Local communities are frequently displaced from areas selected for environmental protection. Development of nature-based tourism, believed to be more environmentally benign than traditional agricultural systems, has been encouraged by governments and national park managers in the hope of providing alternative livelihoods for local people. This paper examines the extent to which indigenous peoples resettled from within one Vietnamese national park have engaged with the nascent tourism industry, thereby providing a perspective on the success of their resettlement, through the eyes of those communities affected. The perspectives of resettled peoples are contrasted with those of villagers who have continued to reside within the national park, using traditional means of survival, along with new initiatives designed to supplement their livelihoods and to reduce their dependence on national park resources for survival. Resettled villagers are unable to survive on agricultural activity alone, tourism has done little to provide an alternate livelihood and the park environment is still threatened by the use of park resources by resettled communities in their struggle to survive.

There is a big challenge in policymaking relating to plastic management in Vietnam: Vietnam is the one of the biggest global dischargers of plastic waste into the ocean, but the country also has a high demand for plastic for economic development. Recently, Vietnam has adopted the National Action Plan for the Management of Marine Plastic Litter by 2030. According to this Plan, Vietnam would take a circular economy approach in dealing with plastic. This article reviews Vietnamese regulations to prevent the pollution from plastic waste to see whether they support the implementation of the circular economy approach in plastic management and whether they are effective in preventing plastic waste pollution. Based on the review, recommendations are made to strengthen Vietnam’s legal retgime for the prevention of pollution from plastic waste.

A stages-of-change approach would be helpful to understand cancer screening behaviors. This study aimed to identify the compliance and determinants of breast self-examination (BSE) based on transtheoretical model (TTM) and health belief model (HBM). A cross-sectional study was conducted with 296 rural Vietnamese women using a self-administered questionnaire consisting of Champion’s HBM scales, breast cancer knowledge (BCK), integrated connection to neighborhood storytelling networks (ICSN), and TTM stages of BSE. A generalized ordered logistic regression was conducted to identify factors associated with TTM stages of BSE. About 61% of women did not currently perform BSE. Perceived benefit was significant in all stages changes. When changing to the action stage, perceived benefits, self-efficacy, and BCK were significant. When changing to the maintenance stage, perceived susceptibility, benefits, self-efficacy, and ICSN were significant. Determinants influencing BSE behavior were different in each TTM stage, indicating that educational programs should be introduced with stage-matched strategies to increase BSE.

Using various chromatography methods, two known cycloartanes, 24-methylenecycloartane-3β,6β,7β,16β-tetraol (1) and riparsaponin (2), together with two known flavonol glycosides, quercetin 3-O-β-D-glucopyranoside (3) and quercetin 3-O-α-L-rhamnopyranosyl (1→6) β-D-glucopyranoside (4) were isolated from the methanol extract of the leaves of Homonoia riparia Lour. Their structures were determined by MS and 1D-, 2D-NMR spectra, as well as by comparison with those reported in the literature.
