2. A Profile of the State of Rajasthan<br />

2. Profile of the State of Rajasthan<br />

An overview of the socio-economic profile of the state and the important changes that have taken place<br />

in its economy are important to understand and map the multiple dimensions of food security in<br />

Rajasthan. This chapter highlights the geographical features of the state, and discusses its relative<br />

position in key areas of the economy.<br />

2.1 Agro-Climatic Regions<br />

On the basis of climatic conditions and agricultural produce, Rajasthan has been divided into nine agroclimatic<br />

zones, each one having special characteristics of its own.<br />

(i) Arid Western Plain<br />

This region comprises Bikaner, Jaisalmer and Barmer districts, and some tehsils of Jodhpur and Churu<br />

districts. This is the most arid part of the state where the annual rainfall varies from 10 to 40 cms, and<br />

is quite erratic, so much so, that the entire rainfall of the year may fall on a single day and the rest of the<br />

year may be dry.<br />

(ii) Irrigated North-Western Plains<br />

Hanumangarh and Ganganagar districts which consist of an alluvial and aeolian plain form this agroclimatic<br />

zone. A part of this region which is arid, is the northern extension of the Indian Thar Desert<br />

covered with wind-blown sand. Extreme aridity marked with high summer and low winter temperatures<br />

is its usual climatic characteristic. Due to abundance of canal water irrigation, this region has today<br />

become the granary of Rajasthan.<br />

(iii) Transitional Plain of Inland Drainage<br />

This zone comprises Nagaur, Sikar and Jhunjhunu districts and some tehsils of Churu district. The area<br />

is covered with sand dunes and inter-dunal sandy plains. Climatically, this zone is slightly more wet as<br />

compared to the adjoining Arid Western Plain.<br />

(iv) Transitional Plain of Luni Basin<br />

This area lies between the Aravalli ranges and western arid region. The region encompasses the entire<br />

districts of Jalore and Pali and some tehsils of Sirohi and Jodhpur districts. The region has semi-arid<br />

climate with an annual rainfall of 30 to 50 cms. It is drained by the river Luni which flows only during the<br />

rainy season.<br />

(v) Semi-Arid Eastern Plain<br />

This region comprises of four districts namely, Jaipur, Dausa, Tonk and Ajmer, which form a rich fertile<br />

plain. On the western side, the region is flanked by the low Aravalli hills which extend from the southwest<br />

to the north-east.<br />
