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 />
