Weather-based crop insurance scheme (WBCIS) products proposed by four insurance providers was compared and evaluated using historical weather data for piloting WBCIS on kharif groundnut in Coimbatore, Dharmapuri, Theni, Tirunelveli and Virudhunagar districts of Tamil Nadu. Water deficits during the vegetative phases of groundnut crop generally delay flowering and maturity thereby reducing the crop growth and yield. The study revealed that the deficit rainfall risk was more pronounced in all the abovementioned districts, whereas the risk of excess rainfall impact could be clearly observed in Theni district. Though the occurrence of strike events was for phase- I of deficit rainfall cover, the rate per mm of rainfall fixed by IFFCO-TOKYO was quite low. The product designed for HDFC-ERGO and MS-Cholamandalam was similar, whereas the product for AIC and IFFCO-TOKYO was designed with little variation in context to excess rainfall cover and consecutive dry days. The compensation benefit realized by the farmers of Virudhunagar and Dharmapuri districts was higher followed by Theni because the compensation rate per mm of rainfall fixed by the company was higher, which favours the farmers.Keywords

To assess the drought hazard for different agro-climatic zones of Tamil Nadu (TN), India, the present study deals with temporal trend and spatial pattern of drought over the period 1981–2019. Standardized Precipitation Index (SPI) has been used to detail the geographical variations of drought intensity, duration and frequency at multiple time steps. The spatial rainfall variability of the Southwest monsoon (SWM) ranged from 69.3 mm (Tuticorin) to 772.8 mm (the Nilgiris), and that for the Northeast monsoon (NEM) ranged from 277.8 mm (Krishnagiri) to 825.9 mm (Nagapattinam), while annual rainfall variability ranged from 558.8 mm (Tuticorin) to 1466.8 mm (the Nilgiris) for TN. Irrespective of all the regions, the frequency of moderate drought occurrence was higher compared to other drought nomenclature. The NEM season recorded on par and higher number of drought occurrences with respect to SWM season. Out of 39 years, TN experienced severely dry to extremely dry climate during 2002. The result underlines the potential of SPI in drought identification and also revealed that the rainfall is strongly linked to drought policies and measures implemented for the state.Keywords
