The Strategic Environmental Assessment (SEA) for the "Dien Bien Provincial Planning for the 2021-2030 period, with a vision to 2050" is conducted on the basis of Viet Nam's legislative framework, national and regional planning, as well as the economic development orientation of Dien Bien province. In this article, potentially environmentally impacting content of the planning will be discussed, in which, development scenarios will be proposed and feasible scenario for the development of Dien Bien Province, the development targets, and orientations of important economic sectors will be selected. Three growth scenarios have been proposed for Dien Bien Province: the baseline scenario, the high growth scenario, and the breakthrough scenario. The most feasible one is the high growth scenario. In this scenario, the main specific targets by 2030 are: The average economic growth rate in the 2021-2030 period is 10.51%/year, in which the agriculture, forestry and fishery sector and the industry - construction sector will grow at the rate of 6.54% and 18.64%/year, respectively, in which the figure for the industry sector is 17.30%/year and that of the service sector is 7.15%/year. Regarding the economic structure by 2030, the agriculture, forestry and fishery sector will account for 12.0%
the industry - construction sector will account for 44.3% (in which the share of the industry sector is 15.4%) and the figure for the service sector is 39.6% of the province’s Gross National Produc (GRDP). The research oriented the development of a number of important sectors such as: industry, construction, tourism, trade and services, and agriculture, forestry and fishery. Selecting feasible development scenarios with specific targets will contribute significantly to proposing development orientations for sectors having great impacts on the environment to support the SEA of Dien Bien Provincial Planning for the 2021-2030 period, with a vision to 2050.
