Résumé
Nepal measures about along its Himalayan axis by across. It has an area of . Nepal is landlocked by China's Tibet Autonomous Region to the north and India on other three sides. West Bengal's narrow Siliguri Corridor separate Nepal and Bangladesh. To the east are Bhutan and India. Nepal has a very high degree of geographic diversity and can be divided into three main regions: Terai, Hilly, and Himal. The Terai region, covering 17% of Nepal's area, is a lowland region with some hill ranges and is culturally more similar to parts of India. The Hilly region, encompassing 68% of the country's area, consists of mountainous terrain without snow and is inhabited by various indigenous ethnic groups. The Himal region, covering 15% of Nepal's area, contains snow and is home to several high mountain ranges, including Mount Everest, the world's highest peak. Nepal, with elevations ranging from less than 100 meters to over 8,000 meters, has eight climate zones from tropical to perpetual snow. The majority of the country's population resides in the tropical and subtropical climate zones. The tropical zone, below 1,000 meters, experiences frost less than once per decade and is suitable for growing various fruits and crops. The subtropical climate zone, from 1,000 to 2,000 meters, is the most prevalent and suitable for growing rice, maize, millet, wheat, and other crops. The temperate climate zone, from 2,000 to 3,000 meters, occupies 12% of Nepal's land area and is suitable for cold-tolerant crops. The subalpine, alpine, and nival zones have progressively fewer human settlements and agricultural activities. Seasons are divided into a wet season from June to September and a dry season from October to June. The summer monsoon can cause flooding and landslides, while the winter monsoon is marked by occasional rainfall and snowfall. The diverse elevation results in various biomes, including tropical savannas, subtropical and temperate forests, montane grasslands, and shrublands.
