Food safety and health have become a crisis due to the inappropriate and indiscriminate use of Chemical inputs. Considering the importance of the subject, the present research was conducted with the aim of analyzing and identifying the most important factors affecting food security, with an emphasis on organic agriculture in Tabriz County. This research is based on a mixed approach and on practical purposes. The statistical population of this research is the expert agricultural jihad of Tabriz County. In terms of collecting information, it was done in two forms: library and field, using semi-structured interviews. The statistical sample was initially conducted using targeted sampling and then using the snowball method with 16 people until theoretical saturation was reached. Qualitative data analysis was done using the six-step theme model. MAXQDA software was used to code the interviews. The reliability of the interview was checked using the retest method (within the subject). Acceptability and verifiability methods were used to measure validity. The results of the qualitative section included eight main themes, 28 sub-themes, and 62 optional themes. Acceptability and verifiability methods were used to measure validity.

Over time, patterns of land Use changes and consequently the land use are essentially altered. Thus for efficient using of capabilities of natural resources, finding detailed information about potential of land uses is necessary. Nowadays, remote sensing technology as a valuable approach to identify natural resources, particularly in the process of preparing land use plans in different regions of the world are documented scientifically. On this basis, for studying the land use changes of Tabriz county during 2010, 2007, 2001, 1989; TM 1989, ETM 2001&+2010, IRS 2007 images were processed and classified by an object-oriented technique. Then, bypre-classification comparing method, all changes were displayed during time period. The results show that the rate of changes over periods of 1989-2001, 2001-2007, 2007-2010, 1989-2010 are about 60.80, 66.30, 56.80, 56.40 percent respectively, so that vegetation cover and the water surfaces had the maximum changes. Meanwhile the most using conversion had happened on built-up lands.
