The term “geography” comes from the ancient Greeks. In Greek, geo means earth and graphy means to write. Greeks developed an understanding of where their homeland was located in relation to other places and how people and environments were distributed by using geography.
Geography is the study of places and the relationships between people and their environments. Geographers explore both the physical properties of Earth’s surface and the human societies spread across it. They also examine how human culture interacts with the natural environment and the way those locations and places can have an impact on people. Geography seeks to understand where things are found, why they are there and how they develop and change over the time. Introduction Geography of Rajasthan
The natural resources of a country are of primary importance for the economic development. As a matter of fact, natural resources determine the economic life of a nation. Introduction Geography of Rajasthan
Man may grow rich in knowledge and intelligence, however much he may have overcome nature but ultimately he will have to depend on the materials supplied by Mother Nature for the development of his economic life.
The physical factors like topography, soils, geologic formation, climate and the available flora and fauna are the basic influences which lead to differences in land-use, cropping pattern, settlement and density of population and occurrence of minerals, water and power resources in different parts of the country. Introduction Geography of Rajasthan
Geography also became an important part of other academic disciplines, such as chemistry, economics and philosophy. In fact every academic subject has some geographic connection and the study where certain chemical elements such as gold or silver can be found. Economists examine which nations trade with other nations and what resources are exchanged.
Some people have trouble to understanding the complete scope of the discipline of geography because unlike most other disciplines, geography is not defined by one particular topic. The geography is concerned with many different topics—people, culture, politics, settlements, plants, land forms and much more.
What distinguishes geography is that, it approaches the study of diverse topics in a particular way. Geography asks spatial questions—how and why things are distributed or arranged in particular ways on Earth’s surface. It looks at these different distributions and arrangements at many different scales. It also asks questions about how the interaction of different human and natural activities on earth’s surface shape the characteristics of the world in which we live.
Geography seeks to understand where things are found and why they are present in those places; how things that are located in the same or distant places influence one another over time; and why places and the people who live in them develop and change in particular ways. Raising these questions is at the heart of the “geographical perspective.”
The study of geography is so broad; the discipline is typically divided into specialties. At the broadest level, geography is divided into physical geography, human geography, geographic techniques and regional geography. Introduction Geography of Rajasthan
The natural environment is the primary concern of physical geographers, although many physical geographers also look at how humans have altered natural systems. Physical geographers study Earth’s seasons, climate, atmosphere, soil, streams, landforms and oceans. Some disciplines within physical geography include geomorphology, glaciology, Pedology, hydrology, climatology, biogeography and oceanography.
Geomorphology is the study of landforms and the processes that shape them. Geomorphologists investigate the nature and impact of wind, ice, rivers, erosion, earthquakes, volcanoes, living things, and other forces that shape and change the surface of the Earth.
Glaciologists focus on the Earth’s ice fields and their impact on the planet’s climate. Glaciologists document the properties and distribution of glaciers and icebergs. Data collected by glaciologists has demonstrated the retreat of Arctic and Antarctic ice in the past century. Introduction Geography of Rajasthan
Pedologists study soil and how it is created, changed and classified. Soil studies are used by a variety of professions from farmers analyzing field fertility to engineers investigating the suitability of different areas for building heavy structures.
Hydrology is the study of Earth’s water: its properties, distribution and effects. Hydrologists are especially concerned with the movement of water as it cycles from the ocean to the atmosphere then back to Earth’s surface. Hydrologists study the water cycle through rainfall into streams, lakes, the soil and underground aquifers.
Climatologists study Earth’s climate system and its impact on Earth’s surface. For example: climatologists make predictions about El Nino- a cyclical weather phenomenon of warm surface temperatures in the Pacific Ocean. They analyze the dramatic worldwide climate changes caused by El Nino, such as flooding in Peru, drought in Australia and in the United States, the oddities of heavy Texas rains or an unseasonably warm Minnesota winter.
Biogeographers study the impact of the environment on the distribution of plants and animals. For example: a biogeographer might document all the places in the world inhabited by a certain spider species and what those places have in common.
Oceanography is a related discipline of physical geography, focuses on the creatures and environments of the world’s oceans. The discovery and tracking of the Gulf Stream helped communications and travel between Europe and the Americas. Introduction Geography of Rajasthan
Human geography is concerned with the distribution and networks of people and cultures on Earth’s surface. A human geographer might investigate the local, regional and global impact of rising economic powers China and India, which represent 37 percent of the world’s people. They also might look at how consumers in China and India adjust to new technology and markets and how markets respond to such a huge consumer base. Introduction Geography of Rajasthan
Human geographers also study how people use and alter their environments. When people allow their animals to overgraze a region, the soil erodes and grassland is transformed into desert. The impact of overgrazing on the landscape as well as agricultural production is an area of study for human geographers. Introduction:Geography of Rajasthan
The Republic of India is a vast country. It lies entirely in the northern hemisphere. The mainland of the country extends between latitudes 8°4′ and 37°6′ north, longitude 68°7′ and 97°25′ east. Introduction Geography of Rajasthan

Introduction of Rajasthan
The Rajasthan state was earlier known as Rajputana came into existence on March 30, 1949.
Rajasthan, situated at the northwestern part of India is the biggest state in the country of India and lies between 23°30′ and 30° 11′ North latitude and 69° 29′ and 78° 17′ East longitude. The state shares its north-western and western boundary with the Indo-Pakistan international border that extends about 1,070 km and touches the major districts Barmer, Bikaner, Sriganganagar and Jaisalmer. It is bounded on the west and northwest by Pakistan, on the north and northeast by Haryana &Uttar Pradesh, on the south-southeast and southwest by Madhya Pradesh and Gujarat States respectively. The huge portion of the state of Rajasthan is desiccated and houses the biggest Indian desert- the Thar desert known as the ‘Maru-kantar’. The oldest chain of fold mountains- the Aravali range splits the state into two geographical zones- desert at one side and forest belt on the other. Only 10% of the total geographical region lies under forest vegetation. The Mount abu is the only hill station of the state and houses the Guru Shikhar Peak that is the highest peak of the Aravali range with an elevation of 1,722 m. The area to the east of the hills is covered by the eastern plains and the Vindhyan plateau. Introduction Geography of Rajasthan
The north-western state of Rajasthan is the largest indian state with an area of 3, 42,239sq.km comprising of the 10.74% of the total geographical area of the country. This state has a type of rhomboid shape and stretches lengthwise 869 km. from west to east and 826 km. from north to south. The Tropic of Cancer passes through its south tip in its Banswara district.
The Aravalli ranges are india’s oldest fold mountains. The north end of the Aravalli range continues as secluded hills and rocky ridges into Haryana and ending in Delhi. Introduction Geography of Rajasthan
The Aravalli Range and the lands to the east and southeast of the range are generally more fertile and better watered. This region is home to the Kathiawar-Gir dry deciduous forests eco-region with tropical dry broadleaf forests that include teak, Acacia and other trees. The hilly Vagad region lies in southernmost Rajasthan on the border with Gujarat. With the exception of Mount Abu, Vagad is the wettest region in Rajasthan and the most heavily forested. North of Vagad lays the mewar region home to the cities of Udaipur and Chittaurgarh in Rajasthan. The Hadoti region lies to the southeast on the border with Madhya Pradesh. The dhundhar region is located in the north of Hadoti and mewar is also known as home to the state capital of Jaipur in Rajasthan. Mewat, the easternmost region of Rajasthan borders with Haryana and Uttar Pradesh. Eastern and southeastern Rajasthan is drained by the Banas and Chambal rivers, tributaries of the Ganges.
The Aravalli outline most important divisions of
Rajasthan. The Chambal River which is the only large and perennial river
in the state originates from its drainage to the east of this range and flows
northeast. Its principal tributary the Banas rises in the Aravali near
Kumbhalgarh and collects all the drainage of the Mewar plateau. Farther in
north the Banganga after rising near Jaipur in Rajasthan flow east-wards before
disappearing. The Luni is the only significant river located in west of the
Aravali. It rises in the Pushkar valley of Ajmer and flows 320 km
west-southwest into the Rann of Kachchh. Northeast of the Luni basin in the
Shekhawati tract, is an area of internal drainage characterized by salt lakes,
the largest of which is Sambhar Salt Lake.
Rajasthan has varying topographic features though a major part of the state is dominated by parched and dry region. The extensive topography includes rocky terrain, rolling sand dunes, wetlands and barren tracts of land filled with thorny scrubs, river-drained plains, plateaus, ravines and wooded regions.
Rajasthan has its important role in drainage system and some very useful rivers flow /originates through rajasthan. Chambal, Banas, Sabarmati, Mithari, Parbati, Berach, Saraswati, Jawai and Luni Rivers are important.
The soil and vegetation of Rajasthan
alters with its wide-ranging topography of the state and the availability of
water. The varied kind of soils available in Rajasthan are mostly sandy,
saline, alkaline and chalky (calcareous). Clay, loamy, black lava soil and
nitrogenous soils are also found.
The seasonal vegetation such as a few grass species, shrubs and dwarf trees can be found owing to the limited rainfall. However food crops are grown in the plains that are drained by the rivers and streamlets owing to the alluvial and clay soil deposits. The hilly tracts of the Aravali are characterized by the black, lava soils that sustain the growth of cotton and sugarcane.
The Thar desert or the Great Indian desert encompasses about 70% of total landmass of Rajasthan and hence it is identified as the “Desert State of India”. The Rajasthan desert which forms a major portion of the Thar desert is the biggest desert in India and encompasses the districts of Jaisalmer, Barmer, Bikaner and Jodhpur. In fact the Rajasthan desert comprises the desert triangle of three cities – Jaisalmer, Bikaner and Jodhpur. Thar desert extends from Sutlej River bounded by aravali ranges on the eastern part and on the southern part by the Great Rann of Kutch and on the western side by the Indus river. Introduction Geography of Rajasthan
The desert becomes very hot during the summer and it experiences extreme climate with an average annual rainfall less than 25 cm. Days are hot and the nights are cold here. The Vegetation consists of thorny bushes, shrubs and xerophilious grass. Various species of lizards and snakes are found here.
Rajasthan has varying climate like its varying topography. The weather and climate of the Rajasthan can be broadly classified into four distinct seasons. They are – Pre-monsoon, which is the hot season preceding the monsoon and extends from April to June, the Monsoon that occurs in the month of June in the eastern region and mid- July in the western arid regions. The Post-monsoon that commences from mid-September and continues till November and the winter that extends from December to March while January being the coldest month of the year. The average temperature in winter ranges from 8° to 28° C and in summer the average temperature range from 25° to 46° C.
