Book excerpt: The Frugal Innovation and Bottom of the Pyramid Markets series comprises four volumes, covering theoretical perspectives, themes and various aspects of interest across four key geographical regions where BOP markets are located - South America, Asia, Africa and more engineered countries. BOP always addresses the poorest people or socioeconomic order or groups within a country, society, region or continent, thus, this series contributes a profound understanding of BOP markets across the most important geographical areas around the world and presents valuable insights on how the private sector can work together with other stakeholders to develop and operationalize economically viable business models in BOP markets, all the while contributing to sustainable development. Private actors such as multinationals, SMEs and entrepreneurs have a critical role to play in achieving the Sustainable Development Goals agenda as laid down by United Nations in September 2015. Yet, BOP markets face unique challenges and the private sector alone cannot orchestrate sustainable value creation activities. Each volume presents several theoretical strands that highlight the diverse approaches and solutions to developing BOP markets further. Frugal, reverse and inclusive innovations can foster (sustainable) development and provide new business models and value streams that other countries can also benefit from. A variety of stylistic elements, such as research work, interviews and roundtable discussions, offer a wide and vivid impression of ongoing challenges and fruitful solutions.
