Crop Plants are inherently sensitive to climatic change and variability such as temperature and rainfall regimes as well as prevalence of extreme events. Understanding the adaptation mechanisms of agricultural crops to climate change is important to develop strategies for sustainable productivity under future climate scenario. This book provides a comprehensive account of climate change impacts on growth, yield and quality of important food and horticultural crops and their adaptations under Indian conditions. It includes the use of crop simulation models to analyse impact of climate change on agriculture, bioprospecting of genes for abiotic stress tolerance and options for improving photosynthetic efficiency.
The effect of climate change on crops-weed interactions, nutrient dynamics and rhizosphere and insect pest interactions is very crucial for developing strategies for climate change resilient agriculture. Variability in the pattern of rainfall is considered on e of the important challenges of climate change and may result in incidence of drought or floods in some regions. Understanding the molecular basis, identification of genetic sources for important adaptive traits in different crop plants for water deficit and waterlogging stress will be useful to develop new varieties suitable for these stress environments.
Bioprospecting of genes for climate change aims at the identification of the lock that influences the stress tolerance trait in a species adapted to stringent ecological stresses. It will lead to identification of novel and potential genes and promoters and to understand their molecular mechanisms. Impacts of climate change on the distribution, phenology and abundance of many pest species may cause large reductions in crop yield. This book is an invaluable tool for academics working in plant physiology, biochemistry, molecular biology, soil science, agronomy and entomology to develop new strategies for mitigation of the adverse impact of climate change on crops.
