This paper by the Institute for Resource Analysis and Policy attempts a reality check on the ‘miracle growth’ in Gujarat’s agricultural production by looking at the gross value of the outputs from agriculture over a reasonably long period of time. The agricultural ‘growth’ seen in the recent past in Gujarat is nothing but a good recovery from a major dip in production occurred during the drought years of 1999 and 2000, because of four consecutive years of successful monsoon and bulk water transfer through the Sardar Sarovar project. The real ‘miracle growth’ in Gujarat’s agriculture appears to have occurred during the period from 1988 to 1998.

The study deals with identification of water quality monitoring sites on Kshipra river of Ujjain. The location of permanent sampling station is probably the most critical factor in a monitoring network which collects water quality data. If the samples collected are not representative of the water mass, the frequency of samplings as well as the mode of data interpretation and presentation become inconsequential.Read More

The report presents guidelines for hydrological investigations in a small watershed. A watershed is an individual entity, and is a naturally occurring unit of the landscape, which contains a complex array of interlinked and interdependent resources and activities irrespective of political boundaries. In addition, it is logical unit having readily identifiable boundaries and characteristics of water movement, which helps in coordinated planning and management.Read More

The report presents development of a sensor system capable of automated measurement of soil-water status, using the four-electrode resistivity (VES) method, in a soil profile. In this method, by changing the separation between two electrodes (metallic rods) placed at the ground surface without digging any holes, the variation in moisture content in the sub-surface soil profile can be monitored.Read More
