Synopses & Reviews

Protecting rivers and vital ecosystems as the world aims to feed 8 billion people will require a doubling of water productivity — getting twice as much benefit from each gallon removed from rivers, lakes, and aquifers. points the way toward managing the growing competition for scarce water.
