Usage of land resources to meet the demands of human being has an impact on the land resources. The purpose of the study was to investigate the land resource usage constraints and their temporal change in Bale Eco Region, Southeast Ethiopia. Both qualitative and quantitative cross sectional study designs were employed. Data was collected using HH survey, in depth interview, focus group discussion and field observation. Data analysis, descriptive and inferential statistics were implemented by using SPSS software version 20. Chi-Square test, frequencies and percentage were used to compare differences among variables with respect to the three agro-ecologies and statistical significance was decreased at P ≤ 0.05. Qualitative data was first transcribed to texts in local language then retranslated to English for writing the report. Data analysis was done after categorizing the transcripts. The information obtained from quantitative and qualitative sources were triangulated to ensure the relevance of the results of the study. Based on the finding of the study trends of land holding probability (p=0.00) and land productivities= (0.00), were significantly difference. Physical, technological and extension services were among the constraints that are identified to influence land and other natural resources utilization in the three agro-ecologies of BER. Lack of technology and lack of science based knowledge were among of the critical constraints that reported by majority of the respondents that limit them from utilizing their land resources. Almost in all agro-ecologies, low and erratic rainfall, climate variability, drought, inaccessibility, lack of water sources was the common constraints of. It is recommended that concerned bodies should minimize constraints of responsible land resource utilizations and temporal natural resources degradation in BER.
