What are we trying to do?Build a database of the world's dams (especially for protected areas)
Why?Dams are critical to water supply and energy generation in many countries yet :
- There is no definitive spatial database of dams.
- We cannot measure or model the impact of land use and climate change on water supply to dams without such a database
- Dams are the point at which intangible water based environmental services become tangible and they are this potentially critical in financing upstream watershed management and conservation.
How can you help?Spend a few hours looking closely at an area of your choice in Google Earth and use the built-in Geowiki to digitise the dams for that area.
