full_context: Document 1: Republic of the Congo: Economic reform efforts continued with the support of international organizations, notably the World Bank and the International Monetary Fund. The reform program came to a halt in June 1997 when civil war erupted. When Sassou Nguesso returned to power at the end of the war in October 1997, he publicly expressed interest in moving forward on economic reforms and privatization and in renewing cooperation with international financial institutions. However, economic progress was badly hurt by slumping oil prices and the resumption of armed conflict in December 1998, which worsened the republic's budget deficit.
Document 2: Republic of the Congo: According to CIA World Factbook, the people of Republic of the Congo are largely a mix of Catholics (33.1%), Awakening Lutherans (22.3%) and other Protestants (19.9%). Followers of Islam make up 1.6%, and this is primarily due to an influx of foreign workers into the urban centers.
Document 3: Lake Chilwa: Lake Chilwa is the second-largest lake in Malawi after Lake Malawi. It is in eastern Zomba District, near the border with Mozambique.

Congo-Brazzaville was formerly part of the French colony of Equatorial Africa. Upon independence in 1960, the former colony of French Congo became the Republic of the Congo.

Document 5: Lealui: Lealui or Lialui is the dry season residence on the Barotse Floodplain of the Litunga, king of the Lozi people of western Zambia. It is located about 14 km west of the town of Mongu and about 10 km east of the river's main channel. At the end of the rainy season, generally in March as the Upper Zambezi flood waters encroach on the compound, the Litunga moves to Limulunga on higher ground. The move is celebrated in the Kuomboka festival, one of Zambia's most important and popular.
Document 6: Tellico Reservoir: Tellico Reservoir, also known as Tellico Lake, is a reservoir in Tennessee, created by the Tennessee Valley Authority (TVA) in 1979 upon the completion of Tellico Dam. The dam impounds the Little Tennessee River and the lower Tellico River. While TVA is careful to refer to its artificial lakes as reservoirs (such as "Tellico Reservoir"), common usage tends to refer to the reservoir as "Tellico Lake". The lake is approximately 16,000 acres in surface area and provides 357 miles of shoreline.
Document 7: Lake Tshangalele: Lake Tshangalele, also known as Lake Lufira or Mwadingusha Reservoir, is an artificial lake in the south-east of the Democratic Republic of Congo. It is located about 20 km east of the city of Likasi in the old province of Katanga. It lies at about 1,100 m above sea-level in a large depression surrounded by low mountains. It was created by a dam built on the Lufira River near Mwadingusha in 1926 to provide hydro-electric power. The area of open water is about 362.5 km. During the wettest months of February and March, the area flooded reaches a maximum of 440 km. The lake is shallow with a mean depth of only 2.6 m.
Document 8: Republic of the Congo: Before the 1997 war, about 9,000 Europeans and other non-Africans lived in Congo, most of whom were French; only a fraction of this number remains. Around 300 American expatriates reside in the Congo.
Document 9: Turtle-Flambeau Flowage: The Turtle-Flambeau Flowage was created in 1926 when the "Chippewa and Flambeau Improvement Company" built a dam on the Flambeau River downstream from its confluence with the Turtle River. The dam flooded 16 natural lakes and formed an impoundment of approximately 14,000 acres.
Document 10: Republic of the Congo: The region was dominated by Bantu-speaking tribes at least 3,000 years ago, who built trade links leading into the Congo River basin. Congo was formerly part of the French colony of Equatorial Africa. The Republic of the Congo was established on the 28th of November 1958 but gained independence from France in 1960. The sovereign state has had multi-party elections since 1992, although a democratically elected government was ousted in the 1997 Republic of the Congo Civil War, and President Denis Sassou Nguesso, who first came to power in 1979, has ruled for 35 of the past 40 years.

Large numbers of missionaries left the country when fighting broke out between rebel and government forces in 2002–3, but many of them have now returned to continue their work.
Document 12: Republic of the Congo: Ethnically and linguistically the population of the Republic of the Congo is diverse—Ethnologue recognises 62 spoken languages in the country—but can be grouped into three categories. The Kongo are the largest ethnic group and form roughly half of the population. The most significant subgroups of the Kongo are Laari in Brazzaville and Pool regions and Vili around Pointe-Noire and along the Atlantic coast. The second largest group are the Teke who live to the north of Brazzaville with 17% of the population. Boulangui (M’Boshi) live in the northwest and in Brazzaville and form 12% of the population. Pygmies make up 2% of Congo's population.
Document 13: Batang Ai Dam: The Batang Ai Dam is a concrete-face rock-fill dam in Batang Ai National Park in Sarawak, Malaysia. The power station comprises four turbines, totalling the installed capacity to . The station is operated by Sarawak Electricity Supply Corporation. Preparations for the dam began as early as 1975, before the design was published in 1977. Construction started 1982 with the river diversion work and the last turbine completed in 1985. The Batang Ai project, a relatively modest dam financed by the Asian Development Bank, caused the displacement of approximately 3,000 people from 26 longhouses. (These people have since been accommodated in the Batang Ai Resettlement Scheme to cultivate cocoa and rubber but the programme has not been successful.
Document 14: Akosombo Dam: The Akosombo Dam, also known as the Volta Dam, is a hydroelectric dam on the Volta River in southeastern Ghana in the Akosombo gorge and part of the Volta River Authority. The construction of the dam flooded part of the Volta River Basin, and led to the subsequent creation of Lake Volta. The flooding that created the Lake Volta reservoir displaced many people and had a significant impact on the local environment. Lake Volta is the largest man-made lake in the world by surface area. It covers , which is 3.6% of Ghana's land area. With a volume of 148 cubic kilometers, Lake Volta is the world's third largest man-made lake by volume, the largest being Lake Kariba which is located between Zimbabwe and Zambia in Southern Africa and contains 185 cubic kilometers of water.
Document 15: Republic of the Congo: The Republic of the Congo's sparse population is concentrated in the southwestern portion of the country, leaving the vast areas of tropical jungle in the north virtually uninhabited. Thus, Congo is one of the most urbanized countries in Africa, with 70% of its total population living in a few urban areas, namely in Brazzaville, Pointe-Noire or one of the small cities or villages lining the 534-kilometre (332 mi) railway which connects the two cities. In rural areas, industrial and commercial activity has declined rapidly in recent years, leaving rural economies dependent on the government for support and subsistence.
