Population and Landslide Risk Evolution in Long Time Series: Case Study of the Valencian Community (1920–2021)
Year: 2025
Type: article
Abstract: Assessing the size and situation of the population exposed to natural hazards is a fundamental step in addressing natural hazard management and emergency planning. Although much progress has been made in recent years in population geolocation by competent public bodies, gathering historical data beyond the present century to know the sequential evolution the affected population has experienced remains difficult. The recent publication of a historical population grid with adequate resolution allows progress to be made in resolving this problem. This paper is based on these data together with a map of landslide susceptibility in the study area and on the abundant resources provided by the Spanish cadastre on dates of construction, surface area and location of built plots. The size of the residential area built in the risk zone and its affected population was calculated since the early 1900s and with a decennial sequence. Through this, patterns of variation and possible causes could be provided that can help land managers establish objective criteria to prevent or mitigate landslide damage.
