The term "rann" refers to a type of salt marsh or wetland, often characterized by its unique ecosystem. These areas are typically found in regions with high evaporation rates, leading to the accumulation of salt. The most famous example is the Rann of Kutch in India, which is known for its vast, arid landscape and seasonal flooding. Ranns are important for biodiversity, providing habitat for various species of birds, fish, and other wildlife. They also play a crucial role in local economies, supporting activities like fishing and tourism. Additionally, these wetlands help in maintaining ecological balance by filtering water and preventing soil erosion.
