to identify concerns of three affected Indigenous groups, then evaluated the Indigenous consultation process against best management practices (BMPs) of the International Association for Impact Assessment and the World Bank. Overall, BC Hydro did not apply the international BMPs effectively, due in part to the legislated process and the proponent’s own consultation approach, which limited the ability of the proponent to obtain free, prior, informed consent or identify resource rights. Our findings provide new insights into constraints affecting social impact assessments within and outside of Canada.

Full textAbstract:
Based on the theoretical framework of sustainability tensions, this study aims to analyse how the different stakeholders understand the tragedy that occurred with the Brumadinho Dam in Brazil and its emerging tensions. This tragedy is considered the largest work tragedy to occur in Brazil and one of the largest in the global context. The study was developed from interviews and media documents, that is, secondary data. The results show that the tensions that emerged can be codified into environmental, social, economic, cultural, and institutional groupings. The tragedy may be examined from multiple perspectives, one of which is from the position of the actor involved in the enterprise of the collapsed tailings dam structure. Each actor defends his principles, values, and rights. It is a fact that the lives of the people affected and those who died are not recoverable. Environmental damage can be minimized through long-term mitigation measures, but social, demographic, historical, and cultural damage is irrecoverable. Thus, the study offers the following contributions: (i) the tragedy has different interpretations by the different stakeholders; (ii) paradoxical tensions impact differently on the lives of those affected; (iii) trade-offs from tragedy need to be managed; (iv) Brazil urgently needs to learn relevant lessons arising from the tragedies experienced and described in our article. Therefore, an immense and complex challenge that is on the agenda at that moment in Brazil is ripe for analysis.
