International commissions, academics, practitioners, and the media have long been critical of the UN’s development efforts as disjointed and not fit for purpose; yet the organization has been an essential contributor to progress and peacebuilding.This handbook explores the activities of the UN development system (UNDS), the largest operational pillar of the organization and arguably the arena in which its ideational endeavors have made the biggest contribution to thinking and standards. Contributions focus on the role of the UNDS in sustainable social, economic, and environmental development, describing how the UNDS interacts with the other major functions of the UN system, and how it performs operationally in the context of the new 2030 development agenda focused on the 17 Sustainable Development Goals (SDGs).The volume is divided into three sections: Realizing the SDGs: opportunities and challenges; Resources, partnerships, and management; and Imagining the future of the UN in development. Comprised of chapters by knowledgeable and authoritative UN experts, this book provides cutting-edge and up-to-date research on the strengths and weaknesses of the UNDS, with each chapter focusing on different operational and ideational aspects.Chapter 11 of this book is freely available as a downloadable Open Access PDF at http://www.taylorfrancis.com under a Creative Commons Attribution-Non Commercial-No Derivatives (CC-BY-NC-ND) 4.0 license.
