• 21. Plant factories with artificial lighting (PFALs): Concluding remarks: Eri Hayashi and Toyoki Kozai, Japan Plant Factory Association, Japan;

Dr Toyoki Kozai is the former President of Chiba University, Japan, where he is now an Emeritus Professor. Professor Kozai is also the Honorary President of the Japan Plant Factory Association (JPFA) and a former President of The Agricultural Academy of Japan. As a pioneer of indoor plant factories with artificial lighting (PFALs), also referred to as indoor vertical farming, Professor Kozai is widely regarded as one of the founding figures in PFALs, and vertical farming. He has edited a number of books on PFALs and is the author of over 300 publications on controlled environment agriculture technologies.

Eri Hayashi is the President of the JPFA, where she is also the Director of International Relations and Consulting. She leads a number of international projects on technology development and has written widely on the topic of smart plant factories. Dr Hayashi has given presentations at a number of international conferences and has played a significant role in the organisation of the JPFA’s first International Symposium on Plant Factory in 2023.

“Despite being recognised as a mode of agricultural production for almost two decades, the vertical farming/plant factories industry is still considered to be in its early stages of development. In this time, technology has undergone important iteration processes which have been supported by science and practice-based research. Professor Toyoki Kozai and Dr Eri Hayashi have had a major influence on the advancement and global understanding of vertical farming. This new book, Advances in plant factories: New technologies in indoor vertical farming, addresses key topics such as energy modelling, the nutritional components of crops and spectral manipulation as a means of optimising vertical farming systems to achieve a more sustainable agriculture. We see tremendous value in this latest publication from Burleigh Dodds Science Publishing and are confident that it will become a standard reference book in this area.” (Christine Zimmermann-Lössl, Chairwoman of the Association for Vertical Farming, Germany)
