A new study shows a third of the biggest aquifers in the world are being depleted as more water is being drawn, than is being replenished.  The research from NASA satellites shows that 21 of the world's 37 largest aquifers are at risk of drying up.

Sasha Richey from NASA's Jet Propulsion Laboratory is one of the authors of the study.

10:05 Citizens rising up against the cartels

For his film Cartel Land, Matthew Heineman embedded himself with a citizen-led paramilitary group in the Mexican state Michoacán, lead by former California physician Dr Jose Mireles. The group was set up in 2013 to counter the violence of the local drug cartel, The Knights Templar, which provides methamphetamine to the US and have been responsible for kidnappings and massacres in the state. Matthew Heineman also spent time with another armed vigilante group, this time on the other side of the Rio Grande. Arizona Border Recon patrols the state's Altar Valley, which is known as Cocaine Alley. He says making the film was a terrifying experience and talks to Kathryn Ryan about the film and how the lines between good and evil are blurred in the dangerous world of cartels on the Mexican border.

Cartel Land screens at the New Zealand International Film Festival which starts in July. You can view the trailer on YouTube.

11:20 Hat's Lessons on Life

Harriet “Hat” Rowland is the author of the bestselling The Book of Hat, a finalist in this year’s NZ Book Awards for Children and Young Adults. Hat died last year, aged 20, two years after she was diagnosed with osteosarcoma – a rare form of bone cancer. The Book of Hat is a collection of her blog posts, written after her diagnosis, throughout her grueling treatment, brief remission, then devastating relapse.

Book Awards judging panel convenor Bob Docherty says, "It's funny at times, it's melancholic at times, there's nothing pretentious about it. It's just raw living from someone who is on the edge, and it's not a tragedy. This is life."

For Hat's parents, Jan Kelly and John Rowland, the book’s shortlisting for the book awards is bitter sweet. John talks to Kathryn about what his daughter still has to teach others.
