Wetland Ecosystems and Forest Cover in India
- Statement 1: Paddy Cultivation and Wetlands
- Approximately 70% of India's wetland areas are utilized for paddy cultivation. This highlights the significant role of wetlands in agriculture, particularly for rice production.
- Wetlands, in general, are crucial for biodiversity, water purification, and flood control. Their conversion for agricultural purposes, while important for food security, can impact these ecological functions.
- Statement 2: Ramsar Convention and Protected Wetlands
- Chilika Lake in Odisha and Keoladeo National Park in Rajasthan are indeed recognized and protected under the Ramsar Convention.
- The Ramsar Convention is an international treaty signed on 2 February 1971 by UNESCO. It aims to promote the conservation and wise use of wetlands.
- Chilika Lake is the largest coastal lagoon in India and the second largest in the world, known for its rich biodiversity and migratory birds.
- Keoladeo National Park (formerly Bharatpur Bird Sanctuary) is a UNESCO World Heritage Site and a significant bird habitat.
- Statement 3: Mangrove Forest Coverage
- This statement is incorrect. Mangrove forests in India constitute a much smaller percentage of the world's total mangrove cover.
- India has about 4,992 square kilometers of mangrove cover, which is approximately 3% of the world's total mangrove area.
- The Sundarbans, shared between India and Bangladesh, is the largest mangrove forest in the world.
- Mangrove ecosystems are vital coastal barriers, nurseries for marine life, and effective carbon sinks.
Key Indian Wetland and Forest Facts for Exams
- Wetland (Ramsar) Sites in India: India has numerous Ramsar sites, and candidates should be aware of prominent ones like Vembanad Kol Wetland (Kerala), Ashtamudi Wetland (Kerala), Sasthamcotta Lake (Kerala), Wular Lake (Jammu & Kashmir), and Sambhar Lake (Rajasthan).
- Mangrove Forests in India: The distribution of mangroves is primarily along the east and west coasts, with West Bengal (Sundarbans) having the largest area, followed by Gujarat and the Andaman & Nicobar Islands.
- Importance of Forest Types: Understanding different forest types in India, including littoral and swamp forests, their geographical distribution, and ecological significance is essential for competitive exams.
