Today's global challenges are bigger, more complex, and more intertwined than ever before, from the relentless grip of poverty and stubborn persistence of inequality to the devastations caused by climate disasters, fragility, pandemics, and conflicts. Financing and investments alone cannot solve these problems in a global context of higher debt and scarce resources. Now more than ever, clients are demanding innovative ideas and successful experiences from other countries to tackle the ongoing and emerging global crises, regain the development progress of past decades and move faster towards achieving the Sustainable Development Goals. At the same time, recent breakthroughs in technology, including the rapid advances in artificial intelligence, offer enormous potential to revolutionize development work. Policymakers and practitioners across the globe are poised to benefit from new tools to innovate, act based on evidence and accelerate the transformation of new ideas into development outcomes that improve lives of the poor. This paper articulates the strategic direction of the Knowledge Compact for Action, which seeks to empower all WBG clients, public and private, by systematically making the latest development knowledge available to respond more effectively to increasingly complex development challenges. The Compact seizes the opportunity of the digital revolution, bringing together the wealth of data analytics, research and best practices accumulated by the WBG over decades and combining this knowledge with the WBG's proven mix of public-private finance to power learning and innovative solutions. This includes capturing the tacit knowledge embedded in operations for policymakers and development practitioners to easily access lessons of development successes and failures in other countries. Ultimately, the Compact aims to take knowledge to a new level, placing it front and center of the WBG's work to end extreme poverty and boost shared prosperity on a livable planet.
