For over 70 years, the United Nations has worked to advance human conditions globally through its historic agenda for a more peaceful, prosperous, and just world. Through the work of the General Assembly and other programs like the UNESCO World Conferences on Adult Education, the organization has taken a leading role in bringing world leaders together to dialogue on world issues and to set agendas for advancing social and economic justice among and within the regions of the world. The underlying themes of the United Nations' agenda over the years have been world peace, economic justice, addressing the needs of the world's most vulnerable populations, and protecting the environment. We draw from the two last two declarations from which the Millennium Development Goals (September 2000) and the Sustainable Development Goals (September 2015) were adopted by world leaders with a focus on addressing the needs of the most vulnerable populations. In this declaration, world leaders committed to uphold the long-standing principles of the organization and to combat extreme poverty, hunger, disease, illiteracy, environmental degradation and discrimination and violence against women.

The overall objective of the book is to highlight the conditions of vulnerable populations from various contexts globally, and the role adult and higher education can play (and is playing) in advancing the United Nations agenda of social and economic justice and environmental sustainability. Adult education, through research, teaching, and service engagements is contributing to this ongoing effort but as many scholars have noted, our work remains invisible and undocumented. Therefore, this book highlights adult education's critical partnership in addressing these global issues. It will also begin to fill the void that exists in adult education literature on internationalization of the field.
