I recently went to the refugee camp in Calais with a group of students from Oxford. We had collected food and clothes to take over and had raised a lot of money.
We spent several days helping out at a warehouse and distributing donations, as well as talking to refugees there, hearing their stories and working out how best to spend the money and how we could raise awareness of the situation in the camp.
I have written two pieces in response to my visit. One describes the camp: https://collect4calais.wordpress.com/2016/03/27/a-picture-of-calais-sophie-dowle
The other looks at how the camp illustrates the number of unremembered conflicts there are: http://www.cherwell.org/comment/world/2016/03/26/calais-the-camp-of-forgotten-conflicts
