Available Methodologies in Calculating the Ex-post Cost of Disaster: Case of Türkiye

Abstract

This paper explores the methodologies used in estimating the costs and losses of natural disasters, focusing on the Turkish experience following a series of unprecedented earthquakes in February 2023. The analysis emphasizes the need for a variety of methodologies to obtain a comprehensive understanding of the economic impacts of disasters. In the Turkish context, the Strategy and Budget Office (SBB) played a central role in coordinating post-disaster assessment efforts. By utilizing its expertise and coordinating data collection through local administrations and line ministries, the SBB ensured a swift and comprehensive analysis. Various methodologies, such as replacement cost, market valuation, and input–output analysis, were employed to estimate damages and losses in different sectors, and depending on data availability. The study highlights the importance of institutional capacity and expertise in conducting post-disaster assessments. It also emphasizes the need for a multi-method approach to capture the complexity of economic impacts.
