Vietnam, with its extensive 3,260 km coastline, is among the most climate-vulnerable countries in Southeast Asia, making coastal bioshields a critical component of its national coastal protection strategy. This chapter provides a comprehensive national perspective on the development, implementation, and management of bioshields in Vietnam. It traces the historical evolution of mangrove rehabilitation, coastal afforestation, and community-based protection programs since the 1980s, highlighting their integration into broader frameworks such as the National Target Program on Climate Change, the National Strategy for Natural Disaster Prevention, and coastal zone management policies. The chapter examines key ecological and socio-economic outcomes of bioshield projects, emphasizing their dual role in shoreline stabilization and livelihood enhancement through aquaculture, fisheries, and ecotourism in Vietnam. It also discusses regional differences in bioshield performance—particularly among the Mekong Delta, Central Coast, and Northern estuaries—driven by hydrological variability and land-use pressures. Institutional challenges, including fragmented management, limited financing, and land tenure conflicts, are analyzed alongside emerging policy innovations such as payment for ecosystem services (PES) and blue carbon initiatives. Drawing on national reports and scientific studies, the chapter concludes that while Vietnam’s bioshield programs have achieved measurable ecological and social benefits, their long-term sustainability depends on strengthening governance coherence, scientific monitoring, and community stewardship. Vietnam’s experience thus offers a valuable model for other developing coastal nations seeking to integrate bioshields into climate adaptation and sustainable development frameworks.
