Composting is a useful waste treatment for environmental problem, but composting experiment is challenging due to large-scale requirement. Thus, laboratory-scale reactor is of interest for composting experiment. The capability of laboratory-scale reactor to simulate large-scale composting was determined by assessing the quality of produced compost via germination index.

The study presents the evaluation results of typical PAEs (6 PAE indicators) of the PAE family in water samples from Ho Tay Lake, Hanoi. The quality of lake water in general and in Hanoi in particular is influenced by many factors. The sources of treatment in lake water such as restaurant businesses and residential areas nearby, can degrade lake water quality.

This study aimed to identify the factors affecting farmers’ adoption of sustainable land management (SLM) practices to combat land degradation in Vietnam. Based on the survey data from 826 farmers in three representative regions, the study showed that the SLM model and SLM adoption rate were quite varied due to differences of natural and socio-economic conditions.
