FAQs on Wetlands - Geography Video Lecture - Geography for UPSC CSE
| 1. What are wetlands? |  |
Ans. Wetlands are areas of land that are saturated with water either permanently or seasonally. They are characterized by unique soil types and vegetation that are adapted to wet conditions.
| 2. Why are wetlands important? | |
Ans. Wetlands play a crucial role in the environment by providing various benefits. They act as natural filters, improving water quality by trapping pollutants and excess nutrients. Wetlands also serve as habitats for a wide range of plant and animal species, including migratory birds. Additionally, they help in flood control by absorbing and storing excess water during heavy rainfall.
| 3. What are the different types of wetlands? | |
Ans. There are several types of wetlands, including marshes, swamps, bogs, and fens. Marshes are characterized by grassy vegetation and are often found near rivers or lakes. Swamps, on the other hand, are dominated by trees and are usually located in forested areas. Bogs are acidic wetlands with nutrient-poor soils, while fens have alkaline or neutral pH levels and are rich in nutrients.
| 4. How are wetlands being threatened? | |
Ans. Wetlands are facing numerous threats, primarily due to human activities. These include drainage for agricultural purposes, urban development, pollution from industrial and agricultural runoff, and climate change. These factors can lead to the destruction and degradation of wetlands, resulting in the loss of their ecological functions and biodiversity.
| 5. What conservation measures are being taken to protect wetlands? | |
Ans. Various conservation measures are being implemented to protect wetlands. These include the establishment of protected areas and national parks to preserve wetland habitats. Additionally, international agreements such as the Ramsar Convention aim to promote the conservation and sustainable use of wetlands worldwide. Restoration projects are also being carried out to rehabilitate degraded wetlands and enhance their ecological functions.
