World Bank Document Project Implementation Agency Public Disclosure Authorized Emergency Tsunami Reconstruction Project Government of Puducherry Environmental Impact Assessment Study for Reconstruction and Modernization of Puduchery Fishing Harbour Public Disclosure Authorized April 2011 Public Disclosure Authorized WAPCOS Limited Public Disclosure Authorized EXECUTIVE SUMMARY 1. GENERAL The Puduchery fishing harbour is constructed on Ariyankuppam river mouth at Thengaithittu in Puducherry. At present 115 mechanized boats are operated from this fishing harbour. The other facilities available in this fishing harbour are 2 Nos. of Auction hall, Work shed, Diesel (bunk) outlet, Vehicle parking shed, Fishing boat repair yard, Fishing Harbour Management Society Office, One power room with 440 volts capacity receiving 315 KW power from transformer, Overhead tank capacity of 80,000 litres. Puducherry fisheries department proposes the reconstruction and modernization works in the existing fishing harbour at Puduchery to augument the above mentioned facilities for additional fish catch. The present document outlines the Executive Summary of the EIA study of Reconstruction and Modernization of Puducherry fishing harbor. 2. PROJECT DESCRIPTION The proposed of Reconstruction and Modernization of Puducherry fishing harbor envisages the following facilities: Extension of Quay and providing appropriate fender on the quay. Modernisation of sloping yard Marine Mechanized Workshop Boat making and repairing yard Fish Processing Unit Ice Plant Treatment for discharge of effluent sullage 2.1 EXTENSION OF QUAY Puducherry Fishing Harbour has 119 wooden mechanized boats and 83 are FRB boats with inboard Engine. The total length of quay required for Mechanised and FRB boats shall be 540 m. A wharf of 330 m length is already available, and it is proposed to extend the wharf by another 200 m to accommodate additional number of boats. It is proposed to have the lower level for anchoring the FRP boats and to dredge upto -2.5m level on the basin side for facilitating the berthing of vessels without any hardship. 2.2 MODERNIZATION OF SLOPING YARD There is no proper rail arrangement and cradle system to receive the boats and there is no proper hauling system to beach the boat for repairing and the fisherman communities are finding great difficulty for beaching their vessel for repair. Following works are proposed for the modernization of sloping yard: Construction of cofferdam in front of the sloping hard to rectify the damage if any. The disturbed portion of the existing sloping hard floor is proposed for improvement. Providing CR100 Rail of 2.5 m at 3 m apart in sloping hard area, transfer bay area for the movement of transfer cradle and also in the boat making and repair yard. Providing winch room with winch of suitable capacity. Fabrication of sloping cradle, Boat trolley and Transfer cradle. There is no proper workshop for the repair of engines, propeller etc., and the fisherman find it difficult to repair them. Therefore, it is proposed to have one workshop at the harbour. 2.3 BOAT MAKING AND REPAIR YARD The proposed boat making and Repair Yard is placed at northern side of the sloping yard. It consists of 3 Bays on each side and each bay is provided with CR100 Rail arrangements. There is no boat making and repair yard at present in Puducherry and the fishermen are finding it difficult to build or repair the Boat. The fisherman has to go to Cuddalore for utilising the boat making and repair yard facilities. In this Boat making and Repair yard, 6 Nos. of Boats can be repaired or build at a time. 2.4 ICE PLANT WAPCOS Centre for Environment 1 As per CMFRI data the total fish catch at Puducherry is 26 tonne per day. Approximately 50% of total fish catch is considered for iceing, hence the total quantity of ice required at Puducherry harbor is estimated to be 53 tonnes. The ice plants available in Puducherry do not fulfill the ice requirement at Puducherry. Hence, it is proposed to provide a ice plant with a capacity of 50 tonnes per day. 2.5 FISH PROCESSING UNIT The fish process consists of mainly processing unit, freezing unit and chilled storage unit. It is proposed to have a fish processing unit of 6T capacity initially which will be expanded to 12T capacity at ultimate stage (year 2040) to process, freeze and preserve the low value fishes and to supply the same in the local market at higher cost. 2.6 NET MENDING SHED At present there is no proper net mending shed to mend their nets and the fishermen are using the existing auction halls for this purpose and therefore it is proposed to construct the same. 2.7 TREATMENT OF SULLAGE On the commencement of full-fledged commercial activity in modernised Puducherry fishing harbour, it is expected that around 750 fishermen (150 x 5) and around 250 outsiders may use the harbour. The average fish catch per day is 26 Tonnes and the total sullage expected to be generated in the fishing harbour is estimated as 40,000 litres/day. In addition, around 10,000 litres/day is expected to be generated in the pre-processing unit. Hence the total quantity of sullage likely to be generated in the Puducherry fishing harbour shall be 50,000 litres. It is proposed to provide a comprehensive sullage collection and treatment system . 2.8 DREDGING As per the Feasibility Report, during the Pre-stake holder’s meeting conducted on 24.04.2009, it was unanimously demanded to dredge the mouth as well as the fishing harbour area for navigation and berthing of vessels. A detailed Bathymetry survey to ascertain the depth available in front of the wharf and along the approach channel in the river was carried out. From the Bathymetry chart, it is seen that the depth available in front of the wharf and upto the tip of the break water is less than required. The total quantity of dredging envisaged is 272764 m3. The project layout map as superimposed on HTL/LTL map is enclosed as Figure-1. The Cost Estimate has been prepared and the total cost for the Puducherry Fishing Harbour has been estimated as Rs.1907.70 lakhs. 4. ENVIRONMENTAL BASELINE STATUS The Study Area considered for the EIA study has been considered as the area within radius of 10 km considering the proposed project site at the centre. As a part of the EIA study, the baseline status has been ascertained for various aspects and the same is summarized in the following sections: 4.1 METEOROLOGY In the project area the average annual rainfall is 1245 mm. Majority of rainfall is received in the period from October to December. In the project area, the temperature starts increasing from February end and it reaches up to 37 oC. The average maximum and minimum temperatures during the summer season are 43 oC and 27 oC respectively. 4.2 AMBIENT AIR QUALITY The ambient air quality monitoring was carried out with a frequency of two samples per week at three locations in August / September, 2010. The parameters monitored as a part of the study are listed as below: • PM 10 • PM 2.5 • Sulphur dioxide (SO 2) WAPCOS Centre for Environment 2 • Oxides of Nitrogen (NOx). 3 The PM 2.5 concentration varies from 21.46 to 31.68 µg/m at various stations Values of PM 10 ranged from 23.33 to 35.57 µg/m 3, which is below the prescribed limits of 60 µg/m 3 and 100 3 µg/m respectively. The concentration of SO 2 at various stations ranged from 5.21 to 8.59 3 3 µg/m , which is below the prescribed limits of 80 µg/m . Similarly NO X concentration was below detectable limits. 4.3 NOISE ENVIRONMENT Baseline noise levels were recorded at 3 locations in the study area and equivalent noise level were calculated. The day time noise level ranged from a minimum of 29 dB(A) to a maximum of 40 dB(A). The night time noise level ranged from a minimum of 26 dB(A) to a maximum of 33 dB(A), which area well below the permissible limit. 4.4 LANDUSE PATTERN The landuse pattern of the study area has also been studied using satellite data. The major portion of study area is occupied by water bodies (51.78%). Area under vegetation and agriculture accounts for about 17.29 % and 19.56 % of the total study area respectively. The settlements and barren area are about 3.62%, and 6.22 % respectively. 4.5 MARINE WATER QUALITY The temperature of the surface water samples ranged from 24°C to 26°C. pH value also did not exhibit insignificant variation and was in the range of 8.0 – 8.2. There is no fresh water influence was recorded during the time of collection and thus the salinity of surface water samples varied from 29 to 31 ppt. The DO values recorded in the four stations ranged from 4.20 mg/l to 4.60 mg/l. Biochemical Oxygen Demand varied from 1.04 to 1.35 mg/l. The phosphate and nitrates concentrations varied between 0.329 to .538 µmol/l and 1.071 to 1.115 µmol/l respectively. Major Elements and Trace Metals The concentration of cadmium in the water samples varied from 0.19 to 0.31 µg/l. The concentration of Zinc in the study areas varied between12.0 to 13.80 µg/l. The estimated concentrations of lead ranged from 3 to 4.2 µg/l. The mercury level varied from 12 mg/l to 13 mg/l. 4.6 Sediment Quality The pH of sediments at various samples ranged from 8.1 to 8.2.

Mail. ID: [email protected] Mobile No: 09444891589 Arikamedu and Rome –Ancient Trade contact The place which is 5 kmsaway from Puduchery is known as,” Arikamedu”. It is located on the banks of the river Ariyankuppam near Kakaiyanthoppu, enrouteAriyankuppam and Virampattinam, which is 20 feet in height in the form of a mound. Today this placeexists as clam and humble garden area. The very same place was once flourished as a multi – national port city. During ancient period, this place was inhabited by the people who were hailed from different countries and they spoke many different languages. On the basis of trade and commerce they mingled with one another. In the beginning years of the 18th century very few Christian Fathers lived in Puducherry. They instituted missionaries at Arikamedu and did their religious services. They never knew about the ancient podukal’s history or specialty. Later, in 1769 A D, Le Gentil, a French astronomical expert came to Puducherry for his research. He personally visited the Veerampattinam and Arikamedu areas. In his travel accounts he mentions about an Arukansilai(Buddha Statue) which was discovered by him. By this finding the place of Arikamedu won 1st and became noticeable by the historians(researchers). Later in the early years of the 20th century 1937 AD, JoyveaeDubraille, a physics professor, Puduvai-French college visited Arikamedu many times to see the ruins of the Christian Misisionary.

  • Shoreline Change Studies Due to Construction of Breakwaters at Ariyankuppam River Mouth in Puducherry – a Union Territory of India, South India
    ISSN (Print) : 0974-6846 Indian Journal of Science and Technology, Vol 9(45), DOI: 10.17485/ijst/2016/v9i45/101933, December 2016 ISSN (Online) : 0974-5645 Shoreline Change Studies Due to Construction of Breakwaters at Ariyankuppam River Mouth in Puducherry – a Union Territory of India, South India P. Mohamed Rajab* and K. Thiruvenkatasamy Department of Harbor and Ocean Engineering, AMET University, Plot No.135, East Coast Road, Kanathur, Chennai - 603112, Tamil Nadu, India; [email protected], [email protected] Abstract Objectives: In the present investigation, the shoreline change studies were carried out along the Pudhuchery coast using an online model such as DHI-LITPACK modules suite. Methods/Statistical Analysis: The study area covers 5 km on the southern side and 10 km on the northern side of the Ariyankuppam river port breakwaters. One year measured data off Puducherry coast at 15 m water depth was used for the estimation of littoral drift and to predict the shoreline changes along the Puducherry coast. The predicted shoreline changes using one-line model show good agreement with historical shoreline changes along the Puducherry coast. Findings: The shoreline change studies with existing coastal structures shows that, on the seawall northern end, the shoreline experiences erosion up to 10m, 20m, 35m, 45m, 55m and 60m after a period of 1, 2, 5, 10, 15 and 20 years respectively and the erosion is noticed for a distance of 1400m along the coast. The shoreline changes study with sand bypassing the net annual littoral sediment of 0.13 x106 m3 from the southern side of the south port breakwater to the northern side of the north breakwater show that shoreline erosion is limited to 20 m and extends 500 m along the coast on the northern end of the seawall.

Hazards can be single, sequential or combined in their origin and effects. Accordingly, Hazard Analysis entails the identification, study and monitoring of a hazard to determine its potential, origin and characteristics. A fine line separates environmental hazards and environmental resources, as between water out of control (flood hazard) and water under control (reservoir resources). The 18 Disaster Management atmosphere is considered ‘benign’ when it produces holiday sunshine but ‘hostile’ when it produces damaging ‘loo’ (Smith, 1996). A disaster is a result of natural or man-made causes that leads to sudden disruption of normal life, causing severe damage to life and property to an extent that available social and economic protection mechanisms are inadequate to cope.

    International Journal of Science, Environment and Technology, Vol. 1, No 5, 2012, 363 - 376 STUDIES ON THE POLLUTION LEVELS IN ARIYANKUPPAM BACKWATER, PUDUCHERRY REGION G. VIJAYAKUMAR 1, M.A. SIVASANKARAN 2 and V. MURUGAIYAN 3 Associate Professor 1,3 , Professor 2, Department of Civil Engineering, Pondicherry Engineering College, Pondicherry – 605014 E-mail: [email protected] Abstract: A systematic investigation in the pollution level at Ariyankuppam backwater from March 2011 to February 2012 was carried out. The untreated domestic wastes from various parts of the Ariyankuppam town are directly discharged into the river which leads to an increased level of pollution. The present studies emphasis on the magnitude of pollution by monitoring key water quality parameters such as dissolved oxygen, temperature, pH, salinity, B.O.D, C.O.D and Chlorophyll content. Monthly water samples were collected from three different sampling stations, which give the information about the rate of pollution and its influence on the aquatic environment .Water temperature recorded for the entire study period showed a wide variation and ranged between 24° C to 29.5° C. The range of salinity varied between 260 to 3055 ppm. The pH level shows more alkaline during the month of December due to rain and less alkaline during the month of March. Some of the characteristics like DO, BOD, and nutrient loading are causes for eutrophication process in this backwater, found to be eutrophic throughout the year. 1.0 Introduction The Union territory of Puducherry is located on the eastern coastal region of Peninsular India. Initially agriculture and fishing formed the major source of income for this region.

  • A Statistical Study on Women's Perception on Violence Against
    International Journal of Criminology and Sociological Theory, Vol. 6, No.3, June 2013, 61-67 A Statistical Study on Women’s Perception on Violence against Women in Puducherry _________________________________________________________________________ Kiruthika Chandrasekaran Abstract Violence against women is a crucial topic of discussion in all the countries in the world. Violence against women is classified mainly as physical, sexual and psychological violence. In India, in spite of government’s policy to overcome this problem, violence against women is predominant. The National Crime Records Bureau (NCRB) report on violence against women in Puducherry shows that very few incidents are actually reported. The main focus of present study is to know the opinion on violence against women and remedial measures from the women above 18 years of age in Puducherry. Socio-economic characteristics of the respondents are also reported in this paper. The main factors influencing the occurrence of violence against women are also explored using statistical techniques. Introduction The United Nations Declaration on the elimination of Violence Against Women adopted by the UN General Assembly in 1993 define “Violence Against Women” as “Any act of gender-based violence that results in, or likely to result in physical, sexual or mental harm or suffering to women, including threats to such acts, coercion or arbitrary deprivation of liberty, whether occurring in public or private life”. Violence against women continues to be a human rights issue in many countries in spite of the fact that numerous efforts are taken to eliminate it at the national and international levels. In spite of the prosperity, globalization, education and empowerment of women, we have failed to eliminate violence against women.
