Modeling of water use patterns

This pilot study was a landmark exercise; executed with low-cost java-enabled cell-phones and completed within 2 months, it generated 1.1 million records across 10 districts of the province. XForms technology was used to transform the traditional paper-based questionnaires into electronic forms that were rendered on the low-cost cell-phones to facilitate data collection.

In this paper, we employ analytical techniques to make inferences on water availability patterns, and the capacity of different villages in the region to sustain multiple crop cycles. By combining information from multiple sources, we show how the demographic composition of the villages is influenced by the availability of water.

Villages/Districts surveyed in Rajasthan

The Government of India frequently conducts surveys of its minor irrigation schemes, each of which covers a cultivable command area (CCA) of up to 2000 hectares.

This paper examines the data from a pilot water census of Rajasthan, which is India’s largest province by area; home to the Thar desert, a large part of the province experiences extreme heat. The pilot study was conducted in 2011 in 240 villages spanning 10 districts of Rajasthan.
