Which one of the following has been constituted under the Environment (Protection) Act, 1986?
Central Ground Water Authority (CGWA) has been constituted under Section 3 (3) of the Environment (Protection) Act, 1986 to regulate and control development and management of groundwater resources in the country. Central Water Commission (CWC) - Established in 1945, the CWC is a technical organization under the Ministry of Jal Shakti. It focuses on water resource planning, development, and management in India, but its legal basis comes from other central government acts. Central Ground Water Board (CGWB) - While it works in close collaboration with the CGWA, the CGWB is a subordinate organization under the Ministry of Jal Shakti, established in 1970. It functions as the technical arm of the CGWA, providing hydrogeological data and technical expertise. National Water Development Agency (NWDA) - This autonomous agency, established in 1982 under the Ministry of Jal Shakti, operates under the Societies Registration Act, 1860. It focuses on resolving interstate water resource disputes, conducting feasibility studies for water resource development projects, and planning water transfer and linking projects.
Consider the following statements:
1. 36% of India’s districts are classified as “overexploited” or critical” by the Central Ground Water Authority (CGWA).
2. CGWA was formed under the Environment (Protection) Act.
3. India has the largest area under groundwater irrigation in the world.
Which of the statements given above is/are correct?
Statement 1 is incorrect: As per the report National Compilation on Dynamic Groundwater Resources of India, 2017 of CGWA, out of the total 6881 assessment units (Blocks/Mandals/ Talukas) in the country, 1186 units in various States (17%) have been categorized as Over-Exploited, 313 units (5%) as Critical, and 972 units (14%) as Semi-Critical. Statement 2 is correct: The CGWA was established in 1997 under Section 3(3) of the Environment (Protection) Act, 1986 to regulate and manage groundwater resources. Statement 3 is correct: India has the largest area under groundwater irrigation in the world. This is due to the country's heavy reliance on agriculture, which is predominantly rain-fed. Therefore, the correct answer is B. 2 and 3 only.
Consider the following statements :
The Environment Protection Act, 1986 empowers the Government of India to
1. state the requirement of public participation in the process of environmental protection, and the Procedure and manner in which it sought
2. lay down the standards for emission or discharge of environmental pollutants from various sources
Which of the statements given above is/are correct?
Statement 1 is incorrect: The Environment Protection Act (EPA), 1986 recognizes the importance of public participation in environmental decision-making. However, it does not explicitly define the procedure for public participation in environmental governance, such as public hearings or consultations. These provisions were later formalized through subsequent rules and notifications, such as the Environmental Impact Assessment (EIA) Notification, 2006, which mandates public hearings for certain projects. Statement 2 is correct: The EPA, of 1986 empowers the Central Government to Lay down environmental quality standards for air, water, and soil, Regulate emissions and discharges of pollutants from industries and other sources, Restrict hazardous substances and their handling, Take emergency measures to prevent environmental disasters.
With reference to ‘Eco-Sensitive Zones’, which of the following statements is/are correct?
1. Eco-Sensitive Zones are the areas that are declared under the Wildlife (Protection) Act, 1972.
2. The purpose of the declaration of Eco-Sensitive Zones is to prohibit all kinds of human activities, in those zones except agriculture.
Select the correct answer using the code given below.
Statement 1 is incorrect: Eco-Sensitive Zones are not under the Wildlife (Protection) Act, of 1972. They are notified by the Ministry of Environment, Forest and Climate Change (MoEFCC) under the Environment (Protection) Act, 1986. While they often surround protected areas like wildlife sanctuaries and national parks established under the Wildlife Act, they are a separate mechanism. Statement 2 is incorrect: Eco-Sensitive Zones do not prohibit all human activities. The purpose is to regulate and manage specific activities to minimize their impact on the sensitive ecosystem. Some sustainable activities like agriculture, local communities' traditional practices, and eco-tourism may be permitted with regulations.
Which of the following statements in relation to NIRANTAR (National Institute for Research and Application of Natural Resources to Transform, Adapt and Build Resilience), a platform of institutions under the Ministry of Environment, Forest and Climate Change, is/are correct ?
1. Ecosystem Survey and Analysis is a vertical under this platform, the lead institute of which is Botanical Survey of India, Kolkata.
2. Research and Management of Ecosystem Service is a vertical under this platform, the lead institute of which is Central Zoo Authority, New Delhi.
3. Capacity Development Support is a vertical under this platform, the lead institute of which is Indian Institute of Forest Management, Bhopal.
Select the answer using the code given below :
Statement 1 is Correct: The National Institute for Research and Application of Natural Resources to Transform, Adapt and Build Resilience (NIRANTAR) is a collaborative platform under the Ministry of Environment, Forest and Climate Change (MoEFCC). Ecosystem Survey & Analysis is one of its four thematic verticals, and its lead institute is the Botanical Survey of India (BSI), Kolkata. Statement 2 is Incorrect: The Research and Management of Ecosystem Service vertical is led by the Indian Council of Forestry Research and Education (ICFRE), Dehradun, not the Central Zoo Authority (CZA). The CZA is merely a participating institute under this vertical. Statement 3 is Correct: The Capacity Development Support vertical focuses on research, education, and capacity building. The lead institute for this vertical is the Indian Institute of Forest Management (IIFM), Bhopal. Therefore, option B is the correct answer.
