Scientists and environmentalists are demanding clarifications regarding the No Objection Certificate (NOC) granted for drilling operations in the Krishna delta region. Their primary concerns revolve around the potential for groundwater depletion, increased seismic activity, and overall ecological damage to the fragile delta ecosystem. The Krishna delta is a crucial agricultural and ecologically sensitive zone, making any industrial activity there subject to intense scrutiny.
This incident underscores the tension between energy exploration and environmental protection, highlighting the importance of robust Environmental Impact Assessments (EIAs) and transparent regulatory processes. The demand for clarity reflects a broader concern about balancing developmental needs with the imperative of sustainable resource management, especially in vulnerable coastal and deltaic regions.

Evolution of Environmental Regulations & EIA in India (1984-2025)
This timeline illustrates the key milestones in India's environmental regulatory framework, particularly focusing on the evolution of Environmental Impact Assessment (EIA) and Environmental Clearance (EC) processes. It provides context for the ongoing demand for clarity on NOCs in sensitive regions like the Krishna Delta.
India's environmental regulatory framework has evolved significantly since the Bhopal Gas Tragedy, with the EPA 1986 and subsequent EIA Notifications forming its backbone. The current demand for clarity on NOCs reflects persistent challenges in ensuring transparent and effective environmental governance, especially in the context of rapid industrialization and resource extraction.
- 1984Bhopal Gas Tragedy: Highlighted gaps in environmental laws.
- 1986Environment (Protection) Act (EPA) enacted: Umbrella legislation for environmental protection.
- 1994First EIA Notification under EPA: Made Environmental Clearance (EC) mandatory for 29 categories of projects.
- 2006EIA Notification 2006: Superseded 1994, streamlined process, categorized projects (A & B), introduced public consultation.
- 2010National Green Tribunal (NGT) Act: Established NGT for effective and expeditious disposal of cases relating to environmental protection.
- 2018Launch of PARIVESH portal: Digitization of EC/Forest Clearance process for ease of doing business.
- 2020Draft EIA Notification 2020 proposed: Controversial changes like post-facto clearance, reduced public consultation. Faced widespread criticism.
- 2024Ongoing debates on EIA reforms: Focus on balancing development with environmental protection, strengthening compliance.
- 2025Krishna Delta Drilling Controversy: Scientists demand clarity on NOC/EC, underscoring need for robust EIA and transparent processes.

पृष्ठभूमि
The Krishna Delta, located on India's east coast, is a highly fertile and ecologically sensitive region. It is known for its rich biodiversity, extensive agricultural lands, and significant fishing activity. Historically, deltaic regions have been centers of human habitation and economic activity due to their resource richness.
However, they are also inherently fragile ecosystems, susceptible to environmental changes and anthropogenic pressures. The demand for energy resources has led to increased exploration activities in such regions, often creating a conflict between developmental goals and environmental conservation.

Scientists and environmentalists are currently raising concerns over the No Objection Certificate (NOC) granted for drilling operations in the Krishna delta. The primary apprehensions include potential groundwater depletion, increased seismic activity, and broader ecological damage.
This highlights the ongoing tension between the nation's energy security needs and the imperative to protect vulnerable ecosystems. The incident underscores the critical role of robust Environmental Impact Assessments (EIAs) and transparent regulatory processes in ensuring sustainable development.
बहुविकल्पीय प्रश्न (MCQ)
1. With reference to Environmental Impact Assessment (EIA) in India, consider the following statements: 1. The EIA process is legally backed by the Environment (Protection) Act, 1986. 2. Public hearing is a mandatory stage for all types of projects requiring environmental clearance. 3. The Expert Appraisal Committee (EAC) is responsible for screening and scoping projects based on their potential impact. Which of the statements given above is/are correct?
उत्तर देखें
सही उत्तर: B
Statement 1 is correct. The EIA process in India derives its legal validity from the Environment (Protection) Act, 1986, specifically through the EIA Notification, 2006 (and subsequent amendments). Statement 2 is incorrect. Public hearing is not mandatory for all projects. Certain categories of projects, such as those related to national defence, security, or specific small-scale projects, are exempted from public hearing. Also, some projects are exempted if they are located in industrial estates or have minimal environmental impact. Statement 3 is correct. The Expert Appraisal Committee (EAC) at the central level and State Expert Appraisal Committee (SEAC) at the state level are crucial bodies responsible for screening, scoping, and appraisal of projects to determine their potential environmental impacts and recommend environmental clearance.
2. Consider the following statements regarding the Krishna Delta and other major deltas in India: 1. The Krishna Delta is characterized by extensive mangrove forests and is a significant nesting site for Olive Ridley turtles. 2. Unlike the Ganga-Brahmaputra Delta, the Krishna Delta is primarily formed by a single river system. 3. The Mahanadi Delta, similar to the Krishna Delta, is known for its rich agricultural productivity and aquaculture. Which of the statements given above is/are correct?
उत्तर देखें
सही उत्तर: C
Statement 1 is correct. The Krishna Delta, particularly the Krishna Wildlife Sanctuary, is known for its extensive mangrove forests and is indeed an important nesting ground for Olive Ridley sea turtles. Statement 2 is incorrect. While the Krishna Delta is primarily formed by the Krishna River, the Godavari River also forms a significant delta adjacent to it, and together they are often referred to as the Krishna-Godavari (KG) Delta. The Ganga-Brahmaputra Delta is formed by the confluence of multiple major river systems (Ganga, Brahmaputra, Meghna). Statement 3 is correct. The Mahanadi Delta, located further north on the east coast, is also highly fertile, supporting extensive agriculture and aquaculture, similar to the Krishna Delta.
3. In the context of industrial activities like drilling in deltaic regions, which of the following statements correctly describes potential environmental impacts? 1. Groundwater depletion can occur due to direct extraction for industrial processes and alteration of aquifer systems. 2. Induced seismicity is primarily caused by the release of natural tectonic stress through drilling operations. 3. Saline water intrusion into freshwater aquifers is a common consequence of excessive groundwater extraction in coastal deltas. Select the correct answer using the code given below:
उत्तर देखें
सही उत्तर: B
Statement 1 is correct. Industrial drilling operations often require significant amounts of water, leading to direct groundwater extraction. Additionally, drilling can alter the geological structure, potentially disrupting natural aquifer recharge and flow, contributing to depletion. Statement 2 is incorrect. Induced seismicity refers to earthquakes and tremors caused by human activity. While drilling can trigger seismic events, it's not primarily due to the 'release of natural tectonic stress' in that manner. Instead, it's often linked to changes in pore pressure in rocks due to fluid injection (e.g., wastewater disposal, hydraulic fracturing) or fluid extraction (e.g., oil/gas extraction, geothermal energy production), which can lubricate faults or alter stress fields. The news mentions 'increased seismic activity' as a concern, which points to induced seismicity. Statement 3 is correct. In coastal deltaic regions, freshwater aquifers are often in hydraulic balance with the adjacent seawater. Excessive extraction of groundwater reduces the water table, allowing the denser saline water from the sea to intrude into the freshwater aquifers, rendering them unusable.
