Arakan Mountains

Arakan Mountains. This major mountain range forms a formidable natural barrier along the western coast of Myanmar, separating the Bay of Bengal from the country's central dry zone. Stretching approximately 950 kilometers from Naga Hills in the north to Cape Negrais in the south, the range is characterized by steep, rugged terrain and dense, biodiverse forests. Its highest peak is Mount Victoria, a significant landmark within Chin State.

Geography

The range arcs through several administrative divisions, primarily defining the geography of Rakhine State and forming the western border of Chin State. Major peaks include Mount Kennedy and Mount Victoria, the latter being a prominent feature within Chin State. The mountains create a sharp climatic divide, intercepting moisture from the Bay of Bengal during the Southwest monsoon, which results in extremely high rainfall on their western slopes. This orographic effect leaves the central Irrawaddy basin in a pronounced rain shadow. Key rivers such as the Kaladan River and the Lemro River have carved deep valleys through the range, flowing westward into the Bay of Bengal.

Geology

Geologically, the range is part of the complex Indo-Australian and Eurasian Plate collision zone, with formations related to the broader Himalayan orogeny. The structure consists primarily of folded and faulted sedimentary rocks, including sandstone, shale, and limestone, dating from the Mesozoic to Cenozoic eras. Significant tectonic activity is evidenced by the presence of the prominent Kaladan Fault and the Chittagong Coastal Plain. These geological processes have created a landscape vulnerable to landslides and seismic events, particularly during the intense monsoon seasons.

Ecology

The ecology is stratified by elevation, featuring tropical and subtropical moist broadleaf forests at lower levels and montane forests at higher altitudes. The range is part of the Indo-Burma biodiversity hotspot, hosting numerous endemic species. Notable fauna includes the endangered Arakan forest turtle, the Western hoolock gibbon, and the Asian elephant. The Mount Victoria area is particularly rich in endemic rhododendron species and rare orchids. Conservation challenges are significant due to deforestation, primarily for agriculture and timber extraction, threatening habitats for species like the sun bear and the clouded leopard.

History

Historically, the mountains served as a formidable barrier influencing the development of independent kingdoms like the Kingdom of Mrauk U, which maintained distinct cultural and political ties with Bengal and Southeast Asia. The range witnessed significant military campaigns, including operations during the Anglo-Burmese Wars and fierce jungle fighting in the Burma Campaign of World War II, such as the Battle of the Admin Box. For centuries, they marked a fluid frontier between Burmese, Bengali, and British spheres of influence, with Chin and Rakhine communities maintaining relative autonomy in the highlands.

Human activity

Human activity is predominantly characterized by shifting cultivation, practiced by the Chin, Mro, and Khami ethnic groups. The primary crops are hill rice and maize. In recent decades, the extraction of natural resources, including timber and gemstones, has increased, often involving external enterprises from Yangon and China. The region remains one of the least developed in Myanmar, with limited infrastructure; travel is often restricted and relies on arduous foot trails. Religious and cultural practices among the Chin, many of whom are Baptists, remain distinct from the predominantly Buddhist lowlands of Rakhine State.
