Context:
- Floods in Rwanda
- At least 130 people have died after floods and landslides hit Rwanda’s northern and western provinces.
- The Western Province bordering Lake Kivu and the district Rubavu are some of the badly affected regions.
- Rwanda’s weather authority is linking the unusual rains seen in recent years to climate change.
- Many factors contribute to flooding, but a warming atmosphere caused by climate change makes extreme rainfall more likely.
African Great Lakes:
- The Great Lakes of Africa refer to a series of large, interconnected lakes in East and Central Africa, including Lake Victoria, Lake Tanganyika, Lake Malawi, Lake Albert, Lake Edward, and Lake Kivu.
- These lakes are some of the deepest and largest freshwater lakes in the world, with a combined surface area of over 143,000 square kilometres and a total volume of about 18,000 cubic kilometres. They hold approximately 27% of the world’s freshwater.
- The lakes are an important source of water, food, and livelihoods for millions of people in the region, supporting fishing, agriculture, and other economic activities.
- The lakes also play a crucial role in the region’s ecology, supporting a rich array of aquatic plant and animal species, including several endangered species such as the Nile crocodile and the hippopotamus.
- Lake Victoria is the largest of the Great Lakes of Africa, with a surface area of over 68,800 square kilometres. It is set between the Rift Valleys and is bounded by uplifted mountains and highlands associated with rifting.
- Compared to the other lakes, it is geologically younger (less than half a million years) and much shallower with markedly lower water clarity.
- It is shared by three countries: Tanzania, Uganda, and Kenya.
- Lake Tanganyika is the second-deepest lake in the world and the longest freshwater lake in the world. It is shared by four countries: Tanzania, the Democratic Republic of Congo, Zambia, and Burundi.
- Lake Malawi is the third-largest of the Great Lakes of Africa. It is shared by Malawi, Tanzania, and Mozambique.
- Lake Albert is located on the border between Uganda and the Democratic Republic of Congo, and is named after Prince Albert of Belgium. It is relatively shallow and has a maximum depth of about 50 metres.
- Lake Edward is located on the border between Uganda and the Democratic Republic of Congo, and is named after Prince Edward of the United Kingdom.
- Lake Kivu is located on the border between the Democratic Republic of Congo and Rwanda, and is one of only three known lakes in the world that contains a large amount of dissolved gas, primarily methane and carbon dioxide.
