Human Resource Development is a very important scientific topic in the world today and due to the globalization process, it will only become more important in the next decades. This happens because the effort to develop in a sustained way the world will need more and more talent. In this context, we do not believe robots or Artificial Intelligence and digitalization will decrease the need for Humans in organizations; quite on the contrary we consider that the so-called 4.0 revolution will only increase the need for more highly developed human potential. It is within this context that we believe a Handbook of Research on Human Resource Development will be important because it will help individuals, organization managers, and national deciders to invest in HRD. The book is needed because it fills a gap given that many disperse publications exist but no one that really covers in 25 chapters the essence of the topic. Researchers from all disciplines covering business sciences and social and human sciences working on a range possible topic of the project. This project will emphasize the importance of HRD in the current and future context. Learning and development are fundamental to the digital and technological world. Researchers will be encouraged to push the boundaries of their respective disciplines and to see how theories and methodologies can be used to design rich research projects to study the complex dynamics and interactions of HRD. This project is an opportunity to involve several stakeholders, including professionals from public and private companies, human resources professionals, specialists, academics, and researchers from several countries.
