Pradesh ,one of the most sparsely populated states of India, covers an
area of 83743 sq. Kms. This region acquired an independent political
status in January 20, 1972, when it was declared as Union Territory
under the name of Arunachal Pradesh. The state of Arunachal Pradesh Bill
was passed by the Parliament in 1986 and with effect from February 20,
1987 Arunachal Pradesh became the 24th state of Indian Union.
It is a land
of lush green forests, deep river valleys and beautiful plateaus. The
land is mostly mountainous with the Himalayan range along the northern
borders criss-crossed with ranges running north-south. These divide the
state into five river valleys: the Kameng, the Subansiri, the Siang, the
Lohit and the Tirap. All these are fed by snow from the Himalayas and
countless rivers and rivulets.
