More than 3000 acres of the wetlands have been lost to: X BPCL and HPCL’s oil storage terminals X Port infrastructure for Kamarajar Port Ltd and L&T Shipbuilding X NTECL power plant and coal ash dump X Flyash spilled into the river from TANGEDCO’s leaking pipelines That is why Kosasthalaiyar’s floodwaters flooded North Chennai so badly in 2015. Imminent Threats: X Kamarajar Port intends to expand over an additional 600 acres X TANGEDCO and TANTRANSCO is encroaching into the wetlands and obliterating mangroves to construct coal conveyors and transmission towers X TNRDC is expanding its road by eating into the wetlands XAdani Ports & SEZ’s subsidiary Marine Infrastructure Development Private Ltd plans to construct a mega port and SEZ in the region O 2000 acres of new land will be created by dumping dredged sea sand and river sand into the sea. This will smother the fishing grounds which are a rich habitat for prawns and crabs O An additional 2000 acres will be reclaimed by dumping sand, earth and debris on salt marshes, salt pans, irrigation tanks, ponds, water channels, freshwater springs and other water-related Poromboke areas O The Kattupalli dunes will be levelled and paved for port facilities. This will cause groundwater aquifers to turn saline. X About 6 km of beach will be privatised, paved and blocked off. The Karungali river mouth will be blocked intensify the risk of disastrous flooding in Thiruvallur and coastal Andhra Pradesh. X Erosion triggered by the breakwater will breach the thin Kattupalli barrier island and merge Pulicat lagoon with the Bay. X The fishing villages on the barrier island – Korakuppam, Vairavankuppam, Arangankuppam, Lighthouse and Koonankuppam – will be lost to the sea due to sea erosion triggered by the port. X Villages like Senganimedu, Urnambedu to the west will lose grazing lands and their livestock- dependent economy. X The encroachments will place 10 lakh people in the assembly constituencies of Thiruvottiyur, R.K. Nagar, Madhavaram, Ponneri and Gummidipoondi at a heightened risk of disastrous flooding and water stress. ADANI PORT - Key Information Investment: A sum of Rs. 53,031 crores is mentioned as the total capital cost for the proposed Revised Master Plan development Cargo handling 24.65 MTPA is current Total Handling Capacity at the Port. Is proposed to be increa- capacity: sed to 320 MTPA, which is a third of the combined capacity of all ports in India. Land use: For the expansion of the port, an additional area of 2339.35 Ha is proposed and out of which 796.15 Ha (approx.) area will be reclaimed from the sea. Breakwater length: The length of two new proposed breakwater is about 12.10 km.

  • The Pulicat Lake, Adjoining the Bay of Bengal Is a Shallow Water Body, Bordering the East Coast of India and Located 40 Km North of Chennai
    ENVIRONMENTAL GEOCHEMISTRY OF THE PULICAT LAKE, SOUTH INDIA PURANIK GAYATRI RANGANATH JUNE-2000 ABSTRACT The Pulicat lake, adjoining the Bay of Bengal is a shallow water body, bordering the east coast of India and located 40 km north of Chennai. The lake is one of the largest salt-water lake in India that supports a wide range of socioeconomic and cultural activities. The primary aim of this study is to understand the biogeochemical processes of the Pulicat lake ecosystem in order to preserve the ecological and environmental characteristics of this fragile ecosystem. Seasonal samples of water, bed, suspended and core sediments were collected over a one-year period in three zones (southern-channel, central and northern regions) of the Pulicat lake. The lake receives fresh water discharge only during monsoon, from two seasonal rivers, the Arani discharging into the southern region of the lake (zone I) and the Kalangi discharging into the northwestern region of the lake (zone III). The Buckingham canal, running parallel to the coastline discharges sewage contaminated water and industrial effluents into the Pulicat lake. Due to the limited freshwater supply and tidal action, the mouth of the lake gets silted up and closed during the dry season. Understanding the spatial and seasonal variations in the water chemistry was one of the primary aspects of this study. The chemical composition of the surface water indicates a strong influence by seawater during the summer and diluted by river water during the monsoon season. The results obtained indicate that the dominant cations and anions of the surface water are in the order of Cl>Na>S04>K>Mg>HC03>Ca.

Chennai, the capital city of Tamil Nadu is located in the South East of India and lies at a mere 6.7m above mean sea level. Chennai is in a vulnerable location due to storm surges as well as tropical cyclones that bring about heavy rains and yearly floods. The 2004 Tsunami greatly affected the coast, and rapid urbanization, accompanied by the reduction in the natural drain capacity of the ground caused by encroachments on marshes, wetlands and other ecologically sensitive and permeable areas has contributed to repeat flood events in the city. Channelized rivers and canals contaminated through the presence of informal settlements and garbage has exasperated the situation. Natural and man-made water infrastructures that include, monsoon water harvesting and storage systems such as the Temple tanks and reservoirs have been polluted, and have fallen into disuse.

    322 Indian Journal of Science and Technology Vol. 4 issue 3 (March 2011) ISSN: 0974- 6846 Need of coastal resource management in Pulicat Lake–challenges ahead N. Thirunavukkarasu, S. Gokulakrishnan, P. V. R. Premjothi and R. Moses Inbaraj Dept. of Marine Studies and Coastal Resource Management, Madras Christian College, Tambaram, Chennai–59, India [email protected] Abstract Coastal zones are currently experiencing intense and sustained environmental pressures from a range of driving forces. Responsible agencies around the globe are seeking ways of better managing the causes and consequences of the environmental change process in coastal areas. The demands on the environment are raising serious concerns from environmentalists, stakeholders, coastal communities and researchers. Pulicat Lake is the second largest lagoon in India has rich natural but at the same time very fragile ecosystem. This lagoon provides nursery and breeding grounds for many species of marine fauna and supports commercial fishing too. This article discusses the current status of the Pulicat Lake biodiversity, the ecological crisis faced by the lake due to lake-mouth closure issues, siltation, shrinkage of the lake, pollution, over fishing, degradation and destruction of natural habitats in the environment. Further it focus on fishermen community socio-economic perspectives of their development towards livelihoods, social organization, literacy, fishing pattern, marketing outlet, income and involvement by NGO’s etc. The healthier lake needs integrated policy approaches, which involve scientific disciplines to address the complexity of the interaction between the social and natural systems in the coastal and marine environment. Keywords: Pulicat Lake, fragile ecosystem, siltation, literacy, fishing pattern. Introduction there is a need to conserve the ecosystem with potential Pulicat Lake is the second largest brackish water lake, biodiversity resources as well as fishermen community lying partly in Tamil Nadu and Andhra Pradesh.

    ISSN: 0974-2115 www.jchps.com Journal of Chemical and Pharmaceutical Sciences Groundwater Suitability for Irrigation in Pulicat Using GIS D.Sivakumar1, P Abraham Daniel Raj2, E Arivoli2, M Hemalatha2 1Department of Civil Engineering, Vel Tech High Tech Dr.RangarajanDr.Sakunthala Engineering College, Avadi, Chennai 600062, Tamil Nadu, India 2M.E Integrated Water Resources Management, Centre for Water Resources, Anna University, Chennai 600025, Tamil Nadu, India *Corresponding author: E.Mail:[email protected] ABSTRACT In India, 75 % of population depend on agriculture for their earnings and survival. Rainfall in India is erratic, which received from the month of June to September. Irrigated Agriculture does not depend only on surface water available. It can be sustained by combined usage of surface water and groundwater available. In order to ascertain the quality of groundwater in Pulicat region for irrigation, the various physic-chemical parameters like pH, total dissolved solids, total hardness, calcium, magnesium, sodium, potassium, carbonate, and bicarbonate were selected and the selected irrigation indices are sodium adsorption ratio, soluble sodium percentage, residual sodium bicarbonate, magnesium adsorption ratio, and Kelly’s ratio. The obtained results were depicted using GIS tool to suggest the better place for farming. The results of irrigation indices have proved that the water is unfit for cultivation, but, some salt tolerant crops may be grown in a selected study area. Keywords: Ground water, Irrigation water quality indices, Physico-chemical parameters. 1. INTRODUCTION Watering is essential for cultivating of all types of crops. If rainfall is not adequate, then agriculture depends on only rainfall. Rainfall in India is also erratic and people receive this rainfall only between the month of June and September.
