Kutch district is a district of Gujarat state in western India. Covering an area of 45,652 km², it is the largest district of India.
Kutch literally means something which intermittently becomes wet and dry; a large part of this district is known as Rann of Kutch which is shallow wetland which submerges in water during the rainy season and becomes dry during other seasons. The same word is also used in the languages of Sanskrit origin for a tortoise. The Rann is famous for its marshy salt flats which become snow white after the shallow water dries up each season before the monsoon rains.
The district is also famous for ecologically important Banni grasslands with their seasonal marshy wetlands which form the outer belt of the Rann of Kutch.
Kutch District is surrounded by the Gulf of Kutch and the Arabian Sea in south and west, while northern and eastern parts are surrounded by the Great and Little Rann (seasonal wetlands) of Kutch. When there were not many dams built on its rivers, the Rann of Kutch remained wetlands for a large part of the year. Even today, the region remains wet for a significant part of year. The district had a population of 1,583,500 of which 30% were urban as of 2001.Motor vehicles registered in Kutch district have their registration Number starting with GJ-12.
