After 1992, bold decentralization of local governance took place in
Uganda. Uganda was one of Africa’s fastest-decentralizing countries, and
community participation was at the center of reform. As participation-based
local governance is considered important throughout decentralization reform,
it is necessary to identify the determinants of community participation by
examining the social relations among residents, local government, and
community organizations. This study defines the types of social capital,
validates the measurement scales, and analyzes the effect of the types on
participation in Uganda. For empirical analysis, Afrobarometer Round 8 data
are used. Regression analysis and Structural Equation Model estimation are
conducted on a total of 964 samples of Ugandan residents. The results show
that network capital was predictive of both types of community participation
and contact with institutions is a mediator of institutional trust. Based on the
results, theoretical and practical implications for improving Uganda’s local
community participation are derived.
