Introduction India has a peculiar climate diversity under which nearly 80 percent of the annual precipitation is limited to a brief monsoon period generally less than 100 days. Even though the country receives an annual rainfall of 1170 mm on an average, the complex system of monsoon winds and the peculiar orientation of mountains give rise to some excessively low rainfall regions and well-diversified pockets of water scarcity in one part of the country and simultaneously the other parts of t...
Introduction Mangrove forests are among the world’s most productive ecosystem. They enrich coastal waters, yield commercial forest products, protect coastlines, and support coastal fisheries. It thrives on tropical climate and on coastal waters in Asia, Africa and South America. They thrive on the harshest environments, usually waters with high salinity, extreme tides, strong winds, high temperatures, muddy and anaerobic soils.1 As of year 2011, it is estimated that the remaining ma...

Introduction Morphometric studies are first attempted by Horton, Strahler, Smith, Schumm, and Miller1-5. Parallel work of basin morphometry has been carried out by Abrahams, Langbein, Leopold, and Maddock6-8. The morphometric analysis is done with linear, aerial, relief aspect, the slope, and a gradient of a channel by many researchers9,10. Basin morphometry gives the signs of an influence on river hydrology and river channel. Similar work is done by Sapkale on Tarali river with an approach o...
Introduction The earth resources are key component in the development of a nation as well as of a region. The update information of the landscape is of great significance in the management and monitoring of an environment. LU/LC classification is one of the prime prerequisites for analyzing the information of the existing earth resources and changes occurring on the landscape pattern of an area through time. Land cover data refers to the area of a region covered under natural resources viz. f...
Introduction Identity is seen as a fundamental need that encompasses all aspects of human life 1 in an age of increased loss of identity, as our lives and places lose their distinctiveness. In contemporary times, the need for stability is crucial for humans, who require development of emotional bonds with places. Therefore, people’s relations with places have been explored using a wide array of psychological constructs such as place identity2, place attachment 3,4, and sense of plac...
