It promotes best management practices and seeks to make local communities stakeholders in conservation and income generation.<\/li>\n<li><strong>National Coastal Mission Programme<\/strong>: Through its \u2018Conservation and Management of Mangroves and Coral Reefs\u2019 initiative, the government provides guidance and financial assistance to states for preparing and implementing Management Action Plans (MAPs) focusing on survey, demarcation, afforestation, and awareness.<\/li>\n<li><strong>Coastal Regulation Zone (CRZ) Notification (2019)<\/strong>: Under the Environment (Protection) Act, 1986, this regulation strictly regulates development activities in mangrove-adjacent coastal zones.<\/li>\n<li><strong>Co-Management Committees<\/strong>: In states like Maharashtra, co-management approaches involving local communities, gram panchayats, and women&#8217;s self-help groups have successfully restored mangroves while improving climate resilience and livelihoods.<\/li>\n<li><strong>NGO and Public Engagement<\/strong>: Projects led by organizations like WWF India and the Aga Khan Rural Support Programme actively involve locals in restoration and stewardship, promoting education and sustainable aquaculture within mangrove ecosystems.<\/li>\n<li><strong>Mangrove Alliance for Climate:<\/strong> India became a member of the Mangrove Alliance for Climate (MAC) in 2022, enhancing international knowledge-sharing and scaling up best conservation practices.<\/li>\n<\/ol>\n<h2><span style=\"text-decoration: underline;\"><strong><a id=\"h5\"><\/a>What can be the way forward?<\/strong><\/span><\/h2>\n<ol>\n<li><strong>Enhance and enforce national and state-level policies:<\/strong> Update and rigorously enforce laws (like India\u2019s CRZ Notification, Forest Acts, and EIA norms) to prohibit destructive activities, enable restoration, and define clear frameworks for ownership and access rights.<\/li>\n<li><strong>Integrate mangroves into climate and disaster adaptation plans:<\/strong> Recognize mangroves as &#8220;natural coastal infrastructure&#8221; and prioritize their protection in all national and local planning.<\/li>\n<li><strong>Empower local communities, women\u2019s groups, and indigenous peoples:<\/strong> Communities that posses deep knowledge of mangrove ecosystems &amp; rely on them for their livelihoods &#8211; engage them in co-management, benefit-sharing, stewardship, and policy decisions.
