I think the following should be mentioned: Roland Arnold Young and
Henry Fosbrooke, *Smoke in the Hills: political tension in the
Morogoro District of Tanganyika* (Evanston: Northwestern U. Press,
1960)
This is a singularly inept title. The book is in fact about violent
and other resistance to terracing and other conservation measures in
Morogoro. I remember the introductory chapter talking about
conservation measures in eastern Africa in general.
