issues in the Province, as well as monitoring and evaluation". Each province is headed by a governor, appointed by the president and approved by the Senate. The districts are responsible for coordinating public service delivery and economic development. They are divided into sectors, which are responsible for the delivery of public services as mandated by the districts. Districts and sectors have directly elected councils, and are run by an executive committee selected by that council. The cells and villages are the smallest political units, providing a link between the people and the sectors. All adult resident citizens are members of their local cell council, from which an executive committee is elected. The city of Kigali is a provincial-level authority, which coordinates urban planning within the city. Geography At , Rwanda is the world's 149th-largest country, and the fourth smallest on the African mainland after Gambia, Eswatini, and Djibouti. It is comparable in size to Burundi, Haiti and Albania. The entire country is at a high altitude: the lowest point is the Rusizi River at above sea level. Rwanda is located in Central/Eastern Africa, and is bordered by the Democratic Republic of the Congo to the west, Uganda to the north, Tanzania to the east, and Burundi to the south. It lies a few degrees south of the equator and is landlocked. The capital, Kigali, is located near the centre of Rwanda. The watershed between the major Congo and Nile drainage basins runs from north to south through Rwanda, with around 80% of the country's area draining into the Nile and 20% into the Congo via the Rusizi River and Lake Tanganyika. The country's longest river is the Nyabarongo, which rises in the south-west, flows north, east, and southeast before merging with the Ruvubu to form the Kagera; the Kagera then flows due north along the eastern border with Tanzania. The Nyabarongo-Kagera eventually drains into Lake Victoria, and its source in Nyungwe Forest is a contender for the as-yet undetermined overall source of the Nile. Rwanda has many lakes, the largest being Lake Kivu. This lake occupies the floor of the Albertine Rift along most of the length of Rwanda's western border, and with a maximum depth of , it is one of the twenty deepest lakes in the world. Other sizeable lakes include Burera, Ruhondo, Muhazi, Rweru, and Ihema, the last being the largest of a string of lakes in
