This article addresses the extent to which information and communication technologies (ICTs) may be used to manage agricultural indigenous knowledge (IK) to alleviate extreme poverty and halve hunger in the rural areas of Tanzania. It also discusses ways that ICTs can be used to introduce exogenous knowledge into the local communities in order to reduce hunger and poverty. The advent of ICTs provides a window of opportunity for developing countries to harness and utilize IK to their advantage. Access to, and use of, ICTs provides new and faster ways of delivering and accessing information and knowledge that may improve productivity in a wide range of sectors, including agriculture. Access to information and knowledge may give Tanzania the possibility to reduce poverty and increase agricultural productivity. The rural population of Tanzania is not only deprived from accessing global knowledge on agriculture, but it also lacks opportunities to share its own IK. Research shows that the use of exogenous knowledge together with IK systems may improve farming activities. Recommendations are given on how IK may be effectively managed through ICTs in Tanzania
