It's a real pleasure to have Briton Hannah Matthews on the show once again and see how far she's come in Colombia. It seems like only a few weeks ago that we had her on the show talking about what it was like to teach English as a foreigner in Colombia. 

Now, she's in the Peace Brigades International and has spent a great deal of time in some of Colombia's most conflicted regions working to preserve human rights. 

As an international observer for PBI Colombia Hannah has had the opportunity to gain experience in the field of international human rights. She has worked in Bogotá, Barrancabermeja and Urabá, accompanying human rights defenders and communities who are being threatened because of their legitimate work in support of justice and peace.

Against a backdrop of political unease in Colombia and the presidential elections of 2018, this is an important and timely interview.

It's a brave man who sets out his stall to bring high school trips to Colombia, but, British travel writer Simon Willis has done just this with his outfit, Kagumu Adventures (www.kagumuadventures.com). 

Fresh off the trail from leading a bunch of eager students from an international school in Chile, who he took out to rural Antioquia and in to the infamous Comuna 13 in Medellin, Willis understands that tourism can be a create positive change in Colombia and indeed fulfill some of the Millennium Development Goals. 

Tune in to hear an inspirational tale of how a guy with an idea - albeit a brave one - can bring about change.

Sometimes it's hard to be an international transplant to a small community in Colombia, but briton Matty Sowinski Brown has successfully become an accepted resident in the charming town of Quimbaya in Colombia's coffee region. 

So, this week on Episode 211 of Colombia Calling we get on the line with Matty in Quimbaya (Quindio) to talk about his life there, the rural guesthouse he is opening up soon named "Cascada Blanca", and the delights of a traditional christmas - lanterns and all - in which he is participating this year in his new home town.
