“…In terms of the biophysical aspects, the main impacts refer to fragmentation of river systems, but also fragmentation of the vegetation, impacts on soil and water quality, impacts on species composition and aquatic biota, and changes to geomorphology (Bakken et al, 2014;Brown et al, 2009;Burke et al, 2009). Regarding social impacts the most critical are displacement, resettlement and migration, changes in livelihood strategies, poor compensation, impacts on culture and social relations, impacts on community health and gender relations, and loss of land and water access (Brown et al, 2009;Lerer and Scudder, 1999;McDonald-Wilmsen and Webber, 2010;Jackson and Sleigh, 2000;Tilt et al, 2009;Tullos et al, 2013;Urban et al, 2013;WCD, 2000;Majid Cooke et al, 2014).…”

Hydropower, social priorities and the rural–urban development divide: The case of large dams in Cambodia

et al. 2015

Hydropower investment is a priority in many developing countries, as a means to increase electrification rates and promote national development. However, neglect of dam-affected people"s needs, can make them vulnerable to the multifaceted impacts of such projects. Using the case of Cambodia"s first large dam, the Kamchay dam, this paper reveals social priorities of affected communities and institutional actors linked to environmental and social implications of large hydropower projects using a preference ranking method. Qualitative research revealed concerns among dam-affected communities which included energy access, livelihood changes, environmental impacts, access to natural resources and compensation. Results also reveal divergence between national and local priorities, which in turn brings about an unequal distribution of costs and benefits of the Kamchay Dam between urban and rural areas. The paper provides recommendations to policy-makers, NGOs and international organizations regarding governance issues, consultation processes and mitigation measures.

“…Moreover, looking explicitly at large dams, despite the increasing literature on the impacts of dams' construction in developing countries, there are still few studies that look explicitly at the questions of distributive and procedural justice and their implications for local development. Most of the studies on large dams focus either on technical/financial issues (Ansar et al, 2014;Sovacool et al, 2014) or socio-ecological aspects (Bakken et al, 2014;Burke et al, 2009;Brown et al, 2009;Lerer and Scudder, 1999;. Among the few studies on justice principles applied specifically to dams' construction, Sovacool and Dworkin 2015 call for an energy justice approach applied to the analysis of energy infrastructure implications on local communities and for a better integration of social sciences approaches in the evaluation of large dams; however there are not yet examples of its application to specific projects.…”

Large hydropower infrastructure development is a key energy priority in low and middle income countries as a means to increase energy access and promote national development. Nevertheless hydropower dams can also negatively impact people's livelihoods by reducing access to local natural resources such as land, water and food. This paper analyses equity-based resource allocation from an ecological economics perspective, by looking at local resource use competition between different uses (food, energy, livelihoods) and users (villagers, urban settlers, local government and dam builders) in selected case studies in Asia and Africa. It also illustrates from a political ecology approach divergences between national priorities of energy production and growth and local development needs.

“…They have a large span of space and time and therefore impose a broad array of impacts on the environment and ecosystems of a river basin (Petts, 1984;Casado et al, 1989;Poff et al, 1997;Rosenberg et al, 1997;Friedl and Wüest, 2002;Brismar, 2004;Burke et al, 2009). What is more, the environmental and ecological influence of project under the background of global climate change is extremely complex; thus, there is considerable uncertainty.…”

Abstract. The interbasin long-distance water transfer project is key support for the reasonable allocation of water resources in a large-scale area, which can optimize the spatiotemporal change of water resources to secure the amount of water available. Large-scale water transfer projects have a deep influence on ecosystems; besides, global climate change causes uncertainty and additive effect of the environmental impact of water transfer projects. Therefore, how to assess the ecological and environmental impact of megaprojects in both construction and operation phases has triggered a lot of attention. The water-output area of the western route of China's South-North Water Transfer Project was taken as the study area of the present article. According to relevant evaluation principles and on the basis of background analysis, we identified the influencing factors and established the diagnostic index system. The climate-hydrology-ecology coupled simulation model was used to simulate and predict ecological and environmental responses of the water resource area in a changing environment. The emphasis of impact evaluation was placed on the reservoir construction and operation scheduling, representative river corridors and wetlands, natural reserves and the water environment below the dam sites. In the end, an overall evaluation of the comprehensive influence of the project was conducted. The research results were as follows: the environmental impacts of the western route project in the water resource area were concentrated on two aspects: the permanent destruction of vegetation during the phase of dam construction and river impoundment, and the significant influence on the hydrological situation of natural river corridor after the implementation of water extraction. The impact on local climate, vegetation ecology, typical wetlands, natural reserves and the water environment of river basins below the dam sites was small.
