Editor's note

It's summer here in the northern hemisphere, and this week The Conversation Global was thinking about travel. Our authors looked at the issue from two different angles, asking whether billions of traveller dollars actually help people in poor countries and exposing the unintended consequences of holiday tourism.

Don't miss those stories this weekend, plus coverage of Italy's forest fires, the fragile future of island nations and France's thorny alliance with the US.

And for those of you taking a break, we wish you safe (and ethical) travels!
