Dynamics and Determinants of Participation in Integrated Aquaculture–Agriculture Value Chain: Evidence from a Panel Data Analysis of Indigenous Smallholders in Bangladesh
利用孟加拉国原住民小农的三轮面板数据，研究了综合水产养殖-农业价值链参与的动态，发现教育、家庭规模、推广服务、市场信息和社区组织促进参与，而农场规模和收入不影响持续参与，表明该模式适合资源贫乏农户。
This study examines the dynamics of integrated aquaculture-agriculture (IAA) value chain participation and assess the determinants of participation (non-participators, continuing participators, and leavers) using three wave panel data obtained from small-scale indigenous farm households in Northern and North-eastern region of Bangladesh. We employ panel estimation strategies to control for omitted variables and endogenous regressors. The results confirm some previous findings that educated, larger family size with better access to extension, market information and community-based organisation (CBO) are more likely to participate and continue in IAA value chain activities. Importantly, farm size and farm income does not matters for IAA value chain continuous participation, suggesting that IAA value chain activities are appropriate for resource-poor households who are only able to afford low-input technology. The results also indicate that the factors influencing continued participation and dis-participation of the IAA value chain activities especially for up and downstream activities are different.
