Under ongoing climate changes, natural and cultivated habitats of major crops are being continuously disturbed. Such conditions impose and exacerbate abiotic and biotic stressors. Drought, salinity, flood, cold, heat, heavy metals, metalloids, oxidants, irradiation, etc. are important abiotic stressors, while diseases and infections caused by plant pathogens, such as fungal agents, bacteria and viruses, are major biotic stresses. In many instances, stresses have become the major limiting factor for agricultural productivity and exert detrimental role on growth and yield of the crops. To help feed an ever increasing world population and to ensure global food security, concerted efforts from scientists and researchers have identified strategies to manage and mitigate the impacts of climate-induced stresses. This book, summarizing their findings, is aimed at crop improvement beyond such kind of barriers, by agronomic practices (genetics, breeding, phenotyping, etc.) and biotechnological applications, including molecular markers, QTL mapping, genetic engineering, transgenesis, tissue culture, various 'omics' technologies and gene editing. It will cover a wide range of topics under environmental challenges, agronomy and agriculture processes, and biotechnological approaches. Additionally, fundamental mechanisms and applied information on stress responses and tolerance will be discussed. This book highlights problems and offers proper solutions for crop stress management with recent information and up-to-date citations. We believe this book is suitable for scientists, researchers and students working in the fields of agriculture, plant science, environmental biology and biotechnology. 

Dr. Rajib Roychowdhury is presently working as Postdoctoral Visiting Scientist in the Institute of Plant Sciences of Agricultural Research Organization (ARO) - The Volcani Center, Israel Ministry of Agriculture and Rural Development, Israel. His current research is focusing on Winter Cereal Genetics and Breeding, especially to improve wheat. He received his Ph.D. in Plant Biotechnology from Visva-Bharati Central University (India) with the research on previously unreported rice landraces for their agro-morphology, grain quality and abiotic stress tolerance. Later, he also did short-term postdoctoral research under CSIR project (Government of India) on 'Metalloid stress tolerance in rice' from Assam Central University, Silchar, India. During Masters and post-masters' tenure, he worked a lot on mutation breeding in Carnation, which was a pioneer work on this floricultural crop in South-East Asia. He was elected as a Fellow Member of the Linnaean Society of London, UK. His biography was published in the Pearl Edition of Marquis Who's Who of the World, USA. In 2019, he got the travel award by International Wheat Initiative (Germany) for presenting his research in 1^st International Wheat Congress, Saskatoon, Canada. He has a plenty number of impacted research papers, review articles, invited chapters and books in both international and nationally reputed journals and publishers. Till date, his publications got a total of 1200 citations as per GoogleScholar with the h-Index 15. 

Dr. Shuvasish Choudhury is an Assistant Professor at Assam University, Silchar, India since 2009. He obtained his M.Sc., M.Phil. and Ph.D. in Life Sciences from Assam University, Silchar and Post Doctorate from Oklahoma State University, USA. He has published more than 40 research and review articles including book chapters in journals and volumes of national and international repute. He has been awarded Young Botanist Award by Indian Botanical Society in 2010 and thereafter with FAST TRACK Young Scientist Award and Overseas Associateship by SERB and Department of Biotechnology (DBT), Government of India.
