Aarhat Multidisciplinary International Education Research Journal (AMIERJ) ( UGC Approved Journal No 48178, 48818 ) ISSN 2278-5655 WETLANDS & ENVIRONMENTAL SUSTAINABILITY: A CASE STUDY Mr. Sunil Kumar Singh A, Assistant Professor, Department of Geography, School of Earth Sciences, Central University of Karnataka. Abstract Wetlands are ecosystems or habitats for specific plants and animals that are saturated with water. The presence or absence of water determines their formation, processes and characteristics. Wetlands are of great importance to man and nature as it purifies water, reduces flood, stores water, prevents soil erosion, supports varied biodiversities etc. Starting about thousands of years in urban areas of the world and typically a few hundred years ago in most other coastal areas, humanity has profoundly impacted, degraded or destroyed many coastal wetlands worldwide by direct physical degradation and pollution. Ironically, reduced coastal wetland increases threat to human safety at the same time, shoreline development exposes populations to coastal hazards such as tsunamis, erosion, flooding, storm waves and surges. This paper tries to evaluate the importance of Wetlands and the present scenario of wetlands and the steps taken by the world community to protect and preserve it. This paper illustrates the present scenario of wetlands by The Case study of Pallikaranai Wetlands of Chennai which presents the best example of the dismal state of wetlands in-spite of numerous efforts taken by academicians, environmentalists and the local community to protect it. Aim 1. To bring out the importance of Wetlands and the need to preserve and protect it. 2. Illustrate the present scenario of Wetlands based on a case study of “Pallikaranai Wetlands Ecosystems in Chennai” and the present scenario of Wetlands around the world. -
Chengalpattu District
DISTRICT DISASTER MANAGEMENT PLAN 2020 CHENGALPATTU DISTRICT District Disaster Management Authority Chengalpattu District, Tamil Nadu DISTRICT DISASTER MANAGEMENT PLAN 2020 DISTRICT DISASTER MANAGEMENT AUTHORITY CHENGALPATTU DISTRICT TAMIL NADU PREFACE Endowed with all the graces of nature’s beauty and abundance, the newly created district of Chengalpattu is a vibrant administrative entity on the North eastern part of the state of Tamil Nadu. In spite of the district’s top-notch status in terms of high educational, human development index and humungous industrial productivity, given its geography, climate and certain other socio-political attributes, the district administration and its people have to co-exist with the probabilities of hazards like floods, cyclone, Tsunami, drought, heat wave, lightning and chemical, biological, radiological and nuclear emergencies. The Disastrous events in the recent past like the Tsunami of 2004, the catastrophic floods of year 2015, the cyclone of year 2016 and most recently the COVID-19 pandemic, will serve as a testament to the district’s vulnerability to such hazards. How the society responds to such vagaries of nature decides the magnitude and intensity of the destruction that may entail hazardous events. It is against this back drop, the roll of the District Disaster Management Authority can be ideally understood. The change in perspective from a relief- based approach to a more holistic disaster management approach has already begun to gain currency among the policy makers due to its substantial success in efficient handling of recent disasters across the globe. The need of the hour, therefore, is a comprehensive disaster management plan which is participative and people-friendly with the component of inter- departmental co-ordination at its crux. -

New Records of Lizards in Tura Peak of West Garo Hills, Meghalaya, India
Journal on New Biological Reports 3(3): 175 – 181 (2014) ISSN 2319 – 1104 (Online) New records of lizards in Tura peak of West Garo Hills, Meghalaya, India Meena A Sangma and Prasanta Kumar Saikia* Animal Ecology & Wildlife Biology Lab, Department of Zoology, Gauhati University, Gauhati, Assam 781014, India (Received on: 04 August, 2014; accepted on: 13 September, 2014) ABSTRACT Intensive survey has been carried out from January 2012 to December 2013 and whatever we have uncovered from Tura peak was photographed and its measurement was taken. The data of Lizards were collected by Active Searching Methods (ASM). Most of the lizard survey was done during the day time as lizards and skinks are seen basking in the sun during the day hours. The identified species of Lizards, geckoes and skinks were photographed and released into their natural habitat. Altogether four species of lizards have been recorded newly in Tura peaks of West Garo Hills of Meghalaya States of North east India. The species were such as Calotes maria and Ptyctolaemus gularis from Agamidae Family and Hemidactylus flaviviridis and Hemidactylus garnooti from Geckonidae Family. All those four species have not been reported from Garo hill in past survey, whereas the species Hemidactylus flaviviridis not been reported from any area of Meghalaya state till date. Key words: New records, Lizards, Tura Peak, measurements, active searching. INTRODUCTION species are so far recorded in the North East India India is incredibly rich in both floral and faunal (Ahmed et al. 2009) and 26 species are represented species but, most of the studies of reptiles has been th in Meghalaya (ZSI,1995).
