“…In fact, the frequent water regulations may reduce the influx of water sediments, decrease the biodiversity of animal and plant species, and contribute to soil erosion, particularly in Cambodia and Vietnam, which are mostly affected [14,19,21,142,143]. Other direct challenges connected with the water peaking phenomenon [88,99,144,145] include sudden water fluctuations [44,146,147], changing water color, and deteriorating ecosystem health due to the algae bloom [148,149], which produce methane emission caused by stored carbon in bottom sediments [150,151] and accelerate other cumulative environmental processes [152][153][154]. Because many negative consequences occurred as a by-product of multiplying the benefits [155][156][157] and securing the hydropower development in local environments [40,71,158], the large-scale water projects attract significant media attention and numerous speculations beyond the data [24,25,159,160].…”

Politicization of the Hydropower Dams in the Lancang-Mekong Basin: A Review of Contemporary Environmental Challenges

2022

To date, hydropower dams raise numerous interpretations about their impact on the Lancang-Mekong River. While most research studies analyze the negative aspects of hydropower development on people’s livelihoods and local environments, the hydropower sector was historically one of the most iconic economic segments facilitating transboundary water cooperation for decades. By using the constructive discourse analysis and critical political ecology approach, the presented text (1) outlines the current environmental narratives over the Lancang-Mekong hydropower development and (2) explores the politicization of the Chinese mainstream dams. The data were collected upon the multi-level content analysis of relevant sources and double-checked with the Lancang-Mekong Cooperation and Conflict Database (LMCCD) monitoring over 4000 water-related events among six riparian countries between 1990 and 2021. Our data show that (i) there is a stark contrast in positive and negative narratives over the rapid hydropower development, (ii) the impact of mainstream dams on the river is more often discussed than that of tributary dams, (iii) implications of the hydropower dams are often interpreted upon the non-traditional research inputs rather than widely accepted studies, and (iv) developing the contradictory arguments through social and public media contributes to greater polarization of the multi-stakeholders’ viewpoints in the accountable research dialogue.

“…Indus, Jhelum and Chenab could be taken as one pertinent example to this stride (Singer, 2007;Immerzeel et al, 2009;Kult et al, 2012;Jones et al, 2008). Even this single study is expected to nurture to a number of additional studies so as endeavor further to comprehend the behavior of flows upstream of the projects (Ali et al, 2020;Nilson and Bergren, 2000;Gordon and Mentemeyer, 2006), for making the operation of the works more efficient vis-a-vis sediment loading from the upper catchments and their subsequent management (Shi et al, 2021;Gilbert and Wilcox, 2020;Wohl et al, 2015).…”

Economics of water is certainly multifaceted. To each of its dimensions in turn,there exists a whole range of economic activities. The paper under reference would attempt to introduce one of such an area where various dimensions of the economics of water could be seen as alarmingly visible, i.e. the eastern component of the world-famous Indus Basin, which was virtually detached from the western part because of a water treaty signed amongst the two neighboring states. The eastern part of the basin includes the rivers Sutlej, Beas and Ravi, as well as their tributaries, and western part includes rivers Indus, Jhelum and Chenab along with their tributaries. For discussion on the detrimental effects of hydraulic constructions in upper catchments of both the eastern and western sides of the basin, the pre-treaty and post-treaty scenarios were required to be taken into consideration. The findings reveal that the construction of dams on the upper catchments eventually turned out to be the cause of a severe decline in the river flows. The dam construction on the eastern rivers in particularseriously deteriorated the total environment of the eastern side of the basin as the water compensation through the link canals did not matcheven a part of an earlier flow pattern.The western side, however, asking for entirely a different approach, has not been made a part of this study.
