This book, Climate Change and Agricultural Policies: Science, Economics and Climate-Smart Transitions, offers a thoughtful synthesis of science, policy, and ethics to address the challenges of climate change in agriculture. Rooted in global frameworks such as the Intergovernmental Panel on Climate Change, World Meteorological Organization, and Food and Agriculture Organization, it explores pathways toward resilient and sustainable food systems.

The book introduces innovative concepts—PCCC, MCCC, and CCAC—forming an integrated approach to reduce cultivation costs, enhance productivity, and improve quality. Blending scientific rigor with human values, it serves as a guiding resource for farmers, students, policymakers, and researchers committed to building a climate-resilient agricultural future.

Dr. V. Radha Krishna Murthy is a globally recognized agrometeorologist and internationally acclaimed expert in climate-resilient agriculture. His pioneering work on “Weather, Health and Agriculture” has significantly advanced the understanding of the critical interface between climate change and sustainable agricultural systems.He holds academic qualifications of B.Sc. (Agriculture), M.Sc. (Agrometeorology), Ph.D. (Agronomy), and a Postgraduate Diploma in Environmental Studies. A merit scholarship holder throughout his academic career, Dr. Murthy also received the prestigious CSIR Fellowship and the FAO–ICAR–ANGRAU Fellowship.

With nearly four decades of distinguished experience in teaching, research, and extension, Dr. Murthy served as Senior Professor and Head in the field of agrometeorology and climate science. He is widely recognized as an international expert and has actively contributed to global knowledge dissemination through roving seminars on “Weather–Climate–Farmers.” He has also been an expert team member in several committees of the World Meteorological Organization, Geneva, Switzerland.

Dr. Murthy has received Best Teacher Awards at multiple levels in recognition of his excellence in education and mentorship. His innovative contributions include the development of several impactful concepts such as the policy concept on climate change, micrometeorological concept for climate change, comparison concept, blended weather technologies, daily weather-based agricultural planning, and the slate-and-pencil technique for farmer-level applications. He has also developed practical tools including a web-based Growing Degree Days (GDD) calculator, rainfall constants, and technologies for winter paddy nurseries.

A prolific author and scholar, Dr. Murthy has authored nine (9) books and manuals in agrometeorology, fourteen (14) books on agricultural education, and seven (7) international book chapters. He has published over 225 peer-reviewed scientific research papers and has presented extensively in national and international seminars, symposia, and workshops.This book stands as a testament to his lifelong commitment to advancing climate-resilient agriculture and nurturing informed, adaptive, and future-ready agricultural leaders. His work continues to inspire a paradigm shift in how agriculture is conceptualized and practiced in a changing climate.
