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.

It is responsible for the implementation of Project Tiger. Statement 3 is correct: The National Ganga River Basin Authority (NGRBA) was constituted under the Environment (Protection) Act, 1986 and was chaired by the Prime Minister. It aimed to plan and coordinate measures for the conservation and management of the Ganga River. (It was later replaced by the National Ganga Council in 2016.)
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.
