Structural measures involve physical construction projects designed to reduce disaster risk, such as dams, levees, sea walls, and shelters. Non-structural measures do not involve physical infrastructure but rather use strategies like building codes, education, early warning systems, land use planning, and legislation to manage risk. Examples of structural measures for different hazards include reinforced construction, drainage systems, and tree planting; non-structural examples consist of enforcement of policies, financial incentives, environmental management, and knowledge sharing programs.
