Technologies for Sustainable Development is a specialized book that addresses the connection between scientific research and practical applications in development. It brings together the best 20 contributions from the 2012 conference of the EPFL-UNESCO Chair in Technologies for Development. The aim of the book is to explore ways in which scientific knowledge can be translated into practice to meet the social needs of developing countries and emerging markets. The authors emphasize that technologies must not only be cost-effective and affordable, but also socially, culturally, and ecologically accepted by users. The book discusses key issues related to appropriate technology, sustainable development, and the conditions for co-creation and transfer of such technologies. It promotes dialogue among various stakeholders to develop and implement the best solutions for social challenges.
