Short, clear answer:

• Strictly speaking, in Jambudvipa there is only one “Bharat Kshetra.” So total Bharat Kshetra = 1. Name: Bharata (also called Dakshin Bharata).

• If you meant “human-inhabited kshetras of Jambudvipa” (where Tirthankars appear across time), then they are 3:

1) Bharata Kshetra (south) 2) Mahavideha Kshetra (middle) 3) Airavata Kshetra (north)

Note: This layout is the same in both Digambar and Shvetambar traditions.
