Cyclone Dana recently hit near Bhitarkanika National Park and Dhamra Port in Odisha, and luckily, the area didn’t suffer as much damage as many feared. This lesser impact was largely thanks to the natural protection offered by mangroves along the coast. These unique, resilient trees play a crucial role in safeguarding coastal regions from environmental threats, including cyclones, which are becoming more frequent due to climate change.Mangroves are extraordinary trees and shrubs that thrive in the challenging environment where rivers meet the sea. They are adapted to live in salty, tidal waters, making them different from most other plant species. Mangroves have special features like aerial roots that stick out of the water to help them breathe, and waxy, water-retaining leaves that cope with the salty conditions. These trees are so well adapted that they even start growing their next generation (known as propagules) while still attached to the parent tree, eventually dropping them into the water where they can root and grow independently.One of the world’s largest mangrove forests is the Sundarbans, stretching across India and Bangladesh. This vast region not only supports a diverse range of wildlife, including the iconic Bengal tiger, but also provides significant protection for coastal communities against the ravages of nature. How mangroves protect the coastMangroves stabilise coastal lands through their dense network of roots, which bind the soil and prevent erosion. This is crucial in maintaining the coastline and creating new landforms, especially as sea levels rise. The roots also help build up sediments in the water, which contributes to the growth of the mangrove forest and the expansion of coastal areas.Mangroves serve as natural barriers against severe weather. Their roots reduce the energy of incoming waves during storms and lower the height of storm surges, significantly decreasing potential damage to nearby communities. This buffering capacity is essential in lessening the impacts of cyclones and other intense weather events on human settlements and infrastructure. Adapting to tidal changesMangroves are masters of resilience, thriving in areas regularly flooded by tides. This daily inundation with seawater isn't a challenge for them but an advantage, allowing them to manage salt levels and remain healthy in habitats that would be hostile to other plants. Purifying waterBeyond stabilising coastlines and protecting against storms, mangroves play a crucial role in water purification. They absorb pollutants and excess nutrients from runoff, improving water quality and preventing harmful algal blooms that can kill marine life. Clear, clean water is vital for the health of coral reefs and seagrass beds, crucial components of marine biodiversity. Carbon storageMangroves are also champion carbon storers, sequestering atmospheric carbon in their dense wood and rich soil, a process vital for combating climate change. Despite covering less than 2% of marine environments, mangroves account for a significant portion of the carbon stored in coastal habitats, often referred to as "blue carbon." Supporting biodiversityThese forests are not just physical barriers or carbon sinks; they are vibrant ecosystems that provide habitat and breeding grounds for a wide array of species, from fish to birds to mammals. This biodiversity is essential for the ecological health of the region and supports local economies, particularly through fishing and tourism. Government initiativesRecognising the importance of mangroves, the Indian government has implemented several initiatives to promote their conservation. The India State of Forest Report (ISFR) 2023 shows an increase in mangrove cover in the country, reflecting the success of these efforts. Initiatives such as the Mangrove Initiative for Shoreline Habitats & Tangible Incomes (MISHTI) focus on enhancing mangrove forests while providing economic benefits to local communities, ensuring their active participation in conservation efforts.Additionally, the Sustainable Aquaculture in Mangrove Ecosystem (SAIME) promotes environmentally friendly aquaculture practices that align with mangrove health, demonstrating sustainable use of these natural resources. Public awareness campaigns and the Magical Mangroves initiative by WWF India play a critical role in educating people about the benefits of mangroves, further solidifying community support for mangrove preservation.Mangroves are indispensable to coastal ecosystems, offering a plethora of ecological, economic, and social benefits. They mitigate the effects of cyclones, stabilise coastlines, purify water, store carbon, and support rich biodiversity. As climate change continues to pose a growing threat to global ecosystems, the protection and restoration of mangroves become ever more crucial. The government's ongoing conservation efforts, coupled with community involvement and sustainable practices, are essential for maintaining these vital natural resources. By protecting mangroves, we safeguard our coasts and ensure a resilient environment for future generations.Natural defendersMangroves protect coastal areas from erosion by stabilising the shoreline with their intricate root systems. These roots can also diminish the impact of waves and reduce storm surge levels during hurricanes and cyclones.Biodiversity hotspotsMangrove forests are among the most productive and biologically complex ecosystems on Earth. They serve as nurseries for many marine species, including fish, crabs, shrimp, and molluscs, which find shelter in the roots.Carbon warriorsMangroves are incredibly efficient at storing carbon, much more so than most other types of forests. This characteristic makes them vital in the fight against climate change. The carbon they store in their waterlogged soils is often referred to as "blue carbon" because of its storage in coastal and marine habitats.Salt filtersMangroves have a unique ability to thrive in salty environments. They can filter out salt using special glands in their leaves, or they prevent salt from entering their system altogether through their roots. This adaptation allows them to live in conditions most trees cannot tolerate.Agricultural helpersThe leaf litter from mangroves contributes to nutrient-rich sediments that benefit agricultural fields. This litter decomposes and releases nutrients back into the environment, which helps support coastal agriculture.Medicinal potentialMangroves contain a variety of compounds with medicinal properties. Researchers have found substances in mangrove roots, bark, and leaves that can be used to treat ailments ranging from pain and inflammation to bacterial and fungal infections.Tidal warriorsMangroves are one of the few trees that can survive in changing tidal conditions. This ability allows them to cope with submersion twice a day in some areas. Their pneumatophores, or air roots, stick up out of the soil and help the tree breathe even when the roots are underwater.Survival expertsMangrove seeds are buoyant and can remain viable for over a year, floating on the water until they find suitable ground to root. This characteristic allows mangroves to spread and colonise areas far from their original location.Storm predictorsIn some regions, local communities observe the flowering patterns of mangroves to predict the coming of monsoon rains. Architectural inspirationsThe complex root systems of mangroves have inspired engineers and architects to design more effective water break structures and innovative building foundations, especially in flood-prone areas.
