Overview:

Recently, a new scientific report published in the journal Nature shows that significant precipitation changes and increasing extreme climate events affecting the large human populations as well as endemic biodiversity of Lake Victoria Basin

Key findings of the report:

  • Heavy rains, wind storms, and floods threaten the survival and water access of the communities living in the Lake Victoria Basin (LVB), East Africa.
  • Nearly 40 million inhabitants are strongly affected by extreme weather events such as regular flooding.
  • The resultant massive flooding in lake-adjacent areas displaced over 200,000 people in Kenya, Uganda and Tanzania.
  • Lake Victoria and its surrounding wetlands and forests have faced extreme pressure and degradation due to rapid population growth, agricultural expansion, urbanisation and industrialisation.

About Lake Victoria:

  • It is the world’s second-largest freshwater lake.
  • Location: It is located in East Africa, bordered by Tanzania, Uganda, and Kenya.
  • It is also called Victoria Nyanza in Kenya, Nalubaale in Uganda, and Ukerewe in Tanzania.
