Exploring Rajasthan: Agro & Sub Agro Climatic Zones

As we all know, Rajasthan is thought of as the ‘Land of Kings’ may be a state in northern Bharat. It covers 342,239 sq. kilometres (132,139 sq mi), or ten.4 per cent of India’s total geographical region. It’s the biggest Indian state by space and the seventh-largest by population. In today’s article, we will discuss the Agro & Sub Agro climatic Zones of Rajasthan. Knowing Rajasthan agro climatic zones, semi-arid eastern plains of Rajasthan and the semi-arid region of Rajasthan.

Rajasthan

Rajasthan lay to the northwest of Bharat, simply higher than the Tropic of Cancer and settled between 23º30′ and 30º 11′ North latitude and 69º 29′ and 78º 17′ East meridian. 

The state shares its north-western and western boundary with the Indo-Pakistan international border that extends to 070 metric linear units and touches Barmer, Bikaner, and Ganganagar’s central districts, Jaisalmer.

Rajasthan is feathered on the north and northeast by the states of geographical area, Haryana, and province, east and southeast by the states of the province and Madhya Pradesh, and southwest to the state of Gujarat. The large portion of the state of Rajasthan is desiccated and homes the most important Indian desert-the Thar Desert, referred to as the ‘Maru-kantar’.

The oldest chain of fold mountains-the Aravali- splits the state into 2 geographical zones-desert on one aspect and forest belt on the opposite. These zones are classified on the basis of agro-climatic parameters agro-climatic zones by the Indian Council of Agricultural analysis (ICAR). Rajasthan has been divided into ten agro-climatic zones.

The Agro-climatic zones of Rajasthan are as follows:

1. Arid North-Western Sandy Plain

Sandy Arid Plain sixty of the whole space of W.S.P. has sandy land. The minimum downfall is concerning fifty Cm. Brobdingnagian expanses of sand & rock outcrop, principally stone, are found in Jaisalmer, Barmer, Bikaner, Churu, Hanumangarh & Sriganganagar.

2. Irrigated North Western Plain

This Plain extends within the northern part of the state in Ganganagar, Hanumangarh and the northwestern part of the Bikaner district.

Because the zone is irrigated by a network of statesman Canal, Bhakra and Gang canal, it’s intensively cultivated. The Plain is dominantly coated by the medium and fine unsmooth deep to terribly deep soils.

3. Hyper Arid Partial Irrigated Zone

The conventional downfall within the zone is 185 to 390 millimetres. This zone unfolds within the arid region of Bikaner, Jaisalmer and elements of Churu, wherever the farmers have partial dependence on the sources of irrigation. The region has soil characterised by dunes and aeolian soil.

4. Transmutation Plain of midland drain

The zone has an average downfall of 300-400mm. This Plain unfolds within the central part of the state, covering the western, jap and northern parts of Nagaur and the Sikar, Churu and Jhunjhunu districts. There is no drain out of this space. 

5. Deposit Plain of Luni Basin

Rainfall ranges between four hundred and 500 mm. The physiographic zone is found within the state’s central part, where various temporary streams and watercourse Luni and its tributaries flow through this space, covering Prakrit, Jalore, a part of Nagaur Jodhpur and Barmer districts. Water is saline during this zone.

6. Semi-Arid eastern plain of Rajasthan

The average downfall within the zone concerns 500- 700 mm. The area is two.96 million hectares. This Plain is drained by the watercourse Banas and its tributaries. The semi-arid eastern Plain is unfolded within the jap, a part of the state covering Jaipur, Ajmer, Dausa and Tonk districts. The Plain may be sandy. Occasional dunes, buried pediments, and scattered hills with substantial space underneath alluvion are options for this zone.

7. Flood Prone jap Plain

The downfall within the zone is 600-700 mm. This zone extends to Alwar, Bharatpur and Dholpur districts. Soils are yellowish-brown to dark brown, sandy soil to clay soil and non-calcareous. This zone developed on the alluvion deposited by the watercourse Yamuna and its tributaries and covers a part of the state.

8. Sub wet Southern Plain and Aravallis

The zone receives a 700-900 mm downfall. High hills are scattered through the zone. The zone extends within the southern part of the state in Bhilwara, Rajsamand, Sirohi, Udaipur and Chittorgarh districts.

9. Wet Southern Plain

This zone receives 900-1000 mm downfall. Hills and depression characterise this Plain within the southern part of the state in Dungarpur, Banswara and Pratapgarh districts. The hills are coated with a thick density of trees.

10. wet South jap Plain

This zone receives the best downfall within the state of around 700-1000 mm. South-eastern, a part of the state, covers Sawai Madhopur, Karauli, Jhalawar, Baran, Kota and Bundi districts.

Semi-arid Region

Rainfall ranges from twenty to forty cm. Winter is incredibly short and arid within the northern elements of this region. 

This region includes the western elements of Ganganagar, Hanumangarh, Jodhpur and Barmer districts. The possibility for drier conditions in arid and semi-arid regions is “very high”, resulting in severe water shortages. Additionally, stressed the vulnerability of certain regions that will be doubly exposed to the dangers of global climate change and economic processes. Ensure crop’s geographical shift to cooler areas can occur. A lot of carbon within the atmosphere may be useful for the crops; however, this impact is invalid because of the increase in temperatures. Changes in soil, increase in pesterer population and weeds are all inevitable with the increasing temperatures. Other possible impacts are modified in farm ecology, viz., bird-insect relation.

Conclusion

In this article, we have discussed the Agro & Sub Agro Climatic Zones of Rajasthan. By learning about the 10 divisions, students can study the semi-arid and semi-arid eastern plains in detail. By learning about this, we can conclude that climate variability directly impacts the water resources of the region. The low to medium rainfall in most parts, high evapotranspiration demands for water, high frequency of droughts resulting from the departure of rainfall from mean values, and the high per capita arable land increase the demand for irrigation water.
