Anthropogenic Impacts on Urban Coastal Lagoons in the Western and North-Western Coastal Zones of Sri Lanka
1 2 Anthropogenic Impacts on Urban Coastal Lagoons in the Western and North-western Coastal Zones of Sri Lanka Jinadasa Katupotha Department of Geography, University of Sri Jayewardenepura Gangodawila, Nugegoda 10250, Sri Lanka [email protected] Abstract Six lagoons from Negombo to Puttalam, along the Western and North Western coast of Sri Lanka, show signs of some change due to urbanization-related anthropological activities. Identified activities have direct implications on morphological features of lagoons, elimination of wetlands (mangrove swamps and marshy lands) and pasture lands, land degradation due to encroachment for shrimp farms, shrinking of lagoons, and production of higher nutrient and heavy metal loads, decline in bird and fish populations and degradation of the scenic beauty. As a result, the lagoon ecosystems have suffered to such a degree that numerous faunal and floral species have disappeared or have diminished considerably over the last few years. All these anthropogenic impacts were identified by the author during 1992, 2002, and 2006 as well as in a study on “Lagoons in Sri Lanka” conducted by IWMI between 2011 and 2012. Key words: Anthropogenic Impacts, Urban Coastal Lagoons, Garbage accumulation, Awareness program Introduction The island of Sri Lanka has 82 coastal lagoons that support a variety of plants and animals, and the economy [1]. Anthropogenic impacts, particularly lagoon fishing, human occupation of the land and water contamination have considerably reduced the faunal and floral population to a point that some of them are in danger of extinction. Such danger of extinction has been accelerated in urban lagoons of the western and northwestern coastal zones, e.g. -

HiroshimaHiroshimaGeographicalAssociation Geographical Association Geographical Sciences vol, 43 no.1 pp, 18-36, 1988 Evolution of Coastal Laridforms inthe Western Part of Sri Lanka JINADASA KATUPOTHA* Key Words:evolution of coastal landforms, SriLanka, late Pleistocene, Holocene, landfOmi classMcation Abstract Geomorphic and geologic evidence shows four different stages {Stage I-IV} in the evolution of coastal landforrns on the west coast of Sri Lanka during the Iate Pleistocene and Holocene Epochs. The author assumes that the old ridges in Stage I at Sembulailarna, Kiriyanl(ailiya, Pambala, Wiraliena, Uluambalarna and Kadrana areas have been fonned precedng the Holocene transgression. Low hMs and ridges in the area were coated mainly by wind blown sand, fonowing the lower sea levels during the Late Pleistocene and Earty Holocene Epochs. Radiocarbon datings en the west and seuth coast$ reveal that the sea level remained 1rn or more above the present sea level between 6170± 70 and 535e± 80 yr B. P. During this transgression, the forTner drainage basins were submerged and headland bay beaches were ereated. Many wetlands aiid beach ridges, particularly in Stages ll, III, and IV were gradualy formed owing to rninor oscMations of sea levet after mid-Holocene. Most of these landiorTns haveaclose relationship with main climatic zenes of the country. 1987; Katupotha, 1988) also help to deterrnine their I. Introduction evolution.

Grade 3 Unit 2 Overview Open Ocean Habitats Introduction
G3 U2 OVR GRADE 3 UNIT 2 OVERVIEW Open Ocean Habitats Introduction The open ocean has always played a vital role in the culture, subsistence, and economic well-being of Hawai‘i’s inhabitants. The Hawaiian Islands lie in the Pacifi c Ocean, a body of water covering more than one-third of the Earth’s surface. In the following four lessons, students learn about open ocean habitats, from the ocean’s lighter surface to the darker bottom fl oor thousands of feet below the surface. Although organisms are scarce in the deep sea, there is a large diversity of organisms in addition to bottom fi sh such as polycheate worms, crustaceans, and bivalve mollusks. They come to realize that few things in the open ocean have adapted to cope with the increased pressure from the weight of the water column at that depth, in complete darkness and frigid temperatures. Students fi nd out, through instruction, presentations, and website research, that the vast open ocean is divided into zones. The pelagic zone consists of the open ocean habitat that begins at the edge of the continental shelf and extends from the surface to the ocean bottom. This zone is further sub-divided into the photic (sunlight) and disphotic (twilight) zones where most ocean organisms live. Below these two sub-zones is the aphotic (darkness) zone. In this unit, students learn about each of the ocean zones, and identify and note animals living in each zone. They also research and keep records of the evolutionary physical features and functions that animals they study have acquired to survive in harsh open ocean habitats. -

Galle Harbour Maritime Archaeological Impact Assessment Report for Sri Lankan Department of Archaeology
Galle Harbour Maritime Archaeological Impact Assessment Report for Sri Lankan Department of Archaeology Ross Anderson, Jeremy Green and Corioli Souter Western Australian Museum, Department of Maritime Archaeology Report–Department of Maritime Archaeology, Western Australian Museum, No. 235. 2007 Background Following discussions between the Sri Lankan Department of Archaeology (SLDA) and Department of Maritime Archaeology, Western Australian Museum (WAM), WAM was engaged as a consultant to undertake a maritime archaeological survey of Galle Harbour as part of an Archaeological Impact Assessment (AIA) process. The scope of the consultancy was to carry out a maritime archaeological survey, and provide a report to the SLDA outlining the impact of the proposed Galle port development on the underwater cultural heritage of Galle Harbour. The survey took place between 14 November and 2 December 2007. WAM has been involved in maritime archaeological investigations in Galle Harbour since 1992. Previous work includes: remote sensing surveys, site inspections and excavation of shipwrecks. Remote sensing and diving search projects undertaken in 1992, 1993 and 1996 resulted in the location of a range of significant maritime heritage sites in the harbour including Arab-Indian stone anchors, the VOC wrecks of the Avondster (1659) and Hercules (1661) and 19th century iron steamship wrecks. Due to advances since 1997 in position-fixing and remote sensing techniques, it was necessary to resurvey the proposed port development area to accurately position and identify possible sites to be impacted by the development. Existing GPS positions were only accurate to 200 m as a result of GPS Selective Availability (decommissioned in 2000). As part of the contractual agreement between WAM and the Sri Lankan Department of Archaeology, this report is to be submitted to the Sri Lankan Department of Archaeology by 17 December 2007. -

Sovereignty Vs. Trans-Boundary Environmental Harm: the Evolving International Law Obligations and the Sethusamuduram Ship Channel Project
Sovereignty vs. trans-boundary environmental harm: The evolving International law obligations and the Sethusamuduram Ship Channel Project Chinthaka Mendis - United Nations / Nippon Foundation Fellow 2006 1 Acknowledgements The present paper address a topic, which has recently experienced an explosion of new developments and gained enormous importance to small developing nations like Sri Lanka. It has enabled States that may be affected by environmentally degrading activities of other States to take safeguard actions in a successful manner. Furthermore this evolving new law of international responsibility attempts to strike a careful balance between international environmental protection and the principle of territorial sovereignty. This is a very interesting and thought provoking area of research and to my humble delight my supervisors Professor Betsy Baker of Harvard Law School and Dr. Francois Bailet of UN Division for Ocean Affairs and the Law of the Sea responded with great enthusiasm. I sincerely say that I am deeply indebted to both of them for their valuable review of my work and the great support extended to me in performing my task. In fact my interesting tenure at the Harvard Law School and DOALOS, as a United Nations/Nippon Fellow allowed me to refine my knowledge of international law and become better acquainted with this evolving international system. Thus, the Division for Ocean Affairs and the Law of the Sea, Office of Legal Affairs, United Nations and the Nippon Foundation of Japan richly deserve my most appreciative thanks for their cooperation in the establishment of this rewarding fellowship programme.
