Résumé partiel
Climate change pose a challenge to the world’s agricultural and natural resource systems which are already finding it difficult to cope with the growing food demand driven by population growth and higher purchasing power in developing countries. The challenge is compounded by the uncertainty and pace of climate change and its regional effects. It has been increasingly evident that climate change affects agricultural productivity. Changes in temperature and precipitation will require farmers to adapt, but precisely where and how much is uncertain. In India 65 per cent of agricultural area comes under rainfed farming and more than 60 per cent of the total population depends on agriculture, which is the most vulnerable to climate change. The study aims to analysing the impacts of climate variability on agricultural production in agro climatic zones of Tamil Nadu and to understand the farmer’s adaptation strategies to climate variability. The specific objectives of the study were to study the relationship between climate variability and agricultural production, to predict how future climate would affect agriculture production and to study the coping behavior and adaptation strategies of farm households with respect to climate variability. Tamil Nadu falls into eight agro climatic zones named as North East, North West, Western, Cauvery Delta, South, Southern, High Precipitation and High Altitude Zones. Among the eight zones the present study focuses on the first six zones of Tamil Nadu and excludes High Precipitation and Hilly Zones which occupy less than four per cent of the geographic area. Among six zones, Southern Zone which is highly vulnerable to climate variability was selected to study the coping behavior and adaptation strategies to climate variability. The Southern Zone encompass of Virudhunagar, Thoothukudi and Thriunelveli districts. One block was purposively selected from each of the selected districts considering the maximum per cent of area under un-irrigated agriculture. From each of the three blocks selected, three villages were selected at random. 20 farm households were randomly drawn from each of the nine villages, totaling a sample of 180 respondents for the study.
