India rolls out coastal hazard line mapping

New Delhi, India: The Government of India (GOI) rolled out Stereo Digital Aerial Photography (SDAP) as the first step towards coastal hazard line mapping. The maps will be prepared at 1: 10,000 scale.
To ensure smooth SDAP, the mainland coastline has been divided into eight blocks. They are from the Indo-Pakistan Border to Somnath in Gujarat; Somnath to Ulhas River in Maharashtra; Ulhas River to Sharawati River in Karnataka; Sharawati River to Cape Comorine in Tamil Nadu; Ponniyur River to Krishna River in Andhra Pradesh;Krishna River to Chhattapur in Orissa; and Chhattapur to Indo-Bangla Desh border in West Bengal. 
Through SDAP, flood lines over last 40 years as well as sea level rise impacts will be identified. These data will assess prediction of erosions for next 100 years. This will be undertaken under the World Bank assisted Integrated Coastal Zone Management Project. The estimated cost of this survey is INR 125 crore. 
Recently, the Ministry of Environment & Forests (MoEF), GOI, also released the Shoreline Change Atlas of Orissa. The Atlas contains precise interpretation of shoreline change of the State. The Institute of Ocean Management, Anna University, Chennai had prepared the map. The information will be extremely useful in providing an overview of areas that are likely to be more vulnerable to coastal erosion, identifying areas for development, conservation of coastal and marine resources and to safeguard coastal population from highly eroding and hazard areas.
