Most people in Ihushi belong to an ethnic group called Sukuma, which is known for its many groups and associations, focused on mutual support and collaboration for different needs. The groups are often justified by the saying "umoja ni nguvu, utengano ni udhaivu", i.e. "unity is strength, separation is weakness".
IDC has followed this tradition in the way women's groups are organised. Each group is gathered around a common activity such as growing vegetables, making batik fabrics energy-saving stoves or crocheted materials.
The group also serves as social support; being a member means being there for each other and helping out when someone needs assistance.
Each group also serves as a small cooperative bank: The members save money together and individual members will take loans and pay interest. Read more.
Today (2018), there are 13 women's groups connected to IDC with 10-20 women (and some men) in each group. IDC supports the groups with seminars, field trips, etc – according to the their needs and interests.
