This handbook exists thanks to the Center for Global Development’s decision to use its discretionary funding to enable research on a new and exciting topic: space and development. CGD’s blend of institutional curiosity, risk-taking, purpose, and support provided an ideal arena in which to thrive. My thanks in particular to Gyude Moore, Charles Kenny, Scott Morris, Anit Mukherjee, Clemence Landers, and Javier Guzman for many rich conversations ranging across geopolitics, economics, infrastructure, and development. Additional thanks to Parth Khare, Rowan Rockafellow, Shelby Bourgault and Jocilyn Estes, for lending expertise on such topics as geospatial data, development finance institutions and mechanisms, and gender equality and inclusion. I am delighted by and indebted to Stephanie Donohoe for successfully translating my sketches, handwaving, and intent into beautiful, informative graphics.
