The Mekong Delta is one of the most productive agricultural areas in the world, though it is also the most vulnerable. Vietnam has used the “International Principles” to adapt legislation and develop its national program toward better management of shrimp farming. However, it was reported by small-scale farmers in Tra Vinh province that the Principles were difficult to apply, as they focus on ecology and ignore the adaptation and social aspects. Shrimp farmers have been experiencing declining yields and incomes, along with the continued clearance of mangroves. Vietnam has lost half of its mangrove forests over the past 30 years, notably to make way for shrimp ponds. A worrying trend, as healthy mangroves make important contributions to both climate change adaptation and mitigation, forms a natural habitat for many aquatic and terrestrial species, and provides a source of livelihood for coastal communities. To reduce the pressure on mangroves and enhance shrimp farmer livelihoods and resilience, this project supports the development and introduction of sustainable aquaculture models which coexist symbiotically with mangrove forests. This project achieves the sustainable transition of shrimp farming in Tra Vinh based on the requirements of the ASC international standard, through a detail-oriented analysis of the environmental, social, and economic conditions of the region and context-specific capacity-building methods that target relevant local stakeholders in shrimp farming.
