- The eastern states like Bihar and West Bengal are known for growing rice and jute, thanks to the fertile soil deposited by the Ganges and Brahmaputra rivers.
- Coastal regions like Kerala and Karnataka support the cultivation of coconut, rubber, and spices, benefiting from both tropical rains and rich soil.
- Rajasthan, being largely arid, relies on irrigated agriculture and grows wheat, barley, millets, and cotton in areas with adequate water supply.
- Rainfed agriculture is prominent in areas like Madhya Pradesh and parts of Uttar Pradesh, where soybean, maize, and pulses are grown.
- Hilly regions like Himachal Pradesh and Jammu & Kashmir focus on apple cultivation, while also supporting wheat, maize, and vegetables.
53. What is the role of rivers in India’s economy?
- Answer:
- Rivers in India serve as vital sources of irrigation, supporting the cultivation of crops in the fertile river basins, such as the Ganges, Yamuna, Godavari, and Krishna.
- Major rivers like the Ganges and Indus support large populations and contribute significantly to the agricultural economy, supplying water to millions of farmers.
- Rivers provide essential drinking water to cities, towns, and villages across India, with cities like Kolkata, Varanasi, and Allahabad located on riverbanks.
- River valleys are often rich in minerals, making these regions important for mining industries, especially in the Ganga-Yamuna Doab and Chhattisgarh.
- The transportation of goods via riverways is crucial, with rivers like the Ganges and Brahmaputra supporting cargo transport for agricultural produce, minerals, and raw materials.
- Rivers contribute to the hydroelectric power sector, with dams on rivers like the Bhakra Nangal Dam on the Satluj River and the Sardar Sarovar Dam on the Narmada providing electricity to large parts of India.
- Rivers also support fishing industries, with abundant fish resources in the Ganges, Godavari, and Kaveri rivers, forming an integral part of local economies.
- In addition to their economic value, rivers are central to India’s cultural heritage, being worshiped as sacred and forming an important part of the country’s traditions.
- Flooding of rivers during the monsoon can be both a boon (for agriculture) and a curse (leading to destruction of infrastructure and displacement of people).
- Sustainable river management is key to balancing economic use with environmental protection to ensure the long-term health of these water resources.
54. What are the challenges faced by India in managing its natural resources?
- Answer:
- Deforestation is a major challenge as urbanization, agriculture, and logging activities deplete India’s forests, affecting biodiversity and contributing to soil erosion.
- The over-exploitation of water resources, especially in agriculture, has led to the depletion of groundwater in regions like Punjab and Rajasthan.
- Pollution from industries, agriculture, and urban areas severely impacts air quality, water resources, and soil health, especially in cities like Delhi and Mumbai.
- The degradation of wetlands due to land reclamation and urban expansion threatens critical ecosystems and biodiversity, particularly in areas like the Sundarbans.
- Soil erosion in the Himalayas, Deccan Plateau, and coastal regions is exacerbated by human activities, leading to a loss of arable land and fertile soil.
- Overfishing in coastal areas and depletion of marine resources threaten the livelihoods of fishermen and the health of marine ecosystems.
- Climate change is affecting monsoon patterns, leading to unpredictable rainfall, increased droughts, and flooding, putting stress on India’s water resources.
- Land degradation in arid and semi-arid regions, such as parts of Rajasthan and Madhya Pradesh, reduces agricultural productivity and exacerbates desertification.
- The loss of biodiversity due to habitat destruction, poaching, and pollution threatens India’s rich wildlife and ecosystem services.
- Sustainable development policies, focusing on resource conservation, renewable energy, and eco-friendly practices, are crucial to mitigate the challenges India faces in managing its natural resources.
55. How does India’s topography influence its natural vegetation?
- Answer:
- India’s topography significantly influences the distribution of its natural vegetation by determining the climatic conditions, soil types, and altitude in various regions.
- Tropical forests are prevalent in the western coast, northeastern states, and parts of central India due to the high temperatures and high rainfall.
- The Himalayan region supports temperate forests at higher elevations, with coniferous trees such as pine and deodar growing at altitudes above 1,500 meters.
- The Thar Desert in the west supports xerophytic vegetation like cactus, acacia, and scrub, adapted to arid conditions and low rainfall.
- The Ganges-Brahmaputra delta supports mangrove vegetation in its coastal areas, with Sundarbans being home to the unique mangrove ecosystem. 6. Tropical dry forests and deciduous forests are found in parts of Madhya Pradesh, Maharashtra, and Chhattisgarh, where the climate is marked by seasonal rainfall. 7. Savannas and grasslands are found in regions with seasonal rainfall, like the Deccan Plateau and parts of Rajasthan, supporting tall grasses and shrubs. 8. The coastal plains support mangroves, salt-tolerant plants, and coconut trees along the western and eastern coasts due to the proximity to the sea. 9. Alpine vegetation is found at high altitudes in the Himalayas, characterized by alpine meadows, mosses, and lichens in the colder regions. 10. India’s topographical diversity contributes to a wide range of vegetation types, making it one of the world’s most biodiverse regions with varied ecosystems and habitats.
