Tanzania is a low-income least developed country (LILDC). About 80% of Tanzanians live in rural areas and engage in small-scale rain-fed agriculture for the production of staple food and cash crops, as well as rearing livestock. Its nationwide adult HIV prevalence is 6.2%. As of 2014, an estimated 1.6 million people are food insecure across Tanzania.

OCHA ROSA started covering Tanzania in May 2012 and supported the organization and holding of simulation exercises both in Zanzibar and Dar-es-Salaam in 2012 to improve coordination in response to natural disasters.

OCHA ROSA also supported the UN Country Team on Zanzibar Island in the development of a response plan to floods and carried out information management review.
