Project Description

Biodiversity and Development of the Hydropower Sector: Lessons from the Vietnam experience

Donor / Partner: CEPF    |    Location: Vietnam

The Government  of Vietnam has embarked on a major expansion of the hydropower sector which is  transforming the aquatic systems of the country. All main river systems are or will be dammed by one or cascades of hydropower projects – each with road access and  transmission lines and linked development shaping the terrestrial, aquatic and  social environment. Recent strategic assessments of the relationship between hydropower and biodiversity in Vietnam  have concluded the development envisaged would bring economic, social and even some environmental benefits. Yet, the  pace and scale of that development is well beyond existing mechanisms and  capacities for addressing social and environmental effects and the full  economic consequences. Hydropower  development is proceeding on a rapid and comprehensive scale for maximising  power and profits but with only rudimentary or even misleading information and analysis on its sustainability and implications for other sectors and social and natural systems. The maintenance of  ecosystem integrity, including the effects of multiple hydropower schemes  within a river basin has been identified by governments of the region and their international partners as a key strategic concern for hydropower development in Vietnam and elsewhere in the Mekong Basin.

There is a need for capacity development, research and information sharing on two fronts: first, in relation to the potential effects of hydropower development on biodiversity and second, in relation to the tools and methods available to integrate consideration of biodiversity issues into hydropower planning and development.

ICEM has produced a a set of materials on the biodiversity and development of hydropower in Vietnam that aims to assist in  filling these gaps, sponsored by a grant from the Critical Ecosystem Partnership Fund (CEPF).

The information kit contains five key documents:



      Targeted at civil society,  Government and donors working within the fields of hydropower development and natural resources management, the document will be an accessible, practical overview of  current knowledge on the relationship between hydropower development and the potential effects on biodiversity resources.


Volume 2: Hydropower and Biodiversity – The use of SEA as an Assessment Tool. This volume is targeted at an audience of civil  society, Government, donors, consultants and others involved in the assessment of biodiversity issues in the hydropower sector.



An overview of relevant biodiversity issues for those carrying out assessments or studies relating to hydropower in Vietnam. It targets civil society, Government and donors and aims to  be an accessible, practical summary of Volume 1 – which reviews current  knowledge on the relationship between hydropower and its effects on  biodiversity as distilled from a number of Strategic Environmental Assessments  conducted in Vietnam.



This policy brief summarises a simple and locally relevant SEA  methodology that can be employed to evaluate the impacts of a hydropower  development plans on biodiversity. The methodology is for use in the assessment of national, provincial or river basin level impacts on biodiversity. Based on Volume 2, this paper provides a snapshot of  practical guidance for the use of SEA as an assessment tool for assessing the effects of hydropower on biodiversity resources.
