Participate in the Mekong basin development planning process: Initial findings of basin-wide development scenario assessment are now available - call for comments and inputs


The water resources in the Mekong basin are a valuable asset that can be used to help reduce poverty and increase national and regional growth. Ensuring that this happens in a fair manner, and that the development of one part of the river system does not impede on the benefits or rights of other water users, requires careful planning. Part of this planning process is meaningful stakeholder participation and ownership.

This page is designed to help stakeholders submit their comments and inputs to the ongoing Mekong Basin development planning process, led by the four countries in the Lower Mekong Basin.

The process of engaging with stakeholders is part of the Stakeholder Participation and Communication Plan and one of the follow-on actions agreed at the 2nd Regional Stakeholder Forum on BDP in Chiang Rai (15-17 October 2009).

Please use the form below to comment on:

  1. The initial findings of the basin-wide development scenario assessment, which provide a preliminary picture of cumulative hydrological, environmental and socio-economic impacts of different levels of future water resources development in the Lower Mekong Basin. The scenarios consider the impacts of developments in the Upper Mekong Basin as well as climate change. The final results of the scenario assessment and consensus among the LMB countries and stakeholders on acceptable scenarios, will help shape a '‘development space' for the further development, use and management of the Mekong water and related resources.

    Power Point presentations on these initial findings are also available to facilitate quick review.

  2. The methodologies for the assessment of the considered basin-wide development scenarios that are being used to produce the assessment findings.
  3. The IWRM-based Basin Development Strategy a document written by the riparian countries outlining the Mekong countries' agreed directions for the development, use, management and protection of the Basin's water and related resources. The implementation of the Strategy will influence national planning, decision-making and transboundary water governance processes.
  4. Any other factors that you or your organisation thinks will influence poverty alleviation through the development, use or management of water and related natural resources in the Lower Mekong Basin., including but not limited to: hydropower, agriculture, fisheries, environment, flood control, and navigation watershed management.

Update on the progress and roadmap of the scenario assessment and the preparation of the IWRM-based Basin Development Strategy is provided on monthly basis.

Other documents on the Basin Development Plan Programme are available at the MRC/BDP website

There is a separate submissions page for eliciting public submissions on the proposed hydropower schemes on the mainstream Mekong.

Please use the form at the bottom of this page to make a submission. Your submission will be posted on the discussion webpage below and sent directly to the MRC team supporting the national Governments to: (i) complete the economic, social and environmental assessment of the development scenarios and (ii) use the outcomes of basin-wide discussions of the assessment results for the preparation of the IWRM-based Basin Development Strategy. Your submission will form an important input into the Mekong Basin development planning process.

Any member of the public, NGO, civil society organisation, government body, private business or other organisation may make a submission.

Please note: Representative extracts taken from submissions may be published by the MRC. If you do not wish to have your name attributed to any part of your submission in a public forum, please indicate that you would like to remain anonymous. Your contact information will not be shared with any third party. Submissions made under false names or pseudonyms; or that appear to be an attempt to impersonate a third party will not be considered.

Please limit your submissions to maximum of three pages. If you have additional supporting documents, such as scientific or consultant’s reports, published or peer reviewed data, photographs or other evidence, please include these as attachments to your submission via the e-mail address: Please ensure that these do not exceed five MB.

Submissions in this form should be made in English. If you wish to make your submission in Cambodian, Lao, Thai or Vietnamese languages, please do so through the e-mail address:

This seems to be a multi-national project. However, in order to alleviate poverty through participatory approach , there should be an grass roots level instutional network involving the ground level end users of water from the project as well as relevant stakeholders. End users' voice is decisive and they who face the real problems not the top level decision makers. I suggest an institutional network based on co-operative principles could play a vital role on sustainable basis which is organised and managed by the people themselves.It is a self-help organization which meets the needs of their members for their socio-economic development.

Assessment findings seem to indicate Vietnam to be a gain state thanks to dams on the Mekong River. I don't think so.

One of my key concerns relating this subject is that: Annual floods from the Mekong River provide large amount of rich sediments every year in flood season to build up the Mekong Delta and enable the delta to be productive for agriculture. Large dams, particularly ones on the mainstreams, effectively stop this natural process of sedimentation in the delta. The delta would be more vulnerable to sea level rising situation due to lesser amount of sediment supply thanks to the dams. This important and serious impact was not mentioned and assessed in the assessment methodology.

Table 2 Assessment criteria

The "issue" identified for 2.5 Conservation of Biodiversity is: Impacts of flow management changes on endangered species

Hydropower development requires significant other developments, such as forest clearing, roadbuilding, mining, and other large-scale industrial extraction. In addition, resettlement of local people and mitigation are likely to include increased market-based agriculture and aquaculture. Therefire, the following issues must also be considered as highly significant with regard to biodiversity: Destruction of lowland forest habitat, increased access for hunters and poachers, introduction of invasive species, use of pesticides and herbicides for aquaculture, forced changes in terrestrial migration patterns due to inundation.

As a former hydraulic Expert Engineer , I am interested by the Mekong basin development. I have read some documents downloaded on the MRCMekong site and arrive at the following conclusion:

Hydro dams in upper basin , particularly in the chinese basin, will have negative impact on the TonleSap Great Lake: reduction of the area and the duration of the floodplain. Some authors estimate this impact can reduce the capture fishery product in the Great Lake by tens percents; this eventuality is not acceptable.

One investment which can mitigate this negative impact is the building of a barrier dam at Phnom Penh. The construction of this barrier is technically and economically possible; it can give Cambodia a hydro power production of hundreds MW all year round ; it is also benificial for Viet Nam thank to a larger discharge of freshwater during the dry season and surely during the dry years.

I would like to use the outcomes of basin-wide discussions of the assessment results for the preparation of the IWRM-based Basin Development Strategy. I hope IWRM-based Basin Development will be developed by participation engagement.
