Moreover, the changing climate is assumed to have an impact on landslide occurrences in the future. The aim of this study is to conduct the first landslide susceptibility mapping (LSM) in Denmark, reducing the geographical bias existing in LSM studies, and to identify areas prone to landslides in the future following representative concentration pathway RCP8.5, based on a set of explanatory variables in an area of interest located around Vejle Fjord, Jutland, Denmark. A subset from the landslide inventory provided by GEUS is used as ground truth data. Three well-established machine learning (ML) algorithms\u2014Random Forest, Support Vector Machine, and Logistic Regression\u2014were trained to classify the data samples as landslide or non-landslide, treating the ML task as a binary classification and expressing the results in the form of a probability in order to produce susceptibility maps. The classification results were validated through the test data and through an external data set for an area located outside of the region of interest. While the high predictive performance varied slightly among the three models on the test data, the LR and SVM demonstrated inferior accuracy outside of the study area. The results show that the RF model has robustness and potential for applicability in landslide susceptibility mapping in low-lying landscapes of Denmark in the present. The conducted mapping can become a step forward towards planning for mitigative and protective measures in landslide-prone areas in Denmark, providing policy-makers with necessary decision support. However, the map of the future climate change scenario shows the reduction of the susceptible areas, raising the question of the choice of the climate models and variables in the analysis.<\/jats:p>","DOI":"10.3390\/ijgi11060324","type":"journal-article","created":{"date-parts":[[2022,5,28]],"date-time":"2022-05-28T01:40:45Z","timestamp":1653702045000},"page":"324","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Landslide Susceptibility Mapping Using Machine Learning: A Danish Case Study"],"prefix":"10.3390","volume":"11","author":[{"given":"Angelina","family":"Ageenko","sequence":"first","affiliation":[{"name":"Department of Planning, Aalborg University, Rendsburggade 14, 9000 Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L\u00e6rke Christina","family":"Hansen","sequence":"additional","affiliation":[{"name":"Department of Planning, Aalborg University, Rendsburggade 14, 9000 Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kevin Lundholm","family":"Lyng","sequence":"additional","affiliation":[{"name":"Department of Planning, Aalborg University, Rendsburggade 14, 9000 Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3882-0392","authenticated-orcid":false,"given":"Lars","family":"Bodum","sequence":"additional","affiliation":[{"name":"Department of Planning, Aalborg University, Rendsburggade 14, 9000 Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6347-2935","authenticated-orcid":false,"given":"Jamal Jokar","family":"Arsanjani","sequence":"additional","affiliation":[{"name":"Department of Planning, Aalborg University, Rendsburggade 14, 9000 Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Highland, L.M., and Bobrowsky, P.
