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. The nationwide adult HIV prevalence is 6.2%. Areas of support include the holding of a simulation exercise in 2012 to improve coordination in response to natural disasters.

OCHA ROSA has started to cover Tanzania from May 2012 and supported the organization and conduction of simulations both in Zanzibar and Mainland Dar es salaam. OCHA ROSA also supported the UN Country Team in Zanzibar in the development of a response plan to floods.
