The present paper analysed both sides of the spectrum by looking at two prominent and controversial dam projects – Three Gorges Dam of China and Grand Ethiopian Renaissance Dam of Ethiopia, as well as mentioning some small-scale reservoir cases within the topic. Together with the technology development, population and economic growth and an increasing global responsibility to produce energy sustainably, water dams have become milestone projects throughout the world. However, with the expanding number and scale of hydro-power infrastructures, undesired negative effects such as population resettlement, loss of habitat and probability of water wars have also arisen.
In a world increasingly characterized by numerous concerns over global challenges such as climate change, food security and environmental sustainability, one resource is a key more than ever – water. Despite its irreplaceable survival value for life in general, water resources accompany social development and economic growth as a major contributing element. Among multiple functions of water resources for humanity, one of the popular services that is increasingly critical is electricity generation that is realized through various-scale water dam infrastructures. Even in the current global pandemic situation, hydropower is and is forecasted to remain as the largest renewable power generation type through 2025. The significance of water dams is further emphasized in the light of UN 2030 Agenda because harnessing water power is widely contributing towards achievement of targets such as decarbonisation, access to clean electricity and food security globally.

Excerpt from the Book
Three Gorges Dam, China: The Mega-Dam With Mega-Risks
China’s huge hydropower expansion continues notwithstanding the concerns over socio-environmental impacts of Three Gorges Dam (TGD) which is the most powerful of its kind throughout the globe. Though the idea of the dam was originally discussed during early 20th century, it was reinvigorated especially after the catastrophic floods of 1954 on the Yangtze which resulted in more than 30,000 human casualties (Dai, 1994, as cited in Ponseti & López-Pujol, 2006, p. 153).
Entailing tremendous costs and being surrounded with an intense controversy, the project construction started actually in 1994 and, after three years, the first phase was completed; almost 10 years after the official inauguration of the project, the first generator of the mega-structure was connected to the electricity network marking the closing of second construction phase (Ma, 2010).
At the same time, an estimation done in 2000 indicated that approximately 1,282 locations of cultural, historical and archaeological significance would be desolated under dam waters (Shen, 2000, as cited in Ponseti & López-Pujol, 2006, p. 174). The project was fully operational in 2012, when the remaining turbines and generators started to produce clean energy, but decades of criticism and concerns over the largest dam of the world are also ongoing (Adams, et al., 2013).
Summary of Chapters
Water Dams: Clean Energy or Dirty Weapons?: Introduces the critical role of water dams in global energy production and the rising concerns regarding their social, political, and environmental implications.
Case Studies: Presents an analysis of major hydropower projects, specifically the Three Gorges Dam in China, the Grand Ethiopian Renaissance Dam in Ethiopia, and the Sarsang Reservoir in Azerbaijan.
Three Gorges Dam, China: The Mega-Dam With Mega-Risks: Examines the massive scale of the TGD project, its dual nature as a flood control and energy asset, and the significant socio-environmental controversies it has generated.
Benefits: Highlights the positive outcomes of the Three Gorges Dam, including flood prevention, large-scale clean energy generation, and improvements to inland navigation.
Concerns: Discusses the widespread criticism of the TGD, focusing on forced resettlement, environmental damage, and structural safety issues.
The Grand Ethiopian Renaissance Dam (GERD), Ethiopia: Risks for Sustainable Regional Development and Opportunities for Regional Collaboration: Analyzes the geopolitical tensions created by the GERD and its implications for water security and regional cooperation among riparian states.
Trade-Offs: Explores the tension between Ethiopia's need for electricity-driven development and the existential threats perceived by downstream countries like Egypt and Sudan.
Synergies: Investigates the potential for the GERD to serve as a catalyst for peaceful regional collaboration and shared natural resource management in Africa.
Other Cases: Sarsang Reservoir, Azerbaijan: Investigates the Sarsang reservoir as an example of how smaller-scale infrastructure can be manipulated during regional conflicts, affecting local water access and security.
Discussion: Do the Benefits Worth Risks?: Synthesizes the evidence regarding large dams, arguing that their strategic value is often overshadowed by unaddressed environmental and social costs.
Conclusion: Summarizes that while hydropower is a relevant component of the energy transition, current large-dam practices require urgent reform to avoid long-term environmental and geopolitical damage.

Frequently Asked Questions
What is the core focus of this research?
This work examines the dual nature of large hydropower dams, analyzing their importance as sources of renewable energy against their negative environmental, social, and geopolitical consequences.
What are the primary themes discussed in this paper?
The main themes include energy production, infrastructure-related social displacement, transboundary water conflicts, and the environmental sustainability of large-scale reservoir projects.
What is the central research question?
The paper asks whether the benefits provided by large-scale water dam projects, such as energy generation and flood control, justify the significant risks and controversies associated with them.
What methodology is employed to analyze the topic?
The author uses a literature-based analytical approach, conducting case studies on prominent projects like the Three Gorges Dam and the GERD to evaluate their impacts within existing policy frameworks.
What does the main body of the paper cover?
The main body covers the technical and economic benefits of dams, followed by deep dives into human rights concerns, environmental degradation, and the role of dams as political or military tools in conflict regions.
Which keywords best characterize this work?
Key terms include hydropower, water security, transboundary conflict, sustainable development, and large-scale infrastructure impacts.
How is the Three Gorges Dam evaluated regarding its climate impact?
The paper notes that while the dam is praised for reducing coal-fired power reliance, it is also criticized for methane and CO2 emissions from the reservoir, calling into question its classification as a "zero-emitter."
What specific conflict is associated with the Sarsang Reservoir?
The Sarsang reservoir is discussed as an example of infrastructure caught in the Nagorno-Karabakh conflict, where it served as both a strategic asset and a target, resulting in irrigation and water supply issues for surrounding districts.
What does the author suggest for the future of dam construction?
The author advocates for more inclusive decision-making, the integration of frameworks like the World Commission on Dams principles, and a stronger focus on energy efficiency and truly sustainable alternatives like solar and wind power.
