Greater Mekong
What WWF is doing
Stunning wildlife, diverse people, big challenges
The Greater Mekong contains some of the richest and most biologically diverse habitats on our planet.
Its vast forests and wetlands harbour some of the world's rarest species including Asian elephants, Indochinese tigers, Javan rhinos, Irrawaddy dolphin and the elusive Saola.At the heart of the region, is the Mekong River. Winding 4, 800 kms through six countries - China, Myanmar, Laos, Thailand, Cambodia and Vietnam - it provides habitat to an amazing diversity of fish. This includes some of the world's largest freshwater species:
- the Giant freshwater stingray (Himantura chaophraya) weighing up to 600kgs
- Mekong giant catfish (Pangasianodon gigas) weighing up to 350kg
The Mekong River basin accounts for up to 25% of the global freshwater catch, making it the world's largest inland fishery.
Today, this region is on an ambitious development path that is resulting in rapid social, economic and environmental change.
There is no doubt the Greater Mekong must develop, the question is how?

WWF Vision for the Greater Mekong
Protecting the Greater Mekong
A massive and irreversible current of change is underway.
Social and economic development is necessary to improve the lives of millions of people in the region, but if it is not planned sustainably it could also create serious and irreversible problems, particularly now in the face of climate change.Today, WWF Greater Mekong Programme is working with local communities, government partners and industry across Cambodia, Laos, Thailand and Vietnam to help conserve the rich biodiversity and natural ecosystems, upon which the region's future depends.
Our work is focused within 4 globally important ecoregions:
