Context
The Union government informed the Lok Sabha that 43% of trees (1,545 out of 3,609) transplanted for the Central Vista redevelopment projects have perished. This data, provided in response to a question, highlights significant challenges in the execution of environmental mitigation strategies for large-scale urban infrastructure projects. As compensation, over 26,000 new trees have been planted elsewhere, funded by a budget of Rs. 5.29 crore for transplantation and compensatory plantation from 2023-2026.
UPSC Perspectives
Environmental
This incident raises critical questions about the effectiveness of tree transplantation as a mitigation tool for biodiversity loss in urban development. The low survival rate of 43% indicates that transplantation is not a simple substitute for in-situ conservation. Ecologically, mature trees are part of a complex ecosystem, supporting a wide array of organisms and providing significant environmental services like carbon sequestration, air purification, and temperature regulation, which saplings cannot immediately replace. The legal framework governing this is primarily the , which mandates permission for felling and encourages transplantation. Delhi's Tree Transplantation Policy, 2020, even sets a target of 80% survival, which has clearly not been met in this high-profile project. The policy of compensatory afforestation (planting new trees, often in a different location, to compensate for forest land diverted for non-forest purposes) is also central here, governed by the . While new plantations are mandated, the ecological value of a lost, mature tree is not immediately compensated by planting a sapling. UPSC aspirants should analyze the debate on development vs. conservation, using this as a case study to argue for stronger Environmental Impact Assessment (EIA) protocols that critically evaluate the feasibility and success rate of such mitigation measures before granting clearance.
Governance
The high failure rate in tree transplantation points to a significant governance deficit in project implementation and monitoring. The , managed by the Central Public Works Department (CPWD), is a flagship initiative, and failures in its execution reflect on the state's capacity for sustainable development. This data, revealed in Parliament, underscores the importance of legislative oversight and accountability mechanisms. It questions the technical expertise and post-transplantation care protocols employed by the implementing agencies. The , prohibits the use of forest land for non-forest purposes without central government approval, promoting conservation. While the Central Vista area may not be 'forest land' in the legal sense, the principles of the Act—prioritizing conservation—are relevant. This case highlights a potential gap between policy intent (e.g., Delhi's transplantation policy) and on-ground reality, which could be due to lack of specialized skills, inadequate monitoring, or insufficient funding for after-care. For Mains, this can be linked to topics like performance auditing of government projects and the need for a robust, technology-enabled, and transparent monitoring framework for environmental commitments made during project approval.
Economic
From an economic perspective, this issue highlights the concept of negative externalities and the undervaluation of natural capital. The loss of 43% of transplanted trees represents a direct waste of public funds (part of the Rs. 5.29 crore spent) and an indirect economic loss from the degradation of ecosystem services. These services, such as clean air, groundwater recharge, and urban cooling, have a tangible economic value but are often not factored into project costs, a classic market failure. The principle of Net Present Value (NPV) is used in calculating compensation for forest diversion, attempting to monetize the future services of a forest. The failure of transplanted trees means the NPV of the lost ecological services is not being adequately compensated. This situation underscores the importance of the 'polluter pays' principle and the need to internalize environmental costs into project budgets. Students can use this example to discuss the limitations of cost-benefit analysis in infrastructure projects when ecological costs are not properly quantified and mitigation strategies are assumed to be 100% successful. It also feeds into the larger discourse on 'green accounting' and integrating environmental sustainability into economic planning to achieve long-term development goals.
