Examining the Xayabouly dam: Impacts of hydropower dam construction on downstream communities

<p>Hydropower power dam development is a booming industry in Laos and it has the potential to tackle poverty in an environmentally sustainable way. However, currently there is a lack of research that thoroughly analyses the negative impacts of a hydropower dam’s construction phase. This research explores some of these negative impacts of hydropower dam construction on downstream villagers by using the Xayabouly hydropower dam on the Mekong River as a case study. Understanding the impacts of the construction phase is vital in forming policy and developing effective strategies to mitigate future negative impacts from dam construction. This thesis employs a qualitative approach and semi-structured interviews were conducted with downstream villagers about these negative impacts. This research is based on a pragmatist epistemology and employs the matrix conceptual framework to guide this thesis. The results from this study show that the Xayabouly hydropower dam’s construction phase has many negative impacts on downstream villagers’ daily lives. For example, the construction phase has caused irregular flooding, which has destroyed downstream villagers’ agricultural gardens and riverbank erosion has also occurred. Moreover, the results from this thesis show that the construction phase of this dam significantly reduced villagers’ income and nutrition consumption. The construction phase also created significant problems with regards to daily commuting and damaged fishing gear. These results offer important recommendations and implications, which have the potential to inform government policy in the future and to help develop strategies to mitigate the social and economic impacts from future hydropower dam construction in Laos.</p>

Exploring the Impact of Resettlement on Women: A Case Study of the Nam Mang 3 Hydropower Dam in Central Laos

<p>Over the last decade, construction of hydropower dams has increased rapidly around the world, including in developing countries. For many countries including Laos, energy production and export play a significant role in promoting and boosting economic growth and development. Energy production generates substantial revenue and foreign exchange from exporting electricity and expands economic activity domestically. However, construction of hydropower dams also causes negative effects on the people who live at and around the dam site. Some local communities have been affected indirectly, while others require relocation to other areas bringing significant change, including for women. This research explores the impact of resettlement from hydropower dam creation on women by using the Nam Mang 3 hydropower dam in central Laos as a case study. This dam, completed in 2005, required the relocation of approximately 150 households from two villages at the dam site. The research draws on a social constructivist epistemology, qualitative methods including semi-structured interviews, and analysis of relevant policy documents. Interviews involved 18 participants including both male and female from the three affected villages. Results indicate that the resettlement of villagers by the Nam Mang 3 hydropower dam has generally improved living conditions of the resettled communities. Women were found to have greater opportunities to benefit from home-based business, employment and wage labouring. In addition, with better access to modern facilities and services, women have been able to save greater time from agricultural activities and divert this time saving to other economic activities. Overall, access to water supplies, roads, and transport have reduced women’s workload significantly. Access to improved health services and facilities have also improved women’s wellbeing. Girls have greater opportunities to attend school and seek employment in towns. However, this research identified some challenges experienced by the resettled such as the reduction of agricultural and grazing land area, and that new livelihood options were not accessible to all women. Instead of these challenges, the experience with the Nam Mang 3 hydropower project has highlighted one of the key lessons learnt that is worth highlighting for future resettlement programs, which is to have the resettlers fully engaged in the entire process of resettlement and livelihood strategy development.</p>

Dam Safety Emergency Action Plan: A Current Practice for Hydropower Dam in Malaysia

There are currently 104 dams constructed in Malaysia. The dams were built for various purposes; 16 of them were built for hydropower. The dam's reservoir often presents significant risks to downstream areas if a massive downfall release occurs. The enormous downfall could be due to a dam break event, overtopping, and emergency operational release. An incident may occur due to massive flows over a spillway with high-speed discharge or unexpected peak discharge. The obvious impact of the incident is direct to the community in the downstream area. Although there is no dam failure recorded case in Malaysia since the 1900s, the possibility of dam failure occurring is still there. Therefore, the dams must have an emergency action plan (EAP) to prepare the likelihood of the emergency occurrences. This paper aims to explore the EAP practices for dam incident over the region and review the EAP practices of a hydropower dam in Malaysia. Implementing EAP in the emergency response system would minimise the public and environment's impact due to dam failures. The benefit of establishing an EAP is to create better communication and effective responses system among agencies during dam emergency occurrences. This paper revolves around the EAP practices by dam owners in mitigating the risk of dam failure occurrences.

When the Complexity of the Large-Scale Development Project Becomes a Roadblock to Access to Justice

On 23 July 2018, when the villagers gathered around the porch to wrap up the day with a good chat, one of the five auxiliary dams of the Xe-Pian Xe-Namnoy hydropower dam in Attapeu province, the southeastern state of Laos, collapsed. Four days before the collapse, reports of cracks and subsidence started to come through. It should have been enough to prompt evacuation warning issuance by the Xe-Pian Xe-Namnoy Power Co. Ltd (PNPC), a consortium of South Korean companies SK Engineering and Construction (SK E&C) and Korea Western Power Company (KOWEPO), Thailand-based RATCH Group, and Lao Holding State Enterprise (LHSE). PNPC has a Concession Agreement with the Laos government ‘to plan, design, finance, construct, own, operate and maintain’ the Xe-Pian Xe-Namnoy hydropower dam. The warning was issued, but it came too late.

Effects of Hydropower Dam Operation on Riverbank Stability

The increasing number of extreme climate events has impacted the operation of reservoirs, resulting in drastic changes in flow releases from reservoirs. Consequently, downstream riverbanks have experienced more rapid and frequent changes of the river water surface elevation (WSE). These changes in the WSE affect pore water pressures in riverbanks, directly influencing slope stability. This study presents an analysis of seepage and slope stability for riverbanks under the influence of steady-state, drawdown, and peaking operations of the Roanoke Rapids Hydropower dam on the lower Roanoke River, North Carolina, USA. Although the riverbanks were found to be stable under all the discharge conditions considered, which indicates that normal operations of the reservoir have no adverse effects on riverbank stability, the factor of safety decreases as the WSE decreases. When the role of fluvial erosion is considered, riverbank stability is found to reduce. Drawdown and fluctuation also decrease the safety factor, though the rate of the decrease depends more on the hydraulic conductivity of the soils rather than the discharge pattern.
