  • Resettlement in Narmada River Basin Evolution of Resettlement Policy in India
    Resettlement in Narmada River Basin Evolution of Resettlement Policy in India Uday Shelat Professor, Department of Architecture and Planning The Maharaja Sayajirao University of Baroda, India Abstract The present paper examines the problems of resettlement of people affected by a large-scale water resource development project in India. At present there is no resettlement policy at the national level, but the Government of Gujarat has evolved resettlement policies for the Saradar Sarovar Project on the river Narmada. The attempt has been made to look into the policies, strategies and implementation process i.e., efforts made by the state government to resettle the project-affected people in the new habitats. Finally, the paper depicts recommendations and suggestions to strengthen the resettlement process. Introduction India after independence embarked on an ambitious programme of economic development. Nation faced twin problems of unemployment and poverty to begin with. The land was rich with diverse natural resources but was unharnessed. The crucial task was to channelize these resources- land, water, minerals, forests, and sea wealth so as to transform them into productive wealth for the people. India has unique geographic situation where arable land is spread out stretching from Kutch to Brahmputra valley and from Deccan trap to plains of Punjab, while bulk of surface water sources are concentrated in about dozen river basins; and 80% of surface water is available only in monsoon months which flows down the sea if not impounded. Therefore neither water nor land is utilised optimally, depriving the country of their full benefits. The Saradar Sarovar Project (SSP) on river Narmada was conceived keeping these potentials.

  • Estimation of Paleo-Discharge of the Lost Saraswati River, North West India
    EGU2020-21212 https://doi.org/10.5194/egusphere-egu2020-21212 EGU General Assembly 2020 © Author(s) 2021. This work is distributed under the Creative Commons Attribution 4.0 License. Estimation of paleo-discharge of the lost Saraswati River, north west India Zafar Beg, Kumar Gaurav, and Sampat Kumar Tandon Indian Institute of Science Education and Research Bhopal, Earth and Environment Sciences, India ([email protected], [email protected], [email protected] ) The lost Saraswati has been described as a large perennial river which was 'lost' in the desert towards the end of the 'Indus-Saraswati civilisation'. It has been suggested that this paleo river flowed in the Sutlej-Yamuna interfluve, parallel to the present-day Indus River. Today, in this interfluve an ephemeral river- the Ghaggar flows along the abandoned course of the ‘lost’ Saraswati River. We examine the hypothesis given by Yashpal et al. (1980) that two Himalayan-fed rivers Sutlej and Yamuna were the tributaries of the lost Saraswati River, and constituted the bulk of its paleo-discharge. Subsequently, the recognition of the occurrence of thick fluvial sand bodies in the subsurface and the presence of a large number of Harappan sites in the interfluve region have been used to suggest that the Saraswati River was a large perennial river. Further, the wider course of about 4-7 km recognised from satellite imagery of Ghaggar-Hakra belt in between Suratgarh and Anupgarh in the Thar strengthens this hypothesis. In this study, we have developed a methodology to estimate the paleo-discharge and paleo- width of the lost Saraswati River.

  • 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.

    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.
