2. Indian Desert-Size and Location
•Thar Desert, also called great Indian desert ,
located on the Indian subcontinent. It is
bounded by Aravali range in east and located
partly inRajasthan state, northwestern India,
and partly in Punjab and Sindh (Sind) provinces,
eastern Pakistan
•The desert stretches its area of 238,254km²
(77,000 sq mi).
•It is considered to be the 20
th
largest desert and
9
th
largest subtropical desertof the world.
•27.4695°N, 70.6217°E(Coordinates of the
centre of the desert)

3. Physical Features of Indian Desert
•The Indian desert lies on the western edge of the
hills of Aravalli.
•It is an undulating sandy plain surrounded by
dunes of sand.
•Very low rainfall, below 150 mm per year, occurs in
this area. With poor vegetation cover, it has an
arid atmosphere.
•During the rainy season, streams emerge. They
vanish into the sand shortly after, as they do not
have enough water.
•Barchans (crescent-shaped dunes) cover larger
areas, but along the Indo
•Pakistan border, longitudinal dunes are becoming
more prevalent.

4. Drainage in Indian desert
•There is one and only one river in thar Desert. That is
‘Luni’.
•The Luni is the largest river in the Thar Desert of
northwest India. It originates in the Pushkar valley of
the Aravalli Range, near Ajmer, passes through the
southeastern portion of the Thar Desert, and ends in
the marshy lands of Rann of Kutch in Gujarat, after
travelling a distance of 495 kilometres.
•It is hot, so streams appear only in rainy seasons ans
soon after, they disappear.
•Indra Gandi Canal is drawn from satluj to the desert
for peoples.
•Chambal (drains in Yamuna) is divided by Indian
Desert by Aravali Range.
•Dry rivers beds found here. Like of Ghaggar.

5. Climate
•he amount of annual rainfall in the desert is generally low, ranging from about 4
inches (100 mm) or less in the west to about 20 inches (500 mm) in the
east.Precipitationamounts fluctuate widely from year to year. About 90 percent of
the total annual rainfall occurs during theseasonof the southwest monsoon, from
July to September (see alsoIndian monsoon). During other seasons the prevailing
wind is the dry northeast monsoon. May and June are the hottest months of the
year, withtemperaturesrising to 122 °F (50 °C). During January, the coldest month,
the mean minimum temperature ranges between 41 and 50 °F (5 and 10 °C), and
frost is frequent.Dust stormsand dust-raising winds, often blowing
withvelocitiesof 87 to 93 miles (140 to 150 km) per hour, are common in May and
June
•It has a hot arid climate with unfertile sand. It has extreme climate.
•It is very hot in day and very cold in night.
•Due to high temperature, pressure is high in this area.

6. Natural vegetation and wildlife
•The desert vegetation is mostly herbaceous or stunted
scrub;drought-resistanttreesoccasionally dot the
landscape, especially in the east. On the hills, gum
arabicacaciaand euphorbia may be found.
Thekhajri(orkhejri) tree (Prosopis cineraria) grows
throughout the plains.
•The thickly
populatedgrasslandssupportblackbucks,chikara (gazelles),
and some featheredgame, notablyfrancolins(partridges)
andquail. Among the migratorybirds, sandgrouse,ducks,
andgeeseare common. The desert is also the home of the
endangered great bustard.
•The ship of the desert ‘camel’ found here useful for travel,
milk, fibre and has a great significance.

7. POPULATION (about peoples)
•Most of the desert’s inhabitants reside in rural areas and are
distributed in varying densities. BothIslamandHinduismare
practiced, and thepopulationis divided into complex economic and
social groups. The prevailing languages areSindhiin the
southwest,Lahndain the northwest, andRajasthani languages—
especially Marwari—in central and eastern portions of the Thar. The
ethniccompositionof the Thar isdiverse. Among the most
prominent groups are theRajputs, who inhabit the central Thar.
Many nomads are engaged in animal husbandry, crafts, or trade. In
general, thenomadsaresymbioticallyrelated to the sedentary
population and its economy.
•The Thar desert has a fairly high population density of 83 persons
per square km. Overall, it has a total population of16,600,000.

8. Importance of Thar Desert
•India has its natural borders. The himalayas shield us from the north, the great ocean from the
south and not to forget the THAR Desert from the west.
•TheThar desert has its own significance, in the present scenario it acts as a barrier between us and
pakistan. Any illegal pakistani infiltrators have to wade through the scorching desert which is very
less likely.
•Also the desert was used as a testing ground for India's earlier nuclear missiles (now Bay of Bengal)
•Same way our Border Security Force(BSF) along rajasthan is more experienced than anyone else on
how to use the desert as a strategic location to avoid infiltration. The BSF force along rajasthan uses
camels as their mode of transport. They are a familiar sight at the republic parade.
•Our Thar desert has following benefits
Security wise ,it is difficult to enter terrorists through desert
We used desert to test nuclear bombs
We used them to generate solar energy now,which develop great energy source
Different ethnicity because of desert.
Desert useful for different research purposes
Beneath our desert we have a oldest civilisation.
