Aravalli Range March 31, 2021 About Aravalli The Aravallis of Northwestern India, one of the oldest fold mountains of the world, now form residual mountains with an elevation of 300m. to 900m. They stretch for a distance of 800 km. from Himmatnagar in Gujarat to Delhi, spanning Haryana, Rajasthan, Gujarat, and Delhi, the 692 kilometre (km). It is the oldest fold of mountain ranges in the world stretching about 300 miles from the northeast to the southwest. The Aravalli range is very rich in natural resources and gave rise to numerous peninsula rivers like Banas, Luni, Sakhi, and Sabarmati. Guru Shikhar is the highest point in the range which is located in Mount Abu. The Aravallis date back to millions of years when a pre- Indian subcontinent collided with the mainland Eurasian Plate. Significance of Aravalli Barrier between the fertile plains in the east and the sandy desert in the west. Aravalli range checked the spread of the Thar desert towards the Indo-Gangetic plains, serving as a catchment of rivers and plains. Rich in biodiversity and provides habitat to 300 native plant species, 120 bird species and many exclusive animals like the jackal and mongoose. Aravallis function as a groundwater recharge zone for the regions around that absorb rainwater and revive the groundwater level. During monsoons, it provides barrier and monsoon clouds move eastwards towards Shimla and Nainital, thus helping nurture the sub-Himalayan rivers and feeding the north Indian plains. During winter, it protects the fertile alluvial river valleys from the cold westerly winds from Central Asia. .

CENTRAL GROUND WATER BOARD MINISTRY OF WATER RESOURCES, RIVER DEVELOPMENT AND GANGA REJUVINATION GOVERNMENT OF INDIA GROUND WATER YEAR BOOK OF HARYANA STATE (2015-2016) North Western Region Chandigarh) September 2016 1 CENTRAL GROUND WATER BOARD MINISTRY OF WATER RESOURCES, RIVER DEVELOPMENT AND GANGA REJUVINATION GOVERNMENT OF INDIA GROUND WATER YEAR BOOK OF HARYANA STATE 2015-2016 Principal Contributors GROUND WATER DYNAMICS: M. L. Angurala, Scientist- ‘D’ GROUND WATER QUALITY Balinder. P. Singh, Scientist- ‘D’ North Western Region Chandigarh September 2016 2 FOREWORD Central Ground Water Board has been monitoring ground water levels and ground water quality of the country since 1968 to depict the spatial and temporal variation of ground water regime. The changes in water levels and quality are result of the development pattern of the ground water resources for irrigation and drinking water needs. Analyses of water level fluctuations are aimed at observing seasonal, annual and decadal variations. Therefore, the accurate monitoring of the ground water levels and its quality both in time and space are the main pre-requisites for assessment, scientific development and planning of this vital resource. Central Ground Water Board, North Western Region, Chandigarh has established Ground Water Observation Wells (GWOW) in Haryana State for monitoring the water levels. As on 31.03.2015, there were 964 Ground Water Observation Wells which included 481 dug wells and 488 piezometers for monitoring phreatic and deeper aquifers. In order to strengthen the ground water monitoring mechanism for better insight into ground water development scenario, additional ground water observation wells were established and integrated with ground water monitoring database.

Chapter 1 Introduction 1.1
. CHAPTER 1 INTRODUCTION 1.1. Brief background: Biodiversity may be defined as the richness of species of plants, animals, and microorganisms in any given habitat such as land, water (fresh or saline including seas) or as parasites or symbionts. It is a product of evolution over millions of years. It may be subdivided into three categories – genes, species, and ecosystem. Genetic diversity refers to the variations in the genes within a species. This covers distinct populations of the same species (for example we have thousands of traditional varieties of rice in India.). The term Species diversity refers to the populations of different plants, animals, and microorganisms in a given habitat, existing as an interacting system. They are also referred to as communities. An aggregate of communities occurring as an interacting system in a given ecological niche makes an Ecosystem Biodiversity is the source of all living materials used as food, shelter, clothing, biomass energy, medicaments, and host of other raw materials used in bio-industrial development. Thus, the ecology & economy of the country depends upon the status of its Biodiversity. India is predominantly a biomass-based country with largely bio-industrial pattern of development. Our stakes in biodiversity are high. There is an increasing pressure on natural resources due to growing human population and enhanced pace of socio-economic development. This has led to degradation of habitats and has resulted in loss of biodiversity and agricultural productivity. Biodiversity is an irreplaceable resource: its extinction is forever. Such loss of species affects not only the plants, animals and microorganisms in nature together with those under cultivation / domestication and used in industry, but also species whose values are yet to be ascertained.

Appeal to Resume Mining in Aravalli Hills
Appeal to Resume Mining in Aravalli Hills drishtiias.com/printpdf/appeal-to-resume-mining-in-aravalli-hills Why in News Recently, the Haryana government has appealed to the Supreme Court to permit it to resume mining in the Aravalli Hills on the grounds that the pandemic had grounded the State’s economy to a halt. Key Points 1/4 About the Aravalli Range: Location: They stretch for a distance of about 720 km from Himmatnagar in Gujarat to Delhi, spanning Haryana, Rajasthan, Gujarat, and Delhi. Formation: The Aravallis date back to millions of years when a pre-Indian subcontinent collided with the mainland Eurasian Plate. Age: Carbon dating has shown that copper and other metals mined in the ranges date back to at least the 5th century BC. Characteristics: The Aravallis of Northwestern India, one of the oldest fold mountains of the world, now form residual mountains with an elevation of 300m to 900m. Guru Shikhar Peak on Mount Abu is the highest peak in the Aravalli Range (1,722 m). It has been formed primarily of folded crust, when two convergent plates move towards each other by the process called orogenic movement. Extension: The mountains are divided into two main ranges – the Sambhar Sirohi Range and the Sambhar Khetri Range in Rajasthan, where their extension is about 560 km. The hidden limb of the Aravallis that extends from Delhi to Haridwar creates a divide between the drainage of rivers of the Ganga and the Indus. 2/4 Their Significance: Checks Desertification: The Aravallis act as a barrier between the fertile plains in the east and the sandy desert in the west.

I Government of India Copyright 1988 ~ lift m<::a ~~-99ooo9 HOME MINISTER INDIA NEW DELHI-110001 Oct. 26, 1988 FOREWORD Experience has taught us that planning has to be related to the situation in the field in order to better respond to local aspirations and for better utilization of local resources. A lot of planning has, of necessity, to be for larger areas, encompassing an agglomeration of administrative units. Even such macro planning has, in order to be realistic, to be cognisant of the realities at the micro level. Correspondingly, such plans for bigger areas and involving larger outlays have also to be administered from a suitably high threshold of administrative authority and by a wide network of administrative hierarchy. Nevertheless, there is a whole corpus of activities which can be and are, in fact, better planned, conducted and financed at the lower or local levels.

Conservation of Natural Resources Through
CONSERVATION OF NATURAL RESOURCES THROUGH PRACTICE OF ECOTOURISM IN ARAVALLI RANGES OF GURUGRAM DISTRICT Shashi Mehta1 Amity School of Architecture & Planning, Amity University, Haryana, (India) ABSTRACT Tourism has become the main source of income in developing countries by generating revenues and also provides employment especially for unskilled labor and migrants. The undulating topography of hill not only provides the scenic beauty but also act as lungs for the entire National Capital Region, Delhi (NCR). The dry area of Aravalli range are getting maximum consideration due to the exploitation of existing natural resources in Gurugram district. Inspite of having rich resources, are being exploited by the industrialists, real estate developers, land mafia, government etc. The highways and the two other major projects are under pipeline (DFC and KMP) passing through the district resulted into bifurcation of natural habitat. Apart from this several other development activities in the form of encroachment like farmhouses, resorts etc built on forest land and commercially exploited the area. Thus, there is a mismatch between environment and development has been noticed in the region which will further affect the ecological balance. Thus, the idea of developing Aravalli ranges as an ecotourism centre will conserve the natural resources and ameliorate problems related to environmental degradation in district and required a strong institutional mechanism to restrict the prevailing illegal activities. I. INTRODUCTION Tourism has also become the main source of income in developing countries by generating revenues accompanied with investment in infrastrucutre like roads, airport, water and sewerage facilities. It also provides employment especially for unskilled labor and migrants from poor rural areas in different sectors such as construction, agriculture etc.

Central Highland
CENTRAL HIGHLAND D.K. Upadhyay Sir ARAWALI RANGE Aravalli is a mountain range located in the western part of India, Rajasthan. Aravalli is the oldest mountain in the geographical structure of India. It is the oldest mountain range in the world, which divides Rajasthan from north to south in two parts. The highest mountain peak of Aravali is Gurushkhat (1722/1727 m) in Sirohi district, which is in Mount Abu (Sirohi). The Bhil tribe has lived in the vicinity of the Aravalli ranges for centuries. The estimated age of the Aravalli mountain range is 570 million years. This is an example of a residual mountain with a total length of about 692 km from Gujarat to Delhi, about 40% of the Aravali mountain range is in Rajasthan, Rashtrapati Bhavan located in Delhi on the Raisina hill. It is a part of the Aravalli mountain range, the average elevation of Aravalli is 930 meters and the height and width of the south of Aravali is the highest, Aravalli or Aravali is the north Indian ranges. Some rocky hills of this mountain covering 550 kilometers, passing through the northeastern region of the state of Rajasthan, have gone to the south part of Delhi. The ranges of peaks and cuttings, which span 10 to 100 kilometers, are generally 300 to 900 meters high. This range is divided into two parts - the Sambhar- Sirohi ranges - which consists mostly of high mountains including Guru Shikhar (peak of Aravalli ranges, in height (1,722 m) and (5649.606 ft) of Mount Abu). There are different cutaneous areas.

Current estimation shows that the earth is approximately 460 million years old. Over these long years, it has undergone many changes brought about primarily by the endogenic and exogenic forces. These forces have played a significant role in giving shape to various surface and subsurface features of the earth. Based on the variations in its geological structure and formations, India can be divided into three geological divisions. These geological regions broadly follow the physical features: I. The Peninsular Block II. The Himalayas and other Peninsular Mountains III. Indo-Ganga-Brahmaputra Plain The Peninsular Block The northern boundary of the Peninsular Block may be taken as an irregular line running from Kachchh along the western flank of the Aravalli Range near Delhi and then roughly parallel to the Yamuna and the Ganga as far as the Rajmahal Hills and the Ganga delta.
