Editor's note

The importance of demonstration farms was first recognised over a century ago by Seaman Knapp who believed in the philosophy of teaching by demonstration. Over the decades, governments, universities, and research institutes across the world have adopted this philosophy and set up farms to teach farmers. But as Esther Ndumi Ngumbi writes, there are far too few of them in Africa where they could unleash a revolution in her agricultural practices.  

The African Union has proposed an African passport. Uchenna Okeja sets out why he believes it could represent a new political agenda that’s worth fighting for.

The call by South Africa’s Public Protector, Busisiwe Mkhwebane, for the country to change the constitutional mandate of its central bank has the potential to cause a constitutional crisis, argues Jannie Rossouw.
