Land cover and management changes, influenced by agricultural policies since the early 20th century, notably during the wheat campaigns of the fascist regime, have exacerbated soil erosion, with the highest rates observed in vertical fallow (964\u2009g\u2009m<jats:sup>\u22122<\/jats:sup>\u2009yr<jats:sup>\u22121<\/jats:sup>), wheat (90\u2009g\u2009m<jats:sup>\u22122<\/jats:sup>\u2009yr<jats:sup>\u22121<\/jats:sup>) and horizontal fallow (66\u2009g\u2009m<jats:sup>\u22122<\/jats:sup>\u2009yr<jats:sup>\u22121<\/jats:sup>). These practices continue to be somewhat relevant today, as cereal production is still being subsidized. However, Quercus, Pines\u2014introduced since agrarian reforms and Portugal's entry into the common agricultural policy (CAP)\u2014and spontaneous vegetation from CAP's set\u2010aside policies and recent land abandonment trends show lower erosion rates, underlining vegetation's role in erosion protection. Using NDVI trend analysis, we distinguish between natural fluctuations and land cover changes impacts. Understanding these changes and how they relate to slope and valley floor dynamics, such as incision, aggradation or stabilization, is crucial for recognizing human influences on the earth's surface. Our research highlights sustainable land management's role in reducing soil erosion in desertification\u2010prone areas.<\/jats:p>","DOI":"10.1002\/ldr.4889","type":"journal-article","created":{"date-parts":[[2023,8,29]],"date-time":"2023-08-29T08:11:50Z","timestamp":1693296710000},"page":"5954-5968","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["The role of land use and land cover changes in triggering soil losses in the <scp>SE<\/scp> Alentejo, Portugal"],"prefix":"10.1002","volume":"34","author":[{"given":"Maria Jos\u00e9","family":"Roxo","sequence":"first","affiliation":[{"name":"Centro Interdisciplinar de Ci\u00eancias Sociais (CICS.NOVA), Faculdade de Ci\u00eancias Sociais e Humanas (FCSH) Universidade Nova de Lisboa  Lisbon Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5754-643X","authenticated-orcid":false,"given":"Henrique Morgado","family":"Cerqueira","sequence":"additional","affiliation":[{"name":"Centro Interdisciplinar de Ci\u00eancias Sociais (CICS.NOVA), Faculdade de Ci\u00eancias Sociais e Humanas (FCSH) Universidade Nova de Lisboa  Lisbon Portugal"}]},{"given":"Adolfo","family":"Calvo\u2010Cases","sequence":"additional","affiliation":[{"name":"Inter\u2010University Institute for Local Development, Department of Geography Universitat de Val\u00e8ncia  Valencia Spain"}]}],"member":"311","published-online":{"date-parts":[[2023,8,29]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/J.GEOMORPH.2008.03.001"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00546881"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.3390\/w11020240"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.iswcr.2020.10.002"},{"key":"e_1_2_10_6_1","volume-title":"Analysis of land use change: Theoretical and modelling approaches, Wholbk","author":"Briassoulis H.","year":"2000"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/J.JARIDENV.2020.104418"},{"key":"e_1_2_10_8_1","volume-title":"Concelho de M\u00e9rtola \u2013 geo\u2010biografia das mudan\u00e7as de uso do solo","author":"Casimiro P.","year":"1993"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ecohyd.2019.05.006"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1177\/0309133318758521"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.3390\/w12061539"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2018.08.141"},{"issue":"22","key":"e_1_2_10_13_1","first-page":"179","article-title":"Contribuition de L'\u00e9rosion selective du sols \u00e0 la sedimentation: Barrage Collinaire","volume":"11","author":"Dachary M.
