The book deals with (i) all aspects of the direct and indirect effects of weather and atmospheric elements on production, protection and water needs of crops (ii) influences of micro-climates, morphology, physiology and growth stages of crops in differential responses of crops to weather vagaries and weather-induced setbacks and (iii) agrometeorological (a) irrigation scheduling (b) forecasting of crop yields and pests and diseases (c) determination of incidence of crop drought and (d) advisory services. The effects of climate change on crops and cropping practices on global warming and means to mitigate such effects are detailed. Measures essential for achieving (i) cost-effective agricultural sustainability with environmental conservation in a steadily warming atomsphere and (ii) food-security are set out.
