The resources of both governments and traditional philanthropy are either barely growing or in decline, yet the problems of poverty, ill-health, and environmental degradation balloon daily. It is therefore increasingly clear that we urgently need new models for financing and promoting social and environmental objectives. Fortunately, a significant revolution appears to be underway on the frontiers of philanthropy and social investing, tapping not only philanthropy, but also private investment capital, and providing at least a partial response to this dilemma. This book examines the new actors and new tools that form the heart of this revolution, and shows how they are reshaping the way we go about supporting solutions to social and environmental problems throughout the world. With contributions from leading experts in the field, New Frontiers of Philanthropy provides a comprehensive analysis of the many new institutions that have surfaced on this new frontier of philanthropy and social investment; the new tools and instruments these institutions are bringing to bear; the challenges that these actors and tools still encounter; and the steps that are needed to maximize their impact. The result is a powerful and accessible guide to developments that are already bringing significant new resources into efforts to solve the worlds problems of poverty, ill-health, and environmental degradation; unleashing new energies and new sources of ingenuity for social and environmental problem-solving; and generating new hope in an otherwise dismal scenario of lagging resources and resolve. Investors, philanthropists, social entrepreneurs, nonprofit leaders, business executives, government officials, and students the world over will find much to build on in these pages.
