Singer-songwriter Jann Arden and environmentalist David Suzuki will add radio hosting duties to their resumés this summer, with each debuting new weekly shows on CBC Radio.

Being Jann, an hour-long Saturday morning show featuring the Juno Award-winner spinning tunes, conducting interviews and sharing stories, is one of the new programs to be featured on the network's summer program lineup, which begins June 28.

A new addition on Sunday mornings will be The Bottom Line with David Suzuki, in which the renown broadcaster, climate change activist and host of CBC-TV's The Nature of Things talks to scientists, politicians and celebrities about environmental issues.

"We're thrilled to welcome some new faces to the radio team," Chris Boyce, programming director of CBC Radio, said in a statement.

"Jann Arden's sense of humour and rich musical background will make her an exceptional host. David Suzuki will do what he does like no one else — provoke strong opinions and debate on enviornmental issues.

Other new programming includes:

• Coverage of the FIFA World Cup 2010, including live broadasts of the last four games of the tournament, as well as the five-part drama 'Y' Soccer.
• Food-related show The Main Ingredient.
• This is That, an improv comedy program satirizing public radio.
• Asunder, a 10-part series exploring divorce in Canada.
• Promised Land, a program chronicling stories of harrowing escapes made by immigrants and refugees to arrive in Canada.

Guest hosts will take the mic for the summer editions of shows such as The Current, As It Happens, The Sunday Edition and Q.
