The state’s geography has influenced its agricultural practices, trade and commerce, and even its cultural and religious practices. In this context, understanding the geography of Bihar is essential to gaining an in-depth understanding of the state and its people.
Physical geography
Bihar is a state located in the eastern part of India, and it is the third-largest state in terms of population. The state is surrounded by Nepal to the north, West Bengal to the east, Uttar Pradesh to the west, and Jharkhand to the south. Bihar is known for its rich history, culture, and traditions, but it is also famous for its diverse physical geography.
The physical geography of Bihar is characterized by its location in the northern plains of India, with the Himalayas to the north and the Bay of Bengal to the east. The state covers an area of 94,163 km² and has a diverse landscape consisting of mountains, hills, plateaus, and plains. The state can be broadly divided into three physiographic regions, the Himalayan region, the Middle Ganga Plain, and the Chota Nagpur Plateau.
The Himalayan region of Bihar is located in the north and northeast parts of the state and includes the districts of Purnea, Kishanganj, and Katihar. This region is mainly characterized by the foothills of the Himalayas, which gradually merge into the Middle Ganga Plain. The elevation in this region varies between 150 and 610 meters, and the climate is mostly subtropical with high humidity and rainfall.
The Middle Ganga Plain is the largest physiographic region in Bihar, covering almost 80% of the state. This region is characterized by flat and fertile alluvial plains, which are formed by the Ganga and its tributaries. The soil in this region is highly productive, and it is suitable for agriculture. The plain is also dotted with numerous lakes, ponds, and wetlands, which support a rich variety of aquatic flora and fauna.
The Chota Nagpur Plateau is located in the southern part of Bihar and covers an area of about 16,000 km². This region is characterized by rolling hills, valleys, and plateaus, which are mostly covered with dense forests. The plateau is rich in mineral resources, including coal, iron, and mica, and it is an important mining region in India.
Apart from these three regions, Bihar is also home to several rivers, including the Ganga, Sone, Kosi, Gandak, and their tributaries. These rivers are an essential source of water for irrigation, drinking, and industrial purposes. The state also experiences a subtropical climate, with hot summers and cool winters.
In conclusion, the physical geography of Bihar is diverse and varied, consisting of mountains, hills, plateaus, and plains. The state’s landscape is characterized by three physiographic regions, the Himalayan region, the Middle Ganga Plain, and the Chota Nagpur Plateau, each with its unique features and resources. The state’s natural resources, including its fertile soil, mineral deposits, and water resources, have played a significant role in shaping its economy and development.
Climate
Climate is an important aspect of geography that significantly influences the natural resources, agriculture, and socio-economic development of a region. Bihar, located in the eastern region of India, experiences a diverse range of climatic conditions due to its location and topography. The state is known for its hot summers, cold winters, and extreme rainfall during monsoon season. This article aims to provide an in-depth analysis of the climate of Bihar and its impact on the state’s economy, agriculture, and environment.
The Climate of Bihar: Bihar experiences three distinct seasons: summer, monsoon, and winter. The summer season extends from March to May, with temperatures reaching up to 45°C in some parts of the state. The monsoon season, which starts in June and continues till September, brings heavy rainfall, leading to flooding in many areas. The winter season lasts from December to February, with temperatures dropping as low as 5°C in the northern regions of the state.
The average annual rainfall in Bihar is around 1,200 mm, with the highest rainfall recorded in the northeastern region. The state is also prone to droughts, with frequent occurrences in recent years due to erratic monsoons and decreasing groundwater levels.
Impact on Agriculture: Bihar’s economy is predominantly agricultural, and the state’s climate significantly impacts its agriculture sector. The monsoon season is crucial for the cultivation of crops, and the state’s agricultural output is heavily dependent on the timely arrival and distribution of rainfall. Erratic rainfall and flooding have severely affected crop yields, leading to losses for farmers. The state government has implemented various measures to combat the effects of climate change on agriculture, including crop diversification and the promotion of alternative livelihoods.
Impact on Environment: The climate of Bihar has also had a significant impact on the state’s environment. The state is prone to floods, landslides, and erosion, leading to damage to infrastructure and loss of life. The state government has undertaken various initiatives to mitigate the impact of climate change, including afforestation drives and the construction of embankments along rivers.
In conclusion, Bihar’s climate is diverse and challenging, with extreme temperatures, heavy rainfall, and frequent occurrences of natural disasters. The state’s economy and agriculture are heavily dependent on the timely arrival and distribution of rainfall, making it vulnerable to climate change. The state government has implemented various measures to combat the effects of climate change, but more needs to be done to ensure the sustainability of the state’s environment and economy in the long run.
Rivers and lakes
Bihar, located in eastern India, is known for its fertile plains and a rich network of rivers and lakes. The state is home to several important rivers, including the Ganges, the Kosi, and the Gandak. The rivers not only provide water for irrigation and agriculture but also serve as a vital means of transportation for the people of Bihar.
The Ganges, which is considered holy by Hindus, is the largest river in Bihar and plays a significant role in the state’s culture and economy. It originates in the Himalayas and flows through several states before entering Bihar near Buxar district. The river flows for about 505 km through Bihar, passing through important cities such as Patna, Bhagalpur, and Buxar, before exiting the state near Chhapra district. The river provides water for irrigation and supports a thriving fishing industry. The Ganges also serves as a source of drinking water for millions of people in Bihar.
The Kosi river, also known as the ‘Sorrow of Bihar’, is another important river that originates in Tibet and enters Bihar near Saharsa district. The river is notorious for its devastating floods that have caused massive damage to life and property in the past. The Bihar government has implemented several measures to control the floods, including the construction of embankments and reservoirs.
Apart from the rivers, Bihar is also home to several lakes, the most famous of which is the Barabar lake. The lake is situated in the Barabar hills in Jehanabad district and is known for its clear blue waters. The lake is a popular tourist destination and is surrounded by lush green forests.
The state also has several other small lakes and wetlands that provide a habitat for a variety of aquatic plants and animals. The Kanwar lake in Begusarai district, for example, is a major bird sanctuary and is home to several migratory birds during the winter months.
In conclusion, the rivers and lakes of Bihar play a crucial role in the state’s economy, culture, and environment. The Ganges, Kosi, and other rivers provide water for irrigation, transportation, and drinking, while lakes serve as tourist destinations and provide habitats for various flora and fauna. However, the state also faces challenges such as floods and water pollution that threaten the health and well-being of its people and ecosystems. It is, therefore, essential to adopt sustainable and responsible practices to ensure the preservation and conservation of Bihar’s natural resources.
