Aquaculture is a risky industry among others due to exposure to weather extremes and its dependence on surrounding environment. Joint risk-sharing solutions, such as risk pooling, mutual insurance and certification programs can incentivize good risk management and eventually reduce the risk. However, such solutions are often hampered by problems of systemic risks and information asymmetry. As a consequence, insurance companies withdrew from aquaculture industry. However, the systemic nature of production risks transcending open-system farm boundaries and information asymmetry cannot be dealt with at the individual farm; instead, they require a beyond farm management approach.There are multiple beyond farm management approaches, which can be grouped broadly into economic approaches, ecosystem approaches and landscape approaches. They vary from individual approaches, starting from the farm-level to more specifically defined area or landscape approaches, which take the area-level as a starting point. To reduce the problems of systemic risks and information asymmetry, current attention focuses mostly on top-down strategies such as clusters, group certification and/or aquaculture improvement, bottom-up strategies thriving on farmers' social ties and joint responsibility to reduce risk through beyond farm management get little attention. However, the top-down nature of these various approaches forgoes to build on the existing social relations and common understanding of risks among farmers. This raises the question whether bottom-up management can lead to beyond farm approaches with higher intrinsic motivations of farmers to collaborate and thus to more effective ways of dealing with the problems of systemic risks and information asymmetry - so widely apparent in aquaculture.The purpose of this thesis is therefore to explore how beyond farm management enables to address systemic risks and information asymmetry. Three analytical dimensions are used for the exploration: socio-spatial connectivity, shared information practices and beyond farm cooperation strategies. Central to each dimension is that social relationships play a role and that there is some degree of common understanding of risks. This thesis hypothesises that more social relations and common understanding of risks reduce the problems of systemic risks and information asymmetry. Vice versa, more individualization is hypothesised to lead to higher levels of systemic risks and information asymmetry.In order to explore how beyond farm management enables to address systemic risk and information asymmetry, this thesis uses various quantitative and qualitative methods to collect and analyse data.Chapter 2 develops a socio-spatial index (SSI) that enables the objective definition of areabased management based on the spatial extent of the social connectivity of shrimp farmers. The chapter explores how the SSI translates into individual and shared risk behaviour by using structural equation modelling. Data for chapter 2 is collected through a structured farmer survey, which was carried out from November to December 2018 in Ca Mau, Bac Lieu and Soc Trang in Vietnam; the main shrimp producing provinces in the Mekong Delta. Four production systems were included in the sample: intensive shrimp system, semi-intensive shrimp system, improved extensive shrimp and integrated mangrove - shrimp system. This chapter used a structural equation model (SEM) as a technique which allows to identify relationships among endogenous and exogenous variables.
