The country is divided into four regions—East, Central, West, and South—each administered by a governor appointed by the king. As of 2002 there were 20 districts ( dzongkhas ) under the supervision of district commissioners ( dzongdas ), who are appointed by the Royal Civil Service Commission and are responsible for law and order. Districts are further subdivided into blocks ( gewog ), of which there are 202 in the country. As part of the king's efforts to encourage decentralization in decision-making, in 1991 the government began a program to establish Block Development Committees. This project allowed people to plan and implement development projects within their respective blocks (in the 1980s, a development plan was organized for the districts). The success of the district and block development programs encouraged citizens to form other types of associations, such as school management boards, village health development committees, and associations for different agricultural products, such as apples and potatoes, for example.
