“…If conceding water area for co-management is considered a payment, these fishers are not willing to pay but want to receive subsidies and social incentives to participate in the process. This result confirms Phong, Thang, and Hoai's [61] research which indicated that Vietnamese farmers are unwilling to pay for good aquaculture practices but requested a subsidy to treat wastewater using biological processes. Furthermore, this result seems to demonstrate a lack of trust and loss of faith between individual fishers and fishers' associations' leaders in one part and towards fishery authorities in the second part, as noted in southeast Benin by Sonneveld [22].…”

“…LCL uses a statistical methodology based on the concept of likelihood to identify the sources of heterogeneity at the segment level rather than the individual level, similar to the MXL model [79]. This model is increasingly applied in recent segmentation studies and generates good results [61,75,80].…”

“…They found that farmers are willing to trade-off the size of the subsidy for less restrictive scheme requirements. Phong, Tang, and Hoai [61] used a DCE to identify what motivates farmers to accept good aquaculture practices in development policy. They found that increasing the adoption of good aquaculture practices in Vietnam needs other support policies, such as aquaculture insurance provision, subsidies for wastewater treatment, and compliance with regulations on antibiotic use.…”

The estuarian and lagoon areas of southeast Benin are atypical lake territories where private property rights are hereditary from endogenous legal tradition. People live in stilt dwellings and are exclusively dedicated to free-to-access fishing. Consequently, an increasing number of fishers with low respect for the State’s general rules for sustainable fishing contribute to legal pluralism and the tragedy of the commons. Co-management of small-scale fisheries has been advocated to offer various benefits, including improved socio-ecological integration, shared sustainable livelihoods, and adherence to biodiversity objectives. This study aims to assess the factors that influence the willingness of small-scale fishers to adopt property rights co-management options in southeast Benin. The data were collected using the discrete choice experiment method. The results show that 44% of fishers are willing to adopt property rights co-management options. This willingness is determined by their involvement in the co-management committee, access to a subsidy and livelihood diversification options. These fishers are the oldest in the sample and primarily owners of Acadja, a traditional fishing tool made of bush and tree branches planted in the lake. Institutional agreements for co-management establishment, such as subsidies to support small-scale fishers’ livelihood diversification and capacity-building, must be set up to achieve co-management goals.

“…Indeed, wastewater from the aquaculture industry was often drained without proper treatment, leading to severe problems in the nearby water environment and odor pollution due to the decomposition of organic matter [3,4]. Noticeably, wastewater from seafood manufacturing contains a high concentration of dissolved organic carbonaceous compounds such as biochemical oxygen demand (BOD) and chemical oxygen demand (COD) as well as nutrients including nitrogen and phosphorus [5][6][7]. These substances cause harmful algal blooms and damage the natural aquatic ecosystem [8].…”

In this work, seafood wastewater was treated by using MBBR reactor over a novel carrier (PUF-PVA gel) derived from the combination of a porous (PUF) and hydrophilic surface (PVA gel). A freezing-thawing method was used for the preparation of the novel PUF-PVA gel which is reported for the first time. Experimental results indicated that PUF-PVA gel carrier which possesses an excellent textural structure (specific surface area of 3.4 m2/g, pore size in the range of 10 -40 μm and hydrophilic surface) accounts for faster water immersion and better microbial adhesion, resulting in the biofilm content attached at the start-up stage 2.4 times higher relative to conventional PUF carrier alone. The MBBR system can be operated stably at a hydraulic retention time (HRT) of 7 hours in which the organic loading rate ranged from 2.5 kg COD/m3.day to 5.1 kg COD/m3.day. When operated at the organic loading rate of 2.5 kg COD/m3.day, the maximum COD and the nitrogen removal efficiency of MBBR based on the PUF-PVA gel carrier were 92 ± 0.6% and 89 ± 3.4%, respectively, which is higher than that of the PUF carrier.

Without you, this thesis would not have been possible.Thank you to the individuals and their organizations in Vietnam that opened their arms for me and helped me organize my field work. I would like to thank the ICAFIS, WWF Vietnam, as well as Department of Agriculture and Rural Development in Mekong Delta for facilitating access to the farmers
