About the Book
Climate change is exerting profound and increasingly complex pressures on global agriculture, threatening food security, ecosystem viability and rural livelihoods worldwide. While past gains in crop productivity have been realized largely using fertilizers, agrochemicals, and intensive farming practices, these methods rely on finite resources and pose long-term environmental and economic sustainability challenges. In this context, recent advancements in genomics are transforming crop improvement by facilitating a shift from input-intensive practices toward knowledge-driven, climate-smart and sustainable agricultural systems. The rapid expansion of high-quality crop reference genomes, driven by the widespread adoption of high-throughput sequencing, long-read technologies and advanced assembly platforms, has ushered in the era of pangenomes and super-pangenomes. These genomic frameworks capture the full spectrum of allelic, structural and haplotypic diversity, providing unprecedented opportunities to discover, deploy and stack climate-adaptive traits. As a result, genomics-assisted breeding is now enabling the precise identification of quantitative trait loci, genomic regions and genes associated with abiotic and biotic stress tolerance, as well as improved resource-use efficiency and yield stability. This book provides a comprehensive and forward-looking synthesis of how climate change is reshaping agriculture and how cutting-edge genomic technologies can be leveraged to deliver resilient, high-performing and environmentally sustainable crops. It will appeal to researchers in plant genetics, breeding and genomics, and also to crop breeders, plant biotechnologists, environmental scientists and policymakers.

About the Author :
Rajeev K Varshney (Edited By)
Rajeev Kumar Varshney FRS is an Indian agricultural scientist, specializing in genomics, genetics, molecular breeding and capacity building in developing countries. Varshney is currently serving as Director, Western Australian State Agricultural Biotechnology Center; Director, Centre for Crop & Food Innovation; and International Chair in Agriculture & Food Security with the Food Futures Institute at Murdoch University, Australia since Feb 2022.[1] Before joining Murdoch University, Australia he served International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), a global agriculture R&D institute, for more than 16 years in different scientific and research leadership roles including Research Program Director for three global research programs- Grain Legumes, Genetic Gains and Accelerated Crop Improvement Program. He has the onus of establishing and nurturing the Center of Excellence in Genomics & Systems Biology (CEGSB), a globally recognized center for genomics research at ICRISAT that made impacts on improving agriculture and development of human resources in several countries including India, China, Kenya, Ethiopia, Tanzania, Nigeria, Ghana, Mali, Senegal, Burkina Faso, etc. Varshney holds Adjunct/Honorary/Visiting Professor positions at 10 academic institutions in Australia, China, Ghana, Hong Kong and India, including The University of Western Australia, University of Queensland, West Africa Centre for Crop Improvement (University of Ghana), University of Hyderabad, Chaudhary Charan Singh University and Professor Jayashankar Telangana State Agricultural University. Varshney is a globally recognized leader for his work on genome sequencing, cataloguing and utilizing genetic diversity, genomics-assisted breeding, seed system and capacity building in developing countries. He has made centrally important contributions towards improving food and nutrition security in India and several countries in Africa and Asia by assembling genomes, developing genomic resources and integrating genomic technologies in crop improvement programs in many tropical crops, and delivering several superior crop varieties to some of the world's poorest farmers. His research group at present at Murdoch University is working on improving wheat, legume and horticultural crops for a range of agronomic, and abiotic stress tolerance traits by developing and deploying novel genomics and pre-breeding approaches such as pangenomics, haplotype cataloguing and functional genomics approaches.
Richard Harper (Edited By)
Richard Harper is a Professor in the Food Futures Institute within Murdoch University. His research focuses on developing innovative strategies for managing soil, water, and biodiversity-fields that face numerous persistent and complex challenges globally. His primary emphasis is on leveraging carbon markets to facilitate large-scale changes in landscapes; this approach not only addresses these complex issues but also tackles global greenhouse gas emissions, enabling both governments and industries to fulfill their ambitious commitments to reduce emissions. His research has explored the significance of carbon sequestration and bioenergy in various contexts, including agricultural lands, plantations, natural forests, rangelands, and coastal environments. Concurrently, a related program is examining solutions for soil water repellency, which poses significant challenges in agricultural and forested lands. He became a part of Murdoch University in 2009, after accumulating two decades of scientific and policy experience with the Western Australian Government. He was a lead author on the Intergovernmental Panel on Climate Change's Fifth Assessment Report and has served on a range of Australian Government committees.
