Glen Ellen photographer Jane Baldwin has spent a decade traveling through the Omo River Valley in Ethiopia, documenting the lives of tribal women, as shown her current Sonoma Valley Museum of Art exhibit -- “Kara Women Speak.”

The exhibit, which includes audio interviews with the women and video of Baldwin’s work with them, offers an opportunity for a serious discussion of their environment.

The massive Gibe III hydro-electric dam, which becomes active this month, is seen by environmentalists as a threat to the Omo River Valley’s ecosystem.

The museum will present a panel discussion titled “Pinching the Lifeline,” moderated by David Bolling with the photographer Baldwin participating, from 4 to 6 p.m. Saturday, Oct. 17. The panel will include Anuradha Mittal, founder and executive director of the Oakland Institute; Muadi Mekenge, program director of the Global Fund for Women for sub-Saharan Africa, and Stephen Corry, director general for Survival International.

Admission: $10 for Sonoma Valley Museum of Art members; $15 for the general public. Registration is limited. Register at svma.org/calendar.
