Climate Change Impacts on Agricultural Production in Selected Revenue Villages in Madurai District of Tamil Nadu: An Economic Perspective

Abstract

In the long run, the climate change could affect agriculture in several ways such as quantity and quality of crops in terms of productivity, growth rates, photosynthesis and transpiration rates, moisture availability etc. Climate change is likely to directly influence the food production across the globe. An increase in mean seasonal temperature is likely to shorten the duration of many crops and thus reduce yields. In areas where temperature is already close to the physiological maxima for crops, warming will impact yields more immediately (IPCC, 2007). With this context, an attempt is made to analyze the production trend of agricultural sector in the selected revenue villages in Madurai district of Tamil Nadu. In the year of 2006-2007 grain and Pulses production was high level. In 2007-08 Pulses production was very low. In the 9 revenue villages which we took for research but, only 3 parts are produced in sugar crops. In the 3 villages, pulses production is zero. Most of the Sugar crops have been produced in the year 2007-08. In the year of 2007-08 more fruits and vegetables were produced. But in 2013-14 the fruits and vegetables are much lower and in 2009-10 it is much less. Oil seed Crops production is have been equally, with small differences in all years. In the year of 2007-08, more Oil seeds crops were produced. In the year 2012-13 the lowest produced with Oil seeds crops.
