Adapting food systems to climate change: lessons from aquaculture in the Vietnamese Mekong Delta
The Mekong Delta, Vietnam’s “rice bowl” and a globally significant biodiversity hotspot, is on the front line of climate change.

Rising sea levels, saltwater intrusion, and extreme weather events pose an existential threat to its ecosystems and the livelihoods of its 20 million inhabitants. Aquaculture, a cornerstone of the region’s economy and food supply, is particularly vulnerable to these changes.

This presentation will explore the evolution of climate adaptation strategies in the Delta’s aquaculture sector. Drawing on a unique longitudinal dataset, Dr Dao Minh Hai will compare comprehensive surveys of 200 shrimp farms conducted in 2011 and 2024. This decade-long analysis reveals critical trends in how farming systems, environmental impacts, and farmer decision-making have shifted in response to mounting climate pressures.

The talk will examine the effectiveness of key interventions, from integrated mangrove-shrimp and rotational rice-shrimp systems to advances in genetic selective breeding programs for enhanced salinity tolerance in species like striped catfish. By analysing what has worked and what has not, the talk will distil key lessons for building resilient aquatic food systems. These insights are essential for developing scientifically sound and practically implementable policies to safeguard food security in the Mekong Delta and other vulnerable coastal regions worldwide.
