Climate Change and Indian Agriculture: Challenges and Adaptation Strategies

Not AvailableNoNatural and human activities have increased the greenhouse emissions and st it will continue to boost global temperature in the 21 century. In this paper, we discuss the profound impact of climate on plant diseases — if the climatic conditions are not favourable to disease, a vulnerable host will not be infected by a virulent pathogen. Variable concentrations of CO , temperature, and availability 2 of water may induce positive, neutral, or negative effects on disease development. Nevertheless, the basic concept of interactions of host-pathogen-environment may theoretically be applied to all pathosystems.
