Aside from residential areas, the location is also home to a Global Campus, Pharma Hub, Startup Center, and international organizations such as the Green Climate Fund.[5] Built on 600 ha (1,500 acres) of land reclaimed from the Yellow Sea off Incheon, about 56 km (35 mi) from the South's capital Seoul, Songdo district was one the largest private real estate developments in history[citation needed].[7] The Songdo IBD was part of former President Lee Myung-bak's effort to promote green and low-carbon growth as an avenue for future development after 60 years of reliance on export-oriented manufacturing.Under this initiative, the Songdo IBD is being developed as a sustainable city with more than 40% of its area reserved for green space, including the park of 40 ha (100 acres), 26 km (16 mi) of bicycling lanes, numerous charging stations for electric vehicles and a waste collection system that eliminates the need for trash trucks.In spring 2014, George Mason University (Fairfax, Virginia) opened its Korean campus in Songdo to support undergraduate academic interests and professional development programming for local corporations.Prior to reclamation, the Songdo tidal flats had supported several threatened waterbird species, and provided a staging ground for migratory waders as they traveled between the Northern and Southern hemispheres.
