The Three Gorges Dam: an ecological perspective
development throughout the world for thousands of years, providing water, controlling floods, irrigating crops, facilitating navigation, creating recreational opportunities, and generating motive power and electricity. By the end of the 20th century, about 45 000 large dams (>15 m in height) and an estimated 800 000 small dams had been built worldwide (WCD 2000), obstructing over 65% of fresh w...

THE HUGE THREE-GORGES DAM (TGD) OF THE Yangtze River is going to demonstrate the mighty power of humanity to change and fragment an area of about 58,000 km2 with the formation of a huge reservoir of 1080 km2. It is expected to exert disastrous influences on many terrestrial plants and animals, as discussed by J. Wu et al. in their Policy Forum “Three-Gorges Dam— experiment in habitat fragmentat...
متن کاملEcology. Three-Gorges Dam--experiment in habitat fragmentation?
Habitat fragmentation is the primary cause of the loss of biodiversity and ecosystem services, but its underlying processes and mechanisms remain poorly understood. Studies of islands and insular terrestrial habitats are essential for improving our understanding of habitat fragmentation. We argue that the Three-Gorges Dam, the largest that humans have ever created, presents a unique grand-scale...
متن کاملThree Gorges project: chance and challenge.
THE THREE GORGES DAM (TGD) ACROSS THE Yangtze River is the world’s largest hydroelectric dam (1). Construction of the TGD will form many different sizes of islands, providing a golden opportunity for exploring the ways in which island ecosystems are regulated (1). However, the construction will also pose great challenges to the ecosystem of the Three Gorges Reservoir Area (TGRA). It will affect...
متن کاملTHE WHOLE DAM STORY: A Review of the China Yangtze Three Gorges Dam
Some marvel at these massive structures as engineering wonders that provide inestimable public benefit – things like flood control, water supply, hydroelectric power, improved navigation and water recreation. Yet others don’t share this appreciation and have doubts about the ability of humankind to effectively harness nature, particularly the power of the world’s mighty rivers. They decry the d...
