Climate change is essentially a long term phenomenon and is supposed to be gradual in its impact for most part. Integrated assessment combining insights of many disciplines is used as a primary tool in order to follow the causal chain of events from perturbations in the environment to the final outcomes. This can be done by first assessing the vulnerability of different regions to climatic change and then quantifying its impact on agriculture using the long term data. The present paper applies a statistical methodology to rank the coastal districts of Tamil Nadu State, India in terms of vulnerability and to classify them into different levels of vulnerability by constructing composite vulnerability indices. Also the paper presents the impacts of climatic change on productivity and area under three major crops of Tamil Nadu by employing Ricardian model. Existing base level area and yields are obtained by substituting average values of the explanatory variables for each district in the area and yield regressions. Production levels could then be obtained as their product. Similarly, area and yield levels post HADCM3 A2a scenario climate change could be obtained by substituting base line linked climate variables, in respective regressions and assuming other variables at their current long term base levels. Production estimates could be obtained as the product of estimated area and yield levels. Such computations of base level area, yield and production and their 2020 and 2050 counterparts based on climate change were done for individual districts and then summarized for the state. As per Ricardian type regression based projections, climate change impact is projected to be between 4 to 13 percent in terms of reduction in both area and yields of major crops compared to the existing levels. Consequently overall crop production will be decreased up to 22 percent.
