Efficiency of Different Integrated Agriculture Aquaculture Systems in the Red River Delta of Vietnam

Nguyen Van Huong*, Tran Huu Cuong, Tran Thi Nang Thu and Philippe Lebailly

Freshwater aquaculture production systems are closely related to Integrated Agriculture Aquaculture systems (IAA). Four systems were identified from freshwater aquaculture farming in the Red River Delta of Vietnam. There was prevalently VAC system existence both inside and outside the residential area. The system was defined as farming diversifications and nutrient linkages among V (orchard), A (pond) and C (animal) components relying on the on-farm resources and off-farm integrations and linkages with other human activities. The development of the freshwater aquaculture systems was very diverse and dynamic.

The paper presented the economic efficiency and effectiveness on four freshwater fish production systems. Clear evidence was found to provide evidence that the traditional VAC system was sustainable food supply model for the developing countries. Farms operated the VAC systems could easily diversify their farming activities, foods, foodstuffs, redundant employment, and income. Especially, income diversification was a practical strategy for rural farms to reduce the vulnerability on their agricultural practices both on production and market risks. The advantages were likely to ensure that VAC systems would still be more and more important role in northern Vietnam for food security and rural development under the context of agricultural land loss by transforming progressively into urbanisation and industrialisation.
