A growing number of countries at all levels of development have legislation or regulations prescribing the application of Strategic Environmental Assessment (SEA) - and many more are introducing it as part of their policy tools. This is creating unique opportunities for better policy making and planning by incorporating environmental considerations into high-level decision-making and opening new mechanisms to build consensus on development priorities within governments themselves and between governments and societies.
In 2005, with the passing of the revised Law on Environmental Protection (LEP), a new era in environmental assessment in Vietnam commenced, with the introduction of requirements for SEA of a range of national, regional and provincial strategies and plans. The SEA of the Quang Nam Province Hydropower Plan for 2006-15 provides a unique case study, as it was the first SEA undertaken following the requirements of the revised LEP.
