Introduction
Rice–Fish Farming has emerged as a significant integrated agricultural practice within the Hau Giang Province of the Mekong Delta, offering a sustainable alternative to monoculture rice production. This topic introduces the ecological, economic, and social relevance of the system, outlining how combining rice cultivation with aquaculture enhances biodiversity, soil fertility, and farmer income. It also establishes the need to examine both drivers and barriers influencing its adoption among local farmers to improve long-term sustainability and regional resilience.
Socio-Economic Drivers Influencing Adoption
This topic explores how factors such as household income levels, market access, labor availability, and financial stability motivate farmers to shift toward Rice–Fish Farming. Economic incentives, including higher profit margins and diversified income streams, act as strong drivers. The discussion also highlights the role of community networks, extension services, and local government support that encourage adoption among smallholder farmers in Hau Giang Province.
Environmental and Agronomic Benefits as Drivers
This paragraph examines environmental advantages that encourage farmers to implement Rice–Fish systems. Benefits such as improved soil quality, reduced pest populations, lower dependency on chemical fertilizers, and enhanced water productivity are analyzed. These ecosystem services strengthen the sustainability of rice fields and provide long-term resilience to climate variability, proving to be important motivators for adopting integrated farming practices.
Institutional and Technical Barriers to Adoption
This research topic analyzes structural and technical constraints that prevent wider adoption. Limited access to technical knowledge, inadequate extension services, and insufficient training programs pose major obstacles. The lack of infrastructure, such as proper water management systems, and the limited availability of high-quality fish fingerlings also restrict the scalability of Rice–Fish Farming in the Mekong Delta.
Economic and Market-Related Barriers
This paragraph discusses financial and market limitations that hinder adoption. High initial investment costs, fluctuating fish prices, and unpredictable market demand can discourage farmers. The topic also explores the risks associated with crop–fish interactions, potential yield losses, and the challenges farmers face when attempting to access profitable value chains for both rice and fish products.
Policy Recommendations and Future Research Needs
The final topic proposes strategic interventions to address adoption challenges and enhance system sustainability. It emphasizes the need for supportive policies, farmer training programs, and investments in rural infrastructure. Additionally, future research directions are suggested, including long-term ecological monitoring, cost–benefit analyses, and the development of climate-resilient Rice–Fish models tailored specifically to the Hau Giang Province.
