Mizoram is a landlocked state in North East India whose southern part shares 722[8] kilometres long international borders with Myanmar and Bangladesh, and northern part share domestic borders with Manipur, Assam and Tripura. It is the fifth smallest state of India with 21,087 km2 (8,142 sq mi). It extends from 21°56'N to 24°31'N, and 92°16'E to 93°26'E.[33] The tropic of cancer runs through the state nearly at its middle. The maximum north–south distance is 285 km, while maximum east–west stretch is 115 km.[33]
Mizoram is a land of rolling hills, valleys, rivers and lakes. As many as 21 major hill ranges or peaks of different heights run through the length and breadth of the state, with plains scattered here and there. The average height of the hills to the west of the state are about 1,000 metres (3,300 ft). These gradually rise up to 1,300 metres (4,300 ft) to the east. Some areas, however, have higher ranges which go up to a height of over 2,000 metres (6,600 ft). Phawngpui Tlang also known as the Blue Mountain, situated in the southeastern part of the state, is the highest peak in Mizoram at 2,210 metres (7,250 ft).[34] About 76% of the state is covered by forests, 8% is fallows land, 3% is barren and considered uncultivable area, while cultivable and sown area constitutes the rest.[35] Slash-and-burn or jhum cultivation, though discouraged, remains in practice in Mizoram and affects its topography.[36][37] The State of Forest Report 2017 states that Mizoram has the highest forest cover as a percentage of its geographical area of any Indian state, being 86.27% forest.
