Why silt is so important for the Mekong

Just as forests are more than only trees, rivers are more than water. The Mekong river carries massive loads of sediment and nutrients from upstream to downstream and across national borders, replenishing and enriching the land as it goes. This process is key to sustaining the ecological integrity of the river and surrounding landscapes, which in turn supports the economy.

However, a boom in sand mining and hydropower development on the Mekong is transforming the river’s sediment flows, with profound consequences for the region if left unchecked. For a prosperous, sustainable future for the region, all Mekong countries must come together now and adopt international standards for managing transboundary river resources.
