Supreme Court Censures Maharashtra Government
Key Highlights on Afforestation Issues in Mumbai
Constitutional and Legal Context
- The Supreme Court (SC) of India has emphasized accountability in environmental governance, specifically over the tree felling policies related to urban development in Mumbai, highlighting the state's responsibility under the Constitution to protect and improve the environment (Article 48A - Protection and Improvement of Environment, Article 51A(g) - Fundamental Duties).
Judicial Rulings and Warnings
- The SC criticized the Maharashtra government for its poor afforestation survival rates, threatening to revoke permissions granted for various city projects if conditions do not improve. This includes projects like the Mumbai Metro Rail and the Goregaon-Mulund Link Road (GMLR).
- A previous order from August 14 allowed the felling of 95 trees for the GMLR, contingent on compensatory afforestation efforts.
- The court directed the Maharashtra Chief Secretary to prepare a concrete proposal for compensatory afforestation to ensure that it is strictly adhered to.
Afforestation Data and Survival Rates
- According to the Brihanmumbai Municipal Corporation (BMC), from 2018 to 2023, 21,028 trees were felled for development projects, but only 50% of 20,460 trees planted as compensatory measures for previous projects survived.
- In the same period, 21,916 mature trees were transplanted, with a survival rate of just 21% (only 963 trees survived).
- The next phase of the Mumbai Coastal Road project plans to fell an additional 1,244 trees, with 706 more slated for the construction of a high-speed corridor.
Factors Contributing to Low Survival Rates
- Transplantation Issues: Experts indicate that the haphazard and unscientific methods employed in the transplantation process, such as inadequate recovery times after uprooting, and relocating trees far from their original sites, contribute significantly to low survival rates.
- Tree Species: The predominance of hardwood species (e.g., mango, teak) for transplantation, which generally have lower survival rates compared to softwood species (e.g., gulmohar, banyan), exacerbates the situation.
- Environmental Conditions: Mumbai’s coastal geography, increased pollution, and the stress of urbanization on the natural habitat hinder survival.
Proposed Government Measures and Community Involvement
- The Maharashtra government has been asked to convene a meeting with stakeholders to discuss actionable measures for improving the success rate of afforestation initiatives.
- Authorities need to adhere to established protocols regarding the transport and care of transplanted trees, ensuring that they are adequately watered and tended to immediately after relocation.
Conclusion
- The current judicial scrutiny reflects a growing demand for better environmental management from urban development projects in India, underlining the critical need for sustainable forestry practices and accountability in the handling of urban ecosystems.
