The change in these factors could result in a shift in their influence on land-use change. In land use studies so far, the focus has been on land-use change and not the state of the factors. Thus, this study focuses on the significance of drivers of land-use change between 1988 – 2009 in the Vietnamese Mekong delta. To assess how land-use change has been influenced by the shifts in environmental factors and the relationship between the observed shifts in influence and land-use change. The Vietnamese Mekong delta is one of the largest and most studied delta region in the world due to rapid increase in population and large-scale transformations driven by economic expansion in the last decades. Five land use types are considered in this study, these are; aquaculture, mixed crops, orchard, rice and urban. Each land use class was modelled using a logistic regression with the following environmental variables; compaction, elevation, population density, distance to river and sea, salinity and subsidence. The study period was divided into four; 1988 – 2006, 1988 – 1996, 1996 - 2006 and 2006 – 2009 to be able to observe a trend in land-use change. The findings of this study reveal that the significance of the selected environmental variables to land-use change is not constant over the study period. Some variables were not significant to land-use change in one or more periods, became significant in other periods or remained insignificant. The findings in this study provides decision makers with a better understanding on sustainable land-use planning in the study area and similar regions in the world.Verstegen, JudithMinderhoud, PhilipCosta, Ana Cristina Marinho daRUNAlsina, David Simduwa2021-03-15T12:29:39Z2021-01-292021-01-29T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10362/113891TID:202672956enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-03-11T04:56:42Zoai:run.unl.pt:10362/113891Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:42:24.028081Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
