Abstract: This study uses the data collected from a household survey on 100 farmers in Lung Ngoc Hoang Nature reserve. Economic efficiency in the present study was estimated from stochastic profit frontier function. Farm household makes an average profit of about 18,33 and 8,02 million dongs in Winter-Spring and Summer-Autumn crop, respectively. The average economic efficiency level was 58,51% and 47,38% in Winter-Spring and Summer-Autumn crop, respectively. The efficiency level largely varied across farms due to the big gap in farming techniques and the ability of choosing optimal inputs across farms. The life cycle assessment method (LCA) was used to assess the environmental impact. The results showed that the impact of global warming in the production of one kilogram of rice was largely due to CH4 emissions from rice soil (94,19%). The use of fertilizer caused the most acidified (94,94%) and eutrophicated (98,03%).
