Climate Change is a global crisis. It is estimated, by the inter-governmental panel on climate change, that there will be increase in global mean temperature of about 1ºC above the present value by the year 2025 and 3ºC before the end of next century. In the present study, an attempt was made to investigate the cause of poor production of rice in 2008-09 in Navsari, Gujarat as compare to 2007-08, 09-10, 10-11 & 2011-12. Metrological data since 2003 was analyzed and compared with the data of 2008-09 and comparison was made to find the abnormality in rice crop productivity. It was found that during 2008-09, there were changes in metrological parameters (viz. rainfall, temperature, relative humidity, evaporation rate etc.) which disturbed the crop physiology indirectly affecting the yield of rice. The combined effect of rainfall and temperature was on relative humidity that created conducive atmosphere for insect and pest attacks on crops. Due to changes in temperature and relative humidity, evaporative water demands would have further aggravated the watering needs of crop. The study concludes that erratic monsoon or delayed monsoon hampers crop physiology ultimately yield due to erratic weather conditions. Further, such changes in rice growing areas could form the basis of planning and decisions on pricing, crop insurance, export and import policies of rice crop.
