The International Day for the Conservation of the Mangrove Ecosystem, celebrated annually on July 26th, promotes awareness concerning the importance and vulnerability of mangrove ecosystems. Adopted by the UN Educational, Scientific and Cultural Organization in 2015, the day encourages sustainable management, conservation, and utilization of these unique ecosystems.
Status and Characteristics of Mangroves in India
Mangroves are coastal ecosystems found in tropical and subtropical regions and characterized by their ability to resist harsh conditions such as saline water and tidal fluctuations. Unique features include the ability to germinate seeds within the tree to overcome the challenge of saline water and adapt root systems to impede water flow, providing support against tides.
According to the Indian State Forest Report 2021, India’s mangrove cover extends to 4992 sq. Km, comprising 0.15% of the country’s total geographical area. The Sundarbans in West Bengal is the largest mangrove forest region globally, followed by substantial areas in the Andamans, Kachchh, and Jamnagar in Gujarat.
Significance of Mangroves
Biodiversity conservation is a key role of mangroves; they serve as unique habitats for various plant and animal species, contributing to breeding, nursery, and feeding grounds. Notably, the Sundarbans host the Royal Bengal Tiger and the Irrawady Dolphin, among other species.
Mangroves act as natural buffers against coastal erosion, storm surges, and tsunamis, reducing the impact of waves and currents. They can also absorb significant amounts of energy during hurricanes and cyclones, protecting inland regions and human settlements.
Mangroves also function as efficient carbon sinks, sequestering large amounts of carbon dioxide from the atmosphere in their biomass and sediments. They enhance local food security, improve water quality, and provide recreational opportunities, which can boost the economy of local communities.
Challenges Faced by Mangroves
Mangroves are often subjected to habitat destruction and fragmentation, resulting from activities such as agriculture, urbanization, aquaculture, and infrastructure development. Furthermore, climate change and rising sea levels pose significant threats. Pollution from agricultural runoff, industrial discharges, and improper waste disposal also contaminates these habitats.
The lack of integrated management techniques is another challenge. Effective conservation requires considering mangroves’ interconnectedness with adjacent ecosystems such as coral reefs and seagrass beds.
Government Initiatives for Mangrove Conservation
Government initiatives such as MISHTI (Mangrove Initiative for Shoreline Habitats & Tangible Incomes), and the Sustainable Aquaculture In Mangrove Ecosystem (SAIME) initiative are steps towards addressing mangrove conservation.
Way Forward for Conservation and Management of Mangroves
Drone monitoring and AI could be adopted for efficient surveillance over vast areas and timely detection of illegal activities. A Mangrove Adoption Program where individuals or corporations can “adopt” a patch of mangroves can foster responsibility for maintenance and restoration.
Investment in mangrove research and development can explore novel applications such as phytoremediation to clean polluted water or new medicines from mangrove plant extracts. These innovations can leverage mangroves’ unique properties for sustainable development.
UPSC Civil Services Examination – Previous Year Questions
One of the questions for the preliminary examination in 2015 inquired about which region in India comprised mangrove forest, evergreen forest, and deciduous forest. The answer was (d) Andaman and Nicobar Islands.
A question for the mains examination in 2019 asked for a discussion on the causes of mangrove depletion and an explanation of their importance in maintaining coastal ecology.
