Adding to droughts, floods, extreme weather, and die-offs, psychologists are observing higher levels of anxiety, depression, and post-traumatic stress disorder in certain areas and professions.

The input report for this year’s World Water Week, released yesterday by the Stockholm International Water Institute, in fact argues that getting water management right is a prerequisite for sustainable development.

Obstetric fistula, a hole in the birth canal caused by obstructed labor, affects between 50,000 and 100,000 women each year, mostly in developing countries.
