The Supreme Court of India issued a significant ruling on May 22, 2025, regarding approximately 86,000 hectares of Zudpi jungle lands, primarily located in Maharashtra's eastern Vidarbha region. This decision sought to clarify the legal status of these lands, recognizing them as "forest" lands, and imposing stringent conditions for their use and conversion.

Summary of Key Points:

• Legal Classification of Zudpi Lands:

  • Zudpi, a term derived from Marathi, refers to bushy or inferior unoccupied land in eastern Vidarbha, specifically covering six districts: Nagpur, Chandrapur, Gadchiroli, Bhandara, Wardha, and Gondia.
  • These lands have historically been used for non-forest purposes, including grazing, infrastructure, and community projects, and were classified as Gairan under the Maharashtra Land Revenue Code, 1966.

• Challenging Legal Status:

  • The ambiguity surrounding the status of Zudpi lands persisted due to inconsistent government actions and bureaucratic inaction since they were initially categorized as ‘scrub forests’ in a 1987 order, which exempted them from the provisions of the Forest (Conservation) Act, 1980.
  • The 1987 order was contested in court, leading to various interpretations of forest laws, including a decisive judgment in the ‘TN Godavarman Thirumulpad’ case (1996) which recognized Zudpi lands as forest lands under the FCA.

• Supreme Court’s Ruling:

  • The Supreme Court determined that Zudpi lands are to be deemed forest lands, especially cautioning against conversion without prior central approval.
  • The ruling stipulates that exceptions are made for lands granted for non-forest usage before December 12, 1996, where the state must seek central approval without imposing compensatory afforestation conditions.
  • The court ordered that no lands should be diverted for non-government use and that post-1996 allotments would require thorough scrutiny to ensure compliance with established directives.

• Implementation Measures:

  • Special Task Forces within each district are to address encroachments on Zudpi lands after a defined date (October 25, 1980), with commercial allotments post-October 25, 1989, classified as encroachments.
  • The Supreme Court instructed the Revenue Department to transfer remaining Zudpi lands to the Forest Department within one year, facilitating afforestation efforts.

• Government and Environmental Concerns:

  • The Maharashtra government contended that Zudpi lands should not be treated as forest lands, citing administrative lapses in record maintenance.
  • Environmentalists opposed the de-notification of lands, warning of potential ecological harm to wildlife corridors and urge compliance with conservation efforts.

• Expected Outcomes:

  • The ruling is seen as a boost for the planned infrastructure and development works in Vidarbha, provided the state secures approvals for land use from the central government.
  • There is a requirement for the Central Empowered Committee (CEC) to monitor the compliance and implementation of the Supreme Court's directives.

• Constitutional and Legal Context:

  • The ruling interconnects with various legal frameworks including the Forest (Conservation) Act, 1980, and the Maharashtra Land Revenue Code, 1966, allowing for a reevaluation of land use and management while balancing ecological preservation and developmental needs.

This verdict illustrates the judiciary's role in adjudicating on environmental matters while addressing local governance issues and upholding forest law compliance. The Supreme Court aims to achieve a balanced approach, delineating a path for responsible development while safeguarding environmental integrity.

Summary:

Recent research from IIT Kharagpur highlights the critical health impact of ambient air pollution in major Indian cities, attributing 7.2% of annual deaths in these metropolitan areas to poor air quality. As per the study, exposure to airborne particulate matter may reduce the life expectancy of Indians by up to five years. Notably, traffic-related pollution, which significantly exceeds reported levels by urban sensors, accounts for approximately 33% of daily pollution exposure, despite commuting occupying only 8% of an individual's day.

To address the health risks posed by this pollution, researchers Arkopal Kishore Goswami, Kapil Kumar Meena, and Aditya Kumar Singh developed the Dynamic Route Planning for Urban Green Mobility (DRUM) web application. This application is a sophisticated tool akin to Google Maps, designed for users to select their travel routes based on real-time air quality and energy efficiency.

Key Features of DRUM:

• Users can choose from five routing options:
  • Shortest route
  • Fastest route
  • Least Exposure to Air Pollution (LEAP)
  • Least Energy Consumption Route (LECR)
  • A suggested route that balances all factors
• In tests conducted in Delhi, the LEAP option successfully cut pollution exposure by over 50% while extending commuting time by 40%. The LECR option resulted in a 28% reduction in energy consumption in South Delhi.

Despite its promise, the DRUM application faces challenges, primarily related to the insufficiency of air quality monitoring stations—India requires approximately 4,000 continuous air quality stations, but the Central Pollution Control Board (CPCB) has only 1,385 operational by late 2024. Delhi is particularly underserved with only 40 stations, leaving many areas without adequate data. To overcome this, the DRUM team used data from CPCB and the World Air Quality Index, employing interpolative strategies to make estimations in data-sparse zones.

DRUM's technical architecture is built around real-time data collection, ensuring instantaneous updates on air quality and traffic conditions. The system utilizes a GraphHopper library for route generation, supporting various vehicles, and is optimized for speed and functionality.

Moreover, the foundational logic of DRUM prioritizes route selection by first minimizing exposure time and then considering distance and energy consumption. Testing has included simulations across various corridors in Delhi, which revealed that routes deemed shorter or faster often traversed through polluted regions.

Future developments for DRUM include the potential for real-world testing and an enhanced version, DRUM 2.0, which aims to integrate crowdsourced data and machine learning models to provide predictive routing assistance tailored to individual users’ needs. This could significantly broaden the app's applicability beyond conventional vehicles to include micro-mobility options such as bicycles and pedestrian pathways.
