National Centre for Sustainable Coastal Management (NCSCM) – Wetland Verification and Conservation

Why is it in the News ?

• Recently, the National Centre for Sustainable Coastal Management (NCSCM) completed the documentation, satellite-based mapping, and ground-truthing of 23,404 wetlands out of Maharashtra’s total 23,415 wetlands. Only 11 wetlands, mainly located in Pune district, are still undergoing field verification. 
• With the completion of this process, these wetlands can now be notified under the Wetlands (Conservation and Management) Rules, 2017, enabling them to receive formal legal protection. Experts consider this a major step toward conserving Maharashtra’s wetland ecosystems and strengthening climate change adaptation measures. 

What is Ground-truthing ?

Ground-truthing is a scientific and administrative process involving on-site inspection and verification of wetlands to establish consistency between satellite imagery, remote sensing data, and actual field conditions.

The process includes the following assessments :

1. Determination of Actual Existence and Area of Wetlands

• Verification of whether the water body identified in satellite images actually exists and assessment of its real extent. 

2. Boundary Delineation

• Identification of geographical boundaries, water spread area, and surrounding land-use patterns. 

3. Assessment of Ecological Condition

• Evaluation of vegetation cover, biodiversity, water quality, and ecological health. 

4. Assessment of Land Use and Human Interference

• Examination of encroachments, land filling, construction activities, and other anthropogenic pressures. 

5. Validation of Satellite Data

• Matching remote sensing and GIS-based information with actual ground conditions. 

Ground-truthing is considered essential because wetlands cannot be officially notified under environmental regulations without field verification.

About the National Centre for Sustainable Coastal Management (NCSCM)

The National Centre for Sustainable Coastal Management (NCSCM) was established in 2011 by the Ministry of Environment, Forest and Climate Change (MoEFCC) as an autonomous research and policy institution.

Its objective is to support the conservation, sustainable utilization, restoration, and scientific management of India’s coastal and marine ecosystems.

Headquarters : Chennai, Tamil Nadu

Objectives and Functions of NCSCM

Promoting Coastal Conservation and Sustainable Development

• Works to maintain environmental balance and ensure long-term conservation of coastal resources. 

Integrated Management of Coastal and Marine Areas

• Supports the implementation of Integrated Coastal Zone Management (ICZM) in India. 

Protection of Socio-economic Interests of Coastal Communities

• Provides policy support while considering livelihoods and welfare of traditional coastal and island communities. 

Scientific and Policy Support to Governments

• Offers technical guidance to central and state governments on coastal management and environmental protection. 

Research and Capacity Building

• Conducts studies on coastal resources, marine ecology, and climate change impacts. 

Major Research Divisions of NCSCM

1. Geospatial Sciences, Remote Sensing and GIS Division

• Undertakes satellite mapping, geospatial analysis, coastal mapping, and wetland documentation. 

2. Integrated Social Sciences and Economics Division

• Studies socio-economic conditions, livelihoods, and resource use patterns of coastal communities. 

3. Coastal Environmental Impact Assessment Division

• Evaluates the ecological impacts of developmental activities on coastal ecosystems. 

4. Coastal and Marine Resource Conservation Division

• Focuses on conservation of marine biodiversity, coral reefs, mangroves, and marine ecosystems. 

5. Knowledge, Governance and Policy Division

• Strengthens policy formulation, institutional coordination, and environmental governance. 

6. Foresight Research and Integrated Island Management Unit

• Conducts research on climate change, island ecosystems, and long-term coastal management strategies. 

Ecological Importance of Wetlands

Wetlands are regarded as among the most productive ecosystems on Earth because they provide multiple ecological services.

Flood Buffering

• Store excess rainwater and reduce flood intensity in urban and rural areas. 

Natural Drainage System

• Function as natural drainage networks and help control waterlogging. 

Groundwater Recharge

• Support groundwater replenishment and improve water availability. 

Carbon Sequestration

• Absorb and store carbon, contributing to climate change mitigation. 

Biodiversity Conservation

• Provide habitats for migratory birds, aquatic organisms, and diverse vegetation. 

Climate Change Adaptation

• Help reduce the impacts of extreme rainfall, sea-level rise, and extreme weather events. 

Way Forward

• Expedite notification of verified wetlands. 
• Ensure legal protection and prevent encroachments. 
• Integrate wetlands into urban planning as natural drainage systems. 
• Prioritize wetland conservation in climate change policies. 
• Promote community participation for sustainable conservation models.
