(f) if so, the details thereof along with the future plans to strengthen coastal protection and resilience measures in Andhra Pradesh? ANSWER MINISTER OF STATE IN THE MINISTRY OF ENVIRONMENT, FOREST AND CLIMATE CHANGE (SHRI KIRTI VARDHAN SINGH)

(a) The National Centre for Coastal Research (NCCR), an attached office of the Ministry of Earth Sciences (MoES), has been monitoring shoreline erosion along the Indian coast since 1990 using remote sensing data and GIS mapping techniques. Based on the results of the study, the Annexure provides detailed information on the total length of coastline in the country affected by coastal erosion, State/UT-wise along with identification of district-wise erosion hotspots in Andhra Pradesh and the rate of annual land loss recorded during the last five years.

(b)-(f) The Government of India is committed to taking proactive steps in combating sea erosion and protection of India’s coastal areas. Some of the important measures undertaken in this regard

are as follows:  MoEFCC has issued Coastal Regulation Zone (CRZ) Notifications with a view to conserve and protect the unique environment of coastal stretches and marine areas, 1besides livelihood security to the fisher communities and other local communities in the coastal areas and to promote sustainable development based on scientific principles taking into account the dangers of natural hazards, sea level rise due to global warming.

 As per CRZ Notification, 2019, measures for control of erosion are permissible activity in CRZ areas. The Ministry has issued directions to Coastal States/UTs, for incorporation of Shoreline Management Plan in CZMP. NCSCM, an organization under Ministry of Environment Forest & Climate Change (MoEFCC) and NCCR is providing technical support to coastal States for implementation of coastal protection measures at vulnerable stretches and also involved in the preparation of Shoreline Management Plans.

 MoEFCC has delineated the hazard line for the entire coast of the country. The hazard line is used by agencies in Coastal States as a tool for Disaster Management including planning of adaptive and mitigation measures. The hazard line features in the Coastal Zone Management Plan (CZMP) of the coastal States/Union territories and approved by the MoEFCC.

 Coastal Protection Projects are planned & executed by respective Maritime States/ UTs.

Central Government’s role is largely advisory, technical support and catalytic in nature.

These projects are generally funded by States/ UTs from their own funds or from multilateral funding or through Central Assistance. In some cases, Government of India has facilitated multilateral funding to States/ UTs in tackling the coastal erosion. A Status Report on Coastal Area Management published in 2024 by Central Water Commission noted that the total expenditure incurred by various Maritime States/ UTs for protection of coastal erosion in the last 10 years is ₹ 2641.39 crore and the total cost of planned schemes as well as ongoing works for the next 5 years is ₹ 7218.63 crore.

 Mangrove and shelterbelt plantations also helps in control of coastal erosion. Union Budget 2023-24 announced ‘Mangrove Initiative for Shoreline Habitats & Tangible Incomes (MISHTI)’ to promote and conserve mangroves, which will also work as a bio shield. Under this program, an amount of ₹ 4.71 Crore has been released to the Andhra Pradesh during the FY 2024-25 as Gap-Funding from National CAMPA through MISHTI Scheme  The 15th Finance Commission has recommended ₹ 1000 crore for resettlement of displaced people affected by erosion for 2021- 26 under National Disaster Response Fund (NDRF). In addition, ₹ 1500 crore is earmarked for mitigation measures to prevent river and coastal erosion for the same period under National Disaster Mitigation Fund (NDMF). For both funds (NDRF and NDMF), State Governments will have to avail resources on a cost-sharing basis. The proposal submitted by the Government of Andhra Pradesh for funding under National Disaster Mitigation Fund (NDMF) is as follows:

o Detailed Project Report (DPR) with an amount of ₹ 323.00 Crore for developing an integrated coastal protection strategy from Kakinada City to Uppada by summarizing and integrating the site-specific works like construction of groyne, sea wall, deflecting wall, Bio- shield etc.

o DPR with an amount of ₹ 200.00 Crore for Control of coastal erosion through structural and non-structural mitigation measures, restoration of ecosystems, 2and enhancement of community resilience in the Visakhapatnam Metropolitan Development Authority (VMRDA) region.

 Coastal Management Information System (CMIS)" under Central Sector Scheme namely "Development of Water Resources Information System" of Ministry of Jal Shakti has been developed considering the importance of data on coastal processes towards coastal protection measures. Coastal data collected through CMIS can be used in planning, design, construction and maintenance of site specific coastal protection structures at vulnerable Coastal stretches. Establishment of three sites under CMIS in the State of Kerala, Tamil Nadu and UT of Puducherry has been completed.

 In addition, Indian National Centre for Ocean Information Services (INCOIS), MoES has prepared the Coastal Vulnerability Index (CVI) maps for the entire coastline of India by using seven parameters such as shoreline change rate, sea-level change rate, coastal elevation, coastal slope, coastal geomorphology, significant wave height and tidal range.

 As informed by the Government of Andhra Pradesh, the State is planning to implement the “Great Green Wall (GGW) of Andhra Pradesh,” envisaged as a 5-kilometre-wide and 1,053-kilometre-long vegetative barrier along its coastline. The proposed initiative is intended to function as a living ecological shield to mitigate the impacts of climate change, including cyclones, storm surges, tsunamis, sea-level rise, and coastal erosion.

The project is proposed to be implemented under the direction of the Department of Environment, Forests, Science & Technology, with the broader objective of enhancing the State’s green cover to 50% by the year 2047.
