Impact of climate change on growth and variability in area, production and productivity of major vegetables in India

Premlata Kumari, H. Basavaraja

Abstract


There are reasons to believe that climate change could affect agricultural productivity. It is predicted that a loss of 10 to 40 per cent in production may occur by 2100 due to climate change. Important vegetable crops grown in the country are tomato, onion, brinjal, cabbage, cauliflower, okra and peas. India contributes 13.38 per cent to the world vegetable production. This study was mainly based on secondary data from NHM database 2013 and data were analyzed using correlation coefficient, Compound Growth Rate [CGR], Markov analysis. The study revealed that for onion, area, production and productivity CGR was highest in the last ten years. Co-efficient of Variation [CV] was highest for tomato in the case of area and production but in the case of productivity CV was highest for brinjal. Correlation coefficient of area, production and productivity with rainfall, minimum temperature was negative and with maximum temperature it was positive
