The two natural resources that are vital for agriculture are soil and climate. Man has no control as yet over the later and needs to adapt to it. Earth's climate is dynamic and always changing through the natural cycle. What we are experiencing now is part of this system. The nature of climate is sometimes complicated because of wide range of ecological and topographical diversities and hence requires in-depth studies to develop such adaptive measures. This is one of the challenging areas for agrometeorologists. Crop production forecasts are important to minimize risk in the food system-crop condition during the growing season and finally yield/production. Features: The book is intended to provide guidance to students and assist scientists on the practical application of some of the agrometeorological and agroclimatological tools in the area of short- and long-term agricultural planning as well as on the crop early warning and the drought monitoring with reference to dry-land agriculture in developing countries. To achieve such a goal presented natural variability in precipitation; a major component of climate change along with this presented in Annexure some basic aspects of meteorology and climatology. The other important area dealt in the book is the quantification and classification of agroclimate that facilitate transfer of location specific agricultural technologies developed by scientists from field trials & innovation technologies developed by progressive farmers.
