The citrus industry plays a crucial role in the economies and agricultural landscapes of many Asian countries, contributing significantly to global citrus production and trade. Asian Citrus Industry: Growth and Sustainability provides a comprehensive analysis of the citrus sector across 14 major citrus-producing Asian nations, including China, India, Japan, Korea, Thailand, Bhutan, Nepal, Turkey, Pakistan, Bangladesh, Vietnam, Iran, Sri Lanka, and Indonesia. This book presents an in-depth exploration of the historical evolution, production trends, key challenges, and opportunities shaping the citrus industry in Asia. Each chapter delves into country-specific aspects including citrus production systems, major cultivars, post-harvest management, and production problems influencing the sector. It also highlights critical sustainability issues, including pest and disease management, technological innovations, and market-driven strategies that can enhance productivity and profitability for citrus growers.

By integrating a balanced blend of research insights, industry trends, and practical recommendations, Asian Citrus Industry: Growth and Sustainability serves as an essential reference for researchers, policymakers, agribusiness professionals, citrus growers, and students engaged in citriculture and horticulture. It provides valuable perspectives for those interested in understanding the diverse citrus ecosystems of Asia and exploring avenues for sustainable growth and international trade development.

Chandrika Ramadugu, PhD, is a Project Scientist in the Department of Botany and Plant Sciences, University of California Riverside, Riverside, California, USA. She earned her Ph.D. from the Indian Institute of Science, Bangalore, India. Since 2005, Ramadugu worked exclusively on citrus in Riverside, California. Her interests range from citrus pathology, development of pathogen detection assays, horticulture, taxonomy, genetic transformations, study of diverse citrus germplasm, genomic studies, and development of short-term and long-term solutions to the citrus huanglongbing disease that has been a major concern for citrus industries in the USA, Brazil, Central and South American countries, and citrus growing regions in Asia. Currently, Ramadugu and her team are developing novel hybrids with genetic resistance/tolerance to the citrus huanglongbing disease through genome-assisted breeding of citrus cultivars with disease-resistant Australian limes. Ramadugu has published research articles in peer-reviewed scientific journals and collaborates widely with scientists from various research organizations. She is the leading principal investigator in several federally funded multi-institution research grants focused on finding solutions to economically significant citrus diseases.
