Design for the Other 90% explores over 30 projects that exemplify the growing movement among designers, engineers, students, architects, and social entrepreneurs to create affordable solutions for the approximately 90% of the global population, roughly 5.8 billion people, who lack access to essential products and services that many of us take for granted, including basic necessities like food, clean water, and shelter. This book, published alongside a significant exhibition at the Smithsonian's Cooper-Hewitt, National Design Museum, showcases the innovative approaches taken by individuals and organizations worldwide, both locally and globally, to improve access to vital resources such as food, water, shelter, healthcare, education, and energy for those in dire need. With contributions from renowned experts in the field, accompanied by 200 vibrant illustrations, Design for the Other 90% sheds light on a wide range of design solutions aimed at addressing the fundamental challenges faced by impoverished and marginalized communities, emphasizing the importance of design in fostering their survival and progress.
