The impact assessment analysis of rising temperature on crops such as wheat, rice, maize, soybean, cotton and brassica are described, reviewed and discussed in separate chapters as case studies. The responses of physiological processes and biochemical reactions to the elevated temperature in crop plants are described crop wise. The monograph also includes the impact of elevating temperature on crop weed interaction, pest and diseases and soil dynamics for each crop species independently. The mitigation technologies to counter the adverse effect of high temperature stress are described for each crop according to their cultivation and climatic conditions. The future research strategies for each crop to meet the threat of elevating temperature on crop productivity and food security is described and discussed.
The description of temperature enrichment technologies will help researchers and scientists to study the responses of biological materials to rising temperature. The monograph will be the main text for teaching climate change, global warming and environmental botany as no such book is currently available relating to the rising atmospheric temperature on crop plants. Therefore, the monograph will be highly useful for students of global climate change, environmental botany and agricultural sciences, scientists, researchers, farmers and policy makers
Arranged according to the physical processes that aff ect the climate/plant relationship, the book is divided into two parts. The first part considers radiation fl ux in the free atmosphere and in the biosphere near the ground, the processes of photosynthesis and photoperiodism, and the effect of radiation and temperature on plant growth. The second part discusses in detail methods of determining or estimating both potential and actual evapotranspiration, the meteorological approach of computing water balance, and the eff ect of water on plant growth.
The author's clear and logical presentation of material, emphasizing general principles rather than experimental and technical details, makes this book especially useful for students of agricultural climatology. The broad scope of the work and its comprehensive survey of the literature make it equally a valuable reference for professionals in physical geography, meteorology, agronomy, botany, plant physiology, soil science, and hydrology.

Alternative methods of irrigation are presented, emphasising the characteristics of each that may make them suitable (or unsuitable) for particular situations. The range of crops under irrigation is very wide, and so too is the range of methods available to get water to them. Horticultural crops are included as well as broadacre crops. This section is followed by technical information of the various components that make up an irrigation system, and their installation.
Irrigation is concerned with providing the optimum soil moisture conditions for plant growth. So to is drainage, in that too much water in the soil will retard growth. Many of the concepts surrounding irrigation are applicable to a consideration of drainage, so the book discusses that technology as well.
