Abstract
Coconut production from the small plantation crop holders of rural areas plays an essential role in the Indian economy. Tamil Nadu is the state which holds the pride of being the largest makers of coconut in the nation. Climatic conditions of the state ensure the considerable production for several years. At present, variability in climate worsens the survival conditions of coconut palm. This paper makes the spatial assessment of climate variability effects on coconut crop felt in Dindigul and Attur Taluks of Dindigul District, Tamil Nadu State, through applying geospatial technologies. This study is carried out by analyzing the climatic parameters and coconut production statistics for the years 2005 to 2014. The proposed area of study has 4,488.16 hectares of coconut plantations on rural areas out of 1,39,415 hectares of total surface area. Increased temperature trends and poorest rainfall patterns faced during the years 2009–2013 influenced coconut productivity negatively on account of lowering the ground water levels. Spatial damage assessment is carried out by using LISS III, IV and high-resolution images. It is identified that the inter-annual disparity of coconut production of 2010–2014 could be evidenced the aberrations due to continuous decline in seasonal rainfall and heavy summer air temperature conditions. This trend was not altered the favorable environs for flowering and growing of coconuts but it claimed lives of coconut trees. Results have showed that the climate and production are interrelated and the annihilation of rural economy because of loss of coconut lives could not be recoverable.
