Geography
Context: A report by Refugees International, a humanitarian organisation has highlighted the dangerous link between climate change and conflict in countries like Cameroon, Chad, Niger and Nigeria in the Lake Chad Basin.
- Shrinking natural resources due to adverse weather are heightening tensions across communities and displacing people.
- Around 3 million people have been displaced and an additional 11 million need humanitarian assistance.
About Lake Chad:
- The Lake Chad is a vast area of fresh water located in the middle of sand dunes which covers territories in 4 countries: Nigeria, Cameroon, Niger and Chad.
- Palaeography informs us that the Lake Chad has been constantly evolving with respect to the environmental conditions.
- It is an endorheic lake fed mainly by the Logone Chari and Komadougou watercourses.
- This ecosystem contains a great variety of wet zones which include open water, polders, temporary or permanent ponds, some of them being rich in natron.
- Around the lake, sand deserts and water meet in a complex network of meanders which are sometimes cultivated.
- Receding waters in dry season expose wide floodplains on the banks of the lake.
- They shelter water plants such as papyrus and spirulina but also numerous animal species such as the migratory birds, which use these plains as resting areas.
- The Chad Basin National Park (Lake Chad Nigeria Section) is located between Borno and Yobe states in the extreme north-eastern corner of Nigeria.
- The Park is generally described as being in the conventional basin of the famous but rapidly shrinking Lake Chad.
- The Chad Basin remains the only existing stronghold of Giraffe and Ostrich in Nigeria.
- The Lake Chad environment presents an exceptional mosaic of plant formations forming as many biotopes, oasis and wet zones of international importance.
- The Lake Chad and its islands, maintain their natural morphology which gorges this cultural landscape on which human communities developed.
- The Chad Basin National Park shares the same ecosystem with the Waza National Park in the Republic of Cameroon to the east.
- Its Wetlands and Oases are very important in the mitigation of the desertification process in north-eastern Nigeria and the overall conservation management efforts of the Chad Basin as a whole.
- The natural values are almost identical to those of the Okavango Delta, the Lakes of Ounianga and the Kenya Lake System in the Great Rift Valley in Africa; but they are also comparable to those of the West Lake Cultural Landscape of Hangzhou in China and the Ahwar of Southern Iraq.
