The Scientist who made ‘mangroves’ a buzzword

Why in the News?

• World Mangrove Day is celebrated on July 26 to raise awareness about the importance of mangrove ecosystems.
• The 2023 India State of Forest Report (ISFR) highlights a rise in India’s mangrove cover, reflecting decades of conservation and restoration efforts inspired by M.S. Swaminathan.
• Selvam Vaithilingam, former Executive Director at the M.S. Swaminathan Research Foundation, highlights Swaminathan’s pioneering role in mangrove management, conservation science, and coastal climate resilience.

Background

• Until the 1980s, mangroves were undervalued, mostly by communities that directly depended on them for fisheries and livelihoods.
• Their ecological, economic, and climate value was not yet fully recognised in mainstream environmental policy.
• A turning point came in 1989 when M.S. Swaminathan proposed the critical role of mangroves in climate adaptation at a Tokyo climate conference.
• He connected rising sea levels, increased cyclones, and salinisation of coastal land with the urgent need to conserve mangrove ecosystems.

Feature

Global Contributions of M.S. Swaminathan:

• 1989: Advocated mangrove conservation as a climate adaptation strategy.
• 1990: Helped establish the International Society for Mangrove Ecosystems (ISME) in Okinawa, Japan. He served as its Founding President.
• 1992: Co-authored the Mangrove Charter, later part of the UN World Charter for Nature.
• Pioneered global assessments, workshops, manuals, and the World Mangrove Atlas.

Knowledge Infrastructure:

• Developed GLOMIS (Global Mangrove Database and Information System).
• Contributed to the creation of Mangrove Genetic Resource Centres across 9 Asian-Pacific countries, many now protected areas.

National-Level Achievements:

• Challenged colonial-era mangrove management policies that focused on clear-felling.
• Led participatory research with local communities and forest departments.
• The fishbone canal method (a hydro-ecological restoration model) was introduced and tested in Tamil Nadu, Odisha, Andhra Pradesh, and West Bengal.
• This led to the Joint Mangrove Management adopted by the Ministry of Environment and Forests and scaled nationally.

Disaster Risk Reduction:

• 1999 Odisha Super Cyclone and the 2004 Tsunami demonstrated the protective power of mangroves.
• Their presence helped reduce loss of life and property, influencing large-scale investment in mangrove regeneration.

Scientific Recognition and Outcomes:

• Mangroves are now viewed as:
  • Carbon sinks (for climate mitigation)
  • Buffers against extreme weather
  • Biodiversity hotspots
  • Crucial for coastal fishery productivity
• ISFR 2023 notes:
  • India has 4,991.68 km² of mangrove cover (0.15% of geographical area).
  • An increase of 16.68 km² compared to ISFR 2019.

Challenge

Legacy of Mismanagement:

• Colonial and post-independence forest policies promoted mangrove clearance for agriculture and settlement.
• Blaming local communities for poor restoration outcomes ignores deeper ecological mismanagement.

Climate Change Pressures:

• Sea level rise, salinity intrusion, and coastal erosion continue to threaten mangrove ecosystems.

Development vs. Conservation:

• Infrastructure and tourism projects often override ecological priorities in coastal areas zones.

Knowledge & Coordination Gaps:

• Fragmented institutional efforts, lack of trained personnel, and inadequate community involvement limit effective conservation.

Encroachment and Pollution:

• Rapid urbanisation, aquaculture, and industrial waste are degrading several mangrove areas, especially near estuaries and deltas.

Way Forward

Mainstream Mangrove Thinking:

• Integrate mangrove conservation into coastal urban planning, disaster risk reduction, and climate policy frameworks.

Community-Based Restoration:

• Expand Joint Mangrove Management models, incentivising local community participation.

Scientific Innovation:

• Use genomic tools for developing salinity-tolerant crops from mangrove species (as initiated by Swaminathan).
• Strengthen ecological monitoring, especially with remote sensing and GIS tools.

Legal and Policy Strengthening:

• Ensure strict CRZ (Coastal Regulation Zone) enforcement.
• Mandate Mangrove Impact Assessments before approving coastal development projects.

Education and Awareness:

• Promote mangrove literacy in school curricula and public campaigns.
• Highlight success stories like Odisha and Tamil Nadu’s coastal restoration for replication.

International Collaboration:

• Reinvigorate platforms like ISME, GLOMIS, and the World Mangrove Charter for South-South cooperation and knowledge exchange.

Conclusion

M.S. Swaminathan’s pioneering vision transformed mangroves from “marshy wastelands” into climate warriors of the coastline. His advocacy and scientific leadership built global and national institutions that have changed how mangroves are perceived, conserved, and restored. As India sees a rise in mangrove cover and celebrates World Mangrove Day, his legacy offers a roadmap for equity-led, ecology-rooted, and economically sound coastal development.
