Humans have lived in adaptation to nature over long periods, but simultaneously, they have transformed nature and advanced culture by accumulating knowledge and technology. They have satisfied their needs and responded to environmental changes in various ways, expanding their habitats. In areas with water shortages, reservoirs and waterways were created, and levees were built around large rivers and lakes to fill low-lying lands. Reclamation is an act of transforming nature to create better environments. It began in the low-lying areas around large rivers and lakes and expanded to include filling tidal flats and seas.
Especially, the Saemangeum Reclamation Project in Korea represents the largest scale of dyke construction in the world, demonstrating humanity's capacity for change while forging a new future.
