Mizoram

Relief and drainage

Geologically, the Mizo Hills form a part of the Rakhine (Arakan) Mountains, a series of compact parallel ridges with a north-south axis formed of sandstone, limestone, and shales—all Cenozoic rocks between 2.6 and 65 million years old. The ridges, separated by narrow river valleys, rise to about 7,000 feet (2,100 metres). In the south, the Kaladan River and its tributaries flow southward into Myanmar, while the Dhaleswari (Tlawng) and Sonai (Tuirail) rivers flow north into Assam.

Climate

The climate in Mizoram is moderate. During the coolest months (November through February), temperatures in Aizawl typically rise from the low 50s (low 10s C) into the high 60s F (about 20 °C) daily. In the warmest months (June through August), minimum temperatures are in the high 60s F, while maximum temperatures usually peak in the mid-80s F (about 30 °C). Rainfall averages about 100 inches (2,500 mm) annually, with most brought by the southwest monsoon (which blows from May to September).

Plant and animal life

More than three-fourths of the land area of Mizoram is forested. Thick evergreen forests contain valuable timber trees, such as champak (Michelia champaca), ironwood, and gurjun (genus Dipterocarpus). The woodlands also provide habitat for many animals, including elephants, tigers, bears, deer, monkeys, gibbons, and serows (wild goatlike mammals). Such animals are protected in a number of national parks and wildlife sanctuaries.

Population composition

The residents of Mizoram consist almost entirely of Scheduled Tribes (an official category embracing indigenous groups that fall outside the predominant Indian social hierarchy). These groups are loosely called Mizo, a local term meaning “highlanders.” Among the most prominent of the Mizo peoples are the Kuki, Pawi, and Lakher. Most of the Mizo are Tibeto-Burman peoples, speaking Mizo or a closely related Tibeto-Burman language or dialect. One group in the state, however, the Chakma, speaks an Indo-Aryan language. Mizo and English are the principal and official languages. Having no script of its own, Mizo uses the Roman alphabet.

Christian missionaries began to work in the Mizo Hills area in the late 19th century. Consequently, the great majority of the population is Christian—predominantly Protestant—with most conversions having occurred in the 1920s and ’30s. Buddhists form the largest religious minority in Mizoram, followed by Hindus and Muslims; there also are tiny groups of Sikhs and Jains.

Settlement patterns

Mizoram is one of the most sparsely populated states of India. The population density decreases from north to south, owing primarily to a southward increase in humidity and temperature that renders the area less desirable for habitation. Aizawl is the state’s only major city; large towns include Lunglei, in the eastern part of the state, and Champhai, in the south-central region.

Agriculture

Agriculture is the dominant economic activity of Mizoram, engaging more than two-thirds of the workforce in the early 21st century. Two types of agriculture are practiced: terrace cultivation, in which crops are planted on relatively permanent, graduated terraces on the sides of hills and mountains to conserve water and reduce soil loss; and shifting agriculture, in which tracts—called jhum—are cleared by burning, cultivated for a limited period of time, and then abandoned for a number of years to allow regeneration of the natural vegetation and nutrients in the soil. An increase in the number of people farming in the 20th century forced a reduction in the traditional eight-year cycle of jhum regeneration, which in turn resulted in a decrease in farm productivity. Rice, corn (maize), cotton, and vegetables are the main crops.

Manufacturing

The government of Mizoram has assisted and encouraged an array of small-scale industries at the village level. Such industries include sericulture (silk production), handloom and handicrafts workshops, sawmills and furniture manufacturing, oil refining, grain milling, and ginger processing. Major manufacturing activities, however, have not been strongly established.

Transportation

The infrastructure of Mizoram remains limited. However, the state is traversed by two national highways, and major roads serve most of the larger towns. Regular bus routes operate across the state, and some also provide interstate service. A small airport offers flights from Aizawl to neighbouring states. There are no railways in Mizoram.
