Mangroves are not merely environmental assets; they are powerful economic drivers and critical infrastructure for climate and economic resilience. 

• It is a stark reality that the immense value of these blue carbon ecosystems rarely features in financial balance sheets or national policy frameworks. 
• As the world grapples with extreme weather events and rising sea levels, the significance of mangroves becomes undeniable.

About Mangrooves

• Mangroves are salt-tolerant trees and shrubs found in coastal intertidal zones, where freshwater and seawater mix. 
• They grow in tropical and subtropical climates with high rainfall (1,000–3,000 mm) and temperatures between 26–35°C.
• Characteristics of Mangrove:
• • Vivipary: Seeds sprout while still on the parent tree, helping survival in salty, waterlogged conditions.
  • Aerial roots: These breathing roots (pneumatophores) absorb oxygen from the air.
  • Waxy and succulent leaves: Help reduce water loss and manage salt stress.
• Common Species: Red mangrove, Avicennia marina, grey mangrove, and Rhizophora are commonly found.

Importance of Mangroves

• Coastal Protection (Bio-shields): Their dense root systems reduce the force of storm surges and help prevent coastal erosion.
• Carbon Storage: Mangroves absorb carbon dioxide and store it in the soil for centuries, making them powerful carbon sinks.
  • Example: Carbon sequestration alone in the Sundarbans is valued at ₹462 million per year. This highlights their immense ecological and economic importance as natural carbon sinks, helping achieve carbon capture targets.
• Livelihood Source: Mangroves unlock significant opportunities for alternative livelihoods such as aquaculture, beekeeping, and eco-tourism.
• Biodiversity Hotspots: Serve as breeding and nursery grounds for fish, birds, and reptiles. Their rich biodiversity supports complex food chains.
  • The loss of mangrove ecosystems is far more than just an environmental concern. It directly erodes natural infrastructure that serves as a vital buffer for urban coastlines, underpins thriving fisheries, and contributes billions through essential ecosystem services and the prevention of damage. 
• Ecosystem Services: The economic and ecosystem services provided by mangroves are substantial. For instance, the Pichavaram mangrove ecosystem in Tamil Nadu is valued at ₹3,535 million, while the Sundarbans in West Bengal holds an astonishing value of ₹664 billion.

Measures to Protect Mangrooves

Therefore, businesses, governments, and communities must urgently reimagine these ecosystems as active drivers of sustainable growth and long-term security. Achieving this requires a multi-faceted approach, underpinned by three crucial pillars:

• Mapping with Technology:
  • Embracing technology is fundamental to accurately understanding and quantifying the “Natural Capital” that mangroves represent.
  • Advanced tools like satellite and drone data, combined with Artificial Intelligence (AI) algorithms, significantly improve the accuracy of mangrove mapping and blue carbon quantification. This precise data is essential for informing effective policies and targeted restoration efforts.
• Involving Communities:
  • Community-led conservation efforts are key to forging symbiotic and mutually respectful relationships between people and nature.
  • Fisherfolk, in particular, deeply value mangroves for their critical role as nurseries for juvenile fish, ensuring robust fish stocks and sustainable catches. The livelihoods of these coastal communities are intrinsically linked to the health and quality of mangrove and estuarine systems.
  • In dense urban areas such as Mumbai and Chennai, mangroves are often in distress, suffering from pollution and degradation. 
  • When communities directly experience the benefits (e.g., more fish, cleaner air, protected homes) and are empowered to make decisions about their local environment, they become effective and enduring stewards of these vital ecosystems.
  • Integrated ownership models, like Eco-Development Committees (EDCs) or Joint Forest Management Committees (JFMCs), should be adapted and implemented for urban mangroves to foster this community participation.
• Citizen Science:
  • Citizen science actively engages a wide range of stakeholders to generate interest and investment in these undervalued ecosystems, thereby mobilising collective action for their conservation that can effectively supplement or even substitute formal monitoring efforts.
  • The health of mangroves is intrinsically linked to the vitality of associated wetlands and the health of rivers from their source to the sea, as these supply essential freshwater, sediments, and biota. Regular monitoring provides crucial indicators of the system’s well-being.
  • Key indicators for a mangrove health assessment tool must include changes in mangrove area, the quantity, quality, and timing of freshwater flows, the diversity of avian, floral, molluscan, and fish species, and critically, the level of community dependence and their perception of the ecosystem services. Such assessments provide vital insights for management actions.
  • Engagement platforms, such as “Mangrove Mitras” or “Friends of Mangroves”, are crucial for enabling urban citizens and local communities to constructively participate in mangrove conservation. These initiatives help rebuild the vital ‘people-wetland-river-mangrove connection’ through immersive experiences that reveal the magical value of these ecosystems.

Conclusion

• Mangrove stewardship is a shared responsibility. Seen as vital climate and economic assets, their protection needs collaboration between science, business, and communities for a resilient future.
