Paul Adams in Ukraine after the latest ceasefire - even if the fighting stops for good, what will peace look like for those who survived? And Andrew Harding in Liberia finds that after the distrust and fear caused by ebola, life is returning back to normal for some - like those playing football.

In Colombia, Rosie Goldsmith meets writers who are hopeful for their country's future, if it can achieve peace with the leftist rebels. They think this is the make-or-break year. And in Argentina, Chris Haslam travels through the mountains for four days to reach a septuagenarian llama farmer whose house is so isolated, that it's a 36-km round trip trek over a treacherous mountain pass to get to his animals "in the meadow, round the back". Does he get lonely? No, he has visitors all the time, the last one was there "just eight weeks ago".
