Livelihood of Mumbai fishers at risk as mangroves make way for road

Why in News?

Large-scale diversion of mangrove forests for the Versova–Bhayandar Coastal Road project in Mumbai has raised concerns regarding ecological sustainability and the livelihood security of coastal fishing communities.

Mangroves: Ecological Profile

Mangroves are salt-tolerant forest ecosystems found in intertidal coastal zones. In India, they are distributed across the eastern and western coasts and island territories.

They play a crucial role in:

• Supporting marine biodiversity through nursery and breeding habitats
• Protecting coastlines from erosion, storm surges, and flooding
• Acting as significant carbon sinks (blue carbon ecosystems)

The Issue: Coastal Infrastructure vs Ecological Stability

The proposed coastal road project aims to improve connectivity and reduce travel time. However, it involves large-scale removal of mangrove cover, leading to a conflict between infrastructure development and environmental sustainability.

Livelihood Implications

Fishing communities along Mumbai’s coast depend heavily on mangrove ecosystems. These areas sustain fish populations and provide a stable resource base for small-scale fisheries. Loss of mangroves can therefore:

• Disrupt traditional occupations
• Increase economic vulnerability
• Lead to occupational displacement without adequate alternatives

Environmental Concerns

Loss of Ecosystem Services

Mangroves provide multiple ecosystem services such as coastal protection, biodiversity support, and carbon sequestration. Their removal leads to long-term ecological costs that may outweigh short-term infrastructure gains.

Limitations of Compensatory Afforestation

Afforestation efforts often fail to replicate the ecological complexity of natural mangroves due to:

• Use of limited or non-native species
• Poor site selection
• High mortality rates

Thus, compensatory measures may not adequately substitute the ecological functions lost.

Increased Climate Vulnerability

Mumbai is highly vulnerable to sea-level rise and extreme weather events. Reduction in mangrove cover weakens natural coastal defence mechanisms, increasing the risk of flooding and damage.

Governance and Planning Challenges

Public Participation Deficit

Concerns have been raised about inadequate consultation with affected communities, particularly traditional fisher groups. This raises issues of procedural fairness and participatory governance.

Limitations in Environmental Impact Assessment

Environmental Impact Assessment processes are often criticised for:

• Insufficient evaluation of cumulative and long-term impacts
• Inadequate incorporation of local ecological knowledge

Urban Planning Concerns

The prioritisation of road-based infrastructure reflects a broader challenge in urban planning, where ecological considerations and sustainable transport alternatives are not sufficiently integrated.

Judicial Approach

Courts have permitted the project subject to compensatory measures such as afforestation. This reflects an attempt to balance development needs with environmental protection, though questions remain regarding the adequacy of such safeguards.

Way Forward

1. Integrating Ecosystem-Based Planning

Urban infrastructure planning must adopt an ecosystem-based approach, wherein natural features such as mangroves are treated as integral components of urban resilience. Spatial planning tools, including coastal zone mapping and vulnerability assessments, should guide project design to minimise ecological disruption.

2. Strengthening Environmental Impact Assessment Framework

The EIA process should be made more rigorous by incorporating:

• Comprehensive cumulative impact assessments
• Independent expert review mechanisms
• Greater transparency in data and decision-making

This would ensure that environmental costs are properly evaluated before project approval.

3. Ensuring Meaningful Stakeholder Participation

Consultation processes should go beyond procedural compliance and involve genuine engagement with affected communities. Mechanisms such as social impact assessments and participatory planning can help incorporate local concerns and knowledge into decision-making.

4. Livelihood Protection and Rehabilitation

A structured rehabilitation framework is necessary for affected fisher communities, including:

• Fair and timely compensation
• Skill development and alternative livelihood opportunities
• Recognition of traditional rights and dependence on coastal ecosystems

5. Promoting Sustainable Urban Transport

Urban transport policy should prioritise:

• Expansion of public transport systems
• Multimodal connectivity
• Reduction of dependence on private vehicles

This can reduce the need for ecologically disruptive infrastructure projects.

6. Scientific Mangrove Conservation and Restoration

Mangrove conservation efforts should focus on:

• Protection of existing natural ecosystems
• Restoration using native species and site-specific ecological conditions
• Long-term monitoring of survival and ecological functionality

Conclusion

The conflict between coastal infrastructure development and mangrove conservation highlights the need for a balanced approach that integrates ecological sustainability with developmental objectives. Protecting mangroves is essential not only for environmental reasons but also for safeguarding livelihoods and enhancing urban resilience in the face of climate change.
