“…Thus, marine resource managers should think about developing training programs to enhance the depth, interactivity, and educational value of activities in reef activity sites when implementing reef impact reduction programs. Moreover, this finding indicates that the issue of carrying capacity is a significant attribute for reef impact reduction management, which is supported by other work [38,55].…”

“…Based on the results of our study, we propose the following conceptual management framework ( Figure 2). First, the main evidence of this study reveals that marine protected area managers should incorporate control over the number of divers, control of the snorkeling experience area, controlling the way to the snorkeling site, educational training, marine police, and a welfare foundation for coral reefs as elements of effective frameworks for the promotion of reef impact reduction programs [4,8,11,38,40,42,47,[55][56][57]73]. Second, incorporating the qualitative and quantitative data into the evaluation of tourists' preference heterogeneity and demographics [57,59,64,65] would help the policy maker and program manager to create target segmentation strategies to create reef impact reduction program.…”

“…The purpose of an impact reduction program for reef management includes institutional management and recreational control [12,16,38,47,55,56]. The carrying capacity is one of the most important aspect of institutional management in coastal or marine areas, and in cases of reefs this often refers to the number of scuba divers and snorkelers who can be supported consistently without any degradation [19], as well as a reference point for ensuring that these and other forms of experience-based tourism will have a minimum impact on the natural and environmental resources in protected areas [38].…”

“…All of the above stakeholders were working in Taiwan at the time. According to the opinions garnered from the FGDs and our literature review, this study chose the following six attributes of a potential reef impact reduction program: (1) Set up control of the number of divers [38,55,57]; (2) set up control of the experience area [40,56]; (3) the way to the snorkeling site [11,12,45]; (4) education training [8,11,47]; (5) marine police [41][42][43][44]; (6) willingness to pay [3,21,29]. The tourist's preferences for attributes and levels of a potential reef impact reduction program are shown in Table 1.…”

The act of balancing two sustainability goals, the conservation of ecosystem services, and allowing access to reef recreational areas is a big challenge for the management of marine protected areas (MPAs). This study evaluates tourist preferences towards integrative aspects of an impact reduction program in a reef recreation area. We find that by integrating the marine police institution, providing educational training, setting up control of the number of divers, setting up control of the experience area, and taking boats to the snorkeling point are the key factors. We also identify the features that affect the heterogeneity of preferences with impact reduction management in the MPAs as follows: (1) monthly income; (2) type of tourist; and (3) joining conservation groups, and the integrated program generate the highest welfare value. These results can be applied to create a suitable management strategy for sustainable reef tourism that meets the needs of stakeholders.

“…Rầt nhiều nghiên cứu [2][3][4][5][6] về khả năng tiếp nhận và sức tải môi trường được thực hiện trong những năm gần đây ở Trung Quốc cho ta thấy các nước đang phát triển (trong đó có Việt Nam) đang và sẽ phải đối mặt với các vấn đề môi trường. Enhui và nnk., (2013) [2] đã tính toán 3 phương án để giảm thiểu nồng độ phosphat trong nước vịnh Hạ Môn (Trung Quốc) từ 0,06 mg/l xuống mức tiêu chuẩn quốc gia là 0,03 mg/l, trong đó chủ yếu dựa trên việc giảm 67-74% tải lượng thải và phân bổ lại lượng thải của 22 nguồn thải đổ vào vịnh. Tại vịnh Jinzhou (Trung Quốc), khả năng tiếp nhận của Zn và Cd xấp xỉ là 17 và 8 tấn/tháng và tổng tải lượng thải tối đa (TMAL -Total Maximum Allocated Loads) được phân bổ của Zn và Cd là 4 và 1,7 tấn/tháng [3].…”

Dựa trên các số liệu khảo sát về chất lượng nước tại đầm Thị Nại mùa mưa (tháng 10/2013) và mùa khô (tháng 5/2014), các tài liệu thu thập về điều kiện tự nhiên, kinh tế - xã hội ven đầm và các tiêu chuẩn môi trường, đã tính toán khả năng tiếp nhận các chất ô nhiễm trong đầm thông qua sử dụng mô hình Delft3D. Kết quả tính cho thấy, hiện tại đầm Thị Nại không còn khả năng tiếp nhận amoni, nitrat. Tới năm 2025, ngoài 2 thông số này đầm Thị Nại sẽ không còn khả năng tiếp nhận phosphat. Ngoài ra, khả năng tiếp nhận của đầm sẽ giảm đi đối với hầu hết các thông số (3,44%, 1,84%, 0,02%, 12,18%, 0,46% đối với COD, Cu, Pb, Zn và As, tương ứng), trong khi khả năng tiếp nhận BOD5 và vật lơ lửng tăng lên. Liên quan đến các kim loại nặng, khả năng tiếp nhận của đầm cũng giảm đi nhiều nhất là Zn (12,18%).

Economic activities are constantly increasing in the southern key economic region (SKER), especially in Ho Chi Minh City (HCMC), which leads to the influx of large amounts of wastewater from this region into Ganh Rai Bay (GRB). The problem of assessing the marine environmental carrying capacity (MECC) of coastal areas is urgent, and the role of self-cleaning must be elucidated. Four typical pollution parameters were selected: ammonium (NH4 + ), biological oxygen demand (BOD), phosphate (PO4 3-), and coliforms. The study aims to propose a framework to assess the impact of the role of self-cleaning on MECC and to apply the proposed framework to GRB as a case study. A series of models were used to simulate hydrodynamics, and an advection-diffusion model with an ecological parameter set was used for water quality modelling. The land-ocean interactions in the coastal zone model were used to calculate the GRB and East Sea retention time.Finally, a multiple linear regression model was used to clarify the relationship between the MECC and self-cleaning factors. Calculation results show that the self-cleaning factor increased the MECCAmmonium by 60.30% in the dry season and 22.75% in the wet season; similar to MECCBOD, MECCPhosphate increased by 5.26%, 0.21% (dry season), and 11.04%, 0.72% (wet season), respectively. MECCCColiforms in the dry season increased by 14.83%; in the wet season, MECCColiforms doubled. The results provide medium-and long-term solutions to improve the water quality of the GRB, especially the selection of activities that conserve the ecological system and improve the self-cleaning capacity of the bay.
