I would like to make some comments on the “EIA Report of hydro-power development in the Upper Reaches of the Ayeyarwady River” from the view-points of my specialized fields of research interest such as geography, fluvial geomorphology and environmental science.

It is widely known that there are two Envi­ronmental Impact Assessment (EIA) reports on Hydro-power Development in the Upper Reaches of the Ayeyarwady River.However, nobody knows what and how the China Pow­er Investment Corporation (CPI) has stated in their EIA report.The other one was jointly prepared by Myanmar and Chinese experts, and it is known as BANCA Report. (BANCA stands for Biodiversity And Nature Conser­vation Association).

A 945-page preliminary biological assessment of seven planned dams on the Ayeyarwady (formerly known as Irrawaddy), N’Mai and Mali rivers in Kachin State, Myan­mar collected baseline information on the biodiversity of flora and fauna in the catch­ment area of the dams over a period of five months from January to May 2009.

All expenses of the study were funded by China Power Investment Corporation (CPI). A team of 80 scientists from Myanmar from BANCA and others from the Changjiang In­stitute of Surveying, Planning, Design, and Research (CISPDR) of China conducted the study.

For BANCA Report, the experts involved did not have enough time for the detailed field survey and collection of empirical data due to many such holidays as Kachin’s Manaw Fes­tival and Chinese New Year Festival.There­fore, total number of days spent for the field survey was less than a week, and accordingly one cannot expect too much reliability and validity of data and information from this kind of report.

The EIA Report cannot be regarded as a perfect observation document. Although the survey period needed to take at least about seven months normally, the experts had to conclude the report within five months due to the demands of Chinese experts tocooperate with Myanmar counter­parts.The Myanmar researchers could not have opportunity to read the MoU between the two governments before starting the observation works. As there was no Myanmar Environment Law by then for reference in the coun­try, the facts in EIA Report were com­piled from available sources.

The process of environmental impact as­sessment cannot be completed within one time. Both direct and indirect impacts have to be observed before and after the project continuously. Based on the observations, the experts will also need to assess and examine whether the ways of lessening impacts are effective or otherwise.

EIA is a process that should be publi­cized transparently. Only then there will be no doubt about the project. There will be both advantages and disadvan­tages whenever development projects are implemented.Serious disadvantages must be reduced with high degree of lessening plans.Such lessening plans are sometime of great value, while small impacts can be solved easily.Therefore, the responsible persons are suggested to support EIA process from beginning to end.

The Report has placed much emphasis on the negative impacts of damming river on the ecosystem, flora & fauna, biodiversity, natu­ral habitats and environmental conservation of the study area.

Prior to the implementation of a gigantic developmental project in a large drainage or river basin, many more detailed re­search projects need to be carried out by experts, scientists, specialists and pro­fessionals from various disciplines taking a sufficient amount of time.

The EIA report should be based on the guidelines and standards of World Bank and the like.

As underlying geology (lithology and struc­ture) plays a very important role in the con­struction of a dam, a reliable geological map is needed for depicting different types of rock layers and geological structure in details at the dam site, especially in the potential flood­ed area after the completion of a reservoir.

As this Ayeyarwady Myitsone area has been weak in security for many years, not many detailed geological surveys have been done so far, and consequently no detailed geological maps and/or data are available. Based on the existing geo­logical maps published before and after the independence of Myanmar, the geological conditions of the Myitsone area and its en­virons are actually not suitable for the con­struction of large dams and dam- cascade.The area in question is largely composed of serpentinite, one of the ultramafic igneous rock types, which is durable and resistance to considerable extent.However, when en­countered with the water in a reservoir, the serpentinite can cause a great danger to the dam.

The dam site lies in the Seismic Zone 4 (i.e. Severe Zone). In other words, this area can experience the earthquakes with the maximum intensity of Mercalli Scale 8 to 9. The active Sagaing Fault is approx­imately 15 miles away to the west of Myitsone Area. The engineering structure must be quite resistant to severe earthquakes and ruptures. Those research works and find­ings of Myanmar geologists should be taken into consideration by the Chinese counter­parts, and they in turn should disclose their findings to Myanmar geo-scientists.

The construction of dams on the Ayeyarwady River should be avoided due to the changes in downstream hydrology which may affect navigation, riverine ecosystem and deltaic ecosystem, and will lead to negative impacts on the economy.

The Ayeyarwady dams will threaten biodiversity. Eco-regions which are na­tionally important, regionally significant and globally outstanding will be directly affected by clearing and logging of the inundation areas and construction activities for a series of dams in Kachin State.Of particular con­cern are the loss and fragmentation of key ecosystems and the loss of key, endemic and endangered species of both flora and fauna. Definitely there will be negative impacts on potential of availability of traditional me­dicinal plants.There will be severe negative impacts on regionally significant and globally outstanding three eco-regions, one center of world plant diversity, and severe impacts on key biodiversity areas and conservation corri­dors of Myanmar.


key biodiversity areas and conservation corri­dors of Myanmar.

Downstream impacts to the whole Ayeyarwady Drainage Basin need to be examined as the river is vital to the country. The Ayeyarwady River is the most important lifeblood river in Myanmar.Millions of people are depending on this mighty river for their livelihoods.It also acts as a conduit of communication to over sixty million of people.The fragmentation of the Ayeyarwady River by a series of dams will have very serious social and environmental problems not only at upstream of dams but also to very far downstream to the coastal delta.A longer and more comprehensive EIA investigation is strongly recommended in such a big and sensitive hydropower develop­ment which may give rise to very significant adverse impacts.

The Ayeyarwady dams will have se­vere negative impacts on livelihoods, public health and safety. On account of construction of a cascade of dams in Kachin State there will be severe negative impacts on livelihoods and habitations of grassroots people of the region, disappearance of some wild rice varieties and their ancestors, dis­appearance and forever loss of the cultural heartland of Kachin people.

A Social Impact Assessment (SIA) must be conducted and decision mak­ers should balance positive and neg­ative aspects. Proper SIA must be done before construction of each dam to know real impacts on livelihoods.The main draw­back of this EIA Report is the lack of SIA at all. Therefore, systematic SIA must be carried out by competent so­cial scientists. Before approving the con­struction, the decision-makers are strongly urged to fairly balance between the negative and positive aspects of dams.

Affected people should be consulted for their consent, and local people are currently against the projects. The public should be disclosed about the hydropower dams and resettlement programs by having public meetings. The majority people of local ethnic groups oppose construction of the Ayeyarwady dams especially Myitsone hydropower project.They consider the Ayeyarwady confluence as the cultural heartland of the Kachins.For the longevity of dams to be constructed in Kachin State, the opinion of grassroots peo­ple should be brought into due consideration.

The benefits of the project need to be shared equitably. There must be a fair and equitable sharing of benefits coming out from this hydropower development among the stakeholders concerned, including the people of Myanmar in general and Kachin people in particular.The EIA should be publicly released. The main audience for this docu­ment is the people of Myanmar.

Major salient weaknesses discovered in the EIA Report of Hydro-power De­velopment in the Upper Reaches of the Ayeyarwady River can be summarized as follows:


1. Downstream impacts, including assessments of river flows, sediment discharge, water levels, flooding patterns, salt water intrusion into the Ayeyarwady Deltaic Region, fish habitats, and riverbank erosion have not been studied yet.


2. Baseline data on the Ayeyarwady River Basin as a whole has also not been collected. [Actually, a drain­age basin or river basin should be considered as a fundamental geomorphic unit which needs to be thoroughly studied applying the ho­listic approach and general systems theory.]


3. Social, health and economic impacts of the proposed dams have not been addressed yet.


4. Consultation with affected peoples has not been conducted yet.


5. Strong conclusions and recommen­dations that can ensure the concerns raised in the Report are not fully addressed and included.


In conclusion, water resource management must be based on principles of ecological sustainability and social justice.Affected communities - upstream & downstream - must be protected.To ensure this as well as transparency and accountability, national reconciliation and genuine democratiza­tion is desperately needed in Myanmar.All stakeholders should be urged, if possible, to immediately stop these harmful dam proj­ects in the Ayeyarwady Drainage Basin, and to preserve the river for future generations.And, more importantly the economic, social, health, security and environmental impacts of dams throughout Myanmar must be pub­licly disclosed from now onward.
