July 2016


Meterological data on temperature and rainfall for the period of 30 years was analysed using statistical tools to see the periodical deviation of climate. The impact of changing climate on mountain agriculture has been reviewed. Gradual increase in minimum and maximum temperature was observed whereas magnitude of increase in maximum temperature is more than minimum. There has not been steady increase in rainfall indicating higher variability. The increased temperature and irregular rainfall pattern has resulted in occurrence of diseases/pest in mountain ecosystem having adverse effect on agricultural production. Increase in temperature has opened revenue for introduction of new agro-biodiversity, whereas negatively resulted in loss of existing diversity.
