The thesis deals with land use changes in field Krševo polje on Dugi otok Island from the 19th century until the present day. Land use changes of municipality Sali, especially in the Krševo polje, were influenced by the natural geographical and socio-geographical factors. The main scope of the research was to determine the way Krševo polje has been changing throughout the history as well as to determine how much the official state from the cadastre survey coincides with the current way of land use. The current land state is determined by the field research of Krševo polje. Natural geographical factors such as climatological, hydrological and the geological characteristics that impacted the development of the agriculture in the Krševo polje were analysed as well. The changes in demographic and economic structures are the most important elements in the landscape shaping. Depopulation and the development of the secondary and the tertiary activities greatly influenced the abandonment of the agricultural areas. In the second half of the 20th century, opening of the new factory plants for the fish processing demanded more work force in that sector, hence the population re-oriented themselves onto that industry. In the 21st century, the tertiary activities became more important, primarily tourism that became the main source of income for the majority of the island residents. Researching land use changes in the cadastre lots showed a detailed picture of how Krševo polje has been used for the last two centuries. According to the cadastral survey from the end of the 19th century, the majority of the field was covered with olive groves and vineyards, as olive growing and viticulture were two main agricultural branches. Due to the developed livestock breeding, the fields were covered with huge pastures that were used for the livestock grazing. From the second half of the twentieth century,the usage of the fields has changed completely. Decrease in the number of islanders and development of the industry has led to the abandonment of agriculture, and with that, to the decrease of the area that is being cultivated. Field research affirmed that majority of the field is covered with forest vegetation, and territory that is pedologically the most valuable is uncultivated for the most part and is covered with the autochthonous vegetation. During the last two centuries, the parcellation occurred and resulted in greater number of landlords per cadastral lots. Unresolved property and legal relations significantly influenced the adequate usage of agricultural areas. The purpose of this thesis is to highlight the need for the regular update of cadastral records for the purpose of the adequate space planning and the creation of spatial plans.
