Under appropriate conditions, all of these forms of decentralization can play important roles in broadening participation in political, economic and social activities in developing countries. Where it works effectively, decentralization helps alleviate the bottlenecks in decision making that are often caused by central government planning and control of important economic and social activities. Decentralization can help cut complex bureaucratic procedures and it can increase government officials' sensitivity to local conditions and needs. Moreover, decentralization can help national government ministries reach larger numbers of local areas with services; allow greater political representation for diverse political, ethnic, religious, and cultural groups in decision-making; and relieve top managers in central ministries of "routine" tasks to concentrate on policy. In some countries, decentralization may create a geographical focus at the local level for coordinating national, state, provincial, district, and local programs more effectively and can provide better opportunities for participation by local residents in decision making. Decentralization may lead to more creative, innovative and responsive programs by allowing local "experimentation." It can also increase political stability and national unity by allowing citizens to better control public programs at the local level.
