K. Puram, New Delhi-110066 FOREWORD Salinity is a significant challenge and poses risks to sustainable development of Coastal regions of India. If left unmanaged, salinity has serious implications for water quality, biodiversity, agricultural productivity, supply of water for critical human needs and industry and the longevity of infrastructure. The Coastal Salinity has become a persistent problem due to ingress of the sea water inland. This is the most significant environmental and economical challenge and needs immediate attention. The coastal areas are more susceptible as these are pockets of development in the country. Most of the trade happens in the coastal areas which lead to extensive migration in the coastal areas. This led to the depletion of the coastal fresh water resources. Digging more and more deeper wells has led to the ingress of sea water into the fresh water aquifers turning them saline. The rainfall patterns, water resources, geology/hydro-geology vary from region to region along the coastal belt.

ANANDAN MINISTER FOR FORESTS © GOVERNMENT OF TAMIL NADU 2014 DEMAND No.54 POLICY NOTE 2014-2015 FOREST DEPARTMENT INTRODUCTION "kâÚU« k©Q« kiyÍ« mâãH‰ fhL« cilaJ mu©" - ÂU¡FwŸ (742) "A fort is that which owns fount of waters crystal clear, an open space, a hill, and shade of beauteous forest near." - Thirukkural (742) The ancient Tamil poets have emphasized the importance of dense forests, clean water and fertile soil in providing ecological security to the mankind. Forests are a complex eco-system which play a dual role of a renewable resource and also as a vital support base for safeguarding the overall environment and ecological balance. It is forest cover that has preserved the soil and its heavy humus that has acted as a porous reservoir to 1 retain water and is gradually releasing it in a sustained flow over a period of time. Trees draw water from the earth crust and release it to the atmosphere by process of transpiration as a part of water cycle. Trees also purify the air by releasing oxygen into the atmosphere after consuming carbon-di-oxide during photosynthesis. The survival and well-being of any nation depends on sustainable social and economic progress, which satisfies the needs of the present generation without compromising the interest of future generation. Spiraling population and increasing industrialization have posed a serious challenge to the preservation of our terrestrial and aquatic ecosystems. Overexploitation of our resources due to rapid population growth has lead to degradation of forests and denudation of agricultural lands.

Research Scholar, Department of Biochemistry, Mohamed Sathak College of Arts & Science, Sholinganallur, Chennai – 600119, Tamil nadu, India 2. Assistant professor, Department of Biochemistry, Mohamed Sathak College of Arts & Science, Sholinganallur, Chennai – 600119, Tamil nadu, India. Corresponding Author: S.Thangamalathi1 Abstract: The present studies were made on the analysis of heavy metals in relation to physico-chemical parameters with respect to pollution status of lake water from various regions (Ambattur lake, Chembarambakkam lake, Korattur lake, Porur lake, Pulicat lake, Puzhal lake and Retteri lake) in Chennai, Tamilnadu, during April 2017 to November 2017, Tamil Nadu, India. Surface water samples were collected from seven different regions at monsoon, post monsoon, summer and pre-monsoon seasons. The samples were analyzed for physico – chemical parameters include colour, odour, pH, EC, TH, Turbidity, TDS, BOD, COD, DO, F, Ca, Mg, Mn, Cl, Fe and SO₄. In the present study results showed that higher level of heavy metal concentration in the water has a high potential to concentrate heavy metals like lithium, Cd, Pb, As, Al, Ni and Cr though the observed concentrations are above the permissible limits except two metals (Zn and Al) are within the permissible limits. Based on these results there is serious heavy metal pollution in these lake.

Abstract Species richness, and seasonal variation of birds were studied in Pondicherry University campus between February 2014 and February 2015. The data from the fall migration season of 2014 were compared with data from 2004 to understand the decadal changes in the bird diversity of the campus. A total of 96 species were recorded during the course of the study, of which 23 are new records for the university campus. Species richness varied considerably across the sampling duration, was highest during the fall migration season (78 species), and lowest during breeding season (54 species). Comparison of data, to understand the decadal changes in avifauna, revealed that 20 species, which were reported earlier from the campus, were not recorded during the present study.

  • Assessment on Coral Reef and Seagrass Meadows Within the 10Km Radius from the Proposed Groynes Site in Keelavaippar Coast, Gulf of Mannar
    Assessment on coral reef and seagrass meadows within the 10km radius from the proposed groynes site in Keelavaippar coast, Gulf of Mannar 1. BACKGROUND The Gulf of Mannar (GoM) located in the southeast coast of India extends from Rameswaram Island in the north to Kanyakumari in the south and is important coastal area. GoM has been declared as Marine Biosphere Reserve by Government of India in 1989, covering 10,500 km2. Corals and coral reefs of Gulf of Mannar form an important ecosystem, which support a variety of commercial and ornamental faunal and floral species including fishery resources. The islands occur at an average distance of 8-10 km from the mainland. The 21 islands and the surrounding shallow water area covering 560 km2 were declared as Marine National Park. Along with corals, luxuriant and patch seagrass meadows in GoM provide high biodiversity. The Tuticorin group of islands is located at the southern tip of the Gulf of Mannar Marine National Park which consists of four islands. Among them, two coral reef islands which occur closer to the proposed groynes location. Proposed groynessites are located in Keelavipar coast and the project site comes within the Marine biosphere Reserve and about 2 Km away from the Marine National Park boundary. Tamil nadu fisheries department proposed to set up three groynes (Groynes - 1, Groynes - 2 and Groynes - 3) in Keelavaipar coast within 1 km proximity to the marine zone and these sites occurring in shore distance of 1 Km. Groynes - 1 would be covering a distance of 800 meter; Groynes - 2 covers a distance of 500 meter; and Groynes - 3 which is covering a distance of 100 meter towards marine zone.
