From UPSC perspective, the following things are important :
Prelims level : CRZ
Mains level : Sea level rise and threats to coastal cities
The Brihanmumbai Municipal Corporation (BMC) inspected a bungalow owned by a Union Minister for alleged violation of Coastal Regulation Zone (CRZ) norms.
What is the news?
- The Union Minister’s bungalow named has been illicitly constructed within 50 metres of the sea in violation of the CRZ rules.
- The crackdown assumes significance in the escalating verbal spats between the two political rivals (which were allies for years).
What are CRZ norms?
- In India, the CRZ Rules govern human and industrial activity close to the coastline, in order to protect the fragile ecosystems near the sea.
- They restrict certain kinds of activities — like large constructions, setting up of new industries, storage or disposal of hazardous material, mining, reclamation and bunding — within a certain distance from the coastline.
- After the passing of the Environment Protection Act in 1986, CRZ Rules were first framed in 1991.
- After these were found to be restrictive, the Centre notified new Rules in 2011, which also included exemptions for the construction of the Navi Mumbai airport and for projects of the Department of Atomic Energy.
- While the CRZ Rules are made by the Union environment ministry, implementation is to be ensured by state governments through their Coastal Zone Management Authorities.
Where do they apply?
- In all Rules, the regulation zone has been defined as the area up to 500 m from the high-tide line.
- The restrictions depend on criteria such as the population of the area, the ecological sensitivity, the distance from the shore, and whether the area had been designated as a natural park or wildlife zone.
- The latest Rules have a no-development zone of 20 m for all islands close to the mainland coast, and for all backwater islands in the mainland.
New Rules under CRZ regulations
- The government notified new CRZ Rules with the stated objectives of promoting sustainable development and conserving coastal environments.
- For the so-called CRZ-III (Rural) areas, two separate categories have been stipulated.
- In the densely populated rural areas (CRZ-IIIA) with a population density of 2,161 per sq km as per the 2011 Census, the no-development zone is now 50 m from the high-tide level, as against the 200 m stipulated earlier.
- In the CRZ-IIIB category (rural areas with population density below 2,161 per sq km) continue to have a no-development zone extending up to 200 m from the high-tide line.
- The new Rules have a no-development zone of 20 m for all islands close to the mainland coast, and for all backwater islands in the mainland.
