It’s one of the Earth’s most precious resources – it covers more than 71 per cent of the planet’s surface yet water sustainability is an issue of much debate, especially in the Okanagan.

Anna Warwick Sears, executive director of the Okanagan Basin Water Board, will address many issues surrounding water at a public presentation at Okanagan College’s Kalamalka campus Sept. 27 at 7:30 p.m.

Warwick Sears received a PhD in population biology at the University of California, where she studied the competition for resources in arid environments.

Before coming to the Okanagan in 2006, she was the research director of an environmental non-profit in California, leading watershed restoration and planning initiatives.

Warwick Sears is particularly interested in using science to solve real-world problems and to build bridges with community stakeholders.

Admission is $5 in advance or $7 at the door.
