Explanations:Wetlands are areas where water covers the soil or is present either at or near the surface of the soil for varying periods of time during the year. They are crucial for biodiversity, water purification, flood control, and carbon storage. In India, the distribution of wetlands varies significantly among states due to differences in topography, climate, and human activities.
Assam, located in the northeastern part of India, has a high percentage of wetlands due to its unique geographical and climatic conditions. The state is characterized by a network of rivers, including the Brahmaputra, which forms extensive floodplains and wetlands. The humid climate and heavy rainfall contribute to the formation and maintenance of these wetlands. The wetlands in Assam are not only ecologically significant but also play a vital role in the state's agriculture and economy.
Other states like Uttar Pradesh, Andhra Pradesh, and Madhya Pradesh also have wetlands, but their percentage is lower compared to Assam. Uttar Pradesh, for example, has significant water bodies, but its diverse topography and extensive agricultural activities do not support a high percentage of wetlands. Similarly, Andhra Pradesh and Madhya Pradesh have wetlands, but their geographical and climatic conditions do not favor extensive wetland formation compared to Assam.
Understanding the geographical distribution of wetlands is important for environmental management, conservation efforts, and sustainable development. It is essential to recognize the unique characteristics of each state and how they influence the formation and maintenance of wetlands. This knowledge is crucial for students preparing for competitive examinations such as the UPSC, SSC, and State PSC, where questions on geographical features and environmental issues are common.
