In recent years increasingly, Public Administration has become a discipline with relevance not only to the national, the local and other sub-national levels, but also the transborder, regional, international and global service levels. Specific issues pertaining to institutional support and development structures, decision-making processes and their staffing have progressively become a focus of both training and research. This chapter focuses on these issues. It argues that developing and retaining a strong cadre of global public servants represent urgent imperatives, as well as preconditions for solutions to a growing list of global challenges. They range from global warming and climate change to poverty reduction, post-conflict reconstruction and socio-economic development. It is further argued that the creation of a cadre of global public servants is an important and necessary element of any strategy aimed at addressing the institutional challenges of global governance. The context, in which human resource development for global public service takes place, requires multilateral structures. These are needed to address skills shortages, particularly acute in the developing countries, while ensuring that the developed world, which benefits from the migration of skilled workers and professionals, offers something in return. The chapter proposes the establishment of a Global Public Service Academy to coordinate a global network of accredited institutions. The Academy could be established within the existing United Nations system. It should develop a set of minimum quality standards and criteria upon which institutions seeking accreditation would package and customise their programmes and course offerings.
