The research aims at estimating the tourism and recreational values of Can Gio Mangrove Biosphere Reserve, Ho Chi Minh City, specifically, assessed the tourism potential via the willingness-to-pays of respondents (including domestic tourists and local people) for sustaining the landscape and regenerating natural resources as well as protecting the environment. The zone travel cost method was adopted in this study, to firstly plot the demand curve and then to estimate the values of recreation for visitors, eventually, come up with the total economic value of natural resources and environment of the research site. The results showed that the total recreational value of this resort is 6,542.3 billion VND while the consumer surplus values that visitors would receive from tourism activities are 1,389 billion VND. Each the tourist is willing to pay 107 thousand VND to improve the quality of tourism services, upgrading the infrastructure, sustaining the environmental quality and protecting the pristine look of the landscape.

Can Gio Mangrove

In the context that Vietnam develops for international integration, the government has oriented socio-economic development to develop in a sustainable way, not kind of development at all costs. This is clearly shown through the fact that ministries and governmental institutions have adjusted policies and target programs to achieve the millennium goal set by the United Nations to serve the action plan for the sustainable development of the entire nation. From the point of view of sustainable development, many countries around the world have calculated green GDP instead of normal GDP to see that economic development must be closely linked to social progress and environmental protection. Throughout many years of research on the total economic value of a system of environmental resources, especially the total economic value of the humanistic ecology system of Can Gio Mangrove Biosphere Reserve, the author found that there are similarities in the calculation of green GRDP and that of the total economic value of a geographic area. This paper aims to present a conceptual framework to calculate the green GRDP for the Can Gio Mangrove Biosphere Reserve, using total economic value methods. The author also links the United Nations documents and the Statistics Law with the Government of Vietnam's guiding documents for implementing the law to formulate a green GRDP calculation conceptual framework using the methods of total economic value calculation. To calculate the Green GRDP of Can Gio Mangrove Biosphere Reserve by using the total economic value methods is an illustration to convince the validity of the Green GRDP Conceptual Framework. Hopefully there will be many comments from scientists and managers to be able to unify how to calculate green GRDP for mangrove areas and to move towards calculating green GRDP for the national economy, in order to manage the balance between "conservation for development" and "development for conservation" according to the trend of sustainable development.

Study site is a part of Can Gio mangrove biosphere reserve in Can Gio district, Ho Chi Minh City. At present, this area is eroded strongly due to the effects of hydrodynamic impact. Based on the field measurements of coastal profile and shoreline changes from 2013 to 2017 and combination of remote sensing method and GENESIS model, the erosion and deposition processes in 5 years are evaluated and analyzed. The results show that the study site keeps eroding over time and trend to continue in the future. Moreover the study also shows that the erosion rate in the northeast monsoon is higher than that in the southwest monsoon. These results are very important in contribution to shoreline change studies.

Marine Salt

Microplastics (MPs) are synthetic polymer pieces with a size of less than 5 mm that are ubiquitous in the marine environment. They have been recently detected in several wild species and sea products. An indispensable condiment in human food is marine salt that is produced from seawater. Since toxicity studies report potential health impacts when plastic debris is ingested, more attention must be paid to the MP contamination of sea salt and the underlying reasons for this. The central aim of this study is to evaluate the MPs contamination level of sea salt in correlation with the MPs contamination level of seawater in Vietnamese areas. Micro-Raman spectroscopy was employed to determine MPs in the samples collected from three artificial salt pans of Vietnam. The result revealed the presence of MPs in all study areas—Vung Tau (VT;14.54 MPs/L seawater and 114.67 MPs/kg salt), Ly Nhon (LN; 13.14 MPs/L seawater and 63.59 MPs/kg salt), and Can Thanh (9.42 MPs/L seawater and 93.69 MPs/kg salt). The comparisons highlight close correlations in the percentage, shape, size, and color of MPs, especially polyethylene, polyethylene terephthalate, and polypropylene particles extracted from the seawater and its salt. This study proved that seawater is a plastic pollution source for salts produced by traditional seawater evaporation. The study also alerts the prevalence of MPs in the environment and human consumables, thereby indicating that actions must be taken to reduce the pollution of water sources in Vung Tau and at the UNESCO Can Gio Mangrove Biosphere Reserve and improve salt production and refinery processes in order to minimize the number of MPs in final salt products for safe consumption.

This study investigated benthic diatom communities of mangrove forests at Can Gio Mangrove Biosphere Reserve, Ho Chi Minh City, Vietnam. Samples were collected on two substrates: mud surface and living root surface. Sampling locations were placed in four types of mangrove vegetation: mud flat (without vegetation), Rhizophora forests, mixed forest of Avicennia-Rhizophora and Avicennia forest along three tidal creeks during wet and dry seasons of 2004-2005. A total of 348 taxa were identified, of which 100 taxa belong to the Order Centrales and 238 belong to the Order Pentales. There were significant differences in benthic diatom species richness and species composition between two types of substrates and among different mangrove forest types. The difference between wet and dry season was not significant.

Ecotourism is considered as a pre-eminent form of tourism that helps to balance economic purpose and conservation of natural and cultural values of the area. However, in order to conduct efficient ecotourism activities, besides a specific ecosystem, the locality must have proper human resources as well as responsible tourists. This paper presents some findings from our research on how the labors’ planning and working for ecotourism spots in Can Gio to meet the requirements of ecotourism. A survey with tourists was also realized. The result raises some concerns about the sustainability of ecotourism in Can Gio.
