India hosts significant mangrove forests, with the Sundarbans being the largest. However, these ecosystems face threats from cyclones, rising sea levels, deforestation, pollution, and rapid urbanisation, leading to habitat degradation and loss.<\/span><\/p>\r\n<p><span style=\"font-weight: 400\">To protect <strong>mangroves<\/strong>, global initiatives like the Ramsar Convention and national programs such as MISHTI and CRZ regulations have been implemented.
