Traditional ecological knowledge is under threat in the Vietnamese Mekong Delta

Threats to Traditional Ecological Knowledge in the Vietnamese Mekong Delta

Rural communities in the Vietnamese Mekong Delta are experiencing a loss of traditional ecological knowledge due to climate change, agricultural modernization, and migration, which are reshaping local livelihoods.

Traditional ecological knowledge (TEK) is a dynamic body of knowledge that develops through experimentation, learning, and interaction with the environment, playing a crucial role in supporting resource-based livelihoods in rural communities.

TEK shapes ways of life, norms, values, and the ‘living with floods’ cultures of rural communities.

Despite its value, some argue that TEK is less relevant in the context of changing waterscapes and technological advancements in the Mekong region.

However, in the Vietnamese Mekong Delta, TEK is considered a valuable shared asset, as seen in local practices such as fish trap making, which illustrates the evolution of TEK through community interactions with water environments and everyday livelihoods.
