Lake Kivu
Unknown to Europeans, despite their presence in Africa, until 1894 when it was visited by the German Count Adolf von Gotzen, Lake Kivu is nestled between the Democratic Republic of Congo and Rwanda, and a hidden gem in the heart of Africa. This stunning freshwater lake, which covers an area of 2,700 square kilometres, offers a unique combination of natural beauty, ecological significance, and potential for economic development. Lake Kivu is 55.3 miles long and just under 30 miles wide, with water from the lake flowing into the Ruzizi River, which, in turn, flows southwards into Lake Tanganyika. Lake Kivu has three towns on its shore Gisenyi, Rubona and Kibuye and has a number of islands within its waters one of which, Idjwi, is the world's tenth largest inland island. | |
Lake Kivu is one of the African Great Lakes, a group of lakes formed as a result of tectonic activity along the East African Rift. The lake is situated at an elevation of 1,460 meters above sea level and has a maximum depth of 480 meters, making it one of the deepest lakes in the world. The lake's unique geology is due to its position atop a rift valley, which causes it to be under considerable pressure. This pressure, combined with the presence of methane gas and other dissolved gases, has led to concerns about the potential for a limnic eruption. However, recent studies have shown that the risk of such an event is low, and the lake's natural beauty remains a major draw for tourists and researchers alike.
Lake Kivu is home to a diverse array of plant and animal life. The lake's waters support a variety of fish species, including the endemic Lake Kivu sardine (Limnothrissa miodon), which is a key component of the local fishing industry supporting the livelihoods of the 6,563 fishermen who work the Lake, although this number has declined since the Rwandan genocide as many of these fishermen and their family's were killed during that conflict. (Indeed, Lake Kivu became notorious during that period as many of those slaughtered had their bodies dumped in the lake.) In addition, the lake's shores provide habitat for numerous bird species, including the African fish eagle and the pied kingfisher.
The lake's ecological significance extends beyond its borders, as it is part of the Albertine Rift montane forests ecoregion, which is recognised as a biodiversity hotspot due to its high levels of endemism. The ecoregion is home to several threatened species, including the mountain gorilla and the Virunga volcanoes. Lake Kivu holds great potential for economic development in the region as one of the most promising aspects of Lake Kivu is its vast reserves of methane gas, which are estimated to be over 55 billion cubic meters. The extraction of methane gas from the lake could provide a clean, renewable source of energy for the region, reducing dependence on fossil fuels and promoting sustainable development.
Several projects are currently underway to harness the methane gas from Lake Kivu. The KivuWatt project, for example, has already begun extracting methane gas from the lake and converting it into electricity, which is then sold to the Rwandan national grid.
