We've developed tools to help businesses identify their water risks and opportunities, and get involved in water stewardship. We set up the Yangtze Basin Protected Area Network in ,offering training, workshops, research, and funding opportunities. Business, communities and ecosystems are exposed to the same water challenges. That's why we see business as a key ally in helping us find solutions through water stewardship.
We're working with communities, governments and businesses across the world to promote joined-up approaches to water management. There are around 50, large dams currently in operation and millions of smaller ones throughout the world. We're working to make sure dams are carefully planned and managed so their negative impact is reduced. Discover our series of books that bring together experiences and lessons from around the globe on how to better plan and manage our precious water resources.

The picture to the left features one of the so-called "Three Gorges," dangerous to navigate because of its currents and shallows, but of incredible beauty.
A bird's eye view of the Yangtze river source Lake Dongting is the second largest lake in China. It lies in a basin in northern Hunan province to the south of the Yangtze River and is connected to the river. Lake Dongting source. In the middle and lower regions of the river, most of the precipitation falls as rain, particularly during the warm summer monsoons.
In the mountainous areas, precipitation is primarily snow. The river volume fluctuates widely, depending on the time of year and the section of the river. Upstream, the average flow is about 70, cubic feet 1, cubic meters per second, according to Encyclopaedia Britannica.
Farther downstream, as more tributaries join the primary stream, the volume gradually increases. Before the completion of the Three Gorges Dam, water volume in the Yangtze was about , cubic feet 15, cubic meters at the end of the Three Gorges region and up to 1,, cubic feet 31, cubic meters at its mouth, according to Encyclopaedia Britannica.
These numbers have decreased somewhat due to the dam. The suspended sediment load sediment that is carried in the water flow and never quite settles on the bottom at the mouth of the river is about million tons a year — one of the highest sediment loads of any river on earth.
The Yangtze River basin, an area covering million acres, is one of the most biodiverse regions on Earth — from towering mountains and thick forests to marshy wetlands and waterways, according to the World Wildlife Fund WWF. The region is home to more than species of mammals, species of amphibians, species of reptiles and species of fish, according to WWF.
Species of fish include the yellow head catfish, carp, copper fish, Chinese shad, eel, anchovies and the Chinese puffer fish, according to YangtzeRiver. Statuses range from vulnerable high risk of endangerment in the wild to endangered high risk of extinction in the wild to critically endangered extremely high risk of extinction in the wild.
The giant panda , which was recently moved from the endangered list to the slightly better status of vulnerable , lives in the bamboo forests of the Upper Yangtze region.
Although the giant panda has no natural predators, human activity has led to only a little more than 1, in the wild, according to WWF. The Yangtze River is also home to the vulnerable finless porpoise. Only about 1, of them exist in the wild. Their troubles stem from dwindling sources of food and human activity, including boat traffic. These rare porpoises live mainly in the middle and lower reaches of the Yangtze River. The critically endangered Chinese alligator , which numbers only around in the wild, also lives in the lower regions of the river and its surrounding lakes.
