In this week's edition: thousands of displaced people need more aid in the Lake Chad basin, we see why Buhari's replacement has so far impressed Nigerians; and new officials in Kidal hope to bring law and order to northern Mali. There are calls for more international help for the thousands of people struggling to get by around Lake Chad after having been forced from their homes by Nigeria’s Boko Haram insurgency. We report from a refugee camp in Kolofata, Cameroon.

Also, as the president of Africa's top economy remains in London for a sixth week on sick leave, we take a look at his vice president and the positive reviews of Yemi Osinbajo's temporary stewardship of Nigeria.

And there are hopes that Kidal has taken a key step closer to delivering on a hard-won peace deal of 2015 after an interim authority for the northern Malian region is finally installed. Other regions are to follow.
