Property and land titles in Brazil is a serious problem, where the absence of a legal situation causes a rural exodus, legal insecurity and the impossibility of obtaining credit for agricultural activities. The objective of this research was to develop a methodology of multiple-criteria decision analysis in the selection of priority areas for land regularization in the State of Bahia (Northeast Brazil). The municipal variables used in the model were: municipal human development index, gross production value, the number of farmers without land documents, the proportion of family farms, slope, and registered properties. The data processing methods used were the Analytic Hierarchy Process (AHP) and Fuzzy AHP. The result was a cartographic synthesis map based on the arithmetic mean of these models, containing the following priority classes: high, medium, low and non-priority. The proposed method determined 128 priority municipalities for immediate land regularization actions with a threshold value exceeding 0.66 and 22 extremely priority municipalities with a threshold higher than 0.80. These priority municipalities have a continuous spatial pattern along the São Francisco river depression. The large number of possessions and the small number of registered areas in the State of Bahia indicate the importance of systematic actions for the spatial registration and the land regularization.
