The Africa Region's Indigenous Knowledge for Development Program promotes client/staff action learning through cross regional exchanges to learn about the impact of Indigenous Knowledge (IK) systems in development. The first such exchange and learning tour was organized in September-October 2002 between three East African countries (Ethiopia, Kenya and Uganda) and two South Asian countries (Sri Lanka and India). The exchange involved several innovative features which are highlighted here. The learning exchange included 16 development practitioners from Ethiopia, Kenya, Uganda (i.e., project staff from Bank-supported projects in early childhood development and medicinal plant projects, civil society representatives, a traditional healer, a parliamentarian and a minister) accompanied by 5 Bank staff working on these projects. The group visited counterparts in Sri Lanka and India, including projects using informatics for social sector development.
