Pak Mun Hydropower Dam, Thailand

Description

Approved for construction in 1989, the Pak Mun hydropower plant was commissioned by EGAT (Electricity Authority Of Thailand) and was completed in 1994. It was co-financed by the Thai Government and the World Bank for US$ 260 million (6.507 Billion Baht). The Pak Mun Dam has an annual generation capacity of 290 GWh and sits 17 meters tall, 300 meters wide, and its reservoir is 60 square kilometers (6). The main purposes were for electricity generation and irrigation. However, despite the dam’s capacity, Pak Mun generates 136 MW in the wet season and only 40 MW in the dry season. A study completed by the Thailand Development Resource Institute (TDRI) to assess the dam’s development effectiveness revealed a gap between the anticipated project benefits and those that occurred in practice (3). The project displaced 1,700 households and approximately 25,000 people were affected either directly, or indirectly. Major impacts of the dam include: a decrease in fish species, destruction of biodiversity along the river basin, erosion of riverbanks and naturally fertilized soil, and changes in water flow for irrigation. Ecosystem changes affected the villagers as the majority of their economy was based on fishing, agriculture and use of natural products from the riverside forest areas. The villagers were not included in the decision-making at any stage of the project and still have not received fair compensation for their losses.

Impacts
Environmental ImpactsVisible: Biodiversity loss (wildlife, agro-diversity), Floods (river, coastal, mudflow), Food insecurity (crop damage), Loss of landscape/aesthetic degradation, Soil erosion, Large-scale disturbance of hydro and geological systems, Reduced ecological / hydrological connectivity
Potential: Deforestation and loss of vegetation cover, Surface water pollution / Decreasing water (physico-chemical, biological) quality
Health ImpactsPotential: Malnutrition, Violence related health impacts (homicides, rape, etc..) , Health problems related to alcoholism, prostitution
Socio-economic ImpactsVisible: Increase in Corruption/Co-optation of different actors, Displacement, Loss of livelihood, Loss of traditional knowledge/practices/cultures, Militarization and increased police presence, Violations of human rights, Land dispossession
Potential: Loss of landscape/sense of place, Lack of work security, labour absenteeism, firings, unemployment

Do you consider this as a success?No
Why? Explain briefly.Studies to assess the impacts of the project on local livelihoods and local ecosystems were not completed until after completion in 1994. In response to concerns about over 150 fish species, a concrete fish ladder was installed in 1996, but its design was flawed and did not allow for upstream migration. There has been a substantial lack of compensation given out to the affected people as well as concerns over the lack of information provided over the course of the project. Study results have, however, led to an annual 4-month opening of the dam’s floodgates. Despite an agreement from the government to open the gates, this is only a small victory as the gates are only opened after local communities mobilize to protest each year. (2) (3) (5) (6)
