Abstract

This study analyzed the determinants and potential impacts of the adoption of sustainable aquaculture (SA) technologies on the welfare of small-scale aquaculture (SSA) households in Myanmar using an endogenous switching regression model. Welfare is measured by fish productivity and fish income per cycle and Household Dietary Diversity Score. Our analysis revealed that distance to the sale-point, membership in farmers’ organizations, awareness of pond maintenance benefits, access to information through private extension services, and location were the main drivers behind adopting SA technologies. Results showed that adopting SA technologies increases welfare outcomes of SSA households; however, the non-adopters stand to benefit the most in terms of an increase in welfare outcomes if they adopt the technologies. Our research findings suggested that policies targeted at raising SSA households’ income and dietary diversity can be realized through interventions to raise farmer’s awareness, adoption, and technical know-how about the SA technologies.

摘要

本研究使用内生转换回归模型分析了采用可持续水产养殖 (SA) 技术对缅甸小规模水产养殖 (SSA) 家庭福利的决定因素和潜在影响。福利通过鱼类生产力和每个周期的鱼类收入以及家庭膳食多样性得分来衡量。我们的分析表明，与销售点的距离、农民组织的成员身份、对池塘维护效益的认识、通过私人推广服务获取信息以及位置是采用 SA 技术的主要驱动力。结果表明，采用 SA 技术可提高 SSA 家庭的福利成果；然而，如果非采纳者采纳了这些技术，他们将在福利结果的增加方面受益最大。
