Unveiling the Marvels of Indian Wetlands: Distribution, Ecological Importance, Challenges, and Conservation

Abstract

Comparable to tropical evergreen forests or coral reefs, wetland ecosystems are among the most dynamic and productive ecosystems on the planet. A region's dynamism may have a substantial impact on its ecological sustainability. Exploring the distribution, range, categorization, ecological functions, biological variety, and dangers to India's wetland diversity is the goal of this article. The management of irrigation water, groundwater, fisheries, non-timber forest products, water supply, recreation, and pollution control through carbon sequestration, flood control, nutrient cycles are just a few of the essential ecological services that wetlands typically provide for sustainable development in many areas. However, the growing anthropogenic activity in and around the wetlands put them under ongoing stress, which is seen as a reduction in area and has a severe impact on their hydrological, ecological, and economic functions. Wetlands are one of the most imperilled ecosystems due to the global decline in their number. India has 75 wetlands that are currently recognised as Ramsar sites, with a total coverage of roughly 1.09 million hectares and an estimated 757.06 thousand wetlands, making up around 4.7% of the total land area. India has the most wetlands in South Asia, and it sustains nearly a fifth of the region's total biodiversity. Unfortunately, between 35–60% of India's wetlands have been lost over the course of the last 40 years, necessitating the creation of new conservation techniques and a rethinking of the laws governing their protection.
