Our Precarious Earth and Its Biosphere
I. The Environment 1 The Earth’s Biosphere: Our Life Support System Our common shared biosphere is our planet’s life support system, capturing light via photosynthesis, conserving energy and matter, and obeying the basic laws of physics and thermodynamics. These laws are fundamental, governing all occurrences in the universe. All biological systems must abide by them. We must function within their confines. In spite of the universality of these laws, problems arise because of humans and their activities. There are simply too many of us for our planet. We are consuming too many irreplaceable resources and causing long-lasting planetary damage. This last problem is tremendously enhanced by human greed and a disregard by many for the biosphere. When our numbers were much smaller, our impact could be absorbed. This is not so today. Because we operate within the confines of the universal laws, we cannot continue to squander resources as we have in the past. Consider the following question: How much damage is caused to the natural environment in order to make a profit from the sale of a consumable item? Consider that many of the consumables produced are dispensable and often of minimal value. Realize that valuable resources must be used for their production. Moreover, these products ultimately become waste that must be disposed of, often in a manner that harms the environment. Why allow the continuation of activities that damage our common life support system? We already know that much of this damage cannot be repaired without a human population decrease. Why allow an increase in our population, recognizing that the consequence will be immense human suffering? Why allow resource consumption, pollution and global warming when we know that their continuance will prevent us from solving global problems and meeting the immense challenges that lie before us? We behave as though we have no regard for future generations. -
Lesson 6.Pmd
Natural Ecosystem MODULE - 2 Ecological Concepts and Issues 6 Notes NATURAL ECOSYSTEM Whenever you travel long distance you come across changing patterns of landscape. As you move out from your city or village, you see croplands, grasslands, or in some areas a forests, desert or a mountainous region. These distinct landscapes are differentiated primarily due to the type of vegetation in these areas. Physical and geographical factors such as rainfall, temperature, elevation, soil type etc. determine the nature of the vegetation. In this lesson you will learn about the natural ecosystems with their varied vegetation and associated wildlife. OBJECTIVES After completing this lesson, you will be able to: • list the various natural ecosystems; • describe the various terrestrial ecosystems; • describe the various aquatic ecosystems (fresh water, marine and estuarine); • recognize ecotones, their significance and the edge effect. • list the major Indian ecosystems; • list the threatened ecosystems-mangrove, wetlands, coastal ecosystems and islands; • explain the need and methods of conservation of natural ecosystems. 6.1 WHAT ARE NATURAL ECOSYSTEMS A natural ecosystem is an assemblage of plants and animals which functions as a unit and is capable of maintaining its identity such as forest, grassland, an estuary, human intervention is an example of a natural ecosystem. A natural ecosystem is totally dependent on solar energy. There are two main categories of ecosystems. 95 MODULE - 2 Environmental Science Senior Secondary Course Ecological Concepts and Issues (1) Terrestrial ecosystem: Ecosystems found on land e.g. forest, grasslands, deserts, tundra. (2) Aquatic ecosystem: Plants and animal community found in water bodies. These can be further classified into two sub groups. -
Smart Border Management: Indian Coastal and Maritime Security
Contents Foreword p2/ Preface p3/ Overview p4/ Current initiatives p12/ Challenges and way forward p25/ International examples p28/Sources p32/ Glossary p36/ FICCI Security Department p38 Smart border management: Indian coastal and maritime security September 2017 www.pwc.in Dr Sanjaya Baru Secretary General Foreword 1 FICCI India’s long coastline presents a variety of security challenges including illegal landing of arms and explosives at isolated spots on the coast, infiltration/ex-filtration of anti-national elements, use of the sea and off shore islands for criminal activities, and smuggling of consumer and intermediate goods through sea routes. Absence of physical barriers on the coast and presence of vital industrial and defence installations near the coast also enhance the vulnerability of the coasts to illegal cross-border activities. In addition, the Indian Ocean Region is of strategic importance to India’s security. A substantial part of India’s external trade and energy supplies pass through this region. The security of India’s island territories, in particular, the Andaman and Nicobar Islands, remains an important priority. Drug trafficking, sea-piracy and other clandestine activities such as gun running are emerging as new challenges to security management in the Indian Ocean region. FICCI believes that industry has the technological capability to implement border management solutions. The government could consider exploring integrated solutions provided by industry for strengthening coastal security of the country. The FICCI-PwC report on ‘Smart border management: Indian coastal and maritime security’ highlights the initiatives being taken by the Central and state governments to strengthen coastal security measures in the country. -

Department of Zoology and Aquaculture, Acharya Darwin Ch. and P Padmavathi Nagarjuna University Nagarjuna Nagar, Abstract Andhra Pradesh, India Among the various groups represented in the macrobenthic fauna of the Bay of Bengal at Prakasam P Padmavathi district, Andhra Pradesh, India, molluscs were the dominant group. Molluscs were exploited for Department of Zoology and industrial, edible and ornamental purposes and their extensive use has been reported way back from time Aquaculture, Acharya immemorial. Hence the present study was focused to investigate the diversity of Molluscan fauna along Nagarjuna University the Paleru and Moosy backwaters of Prakasam district during 2016-17 as these backwaters are not so far Nagarjuna Nagar, explored for malacofauna. A total of 23 species of molluscs (16 species of gastropods belonging to 12 Andhra Pradesh, India families and 7 species of bivalves representing 5 families) have been reported in the present study. Among these, gastropods such as Umbonium vestiarium, Telescopium telescopium and Pirenella cingulata, and bivalves like Crassostrea madrasensis and Meretrix meretrix are found to be the most dominant species in these backwaters. Keywords: Malacofauna, diversity, gastropods, bivalves, backwaters 1. Introduction Molluscans are the second largest phylum next to Arthropoda with estimates of 80,000- 100,000 described species [1]. These animals are soft bodied and are extremely diversified in shape and colour. -
Arabian Sea and the Gulf of Oman by Global Ocean Associates Prepared for Office of Naval Research – Code 322 PO
An Atlas of Oceanic Internal Solitary Waves (February 2004) Arabian Sea and the Gulf of Oman by Global Ocean Associates Prepared for Office of Naval Research – Code 322 PO Arabian Sea and the Gulf of Oman Overview The Arabian Sea is located in the northwest Indian Ocean. It is bounded by India (to the east), Iran (to the north) and the Arabian Peninsula (in the west)(Figure 1). The Gulf of Oman is located in the northwest corner of the Arabian Sea. The continental shelf in the region is widest off the northwest coast of India, which also experiences wind-induced upwelling. [LME, 2004]. The circulation in the Arabian Sea is affected by the Northeast (March-April) and Southwest (September -October) Monsoon seasons [Tomczak et al. 2003]. Figure 1. Bathymetry of Arabian Sea [Smith and Sandwell, 1997]. 501 An Atlas of Oceanic Internal Solitary Waves (February 2004) Arabian Sea and the Gulf of Oman by Global Ocean Associates Prepared for Office of Naval Research – Code 322 PO Observations There has been some scientific study of internal waves in the Arabian Sea and Gulf of Oman through the use of satellite imagery [Zheng et al., 1998; Small and Martin, 2002]. The imagery shows evidence of fine scale internal wave signatures along the continental shelf around the entire region. Table 1 shows the months of the year when internal wave observations have been made.

The Natural Choice for Wildlife Holidays Welcome
HOLIDAYS WITH 100% FINANCIAL PROTECTION The natural choice for wildlife holidays Welcome After spending considerable time and effort reflecting, questioning what we do and how we do it, and scrutinising the processes within our office and the systems we use for support, I am delighted to say that we are imbued with a new vigour, undiminished enthusiasm, and greater optimism than ever. My own determination to continue building on the solid foundation of twenty years of experience in wildlife tourism, since we started from very humble beginnings – to offer what is simply the finest selection of high quality, good value, tailor-made wildlife holidays – remains undaunted, and is very much at the core of all we do. A physical move to high-tech office premises in the attractive city of Winchester leaves us much better connected to, and more closely integrated with, the outside world, and thus better able to receive visitors. Our team is leaner, tighter, more widely travelled and more knowledgeable than ever before, allowing us to focus on terrestrial, marine and – along with Dive Worldwide – submarine life without distraction. In planning this brochure we deliberately set out to whet the appetite, and make no mention of either dates or prices. As the vast majority of trips are tailored to our clients’ exact requirements – whether in terms of itinerary, duration, standard of accommodation or price – the itineraries herein serve merely as indications of what is possible. Thereafter, you can refine these suggestions in discussion with one of our experienced consultants to pin down your precise needs and wants, so we can together create the wildlife holiday of your dreams. -

Perennial and Non-Perennial River- River Originating from Mountains, They Get Water Throughout the Year, That River Consider As Perennial River
Perennial and Non-Perennial river- River originating from mountains, they get water throughout the year, that river consider as Perennial river. on the other hand river originating from plateau region called Non-Perennial river. these river do not have enough water for the whole year. Peninsular river- They have a large seasonal fluctuation in volume as they are solely fed from rainfall. These river flow in valley with steep gradients. the river which end in the Bay of Bengal are called 'East flowing' river, If the river empties into the Arabian sea, it is called ' West flowing' river. Inland drainage river- The river which does not empty itself into any sea, and end with any lake or any other water body is known as Inland Drainage river.
